I’m no attorney, but I would think if you give away property as long as you have a perpetual lease, and are then thrown out, then it seems the scouts should have legal recourse to getting their building back?
I’m sure the Council & BSA attorneys are all over this — I wish I knew more about the details of the agreement, but it sounds to me, an interested layperson, that BSA has a good case.
OTOH, it must be more complicated than that, because (IANAL) I think from b-law that buildings (”improvements”) go with the land, and the land was always owned by the city.
I also recall from b-law that transactions involving real estate must be in writing to be enforceable, which makes me wonder why the details of the contract (if one exists) haven’t been made public.
