Question juridique clé
Whether the cantonal court correctly held the social insurance complaint time-barred because court holidays did not suspend the appeal period.
Solution extraite
The cantonal court was correct: under Nidwalden law, the relevant period did not stop during court holidays in the simplified procedure applicable here.
Motifs extraits
For transitional ATSG cases, cantonal procedural law still governed the start and running of the appeal period. The cantonal court statute applied directly because no special social-insurance rule excluded it; in the simplified procedure, statutory and judicial deadlines do not stop during court holidays.
