Mich. R. Evid. 407
As amended through November 20, 2024
When measures are taken that would have made an event less likely to occur, evidence of subsequent measures is not admissible to prove negligence or culpable conduct in connection with the event. But the court may admit this evidence for another purpose, such as impeachment or - if disputed - proving ownership, control, or the feasibility of precautionary measures.
