The Emergency Powers of Governor Act is the law Gov. Gretchen Whitmer is using to unilaterally control the state's response to the COVID-19 pandemic. This report explains how this law was used by previous governors. Until 2020, it was used 11 times in response to five emergency situations: labor unrest in Hillsdale in 1964, urban riots in 1967, more riots in 1968, high mercury levels in waters near St. Clair in 1970 and for a riot in Ypsilanti in 1970.
