Kernrechtsfrage
Whether the filing was admissible as a subsidiary constitutional complaint rather than an ordinary public-law appeal.
Extrahierter Entscheid
The filing had to be treated as a subsidiary constitutional complaint because an ordinary public-law appeal was unavailable in this matter.
Extrahierte Begründung
Tax-remission disputes of the kind at issue fall under the statutory exclusion of the public-law appeal; only constitutional rights could be invoked.
