Rule 611. Mode and order of interrogation and presentation; re-examination and recall; confrontation.
(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) Cross-examination should be limited to the subject matter of the direct examination and matters affecting the credibility of the witness. The court may, in the exercise of discretion, permit inquiry into additional matters as if on direct examination.
(2) Evidence developed on cross-examination may be considered by the trier of fact as proof of any fact in issue in the case.
(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, or a witness identified with an adverse party, interrogation may be by leading questions.
(d) Re-examination and recall. A witness may be re-examined as to the same matters to which the witness testified only in the discretion of the court, but without exception the witness may be re-examined as to any new matter brought out during cross-examination. After the examination of the witness has been concluded by all the parties to the action, that witness may be recalled only in the discretion of the court. This rule shall not limit the right of any party to recall a witness in rebuttal.
(e) Confrontation. Except as otherwise provided by constitution, statute, these rules, or other rules applicable to the courts of this state, at the trial of an action, a witness can be heard only in the presence and subject to the examination of all the parties to the action, if they choose to attend and examine.
