Our nation’s highest court has consistently recognized that the Second Amendment is compatible with strong firearm regulations. Despite this, the gun lobby has repeatedly sought to invalidate lifesaving gun safety laws.


There have been two landmark Supreme Court rulings on the Second Amendment in recent years: District of Columbia v. Heller and McDonald v. City of Chicago.

In 2008, the Supreme Court ruled on the Second Amendment for the first time in almost 70 years after Dick Heller sued the District of Columbia over its ban on handguns in the home. The court ruled in Heller’s favor, affirming an individual right to keep handguns in the home for self-defense.

In its decision, authored by Justice Antonin Scalia, the Supreme Court was careful to stress the limited nature of its ruling. Writing for the majority, Justice Scalia noted: “Like most rights, the right secured by the Second Amendment is not unlimited. [It is] not a right to keep and carry any weapon whatsoever in any manner whatsoever and for whatever purpose.”

The Court provided examples of laws it considered “presumptively lawful,” including those which:

The Heller decision was far from the blanket endorsement of unlimited gun rights that the gun lobby hoped it might be. Rather, the last decade of post-Heller litigation has demonstrated that the decision was a limited ruling fully compatible with the many lifesaving gun laws that protect us today.


In 2010, the Supreme Court heard a case challenging Chicago’s handgun ban, one similar to DC’s recently overturned ban. Otis McDonald and three other Chicago residents sued the city over the ban, and because the Heller decision only applied federally, the Supreme Court agreed to hear the case.

In McDonald v. City of Chicago, the Supreme Court held in a 5–4 ruling that the Second Amendment applies to state and local governments in addition to the federal government. While Chicago’s complete handgun ban was overturned, the Court reiterated in McDonald that a wide variety of state and local gun laws are constitutionally permissible.

The McDonald court stated that: “It is important to keep in mind that Heller, while striking down a law that prohibited the possession of handguns in the home, recognized that the right to keep and bear arms is not ‘a right to keep and carry any weapon whatsoever in any manner whatsoever and for whatever purpose.’”


Gun violence costs our nation 40,000 lives each year. We can’t sit back as politicians fail to act tragedy after tragedy. Giffords Law Center brings the fight to save lives to communities, statehouses, and courts across the country—will you stand with us?


The gun lobby has sought to expand the Second Amendment to invalidate almost every gun law on the books, often falsely claiming support from the Supreme Court or the Heller case. Yet despite the explosion of litigation that followed Heller, courts across the country have repeatedly relied on Justice Scalia’s words to decide that essential gun safety laws are constitutional under the Second Amendment.

In siding with the majority of Americans who support sensible gun laws, courts are reinforcing that gun safety laws are not only constitutional—they’re critical to keeping our communities safe and protecting other constitutional rights, like the freedom to safely assemble in public without fear of gun violence.

Since Heller, lower courts have upheld a wide range of gun laws as constitutional, including:

Giffords Law Center has been defending the constitutionality of gun safety laws for over 25 years, filing over 125 amicus briefs in critical cases and helping demonstrate time and again that gun safety laws are entirely compatible with the Second Amendment. Meanwhile, the gun lobby has invested millions to get judges opposed to gun safety laws confirmed to federal courts, including the Supreme Court.
