A Missouri law banning local police from enforcing federal gun laws is unconstitutional and void, a federal judge ruled Tuesday.
U.S. District Judge Brian Wimes ruled the 2021 law is preempted by the federal government under the U.S. Constitution’s supremacy clause.
“At best, this statute causes confusion among state law enforcement officials who are deputized for federal task force operations, and at worst, is unconstitutional on its face," Wimes wrote.
The Missouri law had subjected law enforcement agencies with officers who knowingly enforced federal gun laws without equivalent state laws to a fine of $50,000 per violating officer.
Federal laws without similar Missouri laws include statutes covering weapons registration and tracking, and possession of firearms by some domestic violence offenders.
Conflict over Missouri’s law wrecked a crime-fighting partnership with U.S. attorneys that Missouri’s former Republican attorney general, now-Sen. Eric Schmitt, touted for years. Under Schmitt’s Safer Streets Initiative, attorneys from his office were deputized as assistant U.S. attorneys to help prosecute violent crimes.
The Justice Department, which last year sued to overturn the Missouri law, said the Missouri state crime lab, operated by the Highway Patrol, refused to process evidence that would help federal firearms prosecutions after the law took effect.
The Missouri Information and Analysis Center, also under the Highway Patrol, stopped cooperating with federal agencies investigating federal firearms offenses. And the Highway Patrol, along with many other agencies, suspended joint efforts to enforce federal firearms laws.
Wimes said police can now work with federal partners without worrying about breaking the voided law.
“State and local law enforcement officials in Missouri may lawfully participate in joint federal task forces, assist in the investigation and enforcement of federal firearm crimes, and fully share information with the Federal Government without fear of H.B. 85’s penalties,” the judge wrote.
Republican lawmakers who helped pass the bill said they were motivated by the potential for new gun restrictions under Democratic President Joe Biden, who signed the most sweeping gun violence bill in decades last year.
The federal legislation toughened background checks for the youngest gun buyers, keeps firearms from more domestic violence offenders and helps states put in place red flag laws that make it easier for authorities to take weapons from people adjudged to be dangerous.
