COYLE v. SMITH
In 1910, Oklahoma enacted a law moving its state capital from Guthrie to Oklahoma City. In admitting Oklahoma to the Union, the Congress declared the temporary capital to be Briscoe and that a change to some other location would not occur until 1913.
Does Oklahoma have the power to locate its seat of government when Congress has imposed conditions limiting that location?
Yes. This was congressional overreaching. States are on an equal footing to determine their own location for the seat of government.
