Kernrechtsfrage
Whether the subsidary constitutional complaint was admissible against the cantonal decision on costs and expenses in a public procurement case
Extrahierter Entscheid
The complaint was admissible in principle because the dispute concerned only accessory costs and did not raise a question of principle on the merits.
Extrahierte Begründung
In procurement matters, the same remedy generally applies to accessory issues as to the main decision; here the appellant itself conceded that no question of principle arose, so the subsidiary constitutional complaint was the proper avenue.
