Elliott-Larsen Civil Rights Act
The Elliott-Larsen Civil Rights Act (ELCRA), or Public Act 453 of 1976, which went into effect in 1977, originally prohibited discrimination in Michigan only on the basis of "religion, race, color, national origin, age, sex, height, weight, familial status, or marital status" in employment, housing, education, and access to public accommodations. A ruling by the Michigan Supreme Court on July 28, 2022 expanded the scope of the law to explicitly include protections for LGBT people.
