Joe Biden’s ATF regulation on ghost guns, requiring serial numbers, background checks and more was just upheld by the Supreme Court in a vote of 7-2, with Thomas and Alito dissenting.

Here’s the news via the AP:

The Supreme Court on Wednesday upheld a Biden administration regulation on the nearly impossible-to-trace weapons called ghost guns, clearing the way for continued serial numbers, background checks and age verification requirements to buy them in kits online.

Seven justices joined the opinion, authored by Justice Neil Gorsuch, upholding the rule. Two justices, Clarence Thomas and Samuel Alito, dissented.

Ghost gun sales have grown exponentially since kits that let people build them easily at home came into the market, Gorsuch wrote. “Some home hobbyists enjoy assembling them. But criminals also find them attractive,” he said.

The number of ghost guns found at crime scenes around the country has also soared, according to federal data. They rose from fewer than 1,700 recovered by law enforcement in 2017 to more than 27,000 in 2023, according to Justice Department data.

Since the federal rule was finalized, though, ghost gun numbers have flattened out or declined in several major cities, including New York, Los Angeles, Philadelphia and Baltimore, according to court documents. Manufacturing of miscellaneous gun parts also dropped 36% overall, the Justice Department has said.

Now I assume, at least in the interim, that President Trump’s ATF can rescind the rule. But if that’s true, it would only be temporary given it would be at the whim of whichever administration is in office since the Supreme Court just upheld it.
