US Supreme Court Rejects Missouri Law Blocking Federal Gun Enforcement

The U.S. Supreme Court declined to hear Missouri's appeal to revive the Second Amendment Preservation Act, a Republican-backed law aimed at preventing enforcement of certain federal gun laws in the state. Lower courts had previously ruled the law unconstitutional, citing the Supremacy Clause, which establishes federal law as supreme over conflicting state laws. The Missouri law imposed fines on police officers who enforced federal gun regulations deemed by the state to violate the Second Amendment, including rules on firearm possession by domestic violence offenders and weapons registration. The Biden administration challenged the law, arguing it undermined federal authority and disrupted cooperative law enforcement efforts, while the Trump administration balanced its support for gun rights with maintaining federal oversight. The Supreme Court's refusal to intervene maintains the lower courts' block on the law, reflecting ongoing tensions between state efforts to assert gun rights and federal enforcement priorities.
