Key legal question
Whether the federal complaint was admissible only as a request for annulment and declaration of unlawfulness after the contract had already been concluded.
Extracted holding
Because the contract with the selected competitor had already been signed, only annulment of the cantonal appeal decision and a declaration of unlawfulness of the award could still be sought; the complaint was admissible to that extent.
Extracted reasoning
Under the Binnenmarkt Act, once execution has occurred, the legal remedy is limited to declaratory relief; the appellant remained entitled to challenge the cantonal decision.
