Kernrechtsfrage
Whether the subsidiary constitutional complaint was admissible and whether the appellant had standing to seek declaratory relief after contract conclusion.
Extrahierter Entscheid
The complaint was admissible only insofar as declaratory relief was sought; the main request for award could not be entertained, but standing existed because the appellant had a real chance of winning and could seek a declaration of unlawfulness.
Extrahierte Begründung
Under the BGG, the ordinary public-law appeal was unavailable; the subsidiary constitutional complaint remained. Despite the already concluded contract, Art. 9(3) BGBM preserves a practical interest in a declaration of unlawfulness for possible damages.
