Key legal question
Whether the public-law appeal against a procurement-related cantonal decision was admissible under Art. 83(f) LTF.
Extracted holding
The public-law appeal was not available because procurement decisions are excluded unless a principle question is raised; none was shown.
Extracted reasoning
The case concerned public procurement, but the appellants admitted that no question of principle was involved. Their reliance on the Market Internal Act did not avoid Art. 83(f) LTF because that provision expressly links to procurement rules.
