Which Supreme Court decision involved a state filing a bill seeking to restrain a U.S. game warden from enforcing the Migratory Bird Treaty Act?

The Supreme Court decision involving a state attempting to restrain a U.S. game warden from enforcing the Migratory Bird Treaty Act is the case Missouri v. Holland. This landmark ruling addressed the balance of power between state and federal authority, specifically regarding the management of migratory birds that cross state lines. The court upheld the federal government's treaty power, confirming that the federal law enacted to regulate the hunting of migratory birds was valid and enforceable, despite the state’s objections. This case demonstrated the supremacy of federal law in matters of interstate and international concern, which further solidified the understanding of federal involvement in wildlife management and conservation policies. The ruling established a precedent for federal protection of migratory species under international treaties, thus preventing states from individually undermining or challenging federal regulations aimed at species that do not recognize state boundaries.
