Key legal question
Whether the tenant was released from rent obligations under Art. 264 CO by proposing a substitute tenant.
Extracted holding
No release: the proposed substitute tenants were not willing to take over the lease on the same conditions, because they demanded repairs and cleaning beyond the tenant's rights.
Extracted reasoning
A substitute tenant must be ready to assume the lease in the same state and on the same terms. Persons who require restoration or cleaning are not willing to take over on the same conditions.
