About Printz v. United States
Printz v. United States, 521 U.S. 898 (1997), is the Supreme Court decision that struck down the Brady Act’s interim requirement that local chief law enforcement officers perform background checks on prospective handgun buyers. Before the FBI’s National Instant Criminal Background Check System came online in 1998, the Brady Act directed sheriffs and police chiefs to make a reasonable effort to determine whether a buyer was legally eligible. Two sheriffs challenged that mandate: Jay Printz of Ravalli County, Montana, and Richard Mack of Graham County, Arizona.
Writing for a 5-4 majority, Justice Antonin Scalia held that the federal government may not command state officers to administer or enforce a federal regulatory program, a principle known as the anti-commandeering doctrine, grounded in the Constitution’s structure of dual sovereignty and the Tenth Amendment. Justice Clarence Thomas wrote a concurrence noting the Second Amendment questions the case raised. The ruling did not strike down the Brady Act’s waiting period or the federal background check system itself, but it remains a key precedent for states and localities that decline to enforce federal firearms rules, including modern Second Amendment sanctuary measures.
