U.S. District Judge Reed O’Connor issued a ruling on Monday invalidating a 2022 Biden administration regulation that sought to tighten oversight of so-called "ghost guns." These firearms are typically sold as kits or parts that individuals assemble at home, often lacking serial numbers that allow law enforcement to track them. The administration's rule had aimed to classify these kits as firearms under federal law, thereby requiring background checks and serial numbers for their sale.

In his decision, Judge O’Connor argued that the federal government exceeded its authority by attempting to regulate the self-manufacture of firearms. He pointed to the nation’s "historical tradition" of personal gunsmithing, suggesting that the government's attempt to treat these home-assembled items the same as commercially manufactured weapons was legally flawed. The ruling effectively halts the enforcement of the 2022 measure, which was a cornerstone of the administration's efforts to curb the proliferation of untraceable weapons.

The decision represents a significant legal setback for the Biden administration's gun control agenda. While the administration has argued that such regulations are necessary to prevent criminals from obtaining untraceable weapons, opponents of the rule—and now the court—have maintained that the regulation infringes upon the rights of individuals to build their own firearms. The ruling is expected to be appealed by the Department of Justice, as the administration continues to defend its regulatory approach to firearm safety. As of now, the legal status of these kits remains in flux, pending further action from higher courts.
