Criminal Appeals and International Judicial Cooperation in India: Appellate Review, Extradition, and Mutual Legal Assistance

Criminal Appeals and International Judicial Cooperation in India: Appellate Review, Extradition, and Mutual Legal Assistance

Introduction

A criminal justice system must do more than investigate offences, determine guilt, and impose punishment. It must also provide mechanisms through which decisions can be challenged, procedural errors corrected, unlawful convictions reversed, and sentences reviewed. At the same time, criminal activity increasingly crosses national borders. Suspects may leave the country in which an offence was committed, evidence may be held by foreign banks or technology companies, witnesses may reside abroad, and proceeds of crime may be transferred through several jurisdictions. These realities make appellate review and international judicial cooperation essential parts of modern criminal justice.

In India, criminal appeals are principally governed by the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS), which replaced the Code of Criminal Procedure, 1973, subject to the applicable savings provisions. The BNSS establishes the ordinary appellate structure, identifies the persons entitled to appeal, regulates appeals against convictions and acquittals, and provides procedures for the consideration of appeals by the High Courts and the Supreme Court. Constitutional remedies and special statutory appeal mechanisms operate alongside this general framework.

International cooperation is governed by a different but closely connected body of law. Extradition is principally regulated by the Extradition Act, 1962, together with applicable treaties, arrangements, and principles of international law. Mutual legal assistance enables Indian authorities to obtain evidence, documents, testimony, financial information, and other investigative assistance from foreign states, while also allowing India to respond to comparable requests from abroad. The BNSS contains provisions concerning assistance in criminal matters with foreign countries, including the transmission of requests and the use of evidence obtained through international cooperation.

These mechanisms serve distinct purposes. An appeal asks whether a domestic criminal decision should be reconsidered by a higher court. Extradition seeks the surrender of a person by one state to another for prosecution or enforcement of a sentence. Mutual legal assistance concerns cooperation in obtaining evidence and other forms of assistance without necessarily transferring the person concerned.

The three mechanisms nevertheless form part of a connected system. A criminal prosecution may involve an investigation conducted with foreign assistance, the extradition of an accused person, a trial in India, and a subsequent appeal. Understanding their legal foundations, institutional responsibilities, procedural safeguards, and limitations is therefore necessary to understand the administration of criminal justice in India.

1. The Legal Framework Governing Criminal Appeals in India

1.1 The transition from the Code of Criminal Procedure to the BNSS

The BNSS is the principal legislation governing criminal procedure in India. It replaced the Code of Criminal Procedure, 1973, with effect from 1 July 2024, subject to statutory savings for proceedings and matters governed by the earlier legislation.

The appellate framework is contained in the BNSS provisions dealing with appeals, revisions, and references. These provisions regulate the circumstances in which a person may challenge a criminal judgment, the courts competent to hear an appeal, the powers available to appellate courts, and the procedures that must be followed.

The statutory framework operates alongside the Constitution of India. In particular:

• Article 134 provides for specified categories of criminal appeals to the Supreme Court.
• Article 136 gives the Supreme Court discretionary power to grant special leave to appeal.
• Article 137 concerns the Supreme Court’s power to review its judgments and orders.
• Article 21 protects life and personal liberty and informs the interpretation of fair criminal procedure.
• Articles 14 and 22 provide additional constitutional safeguards relevant to criminal proceedings.

An important distinction must be maintained between an appeal created by statute and a constitutional remedy. A statutory appeal exists because legislation expressly provides for it. A constitutional remedy may arise under the Constitution itself and is subject to its particular conditions and limitations.

1.2 The principle that there is no automatic right of appeal in every criminal case

Unlike the right to a fair trial, which is protected through constitutional and statutory guarantees, the right to appeal is not unlimited. Indian law generally treats an appeal as a statutory right. A person cannot assume that every interlocutory order, procedural ruling, or criminal judgment is automatically appealable.

The availability of an appeal depends on the governing statute, the nature of the decision, the identity of the appellant, and any applicable restrictions.

For example, the BNSS provides appeals against specified convictions, acquittals, and sentences. It also identifies situations in which an appeal is unavailable, including certain cases where the accused has pleaded guilty, subject to statutory exceptions.

Special legislation may create additional appellate routes. Laws dealing with terrorism, corruption, economic offences, narcotics, and other specialised areas may establish particular forums, procedures, or limitations. The general BNSS framework must therefore be read together with the legislation governing the particular offence.

The statutory nature of appeals does not mean that appellate review is unimportant. Rather, it means that the legislature defines the circumstances in which a higher court may reconsider a criminal decision.

1.3 The purposes of criminal appellate review

Criminal appeals perform several functions.

First, they provide a mechanism for correcting legal errors. A trial court may misinterpret a statutory provision, apply an incorrect legal test, misunderstand the burden of proof, or rely on evidence that should not have been admitted.

Second, appellate review may correct factual errors. A trial court may misunderstand testimony, overlook material contradictions, draw unreasonable inferences, or reach a conclusion unsupported by the evidentiary record.

Third, appeals protect procedural fairness. A conviction may be challenged where the accused was denied a meaningful opportunity to defend the case, where mandatory procedural requirements were ignored, or where the trial was affected by serious irregularity.

Fourth, appellate decisions promote consistency in the interpretation of criminal law. High Court and Supreme Court judgments clarify statutory provisions and establish principles that guide lower courts.

Finally, appellate review provides institutional accountability. It ensures that the exercise of criminal jurisdiction is subject to legal scrutiny and that the finality of a trial judgment does not make it immune from correction.

2. The Structure of Criminal Appellate Jurisdiction

2.1 Appeals to the Court of Session

The Court of Session exercises appellate jurisdiction over specified criminal decisions of subordinate courts within its territorial and statutory jurisdiction.

The BNSS provides for appeals from certain convictions and sentences imposed by Magistrates. The precise appellate route depends on the nature of the conviction and the sentence imposed.

A Sessions Court may examine the record, consider the legal and factual grounds raised by the appellant, and exercise the powers granted by the BNSS. Its role is not merely administrative. It is a judicial forum capable of reviewing the correctness and legality of the challenged decision.

2.2 Appeals to the High Courts

High Courts occupy a central position in the Indian criminal appellate structure. They hear appeals from specified decisions of Sessions Courts and other courts where the BNSS or a special statute confers appellate jurisdiction.

Their powers include reviewing convictions, acquittals, and sentences in the circumstances prescribed by law. They may also exercise revisional jurisdiction and constitutional jurisdiction, although these are distinct forms of judicial supervision.

High Courts have a particularly important role in maintaining consistency within their respective jurisdictions. Their decisions bind subordinate courts within the relevant territorial jurisdiction, subject to the constitutional position of the Supreme Court.

2.3 Appeals to the Supreme Court

The Supreme Court is the highest judicial authority in India. Its criminal appellate jurisdiction arises principally from Articles 134 and 136 of the Constitution, together with statutory provisions.

Article 134 provides for appeals in specified criminal cases. These include certain cases in which a High Court has reversed an acquittal and sentenced an accused person to death, withdrawn a case for trial before itself and convicted the accused, or certified that the case is fit for appeal to the Supreme Court.

Article 136 gives the Supreme Court broad discretionary authority to grant special leave to appeal from judgments, decrees, determinations, sentences, or orders of courts and tribunals in India, subject to the constitutional exclusion relating to courts or tribunals constituted by or under laws relating to the Armed Forces.

Special leave is not an ordinary appeal available as of right. It is an exceptional constitutional remedy through which the Supreme Court may intervene where the circumstances justify its discretionary jurisdiction.

2.4 The relationship between appellate and revisional jurisdiction

Appeals and revisions are related but legally distinct.

An appeal ordinarily exists because a statute expressly provides a right to challenge a particular decision. It may permit review of both factual and legal questions, depending on the applicable provision.

Revision is a supervisory jurisdiction designed to examine the legality, correctness, propriety, or regularity of specified judicial proceedings and orders. It is not generally intended to operate as a substitute for an appeal.

The distinction is important because a party cannot ordinarily avoid the statutory restrictions governing appeals simply by presenting the same challenge as a revision. Revisional jurisdiction is subject to its own statutory limitations and principles of judicial restraint.

The BNSS also regulates the relationship between appeals and revisions, including circumstances in which a court may decline to entertain a revision where an appeal was available but not pursued.

3. Appeals Against Conviction

3.1 The accused person’s right to challenge a conviction

A person convicted of a criminal offence may appeal where the BNSS or another applicable statute provides a right of appeal.

The grounds may include:

• an error in the interpretation or application of criminal law;
• an incorrect assessment of evidence;
• reliance on inadmissible or improperly obtained evidence where the law makes the error relevant;
• failure to consider material defence evidence;
• an unreasonable conclusion about the accused’s intention or knowledge;
• incorrect application of the burden or standard of proof;
• denial of procedural fairness;
• an unlawful or disproportionate sentence; or
• a material irregularity affecting the validity of the proceedings.

The appellant must identify the challenged findings and explain why the decision should be altered. An appellate court is not required to accept every disagreement with the trial court’s reasoning as a sufficient basis for intervention.

3.2 Appeals following a guilty plea

The BNSS restricts appeals in certain cases where a person has pleaded guilty and has subsequently been convicted.

The statutory position depends on the court in which the conviction occurred and the nature of the sentence. In specified circumstances, the appeal may be limited to the legality or extent of the sentence rather than the conviction itself.

The underlying principle is that a voluntary and legally valid guilty plea may narrow the issues available for appellate consideration. However, a guilty plea does not necessarily eliminate every possible challenge. Questions concerning jurisdiction, legality of sentence, voluntariness, or compliance with mandatory legal requirements may remain relevant under the applicable provision.

3.3 Appeals against sentence

A person may challenge a sentence where legislation permits an appeal. The grounds may concern the legal authority to impose the punishment, the application of statutory sentencing limits, or the manner in which the court exercised its discretion.

An appellate court may examine whether the trial court considered relevant aggravating and mitigating circumstances, whether the sentence is authorised by law, and whether the sentencing decision reflects applicable legal principles.

A sentence may be challenged even where the conviction itself is not disputed, provided the relevant statutory appeal is available.

3.4 Appeals involving multiple offences

Where a person has been convicted of several offences, the appellate court may need to examine each conviction and sentence separately.

A successful challenge to one count does not automatically invalidate every other conviction. The court must determine whether the challenged error affects the remaining findings, whether the offences are legally and factually separable, and whether the sentences are concurrent or consecutive.

This is particularly important where a trial involves several accused persons, multiple transactions, or offences arising from a connected course of conduct.

4. Appeals Against Acquittal

4.1 The legal significance of an acquittal

An acquittal is a judicial determination that the prosecution has not established criminal responsibility to the standard required by law.

The presumption of innocence is not extinguished merely because a trial has taken place. An acquittal reinforces the legal position that the accused cannot be treated as guilty unless the prosecution establishes guilt through a legally valid process.

The appellate review of an acquittal must therefore respect the special significance of the presumption of innocence and the trial court’s assessment of evidence.

4.2 Appeals by the prosecution

The BNSS permits appeals against acquittals in specified circumstances. The prosecution’s ability to challenge an acquittal depends on the statutory route, the authority bringing the appeal, and any required permission or leave.

An appeal by the State is not equivalent to a fresh prosecution. The appellate court reviews the legality and evidentiary basis of the acquittal within the applicable appellate framework.

The prosecution must demonstrate a legally sustainable reason for interference. A mere preference for a different interpretation of the evidence will not necessarily justify reversal.

4.3 Appeals by victims

The BNSS recognises a victim’s right to appeal against an acquittal, a conviction for a lesser offence, or the imposition of inadequate compensation, subject to the statutory framework.

The victim’s right is important because the interests of the person harmed by an offence are not necessarily identical to those of the prosecution. A victim may have a legitimate interest in challenging an acquittal or an inadequate legal outcome even where the prosecution’s position differs.

The victim’s statutory right must nevertheless be exercised in accordance with the prescribed procedure and applicable limitation requirements.

4.4 The double presumption of innocence

Indian appellate jurisprudence recognises that an acquittal strengthens the presumption of innocence.

Where two reasonable views of the evidence are possible, the appellate court will ordinarily be reluctant to replace the trial court’s view merely because it prefers another interpretation. Interference may be justified where the acquittal is unreasonable, perverse, based on a material misreading of evidence, or contrary to settled legal principles.

This approach balances the need to correct miscarriages of justice with the importance of finality and the protection of persons who have been acquitted.

5. The Procedure for Criminal Appeals

5.1 Filing the appeal

A criminal appeal must be presented to the competent court in the form and manner prescribed by the BNSS or the applicable special statute.

The appeal generally identifies:

• the judgment or order challenged;
• the court that delivered the decision;
• the date of the decision;
• the appellant’s legal grounds;
• the relief requested; and
• any relevant supporting documents or applications.

The appellant must comply with the applicable limitation period, court rules, filing requirements, and procedural directions.

5.2 Limitation periods and delayed appeals

Criminal appeals are subject to statutory and procedural time limits. These limits promote legal certainty and prevent challenges from remaining indefinitely unresolved.

However, delay may sometimes be condoned where the applicable law permits and sufficient cause is established. The court considers the explanation for the delay and the interests of justice.

The availability of condonation does not mean that limitation periods are optional. An appellant should not assume that a late appeal will automatically be admitted.

5.3 Preparation of the record

The appellate court ordinarily requires access to the relevant trial record. This may include the judgment, depositions, exhibits, documentary evidence, orders, and other material necessary to determine the appeal.

The record allows the appellate court to evaluate whether the trial court correctly understood the evidence and applied the law.

In appropriate cases, the appellate court may call for additional material or take further evidence in accordance with the statutory provisions. Such powers are not intended to permit an unrestricted retrial.

5.4 Suspension of sentence and bail pending appeal

An appeal does not automatically suspend the execution of a sentence.

The BNSS provides a mechanism through which an appellate court may suspend the sentence pending appeal and, where appropriate, release the appellant on bail or personal bond.

The court considers relevant factors, including:

• the nature and seriousness of the offence;
• the sentence imposed;
• the apparent grounds of appeal;
• the likelihood of the appeal being delayed;
• the risk of absconding;
• the possibility of interference with witnesses or evidence; and
• other circumstances relevant to the administration of justice.

The power to suspend a sentence is judicial and discretionary. It should not be confused with an acquittal or a final determination of the appeal.

5.5 Hearing of the appeal

The appellate court considers the grounds of appeal and the material necessary to determine them. The parties may present legal arguments and, where appropriate, address factual questions arising from the record.

The BNSS regulates the summary dismissal of certain appeals and the circumstances in which a full hearing is required. The court must follow the applicable procedural safeguards and give reasons in accordance with the governing legal principles.

Where the accused is in custody, the court must also consider the procedural requirements relating to representation and the accused’s opportunity to participate.

5.6 Powers of the appellate court

The BNSS confers substantial powers on appellate courts. Depending on the nature of the appeal, the court may:

• dismiss the appeal;
• reverse the conviction and acquit or discharge the accused;
• order a retrial where legally justified;
• alter the finding while maintaining the sentence where permitted;
• reduce or enhance a sentence within the applicable legal framework;
• alter the nature of the sentence where authorised;
• make consequential orders concerning custody or release; or
• exercise other statutory powers necessary to dispose of the appeal.

These powers are not unlimited. The appellate court must act within the jurisdiction conferred by law and comply with procedural safeguards, particularly where an enhancement of sentence or other adverse order is contemplated.

6. Further Evidence and the Limits of Appellate Intervention

6.1 Additional evidence before an appellate court

An appeal is ordinarily decided on the record of the proceedings below. Nevertheless, the BNSS permits an appellate court to take additional evidence or direct that additional evidence be taken where the statutory conditions are satisfied.

This power is important where material evidence was unavailable at trial, where a necessary witness could not be examined, or where the appellate court considers further evidence essential to reach a just decision.

The power must be exercised cautiously. An appeal should not routinely become an opportunity for the prosecution or defence to repair weaknesses in its case. The court must consider why the evidence was not produced earlier, whether it is genuinely necessary, and whether the opposing party will have a fair opportunity to challenge it.

6.2 Retrial and remand

An appellate court may order a retrial where a serious procedural defect or other legal failure makes a valid determination impossible. It may also remit a matter for further proceedings where the law permits.

A retrial is not justified merely because the appellate court would have assessed the evidence differently. It is generally reserved for circumstances in which the original proceedings were materially defective or the interests of justice require a fresh determination.

The decision must balance the accused’s right to a fair trial against the public interest in the proper administration of criminal justice. Repeated retrials can themselves become oppressive, particularly where the accused has already spent a substantial period in custody.

6.3 Finality of appellate decisions

The BNSS provides that appellate judgments and orders are generally final, subject to statutory exceptions and the constitutional jurisdiction of the Supreme Court.

Finality is necessary to prevent criminal proceedings from continuing indefinitely. It does not, however, eliminate every form of further judicial scrutiny. Depending on the case, a party may have access to a further statutory appeal, a special leave petition, a review petition, or another remedy recognised by law.

These remedies are governed by different standards and should not be treated as interchangeable.

7. Constitutional Appeals and Review Before the Supreme Court

7.1 Article 134: Criminal appellate jurisdiction

Article 134 of the Constitution provides a direct constitutional route for specified criminal appeals to the Supreme Court.

An appeal lies where a High Court, on appeal, reverses an order of acquittal and sentences the accused to death. It also lies where a High Court withdraws a case from a subordinate court for trial before itself and, after conviction, sentences the accused to death.

The Constitution also permits an appeal where the High Court certifies that the case is a fit one for appeal to the Supreme Court. Parliament may confer further appellate powers on the Supreme Court in criminal matters, subject to constitutional limits.

The provision therefore establishes defined circumstances in which the Supreme Court’s criminal appellate jurisdiction is available without requiring the appellant to rely exclusively on special leave.

7.2 Article 136: Special leave to appeal

Article 136 is one of the most significant constitutional provisions governing appellate supervision in India. It allows the Supreme Court, in its discretion, to grant special leave to appeal from a judgment, decree, determination, sentence, or order passed by a court or tribunal in India.

The provision is deliberately broad, but it does not create an unrestricted right to a second appeal. The Supreme Court has repeatedly treated special leave as an exceptional jurisdiction, to be exercised where intervention is justified by substantial legal error, serious injustice, procedural irregularity, or another compelling circumstance.

In criminal cases, the Court may consider whether the challenged decision reflects a serious miscarriage of justice, a material misapplication of law, an unreasonable evaluation of evidence, or a violation of constitutional protections.

The fact that a party disagrees with the High Court’s conclusion is not, by itself, sufficient to require the Supreme Court to intervene.

7.3 Review under Article 137

Article 137 gives the Supreme Court the power to review its judgments and orders, subject to legislation made by Parliament and rules adopted by the Court.

A review petition is not a further appeal. Its purpose is to correct a recognised category of error, such as an apparent error on the face of the record or another ground permitted by the applicable rules and judicial doctrine.

The Supreme Court’s review jurisdiction is therefore narrow. It does not ordinarily permit a litigant to reopen the entire case simply because the original arguments were unsuccessful.

7.4 Curative petitions

Indian constitutional jurisprudence recognises a further, exceptional remedy known as a curative petition. It developed from the Supreme Court’s inherent powers and was explained in Rupa Ashok Hurra v. Ashok Hurra (2002).

A curative petition is not a routine additional stage of appeal. It is intended to address exceptional circumstances in which a final judgment may have resulted in a fundamental failure of justice, including certain serious violations of natural justice or situations involving a justified apprehension of judicial bias.

The remedy is subject to stringent procedural and substantive conditions. It is therefore not a general means of extending criminal litigation after the ordinary appellate and review processes have concluded.

7.5 The importance of reasoned appellate judgments

Appellate courts must explain the legal and factual basis of their decisions. Reasoned judgments enable the parties to understand the outcome, allow superior courts to exercise any available supervisory jurisdiction, and contribute to the consistency of legal interpretation.

In criminal cases, the requirement is especially significant because appellate decisions may determine whether a person remains imprisoned, is released, faces a retrial, or is subjected to an enhanced sentence.

8. International Criminal Cooperation: Concept and Legal Foundations

8.1 Why domestic criminal jurisdiction is insufficient

A state exercises criminal jurisdiction primarily within the limits recognised by its domestic law and international law. Police officers and courts do not possess an automatic power to conduct searches, arrest persons, compel testimony, or seize property in another sovereign state.

This creates practical difficulties where criminal activity has an international dimension. A fraud may be organised in India, routed through bank accounts in several countries, and completed through a digital platform hosted abroad. A witness may live overseas, while the suspect may relocate to a state that does not automatically enforce Indian arrest warrants.

International judicial cooperation provides legal mechanisms for addressing these difficulties.

It allows states to assist one another while respecting the territorial sovereignty of the requested state. Cooperation is generally based on treaties, multilateral conventions, domestic legislation, reciprocity, and established diplomatic channels.

8.2 Principal forms of cooperation

International criminal cooperation is not a single procedure. It includes several distinct mechanisms:

1. Extradition: surrender of a person by one state to another for prosecution or enforcement of a sentence.
2. Mutual legal assistance: obtaining evidence, documents, testimony, and other investigative assistance from another state.
3. Service of judicial documents: delivering summonses, notices, warrants, and other court processes abroad.
4. Transfer of persons: arranging the temporary movement of persons, including prisoners or witnesses, for criminal proceedings.
5. Asset tracing and restraint: identifying, freezing, attaching, confiscating, or recovering property connected with criminal conduct.
6. Information exchange: sharing relevant law-enforcement information through formal and informal channels.
7. International police cooperation: cooperation through national police authorities and organisations such as Interpol.

These mechanisms are related but not interchangeable. A request for bank records is ordinarily a matter of mutual legal assistance, not extradition. A request to surrender a suspect is an extradition matter, not merely a request for police information.

8.3 Domestic law and international agreements

India’s international cooperation framework draws on several sources:

• the Extradition Act, 1962;
• the BNSS, particularly Chapter VIII;
• applicable bilateral extradition treaties;
• bilateral mutual legal assistance treaties and agreements;
• multilateral conventions containing cooperation obligations;
• domestic legislation implementing international obligations; and
• principles of reciprocity where legally available.

The existence of an international treaty does not mean that foreign authorities can automatically exercise powers in India. The requested action must be implemented through the applicable Indian legal framework and by the competent Indian authorities.

Equally, an Indian court order does not automatically have coercive effect in a foreign country. Recognition, execution, or enforcement abroad depends on the law and international obligations of the state concerned.

9. Extradition Under Indian Law

9.1 Meaning and purpose of extradition

Extradition is the formal process by which one state surrenders a person to another state for prosecution or to serve a sentence imposed following conviction.

The state requesting surrender is commonly described as the requesting state. The state from which surrender is sought is the requested state.

Extradition prevents individuals from using international borders as a means of escaping criminal proceedings. It is particularly important in cases involving organised crime, corruption, terrorism, trafficking, financial offences, and serious offences committed across national boundaries.

Extradition is not simply an administrative act of deportation. It is a legal process governed by domestic legislation, international arrangements, and safeguards protecting the person whose surrender is requested.

9.2 The Extradition Act, 1962

The Extradition Act, 1962, provides the principal statutory framework for extradition in India. It regulates the surrender of fugitive criminals to foreign states and the return to India of persons located abroad.

The Act distinguishes between states with which India has extradition arrangements and states to which the relevant provisions apply through notified orders.

Section 3 authorises the Central Government to extend the application of the Act to specified foreign states by notification. It also addresses the treatment of treaty states and the possibility of recognising certain multilateral conventions as extradition treaties for specified offences.

The statutory framework is therefore not limited to a single universal extradition treaty. The legal basis must be examined in relation to the particular country and offence involved. indiacode.nic.in+2

9.3 Treaties, arrangements, and reciprocity

India has entered into bilateral extradition treaties with a number of states and has also concluded extradition arrangements with certain countries.

Where a bilateral treaty applies, its provisions determine important aspects of the process, including:

• the offences for which extradition may be granted;
• the evidentiary material required;
• the procedure for making requests;
• grounds for refusal;
• provisional arrest;
• the treatment of nationals;
• the principle of speciality; and
• the circumstances in which surrender may be postponed.

Where no bilateral treaty exists, extradition may still be possible under an applicable multilateral convention, where both states are parties and the convention provides a relevant extradition basis. The Extradition Act also permits the Central Government to treat certain conventions as extradition treaties for the offences covered by them.

Reciprocity may be relevant in the absence of a treaty, but it does not create an unrestricted power to surrender a person. The statutory requirements and any applicable international obligations must still be observed.

9.4 The meaning of a fugitive criminal

The Extradition Act uses the concept of a fugitive criminal to identify a person whose surrender may be sought in connection with an extradition offence.

The person may be accused of an offence or may already have been convicted. The distinction matters because the supporting documentation and evidentiary requirements may differ.

A request for a person who has not yet been tried generally concerns surrender for prosecution. A request concerning a convicted person may seek the enforcement of an existing sentence.

Extradition is not restricted to Indian citizens or foreign nationals as a general category. The applicable treaty and domestic law determine whether nationality affects the state’s ability or obligation to surrender a person.

9.5 Extradition offences and double criminality

A central principle in extradition law is double criminality. Broadly, the conduct for which surrender is requested must constitute a criminal offence under the laws of both the requesting and requested states, subject to the wording of the applicable treaty.

The principle focuses on the substance of the conduct rather than requiring identical statutory terminology or identical offence classifications.

For example, an offence described as criminal breach of trust in one jurisdiction may be characterised differently in another. The question is whether the underlying conduct satisfies the relevant requirements of criminality under both legal systems.

The exact treaty language remains decisive. Some treaties use offence lists; others use a minimum penalty threshold or a combination of approaches. The requesting state must therefore establish that the offence falls within the applicable treaty or statutory definition.

9.6 Political offences and other grounds for refusal

Extradition treaties and domestic legislation may recognise grounds on which surrender can be refused. One historically important category concerns political offences.

The political-offence exception is not unlimited. Modern treaties often exclude serious crimes such as terrorism, certain forms of violence, and offences covered by specific international conventions from the protection ordinarily associated with political offences.

Other potential grounds for refusal may include:

• a request made for the purpose of prosecuting or punishing a person on account of race, religion, nationality, or political opinion;
• a risk of discriminatory treatment or persecution;
• a prosecution that would be contrary to fundamental principles of justice;
• a request concerning an offence that is not extraditable under the applicable treaty;
• a prior final judgment concerning the same conduct, where the applicable legal rule recognises that ground;
• expiry of the relevant limitation period, where the treaty or law makes it relevant; or
• a risk of punishment or treatment incompatible with applicable legal obligations.

The precise grounds depend on the Extradition Act, the applicable treaty, and the circumstances of the case. It would be inaccurate to assume that every treaty contains identical exceptions.

9.7 The procedure for extradition from India

Where a foreign state seeks the surrender of a person located in India, the process generally involves the following stages:

First, the foreign state submits a formal request. The request must be supported by the documents required under the applicable treaty and Indian law. These may include an arrest warrant, a statement of the alleged facts, the relevant legal provisions, identifying information, and evidence or other material specified by the treaty.

Second, the Central Government examines the request. The Ministry of External Affairs plays the central role in extradition matters. The competent division processes requests and coordinates the relevant legal and diplomatic steps.

Third, the person may be arrested under the applicable legal procedure. The Extradition Act provides for warrants and related procedures, including provisional arrest in circumstances authorised by law.

Fourth, a magistrate conducts the statutory inquiry. The inquiry examines whether the legal requirements for extradition are satisfied. It is not ordinarily a full trial of the foreign criminal charge.

Fifth, the magistrate submits the appropriate report or decision under the Act. The Central Government then considers the matter in accordance with the statutory framework and applicable treaty obligations.

Finally, the Central Government decides whether surrender may be ordered. If the legal requirements are met and no applicable ground prevents surrender, the person may be surrendered in accordance with the law.

The extradition process is therefore a combination of judicial examination and executive decision-making. The precise division of responsibilities depends on the applicable statutory route. indiacode.nic.in+1

9.8 Extradition from India to a foreign state

India may also request the surrender of a person located abroad.

Such a request ordinarily originates with the investigating or prosecuting authority handling the case. The relevant agency prepares the extradition dossier, which is processed through the competent Indian authorities and transmitted to the foreign state.

The requesting state must satisfy the requirements of the receiving state’s law and the applicable treaty. An Indian arrest warrant, by itself, does not authorise Indian police officers to arrest the person in foreign territory.

The foreign state decides whether the request meets its legal requirements. Its courts or other competent authorities may examine the request, and its executive authorities may have a further role depending on its domestic system.

The Ministry of External Affairs identifies itself as the Central Authority for extradition matters in India, with the Consular, Passport and Visa Division handling the relevant process. Its published guidance explains the submission of extradition dossiers and the role of law-enforcement agencies in initiating requests. mea.gov.in+1

9.9 Provisional arrest

In urgent cases, a requesting state may seek the provisional arrest of a person before the complete extradition dossier is submitted.

This mechanism is intended to prevent flight while the formal request is being prepared or transmitted. It is generally subject to strict time limits and procedural conditions under the relevant treaty and domestic law.

Provisional arrest is not itself a final determination that extradition should be granted. The requesting state must still provide the required formal documentation within the applicable period. If it fails to do so, the person may become entitled to release under the relevant legal framework.

9.10 The principle of speciality

The principle of speciality limits the offences for which an extradited person may be prosecuted or punished after surrender.

In general, a person surrendered for a specified offence should not be prosecuted for an unrelated offence committed before surrender unless the applicable treaty or law permits it, or the requested state consents.

The principle protects the integrity of the extradition process. A state should not obtain surrender on one stated basis and then use the person’s presence to pursue materially different charges outside the agreed conditions.

The precise scope of speciality, including exceptions and procedures for obtaining consent, depends on the relevant treaty and domestic law.

9.11 The rule against onward surrender

Extradition arrangements may also restrict the transfer of an extradited person to a third state without the consent of the state that originally surrendered that person.

This protection is related to speciality. It prevents a requesting state from using one extradition arrangement as a route to deliver the person to another jurisdiction without observing the conditions of the original surrender.

9.12 Nationality and extradition

Some states restrict or prohibit the extradition of their own nationals. Other states permit extradition regardless of nationality, subject to treaty and constitutional safeguards.

The legal position must be assessed under the applicable treaty and the domestic law of the requested state. It is not accurate to assume that Indian citizenship automatically prevents extradition or that foreign nationality automatically guarantees surrender.

Where a state refuses to extradite its national, the applicable treaty may provide for the possibility of domestic prosecution instead. Such an obligation is not automatic in every case and depends on the relevant legal instruments and jurisdictional rules.

9.13 Human rights and fair-trial considerations

Extradition must be considered consistently with applicable constitutional protections and international obligations.

The requested state may need to consider whether surrender would expose the person to a real risk of torture, inhuman treatment, or another serious violation of fundamental rights. The death penalty may also raise significant questions where the requested state has abolished it or where the applicable treaty requires assurances.

Fair-trial concerns may become relevant where the person faces a real risk of proceedings that fundamentally violate recognised standards of justice. The assessment is fact-specific and depends on the legal obligations binding on the requested state.

Assurances from the requesting state may be relevant in appropriate cases, but their adequacy depends on their specificity, reliability, enforceability, and the circumstances in which they are given.

9.14 Extradition and deportation are different

Extradition must be distinguished from deportation and immigration removal.

Extradition is a formal surrender process undertaken for criminal prosecution or enforcement of a sentence. Deportation generally concerns the removal of a person under immigration or nationality law, for example because the person has violated immigration conditions or is not entitled to remain in the territory.

A state cannot necessarily avoid extradition safeguards simply by describing a transfer as deportation. The legal character of the action, its purpose, and the protections applicable to the person must be considered.

10. Mutual Legal Assistance in Criminal Matters

10.1 Meaning and purpose

Mutual legal assistance, commonly abbreviated as MLA, is a formal system through which one state requests another state to obtain evidence or undertake specified legal measures for use in criminal proceedings.

It is particularly important where evidence is located outside the territorial jurisdiction of the investigating state.

Unlike extradition, MLA does not ordinarily require the surrender of the accused person. It may instead involve the examination of witnesses, production of documents, obtaining bank records, service of judicial processes, search and seizure, or restraint of property.

The purpose is to enable criminal investigations and prosecutions to proceed effectively while ensuring that evidence is obtained through legally recognised procedures.

10.2 India’s central authority for mutual legal assistance

The Ministry of Home Affairs is India’s nodal ministry and Central Authority for mutual legal assistance in criminal matters.

Its Internal Security-II Division handles the subject. The Ministry receives, examines, and processes requests for assistance from foreign states and requests made by Indian authorities to other jurisdictions. The Ministry of External Affairs may also be involved where requests are transmitted through diplomatic channels.

The allocation of responsibility is important. Extradition and mutual legal assistance are related areas of international cooperation, but they are not handled through an identical institutional process. The MEA identifies itself as the central authority for extradition, while the MHA is the central authority for criminal MLA. mea.gov.in+2

10.3 Treaties and reciprocity

India provides mutual legal assistance through several legal bases:

• bilateral mutual legal assistance treaties;
• bilateral agreements;
• multilateral treaties and conventions;
• applicable international obligations; and
• reciprocity, where legally available.

A bilateral MLAT generally identifies the forms of assistance available, the competent authorities, the procedures for transmitting requests, the grounds for refusal, and any conditions governing the use of evidence.

The precise terms vary between agreements. A request should therefore be prepared with reference to the treaty applicable to the particular state rather than relying on a generic template.

India’s Ministry of Home Affairs publishes information about its international cooperation arrangements and identifies the role of MLATs in investigation, prosecution, prevention of crime, service of judicial documents, execution of warrants and judicial commissions, and tracing or confiscating proceeds and instruments of crime. Ministry of Home Affairs+1

10.4 Types of assistance available

Depending on the treaty and domestic law, mutual legal assistance may include:

• taking statements from witnesses;
• examining witnesses before a competent judicial authority;
• obtaining documentary evidence;
• producing business and financial records;
• obtaining bank information;
• serving summonses and notices;
• executing search warrants;
• obtaining and preserving electronic evidence;
• locating persons;
• identifying and tracing criminal proceeds;
• freezing, attaching, or confiscating property;
• facilitating the temporary transfer of persons; and
• providing authenticated records or certified copies.

The requested state generally executes the request according to its own legal procedures, while taking account of any permissible special requirements specified by the requesting state.

A requesting authority cannot simply demand that foreign officials exercise powers unavailable under the requested state’s law.

10.5 The difference between formal MLA and informal information exchange

Not every exchange of information between law-enforcement agencies constitutes mutual legal assistance.

Police authorities may exchange intelligence or operational information through established channels. Such exchanges can assist investigations, identify suspects, or indicate where evidence may be located.

However, information obtained informally may not be sufficient for use as evidence in court. Where coercive measures are required, or where formal evidentiary material must be collected and authenticated, the appropriate legal assistance procedure may be necessary.

The distinction is especially important in cases involving bank secrecy, confidential business records, communications data, electronic devices, and testimony from witnesses abroad.

11. Mutual Legal Assistance Under Chapter VIII of the BNSS

11.1 The statutory framework

Chapter VIII of the BNSS, comprising Sections 111–124, establishes the Indian procedural framework for reciprocal assistance in specified matters and for attachment and forfeiture of property.

It replaces and develops the corresponding framework previously contained in the Code of Criminal Procedure, 1973. The chapter is particularly important because it provides domestic legal authority for cooperation with foreign states, rather than leaving international assistance entirely to treaty arrangements.

The provisions address requests made by Indian authorities to foreign jurisdictions, requests received from abroad, transfer of persons, and cooperation relating to criminal property. indiacode.nic.in+1

11.2 Section 110: Reciprocal arrangements regarding processes

Section 110 concerns reciprocal arrangements for the service or execution of certain legal processes in foreign countries and in India.

It enables the Central Government to make arrangements with foreign governments concerning the service of summonses, warrants, and other judicial processes. The practical operation of the provision depends on the relevant arrangement and the procedures specified by the Central Government.

This mechanism is important where an Indian court needs to serve a person living abroad or where a foreign judicial process must be served in India.

Service of a summons is not the same as extradition. A summons requires a person to appear or respond in accordance with the applicable legal procedure. A request to arrest and surrender a person for prosecution must follow the extradition framework where that is the legal purpose.

11.3 Section 111: Definitions

Section 111 defines key expressions used in Chapter VIII, including concepts relating to contracting states, corresponding laws, criminal property, and other matters necessary for the operation of the chapter.

These definitions establish the scope of the reciprocal cooperation provisions. Their importance lies in connecting Indian domestic criminal procedure with the legal systems of states that participate in relevant arrangements.

11.4 Section 112: Requests by Indian courts for foreign investigation

Section 112 provides for a letter of request to a competent authority in a country or place outside India where evidence may be available during an investigation.

An investigating officer, or an officer superior in rank, may apply for such a request. A criminal court may then issue a letter to a competent foreign court or authority seeking the examination of a person believed to know relevant facts, the recording of that person’s statement, or the production of documents or other things connected with the case.

The evidence collected abroad is transmitted in the manner specified by the Central Government. Statements, documents, and things received through the statutory process are treated as evidence collected during the investigation under the BNSS.

This provision is significant because it gives Indian criminal courts a formal route to obtain foreign evidence without assuming that Indian investigators can exercise coercive powers in another country. IndiaCode+1

11.5 Section 113: Requests received from foreign states

Section 113 provides the corresponding mechanism for requests received from a foreign court or competent authority seeking evidence in India.

Upon receiving a qualifying letter of request, the Central Government may forward it to a Chief Judicial Magistrate or another Judicial Magistrate appointed for that purpose. The Magistrate may summon the relevant person, record a statement, or require the production of documents or other things.

Alternatively, the Central Government may send the request to a police officer for investigation. The officer then investigates in the manner prescribed by the provision, as if the offence had been committed in India.

The evidence collected is forwarded through the Central Government to the requesting foreign authority.

The provision therefore enables India to assist foreign criminal proceedings while retaining control over the manner in which evidence is obtained within Indian territory. IndiaCode+1

11.6 Section 114: Assistance in securing the transfer of persons

Section 114 addresses assistance in securing the transfer of persons in connection with criminal proceedings involving contracting states.

It covers circumstances in which an Indian court seeks the execution abroad of a warrant or other process requiring a person’s attendance or the production of a document or thing. It also provides for the execution in India of certain warrants received from a contracting state.

The section further addresses the temporary transfer of persons who are prisoners in one state but whose attendance is required in another jurisdiction.

Where a prisoner is transferred, the conditions attached to the transfer must be respected. The person must be kept in the custody required by the applicable arrangement and must not be treated as though the transfer automatically extinguishes the original sentence or detention status.

Temporary transfer is conceptually different from extradition. Its purpose is to secure participation in a specified proceeding or investigative process, not necessarily to surrender the person permanently to another state. indiacode.nic.in+1

11.7 Sections 115–122: Attachment and forfeiture of property

Chapter VIII also deals with property connected with criminal activity.

Sections 115–122 establish a framework for assistance relating to orders of attachment and forfeiture, identifying unlawfully acquired property, seizure or attachment, management of seized property, notice of forfeiture, and related matters.

These provisions are particularly relevant to transnational financial crime. Criminal proceeds may be transferred through several jurisdictions, converted into real estate or other assets, or held through corporate structures and intermediaries.

International cooperation allows authorities to trace and restrain such property where the applicable law and arrangements permit.

The legal process must nevertheless distinguish between property that is genuinely connected with criminal conduct and property belonging to innocent third parties. Attachment and forfeiture must be supported by the applicable statutory requirements and procedural safeguards.

11.8 Section 123: Procedure concerning letters of request

Section 123 provides for procedural matters relating to letters of request under the chapter.

The provision supports the formal transmission and handling of requests and the evidence obtained through them. The purpose is to ensure that cooperation is carried out through recognised channels rather than through informal or unauthorised demands.

The precise requirements must be read together with the applicable treaty, Central Government directions, and relevant procedural rules.

11.9 Section 124: Application of the chapter

Section 124 addresses the application of Chapter VIII. It must be read with the definitions and reciprocal arrangements established by the preceding provisions.

The chapter is not a general licence for Indian authorities to conduct investigations abroad. Its operation depends on the statutory framework, the relevant foreign jurisdiction, and the applicable reciprocal or treaty arrangements.

12. Evidence Obtained Abroad and Its Use in Indian Criminal Proceedings

12.1 The importance of lawful collection

Evidence obtained abroad must be collected through a process that is legally recognised and sufficiently reliable for use in criminal proceedings.

A document sent informally by a foreign police agency may be useful as an investigative lead, but it may not automatically satisfy the requirements for admissibility or proof in an Indian court.

The manner of collection, authentication, certification, transmission, and preservation can all affect the evidentiary value of foreign material.

12.2 The Bharatiya Sakshya Adhiniyam, 2023

The Bharatiya Sakshya Adhiniyam, 2023 (BSA), governs the law of evidence in India and operates alongside the BNSS.

The BSA addresses documentary evidence, electronic and digital records, proof of documents, and the admissibility of material obtained through legally recognised procedures.

Where evidence is collected abroad, the court may need to examine whether the material satisfies the relevant evidentiary requirements, whether its authenticity has been established, and whether the accused has had a fair opportunity to challenge it.

The fact that a document was transmitted under an MLA arrangement does not necessarily resolve every question of admissibility. The receiving court must still apply the relevant evidentiary rules.

12.3 Authentication and certification

Foreign documents may require authentication or certification in accordance with the applicable treaty, domestic law, or procedural requirements.

The relevant questions may include:

• whether the document is what it purports to be;
• whether the issuing authority is competent;
• whether the signature, seal, or certification is genuine;
• whether the document has been translated accurately where necessary;
• whether the chain of custody has been preserved; and
• whether the material was obtained in a manner compatible with the applicable legal framework.

These issues are particularly important for financial records, corporate documents, official registers, medical records, forensic reports, and digital communications.

12.4 Digital evidence and cross-border investigations

Digital evidence creates particular difficulties because data may be stored in a jurisdiction different from the location of the user, the service provider, or the alleged offence.

Investigators may need information held by foreign cloud-service providers, social media companies, financial technology platforms, or telecommunications operators.

A request may concern subscriber information, account records, transaction histories, stored communications, or other electronic material. The availability of the data and the procedure for obtaining it depend on the law of the country where the provider or data is located, the applicable treaty, and any relevant international or domestic rules.

The requesting state must also consider preservation. Electronic evidence can be altered, deleted, or lost. Timely preservation requests may therefore be necessary while formal legal assistance is being prepared.

12.5 Chain of custody and reliability

The chain of custody records how evidence was collected, handled, stored, transferred, and examined.

In cross-border cases, this may involve several authorities, laboratories, service providers, and courts. Each transfer creates a need for adequate documentation.

A gap in the chain of custody does not automatically make every item inadmissible, but it may affect authenticity, reliability, or evidentiary weight. The court must assess the circumstances and apply the relevant rules of evidence.

12.6 The accused person’s right to challenge foreign evidence

Evidence obtained abroad cannot be treated as immune from challenge merely because it was collected under an international cooperation arrangement.

The accused must have a fair opportunity to contest material evidence in accordance with the applicable procedural and evidentiary rules. This may involve questioning the reliability of a foreign witness’s statement, challenging the authenticity of documents, disputing the interpretation of digital material, or raising objections concerning the manner in which evidence was obtained.

The court must balance the practical realities of international evidence gathering with the requirements of a fair criminal trial.

13. Interpol and International Police Cooperation

13.1 India’s participation in Interpol

The International Criminal Police Organization, commonly known as Interpol, facilitates cooperation among national law-enforcement authorities.

India participates in this system through its National Central Bureau, which operates through the Central Bureau of Investigation (CBI). The National Central Bureau acts as a national point of contact for communications and cooperation with Interpol and other member states.

Interpol facilitates information exchange, the circulation of notices, and cooperation in locating persons or identifying cross-border criminal activity.

It does not operate as a supranational police force. Its notices do not independently confer powers of arrest on Indian or foreign police officers.

13.2 Red Notices

A Red Notice is a request to law-enforcement authorities worldwide to locate a person and, where appropriate, provisionally arrest that person pending extradition, surrender, or similar legal action.

It is based on a valid national arrest warrant or judicial decision and is circulated through Interpol’s systems.

A Red Notice is not an international arrest warrant. Whether the person may be arrested depends on the domestic law of the country in which the person is located and any applicable treaty or extradition arrangement.

The requested state retains responsibility for deciding whether arrest and surrender are legally permissible.

13.3 Other Interpol notices

Interpol uses different notices for different purposes. These include notices concerning missing persons, unidentified bodies, requests for information, warnings about criminal activity, and other forms of police cooperation.

The legal effect of a notice depends on its category and the domestic law of the receiving state. A notice should not be confused with a court order that automatically authorises coercive measures.

13.4 Interpol and extradition

Interpol can assist in locating a person whose extradition is sought, but the extradition process remains governed by national law and international arrangements.

A Red Notice may alert authorities to a person’s location or facilitate provisional action. It does not replace the formal extradition dossier, the judicial inquiry, or the decision-making process required by the Extradition Act and the relevant treaty.

This distinction protects the legal character of extradition and prevents police cooperation mechanisms from being mistaken for independent judicial authority.

14. International Cooperation in Financial and Organised Crime Cases

14.1 The international movement of criminal proceeds

Many serious offences involve financial transactions across national borders. Fraud, corruption, cybercrime, drug trafficking, trafficking in persons, and organised crime may generate proceeds that are transferred through banks, companies, digital platforms, or intermediaries in several jurisdictions.

Investigators may need to identify beneficial ownership, trace transactions, obtain account records, freeze assets, and secure evidence from foreign financial institutions.

The domestic powers of an Indian investigating agency cannot simply be exercised in another country. Formal cooperation is therefore essential.

14.2 Asset tracing and freezing

Asset tracing seeks to identify property that may be connected with criminal activity. Freezing or attachment prevents the property from being transferred, concealed, or dissipated while proceedings are pending.

A request for assistance may seek:

• identification of bank accounts;
• information about account holders and beneficial owners;
• transaction records;
• details of corporate ownership;
• preservation of relevant financial records;
• provisional restraint of property; or
• enforcement of a final confiscation or forfeiture order.

The legal basis may be found in an MLAT, a multilateral convention, the BNSS, or another applicable statute.

14.3 The distinction between attachment and confiscation

Attachment or freezing is generally a provisional measure. It restricts dealings with property while the legal process continues.

Confiscation or forfeiture is a more definitive legal consequence involving the transfer or loss of rights in property under the applicable law.

The two stages should not be confused. A foreign state may agree to freeze property temporarily without agreeing that the property should ultimately be confiscated. Final confiscation may require a separate judicial decision and compliance with the relevant domestic procedures.

14.4 Cooperation in corruption and money-laundering investigations

International assistance is particularly important in corruption and money-laundering cases because the proceeds of unlawful activity may be moved through several financial systems.

Indian authorities may need foreign evidence to establish the origin of funds, identify the individuals controlling accounts, prove the movement of money, or connect a foreign asset to an offence investigated in India.

Such cooperation may involve the BNSS, the Prevention of Money-laundering Act, 2002, the Prevention of Corruption Act, 1988, and applicable international arrangements.

Each statute has its own legal requirements. The availability of MLA does not automatically satisfy the substantive requirements for attachment, prosecution, or confiscation.

15. Extradition, MLA, and the Protection of Fundamental Rights

15.1 The constitutional position

International criminal cooperation must operate consistently with India’s constitutional framework.

Article 21 protects life and personal liberty and requires that deprivation of liberty follow a procedure established by law that satisfies constitutional standards of fairness. Article 14 prohibits arbitrary state action. Article 22 provides specific protections concerning arrest and detention.

These guarantees remain relevant where Indian authorities arrest a person pursuant to an extradition request, execute a foreign judicial process, or obtain evidence for use in a criminal proceeding.

The Constitution does not make international cooperation impossible. Rather, it requires that cooperation be conducted through lawful procedures and subject to applicable safeguards.

15.2 Procedural fairness in extradition

A person facing extradition must be dealt with according to the Extradition Act, the applicable treaty, and relevant constitutional principles.

The person may raise objections recognised by the applicable legal framework, including questions about identity, the legal basis of the request, whether the alleged conduct is extraditable, and whether a ground for refusal applies.

The extradition inquiry is not ordinarily a full determination of guilt or innocence. Its purpose is to determine whether the statutory and treaty requirements for surrender are satisfied.

15.3 Protection against torture and inhuman treatment

A state considering surrender must take seriously any substantiated risk that the person may face torture or treatment contrary to applicable human rights obligations.

The assessment is not resolved merely by the seriousness of the alleged offence. The requesting state may be required to provide assurances, and the requested state must evaluate whether those assurances adequately address the identified risk.

The legal standard depends on the obligations binding on the state concerned and the evidence presented.

15.4 Fair-trial concerns

Extradition may raise questions about the fairness of the anticipated proceedings. Relevant concerns can include denial of legal representation, discriminatory prosecution, politically motivated proceedings, or a real risk that the person will be unable to receive a fair hearing.

Not every procedural difference between two legal systems justifies refusal. The issue is whether the circumstances reach the threshold recognised by the applicable treaty, domestic law, or human rights obligations.

15.5 Protection of privacy and confidential information

Mutual legal assistance may involve highly sensitive personal and commercial information.

Requests for bank records, communications, medical documents, and digital data should be legally authorised and sufficiently specific. The use of information may be limited by treaty conditions, domestic privacy law, confidentiality obligations, or restrictions on onward disclosure.

The requesting authority should not assume that material obtained for one investigation may be used for any unrelated purpose. The terms of the treaty and the applicable legal framework may restrict subsequent use.

16. International Judicial Cooperation and Indian Sovereignty

16.1 Territorial sovereignty

International cooperation rests on the principle that states exercise public authority within their own territories.

Indian police officers cannot ordinarily conduct searches or arrests in a foreign state simply because an Indian court has issued a warrant. Likewise, foreign officers cannot exercise coercive investigative powers in India without an appropriate legal basis and compliance with Indian law.

This principle protects the sovereign authority of each state and prevents unilateral enforcement action across borders.

16.2 Execution through the requested state’s authorities

A foreign request is generally implemented by the competent authorities of the requested state.

For example, where India seeks a witness statement from another country, the request is transmitted through the prescribed channel. The foreign authority then arranges the examination in accordance with its own legal system and the applicable treaty.

The same principle applies when India receives a foreign request. Indian authorities execute it under Indian law, including the BNSS and any other applicable legislation.

16.3 Reciprocity and international confidence

Reciprocity can be important where a formal treaty does not govern a particular form of assistance. A state may provide assistance based on an assurance that comparable cooperation will be considered in return.

However, reciprocity is not a substitute for domestic legal authority. Indian officials must still act within their statutory powers, and foreign requests must be processed through recognised channels.

Effective cooperation also depends on confidence that evidence will be used for the stated purpose, confidential information will be protected, and legal safeguards will be respected.

17. Practical Challenges in International Criminal Cooperation

17.1 Differences between legal systems

Countries differ in their rules of evidence, criminal procedure, judicial authority, privacy, data protection, and police powers.

A request that is legally straightforward in one jurisdiction may be difficult to execute in another. For example, a foreign state may require judicial authorisation before producing bank records, while another may permit administrative disclosure in defined circumstances.

The requesting authority must understand these differences and prepare a request that can be executed lawfully.

17.2 Delay and administrative complexity

International requests often involve several institutions, including investigating agencies, ministries, central authorities, diplomatic missions, courts, and foreign law-enforcement bodies.

Translation, authentication, legal review, and procedural requirements can extend the time needed to execute a request.

Delay is especially problematic where evidence may be deleted, assets may be transferred, or a suspect may move to another country. Early coordination and careful preparation are therefore essential.

17.3 Differences in evidentiary standards

The requesting and requested states may apply different standards to the collection and presentation of evidence.

A foreign authority may require a detailed explanation of the relevance of each document sought, while the requesting state may be accustomed to broader investigative powers.

The requesting authority must ensure that the evidence collected can satisfy the requirements of the eventual trial. Otherwise, the material may prove useful for intelligence purposes but insufficient for judicial proof.

17.4 Digital evidence and jurisdictional uncertainty

Digital investigations create additional complexity because data may be distributed across several countries and controlled by companies subject to multiple legal systems.

The location of a server does not always determine which authority has legal power to obtain the data. The relevant questions may include the provider’s place of establishment, the nature of the information, the applicable privacy rules, and any treaty or statutory mechanism.

The development of international standards for electronic evidence is therefore an important part of contemporary criminal cooperation.

17.5 Protection of third-party rights

International requests may affect persons who are not accused of any offence. A bank account may belong to a family member, a company may hold property for several investors, or a digital device may contain information relating to unrelated individuals.

The legal process must take account of legitimate third-party interests, confidentiality, privilege, and proportionality. International cooperation should not become a means of obtaining information or restraining property without a proper legal basis.

17.6 Political and diplomatic considerations

Extradition and mutual legal assistance can involve sensitive diplomatic relations. Disagreements may arise over the definition of offences, the treatment of nationals, the reliability of assurances, or the political context of a prosecution.

Nevertheless, decisions must be grounded in the applicable legal framework. Diplomatic considerations cannot lawfully replace the statutory requirements governing an extradition or MLA request.

18. Important Judicial Principles and Decisions

Indian courts have developed principles concerning appellate intervention, acquittals, constitutional review, and international cooperation. The following decisions illustrate important aspects of the legal framework.

18.1 Chandrappa v. State of Karnataka (2007)

The Supreme Court considered the powers of an appellate court hearing an appeal against acquittal. It explained that an appellate court has full power to review, reappreciate, and reconsider the evidence on which the acquittal is based.

At the same time, the Court emphasised the importance of the presumption of innocence and the caution required before reversing an acquittal. Where two reasonable views are possible, the view favourable to the accused should ordinarily be respected.

The decision remains an important reference for understanding appellate review of acquittals.

18.2 Rama v. State of Rajasthan (2002)

The Supreme Court discussed the principles governing appellate consideration of criminal evidence and the circumstances in which an appellate court may interfere with findings of fact.

The decision illustrates that appellate jurisdiction is not confined to questions of law, although the court must exercise its powers in accordance with established principles and the evidentiary record.

18.3 Rupa Ashok Hurra v. Ashok Hurra (2002)

This decision recognised the exceptional curative jurisdiction of the Supreme Court after dismissal of a review petition.

The Court explained that finality of judgments is fundamental, but exceptional circumstances may require intervention to prevent a gross miscarriage of justice. The decision is the foundation of the curative petition procedure.

18.4 Pritam Singh v. The State (1950)

An early and important decision on Article 136, Pritam Singh explained the exceptional nature of the Supreme Court’s special leave jurisdiction.

The Court indicated that special leave is not intended to operate as an ordinary appeal available to every unsuccessful litigant. It is a discretionary jurisdiction reserved for cases requiring intervention in the interests of justice.

18.5 Ranjitsing Brahmajeetsing Sharma v. State of Maharashtra (2005)

The Supreme Court examined the relationship between statutory restrictions and the constitutional jurisdiction of the courts in criminal matters.

The decision is relevant to the broader principle that special statutory regimes may impose particular conditions on judicial relief, while constitutional remedies remain governed by their own legal framework.

18.6 Daya Singh v. State of Haryana (2001)

The Supreme Court discussed the principles governing appellate interference with an acquittal and the need to examine the evidence carefully before reversing the trial court’s conclusion.

The case reinforces the distinction between the power to reappreciate evidence and the restraint appropriate where an acquittal is reasonably supported by the record.

18.7 Sushil Suri v. Central Bureau of Investigation (2011)

The Supreme Court considered issues arising from an investigation involving financial transactions and the legal treatment of complex economic conduct.

The decision is relevant to the wider context of financial crime investigations, although it should not be treated as a general ruling on extradition or MLA procedure.

18.8 State of Madhya Pradesh v. Balram Mihani (2010)

The Supreme Court considered provisions of the former Code of Criminal Procedure concerning attachment and forfeiture in cases involving international criminal cooperation.

The judgment is relevant to understanding the purpose and scope of the reciprocal assistance framework that preceded Chapter VIII of the BNSS. Its interpretation may assist in understanding provisions carried forward into the current procedural law, while the text of the BNSS remains controlling for proceedings governed by the new legislation. IndiaCode+1

18.9 Rupa Ashok Hurra and the finality of criminal proceedings

Although the curative jurisdiction is exceptional, the decision illustrates a fundamental tension in criminal procedure: the need to bring litigation to an end and the need to prevent a grave miscarriage of justice.

The same tension appears in appellate review more generally. Criminal judgments must become final at some point, but the legal system must preserve carefully controlled mechanisms for correcting serious errors.

19. The Relationship Between Appeals, Extradition, and Mutual Legal Assistance

The three mechanisms examined in this article perform different functions, but they may arise within the same criminal case.

Consider a hypothetical situation in which an individual is suspected of organising a financial fraud from India. The alleged proceeds are transferred through accounts in two foreign jurisdictions, while the suspect relocates abroad.

The investigation may require several forms of cooperation:

1. Indian investigators may seek foreign bank records through a letter of request under Section 112 of the BNSS and the applicable MLAT.
2. Foreign authorities may assist in identifying the beneficial owners of accounts and preserving relevant records.
3. If the suspect is located abroad, India may submit an extradition request under the Extradition Act and the applicable treaty.
4. Once surrendered, the accused may be prosecuted in India, subject to the principle of speciality and the conditions of surrender.
5. If convicted, the accused may challenge the conviction or sentence through the appellate structure established by the BNSS.
6. The appellate court may examine the admissibility, authenticity, and reliability of evidence obtained abroad.

This example demonstrates why international cooperation and appellate review must be understood as connected parts of criminal justice. International assistance helps establish the facts and secure the presence of persons or evidence. Appellate review ensures that the resulting domestic proceedings comply with the law.

Neither process should be treated as a substitute for the other. International cooperation cannot cure an unfair trial, and appellate jurisdiction cannot itself compel a foreign state to surrender a person or produce evidence.

20. The Future of Criminal Appeals and International Cooperation in India

The increasing internationalisation of crime is likely to place further demands on India’s criminal justice system.

Financial crime, cybercrime, digital fraud, trafficking, terrorism, and organised criminal networks often operate across borders. Their investigation requires timely access to electronic records, financial information, witnesses, and property located in other jurisdictions.

At the same time, the expanding use of digital evidence increases the importance of authentication, data integrity, privacy, and the chain of custody. Courts will increasingly need to examine whether evidence obtained through foreign cooperation satisfies Indian evidentiary standards and whether the accused has had a fair opportunity to challenge it.

The BNSS provides a statutory framework for reciprocal assistance, while the Extradition Act and international agreements establish mechanisms for surrendering persons. The effectiveness of these instruments will depend on institutional coordination, the quality of requests, the capacity of investigating agencies, and the willingness of partner states to cooperate.

Appellate courts will continue to play an essential role in ensuring that these processes remain subject to the rule of law. Their task is not simply to correct errors in individual cases. Through reasoned judgments, they also clarify the legal limits of state power and the safeguards that must accompany criminal proceedings.

Conclusion

Criminal appeals and international judicial cooperation are essential to the legitimacy and effectiveness of India’s criminal justice system. Appellate review provides a structured means of correcting legal and factual errors, protecting procedural fairness, and maintaining consistency in the interpretation of criminal law. The BNSS establishes the principal statutory framework, while the Constitution provides additional avenues of review through the High Courts and the Supreme Court.

Extradition and mutual legal assistance address a different problem: the territorial limitations of domestic criminal jurisdiction. The Extradition Act, 1962, allows India to seek the surrender of persons located abroad and to consider requests made by foreign states. Chapter VIII of the BNSS provides mechanisms for obtaining evidence, serving judicial processes, transferring persons, and cooperating in the tracing and restraint of criminal property.

These procedures must operate within the rule of law. International cooperation cannot justify arbitrary arrest, disregard of sovereignty, or the denial of fundamental rights. Evidence obtained abroad must remain subject to applicable evidentiary rules, and persons facing extradition must receive the protections required by domestic law and relevant international obligations.

The central principle is that criminal justice must be both effective and lawful. A state must be capable of investigating and prosecuting offences that cross borders, but the pursuit of criminal accountability cannot displace fair procedure, judicial independence, or constitutional protection. India’s appellate and international cooperation frameworks seek to reconcile these requirements.

Frequently Asked Questions

1. What law governs criminal appeals in India?

The principal legislation is the Bharatiya Nagarik Suraksha Sanhita, 2023. Its Chapter XXXI, Sections 413–435, regulates ordinary criminal appeals. The Constitution and special statutes provide additional appellate remedies in specified circumstances.

2. Can every criminal conviction be appealed?

No. The right of appeal is generally created by statute. The BNSS identifies the convictions and orders that may be appealed and also provides restrictions in certain cases, including specified convictions following a guilty plea and certain petty cases.

3. Can a victim appeal against an acquittal?

Yes. Section 413 of the BNSS recognises a victim’s right to appeal against an order acquitting the accused, convicting the accused for a lesser offence, or imposing inadequate compensation. The appeal lies to the court to which an appeal against the conviction would ordinarily lie.

4. Can the prosecution appeal against an acquittal?

Yes, in circumstances governed by Section 419 of the BNSS. The statutory procedure and any applicable requirements concerning leave or authorisation must be followed.

5. Can an appellate court increase a criminal sentence?

An appellate court may enhance a sentence where the applicable statutory provisions confer that power. The court must follow the required procedure and provide the affected person with an opportunity to address the proposed enhancement.

6. Does filing an appeal automatically release a convicted person from prison?

No. An appeal does not automatically suspend the sentence. The appellate court may suspend execution of the sentence and grant bail where the applicable statutory requirements and circumstances justify doing so.

7. What is the difference between an appeal and a revision?

An appeal is a statutory mechanism for challenging a decision before a higher court. Revision is a supervisory jurisdiction concerned with the legality, correctness, propriety, or regularity of specified proceedings and orders. Revision is not generally a replacement for an available appeal.

8. What is special leave to appeal under Article 136?

Article 136 gives the Supreme Court discretionary power to permit an appeal from a judgment, determination, sentence, or order of a court or tribunal in India. It is an exceptional constitutional remedy rather than an ordinary right of appeal.

9. What is a curative petition?

A curative petition is an exceptional procedure recognised by the Supreme Court to address certain fundamental failures of justice after the ordinary appeal and review processes have been exhausted. It is subject to stringent conditions.

10. What is extradition?

Extradition is the formal surrender of a person by one state to another for criminal prosecution or enforcement of a sentence. It is governed by the domestic law of the requested state and any applicable international arrangement.

11. Which law governs extradition in India?

The principal statute is the Extradition Act, 1962. It operates together with applicable bilateral treaties, extradition arrangements, and multilateral conventions.

12. Can India extradite a person if there is no bilateral extradition treaty?

Potentially, yes. An applicable multilateral convention may provide a legal basis for extradition where both states are parties and the relevant offence is covered. The Extradition Act also permits certain conventions to be treated as extradition treaties for specified offences. The existence of a legal basis and the applicable statutory requirements must be examined in each case.

13. What is double criminality?

Double criminality is the principle that the conduct underlying an extradition request must generally constitute a criminal offence under both the requesting and requested states’ laws. The exact formulation depends on the applicable treaty and may focus on the conduct rather than identical offence names.

14. Can a person be extradited for a political offence?

The answer depends on the applicable treaty and statutory framework. Some extradition arrangements recognise a political-offence exception, while others exclude serious offences, including specified terrorist offences, from its scope.

15. What is the principle of speciality?

The principle of speciality generally prevents a requesting state from prosecuting an extradited person for an unrelated offence committed before surrender unless the applicable treaty or law permits it or the requested state gives consent.

16. Is extradition the same as deportation?

No. Extradition is a formal criminal surrender procedure. Deportation is generally an immigration-law measure. The legal basis, purpose, and safeguards are different.

17. What is mutual legal assistance?

Mutual legal assistance is a formal process through which one state obtains evidence or other legal assistance from another state for criminal investigations or proceedings. It may involve witness statements, financial records, documents, searches, service of judicial processes, or asset tracing.

18. Which Indian authority handles mutual legal assistance requests?

The Ministry of Home Affairs is India’s nodal ministry and Central Authority for mutual legal assistance in criminal matters. Its Internal Security-II Division handles the subject.

19. Which Indian authority handles extradition?

The Ministry of External Affairs is the Central Authority for extradition matters. Its Consular, Passport and Visa Division handles the relevant process.

20. What is a letter of request under Section 112 of the BNSS?

It is a formal request issued by an Indian criminal court to a competent foreign court or authority seeking the examination of a witness or the production of documents or other material located abroad.

21. Can a foreign state request evidence located in India?

Yes. Section 113 of the BNSS provides for the execution in India of qualifying letters of request received from foreign courts or competent authorities. The Central Government may forward the request to a judicial authority or a police officer for execution in accordance with the provision.

22. Can an Indian police officer arrest a suspect in another country?

Not simply by relying on an Indian arrest warrant. Indian police officers cannot ordinarily exercise coercive powers in foreign territory. Arrest and surrender must take place through the applicable legal cooperation and extradition procedures.

23. Is an Interpol Red Notice an international arrest warrant?

No. A Red Notice is a request to locate a person and, where appropriate, provisionally arrest that person pending extradition or similar legal action. Its legal effect depends on the domestic law of the country where the person is located.

24. Can foreign evidence be used in an Indian criminal trial?

Yes, where it satisfies the applicable legal and evidentiary requirements. Its authenticity, method of collection, certification, reliability, and relevance may all be examined by the court.

25. Can India freeze assets located in another country?

Indian authorities cannot ordinarily exercise direct coercive powers over property situated abroad. They may seek assistance from the foreign state through applicable treaties, conventions, and statutory mechanisms. The requested state must act under its own legal framework.
