Discovery Scope (Rule 26)

Federal Rule of Civil Procedure 26 establishes the general framework for discovery in federal litigation. Under Rule 26(b)(1), 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' relative access to relevant information, the parties' resources, the importance of the discovery in resolving the issues, and whether the burden or expense of the proposed discovery outweighs its likely benefit.

The 2015 amendments to Rule 26 elevated proportionality from a limitation to a core component of the relevance standard, reflecting the growing concern over the cost and burden of modern discovery, particularly electronic discovery. Information need not be admissible in evidence to be discoverable, but it must be relevant to a claim or defense actually pleaded in the case, not merely relevant to the subject matter of the action (a change from the earlier, broader formulation).

Rule 26(a) requires initial disclosures without awaiting a discovery request. Parties must identify individuals likely to have discoverable information, provide copies or descriptions of relevant documents, compute damages, and identify insurance agreements. These disclosures must be made within 14 days of the Rule 26(f) conference unless otherwise stipulated or ordered. Rule 26(b)(3) codifies the work product doctrine, and Rule 26(b)(5) establishes procedures for asserting privilege. Rule 26(c) authorizes protective orders to limit discovery for good cause, including to protect trade secrets, confidential information, or to prevent annoyance, embarrassment, oppression, or undue burden.
