Supreme Court of the United States
544 U.S. 528, 125 S.Ct. 2074 (2005)
Inquiries under a takings analysis aim to identify regulatory actions that are functionally equivalent to the classic taking in which government directly appropriates private property or ousts the owner from his domain.
If a government action is found to be impermissible because it fails to meet the public use requirement, or is so arbitrary as to violate due process, it is not allowed and no amount of compensation can authorize it.
