Michigan Supreme Court

People v. Morgan

June 24, 2026

Summary

The Court held that the decedent's possible intoxication was relevant and admissible under the evidence rules because, considered with his alleged speeding and rapid acceleration, it could bear on gross negligence and proximate causation. The district court abused its discretion by evaluating the BAC evidence in isolation and by excluding it under both relevance and unfair-prejudice analyses. The Court reversed the Court of Appeals, vacated the district court's exclusion order, and remanded for further proceedings.
