Questione giuridica chiave
Whether the appeal against the remand decision was admissible.
Decisione estratta
Yes. The remand decision was a challengeable interim decision because the authority would otherwise suffer irreparable procedural prejudice.
Motivazione estratta
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.
