23A-12-6. (Rule 15(e)) Circumstances permitting use of deposition at trial--Use for impeachment--Parts of deposition used. At a trial or any hearing, a part or all of a deposition, so far as otherwise admissible under the rules of evidence, may be used if it appears:
(1) That a witness is dead;
(2) That the witness is out of the state, unless it appears that the absence of the witness was procured by the party offering the deposition;
(3) That the witness is unable to attend or testify because of sickness or infirmity; or
(4) That the witness is confined in jail or prison outside the state.
When a deposition has once been taken, it may be read in any stage of the same action and on any trial thereof. Any deposition may also be used by any party for the purpose of contradicting or impeaching the testimony of the deponent as a witness. If only a part of a deposition is offered in evidence by a party, an adverse party may require him to offer all of it which is relevant to the part offered, and any party may offer other parts.
