Justice Antonin Scalia’s most significant legacy on the Supreme Court has not been in any area of constitutional law but with respect to statutory interpretation. His campaign against legislative purposivism—the theory that statutes should be construed to reflect the legislature’s purpose, or intent, to oversimplify things—and his commitment to formal, textualist modes of interpretation have had a profound effect on how litigants brief and argue cases to the court. (For those of you too young to recall how things used to be done, I’d offer as Exhibit A the fantastic 1979 brief my colleague Michael Gottesman filed in Steelworkers v. Weber, which included fully 50 pages of detailed, subtle exposition on the complex history and context of the 1964 Civil Rights Act—a narrative that the court largely embraced in its surprising decision in the case. No serious SCOTUS advocate in this generation—including Michael—would think of doing anything remotely similar today.)
