And framing the policy debate are legal issues stemming from the existing federal framework of firearms laws and the constitutional constraints that may cabin Congress's ability to legislate in this area. Proposals to modify the current federal framework for regulating firearms may be informed by numerous constitutional considerations, including the scope of the Second Amendment right to keep and bear arms and the need to ground legislation in one of Congress's enumerated powers. Historical Overview of Major Federal Firearms Laws

Federal laws regulating firearms date back roughly a century, and over time lawmakers have established more stringent requirements for the transfer, possession, and transportation of firearms. Federal Statutory Framework

Firearms regulation in the United States is an area of shared authority among federal, state, and local governments. Individual states have enacted a variety of laws relating to the possession, registration, and carrying of firearms, among other things. Thus, the current collection of federal firearms laws may be thought of as a regulatory floor that sets out, at the federal level, the minimum requirements for lawful manufacture, sale, and possession of firearms. The two principal federal firearms laws currently in force are the NFA and the GCA, as amended. National Firearms Act of 1934

The NFA was the first major piece of federal legislation regulating the sale and possession of firearms. Through a taxation and registration scheme, the law sought to curb the rise of violence connected to organized crime by targeting the types of weapons that (at the time of passage) were commonly used by gang members. Gun Control Act of 1968

Congress passed the GCA in the wake of the assassinations of Dr. Martin Luther King Jr. and Senator Robert Kennedy to "keep firearms out of the hands of those not legally entitled to possess them because of age, criminal background, or incompetency and to assist law enforcement authorities in the states and their subdivisions in combating the increasing prevalence of crime in the United States." The GCA today is not a single statute but rather a complex statutory regime that has been supplemented regularly in the decades since its inception. Broadly speaking, the GCA, as amended, regulates the manufacture, transfer, and possession of firearms, extending to categories of weapons that fall outside the scope of the NFA. In general terms, the GCA sets forth who can—and cannot—sell, purchase, and possess firearms; how those sales and purchases may lawfully take place; what firearms may lawfully be possessed; and where firearm possession may be restricted. Possession " by a prohibited person . To implement the Brady Act, the FBI created the National Instant Criminal Background Check System (NICS), which launched in 1998. Constitutional Considerations

Numerous constitutional considerations may inform congressional proposals to modify the current framework for regulating firearms sales and possession. Although Congress has broad constitutional authority to regulate firearms, any firearm measure must be rooted in one of Congress's enumerated powers. In enacting firearms laws, Congress has typically invoked its tax, commerce, and spending powers. Still, when exercising those enumerated powers, Congress must be mindful of other constitutional restraints, such as those flowing from the Second Amendment, the Fifth Amendment's Due Process Clause, and principles of federalism. Congress invoked its tax power when enacting the NFA. Congress has relied on the Commerce Clause as a constitutional basis for GCA provisions restricting the manufacture, import, sale, transfer, and possession of firearms, and the Supreme Court has reviewed a number of these regulations. In District of Columbia v. Heller , the Supreme Court held that the Second Amendment guarantees an individual right to possess firearms for historically lawful purposes. Amendment."
Firearms regulation is an area of shared authority among federal, state, and local governments. Individual states have enacted a diverse range of laws relating to the possession, registration, and carrying of firearms, among other things. Federal law establishes a regulatory framework for the lawful manufacture, sale, and possession of firearms at the national level. The federal framework generally serves as a floor for permissible firearm use and transactions, leaving states free to supplement with additional restrictions so long as they do not conflict with federal law.
Federal laws regulating firearms date back roughly a century, and over time lawmakers have established more stringent requirements for the transfer, possession, and transportation of firearms. The two principal federal firearms laws currently in force are the National Firearms Act of 1934 (NFA) and the Gun Control Act of 1968 (GCA), as amended. The NFA was the first major piece of federal legislation regulating the sale and possession of firearms. Through a taxation and registration scheme, the law sought to curb the rise of violence connected to organized crime by targeting the types of weapons that (at the time of passage) were commonly used by gang members. Congress passed the GCA in the wake of the assassinations of Dr. Martin Luther King Jr. and Senator Robert Kennedy to prevent firearm possession by prohibited persons and to help law enforcement stem increasing crime rates. The GCA is a complex statutory regime that has been supplemented regularly in the decades since its inception. Broadly speaking, the GCA, as amended, regulates the manufacture, transfer, and possession of firearms, extending to categories of weapons that fall outside the scope of the NFA. In general terms, the GCA sets forth who can—and cannot—sell, purchase, and possess firearms, how those sales and purchases may lawfully take place, what firearms may lawfully be possessed, and where firearm possession may be restricted. The Brady Handgun Violence Prevention Act amended the GCA to require a background check for many, but not all, firearms transfers.
Numerous constitutional considerations may inform congressional proposals to modify the current framework for regulating firearms sales and possession. Although Congress has broad constitutional authority to regulate firearms, any firearm measure must be rooted in one of Congress's enumerated powers. In enacting firearms laws, Congress has typically invoked its tax, commerce, and spending powers. For example, the NFA invokes Congress's tax power, and many GCA provisions invoke Congress's commerce power. Additionally, Congress has used its spending power to incentivize states, through offering grant money, to provide comprehensive records to the FBI's National Instant Background Check System (NICS).
When exercising its enumerated powers, Congress nevertheless must be mindful of other constitutional restraints. Congress may want to look to the Supreme Court's Second Amendment jurisprudence—chiefly, District of Columbia v. Heller—when imposing any firearm restriction. In Heller, the Supreme Court held that the Second Amendment provides an individual right to keep and bear arms for lawful purposes. Further, the Due Process Clause of the Fifth Amendment limits Congress's ability to deprive a person of any constitutionally protected interest, such as Second Amendment firearms rights, and rights in property, such as firearms and accessories. Moreover, when enacting measures seeking to limit state firearm schemes, Congress may want to consider the federalism limits inherent in the Constitution's system of dual sovereignty, such as the anti-commandeering doctrine.
These constitutional considerations are relevant to the scope of legislation that the 115th and 116th Congresses have considered to amend the existing federal statutory framework of firearms regulation. Among other things, such legislation has focused on issues arising from the dissemination of 3D-printed and untraceable firearms, gaps in the collection of records for background checks of prospective firearm purchasers, restrictions on certain types of firearms and accessories, possession of firearms by the mentally ill, interstate reciprocity for lawful concealed carry of firearms, and laws permitting courts to order that firearms be temporarily removed from persons deemed to be a risk to themselves or others.
