- U.S. District Judge Brian Wimes enjoined the law in 2023, and the 8th U.S. Circuit Court of Appeals affirmed in 2024.
- Passed in 2021, the law declares certain federal firearms restrictions unconstitutional and allows fines up to $50,000 against state or local officials who help enforce them.
- The statute does not specify which federal rules it targets and fails to define key terms such as “law-abiding,” which the Biden administration said caused agencies to withdraw cooperation with federal enforcement.
