Question juridique clé
Whether the public law appeal was admissible despite the contract already being concluded
Solution extraite
The appeal was admissible as a public law appeal, and the appellant retained a legal interest in a declaration of unlawfulness under the Market Act.
Motifs extraits
The matter was governed by cantonal procurement law, so administrative appeal was unavailable; the awardee's contract having been signed did not extinguish the appellant's interest in a declaration of unlawfulness.
