Questione giuridica chiave
Whether the June 2001 agreement was a lease or a building-right contract
Decisione estratta
The agreement was correctly qualified as a lease under Art. 253 OR; the antenna constructions and ownership clause did not make it a building-right contract.
Motivazione estratta
A lease may allow the tenant, with consent, to erect installations on the leased land; removal obligations at lease end do not transform the contract into a building-right arrangement.
