William O. Douglas,
United States Tennessee Valley Authority v…
“ The United States no more than a state can be excused from paying just compensation measured by the value of the property at the time of the taking merely because it could destroy that value by appropriate legislation or regulation. But we have here a unique situation. The power of eminent domain which respondent seeks to have reflected in the valuation is largely unexercised and need not be reflected in the measure of compensation if the state which conferred the privilege were the taker of the lands. ”
