The US Supreme Court has upheld a Biden administration regulation on so-called ghost guns, clearing the way for the continued use of serial numbers, background checks and age verification requirements to buy them in kits online.

The 7-2 opinion found that existing gun laws allow regulation of the kits which are increasingly linked to crime.
