Michigan § 750.520j - Evidence of victim's sexual conduct.

Evidence of specific instances of the victim's sexual conduct, opinion evidence of the victim's sexual conduct, and reputation evidence of the victim's sexual conduct shall not be admitted under sections 520b to 520g unless and only to the extent that the judge finds that the following proposed evidence is material to a fact at issue in the case and that its inflammatory or prejudicial nature does not outweigh its probative value:

Evidence of the victim's past sexual conduct with the actor.

Evidence of specific instances of sexual activity showing the source or origin of semen, pregnancy, or disease.

If the defendant proposes to offer evidence described in subsection (1)(a) or (b), the defendant within 10 days after the arraignment on the information shall file a written motion and offer of proof. The court may order an in camera hearing to determine whether the proposed evidence is admissible under subsection (1). If new information is discovered during the course of the trial that may make the evidence described in subsection (1)(a) or (b) admissible, the judge may order an in camera hearing to determine whether the proposed evidence is admissible under subsection (1).
