Questione giuridica chiave
Whether the cantonal tax authority was entitled to bring an appeal in public law matters against the cantonal court decision.
Decisione estratta
Yes. As the competent cantonal authority under Art. 73 StHG, it could appeal even though the dispute involved the application of cantonal implementing law within the harmonized tax area.
Motivazione estratta
Article 73 StHG grants standing to the competent cantonal authority. Under the new unified appeal system, standing and admissible grounds are distinct; the authority may invoke violations of federal law, including constitutional arbitrariness.
