The Second Amendment at the Supreme

Court: Challenges to Federal Gun Laws



Updated March 9, 2026

Ratified in 1791, the Second Amendment provides, A well regulated Militia, being necessary to the
security of a free State, the right of the people to keep and bear Arms, shall not be infringed. For over
two hundred years, the Supreme Court remained largely silent on the scope and meaning of the Second
Amendment.  In a series of relatively recent decisions, however, the Court has provided guidance on the
substance of this constitutional provision.
In 2008, in District of Columbia v. Heller, the Supreme Court held that the Second Amendment protects
an individual right to possess firearms for certain purposes, including at least self-defense in the home.
Two years later, in McDonald v. City of Chicago, the Court determined that the right to bear arms applies
not only to laws imposed by the federal government, but also to laws enacted at the state and local levels.
In 2016, in Caetano v. Massachusetts, the Court in a brief opinion clarified that arms within the
meaning of the Second Amendment encompasses modem  arms, including stun guns, that did not exist at
the time of the founding.
In 2022, the Supreme Court in New York State Rifle & Pistol Association v. Bruen resolved two of the
questions left open by the preceding decisions:
    *  Does the right to bear arms extend beyond the home?
       and
    *  How  are courts to properly analyze purported infringements of this right?
In Bruen, the Court held that the protections of the Second Amendment extend beyond the home
generally to places of confrontation. The Bruen Court also announced the standard to be used in assessing
Second Amendment  challenges to firearm laws: When the plain text ofthe Second Amendment covers the
regulated conduct, the Constitution presumptively protects it; to justify a regulation of that conduct, the
government must demonstrate that a challenged law is consistent with the Nation's historical tradition of
firearm regulation.
Following Bruen, plaintiffs filed a number of legal actions contesting various federal and state firearm
laws. Some of these cases involved challenges to long-standing provisions of the federal Gun Control Act
prohibiting certain categories of individuals from possessing firearms. In one such case, United States v
