Question juridique clé
Whether the cantonal court's partial allocation of procedural costs and reduction of party compensation was arbitrary under cantonal procedural law.
Solution extraite
The cost order was not arbitrary; the appellants partly caused additional proceedings, and the cantonal court had broad discretion under §§ 20(3) and 21(1) VPO.
Motifs extraits
The appellants' arguments were largely unsuccessful and helped trigger an inspection; given the 'as a rule' and 'may' wording, the court could depart from strict loser-pays logic. The reduced party compensation was also justified because the appellants' submissions did not affect the outcome.
