The case concerns Texas-based gun owner and licensed dealer Michael Cargill, who owned two bump stocks before the ban went into effect and later surrendered them to the government. He sued, claiming that the Bureau of Alcohol, Tobacco, Firearms and Explosives lacked the legal authority to implement the prohibition.
The conservative-majority high court issued a major ruling in June 2022 that expanded gun rights, although the legal issues arising from the bump stocks ban are different.
