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

(a) Using Depositions.
(1) In General. At a hearing, trial, or on an interlocutory proceeding, all or part of a deposition may be used against a party on these conditions:
(A) the party was present or represented at the taking of the deposition or had reasonable notice of it;
(B) it is used to the extent it would be admissible under the Idaho Rules of Evidence and these rules if the deponent were present and testifying; and
(C) the use is allowed by subsections (a)(2) through (8).
(2) Impeachment and Other Uses. Any party may use a deposition to contradict or impeach the testimony given by the deponent as a witness, or for any other purpose allowed by the Idaho Rules of Evidence and these rules.
(3) Deposition of Party, Agent, or Designee. An adverse party may use for any purpose the deposition of a party or anyone who, when deposed, was the party's officer, director, managing agent, or designee under Rule 412.
(4) Unavailable Witness. A party may use for any purpose the deposition of a witness, whether or not a party, if the court finds:
(A) that the witness is dead;
(B) that the witness is more than 100 miles from the place of hearing or trial or is outside the state of Idaho, unless it appears that the witness' absence was procured by the party offering the deposition;
(C) that the witness cannot attend or testify because of age, illness, infirmity, or imprisonment;
(D) that the party offering the deposition could not procure the witness' attendance by subpoena; or
(E) on motion and notice, that exceptional circumstances make it desirable, in the interest of justice and with due regard to the importance of live testimony in open court, to permit the deposition to be used.
(5) Limitations on Use.
(A) Deposition Taken on Short Notice. A deposition must not be used against a party who, having received less than 14 days' notice of the deposition, promptly moved for a protective order under Rules 404(a)(2) requesting that it not be taken or be taken at a different time or place, and this motion was still pending when the deposition was taken.
(B) Unavailable Deponent; Party Could Not Obtain an Attorney. A deposition taken without leave of court under the unavailability provision of Rule 412(a)(2)(B)(ii) must not be used against a party who shows that, when served with the notice, it could not, despite diligent efforts, obtain an attorney to represent it at the deposition.
(6) Using Part of a Deposition. If a party offers in evidence only part of a deposition, an adverse party may require the offeror to introduce other parts that in fairness should be considered with the part introduced, and any party may itself introduce any other parts.
(7) Substituting a Party. Substituting a party under I.R.C.P. Rule 25 does not affect the right to use a deposition previously taken.
(8) Deposition Taken in an Earlier Action. A deposition lawfully taken in any federal or state-court action may be used in a later action involving the same subject matter between the same parties, or their representatives or successors in interest, to the same extent as if taken in the later action. A deposition previously taken may also be used as allowed by the Idaho Rules of Evidence.
(b) Objections to Admissibility. Subject to I.R.C.P. Rule 32(d)(3), an objection may be made at a hearing or trial to the admission of any deposition testimony that would be inadmissible if the witness were present and testifying.
(c) Reserved.
(d) Waiver of Objections.
(1) To The Notice. An objection to an error or irregularity in a deposition notice is waived unless promptly served in writing on the party giving the notice.
(2) To the Officer's Qualification. An objection based on disqualification of the officer before whom a deposition is to be taken is waived if not made:
(A) before the deposition begins; or
(B) promptly after the basis for disqualification becomes known or, with reasonable diligence, could have been known.
(3) To the Taking of the Deposition.
(A) Objection to Competence, Relevance, or Materiality. An objection to a deponent's competence, or to the competence, relevance, or materiality of testimony, is not waived by a failure to make the objection before or during the deposition, unless the ground for it might have been corrected at that time.
(B) Objection to an Error or Irregularity. An objection to an error or irregularity at an oral examination is waived if:
(i) it relates to the manner of taking the deposition, the form of a question or answer, the oath or affirmation, a party's conduct, or other matters that might have been corrected at that time; and
(ii) it is not timely made during the deposition.
(C) Objection to a Written Question. An objection to the form of a written question under Rule 412 is waived if not served in writing on the party submitting the question within the time for serving responsive questions or, if the question is a recross-question, within 7 days after being served with it.
(4) To Completing and Returning the Deposition. An objection to how the officer transcribed the testimony, or prepared, signed, certified, sealed, endorsed, sent, or otherwise dealt with the deposition, is waived unless a motion to suppress is made promptly after the error or irregularity becomes known or, with reasonable diligence, could have been known.

Rule History

(Adopted March 29, 2021, effective July 1, 2021.)

Plain-English Summary

Rule 415 governs getting a deposition into evidence.

The threshold

All or part of a deposition may be used against a party if that party was present or represented, or had reasonable notice; it is used to the extent it would be admissible under the Idaho Rules of Evidence and these rules with the deponent testifying; and the use is allowed by one of the categories below. Remember that Rule 102(b)(2) will often have replaced the hearsay rules with the relaxed standard.

Three routes to use

Impeachment: any party may use a deposition to contradict or impeach the deponent's testimony, or for any other purpose the rules allow.

A party's own deposition: an adverse party may use for any purpose the deposition of a party, or of anyone who was a party's officer, director, managing agent, or Rule 412 designee when deposed.

An unavailable witness: a deposition may be used for any purpose on a court finding that the witness is dead; is more than 100 miles from the hearing or outside Idaho — unless the absence was procured by the offering party; cannot attend because of age, illness, infirmity, or imprisonment; could not be subpoenaed; or, on motion and notice, that exceptional circumstances make it desirable in the interest of justice with due regard to the importance of live testimony in open court.

Two limitations

A deposition must not be used against a party who received less than 14 days' notice and promptly moved for a protective order that was still pending when it was taken. Nor against a party who shows that, when served with notice of an early deposition taken under the unavailability exception, it could not despite diligent efforts obtain an attorney.

Completeness, substitution, and earlier actions

If a party offers part of a deposition, an adverse party may require the offeror to introduce other parts that in fairness should be considered with it, and any party may introduce other parts itself. Substituting a party under I.R.C.P. Rule 25 does not affect the right to use a deposition already taken. A deposition lawfully taken in any federal or state action may be used in a later action involving the same subject matter between the same parties or their representatives or successors, to the same extent as if taken in the later action.

Which objections survive silence

Objections to a deponent's competence, or to the competence, relevance or materiality of testimony are not waived by failing to raise them at the deposition — unless the ground might have been corrected at that time.

Everything curable is waived if not raised then: an objection to an error or irregularity at the oral examination relating to the manner of taking, the form of a question or answer, the oath, or a party's conduct. Objections to the notice are waived unless promptly served in writing; to the officer's qualification, unless made before the deposition begins or promptly after the basis is known; to the form of a written question, unless served within the time for responsive questions or within 7 days for a recross-question; and to how the officer transcribed or handled the deposition, unless a motion to suppress is made promptly.

Frequently Asked Questions

When can I use a deposition instead of live testimony?

Rule 415(a)(4) allows it on a court finding that the witness is dead, is more than 100 miles from the hearing or outside Idaho unless the absence was procured by the offering party, cannot attend because of age, illness, infirmity or imprisonment, could not be subpoenaed, or that exceptional circumstances make it desirable in the interest of justice.

Can I use the other party's deposition for any purpose?

Yes. Rule 415(a)(3) allows an adverse party to use for any purpose the deposition of a party or anyone who was the party's officer, director, managing agent, or Rule 412 designee when deposed.

If I did not object at the deposition, is the objection lost?

It depends. Rule 415(d)(3)(A) preserves objections to competence, relevance and materiality unless the ground might have been corrected at the time. Rule 415(d)(3)(B) waives objections to the manner of taking, the form of a question or answer, the oath, or a party's conduct if not timely made during the deposition.

Can a deposition taken on short notice be used against me?

Rule 415(a)(5)(A) bars use against a party who received less than 14 days' notice and promptly moved for a protective order under Rule 404(a)(2) that was still pending when the deposition was taken.

Can the other side read only the helpful part?

No. Rule 415(a)(6) allows an adverse party to require the offeror to introduce other parts that in fairness should be considered with the part introduced, and allows any party to introduce other parts.

Can a deposition from an earlier case be used?

Rule 415(a)(8) allows a deposition lawfully taken in any federal or state-court action to be used in a later action involving the same subject matter between the same parties, or their representatives or successors in interest, to the same extent as if taken in the later action.
