[4CJ]

In Arizona and other states public utilities may seize federal, state, commericial and private property ("[t]he authority may acquire by lease, purchase or any other means, real property owned by the state or federal government.")

"Before the adoption of the Fourteenth Amendment this power [eminent domain] of the state was unrestrained by any federal authority."
Justice Day, Green v. Frazier , 253 US 233, (1920)

Whether or not the federal government agreed to it, the states could do what they wanted with respect to properties within their borders.

[Non-Sequitur]

Whether or not the federal government agreed to it, the states could do what they wanted with respect to properties within their borders.

And I will ask again for an example which supports your claim. Point out one instance where a state or local government siezed federal property under eminent domain without the prior approval of the federal government.
