Kernrechtsfrage
Whether the guardian appointment was invalid because a recused authority member participated in the decision
Extrahierter Entscheid
The participation of the recused municipal councillor violated the recusal rules and could not be cured on appeal; the appointment decision had to be annulled.
Extrahierte Begründung
A breach of recusal rules is in principle a formal defect requiring annulment. Cure is exceptional and requires a minor violation with excluded influence on the decision. Here the member's participation was decisive for the adoption of the decision, and it could not be assumed the outcome would have been the same without him.
