Rule 613

(a) Showing or Disclosing the Statement During Examination. When examining a witness about the witness’s prior statement, a party need not show it or disclose its contents to the witness. But the party must, on request, show it or disclose its contents to an adverse party’s attorney.

(b) Extrinsic Evidence of a Prior Inconsistent Statement. Extrinsic evidence of a witness’s prior inconsistent statement is admissible only if the witness is given an opportunity to explain or deny the statement and an adverse party is given an opportunity to examine the witness about it, or if justice so requires. This subdivision (b) does not apply to an opposing party’s statement under Rule 801(d)(2).

Excerpt from Advisory Committee Notes:

he Queen's Case, 2 Br. & B. 284, 129 Eng. Rep. 976 (1820), laid down the requirement that a cross-examiner, prior to questioning the witness about his own prior statement in writing, must first show it to the witness. . . . The rule abolishes this useless impediment, to cross-examination. . . . Both oral and written statements are included.

The provision for disclosure to counsel is designed to protect against unwarranted insinuations that a statement has been made when the fact is to the contrary.
