(B) it is used to the extent it would be admissible under the Federal Rules of Evidence if the deponent were present and testifying; and
(C) the use is allowed by Rule 32(a)(2) through (8).
(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 30(b)(6) or 31(a)(4).
(4) Unavailable Witness. A party may use for any purpose the deposition of a witness, whether or not a party, if the court finds:
(B) that the witness is more than 100 miles from the place of hearing or trial or is outside the United States, unless it appears that the witness’s 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’s 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.
(B) Unavailable Deponent; Party Could Not Obtain an Attorney. A deposition taken without leave of court under the unavailability provision of Rule 30(a)(2)(A)(iii) 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.
(7) Substituting a Party. Substituting a party under Rule 25 does not affect the right to use a deposition previously taken.
(8) Deposition Taken in an Earlier Action. A deposition lawfully taken and, if required, filed 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 Federal Rules of Evidence.
(c) FORM OF PRESENTATION. Unless the court orders otherwise, a party must provide a transcript of any deposition testimony the party offers, but may provide the court with the testimony in nontranscript form as well. On any party’s request, deposition testimony offered in a jury trial for any purpose other than impeachment must be presented in nontranscript form, if available, unless the court for good cause orders otherwise.
(d) WAIVER OF OBJECTIONS.
(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:
(B) promptly after the basis for disqualification becomes known or, with reasonable diligence, could have been known.
(B) Objection to an Error or Irregularity. An objection to an error or irregularity at an oral examination is waived if:
(ii) it is not timely made during the deposition.
