Questão jurídica principal
Whether the service had to notify each caravan owner individually and whether the hearing defect was cured on appeal.
Decisão extraída
Individual notice was not required because the association represented the members; any defect was cured before the cantonal court.
Fundamentação extraída
All concerned caravan owners were members of the association, and they could participate and be heard in the cantonal proceedings before a court with full review powers.
