Richard Mack v. United States

Opinion summary

Etalia.ai summary of the majority opinion

The case addressed the constitutionality of certain provisions in the Brady Handgun Violence Prevention Act, which required local chief law enforcement officers (CLEOs) to conduct background checks on prospective handgun purchasers. Richard Mack, a sheriff from Arizona, challenged these requirements as unconstitutional under the Tenth Amendment. The Supreme Court held that Congress could not compel state officials to enforce federal regulatory programs. This decision was based on principles of federalism and dual sovereignty inherent in the Constitution. The ruling emphasized that while Congress may regulate individuals directly through its enumerated powers, it cannot commandeer state governments into enforcing or administering federal mandates.
