when did the supreme court rule that bus segregation was unconstitutional
Montgomery bus boycott Black activists had begun to build a case to challenge state bus segregation laws around the arrest of a 15-year-old girl, Claudette Colvin, a student at Booker T. Washington High School in Montgomery. On March 2, 1955, Colvin was handcuffed, arrested and forcibly removed from a public bus when she refused to give up her seat to a white man. At the time, Colvin was an active member in the NAACP Youth Council; Rosa Parks was an advisor.[14] Colvin's legal case formed the core of Browder v. Gayle, which ended the Montgomery bus boycott when the Supreme Court ruled on it in December 1956.
