Kernrechtsfrage
Whether the cantonal court correctly found the appeal against the IV decision to be late
Extrahierter Entscheid
No. The administration had not proven earlier service of the uninsured decision; the appeal period started on 2013-10-29 and the appeal of 2013-11-25 was timely.
Extrahierte Begründung
The burden of proving service and its date lies with the administration. For uninsured mail, doubts are resolved in favor of the recipient. The cantonal court violated this rule by assuming prior receipt without proof.
