Questão jurídica principal
Whether the cantonal appellate court violated the right to be heard when treating the extension-order notice as duly served.
Decisão extraída
No violation; the court could rely on the postal delivery information and the duty of a party to ensure service during pending proceedings.
Fundamentação extraída
A missed pickup notice is deemed served when the recipient could reasonably expect a procedural communication; the appellant did not show that the notice was not delivered, and the theoretical possibility of delivery to a third party was insufficient.
