Questão jurídica principal
Whether the cantonal court could deem the registered letter notifying the defect-curing order properly served despite the appellant's denial of receiving an arrival notice.
Decisão extraída
Yes. The factual presumption that the postal notice was deposited correctly was not shown to be arbitrary, so service was deemed to have occurred after the seven-day holding period.
Fundamentação extraída
A rebuttable presumption applies that postal staff properly inserted the pickup notice. The appellant offered only a general hypothesis of postal error, insufficient to overturn the cantonal findings under the arbitrariness standard.
