Question juridique clé
Whether the statutory appeal deadline for a social insurance complaint could be extended.
Solution extraite
No. The appeal deadline was a statutory time limit and could not be extended; missing documents could still have been filed later with the complaint.
Motifs extraits
The cantonal court correctly relied on Art. 60(2) in conjunction with Art. 40(1) ATSG. The claimant raised no argument showing a violation of federal law or manifestly incorrect fact-finding.
