The U.S. Supreme Court will hear an appeal from the Biden administration next term over the validity of a new regulation aimed at banning so-called “ghost guns,” seeking to prevent a “flood of untraceable” weapons being made from firearm kits purchased over the internet.

The high court granted certiorari, or review, Monday in Garland v. VanDerStok, in which the Biden-run U.S. Department of Justice is appealing a lower court decision that found aspects of the ghost gun rule to be unlawful. The decision is not entirely a surprise, given the justices’ past intervention in the case to allow the regulation to remain in effect as the litigation moves forward.
