Questão jurídica principal
Whether the cantonal appellate court correctly declined to hear the appeal as late
Decisão extraída
Yes. The appeal was not shown to have been handed to the Swiss post within the deadline, so the non-entry decision stands.
Fundamentação extraída
The appellant did not demonstrate a violation of federal law; the complaint mostly attacked cantonal procedural law, which is not reviewed under Art. 95 ff. BGG. The burden of proving timely exercise of the right lies with the party invoking the time-limited remedy, and the declaration of the representative did not prove timely delivery to the Swiss post.
