Key legal question
Whether the tenant was released under Art. 264 OR by proposing a substitute tenant through an uncollected registered letter
Extracted holding
No. A substitute-tenant notice that never came to the landlord's actual knowledge and was returned uncollected did not release the tenant, especially because the tenant then took no further steps to bring the proposal to the landlord's attention.
Extracted reasoning
Art. 264 OR requires that the tenant actually present a suitable substitute tenant; in good faith, the tenant must do more than send one letter when the first notice is returned unopened. The proposed substitute tenant also ceased to be available during the relevant review period.
