To nullify any ATF powers by the federal government to regulate intrastate firearm sales in West Virginia

HB 4920, the "Second Amendment Preservation Act," declares federal regulations on intrastate firearm sales within West Virginia invalid, directly affecting West Virginia residents buying, selling, or transferring firearms, accessories, or ammunition within the state. It prohibits the ATF and other federal entities from enforcing rules that restrict these in-state transactions, stating such actions violate both the U.S. and West Virginia constitutions. The bill imposes civil penalties of $50,000 per violation for federal enforcement attempts and requires the West Virginia Attorney General to defend citizens prosecuted federally or sue federal agencies for violations. It also mandates state law enforcement to refuse enforcing federal gun regulations that infringe on Second Amendment rights.
