The Court of Appeals for the 2nd Circuit ruled Monday, “We now hold that sexual orientation discrimination constitutes a form of discrimination ‘because of . . . Sex,’ in violation of Title VII.” In doing so, the court overruled a lower court — and a precedent from two previous court cases — and remanded the case to be litigated in light of their reading of Title VII.

The decision holds national implications due to its high tier in the judicial system, and because it’s seen as a litmus test of the Trump administration’s ability — or inability — to curb LGBT rights through court activism. The Justice Department had injected itself into the case even though it wasn’t a party to the lawsuit and doesn’t normally involve itself in private employment disputes.

The case was heard in New York City by all 13 judges in the 2nd Circuit, known as an en banc hearing, which leaves the Supreme Court as the only avenue for a potential appeal.
