The immediate dispute in the case of Plessy v. Ferguson was between the state of Louisiana and Homer Plessy over whether Plessy had to pay a $25 fine to the state. In order to resolve that dispute, the Supreme Court had to decide which of the following things? Does the constitutional power to regulate interstate commerce extend to railroads on trips within a single state? Does the Fourteenth Amendment permit states to require people of different races to be separated from one another in some circumstances? Does the Constitution require the national government to oversee state laws on transportation? Does the Constitution's rule against cruel and unusual punishment require state governments to limit the size of fines levied for breaking laws
