Discovery in United States Law

Understanding Discovery

Discovery is the pretrial phase in litigation during which parties exchange information and evidence relevant to the case. The discovery process enables each party to obtain evidence held by the opposing party and third parties, preventing surprise at trial and promoting informed settlement negotiations. Discovery is governed by Rules 26 through 37 of the Federal Rules of Civil Procedure and analogous state rules.

The discovery process serves multiple purposes. It narrows the issues for trial by allowing parties to identify areas of genuine dispute. It provides each party with access to relevant evidence held by the other side, facilitating preparation for trial. It promotes settlement by ensuring that both parties have a realistic understanding of the strengths and weaknesses of their case. And it preserves evidence that might otherwise be lost or destroyed.

Scope of Discovery

Rule 26(b)(1) defines the scope of discovery: parties may obtain discovery regarding any nonprivileged matter that is relevant to any party’s claim or defense and proportional to the needs of the case. Proportionality considers the importance of the issues at stake, the amount in controversy, the parties’ resources, the nature of the discovery burden, and the importance of the discovery in resolving the issues.

The 2015 amendments to the Federal Rules emphasized proportionality as a central limit on discovery. Information need not be admissible at trial to be discoverable if it appears reasonably calculated to lead to admissible evidence. The proportionality requirement is intended to curb excessive discovery costs and burdens, particularly in smaller cases where discovery costs can exceed the amount in controversy.

Relevance is broadly defined for discovery purposes. Any matter that bears on or could reasonably lead to other matters that could bear on any party’s claim or defense is discoverable. The court may limit discovery if the burden or expense outweighs the likely benefit, considering the needs of the case, the amount in controversy, the parties’ resources, and the importance of the issues.

Discovery Methods

Parties may use several discovery tools. Interrogatories are written questions directed to another party, requiring sworn answers. The Federal Rules limit interrogatories to 25 (including subparts) without leave of court. Requests for production ask parties to produce documents, electronically stored information, or tangible things for inspection and copying.

Requests for admission ask parties to admit or deny specific facts. Matters admitted are conclusively established for trial. Depositions involve oral examination of witnesses under oath, transcribed by a court reporter. Depositions are limited to 10 per side and 7 hours per deposition, subject to adjustment by stipulation or court order.

Subpoenas compel nonparties to produce documents or testify at deposition. Subpoenas must comply with geographic limits and provide reasonable time for compliance. The court may quash or modify a subpoena that subjects a person to undue burden.

Physical and mental examinations are available in limited circumstances when the physical or mental condition of a party is in controversy. The court may order the examination on motion for good cause.

E-Discovery

Electronically stored information (ESI) has transformed discovery practice. Parties must preserve relevant electronic data when litigation is reasonably anticipated. The Federal Rules address e-discovery issues including the format of production, preservation obligations, and the treatment of privileged materials inadvertently produced.

The safe harbor provision in Rule 37(e) protects parties from sanctions for lost ESI resulting from routine, good-faith operations if the loss occurred despite reasonable steps to preserve the information. However, if the court finds that a party failed to take reasonable steps to preserve ESI that should have been preserved, the court may impose sanctions, including an adverse inference instruction, dismissal, or default judgment, upon a finding of prejudice and intent to deprive.

Parties must produce ESI in a reasonably usable form. The producing party may specify the form of production, and the requesting party may object. Metadata may be discoverable in certain circumstances. The costs of e-discovery are typically borne by the producing party, but the court may shift costs in appropriate cases.

Protection of Privileged Material

Discovery does not extend to privileged communications. The attorney-client privilege protects confidential communications between lawyers and clients for the purpose of legal advice. The privilege belongs to the client and may not be waived without the client’s consent. The privilege protects communications, not underlying facts; a client may be required to disclose facts even if they communicated them to their attorney.

The work-product doctrine, established in Hickman v. Taylor (1947) and codified in Rule 26(b)(3), protects materials prepared in anticipation of litigation from discovery by adversaries. Work product receives two levels of protection: opinion work product (an attorney’s mental impressions, conclusions, opinions, and legal theories) receives near-absolute protection, while ordinary work product (factual materials prepared for litigation) may be discovered upon a showing of substantial need and undue hardship.

Privilege logs must identify withheld documents with sufficient specificity to support the privilege claim. The opposing party may challenge privilege claims, and the court reviews the documents in camera to resolve disputes. Inadvertent disclosure of privileged information may not constitute a waiver if the holder took reasonable steps to prevent disclosure and to rectify it.

Discovery Abuse and Sanctions

Discovery abuse includes excessive or abusive discovery requests, failure to produce responsive materials, spoliation of evidence, and resistance to legitimate discovery. Rule 26(g) requires parties to certify that discovery requests, responses, and objections are consistent with the rules and not interposed for improper purposes.

Rule 37 provides sanctions for discovery violations, including monetary penalties, adverse inference instructions, striking pleadings, and default judgment. The court must impose sanctions for violations of discovery orders, and the sanction should be proportionate to the violation. Monetary sanctions include payment of reasonable expenses, including attorneys’ fees, caused by the violation.

Spoliation — the intentional or negligent destruction of relevant evidence — may result in severe sanctions, including an adverse inference instruction that the jury may presume the destroyed evidence was unfavorable to the spoliating party. Courts consider the degree of fault and the prejudice caused by the destruction.

Duty to Disclose

Rule 26(a) requires initial disclosures without awaiting a discovery request, including names of witnesses, documents supporting claims or defenses, damage calculations, and insurance agreements. Parties must supplement or correct prior disclosures and responses in a timely manner.

Expert witness disclosures under Rule 26(a)(2) require detailed written reports containing the expert’s opinions, qualifications, and compensation. Expert reports must be prepared by the expert and disclose all opinions and their bases. The expert may not offer opinions at trial that were not disclosed in the report.

Discovery in Criminal Cases

Criminal discovery differs from civil discovery, being more limited on both sides. Under Brady v. Maryland (1963), prosecutors must disclose material exculpatory evidence favorable to the defense. Brady material includes evidence that impeaches government witnesses, exculpatory forensic evidence, and information suggesting that someone else committed the crime.

Rule 16 of the Federal Rules of Criminal Procedure requires disclosure of defendant’s statements, prior criminal record, documents, and expert witnesses. The Jencks Act and Rule 26.2 require disclosure of witness statements after direct examination. Criminal discovery remains less extensive than civil discovery, reflecting the constitutional protections afforded to criminal defendants and the government’s interest in protecting sensitive information.
