Key legal question
Whether the CHF 500 fee imposed after partial admission of the tax appeal was arbitrary under cantonal law.
Extracted holding
The fee allocation was not arbitrary; CHF 500 represented only a share of the total costs and could be charged to the taxpayers.
Extracted reasoning
The court held that the fee was fixed taking account of the partial success of the taxpayers, remained modest, and reflected costs inherent in the proceeding. The cantonal authority's practice of not charging the tax administration did not make the result unsustainable.
