Redirect Examination – the questioning of a witness by a party who called the witness after that witness has been subject to cross-examination. The purpose of redirect examination is to rebut or clarify any damaging testimony elicited on cross-examination.
In general, the redirect examination of a witness may extend to matters brought out on cross-examination, and ordinarily it should be limited to the scope of the cross-examination, although the court may permit it to go beyond the scope thereof
