Key legal question
Whether the tenant was released from the lease under Art. 264 CO by presenting a substitute tenant and surrendering the premises.
Extracted holding
No. The tenant did not prove an effective and unconditional restitution of the premises, in particular the handover of the keys; merely making the keys available was insufficient.
Extracted reasoning
Art. 264 CO requires clear intent and actual, complete restitution. Where there is disagreement, the tenant must remove ambiguity and place the landlord in full possession, or consign the keys if refused. The burden of proof lies with the tenant under Art. 8 CC. Since no restitution before 1 December 2006 was shown, the tenant remained liable.
