Full Federal Court: Plus500 Unfair Arbitration Clause Voided

• The Full Federal Court dismissed appeals by Plus500AU and Plus500 Limited, upholding a ruling that an arbitration clause in their user agreement was an unfair contract term.
• The court found the clause void because it failed to clearly inform customers that arbitration would block court or class action access, and its cost made it impractical for typical claims.
• The customer initiated a class action after losing $111,948 on the Plus500AU trading platform, alleging misleading and unconscionable conduct.
• The Full Court agreed the clause created a significant imbalance, disproportionately affecting customers and not being reasonably necessary for Plus500AU's interests.
• This decision affirms the importance of fair and transparent dispute resolution clauses in consumer contracts, especially in financial services.

The court determined that the arbitration clause created a significant imbalance, effectively preventing customers from pursuing judicial remedies or participating in class actions.

The Full Federal Court has rejected an attempt by Plus500AU Pty Ltd and its parent company, Plus500 Limited, to compel a customer class action into arbitration. In a significant ruling delivered on September 16, 2026, under the case name Plus500AU Pty Ltd v AghaeiRad [2026] FCAFC 125, the court upheld an earlier decision that an arbitration clause within the company's user agreement constituted an unfair contract term, rendering it void. This outcome means the class action, initiated by a customer who lost a substantial sum trading on the platform, can proceed in the Federal Court.

The dispute originated after a customer opened a trading account with Plus500AU in August 2020. By June 2021, this individual had deposited and subsequently lost $111,948. Despite indicating acknowledgement of Plus500AU's user agreement by checking a box, the customer had not actually reviewed the document. The agreement, specifically clause 23, outlined a multi-stage dispute resolution process culminating in arbitration, though it also noted the availability of the Australian Financial Complaints Authority (AFCA) for customers. The customer later launched a class action under Part IVA of the Federal Court of Australia Act 1976 (Cth), alleging various breaches including misleading conduct, unconscionable conduct, and contract violations related to the platform's operation.

Plus500AU and Plus500 Limited subsequently sought to halt the class action and refer the matter to arbitration, citing section 8(1) of the Commercial Arbitration Act 2010 (NSW). However, the primary judge determined that the arbitration clause was an unfair contract term under section 12BF of the Australian Securities and Investments Commission Act 2001 (Cth) and declared it void. This initial finding set the stage for the Full Federal Court's review.

The primary judge's decision to void the arbitration clause was based on several key findings regarding its unfairness. Crucially, the clause failed to explicitly inform customers that engaging in arbitration would preclude them from pursuing legal action in court or participating in a class action. Furthermore, the court observed that arbitration was largely theoretical for most customers, as its associated costs typically outweighed the value of their individual claims, making it an impractical avenue for redress. Plus500AU also did not demonstrate that the clause was reasonably necessary to safeguard its legitimate business interests.

Evidence presented during the proceedings underscored the practical implications of the clause. Between September 2017 and March 2021, Plus500AU received 566 complaints, with 289 of these being escalated to AFCA. Notably, not a single one of these complaints ultimately proceeded to arbitration, reinforcing the court's view that the mechanism was largely ineffective for customers. The Full Federal Court, upon review, found no error in the primary judge's reasoning, affirming that the clause indeed created a significant imbalance in the rights and obligations of the parties.

The Full Federal Court concurred with the assessment that the arbitration clause disproportionately favored Plus500AU, effectively preventing customers from initiating lawsuits or joining class actions. The court noted that while the clause heavily impacted customers, Plus500AU itself would rarely find it necessary to sue an individual customer, as the primary judge had observed. The finding that the clause constituted an unfair contract term was, by itself, sufficient grounds for the Full Court to dismiss both appeals lodged by Plus500AU and Plus500 Limited.

Significantly, the court did not need to determine whether enforcing the clause would also amount to unconscionable conduct, as the unfair contract term finding was conclusive. Beyond the arbitration issue, the Full Court also independently concluded that the relief sought by Plus500AU was inconsistent with the court's responsibility to protect absent group members in a class action. It was noted that group members would have no opportunity to seek substitution or receive notice if the class action were to be entirely halted. Ultimately, both appeals were dismissed, and Plus500AU and Plus500 Limited were ordered to cover the costs incurred during the appeals process.

This ruling serves as a critical reminder for businesses, particularly those operating in financial services, about the enforceability of arbitration clauses within standard form consumer contracts. The decision underscores that such clauses must be transparent and genuinely fair, especially when they could restrict customers' access to judicial remedies or participation in collective actions. The court determined that the arbitration clause created a significant imbalance, effectively preventing customers from pursuing judicial remedies or participating in class actions.

Companies should proactively assess their dispute resolution clauses to ensure they comply with unfair contract terms provisions, particularly under legislation like the ASIC Act. Clauses that are not clearly communicated, are impractical for consumers due to cost, or are not demonstrably necessary for the business's legitimate interests risk being deemed void. The outcome in Plus500AU v AghaeiRad FCAFC 125 reinforces the judiciary's commitment to protecting consumers from contractual terms that unduly limit their legal recourse, setting a precedent for Australian class action arbitration cases.

This ruling serves as a critical reminder for lawyers drafting or reviewing standard form consumer contracts, particularly in financial services, that arbitration clauses must be transparent and genuinely fair. Businesses should assess whether their dispute resolution clauses could be deemed void under unfair contract terms provisions, especially if they effectively prevent customers from pursuing class actions or judicial remedies.
