The opening brief has been filed at the U.S. Court of Appeals in the case of Kachalsky v. Cacace. The appeal challenges the constitutionality of New York’s discretionary handgun-licensing scheme. Currently, the state requires “proper cause” for the issuance of a license to carry a handgun, creating a prior restraint on the fundamental right to bear arms under the Second Amendment and violating equal protection under the 14th Amendment.
