The federal baseline: PLCAA
Congress passed the Protection of Lawful Commerce in Arms Act in 2005 in response to a wave of lawsuits brought by cities and shooting victims against firearm manufacturers and dealers. The law generally bars civil suits against members of the gun industry when their products are later misused to commit crimes. Backers said it was needed to keep a lawful industry from being regulated through litigation; critics said it gave gunmakers a uniquely broad shield not available to other industries.
The exceptions in the law
PLCAA is not absolute. It allows suits in certain situations, including cases involving defective products, breach of contract, and what the statute calls a 'predicate exception' — claims that a manufacturer or seller knowingly violated a state or federal law applicable to the sale or marketing of firearms. Much of the current legal fight centers on what counts as a qualifying state law under that exception.
What states are doing
Starting with New York in 2021, at least nine states — including California, New Jersey and Illinois — have enacted statutes that create civil liability for industry members whose sale, manufacturing or marketing practices are alleged to endanger public safety. Supporters argue these laws are precisely the kind of firearm-specific statutes PLCAA's predicate exception contemplates. The gun industry argues the laws are designed to sidestep PLCAA and impose liability the federal statute was meant to prevent.
The New York case
Gun industry groups challenged New York's 2021 statute in federal court, arguing it was preempted by PLCAA and violated other constitutional protections. Lower courts allowed the law to stand. On June 15, 2026, the U.S. Supreme Court declined to take up the industry's appeal, leaving the New York law in place without setting a nationwide precedent on the broader question.
Arguments for allowing the suits
Proponents say victims of gun violence and the public agencies that respond to it deserve a legal remedy when industry conduct — such as marketing practices or distribution decisions — contributes to harm. They argue states have traditionally regulated dangerous products through tort law and that PLCAA's exceptions were written to preserve that role. They also contend the threat of litigation can encourage safer industry practices.
Arguments against allowing the suits
Opponents argue the state laws effectively nullify a federal statute Congress passed to prevent exactly this kind of litigation. They warn that broad public-nuisance theories can hold lawful businesses responsible for the criminal acts of third parties, and that defense costs alone could drive smaller dealers and manufacturers out of business. Some also raise Second Amendment concerns, arguing that heavy civil liability indirectly burdens lawful firearm commerce.
What's still unsettled
Because the Supreme Court has not ruled on the merits, the underlying legal question — whether state laws like New York's fit within PLCAA's predicate exception — remains open. Lower courts in different circuits could reach different conclusions as more states pass similar measures and more suits are filed. Voters weighing the issue are essentially being asked where the line should fall between federal protection of the industry and state authority to create avenues for civil accountability.
