The U.S. Supreme Court on Tuesday granted a request by President Joe Biden's administration to reinstate – at least for now – a federal regulation aimed at reining in privately made firearms called "ghost guns" that are difficult for law enforcement to trace.

The justices put on hold a decision by U.S. District Judge Reed O'Connor in Fort Worth, Texas that had blocked the 2022 rule nationwide pending the administration's appeal.

O'Connor found that the administration exceeded its authority under a 1968 federal law called the Gun Control Act in implementing the rule relating to ghost guns, firearms that are privately assembled and lack the usual serial numbers required by the federal government.

The 2022 rule, issued by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) to target the rapid proliferation of the homemade weapons, bans "buy build shoot" kits that individuals can get online or at a store without a background check. The kits can be quickly assembled into a working firearm.

The rule clarified that ghost guns qualify as "firearms" under the Gun Control Act, expanding the definition of a firearm to include parts and kits that may be readily turned into a gun. It required serial numbers and that manufacturers and sellers be licensed. Sellers under the rule also must run background checks on purchasers prior to a sale.

A Justice Department spokesperson praised the court's decision, saying that the rule "is about public safety – helping law enforcement solve crimes and reducing the number of untraceable ghost guns flooding our communities."

One of the rule's challengers, the Firearms Policy Coalition gun rights group, said in a statement it was "deeply disappointed" with the decision but remained confident it would again win on appeal.

A Reuters/Ipsos poll completed on Tuesday found that 70 percent of Americans support requirements that ghost guns have serial numbers and be produced only by licensed manufacturers. The idea had bipartisan support among respondents, with 80 percent of Democrats and 61 percent of Republicans in favor.

There were about 20,000 suspected ghost guns reported in 2021 to the ATF as having been recovered by law enforcement in criminal investigations – a tenfold increase from 2016, according to White House statistics.

The United States, with the world's highest gun ownership rate, remains a nation deeply divided over how to address firearms violence including frequent mass shootings.

In three major rulings since 2008, the Supreme Court has widened gun rights, including a 2022 decision that declared for the first time that the U.S. Constitution protects an individual's right to carry a handgun in public for self-defense.
