ARTICLE VI. WITNESSES
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.
(1) Party Witness. A party may be cross-examined on any matter relevant to any issue in the case, including credibility. In the interest of justice, the judge may limit cross-examination with respect to matters not testified to on direct examination.
(2) Non-Party Witnesses. Cross-examination should be limited to the subject matter of the direct examination and matters affecting the credibility of the non-party witness. The court may, in the exercise of discretion, permit inquiry into additional matters as if 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. When a party calls a hostile witness, an adverse party, a witness identified with an adverse party, or an expert witness, interrogation may be by leading questions.
