Kernrechtsfrage
Whether the cantonal tax court's remand decision was an admissible object of a subsidiary constitutional complaint.
Extrahierter Entscheid
The complaint was inadmissible because the challenged decision was a remand order, not a final or partial decision, and none of the exceptions for interlocutory decisions applied.
Extrahierte Begründung
The remand did not end the proceedings and was therefore an interlocutory decision under the BGG. It concerned neither jurisdiction nor recusal, caused no irreparable legal disadvantage because the taxpayers could challenge the new decision again, and did not allow the Federal Supreme Court to render a final decision itself.
