Madison5 U.S. 37 (1803).  Chief Justice John Marshall penned the opinion, holding that the federal courts had the power to review acts passed by Congress to determine their constitutionality.  “A law repugnant to the Constitution is void.”  The opinion helped to solidify the concept of checks and balances and the equality between the executive, legislative and judicial branches under the Constitution.
