The US Supreme Court unanimously dismissed Mexico's lawsuit against American gun manufacturers, citing a US law shielding them from liability. Justice Kagan's opinion stated Mexico hadn't plausibly argued that the manufacturers aided and abetted illegal gun sales to Mexican cartels. Mexico argued the manufacturers' actions fueled drug cartel violence, despite its own strict gun control measures. The court found Mexico's claims insufficient to overcome the legal protections afforded to gun manufacturers.
