Courthouse Steps Decision: Smith & Wesson Brands, Inc. v. Estados Unidos Mexicanos

In Smith & Wesson Brands, Inc. v. Estados Unidos Mexicanos, Mexico brought suit against several U.S. gun manufacturers, including Smith & Wesson. It alleged, among other things, that they were in part liable for the killings perpetrated by Mexican cartels. Mexico argued that the gun manufacturers know the guns they sell are/may be illegally sold to the cartels and thus are the proximate causes of the resulting gun violence.The manufacturers argued that they were immune from such suits under the U.S. Protection of Lawful Commerce in Arms Act (PLCAA), which protects U.S. gun manufacturers from certain types of liability, though not universally, as it contains a predicate exception for manufacturers who knowingly violate applicable federal (and potentially international) law.The Supreme Court heard oral arguments on March 4, 2025. On June 5, 2025, the Court issued a unanimous opinion authored by Justice Kagan, ruling that the PLCAA did prevent the suit from moving forward. Justices Thomas and Jackson both filed concurrences.Join us for a Courthouse Steps program where we will discuss the decision and the potential ramifications of the case.Featuring:Joel S.
