Kernrechtsfrage
Whether putting the restaurant into free management amounted to a sublease requiring landlord consent.
Extrahierter Entscheid
Yes. A free-management arrangement allowing a third party to exploit the leased premises is treated, by analogy, as subletting and requires the landlord's consent.
Extrahierte Begründung
The lease-sublease concept in Art. 262 CO is interpreted broadly; although Art. 262 CO speaks only of sublease, a commercial free-management arrangement similarly transfers use of the premises to a third party for remuneration and therefore falls within the consent requirement.
