The lawsuit filed by Mexico against US gun manufacturers has faced a setback as a US judge dismissed a significant portion of the case [f1cb126c]. US District Judge Dennis Saylor in Boston ruled that there were jurisdictional problems with the claims against six out of the eight companies named in the lawsuit [f1cb126c]. The dismissed companies include Sturm, Ruger, Glock, Barrett Firearms Manufacturing, Colt's Manufacturing Company, Century International Arms, and Beretta USA [f1cb126c]. The judge's decision narrows the scope of the lawsuit, which sought $10 billion in damages and aimed to hold the gun manufacturers accountable for the flow of firearms across the US-Mexico border [f1cb126c].
