Massachusetts v. Depina considered challenges to Massachusetts statutes that require persons who possess a firearm to: 1) obtain a firearm identification card to possess certain types of firearms (Mass. Gen. Laws ch. 140, § 129B, 129C); and 2) obtain a state license in order to carry a handgun in public (Mass. Gen. Laws ch. 140, § 131). The challenger – convicted of violating these statutes – claimed the laws violate the Second Amendment to the U.S. Constitution based on the U.S. Supreme Court decision District of Columbia v. Heller, 128 S. Ct. 2783 (2008). LCAV joined the Brady Center and other law enforcement and gun violence prevention groups in filing this amicus brief in support of Massachusetts.
