Federal and State Power

  • *McCulloch v Maryland*

    This case established two important principles in constitutional law. First, the Constitution grants to Congress implied powers for implementing the Constitution's express powers, in order to create a functional national government. Second, state action may not impede valid constitutional exercises of power by the Federal government.
  • *Gibbons v Ogden*

    the power to regulate interstate commerce, granted to Congress by the Commerce Clause of the United States Constitution, encompassed the power to regulate navigation.
