SD HB1132

Prohibits South Dakota state and local officials from using personnel, property, or money to assist federal authorities in enforcing federal firearm measures enacted on or after July 1, 2026, that are more restrictive than state law

Targeted federal measures include firearm registries, owner registries, licensing/permitting requirements, private sale background checks, confiscation programs, and mandatory surrender programs

Violations constitute a Class 1 misdemeanor, with each act of "material aid" (sharing information, using equipment/facilities, spending funds, or joint task force participation) as a separate offense

Any person may bring civil action against the state or political subdivisions for violations, with courts authorized to impose penalties up to $50,000 per violation plus attorney's fees

Whistleblower protections provided for employees who report or refuse to participate in suspected violations, including reinstatement and back pay remedies
