On October 4, 2024, the Supreme Court agreed to hear an important case about proximate cause and aiding-and-abetting liability. This was a victory for WLF, which filed a brief supporting the cert petition. 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 explained 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 detailed the problems with the First Circuit’s aiding-and-abetting holding.
