Why did the Supreme Court decide to overturn Plessy v Ferguson as explained in Brown v Board of Education Brainly?

Plessy v. Ferguson, legal case in which the U.S. Supreme Court on May 18, 1896, by a seven-to-one majority (one justice did not participate), advanced the controversial “separate but equal” doctrine for assessing the constitutionality of racial segregation laws. Plessy v. Ferguson was the first major inquiry into the meaning of the Fourteenth Amendment’s (1868) equal-protection clause, which prohibits the states from denying “equal protection of the laws” to any person within their jurisdictions. Although the majority opinion did not contain the phrase “separate but equal,” it gave constitutional sanction to laws designed to achieve racial segregation by means of separate and supposedly equal public facilities and services for African Americans and whites. It served as a controlling judicial precedent until it was overturned by the Supreme Court in Brown v. Board of Education of Topeka (1954).

The case originated in 1892 as a challenge to Louisiana’s Separate Car Act (1890). The law required that all railroads operating in the state provide “equal but separate accommodations” for white and African American passengers and prohibited passengers from entering accommodations other than those to which they had been assigned on the basis of their race. In 1891 a group of Creole professionals in New Orleans formed the Citizens’ Committee to Test the Constitutionality of the Separate Car Law. They hired Albion Tourgée, a Reconstruction-era judge and social reformer, as their legal counsel. As plaintiff in the test case the committee chose a person of mixed race in order to support its contention that the law could not be consistently applied, because it failed to define the white and “coloured” races. Homer Plessy, who was seven-eighths white and one-eighth African American, purchased a rail ticket for travel within Louisiana and took a seat in a car reserved for white passengers. (The state Supreme Court had ruled earlier that the law could not be applied to interstate travel.) After refusing to move to a car for African Americans, he was arrested and charged with violating the Separate Car Act. At Plessy’s trial in U.S. District Court, Judge John H. Ferguson dismissed his contention that the act was unconstitutional. After the state Supreme Court affirmed the district court’s ruling, the U.S. Supreme Court granted certiorari, and oral arguments were heard on April 13, 1896. The court rendered its decision one month later, on May 18.
