Key legal question
Whether the appeal was admissible regarding cantonal and communal taxes despite an unreasoned filing before the cantonal court.
Extracted holding
No. The filing lacked the required reasoning, and the complaint did not show arbitrariness or a constitutional violation in the cantonal court's refusal to set a cure period.
Extracted reasoning
The appellant failed to meet the federal substantiation requirement for constitutional complaints; the cantonal court could treat the appeal rules as special and not apply the cure provision.
