If, on the other hand, the Government forces you to sell directly to the private developer because the developer has a plan for its own benefit, then there is no public trust created and thus I do not believe that there is any way to say that the taking is for a "public use."
I have to agree that this is not constitutional. I had thought this was just another economic development plan implemetation, but it isn't. I would join the dissent in this one.
There is no way to force that except by the methods of the Godfather. I don't believe we have descended to horse heads already.
