Rule 608. Evidence of Character for Truthfulness or Untruthfulness

    The credibility of a witness may be attacked or supported by evidence in the form of opinion or reputation, provided, however, that the evidence relates only to the witness' character for truthfulness or untruthfulness, and provided further that evidence of truthful character is admissible only after the character of the witness for truthfulness has been attacked by opinion or reputation evidence or otherwise.

    Evidence of the beliefs or opinions of a witness on matters of religion is not admissible for the purpose of showing that by reason of their nature the witness' credibility is impaired or enhanced.

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. 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.

Rule 612. Writing Used to Refresh Memory.

    Except as otherwise provided by law in criminal proceedings, if a witness while testifying uses a writing to refresh the witness' memory for the purpose of testifying, an adverse party is entitled to have the writing produced at the hearing for inspection and use in cross-examining the witness. The adverse party shall also be entitled to introduce in evidence those portions which relate to the testimony of the witness but only for the purpose of impeaching the witness. If it is claimed that the writing contains material not related to the subject of the testimony, the court shall examine the writing in camera and excise any unrelated portions. If the witness has used a writing to refresh the witness' memory before testifying, the court in its discretion and in the interest of justice may accord the adverse party the same right to the writing as that party would have if the writing had been used by the witness while testifying

This rule doe not apply to admissions of a party opponent as defined in Rule 803(b).
