Discovery Disputes and Motions to Compel
Discovery is intended to allow parties to obtain relevant, nonprivileged information needed to prepare their cases. But discovery does not always proceed cooperatively. Parties may disagree about whether a request is relevant, whether it is proportional, whether it is too broad, whether the response is complete, whether information is privileged, whether electronically stored information must be searched, or whether the responding party has properly preserved and produced evidence.
When the parties cannot resolve such disagreements, the federal civil rules provide mechanisms for judicial intervention. One of the most important is the motion to compel discovery under Federal Rule of Civil Procedure 37(a).
A motion to compel asks the court to order a party—or in certain circumstances another person subject to the applicable discovery rules—to provide discovery that the requesting party believes has been improperly withheld, inadequately answered, or improperly limited.
Cornell Law School’s Federal Rule of Civil Procedure 37 is the principal federal rule governing motions to compel and many discovery sanctions. Discovery disputes must also be understood in light of Federal Rule of Civil Procedure 26, which establishes the general scope and proportionality limits of discovery.
A motion to compel is therefore not simply a complaint that the opposing party has been difficult. It is a procedural request asking the court to determine whether the discovery sought falls within the rules and, if so, whether the responding party must provide it.
What Is a Discovery Dispute?
A discovery dispute arises when parties disagree about the scope, adequacy, timing, method, or legality of discovery.
Disputes can arise from virtually every discovery device, including:
- interrogatories;
- requests for production;
- requests for admission;
- depositions;
- expert discovery;
- electronically stored information;
- initial disclosures;
- supplemental disclosures;
- privilege claims;
- work-product claims.
The disagreement may concern either the request itself or the response to the request.
For example, a requesting party may believe that a document request is properly limited to records concerning the transaction at issue.
The responding party may argue that the request is overly broad, unduly burdensome, irrelevant, or disproportionate.
Alternatively, the request may be valid, but the responding party may provide an incomplete production.
Either situation can lead to a discovery dispute.
Discovery Is Not Self-Enforcing
The discovery rules establish obligations, but parties do not always comply voluntarily.
A party cannot generally ask the opposing party to comply with every discovery request simply by declaring that the request is valid.
If a dispute remains unresolved, judicial intervention may be necessary.
This is where the motion to compel becomes important.
The basic sequence is often:
Discovery request → objection or inadequate response → meet and confer → unresolved dispute → motion to compel → opposition → court ruling → compliance or further consequences
The exact procedure depends on the applicable federal rules, local rules, scheduling orders, and the judge’s standing orders.
Federal Rule of Civil Procedure 37(a)
Rule 37(a) governs motions for an order compelling disclosure or discovery.
The rule permits a party seeking discovery to move for an order compelling disclosure or discovery when the opposing party fails to provide information required by the discovery rules.
The rule covers several situations, including failures involving:
- initial disclosures;
- answers to interrogatories;
- production of documents or ESI;
- inspection;
- deposition testimony;
- other discovery obligations.
The central idea is straightforward:
When a party believes the other side has improperly failed to provide required discovery, it may ask the court to order compliance.
A Motion to Compel Is Not the Same as a Discovery Request
This distinction is important.
A discovery request is served on another party.
A motion to compel is submitted to the court.
For example:
Plaintiff serves Defendant with a request for production.
That is discovery.
If Defendant refuses to produce relevant documents and the parties cannot resolve the dispute:
Plaintiff files a motion asking the court to compel production.
That is a motion to compel.
The court’s involvement therefore generally comes after the parties have attempted to resolve the disagreement themselves.
The Meet-and-Confer Requirement
One of the most important practical principles in discovery litigation is the obligation to attempt to resolve disputes without immediately asking the judge to intervene.
Federal Rule 37(a)(1) generally requires a motion to compel to include a certification that the movant has in good faith conferred or attempted to confer with the opposing party in an effort to obtain the discovery without court action.
This requirement reflects a broader philosophy of federal civil procedure:
Discovery disputes should ordinarily be resolved by the parties when reasonably possible.
Many federal district courts impose additional and more detailed local requirements concerning the meet-and-confer process.
What Does “Meet and Confer” Mean?
A meet and confer is a genuine effort to resolve the discovery dispute.
It is not merely sending an email stating:
“You must produce the documents or we will file a motion.”
A meaningful effort may involve:
- identifying the disputed requests;
- explaining why the requesting party believes the response is inadequate;
- explaining the objection;
- discussing narrowing the request;
- identifying documents that can be produced;
- negotiating search terms;
- discussing custodians;
- discussing confidentiality;
- discussing production format;
- resolving partial disputes;
- identifying the precise issues that remain.
The goal is to reduce the dispute before involving the court.
Good Faith Matters
The meet-and-confer requirement is generally intended to be substantive rather than ceremonial.
A party that files a motion to compel without making a genuine effort to resolve the dispute may face procedural consequences.
Courts may:
- deny the motion;
- require another meet and confer;
- defer consideration;
- award expenses;
- criticize counsel’s conduct;
- impose other appropriate consequences under applicable rules.
Local rules may be especially specific about what constitutes an adequate conference.
Narrowing the Dispute
One of the most effective ways to resolve discovery disputes is to narrow them.
Suppose a request seeks:
“All communications concerning the defendant’s business operations.”
The responding party objects that the request is enormously broad.
Rather than immediately litigating the objection, the parties might negotiate:
“All communications between January 1 and March 31 concerning the contract at issue, including communications with the identified vendor.”
The revised request may eliminate much of the dispute.
Discovery litigation often becomes more manageable when the parties identify what information is genuinely necessary rather than defending absolute positions.
What Can a Motion to Compel Seek?
A motion to compel can seek different forms of relief depending on the discovery problem.
For example, a party may ask the court to order the opposing party to:
- answer an interrogatory;
- provide a complete interrogatory answer;
- produce documents;
- produce ESI;
- permit inspection;
- answer deposition questions;
- provide a required disclosure;
- supplement an inadequate response;
- provide information withheld on an improper objection;
- comply with a discovery obligation.
The requested relief should correspond specifically to the actual discovery failure.
Compelling an Answer to an Interrogatory
Suppose an interrogatory asks:
Identify each person who participated in negotiating the contract.
The responding party answers:
“Various employees participated.”
The requesting party may argue that the response is inadequate because it does not identify the requested individuals.
A motion to compel could ask the court to require a complete answer.
The court would then consider the wording of the interrogatory, the applicable discovery rules, any objections, and the circumstances of the case.
Compelling Production of Documents
Requests for production are another common source of disputes.
Suppose a plaintiff requests:
“All emails between Defendant and the supplier concerning the disputed transaction.”
The defendant responds:
“Objection: overly broad and burdensome.”
The plaintiff may challenge the objection if the request is actually limited to a particular supplier and transaction.
The court may determine that the objection is unjustified and order production.
Alternatively, the court might narrow the request or impose conditions.
Evasive or Incomplete Responses
A discovery response does not necessarily comply with the rules merely because something was technically said.
An evasive or incomplete response may be treated as a failure to respond.
For example, if a party is asked to identify all witnesses with knowledge of a transaction and responds:
“The company has many employees who may have relevant information.”
that may be considered inadequate if the request requires actual identification of known witnesses.
The same principle applies to document production.
Producing a small number of documents while withholding responsive documents without adequate justification may support a motion to compel.
Boilerplate Objections
One of the most common discovery disputes involves boilerplate objections.
Examples include:
“Overly broad.”
“Unduly burdensome.”
“Irrelevant.”
“Vague.”
“Not proportional.”
“Calls for privileged information.”
Such objections may be legitimate in appropriate circumstances.
But simply stating an objection without explaining its factual and legal basis may be inadequate.
A proper objection should generally identify the specific problem and, where appropriate, explain the scope of the objection.
Partial Objections and Partial Compliance
A party may object to part of a discovery request while responding to the remainder.
For example:
“Defendant objects to the request insofar as it seeks documents concerning unrelated products. Subject to that objection, Defendant will produce responsive documents concerning the product involved in this action.”
This approach can be preferable to refusing the entire request when only part of the request is objectionable.
Discovery disputes frequently arise when a party uses an objection to withhold information that is actually outside the scope of the objection.
The Court’s Role in Interpreting Discovery Requests
Courts may need to interpret the wording of the discovery request itself.
The court can consider:
- ordinary meaning;
- definitions used in the request;
- the pleadings;
- claims and defenses;
- prior discovery;
- the circumstances of the dispute;
- proportionality;
- relevance;
- privilege;
- burden.
A discovery request should not normally be interpreted in complete isolation from the case.
Its relationship to the claims and defenses matters.
Relevance in a Motion to Compel
A party seeking discovery generally must establish that the requested information falls within the permissible scope of discovery.
Under Rule 26(b)(1), discovery generally concerns nonprivileged matter relevant to a party’s claim or defense and proportional to the needs of the case.
The information need not itself be admissible at trial.
This is an important distinction.
Discovery is designed in part to help parties determine what evidence exists and develop their cases.
But relevance is not unlimited.
A party cannot demand information merely because it might conceivably lead to something interesting.
Proportionality
Modern federal discovery places substantial emphasis on proportionality.
The proportionality analysis considers factors including:
- the importance of the issues at stake;
- the amount in controversy;
- the parties’ relative access to information;
- the parties’ resources;
- the importance of the discovery in resolving the issues;
- whether the burden or expense of the proposed discovery outweighs its likely benefit.
A motion to compel may therefore become a dispute not about whether information has some relevance, but whether obtaining it is justified in light of the case as a whole.
Burden and Expense
A responding party may argue that compliance would impose excessive burden or expense.
But “burdensome” is not always enough.
Courts may expect the party asserting burden to explain the burden with sufficient specificity.
For example, a party may need to explain:
- how many documents are involved;
- how many custodians must be searched;
- what systems contain the information;
- how difficult the information is to retrieve;
- what technology is required;
- how much time the search would require;
- what costs would be incurred.
A generalized assertion that discovery is “expensive” may not adequately establish undue burden.
E-Discovery Disputes
Electronic discovery creates particularly complex motions to compel.
Disputes may concern:
- search terms;
- custodians;
- date ranges;
- email accounts;
- cloud storage;
- mobile devices;
- text messages;
- collaboration platforms;
- social media;
- metadata;
- native files;
- deduplication;
- document-review protocols;
- inaccessible ESI.
The parties may disagree not only about what must be produced but also about how the responding party must search for it.
ESI That Is Not Reasonably Accessible
Rule 26(b)(2)(B) addresses electronically stored information from sources that the responding party identifies as not reasonably accessible because of undue burden or cost.
The responding party bears the initial burden of showing that the information is not reasonably accessible because of undue burden or cost.
Even then, the court may order discovery if the requesting party shows good cause, potentially subject to conditions.
This means that “the data is difficult to retrieve” does not necessarily end the dispute.
The court may balance the burden against the importance of the information.
Search Methodology Disputes
A party may argue:
“We searched our email system.”
The requesting party may respond:
“Your search was inadequate because you searched only one custodian and excluded relevant date ranges.”
The court may need to determine whether the search methodology was reasonable.
Courts generally do not require perfection in every e-discovery search.
But parties are expected to cooperate and develop reasonable methods appropriate to the needs of the case.
The appropriate methodology depends heavily on the nature and complexity of the litigation.
Privilege Disputes
A party may withhold information because it claims:
- attorney-client privilege;
- work-product protection;
- another applicable privilege or protection.
The requesting party may challenge the claim.
The dispute may concern:
- whether the privilege applies;
- whether the communication was confidential;
- whether a third party was present;
- whether the communication was primarily for legal advice;
- whether work product was prepared in anticipation of litigation;
- whether privilege was waived;
- whether the claim is adequately supported.
The court may require additional information or conduct an in camera review of the disputed material.
In Camera Review
In camera review means that the judge reviews material privately rather than requiring it to be disclosed to the opposing party during the dispute.
This can be useful when the court cannot determine whether a privilege or protection applies from descriptions alone.
For example, a privilege log might describe a document as:
“Email from corporate employee to outside counsel concerning legal advice regarding anticipated litigation.”
The opposing party may dispute the characterization.
The judge may review the email privately to determine whether the claimed privilege applies.
In camera review is a judicial tool, not an automatic requirement for every privilege dispute.
Privilege Logs
Privilege disputes often involve privilege logs.
A privilege log allows the withholding party to identify documents without revealing the protected substance.
The information may include:
- date;
- author;
- recipients;
- general description;
- type of document;
- privilege or protection claimed.
A sufficiently informative log allows the opposing party and court to evaluate the claim.
A vague or incomplete privilege log may itself become the subject of a discovery dispute.
Work Product Disputes
The work product doctrine discussed in the preceding article frequently becomes relevant in motions to compel.
Suppose a party requests:
“All memoranda prepared by defense counsel concerning potential defenses.”
The responding party claims work-product protection.
The requesting party may argue that the documents are not actually work product or that the protection has been waived.
If ordinary work product is involved, the requesting party may also argue that it has substantial need and cannot obtain the substantial equivalent without undue hardship.
Opinion work product receives significantly stronger protection.
Protective Orders
A motion to compel is not the only way courts manage discovery disputes.
The responding party may seek a protective order under Rule 26(c).
A protective order can protect a party or person from:
- annoyance;
- embarrassment;
- oppression;
- undue burden;
- undue expense.
The court can impose conditions on discovery or limit the manner in which discovery occurs.
For example, a court might:
- restrict the scope of a deposition;
- limit the number of depositions;
- restrict the subjects of questioning;
- require confidential information to be filed under seal;
- limit who may receive sensitive information;
- require a different discovery method;
- limit production to a narrower category.
A protective order therefore provides an important counterpart to a motion to compel.
Motion to Compel vs. Protective Order
The two mechanisms can be understood as complementary.
Motion to Compel
The requesting party says:
“The opposing party has not provided discovery that the rules require.”
Motion for Protective Order
The responding party says:
“The requested discovery should be prohibited or limited because it would create an undue burden, expense, oppression, embarrassment, or other legally recognized harm.”
Sometimes both positions appear in the same dispute.
A court may grant one motion, deny the other, or craft a compromise order.
Sanctions and Motions to Compel
A motion to compel is not necessarily the same thing as a motion for sanctions.
A party may first ask the court to order discovery.
If the opposing party then disobeys the court’s discovery order, Rule 37(b) provides a separate framework for consequences.
Depending on the circumstances, sanctions can become serious.
They may include:
- establishing facts against the disobedient party;
- prohibiting the party from supporting or opposing particular claims or defenses;
- striking pleadings;
- staying proceedings;
- dismissing the action;
- entering default judgment;
- contempt in appropriate circumstances.
The availability and severity of sanctions depend on the nature of the violation and the governing rule.
Failure to Obey a Discovery Order
There is an important distinction between:
failing to respond to discovery
and
failing to obey a court order compelling discovery.
A party that simply fails to provide an adequate response may trigger a motion to compel.
If the court then orders the party to provide the discovery and the party disobeys that order, Rule 37(b) can provide additional and potentially much more severe consequences.
This distinction is important in understanding discovery sanctions.
Expenses and Attorney’s Fees
Rule 37 can also address the expenses incurred in connection with motions to compel.
Depending on the circumstances, the court may require the party whose conduct necessitated the motion, the party or attorney who opposed the motion, or both to pay reasonable expenses, including attorney’s fees.
But the rule contains exceptions.
For example, an award may not be appropriate where:
- the movant filed the motion before making a good-faith effort to obtain the discovery without court intervention;
- the opposing party’s nondisclosure was substantially justified;
- other circumstances make an award unjust.
The purpose is not simply to punish losing parties.
It is also to encourage reasonable cooperation in discovery.
Substantial Justification
The concept of substantial justification is important when courts consider discovery-related expenses.
A party’s position may be substantially justified when there is a genuine dispute or a reasonable basis for the position under the circumstances.
A party does not necessarily have to be legally correct to avoid every cost consequence.
The court evaluates the reasonableness of the conduct and the surrounding circumstances.
The Difference Between an Objection and a Motion to Compel
An objection is a response to a discovery request.
A motion to compel is a request for judicial intervention after a dispute has developed.
For example:
Request:
Produce all emails concerning the transaction.
Response:
Objection: the request is overbroad and disproportionate.
Follow-up:
The requesting party argues that the objection is improper and asks the responding party to produce the emails.
Motion to compel:
The requesting party asks the court to order production.
Each stage has a distinct procedural function.
Depositions and Motions to Compel
Discovery disputes do not occur only with written discovery.
They can arise during depositions.
For example, a witness may refuse to answer a question after counsel instructs the witness not to answer.
A party may seek judicial relief when the instruction is improper.
Rule 30 establishes rules governing objections and instructions not to answer during depositions.
Generally, an instruction not to answer is not supposed to be used simply because counsel dislikes the question. Specific protections and circumstances apply.
The court may also intervene when deposition conduct becomes abusive or excessively burdensome.
Incomplete Deposition Testimony
A discovery dispute can also arise when a witness:
- refuses to answer;
- gives an evasive answer;
- claims lack of preparation;
- fails to bring required materials;
- appears improperly instructed;
- is inadequately prepared for a Rule 30(b)(6) deposition.
The remedy may include a motion to compel further testimony or, depending on the circumstances, other relief under the discovery rules.
Rule 30(b)(6) Disputes
Organizational depositions can generate particularly complex disputes.
Under Rule 30(b)(6), an organization designates one or more persons to testify about matters described in the deposition notice.
The organization must prepare the designated witness or witnesses to testify about information known or reasonably available to the organization concerning the matters described in the notice.
A dispute may arise when the witness repeatedly states:
“I don’t know.”
The question then becomes whether the organization adequately prepared the witness.
Courts may evaluate the specificity of the notice, the organization’s preparation efforts, and the scope of the requested testimony.
Discovery Disputes Concerning Requests for Admission
Requests for admission create their own category of disputes.
A party may argue that the responding party:
- improperly refused to admit or deny;
- gave an inadequate denial;
- failed to make reasonable inquiry;
- improperly objected;
- treated a compound request as invalid;
- failed to respond on time.
Because unanswered requests for admission can have significant consequences, procedural compliance is particularly important.
Rule 36 provides the governing federal framework.
Discovery Disputes Concerning Interrogatories
Interrogatory disputes frequently concern:
- vague questions;
- compound questions;
- excessive subparts;
- incomplete answers;
- objections;
- failure to answer separately;
- improper claims of burden;
- business-record objections;
- inadequate factual investigation.
Rule 33 governs federal interrogatories.
A motion to compel may ask the court to require a complete answer or determine that an objection is improper.
Discovery Disputes Concerning Requests for Production
Requests for production often generate disputes over:
- relevance;
- proportionality;
- overbreadth;
- possession, custody, or control;
- privilege;
- work product;
- search methodology;
- ESI;
- production format;
- metadata;
- completeness;
- privilege logs.
Rule 34 governs these requests, while Rule 37 provides the primary federal mechanism for compelling compliance.
Cornell’s inspection of documents resource explains that Rule 34 permits requests concerning documents, ESI, and tangible things within the applicable scope of discovery and that failure to respond may lead to a motion to compel.
Discovery Disputes and Experts
Expert discovery can also lead to motions to compel.
Common disputes include:
- failure to make required disclosures;
- incomplete expert reports;
- failure to identify an expert;
- inadequate disclosure of opinions;
- failure to provide required bases and data;
- disputes over expert depositions;
- improper withholding of draft materials;
- disputes over attorney-expert communications.
Rule 26(b)(4) contains specific protections and limitations governing expert discovery.
Because expert discovery has its own structure, a court will generally analyze an expert dispute under both the general discovery rules and the specific expert provisions.
Discovery Disputes and Supplemental Responses
Discovery obligations may continue as a case develops.
If a party learns that a previous response was materially incomplete or incorrect, supplementation may become necessary under the applicable rules.
A dispute can therefore arise when one party argues:
“Your original response is no longer accurate.”
The responding party may argue:
“The original response was accurate when made.”
The court may need to determine whether a duty to supplement exists under the applicable discovery rules.
Timing Matters
Discovery disputes are highly sensitive to deadlines.
The relevant deadlines may come from:
- the Federal Rules of Civil Procedure;
- the court’s scheduling order;
- local rules;
- standing orders;
- discovery deadlines;
- deadlines established by agreement.
A party may have a strong substantive argument but still face procedural difficulties if it waits too long to raise a discovery dispute.
Federal district courts frequently impose specific deadlines for discovery motions.
Therefore, counsel should never assume that the general federal rule provides the only applicable deadline.
Local Rules Matter
Civil procedure is not governed exclusively by the Federal Rules of Civil Procedure.
Federal district courts frequently have local rules governing discovery disputes.
Some courts require:
- a specific meet-and-confer procedure;
- a joint discovery letter;
- a discovery conference with the magistrate judge;
- page limits;
- separate statements;
- specific certification language;
- shortened briefing;
- pre-motion conferences.
A lawyer preparing a motion to compel must therefore examine the rules and orders of the particular court.
The Structure of a Motion to Compel
A well-prepared motion to compel generally identifies the dispute precisely.
Although requirements vary by court, a motion commonly includes:
Introduction
A concise explanation of the discovery problem.
Background
The relevant procedural history.
The Discovery Request
The actual request at issue.
The Response or Objection
The opposing party’s response.
Meet-and-Confer History
The efforts made to resolve the dispute.
Legal Argument
Why the discovery is permissible and why the objection or response is inadequate.
Requested Relief
The precise order sought.
The strongest motions make it easy for the judge to understand exactly what remains disputed.
Avoiding an Overbroad Motion
A motion to compel should generally be as precise as possible.
If ten requests are disputed but only three present a genuine legal issue, the motion may be stronger if it clearly isolates those three issues.
Courts do not want to reconstruct an entire discovery history from hundreds of pages of correspondence.
Precision helps the court resolve the dispute efficiently.
Evidence Supporting a Motion
A motion to compel may be supported by materials such as:
- the discovery requests;
- the responses;
- objections;
- correspondence;
- declarations;
- meet-and-confer communications;
- privilege logs;
- production descriptions;
- deposition excerpts;
- relevant pleadings;
- scheduling orders.
The precise requirements depend upon the court.
The goal is to give the judge enough information to determine what was requested, what was provided, what remains disputed, and why the requesting party believes additional discovery is required.
The Opposing Party’s Response
The responding party may oppose the motion by arguing that:
- the discovery is irrelevant;
- the request is disproportionate;
- the request is vague;
- the request is overbroad;
- compliance is unduly burdensome;
- the information is privileged;
- the material is protected work product;
- the information has already been produced;
- the request seeks information outside the party’s possession, custody, or control;
- the requesting party failed to meet and confer;
- the motion is untimely;
- the requested relief is unnecessary.
The response should address the actual dispute rather than simply repeat generic objections.
Partial Victory Is Common
Discovery disputes do not always produce an all-or-nothing result.
A court may:
- grant the motion;
- deny the motion;
- grant it in part;
- deny it in part;
- narrow the request;
- require a supplemental response;
- impose conditions;
- require a confidentiality agreement;
- establish a deadline;
- order a limited search;
- require a privilege log;
- conduct in camera review.
This is particularly common when the original discovery request was broader than necessary.
The Court Can Shape the Discovery
The court’s role is not necessarily limited to answering:
“Produce everything.”
The court may design a narrower solution.
For example, instead of requiring production of ten years of emails, the court might order:
- a two-year period;
- five identified custodians;
- specified search terms;
- a particular subject matter;
- production in a specified format.
This reflects the proportionality principle.
The objective is useful discovery, not unlimited discovery.
Discovery Disputes and Cooperation
Federal civil litigation operates most effectively when counsel cooperate.
Cooperation does not mean surrendering legitimate objections.
It means:
- explaining objections;
- identifying what can be produced;
- narrowing disputes;
- proposing reasonable alternatives;
- agreeing on production formats;
- resolving issues without unnecessary judicial intervention.
A party can vigorously protect its legal position while still cooperating procedurally.
Discovery Disputes as a Strategic Problem
Discovery disputes can affect litigation strategy.
A party may use discovery to test:
- the strength of the opposing party’s factual case;
- whether key witnesses exist;
- whether documents support a claim;
- whether damages are substantial;
- whether defenses have factual support.
But excessive motion practice can become expensive and distract from the merits.
The most effective discovery strategy therefore distinguishes between disputes that materially affect the case and disputes that are merely procedural irritations.
Discovery Abuse
Discovery can be abused by either side.
Examples include:
- serving excessive requests;
- deliberately vague requests;
- refusing reasonable requests without explanation;
- using boilerplate objections;
- imposing unnecessary search burdens;
- withholding clearly responsive material;
- delaying production;
- repeatedly changing positions;
- using discovery to harass;
- refusing to cooperate in scheduling;
- making excessive motion practice part of litigation strategy.
Courts have authority to control discovery and impose consequences where appropriate.
The Principle of Proportionality in Practice
Consider two hypothetical cases.
Case One
A small dispute involves $20,000.
One party requests every email sent by the opposing company’s 300 employees over ten years.
Even if some emails could theoretically relate to the dispute, the request raises serious proportionality concerns.
Case Two
A major commercial lawsuit concerns a billion-dollar transaction.
The requested communications are held by four key executives and concern the transaction during a six-month period.
The same general type of discovery may be much more proportionate in the second case.
Discovery is therefore contextual.
Motion to Compel and the Merits of the Case
A discovery motion should not ordinarily become a substitute for deciding the entire lawsuit.
The court’s task is generally to determine whether discovery is permitted and, if necessary, how it should occur.
For example, the judge may determine that a party must produce documents relevant to a contract dispute without deciding whether those documents ultimately prove breach.
Discovery helps the parties develop the evidentiary record.
It does not necessarily resolve the substantive dispute.
Discovery Orders
When the court grants a motion to compel, it generally issues an order specifying what the responding party must do.
The order may require:
- production by a specific date;
- supplemental interrogatory answers;
- additional deposition testimony;
- a new search;
- production in a specified format;
- preparation of a witness;
- a privilege log;
- a limited document review;
- payment of expenses.
The clarity of the order matters because failure to obey a discovery order can lead to sanctions under Rule 37(b).
Failure to Comply With a Motion to Compel Order
Suppose a court orders:
“Defendant shall produce the responsive emails by October 15.”
Defendant does not comply.
The issue is now more serious than the original discovery disagreement.
The party may seek sanctions for failure to obey the court’s order.
Possible consequences can include severe measures in appropriate circumstances, particularly when noncompliance is willful, repeated, or prejudicial.
The progression can therefore be understood as:
Discovery request → dispute → motion to compel → court order → noncompliance → possible sanctions
Rule 37 Sanctions
Rule 37 provides several categories of discovery-related sanctions.
Depending upon the circumstances, a court may:
- order designated facts established;
- prohibit evidence or arguments;
- strike pleadings;
- stay proceedings;
- dismiss an action;
- enter default judgment;
- treat conduct as contempt where authorized.
The most severe sanctions are not appropriate for every discovery violation.
Courts consider the nature of the violation, the circumstances, prejudice, willfulness or bad faith where relevant, prior compliance, and other factors under the governing rule and precedent.
Discovery Disputes and Electronically Stored Information
The consequences of discovery disputes can be especially significant when ESI is involved.
A disagreement may concern whether the responding party:
- preserved relevant information;
- searched the correct accounts;
- included relevant custodians;
- searched relevant devices;
- used reasonable search methods;
- produced responsive documents;
- improperly withheld metadata;
- produced ESI in the required format.
In complex litigation, resolving these issues early can prevent enormous downstream costs.
Discovery Disputes and Preservation
A motion to compel and a preservation dispute are related but distinct.
A motion to compel generally concerns information that should be produced.
A preservation dispute concerns whether potentially relevant information was properly preserved in the first place.
Rule 37(e) specifically addresses certain failures to preserve electronically stored information that should have been preserved in anticipation or conduct of litigation and that cannot be restored or replaced through additional discovery.
The remedies under Rule 37(e) depend upon the circumstances and the level of intent and prejudice involved.
Discovery Disputes and Confidential Information
A party may possess responsive information that contains:
- trade secrets;
- confidential commercial information;
- personal information;
- financial information;
- proprietary technology.
Confidentiality alone does not necessarily eliminate discovery.
Instead, the court may use protective orders and other measures to permit legitimate discovery while limiting unnecessary disclosure.
For example, a court may allow production subject to an agreed or court-ordered confidentiality regime.
The Court’s Inherent Authority
Federal courts also possess authority to manage litigation and prevent abuse of judicial procedures.
Discovery disputes may therefore implicate not only the text of Rule 37 but also the court’s broader case-management responsibilities and applicable precedent.
Nevertheless, counsel should begin with the specific Federal Rules, local rules, and court orders governing the dispute.
A Practical Discovery-Dispute Example
Suppose a plaintiff serves a request for production:
“Produce all communications between Defendant and Supplier X concerning the contract at issue from January 1, 2024 through December 31, 2024.”
Defendant responds:
“Objection. Overly broad, unduly burdensome, irrelevant, and disproportionate.”
No documents are produced.
The plaintiff believes the request is narrowly focused and attempts to meet and confer.
During the conference, Defendant explains that it has approximately 50,000 emails involving Supplier X.
Plaintiff narrows the request to:
- six identified employees;
- the contract at issue;
- the relevant twelve-month period;
- emails containing specified transaction terms.
Defendant still refuses to produce anything.
The plaintiff may then file a motion to compel.
The motion would explain:
- the request;
- the original objection;
- the narrowing efforts;
- why the remaining request is relevant;
- why it is proportional;
- why the burden is manageable;
- why the objections should be rejected;
- precisely what production is requested.
The court might order the narrowed production rather than the original request.
This illustrates the practical purpose of the discovery-dispute process: narrowing disagreement until the court can impose a workable solution.
How Lawyers Can Avoid Discovery Motions
The best discovery motion is often the one that never has to be filed.
Counsel can reduce disputes by:
- drafting specific requests;
- avoiding unnecessarily broad demands;
- responding specifically to each request;
- producing documents on a rolling basis when appropriate;
- explaining objections;
- discussing ESI methodology early;
- creating privilege logs;
- identifying missing information promptly;
- supplementing responses when required;
- communicating professionally;
- conducting meaningful meet-and-confers.
Good discovery practice is therefore partly a matter of procedural law and partly a matter of disciplined litigation management.
The Difference Between a Strong and Weak Motion to Compel
A weak motion might say:
“Defendant refuses to cooperate and has withheld relevant evidence.”
A stronger motion identifies:
“Request for Production No. 12 seeks emails between Defendant’s two identified executives and Supplier X concerning the disputed contract during the six-month period preceding termination. Defendant objected solely on proportionality grounds and produced no documents. During the meet-and-confer, Defendant confirmed that approximately 1,200 potentially responsive emails exist. Plaintiff proposes limiting the request to communications containing the contract number or the supplier’s invoice numbers.”
The second presentation gives the court a concrete dispute that can actually be resolved.

- The proportionality principle is central to modern federal discovery.
- Discovery disputes involving ESI may concern not only production but also search methodology, accessibility, preservation, and format.
- The strongest discovery practice seeks reasonable cooperation before judicial intervention.
Frequently Asked Questions
What is a motion to compel?
A motion to compel is a request asking the court to order another party to provide discovery that the moving party believes has been improperly withheld, inadequately answered, or otherwise not provided as required.
Is a motion to compel the same as a discovery request?
No. A discovery request is served on another party. A motion to compel asks the court to intervene when the parties cannot resolve a discovery dispute.
Must parties meet and confer before filing a motion to compel?
Under Federal Rule 37(a)(1), the moving party generally must certify that it has in good faith conferred or attempted to confer with the opposing party. Local rules may impose additional requirements.
Can a court deny a motion to compel even if the information is relevant?
Yes. Relevance is only one part of the analysis. Discovery may also be limited by proportionality, privilege, work-product protection, burden, expense, and other rules.
What happens if a party gives an incomplete answer?
An incomplete or evasive response may be treated as a failure to provide discovery and can support a motion to compel.
Can a court order a party to produce electronically stored information?
Yes. ESI is expressly included within federal discovery, subject to the rules governing relevance, proportionality, accessibility, privilege, preservation, and production.
What if the requested ESI is very expensive to retrieve?
Rule 26(b)(2)(B) provides special treatment for ESI from sources that are not reasonably accessible because of undue burden or cost. A court may nevertheless order discovery upon a sufficient showing of good cause and may impose conditions.
What is a protective order?
A protective order is a court order limiting or controlling discovery to protect a party or person from annoyance, embarrassment, oppression, undue burden, or undue expense.
Can a court award attorney’s fees after a motion to compel?
Yes. Rule 37 contains provisions concerning expenses and attorney’s fees associated with motions to compel, subject to specified exceptions.
What happens if a party ignores a court order compelling discovery?
Failure to obey a discovery order can lead to sanctions under Rule 37(b), potentially including serious evidentiary or procedural consequences.
Can discovery disputes lead to dismissal of a lawsuit?
In sufficiently serious circumstances, yes. Rule 37 permits severe sanctions in appropriate cases, including dismissal or default judgment. Such sanctions are not automatic and depend on the circumstances and applicable law.
Conclusion
Discovery is designed to reduce surprise, expose relevant evidence, and allow parties to prepare their cases fairly. But the discovery system depends on cooperation as well as enforceable legal obligations.
When cooperation fails, the motion to compel becomes one of the principal tools for enforcing those obligations.
A motion to compel is not simply a complaint that opposing counsel has been uncooperative. It is a structured request for judicial enforcement of the discovery rules. The court must determine whether the requested information falls within the permissible scope of discovery, whether an objection or withholding is legally justified, whether privilege or work-product protection applies, and whether the requested discovery is proportional to the needs of the case.
The process ordinarily begins before the motion itself. Counsel should identify the disputed requests, communicate about the problem, explain their positions, narrow unnecessary issues, and attempt in good faith to reach an agreement. Only when that effort fails should judicial intervention ordinarily become necessary.
The distinction between a motion to compel and a protective order is equally important. The requesting party may ask the court to require discovery, while the responding party may ask the court to limit or prohibit discovery that creates undue burden, expense, oppression, or other recognized harm.
Finally, the consequences of discovery disputes can extend far beyond the immediate production request. Failure to comply with a court’s discovery order can result in sanctions under Rule 37, potentially affecting evidence, claims, defenses, pleadings, and even the outcome of the case.
The central principle is therefore straightforward:
Discovery is broad, but it is not unlimited; objections must have legal substance, requests must remain within the rules, and when the parties cannot resolve a genuine dispute themselves, the court can compel appropriate discovery and enforce its orders.
