Questione giuridica chiave
Whether the landlord's termination was invalid because it relied on Art. 266g OR instead of Art. 257f OR.
Decisione estratta
No. A termination based on a clearly described factual basis remains effective if it is justified under another applicable statutory ground.
Motivazione estratta
A mistaken legal qualification does not defeat a unilateral termination where an alternative norm supports it and the tenant suffers no disadvantage from the mislabeling; the prior instance could therefore uphold the termination on Art. 257f OR even though the notice invoked Art. 266g OR.
