Supreme Court dismissed appeal on procedural grounds regarding social insurance appeal filing deadlines. Appeal is a special writ initiating proceedings, not a civil claim subject to specific appeal rules.

The Supreme Court dismissed the appellant's appeal against the appellate court's decision rejecting the appeal against a social insurance office's refusal of disability pension. The appellant argued the appeal functioned as a civil claim, but the court clarified that social insurance proceedings follow a distinct administrative track governed by special procedural rules. Consequently, the appeal was rejected because it was filed after the statutory deadline, as the special writ initiating proceedings does not benefit from the extended timelines applicable to civil claims.
