Questão jurídica principal
Whether the Federal Court appeal against the cantonal tax court's remand order was admissible.
Decisão extraída
The appeal was admissible because the cantonal decision was an independently appealable interlocutory decision on functional jurisdiction.
Fundamentação extraída
The lower court's order did not end the proceedings and effectively refused to exercise the jurisdiction previously confirmed by the Federal Court; such a self-contained procedural decision is immediately reviewable.
