Question juridique clé
Whether the complaint to the cantonal court was filed within the deadline and whether the debtor’s right to be heard was violated by the appellate court’s timeliness inquiry.
Solution extraite
The appellate court was entitled to examine timeliness; no protected interest required further hearing on the track-and-trace result, because the debtor knew when he collected the document.
Motifs extraits
The date of collection merely clarified a fact known to the debtor himself, so no separate right to comment arose.
