What was the final decision by the Supreme Court in the Plessy v Ferguson case?

In the Plessy v. Ferguson case of 1896, the Supreme Court upheld the constitutionality of racial segregation under the "separate but equal" doctrine. The Court ruled that state-sponsored segregation did not violate the Equal Protection Clause of the Fourteenth Amendment, effectively legitimizing discriminatory laws. This decision reinforced racial segregation and discrimination in the United States for decades until it was eventually overturned by Brown v. Board of Education in 1954.
