Barely 24 hours after a federal judge upheld Connecticut gun control laws passed in the wake of the Newtown school massacre, the lawyer who challenged the constitutionality of the measures on behalf of gun owners notified the U.S. Circuit Court of Appeals for the Second Circuit of his clients’ intent to keep fighting.

Attorney Brian Stapleton, who practices in both Stamford and White Plains, N.Y., represents the plaintiffs, which include the Connecticut Citizen’s Defense League and Coalition of Connecticut Sportsmen. Their lawsuit names Gov. Dannel Malloy and other state officials and specifically objects, among other things, to the state’s decision to add more than 100 firearms to the state’s assault weapons ban and restrict the sale of large-capacity ammunition magazines.
