Question juridique clé
Whether the appeal against the cantonal cost award was admissible
Solution extraite
The appeal was not admissible because the appellants did not properly substantiate a constitutional arbitrariness complaint against a cost award within the tariff limit.
Motifs extraits
The challenged amount fell within the cantonal tariff. The appellants merely compared another case without showing why the present award was gravely disproportionate; such a complaint did not satisfy the heightened reasoning requirement for arbitrariness review.
