Questione giuridica chiave
Whether the complaints against the dismissal of the appeal and the refusal to restore the deadline were admissible before the Federal Supreme Court.
Decisione estratta
The public-law appeal was admissible; the subsidiary constitutional complaint had no room. The Court did not enter into the substantive planning requests because the cantonal court had not examined them.
Motivazione estratta
The challenged cantonal decision concerned only non-entry and refusal of restoration; the appellants could invoke federal law, including Art. 29(1) BV, against formal denial of justice and excessive formalism.
