Key legal question
Whether the cantonal court's refusal to enter into the tax appeal for late payment of the advance was unconstitutional.
Extracted holding
No. The court was entitled to dismiss the appeal after the non-extendable final deadline expired; the late payment did not cure the default.
Extracted reasoning
The complainants had been granted the statutory final 10-day deadline with an express non-entry warning. They could not expect an extension merely by citing financial difficulties. The filing on the last day was not a substantiated request for legal aid, and the cantonal court's decision was neither arbitrary nor overly formalistic.
