Kernrechtsfrage
Whether the Verwaltungsgericht could declare the cantonal tax appeal inadmissible because the cost advance was not paid within the final deadline.
Extrahierter Entscheid
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.
Extrahierte Begründung
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.
