Federal Court of Australia makes first aggregate damages award in a funded representative proceeding in Toyota Class Action

Federal Court of Australia makes first aggregate damages award in a funded representative proceeding in Toyota Class Action

The following piece was contributed by Martin del Gallego and Matthew Harris of Australian law firm, Piper Alderman. This article considers a recent decision of the Federal Court of Australia, awarding damages to class action claimants on an aggregate basis.  Aggregate damages is a rare global award which covers all group members described or identified in the award.  This was the first instance of aggregate damages being awarded to a funded litigant in Australia, and may spur a trend in representative claims brought on this basis. In Williams v Toyota Motor Corporation Australia Limited (Initial Trial) [2022] FCA 344, Justice Michael Lee relied on s 33Z(1)(e) of the Federal Court of Australia Act 1976 (Cth) (the Act) to award damages to group members in possession of certain Toyota vehicles throughout the entirety of the claim period, calculated as the percentage reduction in value of their vehicle or vehicles.  It has been estimated that Toyota’s total aggregate damages bill may exceed AU$2 billion. Key Takeaways
  • For an order of aggregate damages to be made in a representative proceeding, the Court needs to be satisfied on a principled basis with which to assess and distribute the relief;
  • The analysis must be informed by general principles governing the assessment of damages, and can result in an award of aggregated damages applying to a specific class of group members within a representative proceeding;
  • While the judgment is liable to spur a trend in claims for aggregate damages, precisely how such an award will impact the approval of legal costs and a funder’s commission remains to be seen.
Background to the proceedings The case before the Court concerned claims relating to Toyota’s supply of 264,170 defective diesel vehicles to Australian consumers between 1 October 2015 and 23 April 2020 (Relevant Period).  These vehicles were fitted with diesel combustion engines and a ‘diesel exhaust after treatment system’, or ‘DPF’, aimed at reducing harmful pollutants and other emissions from the engine.  The case alleged that the vehicles were defective because the DPF was not designed to function during all reasonable driving conditions, and even if driven normally, there was a propensity for the car’s exhaust to emit excessive white smoke and malodour, and cause reduced fuel efficiency and trigger ‘excessive’ notifications prompting the need for service or repair. In alleging that the vehicles were not of ‘acceptable quality’ in breach of the statutory guarantee under s 54 of the Australian Consumer Law (ACL), and that Toyota’s conduct had been misleading and deceptive in contravention of ss 18, 29(1)(a) and (g), and 33 of the ACL, the lead applicant sought two types of damages under s 272 of the ACL:
  • Under s 272(1)(a), damages for the reduction in value of each relevant vehicle resulting from the failure to comply with s 54 of the ACL; and
  • Under 272(1)(b), other reasonably foreseeable loss or damage incurred as a result of the defect and failure to comply with s 54 of the ACL, including excess taxes, fuel consumption, financing costs, servicing costs and lost income.
Of these heads of damage, only two were suitable for determination at the initial trial of the lead applicant’s claim:  the ‘reduction in value’ damages under s 272(1)(a) and damages for excess GST paid by group members in connection with acquiring the relevant vehicles under s 272(1)(b).  (A separate question had been asked and answered in an earlier interlocutory application in the case, clearing the way for a potential aggregate damages award, in respect of only part of the lead applicant and group members’ claims.[1]) Aggregate Damages Having found in favour of the lead applicant, on among other things, their ‘acceptable quality’ cases, Justice Lee also found that the same determinations could be made on a common basis for the remainder of group members.  His Honour found that the lead applicant and group members were entitled to damages for the reduction in value of their vehicles, and for excess GST paid in connection with that reduction.  Accordingly, it was necessary for his Honour to determine a principled basis for arriving at a quantum of the reduced value which could be applied on an aggregate basis to all relevant group members. The Federal Court’s power to award damages on an aggregate basis is found in s 33Z of the Act. This section provides, among other things, that the Court may, in determining a matter in a representative proceeding, make an award of damages for group members, sub‑group members or individual group members, being damages consisting of specified amounts or amounts worked out in such manner as the Court specifies,[2] or award damages in an aggregate amount without specifying amounts awarded in respect of individual group members.[3]  Further, subject to section 33V of the Act, the Court is not to make an award of damages under s 33Z(1)(f) unless a reasonably accurate assessment can be made of the total amount to which group members will be entitled under the judgment.[4] Noting that class actions were not the ‘Galapagos islands’ of litigation, Justice Lee observed that an award of damages, even on an aggregate basis, was subject to two overarching principles as to the award of compensatory damages.[5]  His Honour observed that an award of compensatory damages must be considered in the light of the overriding compensatory principle, and that even where the process of estimating damages is difficult, the Court ‘must do what it can’, this principle equally applying to an assessment of ‘reduction in value’ damages. Justice Lee found that the Court is not permitted, by s 33Z of the Act, to take an approach of awarding aggregate damages on a per vehicle basis and determining the separate question of distribution at a later stage. Because of this, his Honour was faced with a challenge of how to distribute relief to group members who had possessed the relevant vehicles for only part of the Relevant Period.  His Honour termed these group members as ‘Partial Period Group Members’ and concluded at [432]: The bottom line is that without knowing the price at which, or the time at which, the Partial Period Group Members bought and sold Relevant Vehicles on the secondary market, one cannot determine on a principled basis how the compensation for the owners of those Relevant Vehicles ought to be assessed or distributed. One must always bear in mind the whole object of any award of damages is to put the claimant in the position the claimant would have been in but for the contravening conduct. Ultimately, the Partial Period Group Members will be required to undertake an individualised assessment of their loss. For the ‘Entire Period Group Members’, that is, people who possessed the relevant vehicles throughout the entirety of the Relevant Period, the Court awarded aggregate damages under s 33Z(1)(e) of the Act.  The award of aggregate damages for the Entire Period Group Members was calculated on the basis of a 17.5% reduction in value of the average retail price of the particular type of vehicle at the particular time it was purchased.  In circumstances where the group member paid a price lower than the average retail price for their vehicle, the lower of the two prices was said to be the applicable comparator from which the 17.5% reduction in value is to be calculated.[6]  In being satisfied there was a reduction in value of the relevant vehicles of 17.5% resulting from the failure to comply with s 54 of the ACL, Lee J also found that Entire Period Group Members were also entitled to recover the excess GST they paid on that reduction in value, calculated as 10% of the reduction in value.[7] Regarding the claim for damages under s 33Z(1)(f) of the Act, the Court declined to award aggregate damages on this basis, because his Honour was not satisfied that a reasonably accurate estimate could be made of the total amount owing to group members as required by s 33Z(3). Conclusion Williams is the first instance of a Court awarding aggregate damages in a funded representative proceeding, and provides helpful guidance on how the Court will approach such claims, particularly where only part of the claim is suitable for determination on an aggregate basis.  That said, while Justice Lee found in favour of the class on the issue, it is plain that such an assessment will need to be carried out on a case-by-case basis.

UK Supreme Court Upholds Key Class Action Win for Funders in Apple Case

By John Freund |

The UK Supreme Court has declined to hear Apple’s appeal in Apple Inc and others v Gutmann, leaving intact a Court of Appeal decision that significantly strengthens the position of litigation funders in collective proceedings before the Competition Appeal Tribunal (CAT).

An article in Law Gazette reports that the Supreme Court refused Apple’s petition on the grounds that it did not raise an arguable point of law, effectively endorsing the lower court’s April 2025 decision. That ruling affirmed that litigation funders can be paid directly from damages recovered in a class action before distributions are made to class members. The decision resolved longstanding ambiguity surrounding Sections 47C(3) and (6) of the Competition Act 1998 and Rule 93 of the CAT Rules 2015.

The Court of Appeal held that the CAT has wide discretionary authority to order payments to class representatives for costs, fees, and disbursements, provided such allocations are deemed fair and reasonable under the tribunal’s supervisory jurisdiction. This was a pivotal victory for claimant-side funders, who have long warned that being last in line for recovery—after damages are disbursed—posed unacceptable risk in UK opt-out cases.

Law firm Charles Lyndon, counsel for class representative Justin Gutmann, welcomed the Supreme Court’s decision not to revisit the matter, stating that it brings “welcome certainty” to the evolving collective proceedings regime and affirms the CAT’s broad discretion in addressing complex, end-of-case allocation scenarios.

This decision is expected to have a profound impact on the UK’s competition class action landscape. Funders now have greater confidence in the recoverability of their investments, potentially spurring more funding activity in CAT proceedings. The ruling may also prompt defendants to reconsider their settlement calculus, knowing that funders now enjoy a more secure repayment pathway.

Elite Colleges Challenge Lawyers’ Litigation Funding in Major Antitrust Case

By John Freund |

Elite U.S. universities embroiled in a high-stakes antitrust class action are now targeting the use of third‑party litigation funding by plaintiffs’ counsel in a bid to derail class certification. At issue is whether a lead firm’s reliance on external financing renders it “inadequate” under class action rules — a novel approach that raises fresh procedural and policy questions.

An article in Reuters notes the the suit alleges that Cornell, Penn, MIT, Georgetown, Notre Dame and others favored wealthy applicants over students needing financial aid, plaintiffs’ counsel (led by Gilbert Litigators & Counselors, or GLC) is facing attacks over transparency and risk allocation. The universities contend that GLC mischaracterized its financial exposure by not fully disclosing its funding arrangements. GLC responds that it only uses outside funding for a portion of its fees (covering 40% of its own, and under 16% of the aggregate) and that no court has previously held that use of funding makes class counsel inadequate. A judge has already found the funding documents “potentially relevant” to the certification motion, underscoring the stakes.

Legal commentators call this a new twist in class litigation — rather than questioning the merits or fairness of funding, defendants are now probing its procedural footprint. The case also dovetails with a broader trend: litigation funders are becoming more visible and controversial, particularly when their support is used by class‑action counsel. Reuters Meanwhile, in adjacent news, law firms are consolidating and AI‑driven tools for plaintiffs’ practices are attracting investor capital — further reshaping the economics of litigation.

This challenge could force courts nationwide to reinterpret adequacy standards in class actions, potentially chilling the use of external funding. It may also provoke funders, defense firms, and plaintiffs to recalibrate disclosure rules and risk-sharing norms across major litigation.

Siltstone vs. Walia Dispute Moves to Arbitration

By John Freund |

Siltstone Capital and its former general counsel, Manmeet (“Mani”) Walia, have agreed to resolve their dispute via arbitration rather than through the Texas state court system—a move that transforms a high‑stakes conflict over trade secrets, opportunity diversion, and fund flow into a more opaque, confidential proceeding.

An article in Law360 notes that Siltstone had accused Walia of misusing proprietary information, diverting deal opportunities to his new venture, and broadly leveraging confidential data to compete unfairly. Walia, in turn, has denied wrongdoing and contended that Siltstone had consented—or even encouraged—his departure and new venture, pointing to a release executed upon his exit and a waiver of non‑compete obligations.

The agreement to arbitrate was reported on October 7, 2025. From a governance lens, this shift signals a preference for dispute resolution that may better preserve business continuity during fundraising cycles, especially in sectors like litigation finance where timing, investor confidence, and deal pipelines are critical.

However, arbitration also concentrates pressure into narrower scopes: document production, expert analyses (especially of trade secret scope, lost opportunity causation, and valuation), and the arbitrators’ evaluation. One point to watch is whether interim relief—protecting data, limiting competitive conduct, or preserving the status quo—will emerge in the arbitration or via court‑ordered relief prior to final proceedings.
