Text sizeJump to: (a) (b) (c) (d) (e) (f)

(a) Motion for an order compelling disclosure or discovery.
(1) In general. On notice to other parties and all affected persons, a party may move for an order compelling disclosure or discovery. The motion must include a certification that the movant has in good faith conferred or attempted to confer with the person or party failing to make disclosure or discovery in an effort to obtain it without court action.
(2) Appropriate court. A motion for an order to a party must be made in the court where the action is pending. A motion for an order to a nonparty must be made in the court where the discovery is or will be taken if outside of Idaho.
(3) Specific motions.
(A) To compel a discovery response. A party seeking discovery may move for an order compelling an answer, designation, production, or inspection. This motion may be made if:
(i) a deponent fails to answer a question asked under Rule 30 or 31;
(ii) a corporation or other entity fails to make a designation under Rule 30(b)(6) or 31(a)(4);
(iii) a party fails to answer an interrogatory submitted under Rule 33; or
(iv) a party fails to respond that inspection will be permitted, or fails to permit inspection, as requested under Rule 34.
(B) Related to a deposition. When taking an oral deposition, the party asking a question may complete or adjourn the examination before moving for an order.
(4) Evasive or incomplete disclosure, answer, or response. For purposes of this subdivision (a), an evasive or incomplete disclosure, answer, or response must be treated as a failure to disclose, answer, or respond.
(5) Payment of expenses; Protective orders.
(A) If the motion is granted (or discovery is provided after filing). If the motion is granted, or if the requested discovery is provided after the motion was filed, the court must, after giving an opportunity to be heard, require the party or deponent whose conduct necessitated the motion, the party or attorney advising that conduct, or both to pay the movant's reasonable expenses incurred in making the motion, including attorney's fees. But the court must not order this payment if:
(i) the movant filed the motion before attempting in good faith to obtain the disclosure or discovery without court action;
(ii) the opposing party's nondisclosure, response, or objection was substantially justified; or
(iii) other circumstances make an award of expenses unjust.
(B) If the motion is denied. If the motion is denied, the court may issue any protective order authorized under Rule 26(c) and must, after giving an opportunity to be heard, require the movant, the attorney filing the motion, or both to pay the party or deponent who opposed the motion its reasonable expenses incurred in opposing the motion, including attorney's fees. But the court must not order this payment if the motion was substantially justified or other circumstances make an award of expenses unjust.
(C) If the motion is granted in part and denied in part. If the motion is granted in part and denied in part, the court may issue any protective order authorized under Rule 26(c) and may, after giving an opportunity to be heard, apportion the reasonable expenses for the motion.
(b) Failure to comply with a court order.
(1) Sanctions where the deposition is taken. If the court where the discovery outside of Idaho is taken orders a deponent to be sworn or to answer a question and the deponent fails to obey, the failure may be treated as contempt of either the court where the discovery is taken or the court where the action is pending.
(2) Sanctions where the action is pending.
(A) For not obeying a discovery order. If a party or a party's officer, director, or managing agent, or a witness designated under Rule 30(b)(6) or 31(a)(4), fails to obey an order to provide or permit discovery, including an order under Rule 35, or 37(a), the court where the action is pending may issue further just orders. They may include the following:
(i) directing that the matters embraced in the order or other designated facts be taken as established for purposes of the action, as the prevailing party claims;
(ii) prohibiting the disobedient party from supporting or opposing designated claims or defenses, or from introducing designated matters in evidence;
(iii) striking pleadings in whole or in part;
(iv) staying further proceedings until the order is obeyed;
(v) dismissing the action or proceeding in whole or in part;
(vi) rendering a default judgment against the disobedient party; or
(vii) treating as contempt of court the failure to obey any order except an order to submit to a physical or mental examination and initiating contempt proceedings.
(B) For not producing a person for examination. If a party fails to comply with an order under Rule 35(a) requiring it to produce another person for examination, the court may issue any of the orders listed in Rule 37(b)(2)(A)(i)-(vi), unless the disobedient party shows that it cannot produce the other person.
(C) Payment of expenses. Instead of or in addition to the orders above, the court must order the disobedient party, the attorney advising that party, or both to pay the reasonable expenses, including attorney's fees, caused by the failure, unless the failure was substantially justified or other circumstances make an award of expenses unjust.
(c) Failure to disclose, to supplement an earlier response, or to admit.
(1) Failure to disclose or supplement. If a party fails to supplement discovery responses when required or fails to comply with a disclosure requirement ordered by the court pursuant to a Rule 16 scheduling or pre-trial order, the party is not allowed to use that information or witness to supply evidence on a motion, at a hearing, or at a trial, unless the failure was substantially justified or is harmless. In addition to or instead of this sanction, the court, on motion and after giving an opportunity to be heard:
(A) may order payment of the reasonable expenses, including attorney's fees, caused by the failure;
(B) may impose other appropriate sanctions, including any of the orders listed in Rule 37(b)(2)(A)(i)-(vi).
(2) Failure to admit. If a party fails to admit what is requested under Rule 36 and if the requesting party later proves a document to be genuine or the matter true, the requesting party may move that the party who failed to admit pay the reasonable expenses, including attorney's fees, incurred in making that proof. The court must so order unless:
(A) the request was held objectionable under Rule 36(a);
(B) the admission sought was of no substantial importance;
(C) the party failing to admit had a reasonable ground to believe that it might prevail on the matter; or
(D) there was other good reason for the failure to admit.
(d) Party's failure to attend its own deposition, serve answers to interrogatories, or respond to a request for production or for inspection.
(1) In general.
(A) Motion; Grounds for sanctions. The court where the action is pending may, on motion, order sanctions if:
(i) a party or a party's officer, director, or managing agent, or a person designated under Rule 30(b)(6) or 31(a)(4), fails, after being served with proper notice, to appear for that person's deposition; or
(ii) a party, after being properly served with interrogatories under Rule 33 or a request for production or inspection under Rule 34, fails to serve its answers, objections, or written response.
(B) Certification. A motion for sanctions for failing to answer or respond must include a certification that the movant has in good faith conferred or attempted to confer with the party failing to act in an effort to obtain the answer or response without court action.
(2) Unacceptable excuse for failing to act. A failure described in Rule 37(d)(1)(A) is not excused on the ground that the discovery sought was objectionable, unless the party failing to act has a pending motion for a protective order under Rule 26(c).
(3) Types of sanctions. Sanctions may include any of the orders listed in Rule 37(b)(2)(A)(i)--(vi). Instead of or in addition to these sanctions, the court must require the party failing to act, the attorney advising that party, or both to pay the reasonable expenses, including attorney's fees, caused by the failure, unless the failure was substantially justified or other circumstances make an award of expenses unjust.
(e) Failure to provide electronically stored information. Absent exceptional circumstances, a court may not impose sanctions under these rules on a party for failing to provide electronically stored information lost as a result of the routine, good-faith operation of an electronic information system.
(f) General sanctions; Catch-all. In addition to the sanctions provided for in this rule for violation of discovery procedures, any court may impose sanctions or conditions, or assess attorney fees, costs or expenses against a party or the attorney advising that party for failure to comply with an order made pursuant to these rules.

Plain-English Summary

Discovery only works if both sides play along, and Rule 37 backs it up with consequences. A party who isn't getting the discovery it's entitled to can move to compel an answer, a designation, production, or an inspection, but only after certifying it tried in good faith to work things out without court intervention. The motion goes to the court where the case is pending, or, for discovery happening outside Idaho, to the court where that discovery is taken. Specific grounds include a deponent who won't answer a question, an entity that won't designate a Rule 30(b)(6) or 31(a)(4) witness, a party that won't answer an interrogatory, or a party that won't permit an inspection — and an evasive or incomplete answer counts as no answer at all. Whichever way the motion comes out, someone typically pays: if it's granted, or the discovery shows up only after the motion was filed, the resisting party or its attorney generally owes the movant's reasonable expenses, including attorney's fees, unless the motion was filed too hastily, the resistance was substantially justified, or some other circumstance makes an award unjust. If it's denied, that same expense-shifting runs the other way, and if the motion is granted in part and denied in part, the court can apportion expenses and issue a protective order.

Disobeying an actual court order raises the stakes further. If the discovery happened outside Idaho and the deponent won't answer as ordered, that's treated as contempt of either court. Where the action is pending, a party who defies a discovery order faces a menu of sanctions: facts taken as established, evidence or defenses barred, pleadings struck, the case stayed, the case dismissed, a default judgment entered, or contempt proceedings — plus, unless the failure was substantially justified, a mandatory order to pay the resulting expenses and fees. A separate, related set of consequences applies without needing a prior order at all: failing to supplement a discovery response or comply with a court-ordered disclosure blocks the use of that information or witness later, unless the failure was substantially justified or harmless, and failing to admit something under Rule 36 that later gets proven true or genuine can mean paying the cost of proving it up. A party who skips its own deposition, or ignores interrogatories or a request for production entirely, faces the same range of sanctions on motion, and can't excuse it by claiming the discovery was objectionable unless a protective order motion is pending. One safe harbor exists: a court generally can't sanction a party for losing electronically stored information through the routine, good-faith operation of an ordinary information system. And a catch-all provision backs up every other part of the rule, letting the court impose sanctions or fees for violating any order made under these discovery rules.

Frequently Asked Questions

What has to happen before I can file a motion to compel?

Rule 37(a)(1) requires a certification that the movant tried in good faith to work out the dispute with the other side before turning to the court. Skipping that step can cost the movant its expenses even if the motion is otherwise granted.

What sanctions can a court impose if a party disobeys a discovery order?

A wide range: treating disputed facts as established, barring the disobedient party from supporting or opposing certain claims or evidence, striking pleadings, staying the case, dismissing it, entering a default judgment, or holding the party in contempt. The court must also order payment of the resulting expenses and attorney's fees unless the failure was substantially justified or an award would be unjust.

Do I need a court order already in place before sanctions apply for skipping a deposition or ignoring interrogatories?

No. Rule 37(d) lets the court sanction a party who fails to appear for its own deposition or fails to answer interrogatories or a request for production, without any earlier order being violated. Claiming the discovery was objectionable doesn't excuse the failure unless a protective order motion is pending.

What happens if I fail to admit something under Rule 36 that turns out to be true?

The requesting party can move for the reasonable expenses, including attorney's fees, spent proving the matter true or the document genuine. The court must order payment unless the request was objectionable, of no real importance, or the party had a reasonable basis to believe it would prevail, or some other good reason explains the refusal.

Can a party be sanctioned for losing electronically stored information?

Generally not, if the loss resulted from the routine, good-faith operation of an ordinary electronic information system. Rule 37(e) reserves sanctions for that scenario to exceptional circumstances.
