Question juridique clé
Whether the cantonal court could reject the appeal as late despite an incorrect remedy instruction stating a 30-day deadline.
Solution extraite
The court held that the appellant could not rely on the faulty instruction because his lawyer could have recognized the correct 20-day deadline from the applicable cantonal procedural law.
Motifs extraits
Trust protection does not assist a legally represented party when counsel could identify the error by consulting the statutory text; here the Uri procedural rules clearly provided a 20-day period, and an out-of-canton lawyer is expected to know or consult the basic procedural law.
