INSTRUCTIONS

1. Separate Answers Required. Each Interrogatory must be answered separately and fully in writing. Restate each Interrogatory in full immediately before the corresponding answer. Pursuant to Mont. R. Civ. P. 33(b)(3), each interrogatory must, to the extent it is not objected to, be answered separately and fully in writing under oath. (Rule 33(b)(1) identifies who must answer — the party, or for an entity any officer or agent, who must furnish the information available to the party.) Under Mont. R. Civ. P. 33(b)(5), the person who makes the answers must sign them, and the attorney who objects must sign any objections.

2. Oath Requirement. All answers must be made under oath and signed by the party answering, not merely by counsel. Mont. R. Civ. P. 33(b)(1).

3. Privilege or Protection. If any information is withheld based on a claim of attorney-client privilege, work-product protection, or any other privilege or immunity, Defendant must: (a) expressly state that information is being withheld; (b) identify the nature of the privilege or protection claimed; and (c) provide a privilege log or equivalent withholding description that complies with Mont. R. Civ. P. 26(b)(6), describing the nature of the documents, communications, or tangible things not produced in a manner sufficient to enable Plaintiff and the Court to assess the claim.

5. Objections. If Defendant objects to any Interrogatory, the grounds for objecting must be stated with specificity. Mont. R. Civ. P. 33(b)(4). If an objection is asserted as to part of an Interrogatory, answer the remainder to the extent not objectionable. Any ground not stated in a timely objection is waived unless the court, for good cause, excuses the failure.

6. Time Frame. Unless an Interrogatory specifies otherwise, the relevant time period is from [__/__/____] through the present.

7. Construction. The terms "and" and "or" shall be construed conjunctively and disjunctively to make each Interrogatory inclusive rather than exclusive. The singular includes the plural and vice versa.

PRACTICE NOTES

Montana-Specific Discovery Rules

3. Contention Interrogatories. Under Mont. R. Civ. P. 33(a)(2), an interrogatory is not objectionable merely because it asks for an opinion or contention that relates to fact or the application of law to fact. However, the court may order that such interrogatories need not be answered until after designated discovery is complete or until a pretrial conference.

4. Objection Procedures. Objections must be stated with specificity. Mont. R. Civ. P. 33(b)(4). Boilerplate objections are disfavored. Any ground for objection not stated in a timely objection is waived unless the court, for good cause, excuses the failure.

5. Motion to Compel. Under Mont. R. Civ. P. 37(a), if a party fails to answer an interrogatory, the propounding party may move for an order compelling answers. The motion must include a certification that the movant has in good faith conferred or attempted to confer with the party failing to respond.

6. Sanctions. Mont. R. Civ. P. 37(b) authorizes sanctions for failure to comply with a discovery order, including:

• ☐ Establishing designated facts as admitted
• ☐ Refusing to allow the disobedient party to support or oppose designated claims or defenses
• ☐ Striking pleadings in whole or in part
• ☐ Staying further proceedings until compliance
• ☐ Dismissing the action or rendering default judgment
• ☐ Contempt of court
• ☐ Award of reasonable expenses, including attorney's fees

7. Meet and Confer Requirement. Mont. R. Civ. P. 26(f) requires the parties to confer as soon as practicable and at least 21 days before a scheduling conference is held or a scheduling order is due. The discovery plan may affect the timing and scope of interrogatories.

8. Protective Orders. If sensitive information (e.g., trade secrets, medical records, financial data) is anticipated, consider seeking a stipulated protective order under Mont. R. Civ. P. 26(c) before serving interrogatories.

9. Scope and mandatory limitations — Montana does NOT apply federal proportionality. Mont. R. Civ. P. 26(b)(1) retains the pre-2015 formulation: discovery may be had of any non-privileged matter relevant to any party's claim or defense, and "[t]he information sought need not be admissible at the trial if the discovery appears reasonably calculated to lead to the discovery of admissible evidence." The 2015 federal amendment that made discovery "proportional to the needs of the case" an element of the scope of discovery was not adopted in Montana; do not plead it as the Montana standard. The operative Montana constraint is Mont. R. Civ. P. 26(b)(2)(C), under which the court must, on motion or on its own, limit the frequency or extent of discovery if (i) it is unreasonably cumulative or duplicative, or obtainable from a more convenient, less burdensome, or less expensive source; (ii) the party seeking discovery has had ample opportunity to obtain the information; or (iii) the burden or expense of the proposed discovery outweighs its likely benefit, considering the needs of the case, the amount in controversy, the parties' resources, the importance of the issues at stake, and the importance of the discovery in resolving the issues. Rule 26(g)(1)(C) separately requires the signer to certify that a request is neither unreasonable nor unduly burdensome or expensive on comparable factors.
