A federal judge upheld Colorado gun restrictions that were enacted in response to 2012 mass shootings, saying Thursday that limiting the size of ammunition magazines and expanding background checks on firearm purchases are constitutional acts.
But gun-rights advocates who sued the state to overturn the laws called the ruling only the first round and said they planned to appeal.
In a 50-page decision, U.S. District Judge Marcia Krieger said both laws don't infringe on individuals' right to bear arms. The judge further said that limiting magazine sizes doesn't obstruct individuals' ability to protect themselves, and that the expansion of background checks to include firearms sold online and between private parties "is no more severe" than the requirements already in place for commercial sales before the new law.
Gun rights advocates and county sheriffs filed the lawsuit to overturn the laws, which Democrats passed last year without Republican support.
Opponents of the laws criticized them as unenforceable. Krieger dismissed that argument, saying it didn't apply to whether the laws were unconstitutional.
