Kernrechtsfrage
Whether the appeal was admissible under the Federal Supreme Court Act despite being directed against interim decisions in tax-relief proceedings.
Extrahierter Entscheid
The ordinary public-law appeal was unavailable; only a subsidiary constitutional complaint could be considered.
Extrahierte Begründung
The challenged rulings concerned interim decisions in tax-relief proceedings, which fall under the exclusion of Art. 83 lit. m BGG regardless of whether the attacked decision is final or interim.
