Text of the Commerce Clause

Article I, Section 8, Clause 3: "The Congress shall have Power ... To regulate Commerce with foreign Nations, and among the several States, and with the Indian Tribes."

Historical Context

The Commerce Clause was included in the Constitution to address the economic disarray under the Articles of Confederation, where states had various and conflicting regulations on trade. The framers sought to create a strong national economy by empowering Congress to regulate interstate and international commerce.

Key Supreme Court Cases

  • Gibbons v. Ogden (1824): The Supreme Court ruled that the power to regulate interstate commerce was an exclusive power of Congress, thus invalidating conflicting state regulations.
  • Wickard v. Filburn (1942): The Supreme Court expanded the scope of the Commerce Clause to include activities that have a substantial effect on interstate commerce.
  • United States v. Lopez (1995): The Supreme Court emphasized the limits of the Commerce Clause, ruling that Congress had overstepped its bounds by regulating non-economic activities.
