Thank you - I read the link provide & understood somethe gist is if we are hold over - not budge (not give up building) - the city goes to court to get a judgement of possession and then we get tell the judge why we believe that the group owns the building and the judge decides.
Ways it might be decided - yes the group built believing they had a lease of land & building is groups - city you're stuck with them, or, 2. yes group built building - city pay them something for it, then group go find somewhere else, or, 3. group leave take your building or leave it but if left it'll be city or, 4. group you just go no building, no money, you're gone.
