Rule 611 - Mode and order of interrogation and presentation(a) Control by court. The court shall exercise reasonable control over the mode and order of interrogating witnesses and presenting evidence so as to: (1) Make the interrogation and presentation effective for the ascertainment of the truth; (2) Avoid needless consumption of time; and (3) Protect witnesses from harassment or undue embarrassment. (b) Scope of cross-examination. A witness may be cross-examined on any matter relevant to any issue in the case, including credibility. In the interests of justice, the trial court may limit cross-examination with respect to matters not testified to on direct examination. (c) Leading questions. Leading questions should not be used on the direct examination of a witness except as may be necessary to develop the witness' testimony. Ordinarily leading questions should be permitted on cross-examination, but only upon the subject matter of the direct examination. When a party calls a hostile witness, an adverse party, or a witness identified with an adverse party, interrogation may be by leading questions. Enacted 1990 Ky.
