Key legal question
Whether the subsidiary constitutional complaint remained admissible after the procurement contract had already been concluded
Extracted holding
The complaint had become moot because the appellant no longer had a legally protected interest in overturning the challenged interim order.
Extracted reasoning
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.
