The Worst Judge Ever Has Entered the Gun Debate

The Donald Trump–appointed federal judge responsible for suspending federal approval for mifepristone is back, and he’s once again attempting to undermine the authority of a federal agency.

Last week, Texas Judge Matthew Kacsmaryk issued a preliminary injunction preventing the federal government from enforcing a controversial new rule from the Bureau of Alcohol, Tobacco, Firearms and Explosives, which expanded the definition of being “engaged in business” as a gun seller.

The new rule would require more sellers at gun shows to perform background checks on their buyers, shrinking—but not entirely solving—the long-standing “gun show loophole” that allows gun show vendors to skirt the accountability measures taken by other firearms dealers.

The rule, which went into effect in May, sparked a lawsuit from GOP-led states Texas, Louisiana, Mississippi, and Utah, as well as one gun owner in Amarillo, Texas, where—wouldn’t you know it—Kacsmaryk happens to be the only federal judge. Any group that files a lawsuit in Amarillo can essentially guarantee that the far-right judge will be the one to hear it, making that district a hot spot for lawsuits from conservative groups.

The gun owner in the suit is backed by the Virginia Citizens Defense League, the Tennessee Firearms Association, and the Gun Owners of America.

In his 22-page ruling, Kacsmaryk wrote that the plaintiffs would likely succeed in their argument that the ATF had overstepped the Administrative Procedure Act by changing the rule without congressional approval and that expanding the definition of gun sellers put the burden on “gun owners [to] prove innocence, rather than the government [to] prove guilt.” He enjoined the ruling, meaning that the new ATF rule cannot be enforced in any of the plaintiff states, until the lawsuit is resolved.

Kacsmaryk’s injunction follows a similar tactic in his infamous ruling last year threatening nationwide mifepristone access: to undermine the authority of a federal agency. He issued a ruling overturning the Food and Drug Administration’s approval of the abortion pill, which had been on the market for nearly 20 years. Kacsmaryk, who has long-standing ties to the anti-abortion movement, deployed a Victorian-era rule in his argument to ban the drug, which he also cited in a separate ruling to ban drag performances.

Ultimately, the Supreme Court declined to override the FDA’s authority. It is unclear if it will follow the same line of thinking should the gun seller case reach the high court.
