 Plessy's action ultimately led to the "Plessy v. Ferguson" (1896) decision by the United States Supreme Court, which affirmed the legality of "separate-but-equal" facilities.In practice, segregated facilities were seldom equal; those for blacks being consistently underfunded by white-dominated legislatures and local governments.Antoine's committee also challenged a state law forbidding racial intermarriage, but did not succeed in having it declared unconstitutional.
