Any person whose claim to proprietary rights in any land was not expressly decided by such officer or Court may sue in a Civil Court to establish such claim; and if he can prove that, when proprietary rights in such land were awarded by such officer or Court to other persons, he was entitled to interests therein of the same nature as those upon consideration of which the award was made, the Civil Court may declare him entitled to a proprietary right of such nature and extent in the land as it may deem just.
