The Scouts have a legal claim to the building. The city owns the land it sits on, and have been allowing the Scouts to use it rent-free. Since there was only a hand-shake agreement on the rent-free status to begin with then the city is free to change it at any time. So if the Scouts lose the case then I assume the city has to give them something for the value of the building they're forcing the Scouts to abandon?
I was expecting you.
If the rent deal is invalid, so should the transfer of the land be invalidated...property reverts to the Boy Scouts.
