What was the decision of the supreme court in plessy v. ferguson[1896]?

This 1896 U.S. Supreme Court case upheld the constitutionality of segregation under the “separate but equal” doctrine. It stemmed from an 1892 incident in which African-American train passenger Homer Plessy refused to sit in a Jim Crow car, breaking a Louisiana law. Rejecting Plessy’s argument that his constitutional rights were violated, the Court ruled that a state law that “implies merely a legal distinction” between whites and blacks did not conflict with the 13th and14th Amendments. Restrictive legislation based on race continued following the Plessy decision, its reasoning not overturned until Brown v. Board of Education of Topeka in 1954.
