Kernrechtsfrage
Whether the subsidiary constitutional complaint was admissible despite the exclusion of ordinary public-law appeal in procurement matters.
Extrahierter Entscheid
The complaint was admissible insofar as it alleged violations of procedural constitutional rights.
Extrahierte Begründung
Although Art. 83 lit. f BGG excluded the ordinary appeal, a subsidiary constitutional complaint was available. Even if merits standing was doubtful, procedural grievances amounting to a denial of justice could still be raised under the 'Star' doctrine.
