EVIDENCE Rule 607. Credibility and Neutralization
Except as otherwise provided by Rules 405 and 608, for the purpose of impairing or supporting the credibility of a witness, any party including the party calling the witness may examine the witness and introduce extrinsic evidence relevant to the issue of credibility, except that the party calling a witness may not neutralize the witness' testimony by a prior contradictory statement unless the statement is in a form admissible under Rule 803(a)(1) or the judge finds that the party calling the witness was surprised. A prior consistent statement shall not be admitted to support the credibility of a witness except to rebut an express or implied charge against the witness of recent fabrication or of improper influence or motive and except as otherwise provided by the law of evidence.
