Kernrechtsfrage
Whether the subsidiary constitutional complaint was admissible in the public procurement dispute
Extrahierter Entscheid
The complaint was admissible only as a subsidiary constitutional complaint, not as an ordinary public law appeal, because no question of principle was shown.
Extrahierte Begründung
The applicant did not establish the statutory conditions for an ordinary public law appeal in procurement matters, but could invoke constitutional rights through the subsidiary complaint.
