Question juridique clé
Whether the cantonal appeal was filed within the statutory time limit despite the contested postal delivery method.
Solution extraite
The decision was deemed served when it was placed in the representative's mailbox on 2006-10-03; the later attempted postal correction did not postpone service.
Motifs extraits
Under cantonal law, written service did not require registered mail. Once the decision entered the addressee's sphere of control, the addressee could take notice of it. The unilateral attempt to obtain a later registered delivery could not alter the already completed service or create protected reliance.
