Okla. Stat. tit. 20, § 20-106.5

Any transcript of notes, duly certified as correct by the

reporter who took the evidence, and filed with the clerk of the

court in which the cause was tried, shall be admissible as evidence

in all cases, of like force and effect, as testimony taken in the

cause by deposition, and subject to the same objection, a transcript

of said notes may be incorporated into any appellate record. If any

reporter ceases to be the official reporter of the court, and

thereafter makes a transcript of the notes taken by him while acting

as official reporter, he shall swear to the transcript as true and

correct and when so verified, the transcript shall have the same

force and effect as if certified while he was an official reporter.

A transcript of the notes of any reporter of the State Industrial

Court, when certified or verified by such reporter who took the

evidence in any hearing before such Industrial Court or any official

thereof in any proceedings pending before such court, shall have the

same force and effect as a transcript by a court reporter above

mentioned, when such transcript is offered as a deposition in

evidence in any subsequent trial or proceedings before any court of

record wherein the parties are the same as the parties who took part

in the proceedings before the State Industrial Court; that is, the

same parties as the claimant and respondent before the Industrial

Court; provided that, if such party, who is claimant before the

Industrial Court, is deceased, then the provisions hereof shall

apply if the subsequent action is by the personal representative of

such deceased party in an action for wrongful death.
