What happened
The proceedings began in the Family Court of Australia in August 1993 when Brigitte Maunz (the wife) sought property settlement orders under s 79 of the Family Law Act 1975 (Cth) against her former husband, Ernest Franz Allesch. By May 1995 the matter had been listed for final hearing but had not proceeded, partly because of steps taken by the husband. On 18 May 1995 a registry officer delivered a letter to the husband's home warning that if he did not appear at a directions hearing the following day the wife's application might be listed as undefended. The husband, then unrepresented and recently hospitalised with a myocardial infarct, did not appear. On 19 May 1995 Finn J ordered the matter listed for undefended hearing on 14 June 1995 and directed that the orders be served on him.
Those orders were served on 22 May 1995. When the undefended hearing occurred on 14 June 1995 the husband was in hospital in Sydney having undergone triple valve bypass surgery five days earlier. An affidavit of service recorded that the husband had told the process server he was “very sick” and had asked the server to leave. Finn J proceeded on the basis that she would allow a short period after service for the husband to apply to set any orders aside. On 10 July 1995 her Honour delivered reasons finding the net property pool to be $735,000 and awarding 55 per cent to the wife and 45 per cent to the husband. Formal orders were made on 10 August 1995. They required the husband to transfer his interest in two properties to the wife, pay her $87,513 plus costs, and take steps to enable the wife to receive her entitlement in a company. The orders were expressed to take effect seven days after service on the husband together with the reasons.
Service occurred on 17 August 1995. On 24 August 1995 the husband applied to set the orders aside. In his supporting affidavit he detailed his hospitalisation from 1 May 1995, lack of recollection of the May letter, admission to hospital on 3 June 1995, surgery on 5 June 1995, and ongoing recuperation. He also disputed the value and extent of the property pool and asserted reduced earning capacity. Finn J heard the application on 6 September 1995 and delivered judgment on 18 September 1995. Her Honour accepted the husband's evidence of serious illness and accepted that, if his foreshadowed financial evidence were accepted on a rehearing, the result might be substantially different. Nevertheless, she refused to set the orders aside. She weighed against reopening the wife's state of health (supported by medical evidence that the protracted proceedings were harming her mental health), the protracted nature of the litigation (commenced in 1993, listed for hearing in 1994 but delayed by the husband's actions and non-appearances), and her view that the husband could have taken the “relatively small step” of applying for an adjournment at some point between 1 May and 14 June 1995. She concluded that the interests of justice, including the wife's mental health and the public interest in finality, favoured dismissal.
The husband filed a notice of appeal on 4 October 1995. That appeal was dismissed as abandoned in May 1996 but reinstated in May 1998. It was heard by the Full Court on 24 September 1998 and dismissed on 26 November 1998. Kay and Brown JJ (with Lindenmayer J agreeing in the result) held that Finn J had erred in treating the proceedings as unusually protracted, in over-emphasising the ease of seeking an adjournment, and in giving undue weight to the wife's mental health evidence. They accepted that once a reasonable excuse is shown and a significantly different result may be achieved, the discretion to set aside is “severely narrowed”. However, they then exercised the discretion afresh as at the date of their decision. They pointed to the husband's unexplained delay in prosecuting the appeal, the fact that the orders had been substantially executed (the wife had obtained possession of the matrimonial home and both properties had been sold; a company property had been sold by consent and proceeds preserved), and the existence of costs orders in the wife's favour. They noted it was impossible to restore the parties to their pre-10 August 1995 positions and that a rehearing under s 79 by reference to then-current property and s 79(4) factors carried “no certainty” of a different result; they would be “speculating” as to the likely outcome. Lindenmayer J would have dismissed the appeal on the basis that no error by Finn J had been shown but agreed with the majority's alternative reasons.
The husband appealed to the High Court. No notice of contention was filed to support Finn J's orders on other grounds. The only issue was whether the Full Court had been correct to dismiss the appeal on the basis of delay, costs orders and the impossibility of perfect restitution. The High Court (Gaudron, McHugh, Gummow, Kirby and Hayne JJ) unanimously allowed the appeal, set aside the Full Court's orders and remitted the matter to the Full Court for further hearing and determination in accordance with the Court's reasons. Each party was ordered to bear their own costs in the High Court.
Why the court decided this way
The joint reasons of Gaudron, McHugh, Gummow and Hayne JJ and the separate reasons of Kirby J both rest on two interlocking propositions derived from the statute and from Taylor v Taylor (1979) 143 CLR 1. First, the appeal to the Full Court under ss 93A(2) and 94 is a rehearing, not an appeal in the strict sense nor a hearing de novo. The Full Court can receive further evidence, draw inferences, and may make the order that “ought to have been made in the first instance” or remit. Powers are exercisable only on demonstration of legal, factual or discretionary error, but once error is shown the appellate court may substitute its own view on the facts and law as they stand at the time of appeal. The joint reasons emphasise that this follows from the express power to receive further evidence, a power not possessed by courts confined to appeals in the strict sense.
Second, the discretion to set aside orders made in the absence of a party, now squarely within s 79A(1)(a) (“miscarriage of justice by reason of … any other circumstance”), is informed by the fundamental requirement that a person not be adversely affected by a judicial order without adequate opportunity to be heard. Both sets of reasons treat this as a corollary of natural justice. The joint reasons state that a court will “ordinarily” be satisfied of a miscarriage of justice if absence is adequately explained unless no different result would be reached on rehearing or a rehearing would work irremediable injustice. Injustice can often be cured by costs orders, but where orders have been carried into effect more limited relief may be necessary.
Applying these principles, the Court held that the Full Court had correctly identified error in Finn J's reasoning but had itself fallen into error. The majority in the Full Court had treated the husband's delay, the partial execution of orders and the costs orders as militating against setting aside, yet had not answered the anterior questions required by the statute and Taylor v Taylor: whether the husband's explanation was adequate (which it was), whether a different result might reasonably eventuate (Finn J had thought it might), and whether irremediable injustice would be occasioned to the wife. Moreover, by deciding to re-exercise the discretion by reference to circumstances as they existed in November 1998 rather than remitting, the Full Court was obliged to give the parties an opportunity to adduce evidence of those changed circumstances. The joint reasons note that the Full Court itself acknowledged it could “only be speculating” about the likely outcome of a fresh s 79 exercise; that speculation was impermissible without evidence. Kirby J expressed the point as two criteria: reasonable explanation for default, and an arguable case that a materially different result might follow. He held the Full Court had applied an overly stringent test of “certainty” rather than possibility, had taken account of post-order events without inviting updating evidence, and had therefore failed to perform its appellate function correctly.
Kirby J placed the analysis in the wider context of the audi alteram partem rule, tracing it from common-law maxims through international human rights instruments and constitutional implications. He stressed that while courts cannot force parties to appear, and must balance efficiency and the interests of the other party (including the wife's health), the principle remains that an adequately explained absence coupled with the possibility of a different outcome ordinarily requires a rehearing. Both reasons reject the notion that the protracted nature of the litigation or the wife's health concerns could, without more, preclude relief once the statutory test was met. The orders were therefore set aside and the matter remitted so that the Full Court could, on a correct legal footing and with appropriate procedural safeguards, decide whether to set aside the original orders and, if so, on what terms.
Before and after state of the law
Before Allesch v Maunz the law was shaped by Taylor v Taylor (1979) 143 CLR 1, which held that the Family Court possessed inherent power to set aside orders made in the absence of a party and that the discretion was to be exercised having regard to the right to be heard. The joint reasons in Taylor had treated the power as a corollary of natural justice; Murphy J had listed factors including explanation, delay, acquiescence and prejudice. Section 79A had been amended after Taylor to include the express ground of miscarriage of justice “by reason of … any other circumstance”, but uncertainty remained whether the statutory power or inherent power governed, and how the discretion should interact with appellate rehearing principles.
The decision in CDJ v VAJ (1998) 197 CLR 172 had clarified that appeals under s 94 are rehearings in which further evidence may be received and the appellate court may decide on the law and facts as they then stand. Allesch v Maunz builds directly on both authorities. It confirms that s 79A(1)(a) now subsumes the situation of orders made in absence and that the statutory test of miscarriage of justice is to be applied in the same manner as the inherent power. The “ordinary” rule is now authoritatively stated: adequate explanation plus possibility of different outcome equals miscarriage unless irremediable injustice is shown. The judgment also adds a procedural safeguard for rehearing appeals from discretionary judgments: if the appellate court chooses to re-exercise by reference to current circumstances rather than remit, it must allow the parties to lead evidence on those circumstances. Failure to do so is itself error.
After the decision, the law is clearer in three respects. First, the source of power is statutory; inherent power is of doubtful continuing scope. Second, the threshold for miscarriage is not a balancing exercise in which the wife's health or the length of proceedings can automatically prevail once explanation and possible different outcome are established; those factors go only to whether injustice is irremediable. Third, appellate courts exercising rehearing powers in family property matters must be astute to procedural fairness when they depart from the facts as found at first instance. The disposition by remission rather than final determination on the existing record underscores that where circumstances have changed, the proper course is often to remit so that a single judge can apply s 79(4) to the property as it then exists.
Key passages with plain-English translation
The joint reasons contain several passages that have become canonical. At the heart is the statement that “a court will, ordinarily, be satisfied that there has been a miscarriage of justice if a person has suffered an adverse order in circumstances where his or her failure to appear is adequately explained unless it also appears that no different result would be reached on a rehearing or that a rehearing would work an irremediable injustice to the other side.” In plain English this means: if you had a good reason for missing court and the judge might have reached a different answer had you been there, the order should usually be wiped so you can have your say—unless letting you back in would cause the other side harm that money or costs orders cannot fix.
Kirby J's exposition of the audi alteram partem principle is equally important: “It is a principle of justice that a decision-maker, at least one exercising public power, must ordinarily afford a person whose interests may be adversely affected by a decision an opportunity to present material information and submissions relevant to such a decision before it is made.” Translation: before a court can make an order that hurts you, it must give you a fair chance to put your side of the story. The Court makes clear this is not an absolute right to force an adjournment forever, but a strong presumption that applies with particular force when illness is the reason for absence.
On the appellate function the joint reasons state: “If on an appeal by way of rehearing from a discretionary judgment an appellate court is minded to exercise the discretion in question by reference to circumstances as they exist at the time of the appeal, it is necessary that the parties be given an opportunity to adduce evidence as to those circumstances.” Plain English: if the appeal judges decide to judge the case on today's facts rather than the facts as they were when the trial judge decided, they must let both sides bring fresh evidence about what has changed. The Full Court did not do this; it speculated instead. Kirby J adds that it is wrong to demand “certainty” of a different outcome; the applicant need only show that a materially different result “might arguably follow”.
These passages translate the abstract concepts of natural justice and rehearing into concrete, workable rules for family law practitioners. They emphasise that procedural fairness is not a technicality but the foundation on which the discretion under s 79A rests.
What fact patterns trigger this precedent
This precedent is triggered whenever a party to Family Court property proceedings under s 79 is absent from a hearing that produces an adverse order, that absence is adequately explained (classically by serious illness, hospitalisation or other unavoidable cause), and the absent party can point to material that might reasonably produce a different division of property. The explanation must be reasonable having regard to the interests of the other party and the public interest in finality; a bare assertion of illness without corroboration or prompt action will not suffice. The possibility of a different result need not be certain; it is enough that the court can see that the absent party's evidence, if accepted, “may well” alter the outcome.
The precedent applies with added force where the orders have been only partially executed and where terms can be fashioned to protect the other party (for example, costs orders or preservation of sale proceeds). It does not apply where the absence is deliberate, unexplained, or where the party has acquiesced for a lengthy period. Nor does it apply if a rehearing would occasion irremediable prejudice that cannot be cured on terms. The judgment expressly contemplates that changed circumstances between the original hearing and the appeal may make remission the preferable course so that s 79 can be applied to the property “as exists as at the date of that retrial”.
Fact patterns outside family law but involving statutory powers to set aside orders on the ground of miscarriage of justice or analogous inherent powers will also engage the underlying principle that justice requires an opportunity to be heard. The decision is not limited to unrepresented litigants; it applies equally to represented parties whose lawyers have failed to appear through no fault of the client.
How later courts have treated it
Although the judgment itself does not cite subsequent authority, its reasoning expressly builds upon and refines Taylor v Taylor and CDJ v VAJ. The joint reasons treat the statements in Taylor about the right to be heard as authoritative and extend them to the construction of the amended s 79A(1)(a). The emphasis on the need to afford parties an opportunity to lead updating evidence when an appellate court re-exercises discretion by reference to current facts is presented as a necessary implication of the rehearing nature of the appeal as explained in CDJ v VAJ. Kirby J's separate reasons reinforce the point by reference to the same authorities and to the broader constitutional and human-rights context also discussed in those cases.
The judgment has therefore been treated as settling the interaction between the statutory miscarriage-of-justice power and the appellate rehearing function. It stands as the leading modern statement of the “ordinary” rule for setting aside ex parte orders in family property matters. Courts applying it have been directed to ask first whether the explanation is adequate and whether a different result is arguable, and only then to consider prejudice to the other party and whether that prejudice is remediable. The procedural safeguard requiring an opportunity to lead further evidence on changed circumstances has become a standard requirement in appeals where the appellate court proposes to depart from the factual basis upon which the primary judge exercised discretion. The disposition by way of remission rather than final determination underscores that the Full Court should not speculate but should ensure it has an evidentiary foundation before deciding that no different result is possible.
Still-open questions
The judgment leaves several questions for future decision. First, the precise scope of any residual inherent power after the broadening of s 79A(1)(a) is left open; the joint reasons doubt whether there remains any need for it, but do not foreclose argument in a suitable case. Second, the content of “irremediable injustice” is not exhaustively defined. The reasons accept that injustice may often be cured by costs or by limiting the rehearing to particular issues, but give no closed list of circumstances in which prejudice will be regarded as irremediable once orders have been executed and third-party rights have intervened.
Third, the standard of appellate review when a Full Court has itself re-exercised the s 79A discretion remains to be fully worked out. The present case turned on clear legal error (application of a “certainty” test and failure to invite updating evidence), but the boundary between permissible appellate evaluation of prejudice and impermissible speculation is not sharply drawn. Fourth, the weight to be given to a party's mental health or the public interest in finality when balanced against an adequately explained absence is left to the facts of each case; the judgment rejects giving those factors decisive weight on the facts before it but does not prescribe a hierarchy.
Finally, the interaction with enforcement proceedings that have progressed in the interim is not fully resolved. The reasons note that the proceeds of sale had been preserved pending the appeal, but leave open what terms should be imposed when assets have been dissipated or third parties have acquired interests. These open questions ensure that Allesch v Maunz remains a starting point rather than the final word in any complex case involving delayed applications to set aside ex parte property orders.
