No Fairness, No Finality: Appeal Succeeds After Wife Denied Procedural Fairness

In Cuyper & Cuyper [2025] FedCFamC1A 176, Justice Riethmuller of the Federal Circuit and Family Court (Division 1, Appellate Jurisdiction) allowed a wife’s appeal from a Western Australian Magistrates Court decision concerning final property orders. The appeal turned on the denial of procedural fairness — where the husband changed the property division sought on the morning of trial without proper notice — and on significant factual and legal errors in assessing contributions. The Court held that the wife had not been given a fair opportunity to respond to a last-minute shift from a 50/50 to a 60/40 division, and that the trial magistrate erred in both fact and method by assuming equality of contributions as a starting point. The case reinforces the importance of procedural fairness, accurate factual findings, and adherence to proper methodology under Stanford v Stanford and Mallett v Mallett.

Facts

  • The parties married in 2006 and separated in 2021 after a 15-year marriage with two children.
  • The husband, a FIFO worker, owned the Suburb B property prior to the marriage.
  • The wife was primarily a homemaker and caregiver since 2007.
  • Following separation, the wife left the home but later reoccupied it before moving interstate.
  • The husband initiated property proceedings in January 2024.
  • The wife later disengaged from proceedings, citing mental health and safety concerns.
  • At final hearing, the husband’s lawyer changed the proposed division from 50/50 to 60/40 in his favour on the morning of trial; the wife was absent and unrepresented.
  • The magistrate proceeded, awarding the wife 45% of the total asset pool, equating to roughly $58,000 less than what was earlier proposed.

Issues on Appeal

  1. Was the wife denied procedural fairness when the respondent changed the orders sought at trial without adequate notice?
  2. Did the magistrate commit an error of fact in miscalculating the husband’s initial contribution?
  3. Did the magistrate err in law by adopting an “adjustment” approach implying equal starting contributions?
  4. Were the findings on contributions and adjustments under s 79(2) of the Family Law Act 1975 sustainable?
  5. Should the appeal court re-exercise discretion or remit the matter for rehearing?

Law

The Court applied the following principles:

  • Procedural fairness (natural justice) — parties must have real opportunity to know and respond to the case made against them (Allesch v Maunz (2000) 203 CLR 172).
  • Family Law Act 1975 (Cth):
  • s 79(2) – Court must make orders that are just and equitable.
  • s 75(2) – Future needs adjustments.
  • s 102NA – Restrictions on personal cross-examination in family violence cases.
  • Leading authorities:
  • Stanford v Stanford (2012) 247 CLR 108 – threshold question of justice and equity.
  • Mallett v Mallett (1984) 156 CLR 605 – no presumption of equal contributions.
  • Dickons & Dickons (2012) 50 Fam LR 244 – holistic assessment of contributions.
  • Preston & Preston (2022) 66 Fam LR 285 – appellate restatement rejecting “starting point of equality.”
  • Dumont & Cabrara [2025] FedCFamC1A 82 – error of law where a court applies an “adjustment” model implying equality.

Application of Law to Facts

1. Procedural Fairness

  • The husband’s application had consistently sought a 50/50 division, but on the morning of trial, he sought 60/40 in his favour.
  • The wife was not present and was only emailed the new proposed orders at 9:12am that day ([24]–[27]).
  • The Court held this provided insufficient notice to an unrepresented party.
  • Justice Riethmuller found that “notice to the unrepresented appellant on the day of the final hearing was not sufficient to reasonably put her on notice of the orders then sought … [she] was not afforded procedural fairness by such late notice” ([27]).
  • Procedural fairness required meaningful notice of any substantive change in outcome sought — particularly where the opposing party is self-represented.
  • Held: Procedural fairness denied → miscarriage of justice established.

2. Error of Fact — Husband’s Initial Contributions

  • The magistrate found the husband entered the relationship with $200,000 equity, but evidence showed it was only $15,000–$20,000 ([43]).
  • This was a material error in a modest asset pool (~$1.16 million).
  • The appellate judge found this “significant error of fact” infected the contribution findings ([43]–[45]).

3. Error in Legal Approach to Contributions

  • The magistrate’s phrase “an adjustment of 10% in the applicant’s favour” implied a starting point of equality, contrary to Mallett v Mallett and Preston & Preston.
  • Justice Riethmuller held this reflected an incorrect heuristic of equal starting contributions, inconsistent with law ([46]–[48]).
  • Held: Legal error established — contributions must be assessed holistically, not by mathematical adjustment from equality.

4. Just and Equitable Requirement

  • Although the magistrate cited Stanford v Stanford and found making orders was just and equitable ([38]), the underlying contribution findings were tainted by error, rendering the overall outcome unsafe.

5. Relief

  • The appeal was allowed in part.
  • Orders 2(e)–(g) and 3–14 (distribution of proceeds) were set aside.
  • Proceeds of sale to be held in trust pending further order.
  • Matter remitted for rehearing due to incomplete evidence and procedural unfairness.
  • Respondent granted a costs certificate under s 6 of the Federal Proceedings (Costs) Act 1981 (Cth).

Judgment and Reasoning

Justice Riethmuller held:

“Procedural fairness requires that a person be provided with a real opportunity to be heard. For the opportunity to be heard to be real, it is necessary that the person have reasonable notice of … the substance of the orders sought.” ([27])

He further found:

  • “Notice … on the day of the final hearing was not sufficient to reasonably put the appellant on notice.” ([27])
  • The trial magistrate’s reliance on an “adjustment” approach improperly assumed equality of contributions, contrary to established doctrine ([46]–[48]).
  • These errors, combined with the factual misstatement of the husband’s equity, justified setting aside the orders ([43], [49], [55]).

Key Precedents Cited

  • Allesch v Maunz (2000) 203 CLR 172 – appeal rehearing standard ([58]).
  • Stanford v Stanford (2012) 247 CLR 108 – “just and equitable” threshold ([38]).
  • Preston & Preston (2022) 66 Fam LR 285 – incorrect “adjustment” model ([47]).
  • Dumont & Cabrara [2025] FedCFamC1A 82 – reinforces the same principle ([47]–[48]).
  • Dickons & Dickons (2012) 50 Fam LR 244 – holistic approach ([48]).

Take-Home Lesson

“Procedural fairness is the foundation of justice — even a 5% change can make a world of difference.”

This decision underscores that:

  • Courts must not proceed on last-minute changes to relief sought without fair notice, especially when a party is self-represented.
  • Judicial officers must avoid “starting-point equality” shortcuts in contribution assessments.
  • Even modest factual errors can amount to appealable error when they materially affect the outcome.
  • The Cuyper appeal reiterates that fairness and accuracy outweigh speed or convenience in family property litigation.
