Clause 18(1) provides that where the Cultural Authority is not satisfied that it has identified all of the traditional owners or where is a dispute about ownership, it must refer the matter to the parties concerned to resolve the matter according to customary law and practice or such other means as is agreed to by the parties. Once the traditional owners have been identified in accordance with customary law or practice or such means as have been agreed to, clause 18(2) requires the traditional owners to advise the Cultural Authority.
L'article 18.1 dispose que si l'Autorité culturelle n'est pas certaine qu'elle a identifié tous les propriétaires traditionnels, ou si survient quelque litige au sujet de la propriété, l'Autorité culturelle doit en référer aux parties concernées qui régleront le litige selon la loi et les pratiques coutumières ou par tout autre moyen convenu entre elles.
