This case asks the Supreme Court to decide whether 18 U.S.C. 922(g)(8), which bans firearm possession for someone under a civil protective order due to domestic violence, violates the Second Amendment on its face. Petitioner United States argues that the ban does not violate the Second Amendment because the history and tradition of firearm regulations in the United States allow Congress to disarm individuals who are not law-abiding, responsible citizens, such as those subject to civil protective orders. In opposition, Respondent Zackey Rahimi contends that § 922(g)(8) violates the Second Amendment on its face because the Second Amendment protects the firearm rights of all United States citizens and § 922(g)(8) bears no resemblance to any firearm regulations in American history. The outcome of this case will affect the constitutionality of laws that address domestic violence, as well as how future gun regulations will be analyzed.
