Richard Mack

Richard Ivan Mack is the former sheriff of Graham County, Arizona and is best known for his role in a lawsuit brought against the federal government of the United States which alleged that portions of the Brady Handgun Violence Prevention Act violated the United States Constitution. He is a former lobbyist for Gun Owners of America (GOA) and a two-time candidate for United States Congress. Mack is also the founder of Constitutional Sheriffs and Peace Officers Association (CSPOA), and established the "County Sheriff Project" movement, both of whom claim the power to refuse to enforce federal laws.

Mack v. United States

Mack served as Graham County Sheriff from 1988 to 1996. In 1994 he was recruited by the National Rifle Association as a plaintiff in one of nine lawsuits against the Clinton administration over the Brady Handgun Violence Prevention Act.

Mack v. United States (later restyled to Printz v. United States), a lawsuit against the federal government which alleged that portions of the Act violated the United States Constitution, because they comprised a congressional action that compelled state officers to execute Federal law. These portions were interim provisions until a national instant background check system for gun purchasers could be implemented. In a 5–4 decision, the Supreme Court ruled that the provisions of the Brady Act in question were, in fact, unconstitutional.
