Key legal question
Whether the subsidiary constitutional complaint was admissible and the applicant had standing to challenge the award after contract conclusion.
Extracted holding
The complaint was admissible as a subsidiary constitutional complaint, and the bidder had standing to seek annulment and a declaration of unlawfulness.
Extracted reasoning
The contract was already concluded, so only annulment and a declaration of illegality remained available; as a participant in the tender, the bidder could invoke arbitrariness under Art. 9 BV.
