The Department of Justice is amending the regulations of the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) regarding the making or transferring of a firearm under the National Firearms Act. This final rule standardizes the requirements by ensuring that responsible persons for a trust or legal entity are subject to the same identification and background check requirements as individuals. To lessen potential compliance burdens for the public and law enforcement, this final rule eliminates the requirement for a certification signed by the chief law enforcement officer (CLEO) and instead requires CLEO notification. The final rule also clarifies the definition “responsible person” for a trust or legal entity to address concerns about the definition’s scope while maintaining the important objective of ensuring background checks for relevant parties associated with a trust or legal entity.
