A federal judge on Thursday upheld Colorado's new gun-control laws that mandated background checks for all gun sales and limited the capacity of ammunition magazines to no more than 15 rounds.

U.S. District Chief Judge Marcia Krieger issued her 50-page ruling on the 2013 laws after a two-week civil trial in late March and early April in Denver.

The lawsuit was originally filed by plaintiffs including sheriffs, gun shops, outfitters and shooting ranges. Krieger ruled last year that the sheriffs could not sue the state in their official capacities but they could join the lawsuit as private citizens.

Krieger determined that the plaintiffs lacked standing in their lawsuit.
