• The Supreme Court ordered two internet sellers of gun parts to comply with a Biden administration regulation targeting ghost guns, firearms that lack serial numbers and are difficult to trace.
  • The regulation expanded the definition of a firearm under federal law to include unfinished parts, imposing licensing requirements and background checks for all types of firearms, including those made from individual parts, kits, or 3D printers.
  • The decision marks the second time the Supreme Court has acted against a federal judge’s order, ensuring the regulation remains in effect as the administration appeals the ruling.
