Questão jurídica principal
Whether the cantonal court could charge the taxpayers with procedural costs despite their success on the withholding-tax merits.
Decisão extraída
Yes. The taxpayers had caused unnecessary proceedings by presenting contradictory explanations about support payments and childcare compensation, so costs could be imposed on them despite success.
Fundamentação extraída
Under Art. 144 DBG and the analogous rules, an award of costs against the winning party is allowed when that party would have prevailed earlier with proper conduct or when it obstructed proceedings. The taxpayers' inconsistent submissions justified the cost allocation.
