Question juridique clé
Whether the tenant's defect-removal requests were sufficiently substantiated in the cantonal proceedings
Solution extraite
They were not sufficiently substantiated; the broad references to correspondence and general defect lists did not require the court to search the file.
Motifs extraits
Even under the social inquisitorial approach, the parties must identify the decisive facts and link evidence to them; the judge is not required to comb through extensive correspondence.
