On November 27, 2024, WLF filed an amicus brief urging the Supreme Court to reverse a controversial First Circuit decision about proximate cause and aiding-and-abetting liability. Splitting from other courts of appeals and state courts of last resort, the First Circuit held that Mexico could sue firearms manufacturers for allegedly causing the drug-cartel violence in Mexico. WLF’s brief explains why the First Circuit’s decision conflicts with Supreme Court precedent on proximate cause and violates the firearms manufacturers’ due-process rights. The brief also details the problems with the First Circuit’s aiding-and-abetting holding.
