Questão jurídica principal
Whether the federal administrative appeal was admissible against the cantonal court's remand decision
Decisão extraída
The remand decision with binding instructions was treated as an appealable principal/partial decision.
Fundamentação extraída
Because the decision bound the first instance on the merits, it was not merely an interlocutory order; the cantonal tax authority had standing under the Tax Harmonization Act and cantonal law.
