Problem
Federalism is a term that is used to describe authority that is held by two or more levels of government. Since the founding of the United States under the Constitution in 1787, sovereignty has been divided between the national and state governments. Still, this says little about what federalism has meant across time periods. In adjudicating legal controversies, the Supreme Court has contributed significantly to the construction of federalism's parameters in American history. How can I describe the Courts jurisprudence has reflected changing conceptions of national and state powers and how it has justified these new distributions of power? How does the court delineated and re-defined judicial, congressional, and state powers from 1787 until post New Deal times?
