Questão jurídica principal
Whether the public-law appeal against a procurement-related cantonal decision was admissible under Art. 83(f) LTF.
Decisão extraída
The public-law appeal was not available because procurement decisions are excluded unless a principle question is raised; none was shown.
Fundamentação extraída
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.
