Questione giuridica chiave
Whether the Verwaltungsgericht could declare the cantonal tax appeal inadmissible because the cost advance was not paid within the final deadline.
Decisione estratta
Yes. The second deadline under § 34 Abs. 4 VRPG was a mandatory, non-extendable statutory deadline; because the advance was still unpaid after that deadline, non-entry was lawful.
Motivazione estratta
The appellants were warned of the consequence of default and of the non-extendable nature of the final ten-day period. Their later request for extension and eventual payment did not cure the lateness. No arbitrariness or other constitutional violation was shown.
