Civil procedure: civil actions; civil actions against certain opioid litigation settlement defendants; prohibit. Amends secs. 2 & 3 of 2022 PA 85 (MCL 691.1672 & 691.1673).

SB 616 prohibits Michigan local governments (such as counties, cities, and school districts) from filing new lawsuits against certain opioid settlement defendants for claims already covered by specific agreements. The bill blocks legal actions related to "released claims" under settlements with companies like CVS, Walgreens, Walmart, and others, with effective dates ranging from January 1, 2021 (for distributor settlements) to January 1, 2025 (for most other settlements). This means local governments cannot pursue the same claims that were settled under these agreements after the specified deadlines. The law applies to all local government entities (political subdivisions) but does not affect the state of Michigan itself.
