Questione giuridica chiave
Whether the lease termination was invalid because the default notice under Art. 257d CO mentioned the wrong address
Decisione estratta
The default notice was sufficiently intelligible under the trust principle; the wrong address did not render it void.
Motivazione estratta
The law sets no special formal requirements for the wording of a default notice under Art. 257d CO beyond clarity of the unpaid amount and the lease concerned. The tenant had not shown any real confusion about the leased premises, so the cantonal court applied Art. 257d CO arbitrarily.
