Normally we don’t think of administrative agencies as policing constitutional equality norms. There’s a good reason for this—courts are often thought of as the “ultimate expositor” of constitutional meaning, while agencies are thought of as undertaking not constitutional interpretation, but statutory implementation. But recently scholars have explored the ways in which constitutionalism enters agency decisionmaking—commonly referred to as “administrative constitutionalism.” Administrative constitutionalism theories loosen the assumption that courts have a monopoly on constitutional understanding, and instead recognize agencies as constitutional actors in their own right. This Note explores how agencies have engaged in administrative constitutionalism to police LGBT equality rights—often in ways that differ markedly from judicial applications of equal protection. It then offers a defense of these practices, arguing that agencies have acted in the face of widespread underenforcement of equality norms by the judiciary owing largely to institutional considerations that—justified or not—have no bearing on the meaning of equal protection.
