Kernrechtsfrage
Whether the subsidiary constitutional complaint remained admissible after the procurement contract had already been concluded
Extrahierter Entscheid
The complaint had become moot because the appellant no longer had a legally protected interest in overturning the challenged interim order.
Extrahierte Begründung
Standing under Art. 115 lit. b BGG requires a current legally protected interest; once the contract was signed, no effective relief against the stay decision remained possible, and no exceptional reason justified review despite loss of interest.
