order notifying the vacancy then and there, would result in the loss of right to the aggrieved person of challenging the notifying the vacancy itself, in a revision against the final order of allotment. It has only clarified that even the order notifying the vacancy could be immediately and independently challenged. The High court, in our view has misunderstood the effect of the decision of this court in Ganpat Roy’s case and has not kept in mind the general principles of law governing such a question as expounded by the Privy Council and by this Court. It is nobody’s case that there is anything in the Act corresponding either to Section 97 or to Section 105 (2) of the Code of Civil Procedure, 1908 precluding a challenge in respect of an order which ultimately leads to the final order. We overrule the view taken by the Allahabad High Court in the present case and in Smt. Kunj Lata v. Xth Additional District Judge, Kanpur Nagar and others (supra) that in a revision against the final order, the order notifying the vacancy could not be challenged and that the failure to independently challenge the order notifying the vacancy would preclude a successful challenge to the allotment order itself. In fact, the person aggrieved by the order notifying the vacancy can be said to have two options available. Either to challenge the order notifying the vacancy then and there by way of a writ petition or to make the statutory challenge after a final order of allotment has been made and if he is aggrieved even thereafter, to approach the High Court. It would really be a case of election of remedies.”
