4.1 Discovery, Disclosure & Sanctions

4.1 Discovery, Disclosure & Sanctions

Discovery in federal civil litigation is designed to eliminate unfair surprises at trial, narrow the disputed issues, and encourage early settlement by giving all parties access to the relevant facts. The modern discovery framework under Rules 26 through 37 balances broad disclosure against the burdens of cost and delay, establishing strict limits on discovery devices, robust privileges, and severe sanctions for non-compliance.

1. Scope of Discovery and Proportionality (Rule 26(b)(1))

Under Federal Rule of Civil Procedure 26(b)(1), parties may obtain discovery regarding:

Any non-privileged matter that is relevant to any party's claim or defense and proportional to the needs of the case.

The Proportionality Standard

The 2015 amendments to Rule 26 restored proportionality to the core definition of discovery scope. In determining whether requested discovery is proportional, courts consider six balanced factors:

1. The importance of the issues at stake in the action;
2. The amount in controversy;
3. The parties' relative access to relevant information;
4. The parties' resources;
5. The importance of the discovery in resolving the issues; and
6. Whether the burden or expense of the proposed discovery outweighs its likely benefit.

Admissibility vs. Discoverability

A critical MBE rule: Information within the scope of discovery need not be admissible in evidence to be discoverable. For example, hearsay evidence or settlement discussions that might be inadmissible at trial under the Federal Rules of Evidence are fully discoverable if they are non-privileged, relevant to a claim or defense, and proportional to the needs of the case.

2. Privileges and the Work Product Doctrine

Evidentiary privileges and the work product doctrine represent the two primary substantive limitations on the scope of discovery.

Attorney-Client Privilege

The attorney-client privilege protects confidential communications between a client and an attorney (or the attorney's agents) made for the purpose of seeking or providing professional legal advice. Unlike work product, the privilege is not overcome by a showing of need; it is lost through waiver (such as voluntary disclosure to third parties) or under the crime-fraud exception.

The Work Product Doctrine (Rule 26(b)(3))

Originating in Hickman v. Taylor (1947) and codified in Rule 26(b)(3), the work product doctrine protects documents and tangible things prepared in anticipation of litigation or for trial by or for another party or its representative (including the party's attorney, consultant, surety, indemnitor, insurer, or agent).

The doctrine distinguishes between two tiers of work product:

+-----------------------------------------------------------------------------------+
|                         THE WORK PRODUCT DOCTRINE SPECTRUM                        |
+-----------------------------------------------------------------------------------+
| Ordinary / Fact Work Product                                                      |
| - Witness interview summaries, accident reports, investigator memos, photographs.  |
| - STANDARD FOR DISCLOSURE: Discoverable ONLY upon showing:                        |
|   1. Substantial need for the materials to prepare the case; AND                  |
|   2. Inability to obtain their substantial equivalent by other means              |
|      without undue hardship (e.g., witness deceased, abroad, or hostile).        |
+-----------------------------------------------------------------------------------+
                                     vs.
+-----------------------------------------------------------------------------------+
| Opinion / Core Work Product                                                       |
| - Mental impressions, conclusions, opinions, or legal theories of an attorney     |
|   or other representative.                                                        |
| - STANDARD FOR DISCLOSURE: NEARLY ABSOLUTE PROTECTION. Even when fact work        |
|   product must be produced, Rule 26(b)(3)(B) directs courts to protect these      |
|   mental impressions; disclosure is rare (e.g., when they are directly at issue). |
+-----------------------------------------------------------------------------------+

The Privilege Log (Rule 26(b)(5))

A party withholding discoverable materials under a claim of privilege or work product must expressly claim the protection and provide a privilege log. The log must describe the nature of the documents, communications, or tangible things not produced in a manner that enables other parties to assess the claim without revealing the privileged or protected information itself.

---

3. Required Disclosures (Rule 26(a))

Rule 26(a) mandates three tiers of disclosures that parties must make automatically, without waiting for a formal discovery request from the opposing party.

Initial Disclosures (Rule 26(a)(1))

Unless exempt or otherwise ordered, each party must provide initial disclosures within 14 days after the Rule 26(f) conference. The disclosures must cover:

1. Witnesses: The name, address, and telephone number of each individual likely to have discoverable information—along with the subjects of that information—that the disclosing party may use to support its claims or defenses, unless solely for impeachment;
2. Documents and ESI: A copy or a description by category and location of all documents, electronically stored information (ESI), and tangible things that the disclosing party has in its possession, custody, or control and may use to support its claims or defenses, unless solely for impeachment;
3. Damages Computation: A computation of each category of damages claimed by the disclosing party, making available for inspection the underlying non-privileged evidentiary documents;
4. Insurance Agreements: Any insurance agreement under which an insurance business may be liable to satisfy all or part of a possible judgment or indemnify/reimburse payments.

Key Limitation: Parties are only required to disclose witnesses and documents that they may use to support their own claims or defenses. A party has no obligation under Rule 26(a)(1) to disclose damaging witnesses or unfavorable documents that it does not intend to use.

Expert Disclosures (Rule 26(a)(2))

A party must disclose the identity of any expert witness who may testify at trial. For retained experts, disclosure must include a detailed written report signed by the expert containing a complete statement of all opinions, the basis and reasons for them, facts/data considered, exhibits, qualifications, a 10-year list of publications, and a 4-year history of testimony and compensation. Expert disclosures must be made at least 90 days before trial, or within 30 days if solely to rebut opposing expert evidence.

Pretrial Disclosures (Rule 26(a)(3))

At least 30 days before trial, parties must disclose witness lists, deposition designations, and exhibit lists. An opposing party must serve objections within 14 days after service; failure to object waives all objections other than relevance under FRE 402 and 403.

+----------------------+---------------+-------------------+------------------------+

Interrogatories (Rule 33)

• Parties Only: Interrogatories can never be served on non-party witnesses.
• Numeric Cap: Presumptive limit of 25 written interrogatories, including all discrete subparts, unless stipulated by the parties or granted leave by the court.
• Responses: Must be answered under oath and signed by the responding party; objections must be signed by the attorney. Responses are due within 30 days after service.

Depositions (Rules 30, 31, and 45)

• Scope and Limits: May depose any person, including parties and non-parties. Presumptively limited to 10 depositions per side, with each deposition limited to one day of seven hours.
• Non-Party Subpoena (Rule 45): A deposition notice compels an opposing party to attend, but a non-party witness can only be compelled to appear and produce documents through a subpoena issued under Rule 45.
• Organizational Depositions (Rule 30(b)(6)): A party naming a corporation, partnership, or agency as a deponent must describe the matters for examination with reasonable particularity. The organization must then designate one or more officers, directors, or persons who consent to testify on its behalf regarding information known or reasonably available to the organization.

Physical and Mental Examinations (Rule 35)

• Court Order Required: Rule 35 is the only discovery device that requires prior court approval absent a stipulation.
• Two-Part Standard: The court will order an exam only if: (1) the physical or mental condition of a party (or person in the custody or legal control of a party) is in controversy; and (2) the moving party demonstrates good cause.

Requests for Admission (Rule 36)

• The 30-Day Admission Trap: Requests for admission allow a party to request that an opposing party admit the truth of facts, the application of law to fact, or the genuineness of documents. If the responding party fails to serve a written answer or objection within 30 days of service, the matter is automatically deemed admitted.
• Conclusively Established: Under Rule 36(b), a matter admitted is conclusively established for the pending action unless the court, on motion, permits withdrawal or amendment.

5. Duty to Supplement and Discovery Sanctions

The Duty to Supplement (Rule 26(e))

A party who has made initial disclosures or responded to interrogatories, requests for production, or requests for admission has an ongoing, mandatory duty to supplement or correct its disclosures or responses in a timely manner if the party learns that in some material respect the information disclosed is incomplete or incorrect.

• Automatic Exclusion (Rule 37(c)(1)): If a party fails to disclose or supplement information as required by Rule 26(a) or (e), the party is not allowed to use that information or witness to supply evidence on a motion, at a hearing, or at trial, unless the failure was substantially justified or harmless.

Motion to Compel and Two-Step Sanctions (Rule 37(a) & (b))

When a party fails to provide discovery or provides incomplete/evasive responses, discovery sanctions generally proceed in two distinct steps:

1. Step 1: Motion to Compel (Rule 37(a)): The discovering party must first file a motion to compel. The motion must include a certification that the movant has in good faith conferred or attempted to confer with the opposing party in an effort to resolve the dispute without court action. If granted, the court must award reasonable expenses and attorney fees incurred in making the motion, unless the opposing position was substantially justified.
2. Step 2: Violation of Court Order (Rule 37(b)): If the court orders discovery and the party disobeys the court order, the court may impose dispositive sanctions, including: directing that matters be taken as established, prohibiting the disobedient party from supporting claims or defenses, striking pleadings, dismissing the action in whole or in part, rendering a default judgment, or holding the party in contempt of court (contempt is not available for refusing to submit to a physical/mental exam).

Immediate Severe Sanctions (Rule 37(d)): If a party completely fails to appear for its own properly noticed deposition, or completely fails to serve any answers or objections to interrogatories or requests for production, no preliminary motion to compel is required; the court may immediately impose Rule 37(b) sanctions.

Spoliation of Electronically Stored Information (ESI) (Rule 37(e))

When ESI that should have been preserved in the anticipation or conduct of litigation is lost because a party failed to take reasonable steps to preserve it, and it cannot be restored or replaced through additional discovery:

• Prejudice Finding (Rule 37(e)(1)): If the court finds prejudice to another party, it may order measures no greater than necessary to cure the prejudice.
• Intent to Deprive Finding (Rule 37(e)(2)): Only upon an express finding that the party acted with the intent to deprive another party of the information's use in litigation may the court: (A) presume that the lost information was unfavorable; (B) instruct the jury that it may or must presume the information was unfavorable (adverse inference instruction); or (C) dismiss the action or enter a default judgment.

6. Timing, Conferences, Protective Orders, Experts, and Use at Trial

Timing and the Rule 26(f) Conference

• Discovery moratorium (Rule 26(d)(1)): A party may not seek discovery from any source before the parties have conferred under Rule 26(f), except in exempt proceedings, by stipulation, or by court order. Early Rule 34 requests may be delivered more than 21 days after service of the summons and complaint, but they are treated as served at the first Rule 26(f) conference (Rule 26(d)(2)).
• The conference: The parties must confer as soon as practicable—and at least 21 days before a scheduling conference is held or a scheduling order is due—to discuss claims, defenses, settlement, initial disclosures, and preservation, and to develop a discovery plan. They must submit a written report within 14 days after the conference.
• Contents of the plan (Rule 26(f)(3)): The plan states the parties' views on disclosures, subjects and timing of discovery, electronically stored information (ESI), limits on discovery, and privilege issues. Under amendments effective December 1, 2025, it must address the timing and method for complying with Rule 26(b)(5)(A)'s privilege-log requirement, along with any agreement for asserting privilege after production, such as an order under Federal Rule of Evidence 502.

Protective Orders and Limits

• Protective orders (Rule 26(c)): On motion with a certification of a good-faith attempt to confer, the court may, for good cause, protect a party or person from annoyance, embarrassment, oppression, or undue burden or expense—for example, by forbidding certain discovery, limiting its scope, specifying terms, sealing a deposition, or protecting trade secrets.
• ESI that is not reasonably accessible (Rule 26(b)(2)(B)): A party need not provide ESI from sources it identifies as not reasonably accessible because of undue burden or cost. If that showing is made, the court may still order discovery for good cause, subject to Rule 26(b)(2)(C) and conditions such as cost-shifting.
• Mandatory limits (Rule 26(b)(2)(C)): The court must limit discovery that is unreasonably cumulative or duplicative, obtainable from a more convenient or less burdensome source, sought by a party who already had ample opportunity to obtain it, or outside the scope of Rule 26(b)(1).
• Clawback (Rule 26(b)(5)(B)): If privileged material is produced, the producing party may notify the receiving party, which must promptly return, sequester, or destroy it and may not use or disclose it until the claim is resolved.

Experts (Rule 26(b)(4))

• A party may depose a testifying expert, but only after any required report is provided.
• Drafts of expert reports, and communications between a party's attorney and a retained testifying expert, are protected as work product, except for communications about the expert's compensation, facts or data the attorney provided and the expert considered, and assumptions the attorney provided and the expert relied on.
• Facts known and opinions held by a consulting expert who will not testify are discoverable only on a showing of exceptional circumstances making it impracticable to obtain the same information by other means.

Certification and Subpoenas

• Rule 26(g): Every disclosure and discovery request, response, or objection must be signed by an attorney (or an unrepresented party), certifying after reasonable inquiry that it is complete, correct, and not interposed for an improper purpose. A violation without substantial justification requires an appropriate sanction.
• Rule 45: A subpoena may command a nonparty to attend a deposition, hearing, or trial, or to produce documents, generally within 100 miles of where the person resides, is employed, or regularly transacts business in person. The issuing party must avoid imposing undue burden or expense on the person subpoenaed.

Using Depositions at Trial (Rule 32)

A deposition may be used against a party only if that party was present, represented, or had reasonable notice of it (Rule 32(a)(1)).
