Mich. R. Evid. 104 (2026)

(a) In General. The court must decide any preliminary question about whether a witness is qualified, a privilege exists, or evidence is admissible. In so deciding, the court is not bound by evidence rules, except those on privilege. (b) Relevance That Depends on a Fact. When the relevance of evidence depends on whether a fact exists, proof must be introduced sufficient to support a finding that the fact does exist. The court may admit the proposed evidence on the condition that the proof be introduced later. (c) Conducting a Hearing so That the Jury Cannot Hear it. The court must conduct any hearing on a preliminary question so that the jury cannot hear it if: (1) the hearing involves the admissibility of a confession; (2) a defendant in a criminal case is a witness and so requests; or (3) justice so requires. (d) Cross-Examining a Defendant in a Criminal Case. By testifying on a preliminary question, a defendant in a criminal case does not become subject to cross-examination on other issues in the case. (e) Evidence Relevant to Weight and Credibility. This rule does not limit a party’s right to introduce before the jury evidence that is relevant to the weight or credibility of other evidence.
