Kernrechtsfrage
Whether the complaint was admissible regarding the 1997 stamp duties despite the lower court already having allowed the appeal for that year.
Extrahierter Entscheid
The complaint was inadmissible to that extent because the appellant lacked a legal interest in challenging the already favorable part of the lower-court decision.
Extrahierte Begründung
No legal protection interest exists where the lower court has already upheld the party's position on the contested point.
