The principles to be applied
13 The circumstances in which a Court may "go behind" a judgment relied upon in bankruptcy proceedings have been well canvassed. The seminal decisions include Corney v Brien (1951) 84 CLR 343 and Wren v Mahoney (1972) 126 CLR 212. Many decisions have since applied these authorities and earlier English decisions.
14 One such decision of this Court is Ahern v Deputy Commissioner of Taxation (QLD) (1987) 76 ALR 137 ("Ahern"). Davies, Lockhart and Neaves JJ there stated the position to be as follows:
It is well established that a court exercising bankruptcy jurisdiction has undoubted discretion to go behind a judgment, particularly one obtained by default or compromise or where fraud or collusion is involved and inquire whether the judgment is founded on a real debt: Corney v Brien (1951) 84 CLR 343. Where the judgment is by default the court will go behind the judgment if there is a bona fide allegation that no real debt underlies the judgment: Corney v Brien. Even where the judgment was obtained following a hearing on the merits where both parties appeared, if there are substantial reasons for questioning whether behind the judgment there is in truth and reality a debt due to the petitioning creditor, the court will go behind the judgment and inquire into the consideration for it: Wren v Mahony (1972) 126 CLR 212 per Barwick CJ, with whose reasons Windeyer and Owen JJ agreed; Menzies and Walsh JJ dissenting. Barwick CJ said (at 224):
The judgment is never conclusive in bankruptcy. It does not always represent itself as the relevant debt of the petitioning creditor, even though under the general law, the prior existing debt has merged in a judgment. But the bankruptcy court may accept the judgment as satisfactory proof of the petitioning creditor's debt. In that sense that court has a discretion. It may or may not so accept the judgment. But it has been made quite clear by the decisions of the past that where reason is shown for questioning whether behind the judgment or as it is said, as the consideration for it, there was in truth and reality a debt due to the petitioning creditor, the court of bankruptcy can no longer accept the judgment as such satisfactory proof. It must then exercise its power, or if you will, its discretion to look at what is behind the judgment: to what is its consideration.
It is also well established that in general a court exercising jurisdiction in bankruptcy should not proceed to sequestrate the estate of a debtor where an appeal is pending against the judgment relied on as the foundation of the bankruptcy proceedings provided that the appeal is based on genuine and arguable grounds …
These cases rest on the broad principle that before a person can be made bankrupt the court must be satisfied that the debt on which the petitioning creditor relies is due by the debtor and that if any genuine dispute exists as to the liability of the debtor to the petitioning creditor it ought to be investigated before he is made bankrupt. Bankruptcy is not mere inter partes litigation. It involves change of status and has quasi-penal consequences: (1987) 76 ALR 137 at 147 to 148.
In the present case, particular emphasis was sought to be placed by Senior Counsel for Mr Compton upon the observations of Barwick CJ in Wren v Mahoney (1972) 126 CLR at 224. See also: Re Hughes; Ex parte Geo M Hume Pty Ltd [1997] FCA 680 per Merkel J.
15 Reference should also be made to the decision of Hely J in Commonwealth Bank of Australia v Jeans [2005] FCA 978. The debtor had there unsuccessfully sought to withdraw an admission that he had duly executed a guarantee. In rejecting a submission that there had not been a "fully contested hearing" such that the Court should "go behind" the judgment, his Honour concluded:
[17] The debtor, on the other hand, contends that there has not been a fully contested hearing on the merits because the debtor was precluded from raising as an issue in the proceedings his contention that he did not sign the guarantee (on p 12) as guarantor. It is submitted that, upon this aspect, the case is analogous to a default judgment, and substantial reasons have been given for questioning whether there really was a debt due to the petitioning creditor.
[18] In my view, the circumstances of this case are far removed from a case in which a judgment is entered by default. There was a fully contested hearing … on the issue of the debtor's liability under the guarantee, after the debtor had a reasonable opportunity to raise whatever grounds he wished to rely upon to resist the Bank's case based upon the guarantee. As is always the case, the scope of the contest was determined by the respective cases put forward by the parties, who are ordinarily bound by the way in which they have chosen to conduct the proceedings.
…
[20] … The debtor's submission that he was prevented 'for procedural reasons' from raising the issue of non-execution is not a fair reflection of why the debtor was not permitted to raise that issue.
[21] In my view, the fact that the debtor was shut out from raising the defence on which he now seeks to rely because the proper administration of justice so required provides an insufficient foundation for this Court to go behind a judgment regularly obtained. I acknowledge that in Wren v Mahoney Barwick CJ said (at 224) that whether the Court of Bankruptcy will consider 'whether there is a satisfactory proof of the petitioning creditor's debt' is not a mere matter of its own discretion. Indeed, the circumstances may be such that the Court must exercise its power to look at what is behind the judgment. However, for the reasons which I have given, this is not such a case.
[22] Therefore, I decline to exercise my discretion to go behind the judgment on which the petition is based, and I determine the preliminary question accordingly …

16 The earlier decisions have also been more recently reviewed by Wigney J in Katter v Melhem (No 2) [2014] FCA 1176, (2014) 319 ALR 646. His Honour there helpfully summarised the principles to be applied as follows:
Relevant principles - "Going behind" a judgment
[69] The existence of a judgment is prima facie evidence of a debt: Corney v Brien (1951) 84 CLR 343 at 355; [1951] ALR 525 (Corney v Brien) per Fullagar J. However, a judgment is never conclusive in bankruptcy and the court has a discretion to "go behind" the judgment to investigate whether there was a good debt to support it: Corney v Brien at CLR 347 per Dixon, Williams, Webb, Kitto JJ, at 353-4 per Fullagar J.
[70] The court will not, however, inquire into the consideration for a judgment as a matter of course: Wren v Mahoney (1972) 126 CLR 212 at 222-3; [1972] ALR 307 per Barwick CJ. Whilst the circumstances in which the court will inquire into the validity of a judgment debt are not closed … and there is no inflexible rule … it is possible to identify a number of guiding principles.
[71] First, the court looks with suspicion on consent judgments and default judgments … Where the judgment in question is a default judgment, it appears that the court will always "go behind" the judgment if there is what it regards as a bona fide allegation that no real debt lay behind the judgment: Corney v Brien at 357-8 per Fullagar J.
[72] Second, if the judgment in question followed a full investigation at a trial at which both parties appeared, the court will not reopen the matter unless a prima facie case of fraud or collusion or miscarriage of justice is made out: Corney v Brien at 356-7 per Fullagar J. In Re Flatau; Ex parte Scotch Whisky Distillers Ltd (1888) 22 QBD 83 at 86, Fry LJ said: "this power has never, so far as I am aware, been extended to cases in which a judgment has been obtained after issues have been tried out before a [c]ourt". In Corney v Brien, Fullagar J said (Corney v Brien at 358) that he had not been able to find any such case since Fry LJ made this statement in 1888.
[73] Third, where judgment has been entered in pursuance of a compromise, grounds must be shown for challenging the compromise before the subject matter of the judgment will be reopened: Corney v Brien at 357 per Fullagar J. That is because it is the compromise and not the claim that was compromised that is the foundation of the judgment …
…
[77] Fourth, the court should not go behind a judgment where the grounds upon which the judgment is challenged are such that, if accepted, they would only support a finding that the amount of the debt be reduced and would not support a finding that there was, in truth, no debt at all …
[78] The particular circumstances of any given case may no doubt throw up other considerations relevant to whether the court should exercise its discretion to go behind a judgment. Where the judgment debtor seeks to go behind the judgment on particular grounds, it is difficult to see why it would not be a relevant consideration that those grounds could have been, but were not, raised in opposition to the judgment, or in an application to set aside the judgment. Parties are ordinarily bound by the way they have chosen to conduct litigation. The fact that, for whatever reason, a party did not put particular arguments before the court that made (or refused to set aside) the judgment does not mean that there was no relevant hearing on the merits …
[79] The question whether the judgment is to be reopened or "gone behind" at all will usually involve some preliminary investigation of the merits of the attack of the judgment: Corney v Brien at 358. That question can and often is dealt with as a preliminary question … Once the court decides that it will go behind the judgment "the whole [of the] matter is open": Corney v Brien at 358. Where it is legitimate to go behind a judgment entered after trial, there would effectively be no alternative but to retry the whole case.
