In support of her application for maintenance, however, the appellant swore an affidavit containing a great many allegations which, if they had been established in the suit for dissolution, might have resulted in its dismissal for the allegations, if believed, would have gone some distance towards establishing that the husband had himself been guilty of adultery and, also, of such wilful neglect or misconduct as had conduced to the wife's adultery. In these circumstances the respondent in this appeal objected on the hearing of the application for maintenance to the admission of this evidence concerning his conduct during the latter years of his married life contending that the appellant was precluded by the findings and decree in the suit from presenting such evidence to the Court. In considering the rival contentions on this point, Dean J., who thought the evidence admissible and whom the Full Court thought was in error on this point, referred to the conflicting decisions in Duchesne v. Duchesne [1] and Geyer v. Geyer [2] . In the former case, Pearce J., in circumstances not dissimilar to those of the present case, held that a husband who had allowed a suit for dissolution of his marriage on the ground of his desertion to proceed as an undefended suit was estopped in maintenance proceedings from "asserting matters inconsistent with the decree", and further that he was "for reasons of public policy, prohibited from asserting matters (of which he knew) which would reasonably have been expected, if proved either to provide an effective answer to the petition or to produce a different result at the trial" [3] . With the first proposition there can be no quarrel but it is not contended in this case that the assertion of those facts which the appellant desired to adduce in evidence were inconsistent with the decree in the suit. But the form of the decree is not the sole measure of what issues were then determined and we have no doubt that the decree was conclusive not only as to those issues expressly pronounced upon but also as to any other issue upon which it was necessary for the Court to adjudicate before making a decree in the form in which it did. Moreover, the decree constituted a judgment in rem and conclusively established the new status of the parties to the suit (Bater v. Bater [1] ). But the proposition that the wife, by failing to attempt to show in the suit that her husband had been guilty of adultery or of neglect or conduct conducing to her own matrimonial offence, was thereby estopped from giving evidence of her husband's conduct during the relevant period for the purpose of endeavouring to secure an order for maintenance appears to us to be misconceived. In reaching his conclusion in the Full Court Gavan Duffy J. referred to Lockyer v. Ferryman [2] and quoted from the speech of Cairns L.C. the following passage: "No man who shews that at the time of his first proceedings he had the whole facts within his knowledge, and who had the power to raise them - who puts upon his record statements which prove that he had the whole of this knowledge in his possession - can be heard, because he does not attempt to prove one part of the case, to say after the lapse of thirty years that he is entitled to commence a new litigation, to raise again a portion of the case which, if it had any foundation, was perfectly well known to him at the time of his first proceedings". But it should be observed that the appellant in that case was held to be estopped because in the second suit he attempted to reopen the very issue previously decided. In that case the appellant sought a declaration that he and a person then deceased and of whom the respondents were the executors had inter-married in Scotland many years before. But in a previous suit instituted some thirty years before the appellant had sought a declaration in the same terms. In this suit he had been unsuccessful, and it is clear that what he sought to establish in the second suit was that the marriage alleged in the first suit had taken place. In dealing with the question on appeal in the second suit Lord Cairns made it clear [3] that in stating the proposition, quoted above, he was not laying down any general rule "as to the extent to which a sentence in a declarator of marriage is binding as against any subsequent attempt that may be made to establish the marriage upon any new or different footing", and that he was content to dispose of the case in the manner indicated by him. But at no time was it suggested by his Lordship that if the issue in the second suit had been of a nature different from that in the first any question of estoppel would or could have arisen or that evidence relevant to the issues in the first suit would not have been admissible. Nor is the view which we have expressed inconsistent with the passage cited by Gavan Duffy J. from Hoysted v. Commissioner of Taxation [1] . To hold that the appellant's affidavit was admissible in the maintenance proceedings does not permit her to reopen "the same subject of litigation in respect of matters which might have been brought forward as part of the subject in contest".
