This Law Firm Publication by Jackson Lewis P.C. addresses Rouch World, LLC et al. v. Department of Civil Rights et al., in which the Michigan Supreme Court overruled prior court precedent and held that the prohibition of sex-based discrimination in Michigan's Elliott-Larsen Civil Rights Act extends to discrimination based on sexual orientation. The court adopted the US Supreme Court's reasoning in Bostock v. Clayton County, and concluded that discrimination on the basis of sexual orientation inherently involves discrimination on the basis of sex because a person's sexual orientation is determined by reference to their own sex.
