In one of its most important decisions in years, the Supreme Court has interpreted federal anti-discrimination law to prohibit discrimination on the basis of sexual orientation or transgender status. In a surprise to most observers, the decision was 6 -3, and written by Justice Neil Gorsuch, one of President Donald Trump's appointees.
The decision marks Gorsuch's most significant move thus far to take on the mantle of the late Justice Antonin Scalia as the intellectual leader of the conservative wing of the court. That may sound strange and counterintuitive: After all, Scalia harshly opposed landmark decisions expanding gay rights, and it's difficult to imagine him having joined the Gorsuch opinion.
Indeed, Justice Samuel Alito explicitly made Scalia the linchpin of his dissent, insisting (not implausibly) that Scalia could not possibly have been on board with a decision like this one. "The court's opinion is like a pirate ship," Alito memorably wrote. "It sails under [Scalia's] flag, but what it actually represents is a theory of statutory interpretation that Scalia excoriated."
Gorsuch's ploy might well work. Conservatives may be briefly frustrated by the outcome of this case. But it is liberals — mostly liberal law professors — who make or break judicial reputations. And liberal legal scholars, who have not liked Gorsuch much thus far, are now going to have to hold him up as a model of judicial honesty. He has applied his method to produce a result against his presumed political preferences. That makes him a hero of legal principle, at least for the moment.
Armed with that reputation, Gorsuch can make the case for himself as a leading judicial intellectual. It worked (to a degree) for Scalia, who was treated by liberals as a serious jurisprudential figure despite deep disagreement with his premises and his conclusions.
The ground on which Gorsuch is fighting is the theory of statutory interpretation known as "textualism." The basic idea is that, when interpreting federal law, judges should not ask what the authors of the law meant to say, or try to divine legislative intent from the Congressional Record or the political context. Rather, textualism says that the overwhelming focus of statutory interpretation should be the words of the law itself: the text.
Pushing this theory was one of Scalia's main contributions to contemporary legal thought. In his mind, textualism discouraged judges from using interpretation to make the law say something different from what the law actually said.
As applied to Title VII, the classic 1964 anti-discrimination law, the textualist idea is very simple. The law prohibits discrimination "on the basis of sex." To discriminate against somebody because of sexual orientation necessarily entails discriminating on the basis of sex. After all, if you're discriminating against a man because he is attracted to men, you would not be discriminating against him if he were a woman who is attracted to men.
