Question juridique clé
Whether the landlord validly set a payment deadline and threatened termination under Art. 257d CO.
Solution extraite
The notice period and termination warning were validly communicated; the tenant did not show a breach of Art. 257d CO.
Motifs extraits
The Federal Court deferred to the lower court's factual finding that the pickup notice was placed in the tenant's mailbox. Challenges to the evidentiary assessment were inadmissible, and once the notice was deemed communicated, the notice was received after the seven-day collection period.
