Question juridique clé
Whether the appeal to the cantonal court was time-barred despite defective notification of the withdrawal decision.
Solution extraite
The authority failed to prove an effective notification to the represented insured; the appeal period therefore did not run, and the cantonal court had to enter into the case.
Motifs extraits
The burden of proving notification and its date lies with the authority. Without proof of delivery to the insured or an authorized third party, one cannot infer valid notification. The court also rejected the view that the insured had a duty to react earlier based solely on the withdrawal of the pension, and found the cantonal court's assumptions about her illiteracy and family help arbitrary.
