The US Supreme Court upheld the federal regulation of built-at-home “ghost gun” kits, backing a rule put in place during the Biden administration to stem what officials said was a torrent of untraceable weapons.

The 7-2 decision keeps in force a 2022 rule that subjects commercially sold gun kits to the same requirements as fully assembled firearms, requiring serial numbers and background checks. The Trump administration, which took no position in the court case, will now inherit the regulation.
