Kernrechtsfrage
Whether the appeal against the remand decision was admissible.
Extrahierter Entscheid
Yes. The remand decision was a challengeable interim decision because the authority would otherwise suffer irreparable procedural prejudice.
Extrahierte Begründung
The lower court did not finally end the case and factual determinations were not purely arithmetic; nevertheless, the tax authority could not later challenge an end decision aligned with the superior court's instructions.
