Key legal question
Whether the mootness orders and cost awards of the cantonal court violated the appellants' constitutional rights.
Extracted holding
The cost awards were not arbitrary and did not violate the duty to give reasons.
Extracted reasoning
The Federal Court held that the cantonal court could depart from its usual mootness-cost practice because the appellants knowingly triggered a short-lived interim-protection proceeding shortly before an imminent municipal decision. The court may assess whether the interim relief application itself had prospects of success; on the record, no immediate stop was necessary and no prejudicial effect was shown.
