(a) Questions of Admissibility Generally. Preliminary questions concerning the qualification of a person to be a witness, the existence of a privilege, or the admissibility of evidence shall be determined by the court, subject to the provisions of subdivision (b). In making its determination the court is not bound by the rules of evidence except those with respect to privileges.
(b) Relevancy Conditioned on Fact. When the relevancy of evidence depends upon the fulfillment of a condition of fact, the court shall admit it upon, or subject to, the introduction of evidence sufficient to support a finding of the fulfillment of the condition.
(c) Hearing of Jury. In a criminal case, a hearing on the admissibility of a confession shall be conducted out of the hearing of the jury. All other civil or criminal hearings on preliminary matters shall be conducted out of the hearing of the jury when the interests of justice so require or in a criminal case when an accused is a witness and so requests.
(d) Testimony by Accused Out of the Hearing of the Jury. The accused in a criminal case does not, by testifying upon a preliminary matter out of the hearing of the jury, become subject to cross-examination as to other issues in the case.
(e) Weight and Credibility. This rule does not limit the right of a party to introduce before the jury evidence relevant to weight or credibility.
