JUDGMENT

Boys, J. - This defendants' appeal arises out of a suit for possession instituted under the following circumstances, Kalidin executed a mortgage dated 13th June 1873, in favour of defendants 1 to 10, who later brought a suit on the basis of their mortgage, and brought some property to sale. A share was included in the sale which was not included in the mortgage or in the decree. The decree-holder himself purchased and obtained possession. The present suit was brought by the judgment-debtor to recover the excess sold,

2. The trial Court gave the plaintiff's a decree, and the lower appellate Court dismissed the defendants' appeal. The defendants again appeal to this Court.

3. It has been again contended for the appellants here, as it was in the. Courts below, that the suit is barred by Section 47, Civil P. C, by Order 21, Rule 92, Civil P.C., and by limitation. For the respondents, in addition to contesting that none of these pleas barred the suit, it has been further urged that the sale was in fact a nullity. We will proceed to consider first the plea of the appellants based on Section 47, Civil P.C.

4. A large number of cases have been quoted to us on behalf the appellants in support of their proposition that Section 47 constitutes a bar to the present suit. It is, however, unnecessary for us to consider those cases in detail, for they can all be swept aside by one general criticizm which covers them all, and that is that no case has been quoted to us in which the question has been definitely considered whether an auction-purchaser can be held to be the representative of a decree-holder for the purposes of Section 47, and in which that question has also-been definitely answered in the affirmative. The most that it has been possible to show on behalf of the appellants is that there have been some cases in which it was held that a proceeding came within Section 47 to which only the judgment-debtor and the auction-purchaser were parties, but the effect of the absence of the decree-holder from the proceedings was not considered. It is only necessary to add that we ourselves can find no adequate reason of any sort for treating the auction-purchaser as a representative of the decree-holder, at any rate in the present proceeding. We hold, therefore, that Section 47 did not constitute a bar to the present suit.

5. Next, does Order 21, Rule 92 constitute a bar? It is clear that there are questions in which an auction-purchaser is involved which may come within the bar of Rule 92; but it is not all questions in which an auction-purchaser is involved that come within that bar, but only those which come within the scope of one or other of the Rules 89, 90 and 91. Of these three rules, we need only consider Rule 90. It will be noted that, when setting out above the facts of this case we did not state at what stage the mistake crept in. For the appellants it was admitted that the property which was included in the decree was only the property which was included in the mortgage. There was, therefore, no mistake in the decree. In the sale certificate a share was included which was not included in the mortgage or in the decree. But we have no information at all as to whether the mistake first crept in, in the sale-certificate or whether it first appeared in the application for execution or whether it first appeared in the sale-proclamation. We specially and in very clear terms asked counsel for the appellants what evidence there was to indicate at which of these three stages the mistake first occurred, and he told us in equally unmistakable terms that there was no evidence available-documentary or oral-on this point, and it was impossible to say from the record when and where the mistake occurred. At a later stager.the case, when endeavouring to establish that the suit was barred by Rule 92, counsel found himself in some difficulty. Of the three Rules 89, 90 and 91, he could only rely upon Rule 90, and in examining the phraseology of that
