Evidence of prior false allegations by complaining witnesses in sexual offense trials faces significant admissibility hurdles under MRE 412, which generally prohibits sexual behavior evidence. However, constitutionally required exceptions may permit such evidence when necessary for fair trials. The defense must demonstrate that prior allegations were demonstrably false, not merely unsubstantiated or resulting in acquittals. Clear evidence of fabrication, recantations, or admissions of lying may qualify.
Procedural requirements include sealed motions, in camera hearings, and specific relevance showing. Judges balance probative value against privacy concerns and potential prejudice. The evidence must directly relate to credibility rather than general character attacks. Pattern evidence showing multiple false allegations strengthens admissibility arguments. Temporal proximity and similarity to current allegations affect relevance determinations.
Even when admissible, judges strictly limit scope to prevent fishing expeditions through complainants’ histories. Specific instances of proven fabrication may be explored, but general credibility attacks remain prohibited. The defense cannot introduce evidence merely showing prior allegations didn’t result in convictions. Constitutional confrontation rights may override MRE 412 when false allegation evidence is crucial to defense. The area remains contentious, with appellate courts reversing both overly restrictive and overly permissive rulings. Careful documentation of false allegation proof and direct relevance to current charges enhances admissibility prospects.
