Question juridique clé
Whether the lease was validly terminated early under Art. 285 para. 1 CO for persistent contractual breach regarding turnover.
Solution extraite
Yes. The turnover clause was an essential usage term; after written warning, the tenant failed to comply immediately and the early termination was effective.
Motifs extraits
Art. 285 CO applies by analogy to breaches of use-related contractual duties. The tenant undertook to achieve 90,000 CHF monthly turnover; after a written warning, he did not correct the shortfall in January and February 2009. The warning required immediate action, and the landlord proved the protest remained ineffective.
