The Jurisdiction of the U.S. Supreme Court

The Jurisdiction of the U.S. Supreme Court

The jurisdiction of the U.S. Supreme Court defines the kinds of legal disputes the nation’s highest court has authority to hear and decide. Although the Supreme Court is the highest court in the United States, it does not have unlimited authority over every legal dispute in the country.

The Constitution establishes the Supreme Court and identifies broad categories of federal judicial power. Congress has also enacted statutes that regulate much of the Court’s jurisdiction and the procedures through which cases reach it.

The Supreme Court has two fundamental forms of jurisdiction: original jurisdiction and appellate jurisdiction.

Original jurisdiction allows the Court to hear certain cases in the first instance. Appellate jurisdiction allows it to review decisions made by lower courts. In practice, appellate jurisdiction is overwhelmingly more important because most Supreme Court cases arrive through appellate review.

Even when a case appears to involve an important federal question, however, several additional requirements may prevent the Court from deciding it. The Court generally needs an actual case or controversy, the parties must satisfy constitutional requirements such as standing, the case must fall within the Court’s jurisdiction, and the procedural route to Supreme Court review must be legally available.

Understanding Supreme Court jurisdiction is therefore essential to understanding what the Court can hear, what it cannot hear, and why the Court decides some cases while leaving others to lower courts.

For a broader explanation of federal jurisdiction, readers can consult Cornell Law School Legal Information Institute’s Wex materials on jurisdiction. Supreme Court jurisdiction, however, has its own distinctive constitutional and statutory framework.

1. What Does “Jurisdiction” Mean?

In its most basic sense, jurisdiction means legal authority to hear and decide a case.

A court may have jurisdiction over a particular dispute because the Constitution or a statute gives it authority to adjudicate that type of case.

Jurisdiction is therefore different from simply having an opinion about a legal question.

A court may believe that an issue is important but still lack authority to decide it.

For the Supreme Court, jurisdiction determines whether the Court may lawfully exercise judicial power over the particular dispute presented.

This makes jurisdiction one of the first questions that must be considered in Supreme Court litigation.

2. The Constitutional Foundation of Supreme Court Jurisdiction

The principal constitutional foundation for Supreme Court jurisdiction is Article III of the U.S. Constitution.

Article III establishes the federal judicial power and provides that it extends to specified categories of cases and controversies.

The Constitution also distinguishes between the Supreme Court’s original jurisdiction and appellate jurisdiction.

Article III provides that the Supreme Court has original jurisdiction in certain categories of cases and appellate jurisdiction in others, subject to such exceptions and regulations as Congress may make.

This language establishes an important constitutional framework, but it does not by itself provide a complete procedural description of every case the Court may hear.

Congress has enacted statutes that specify and regulate much of the Court’s jurisdiction.

3. The Supreme Court Does Not Have Unlimited Jurisdiction

The phrase “Supreme Court” can create the mistaken impression that the Court can review anything.

It cannot.

The Court’s authority is limited by:

• the Constitution;
• federal statutes;
• the case-or-controversy requirement;
• standing;
• ripeness;
• mootness;
• other justiciability doctrines;
• procedural requirements;
• the nature of the lower-court decision;
• and other jurisdictional limitations.

The Court therefore operates within a legal framework that determines whether a particular dispute can properly be brought before it.

Being the highest court does not mean being a court of unlimited jurisdiction.

4. The Two Basic Types of Supreme Court Jurisdiction

The Supreme Court’s jurisdiction can be divided into two principal categories:

Original jurisdiction

The Court hears the case in the first instance.

Appellate jurisdiction

The Court reviews a decision made by another court.

These two forms of jurisdiction are fundamentally different.

Most Supreme Court litigation involves appellate jurisdiction.

Original-jurisdiction cases are comparatively rare.

5. What Is Original Jurisdiction?

Original jurisdiction means that a court has authority to hear a case at the beginning of the judicial process rather than merely reviewing a lower court’s decision.

The Supreme Court’s Constitutionally recognized original jurisdiction includes cases affecting:

• ambassadors;
• other public ministers and consuls; and
• cases in which a state is a party.

The Constitution establishes the basic categories, while federal statutes and judicial decisions help determine how that jurisdiction operates in practice.

Original jurisdiction is therefore a specialized component of the Court’s authority.

6. Cases Between States

The most significant practical category of Supreme Court original jurisdiction involves disputes between states.

States are sovereign governmental entities within the federal system.

Consequently, certain disputes between states cannot simply be treated as ordinary private litigation in a state trial court.

The Supreme Court has authority to exercise original jurisdiction over qualifying controversies between states.

Examples can include disputes involving:

• state boundaries;
• interstate water rights;
• competing claims to natural resources;
• interstate obligations;
• and other controversies in which states have legally cognizable claims against one another.

These cases are unusual because the Supreme Court is functioning as the initial judicial forum rather than reviewing a lower-court judgment.

7. Does the Supreme Court Have to Hear Every Original-Jurisdiction Case?

Not necessarily.

The existence of original jurisdiction does not mean that every possible original-jurisdiction dispute must be accepted and litigated in exactly the same manner as an ordinary appeal.

The Court has developed doctrines governing how it exercises its original jurisdiction.

In some circumstances, the Court may decline to exercise original jurisdiction even though constitutional authority exists.

This reflects the distinction between having jurisdiction and choosing how to exercise that jurisdiction.

8. The Court’s Original Jurisdiction Is Relatively Rare

Most Americans will never encounter a Supreme Court case through original jurisdiction.

The overwhelming majority of Supreme Court cases come through appellate channels.

The Court’s original-jurisdiction docket is therefore a specialized part of its work.

This is one reason the phrase “Supreme Court jurisdiction” is often used primarily in discussions of appellate review.

9. What Is Appellate Jurisdiction?

Appellate jurisdiction means the authority to review a decision made by another court.

This is the principal way in which cases reach the Supreme Court.

A dispute may begin in:

• a federal district court;
• a federal court of appeals;
• or, in qualifying circumstances, a state court.

A party may then seek Supreme Court review of a decision presenting a federal question within the Court’s authority.

The Supreme Court does not generally function as a mandatory appellate court that must hear every case brought to it.

Instead, much of its appellate jurisdiction is exercised discretionarily.

10. The Supreme Court and Federal Courts of Appeals

The most common pathway to Supreme Court review is through the federal courts of appeals.

The basic structure is:

Federal District Court

↓

Federal Court of Appeals

↓

U.S. Supreme Court

A federal district court first decides the case.

An appropriate appeal may then be taken to the relevant federal court of appeals.

After the appellate court issues its decision, a party may petition the Supreme Court for review.

The Supreme Court then decides whether to grant review.

Thus, Supreme Court appellate jurisdiction does not mean that every case automatically moves upward through the judicial hierarchy.

11. Supreme Court Review of State Courts

The Supreme Court can also review certain decisions of the highest state court in which a decision could be had, when the case presents an appropriate federal question.

This authority is important because state courts frequently decide questions involving federal law and the U.S. Constitution.

For example, a state court may decide a criminal case involving the Fourth Amendment.

A state court may interpret a federal statute.

A state supreme court may decide whether a state law violates the U.S. Constitution.

When the relevant legal requirements are satisfied, the Supreme Court may review the federal issue.

The Supreme Court therefore serves as the final judicial authority for federal questions even when the litigation originated in the state court system.

12. The Supreme Court Is Not a General State-Appellate Court

The Supreme Court does not function as a general court of appeals for state law.

If a state supreme court interprets only a provision of state law and the dispute presents no qualifying federal issue, the U.S. Supreme Court generally has no authority to reconsider the state court’s interpretation simply because one party disagrees with it.

State courts are the final authorities on the meaning of their own state laws, subject to the federal Constitution and applicable federal law.

The Supreme Court’s review of state-court decisions is therefore principally concerned with federal questions.

13. Federal Questions and Supreme Court Jurisdiction

A federal question is a legal issue arising under the U.S. Constitution, federal statutes, federal treaties, or other sources of federal law within federal judicial authority.

Federal questions are particularly important to Supreme Court jurisdiction.

Examples include disputes concerning:

• constitutional rights;
• federal criminal statutes;
• federal administrative law;
• federal taxation;
• federal intellectual property law;
• federal civil-rights statutes;
• federal environmental statutes;
• federal employment law;
• federal preemption; and
• the relationship between federal and state authority.

Not every federal question will be reviewed by the Supreme Court.

The Court has discretion over much of its appellate docket.

14. Jurisdiction and Justiciability Are Not the Same Thing

Jurisdiction and justiciability are closely related but should not be treated as identical.

Jurisdiction concerns the court’s legal authority to hear the case.

Justiciability concerns whether the dispute is the type of controversy that the federal judiciary can appropriately decide.

The doctrines of:

• standing;
• ripeness;
• mootness;
• political question; and
• prohibition against advisory opinions

are central to this analysis.

A case can involve an important federal question and still be unsuitable for judicial resolution.

15. The Case-or-Controversy Requirement

Article III limits federal judicial power to actual cases and controversies.

The requirement prevents federal courts from functioning as advisory bodies that issue legal opinions in the abstract.

The Supreme Court therefore generally requires an actual dispute between parties with a legally sufficient stake.

This requirement is fundamental.

Even if Congress passes an important law or the President takes a controversial action, the Supreme Court cannot simply issue a general ruling on its legality without a proper judicial controversy.

16. Standing

Standing asks whether the particular plaintiff has the legal capacity required to invoke federal judicial power.

A plaintiff generally must demonstrate the constitutionally required elements of standing, including an injury that is sufficiently concrete and connected to the challenged conduct and that can be addressed through the requested relief.

Standing prevents the Supreme Court from deciding abstract disagreements brought by people who have not suffered the necessary kind of injury.

For example, a person may strongly object to a federal policy but lack standing to challenge it.

The underlying policy may be controversial, yet the Court may still be unable to reach the merits.

17. Ripeness

Ripeness concerns whether a dispute has developed sufficiently for judicial resolution.

A claim may be premature if the challenged governmental action has not yet produced the kind of concrete legal consequences necessary for judicial review.

The Supreme Court may therefore decline to decide an issue because it is not yet ripe.

This doctrine prevents courts from deciding questions based primarily on speculation about future events.

18. Mootness

Mootness concerns whether an actual controversy continues to exist.

Suppose a dispute was live when the case began but circumstances later change so that the parties no longer have a meaningful dispute.

The Supreme Court may then be unable to decide the merits.

There are exceptions to ordinary mootness principles, but the basic rule reflects Article III’s requirement of a continuing case or controversy.

19. Advisory Opinions

The Supreme Court generally cannot issue advisory opinions.

An advisory opinion would answer a legal question without the concrete dispute required for the exercise of federal judicial power.

For example, the President cannot ordinarily ask the Supreme Court to provide a general opinion about whether a hypothetical future executive action would be constitutional.

There must be a proper case or controversy.

This principle is one of the most important limits on Supreme Court jurisdiction.

20. The Political Question Doctrine

The political question doctrine can also limit judicial review.

Certain constitutional questions may be considered inappropriate for judicial resolution because they are constitutionally committed to another branch of government or lack judicially manageable standards.

The fact that a dispute concerns politics does not automatically make it a political question.

The doctrine is concerned with the constitutional character of the particular dispute.

The Supreme Court must determine whether the matter falls within the judiciary’s proper role.

21. Statutory Regulation of Supreme Court Jurisdiction

Although Article III provides the constitutional foundation for Supreme Court jurisdiction, Congress has significant authority to regulate the federal judicial system.

Federal statutes establish much of the Court’s appellate jurisdiction and procedures.

Congress can therefore affect the categories of cases that may reach the Supreme Court, subject to constitutional limitations.

This creates an important interaction between Congress and the judiciary.

The Constitution establishes the judicial power.

Congress establishes much of the statutory framework through which that power is exercised.

22. Congress and the Supreme Court’s Appellate Jurisdiction

Article III contains the important phrase that the Supreme Court’s appellate jurisdiction exists “with such Exceptions, and under such Regulations as the Congress shall make.”

This language has generated substantial constitutional discussion about the relationship between congressional authority and the Supreme Court’s appellate jurisdiction.

Congress has exercised substantial authority over the Court’s appellate jurisdiction.

At the same time, Congress cannot simply eliminate constitutional judicial power in a manner that violates other constitutional requirements.

The precise limits of congressional control over Supreme Court jurisdiction have therefore been the subject of extensive constitutional debate.

23. The Writ of Certiorari

The principal modern mechanism for Supreme Court appellate review is the writ of certiorari.

A party seeking review generally files a petition asking the Court to grant certiorari.

The Court then determines whether the case warrants review.

This is different from an ordinary appeal as of right.

A party can petition for Supreme Court review without having an automatic right to have the Court hear the case.

The discretionary nature of certiorari is central to the modern Supreme Court.

24. Certiorari and Jurisdiction

Certiorari does not create jurisdiction where none exists.

The Court must have legal authority to hear the case before certiorari can operate as the procedural mechanism for review.

In other words:

Jurisdiction answers whether the Court has authority.

Certiorari provides the principal mechanism through which the Court chooses to exercise appellate review.

This distinction is fundamental.

25. Why the Supreme Court Denies Many Petitions

The Supreme Court receives thousands of petitions for certiorari and grants review in only a small fraction of them.

A petition can be denied for many reasons.

The case may:

• lack sufficient national importance;
• present an issue that is not adequately developed;
• be procedurally unsuitable;
• involve no significant conflict among lower courts;
• be controlled by existing precedent;
• lack a sufficiently important legal question;
• or simply not warrant the Court’s limited resources.

A denial of certiorari does not ordinarily mean that the Supreme Court agrees with the lower court’s reasoning.

It means that the Court has declined to review the case.

26. Finality of Lower-Court Decisions

When the Supreme Court declines to review a case, the lower court’s judgment generally remains in effect.

The denial does not transform the lower court’s decision into Supreme Court precedent.

This distinction is particularly important in legal research.

A lower-court decision remains governed by its own precedential status.

The Supreme Court’s refusal to hear the case does not ordinarily constitute an endorsement of every proposition contained in that decision.

27. Direct Appeals to the Supreme Court

Historically, certain cases could reach the Supreme Court through direct appeals.

Congress has significantly changed the Court’s appellate structure over time.

Today, certiorari is the principal mechanism for discretionary review.

Certain specialized statutory procedures may still exist, and Supreme Court jurisdiction must therefore be analyzed under the current constitutional and statutory framework rather than assuming that every case follows exactly the same procedural route.

28. The Supreme Court and Lower Federal Courts

The Supreme Court’s jurisdiction must also be understood in relation to the lower federal judiciary.

Federal district courts exercise trial-level jurisdiction.

Federal courts of appeals exercise intermediate appellate jurisdiction.

The Supreme Court exercises final appellate authority over qualifying federal questions.

This hierarchy creates a system in which the Supreme Court does not need to hear every dispute in order to establish nationwide legal rules.

It can select representative cases involving questions that warrant authoritative resolution.

29. The Supreme Court and Circuit Splits

One reason the Court may grant certiorari is the existence of a circuit split.

Suppose the Second Circuit interprets a federal statute one way and the Ninth Circuit interprets the same statute differently.

Federal district courts within those circuits are generally bound by the precedent of their respective appellate courts.

The resulting disagreement can create uncertainty.

The Supreme Court may eventually accept a case presenting the conflict and establish a national interpretation.

A circuit split is therefore one of the circumstances in which the Court’s appellate jurisdiction becomes particularly important to the national legal system.

30. The Supreme Court and Uniform Federal Law

The Court’s appellate jurisdiction allows it to promote greater uniformity in federal law.

Without a national court of last resort, different federal circuits could develop permanently conflicting interpretations of important federal statutes or constitutional principles.

The Supreme Court cannot eliminate every disagreement.

But its authority to review selected cases provides a mechanism for resolving some of the most consequential conflicts.

This is one of the principal institutional reasons the Supreme Court exists.

31. Supreme Court Jurisdiction and State Sovereignty

The Supreme Court’s authority over state-court decisions must be understood within the federal structure of the United States.

States retain their own constitutions, statutes, courts, and governmental institutions.

The Supreme Court does not generally supervise state courts as if they were subordinate state agencies.

Instead, it exercises federal judicial authority over qualifying federal questions.

A state court remains the authoritative interpreter of its own state’s law, but it must comply with controlling federal constitutional and federal-law requirements.

This relationship is a central feature of American federalism.

32. The Supreme Court and State Supreme Courts

State supreme courts are generally the highest judicial authorities within their respective state systems.

The U.S. Supreme Court is not simply a “higher state supreme court.”

The two institutions belong to different judicial systems.

A state supreme court can be the final authority on a purely state-law question.

The U.S. Supreme Court can nevertheless review a state-court judgment when the case presents a qualifying federal issue.

The distinction between state-law finality and federal-question review is essential.

33. Jurisdiction Does Not Guarantee a Particular Result

Having jurisdiction does not mean that the Supreme Court will rule in favor of the party invoking its authority.

Jurisdiction answers a threshold question:

Does the Court have legal authority to decide this case?

The merits answer a different question:

Who is legally correct?

The Court may have jurisdiction and ultimately rule against the petitioner.

Conversely, the Court may never reach the merits because jurisdiction or justiciability is lacking.

Keeping these concepts separate prevents significant confusion about Supreme Court litigation.

34. Jurisdiction and the Merits

A jurisdictional question can sometimes be intertwined with the substantive legal issue.

For example, a federal statute may determine both:

• whether a federal court has authority to hear a particular claim; and
• what substantive rights the statute creates.

Courts must distinguish jurisdictional requirements from merits questions where the governing law requires that distinction.

The Supreme Court has repeatedly emphasized the importance of identifying whether a statutory requirement is truly jurisdictional or instead concerns the merits or procedural operation of a claim.

This is one reason jurisdiction can be a sophisticated area of federal law.

35. The Court Can Decline to Reach the Merits

Even when the parties present a major constitutional question, the Court may resolve the case on another ground.

For example, the Court may determine that:

• the plaintiff lacks standing;
• the dispute is moot;
• the issue is not ripe;
• the claim was procedurally barred;
• the Court lacks jurisdiction; or
• another threshold issue prevents reaching the constitutional question.

This reflects a fundamental principle of judicial restraint.

Courts generally should not decide broader constitutional questions unnecessarily when a case can be resolved on narrower grounds.

36. Original Jurisdiction vs. Appellate Jurisdiction

The distinction can be summarized as follows:

Feature	Original Jurisdiction	Appellate Jurisdiction
Basic function	Hear a case initially	Review a lower-court decision
Typical Supreme Court use	Rare	Predominant
Lower-court decision required?	No	Generally yes
Major example	Certain disputes between states	Review of federal or state appellate decisions
Purpose	Initial adjudication	Review and resolution of legal questions
Common procedural route	Specialized original proceedings	Primarily certiorari

The two forms of jurisdiction are complementary but fundamentally different.

37. Supreme Court Jurisdiction and the Constitution

The Court’s jurisdiction cannot be separated from constitutional structure.

The Constitution establishes:

• federal judicial power;
• the Supreme Court;
• limitations based on cases and controversies;
• original jurisdiction categories;
• appellate jurisdiction;
• and the broader separation-of-powers framework.

Congress then legislates within that constitutional structure.

The Supreme Court interprets the Constitution and the statutes governing its own jurisdiction.

This produces an unusual institutional relationship in which the Court is often asked to determine the boundaries of its own judicial authority.

38. The Court’s Jurisdiction Is Different From Its Influence

The Supreme Court can have enormous influence beyond the number of cases it actually decides.

A single decision may establish a legal rule affecting courts throughout the country.

But the Court’s jurisdiction remains limited.

It does not possess general authority to review every government action, every court decision, or every legal disagreement.

Its influence is therefore much broader than its docket, but its legal authority remains bounded.

39. A Practical Example

Imagine that a federal district court in Texas decides a case involving the interpretation of an important federal statute.

The losing party appeals to the Fifth Circuit.

The Fifth Circuit issues a decision interpreting the statute.

The party seeking further review files a petition for certiorari in the Supreme Court.

At this point, several different questions arise.

First:

Does the Supreme Court have appellate authority over the type of dispute?

If so, the next question is:

Is there an appropriate procedural basis for Supreme Court review?

Then:

Should the Court grant certiorari?

If the Court grants review, it can consider the merits.

If the Court denies review, the Fifth Circuit’s judgment ordinarily remains in place.

This example demonstrates that jurisdiction, appellate procedure, and discretionary review are separate but interconnected concepts.

40. Another Example: A State Court Case

Imagine that a state supreme court decides a case involving a state statute.

The losing party argues that the state court interpreted the state constitution incorrectly.

If the dispute involves only state law, the U.S. Supreme Court generally has no authority to act as a general reviewer of the state supreme court’s interpretation.

But suppose the party argues instead that the state law violates the U.S. Constitution.

Now a federal question may exist.

If the other requirements for Supreme Court review are satisfied, the U.S. Supreme Court may have authority to review the federal constitutional issue.

The Court’s jurisdiction therefore depends heavily on the source of the legal question being presented.

41. Why Jurisdiction Matters Before Filing in the Supreme Court

Before seeking Supreme Court review, a litigant must carefully analyze:

• the source of the Court’s jurisdiction;
• the identity of the lower court;
• the nature of the judgment;
• whether a federal question exists;
• whether the issue remains live;
• whether standing exists;
• whether the issue is ripe;
• whether the case is procedurally suitable;
• whether Supreme Court review is available; and
• whether the Court is likely to consider the issue sufficiently important to warrant review.

The Court’s extraordinary institutional importance does not eliminate the need for careful procedural analysis.

Quite the opposite.

Because Supreme Court review is so limited, jurisdictional and procedural precision is essential.

Frequently Asked Questions

What is Supreme Court jurisdiction?

Supreme Court jurisdiction is the legal authority of the U.S. Supreme Court to hear and decide particular categories of cases.

What are the two types of Supreme Court jurisdiction?

The two fundamental categories are original jurisdiction and appellate jurisdiction.

What is original jurisdiction?

Original jurisdiction allows the Supreme Court to hear certain cases in the first instance rather than reviewing a lower court’s decision.

What is the most important example of Supreme Court original jurisdiction?

Disputes between states are among the most important examples of the Court’s original jurisdiction.

Does the Supreme Court hear many original-jurisdiction cases?

No. Original-jurisdiction cases are relatively uncommon compared with the Court’s appellate docket.

What is appellate jurisdiction?

Appellate jurisdiction is the authority to review a decision made by a lower court.

Can the Supreme Court review state-court decisions?

Yes, when a qualifying federal question is properly presented and the constitutional and statutory requirements for Supreme Court review are satisfied.

Can the Supreme Court review every decision of a state supreme court?

No. The Supreme Court is not a general reviewer of state law. It generally requires a qualifying federal issue.

What is certiorari?

Certiorari is the principal mechanism through which the Supreme Court exercises discretionary appellate review. A party petitions the Court to review a lower-court decision.

Does every party have a right to Supreme Court review?

No. Most Supreme Court appellate review is discretionary. The Court decides which petitions it will grant.

What is the difference between jurisdiction and certiorari?

Jurisdiction concerns whether the Court has legal authority to hear the case. Certiorari is the principal procedural mechanism through which the Court chooses to exercise appellate review.

Can the Supreme Court hear a case without an actual controversy?

Generally, no. Article III requires a qualifying case or controversy.

What happens if a plaintiff lacks standing?

The Court generally cannot reach the merits because the plaintiff has not established the constitutional basis necessary to invoke federal judicial power.

What is a circuit split?

A circuit split occurs when federal courts of appeals adopt conflicting interpretations of the same federal legal issue. Such conflicts can sometimes encourage the Supreme Court to grant certiorari.

Can Congress control Supreme Court jurisdiction?

Congress has significant authority to regulate the Court’s appellate jurisdiction under the constitutional framework, although congressional power remains subject to constitutional limitations.

Does having Supreme Court jurisdiction mean the Court must hear the case?

No. The Court may possess jurisdiction while still declining to grant discretionary review.

Does denial of certiorari mean the Supreme Court agrees with the lower court?

Generally, no. A denial of certiorari ordinarily means only that the Court has declined to review the case.

Conclusion

The jurisdiction of the U.S. Supreme Court is the legal foundation that determines the boundaries of the Court’s judicial authority.

Although the Supreme Court is the highest court in the United States, it is not a court of unlimited jurisdiction. Its authority is defined by Article III, federal statutes, and the constitutional requirements governing federal judicial power.

The Court’s two fundamental forms of jurisdiction are original jurisdiction and appellate jurisdiction. Original jurisdiction allows the Court to hear certain disputes in the first instance, most notably qualifying controversies involving states. Appellate jurisdiction allows the Court to review decisions from lower courts and is the overwhelmingly more common route through which Supreme Court cases arise.

Even then, appellate jurisdiction does not mean automatic review. The Court’s docket is highly selective. Certiorari allows the justices to determine which cases warrant review, while standing, ripeness, mootness, the case-or-controversy requirement, and other doctrines impose additional limits on judicial power.

The result is a carefully structured system. The Supreme Court has extraordinary authority, but that authority operates within defined constitutional and statutory boundaries.

Understanding those boundaries is essential to understanding the Court itself. Before asking what the Supreme Court will decide, one must first ask the more fundamental question:

Does the Supreme Court have the authority to decide it at all?
