Federalism, State Sovereignty and the Constitution: Basis and Limits of Congressional Power [Updated June 17, 2005] [open pdf - 108KB]
"The ratification of the Constitution, to a significant extent, defined the lines of authority between the state and federal governments. Over recent years, the Supreme Court has decided a number of cases which address this historical relationship. This report discusses state and federal legislative power generally and focuses on a number of these 'federalism' cases. Issues addressed include congressional power under the Commerce Clause and the Fourteenth Amendment; constitutional limits on congressional powers, such as the Tenth Amendment; and state sovereign immunity under the Eleventh Amendment. The report does not, however, address the much larger policy issue of when it is appropriate--as opposed to constitutionally permissible-- for federal powers to be exercised."
