Key legal question
Whether the appeal to the Federal Supreme Court was admissible against the cantonal decision.
Extracted holding
The challenged cantonal decision was neither a final decision nor a separately appealable partial decision; it was an interim decision.
Extracted reasoning
The tax assessment proceedings were not concluded because the remand left part of the matter open. The disputed points concerned only individual aspects of one tax legal relationship and could not be appealed in isolation under the purpose of the law.
