The Supreme Court ruled that a landmark civil rights law protects LGBT people from discrimination in employment, a resounding victory for LGBT rights from a conservative court. The court decided by a 6-3 vote that a key provision of the Civil Rights Act of 1964 known as Title VII that bars job discrimination because of sex, among other reasons, encompasses bias against LGBT workers.

The cases were the court’s first on LGBT rights since Justice Anthony Kennedy’s retirement and replacement by Kavanaugh. Kennedy was a voice for gay rights and the author of the landmark ruling in 2015 that made same-sex marriage legal throughout the United States. Kavanaugh generally is regarded as more conservative.

The Trump administration had changed course from the Obama administration, which supported LGBT workers in their discrimination claims under Title VII. During the Obama years, the federal Equal Employment Opportunity Commission had changed its longstanding interpretation of civil rights law to include discrimination against LGBT people. The law prohibits discrimination because of sex, but had no specific protection for sexual orientation or gender identity.

In recent years, some lower courts have held that discrimination against LGBT people is a subset of sex discrimination, and thus prohibited by the federal law. Efforts by Congress to change the law had failed.

The Supreme Court cases involved two gay men and a transgender woman who sued for employment discrimination after they lost their jobs.
