Parents’ discrimination against their children is lawful. But the family, as an institution in which social goods are allocated, is as significant as the sites in which anti-discrimination law operates. At least prima facie, therefore, parents should be governed by legal prohibitions on discrimination. While state incursion into family life poses a threat to children’s autonomy, so does parental discrimination against children. Anti-discrimination law therefore needs new institutions to promote the values of non-discrimination in a part of society that currently sits outside anti-discrimination law’s reach. We identify existing regimes that may provide a starting point for this work.
