Most influential court cases

For me the most influential case that we talk about as a class was Plessy vs. Ferguson because this case posed as a way for justice that black should be able to sit with the white, since under the constitution we are all equal. the historical question was can the states constitutionally enact legislation requiring persons of different races to use"separate but equal" segregated facilities? Yes the states can do that, because at that time the verdict and trial was corrupt. the decision was Ferguson 7 and Plessy 1 and because of that, later in Brown vs. Board, the state ruling was declared that not "all people are equal". There was some corruption and unfairness and it just showed me that back then and at times now, court rulings aren't fair but because of people who stand up, it's that there's change.
