Western states hold roughly 350 million acres of federal public lands, sparking ongoing disputes over whether the Equal Footing Doctrine requires the federal government to transfer those lands to state control. The doctrine holds that states admitted after 1789 join the Union with the same sovereignty and powers as the original 13, even though the Constitutional Convention explicitly rejected language requiring equal footing.
Congress nonetheless included equal footing language in virtually every state admission act. The Supreme Court constitutionalized the principle in Pollard''s Lessee v. Hagan (1845), ruling that new states own navigable waterway beds just like original states. In Coyle v. Smith (1911), the Court struck down a congressional requirement dictating where Oklahoma could locate its capital, holding that Congress cannot control such core sovereign functions. However, the doctrine applies only to sovereign powers, not to economic resources or federal property. Courts have repeatedly rejected claims that equal footing requires the federal government to hand over public lands in Western states like Nevada, Utah, and New Mexico.
