Gaines v. Canada, Registrar of the University of Missouri,  305 U.S. 337 (1938), the Supreme Court held that states that provided a law school to white students had to provide similar in-state education to blacks as well. States could satisfy this requirement by allowing blacks and whites to attend the same school or by creating a second school for blacks, but when the state provides legal training, it must provide it to every qualified person to satisfy equal protection.
In Gaines v. Canada (305 U.S. 337, 1938), the Supreme Court ruled that states offering law schools to white students were obligated to provide equivalent in-state education to blacks as well. States could fulfill this requirement by allowing both groups to attend the same school or by creating a separate black school, but when providing legal training, they must ensure equal access for all qualified individuals to uphold the principle of equal protection.
