On September 11, 2012, HB 5864 was introduced by Representatives Lyons and Haveman. The bill amends the 3rd party tort provisions of Section 3135 of the Michigan No-Fault Act. Specifically, this bill changes the current legislative definition of the tort threshold requirement of "serious impairment of body function," which is the injury threshold that must be met before an auto accident survivor can sue the at-fault driver for non-economic loss damages (also known as pain and suffering damages).The bill could eliminate almost all third-party tort claims against at-fault drivers.
