Key legal question
Whether the cantonal court violated the right to be heard by not further notifying the appellants after their appeal deadline expired.
Extracted holding
No. The appellants were given a filing deadline; because the postal notice was not collected, the authorities were not required to take additional steps, and the cantonal court even examined the appeal despite the missing brief.
Extracted reasoning
No procedural violation arose from the chosen service method. The constitutional guarantee did not oblige the court to contact the appellants again after the deadline had passed.
