PLCAA reshaped firearm litigation by creating a federal threshold question about which gun-industry lawsuits may proceed.
Congress enacted PLCAA as Public Law 109-92
The law was approved October 26, 2005 and codified primarily at 15 U.S.C. §§ 7901–7903.
The statute bars a defined category of actions
It does not create universal immunity from every lawsuit. The statute defines “qualified civil liability action” and lists exceptions.
Predicate-exception litigation became important
One exception concerns actions in which a seller or manufacturer knowingly violated a state or federal statute applicable to the sale or marketing of the product and the violation was a proximate cause of harm.
The Supreme Court revisited PLCAA in 2025
In Smith & Wesson Brands v. Estados Unidos Mexicanos, the Court held Mexico’s complaint did not plausibly plead the aiding-and-abetting theory needed to fit the asserted exception.
Where this fits in the larger timeline
This event is part of the History of Gun Laws in America series. Federal firearm law developed incrementally through constitutional amendments, taxation and commerce statutes, criminal prohibitions, background-check legislation and modern Second Amendment decisions.
