A lawyer for a group of gun rights groups and firearm sellers has appealed a Thursday decision by a federal court judge upholding a new Connecticut gun control law as constitutional.

Attorney Brian Stapleton filed a notice of appeal Thursday, just a day after U.S. District Court Judge Alfred Covello concluded that Connecticut’s new ban on certain rifles and ammunition magazines was constitutional.

“The court concludes that the legislation is constitutional. While the act burdens the plaintiffs’ Second Amendment rights, it is substantially related to the important governmental interest of public safety and crime control,” the decision reads.

Stapleton represents the Coalition of Connecticut Sportsmen, Connecticut Citizens Defense League, gun store owners, and individual citizens in their challenge of the gun control law. He appealed the case to the 2nd U.S. Circuit Court of Appeals.
