Scrutinizing Sex
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. Anticlassification rules are insensitive to context: a classification is a classification, no matter how well-intentioned it might be, no matter what effects it might have, and no matter if it treats members of various groups in ways that are substantively equal. Whether a classification might be justified due to its purposes, effects, or substance is a separate inquiry demanding careful judicial scrutiny.
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—concluding that those laws trigger heightened scrutiny and asking whether they serve important governmental interests. However, in a series of recent sex discrimination cases involving transgender plaintiffs, appellate courts have refused to take anticlassification rules seriously. For these judges, a classification is not a classification if it appears, by their own dim normative lights, to treat the sexes equally. These courts give a free pass to sex classifications that target transgender people, declining to ask what important interests these laws might serve.
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. Rather than being empty formalism, as critics contend, anticlassification theory is based in principles related to individual autonomy. These principles provide no basis for defining what counts as a classification differently in the context of sex as opposed to race, nor do they support exceptions to equal protection for transgender people.
