Discovery

/dɪˈskʌvəri/
ProcedureLegal Rule: Federal Rules of Civil Procedure 26-37; Federal Rules of Criminal Procedure 16 (criminal discovery)

Definition

Discovery is the pretrial process by which parties obtain information and evidence from each other and from third parties. It includes interrogatories (written questions), requests for production of documents, requests for admission, depositions, physical and mental examinations, and subpoenas to non-parties. Discovery is governed by the principle of proportionality — the burden and expense must be proportional to the needs of the case.

Step-by-Step Process

1

Initial Disclosures

Both parties exchange basic information including witness lists, document inventories, and damage calculations within 14 days of the discovery conference.

2

Written Discovery

Parties serve interrogatories (written questions), requests for production of documents, and requests for admissions to the opposing side.

3

Depositions

Attorneys conduct sworn oral examinations of witnesses and parties, creating a transcript that can be used at trial.

4

Expert Discovery

Parties disclose expert witnesses, exchange expert reports, and conduct expert depositions.

5

Discovery Disputes

If parties disagree about discovery obligations, they file motions to compel or motions for protective orders with the court.

6

Discovery Cutoff

All discovery must be completed by the court-ordered deadline, typically 30 days before the pretrial conference.

In the Courtroom

Discovery is the backbone of American litigation and typically consumes the majority of time and expense in a case. The scope of discovery is broad: parties may obtain any non-privileged matter relevant to a party's claims or defenses, proportional to the needs of the case. Discovery begins after the parties' Rule 26(f) conference and the issuance of a scheduling order. Disputes about discovery — over relevance, privilege, proportionality, or compliance — are resolved through motions to compel or motions for protective orders. Sanctions for discovery abuse can range from monetary penalties to adverse inference instructions to default judgment in extreme cases.

Examples

1

Attorney: "We serve these interrogatories requiring the defendant to identify all persons with knowledge of the contract negotiations, all documents related to the transaction, and the factual basis for each affirmative defense." — Standard written discovery.

2

Judge: "The motion to compel is granted. The defendant shall produce all responsive documents within 14 days. The defendant's objections based on relevance are overruled — compensation data is relevant to the plaintiff's disparate pay claim and proportional to the needs of this case."

3

Attorney: "We request a Rule 30(b)(6) deposition of the corporation on the topic of its document retention policies. The corporation must designate a witness prepared to testify on its behalf regarding this subject."

Common Mistakes

Students often assume that relevance in discovery is the same as relevance for admissibility at trial. Discovery relevance is broader — information need not be admissible to be discoverable, so long as it appears reasonably calculated to lead to the discovery of admissible evidence and is proportional to the case needs.

Federal vs. State Differences

Federal discovery under FRCP 26 requires mandatory initial disclosures without a request, which many state courts do not require. Federal courts also impose proportionality limits and presumptive caps on depositions (10 per side) and interrogatories (25).

Landmark Cases

Hickman v. Taylor(1947)

Hickman v. Taylor, 329 U.S. 495 (1947)

Established the work-product doctrine, holding that materials prepared by an attorney in anticipation of litigation are generally protected from discovery, particularly opinion work product reflecting mental impressions and legal theories.

Zubulake v. UBS Warburg LLC(2003)

Zubulake v. UBS Warburg LLC, 220 F.R.D. 212 (S.D.N.Y. 2003)

Created a landmark cost-shifting framework for electronic discovery and established the duty to preserve electronically stored information once litigation is reasonably anticipated.

Seattle Times Co. v. Rhinehart(1984)

Seattle Times Co. v. Rhinehart, 467 U.S. 20 (1984)

Held that protective orders restricting dissemination of information obtained through discovery do not offend the First Amendment, because discovery is a matter of legislative grace rather than constitutional right.

Frequently Asked Questions

What types of discovery methods are available in federal court?

Federal Rule 26 authorizes six discovery methods: interrogatories (written questions), requests for production of documents and electronically stored information, depositions (oral or written), requests for admissions, physical and mental examinations, and subpoenas to non-parties. Each method serves different strategic purposes and has distinct procedural requirements.

What is the duty to preserve evidence during discovery?

Once litigation is reasonably anticipated, parties have a duty to preserve relevant evidence, including electronically stored information. Failure to preserve can result in spoliation sanctions under Rule 37(e), ranging from adverse inference instructions to case-dismissing sanctions. A litigation hold notice should be issued to all custodians of potentially relevant documents.

What privileges protect information from discovery?

The attorney-client privilege protects confidential communications between attorney and client for legal advice. The work-product doctrine protects materials prepared in anticipation of litigation. Other privileges include spousal privilege, physician-patient privilege, and the Fifth Amendment privilege against self-incrimination. Privileges must be asserted through a privilege log under Rule 26(b)(5).
