Federal ghost gun regulations temporarily revived by Justice Alito

Supreme Court Justice Samuel Alito agreed on Friday to temporarily freeze a lower court order that bars the government from regulating so-called ghost guns - untraceable homemade weapons - as firearms under federal law.

Alito acted alone because he has jurisdiction over the lower court involved in the dispute. In the brief order Alito asked for a response from challengers to the regulation by August 2 and suggested the full Supreme Court will rule by August 4.

At issue is a request from the Biden administration to allow the regulations to remain in effect while legal challenges play out.

"Ghost guns" are kits that a user can buy online to assemble a fully functional firearm. They have no serial numbers, do not require background checks, and provide no transfer records for easy traceability. Critics say they are attractive to people who are legally prohibited from buying firearms.

In 2022, the Bureau of Alcohol, Tobacco, Firearms and Explosives updated its regulations to define the kits as firearms under the law so that the government could more carefully track them. The rule does not prohibit the sale or possession of any firearm nor does it block an individual from purchasing such a kit. Instead, it requires compliance with federal laws that impose conditions on the commercial sale of firearms. Those conditions include requirements that commercial manufacturers and sellers mark products with serial numbers and keep records to allow law enforcement to trace firearms used in crimes.

In late June, Judge Reed O'Connor of the United States District Court for the Northern District of Texas held that the agency had exceeded its authority in promulgating the rule and blocked it nationwide. A federal appeals court declined to put on hold two key challenged provisions of the regulation.

In the emergency filing with the Supreme Court, Solicitor General Elizabeth Prelogar warned the justices that over the last several years "police departments around the Nation have confronted an explosion of crimes involving ghost guns."
