Karl Butler was charged in Kalamazoo County with five counts of first-degree criminal sexual conduct and one count of home invasion over a 2009 incident. He admitted the sexual contact and said it was consensual. His defense turned on evidence that the complainant had accused two other men of sexual assault in 2008, and that the accusation was false: the defense had statements from the two men and police reports on the earlier investigation.
The pretrial fight over that evidence consumed years. The trial court first denied the motion to admit it. On a renewed motion, the court changed course and ruled that the testimony could come in, but it never first held the closed evidentiary hearing Michigan law requires. The Court of Appeals reversed and held the evidence should be excluded. In March 2024, the Michigan Supreme Court, in a unanimous decision, vacated that decision too. Both lower courts had skipped the required step: once the defense produced some apparently credible and potentially admissible evidence that the earlier allegation was false, the trial court had to hold an in camera evidentiary hearing before deciding anything about admissibility.
People v. Butler is one recent answer to a question that runs through nearly every Michigan criminal sexual conduct prosecution: when does the exclusion of defense evidence cross the line from ordinary evidence law into a violation of the constitutional right to present a defense? The Michigan Supreme Court has confronted that question twice in two years, in Butler and in the 2025 rape-shield decision People v. Masi, and the Court of Appeals added a published decision on records discovery, People v. Leonard, in June 2026.
