The Supreme Court on Thursday revived a lawsuit from an Ohio woman who claimed she was the victim of reverse discrimination because her employer denied her a promotion because she is straight.

In a unanimous decision in the case of Ames v. Ohio Department of Youth Services, the high court tossed out a ruling by a federal appeals court that dismissed Marlean Ames’ claims because she failed to clear a higher bar applied to members of a majority group in order for her employment discrimination case to proceed. The justices concluded that a “background circumstances” requirement cannot be squared with Title VII of the Civil Rights Act and sent Ames’ case back to the lower courts for further proceedings.

The background circumstances rule required plaintiffs who are members of a majority group to put forth more evidence showing that their employer is “unusual” because it discriminates against the majority. Ames had argued that the requirement unfairly imposed a higher burden on her as a heterosexual woman.
