In a unanimous decision, the U.S. Supreme Court Thursday upheld the claims of a woman who faced workplace discrimination because of her “majority group” identity—in this case, being a heterosexual.

The decision upholds the rights of majority group individuals to be free from “reverse discrimination,” a right considered protected under Title VII of the Civil Rights Act of 1964.

Justice Ketanji Brown Jackson delivered the opinion. Justice Clarence Thomas delivered a concurring opinion, in which Justice Neil Gorsuch joined.

The court struck down the “background circumstances” rule imposed by the Sixth Circuit Court of Appeals, a rule that restricts protections for members of majority groups.
