Key legal question
Whether the appeal was admissible under the tax harmonization rules.
Extracted holding
The appeal was admissible to the extent it sought annulment and reassessment, because the dispute concerned property-gain taxation under the StHG.
Extracted reasoning
Art. 73 StHG allows federal review of final cantonal decisions in matters covered by the StHG; the taxpayers had a protected interest in clarifying the future tax basis.
