Hawaii Revised Statutes Division 4. Courts and Judicial Proceedings § 626-1, Rule 609

(a) General rule. For the purpose of attacking the credibility of a witness, evidence that the witness has been convicted of a crime is inadmissible except when the crime is one involving dishonesty. However, in a criminal case where the defendant takes the stand, the defendant shall not be questioned or evidence introduced as to whether the defendant has been convicted of a crime, for the sole purpose of attacking credibility, unless the defendant has oneself introduced testimony for the purpose of establishing the defendant's credibility as a witness, in which case the defendant shall be treated as any other witness as provided in this rule.

(b) Effect of pardon. Evidence of a conviction is not admissible under this rule if the conviction has been the subject of a pardon.

(c) Juvenile convictions. Evidence of juvenile convictions is admissible to the same extent as are criminal convictions under subsection (a) of this rule.

(d) Pendency of appeal. The pendency of an appeal therefrom does not render evidence of a conviction inadmissible. Evidence of the pendency of an appeal is admissible.
