Federal civil rights law protects gay, lesbian and transgender workers, the Supreme Court has ruled.
The landmark ruling will extend protections to millions of workers nationwide and is a defeat for the Trump administration, which argued that Title VII of the Civil Rights Act that bars discrimination based on sex did not extend to claims of gender identity and sexual orientation.
The 6-3 opinion was written by Justice Neil Gorsuch and joined by Chief Justice John Roberts and the court's four liberal justices.
"Ours is a society of written laws. Judges are not free to overlook plain statutory commands on the strength of nothing more than suppositions about intentions or guesswork about expectations," Gorsuch, one of the court's conservatives, wrote in the majority opinion.
"In Title VII, Congress adopted broad language making it illegal for an employer to rely on an employee's sex when deciding to fire that employee. We do not hesitate to recognize today a necessary consequence of that legislative choice: An employer who fires an individual merely for being gay or transgender defies the law," he added.
