In October, 2013, Supreme Court heard arguments in U.S. vs. Castleman, for which Legal Momentum co-authored an amicus brief. The case centered on whether a gun trafficker who abused the mother of his child should be able to legally buy guns. The amicus brief urged the Supreme Court to uphold federal laws—and those state laws like Tennessee’s—that were enacted to ensure that domestic violence abusers are prohibited from possessing guns. In March, 2014, the Court decided to uphold the provisions of the Violence Against Women Act that prevent abusers from purchasing firearms. Justice Sotomayor cited information from Legal Momentum’s amicus brief in her majority opinion.
