WASHINGTON — A federal judge has thrown out a lawsuit challenging new reporting requirements for gun dealers that the Obama administration says are needed to help staunch the flow of powerful rifles to violent Mexican drug gangs.
Ruling in a suit brought by gun dealers and backed by the National Shooting Sports Foundation as well as the National Rifle Association, U.S. District Judge Rosemary Collyer of the D.C. District ruled Friday that the new rules were a reasonable law enforcement tactic.
The suit stemmed from reporting requirements issued in July that required about 8,500 gun dealers in Arizona, California, New Mexico and Texas to alert federal officials to sales of multiple semiautomatic rifles to the same person within five business days.
