Questão jurídica principal
Whether the cantonal court's CHF 400 costs order in the tax-relief dispute was arbitrary.
Decisão extraída
Yes. In the circumstances, imposing costs on the taxpayer was untenable and violated the prohibition of arbitrariness.
Fundamentação extraída
The procedural path was confusing; authorities did not clearly explain how to proceed, and the taxpayer plausibly would have waited for final assessment and avoided unnecessary proceedings if properly informed. Cost allocation was therefore stossend.
