Questão jurídica principal
Whether the cantonal court correctly held the appeal against the IV decision to be time-barred because service was on 19 January 2007.
Decisão extraída
The date of service on 19 January 2007 was not proven; the filing was therefore timely on the basis of service on 22 January 2007.
Fundamentação extraída
The post confirmation proved delivery of a package to the insurer, but not that it contained the contested decision. Given concrete doubts about the contents, the administration had to prove the content of the shipment. The lower court failed to require that proof and relied on an incomplete factual basis.
