Question juridique clé
Whether the appeal against the cantonal decision was inadmissible because the advance of costs was not paid within the deadline after registered notice.
Solution extraite
The lower court could treat the advance-of-costs request as duly notified by fiction after the seven-day holding period; the appellant failed to show arbitrariness in this finding.
Motifs extraits
The postal notice benefit from a rebuttable factual presumption of proper deposit. The appellant did not establish, on the balance of probabilities, that no notice was deposited. The ticket produced did not prove a later departure date.
