Question juridique clé
Whether the cantonal court violated the appellant's right to be heard by failing to alert him to the envelope annotations and let him comment before declaring the appeal late.
Solution extraite
Yes. The appellant had to be informed of the handwritten indication of misdelivery on the envelope and allowed to respond before the inadmissibility ruling.
Motifs extraits
The court held that the envelope's handwritten note and the existing filing list created a doubt about the postal sequence that could not be dismissed solely on the postal stamp. Because the appellant was not shown this factual element, his procedural right to comment on decisive evidence was breached.
