A federal district court judge in Arizona has ruled that a lawsuit filed by the government of Mexico against five Arizona firearm dealers alleged to be engaging in weapons trafficking should be allowed to proceed.

U.S. District Court Judge Rosemary Márquez held that the federal gun industry shield law, the Protection of Lawful Commerce in Arms Act (PLCAA), should not prevent the suit from advancing. She also ruled against the gun dealers’ argument that Mexico lacked standing.
