Michigan Repeals Pharma Immunity Provision

Michigan recently signed into law a repeal of the immunity provision under its Product Liability Act, presenting a new litigation risk in Michigan for pharmaceutical companies. The provision had granted near-complete immunity to pharma for the past 30 years, as the only of its kind nationwide.  Michigan’s new law—Senate Bill 410 (SB 410)—removes this immunity, leaving intact a rebuttable presumption of non-liability and caps on non-economic damages.  

SB 410 goes into effect on February 13, 2024, and is likely non-retroactive, meaning alleged injuries would have to occur after that date for the new law to apply.  Commentators predict increased Michigan litigation relating to opioid use, insulin price gouging, and Medicaid fraud.
