Okla. Stat. tit. 12, § 12-2612: Writing used to refresh memory

If a witness uses a record or object to refresh the witness’s

memory either while testifying or before testifying, the court shall

allow an adverse party to have the record or object produced at the

hearing, to inspect it, to cross-examine the witness thereon and to

introduce in evidence those portions which relate to the testimony

of the witness. If it is claimed by an opposing party that the

record or object contains matters not related to the subject matter

of the testimony, the court shall examine the record or object in

chambers, excise any portions not so related, and order delivery of

the remainder to the party entitled thereto. Any portion withheld

over objections shall be preserved and made available to the

appellate court in the event of an appeal. If a record or object is

not produced, made available for inspection, or delivered pursuant

to order, the court shall make any order justice requires, but in

criminal cases if the prosecution elects not to comply, the order

shall be an order striking the testimony or declaring a mistrial.
