Missouri v. Holland
Headline: Federal treaty power upheld to protect migratory birds: Court upholds international bird-protection treaty and law, allowing the federal government to regulate and prevent hunting that states alone might otherwise permit.
Holding:
- Allows federal officers to enforce international bird-protection rules inside states.
- Prevents states from using claimed wildlife ownership to block national conservation measures.
- Affirms that treaties can enable federal action on transitory, cross-border environmental harms.
Summary
Background
A bill in equity was filed by the State of Missouri to stop a United States game warden from enforcing the Migratory Bird Treaty Act of July 3, 1918, and regulations made by the Secretary of Agriculture. Missouri said the federal law and treaty interfered with rights reserved to the States by the Tenth Amendment and that the State owned or had a quasi-sovereign interest in birds within its borders. A District Court dismissed the bill, holding the act constitutional. Missouri appealed. The treaty with Great Britain (proclaimed December 8, 1916) and the 1918 law together prohibited killing, capturing, or selling certain migratory birds except as federal regulations allowed.
Reasoning
The Court considered whether a treaty can reach matters states normally regulate. It emphasized that the Constitution gives the national government the treaty power and makes treaties the supreme law of the land. The Justices noted limits exist, but asked whether the Tenth Amendment forbids this treaty. The Court found the State’s claim of exclusive title to wild, transitory birds a weak basis for blocking national action. Many federal laws are carried out inside the States. Because migration crosses borders and extinction threatened food supplies and insect control, the Court concluded national action was necessary and proper in concert with another nation.
Real world impact
The ruling lets the federal government enforce international bird-protection rules inside state borders. It allows nationwide conservation measures even when states claim authority over wildlife. The decision recognizes that treaties can authorize federal responses to cross-border or international environmental problems.
