Critics of the Supreme Court’s equal protection jurisprudence despair that the Court conceives of discrimination as the mere classification of individuals on forbidden grounds, such as race and sex, rather than systemic patterns of subordination. On the Court’s anticlassification theory, affirmative action, which relies on overt racial or gender classifications, is generally forbidden. Such context-insensitive anticlassification rules could, in principle, extend to individuals who are members of groups often regarded with hostility and suspicion, such as transgender people. Indeed, this is how most trial courts have approached recent laws that classify individuals based on sex to exclude transgender people. However, appellate courts have refused to take anticlassification rules seriously. This Article argues that all sex classifications, like all race-based ones, ought to trigger heightened constitutional scrutiny. It draws support from the principles undergirding anticlassification rules announced by the Roberts Court, most recently in its university affirmative action decisions.
