Kernrechtsfrage
Whether the complaint was admissible against the cantonal decision remanding the tax case for a new decision.
Extrahierter Entscheid
The challenged ruling was an interim decision; the appellant failed to show a non-reparable legal disadvantage or that an immediate final decision would save substantial time or costs.
Extrahierte Begründung
A remand decision is not a final decision under Art. 90 BGG when the lower authority retains discretion. For an appeal against an interim decision, Art. 93 BGG requires a substantiated showing of irreparable disadvantage or immediate finality; this burden was not met.
