When a witness uses a writing or other item to refresh memory while testifying, an adverse party is entitled to have such writing or other item produced at the hearing, to inspect it, to cross-examine the witness thereon, and to introduce it, or, in the case of a writing, to introduce those portions which relate to the testimony of the witness, in evidence.
If it is claimed that the writing contains matters not related to the subject matter of the testimony, the judge shall examine the writing in camera, excise any portions not so related, and order delivery of the remainder to the party entitled thereto. Any portion withheld over objection shall be preserved and made available to the appellate court in the event of an appeal.
If a writing or other item is not produced or delivered pursuant to order under this section, the testimony of the witness concerning those matters shall be stricken.
