Questão jurídica principal
Whether the cantonal appeal against the withdrawal decision was time-barred despite a later ordinary mailing of the same decision.
Decisão extraída
The first registered mailing was deemed notified at the end of the postal holding period; the later ordinary mailing did not create a new appeal deadline.
Fundamentação extraída
A registered item not collected is notified by legal fiction on the last day of the holding period. A second notification is generally without legal effect and did not justify reliance on a new deadline.
