Answer :
14th Amendment's equal protection clause can be used by the Supreme Court to strike down racial segregation in-state public schools.
Marshall presented the case to the Court on his own. Although he presented several legal arguments in his appeal, the most frequent one was that black and white separate school systems were fundamentally unfair and thus infringed upon the "equal protection provision" of the U.S. Constitution.
The Equal Protection Clause of the 14th Amendment prohibits states from passing or enforcing laws that limit the rights or privileges of US citizens, from taking someone's life, liberty, or property without providing them with a fair trial, and from denying anyone living within their borders the same legal protections as others.
