that it can be disregarded by any court or authority and one where it has to be actually set aside before it can cease to have legal effect. An alienation made in excess of power to transfer would be, to the extent of the excess of power, invalid. An adjudication on the effect of such a purported alienation would be necessarily implied in the decision of a dispute involving conflicting claims to rights or interests in land which are the subject matter of consolidation proceedings. The existence and quantum of rights claimed or denied will have to be declared by the consolidation authorities which would be deemed to be invested with jurisdiction, by the necessary implication of their statutory powers to adjudicate upon such rights and interests in land, to declare such documents effective or ineffective, but, where there is a document the legal effect of which can only be taken away by setting it aside or its cancellation, it could be urged that the consolidation authorities have no power to cancel the deed, and, therefore, it must be held to be binding on them so long as it is not cancelled by a court having the power to cancel it. In the case before us, the plaintiff's claim is that the sale of his half share by his uncle was invalid, inoperative, and void. Such a claim could be adjudicated upon by consolidation courts.”
