Questione giuridica chiave
Whether the cantonal department rightly refused to hear the appeal because the cost advance was paid late
Decisione estratta
The non-entry decision was lawful because the appellant had been properly informed of the amount, deadline, and consequences of non-payment, and the payment was late.
Motivazione estratta
Restrictive use of public-interest exceptions under § 79 VRG was not arbitrary; no request for deadline extension or restitution was made; late payment of a cost advance normally justifies non-entry.
