Kernrechtsfrage
Whether the federal filing was admissible as an appeal in public law matters or as a subsidiary constitutional complaint.
Extrahierter Entscheid
An appeal in public law matters was inadmissible because tax relief concerns tax remission; the filing was treated as a subsidiary constitutional complaint.
Extrahierte Begründung
Remission of taxes falls under the exclusion of Art. 83 lit. m BGG, so only the subsidiary constitutional complaint remained available.
