An Australian Securities Exchange (ASX) shareholder has notified the exchange that it intends to seek permission from the Federal Court to bring a derivative action against former ASX officers and directors over their alleged involvement in the failed blockchain-based overhaul of the Clearing House Electronic Subregister System (CHESS).

In a statement issued on Wednesday, ASX said Rosherville Pty Ltd had formally notified the exchange of its proposal to apply for leave to commence proceedings under sections 236 and 237 of Australia's Corporations Act. If the court grants that leave, Rosherville would be permitted to pursue the action on behalf of ASX itself, targeting former leaders who are accused of breaching their statutory duties in connection with the abandoned project.

The exchange said the allegations are not directed at ASX as a corporate entity but at individuals who formerly held officer or director positions. ASX did not name the former officials, did not provide details of the specific breaches alleged, and did not disclose the remedies that Rosherville intends to seek. The Federal Court has not yet considered whether the proposed case has any reasonable prospect of success.

The planned lawsuit adds a new layer of legal risk to what has become one of Australia's most scrutinised financial technology failures. The failed CHESS replacement was originally expected to make ASX the first securities exchange in the world to run its core clearing and settlement infrastructure on blockchain technology. Instead, the project was delayed repeatedly, criticised by consultants, abandoned in 2023, and ultimately led to regulatory action by the Australian Securities and Investments Commission (ASIC).

Background of the CHESS replacement project

CHESS, or the Clearing House Electronic Subregister System, has been the backbone of Australia's equity market since its launch in the 1990s. It records shareholdings, handles the settlement of trades, and manages the transfer of ownership between buyers and sellers. For decades, the system has operated reliably, but by the mid-2010s ASX concluded that it needed a major upgrade to remain fit for purpose in a rapidly evolving financial landscape.

In 2016, ASX began exploring a replacement system. The exchange eventually selected a distributed-ledger technology platform being developed in partnership with New York-based Digital Asset. The project attracted enormous attention because it promised to modernise clearing and settlement using the same kind of technology that underpins cryptocurrencies such as Bitcoin and Ethereum, but in a regulated, institutional setting. In December 2017, ASX announced that it intended to become the first securities exchange anywhere in the world to deploy blockchain for its core post-trade services.

At the time, the project was seen as a pioneering move that could give Australia a competitive edge in financial infrastructure. ASX leaders described the technology as transformative, and the exchange invested significant time, money and institutional credibility in the effort. However, the project also carried substantial complexity. Replacing a system as important as CHESS requires careful coordination with brokers, clearing participants, registry operators, and regulators. Any change must preserve the integrity of settlement, manage risk, and maintain the trust of investors and listed companies.

Over the following years, the intended launch date was postponed several times. ASX originally aimed to deliver the new system in 2020 or 2021, but technical challenges and design issues kept pushing the timeline further out. In February 2022, ASX told the market that the project was progressing well and remained on track for an April 2023 launch. That statement later became the centre of a regulatory investigation.

Collapse of the blockchain project

In November 2022, ASX abruptly paused the project after commissioning a review by consulting firm Accenture. The review found significant problems with the system's design, its ability to meet ASX's requirements, and the overall readiness of the technology. The findings were a major embarrassment for the exchange and triggered questions about whether management had been transparent with investors about the project's real status.

By May 2023, ASX formally abandoned blockchain as the basis for the CHESS replacement. The exchange said it would consider more conventional technology options instead, effectively admitting that the ambitious experiment had failed. The decision represented a major write-down of both financial value and reputational capital. It also sparked a broader debate about whether regulators and exchange boards had been too willing to embrace unproven technology.

The failed project became a test case for the governance of large-scale technology transformations in Australia's financial sector. Market participants pointed to a range of issues, including inadequate oversight by the ASX board, overconfidence in the capabilities of the vendor's technology, and insufficient challenge from senior executives. Some also questioned whether ASX had followed proper procurement processes and whether it had pressured internal teams to meet unrealistic deadlines.

ASIC legal action and penalty

In August 2024, ASIC sued ASX in the Federal Court. The regulator alleged that ASX had no reasonable basis for telling the market in February 2022 that the blockchain replacement project was progressing well and on track for an April 2023 launch. ASIC argued that ASX was aware, or should have been aware, of serious problems with the project well before that announcement.

ASIC described the episode as a collective failure by ASX's board and senior executives. The regulator said the misleading statements had the potential to harm investors by creating a false impression of the exchange's risk profile and the likelihood of a successful delivery. The case was closely watched because it raised important questions about how companies should communicate with the market about complex, high-risk technology projects.

On June 17, 2026, ASX admitted to misleading conduct in connection with the blockchain replacement project. The admission came after lengthy negotiations and marked a significant victory for the regulator. On July 3, 2026, the Federal Court ordered ASX to pay a A$14.4 million penalty and A$2.1 million toward ASIC's costs. The penalty was one of the largest ever imposed for misleading disclosure in Australia and closed the regulator's case only a few weeks before Rosherville notified the exchange of its proposed derivative action.

What is a statutory derivative action?

A derivative action is a legal proceeding brought by a shareholder on behalf of the company itself, rather than in the shareholder's personal capacity. In Australia, such actions are governed by Part 2F.1A of the Corporations Act. Section 236 allows a member to bring proceedings on behalf of a company, but only with the leave of the court. Section 237 sets out the criteria the court must consider before granting that leave.

To obtain leave, a shareholder must usually demonstrate that the company is not itself willing to bring the proceedings, that the proposed action is in the best interests of the company, and that the applicant is acting in good faith. The court also considers whether the shareholder has given the company reasonable notice of the intended application and whether there is a serious question to be tried.

Derivative actions are rare because they are difficult and expensive to mount. Shareholders must be prepared to take on significant legal costs, and courts are generally reluctant to interfere with the discretion of a properly constituted board. However, the CHESS project may represent the kind of case where a derivative action is appropriate, particularly if the former directors and officers are alleged to have breached their duties of care and diligence or their duties to act in good faith and for a proper purpose.

In this case, Rosherville's proposed target is not the ASX itself but individuals who previously served as directors or officers. The action would seek to hold those individuals accountable for any losses the company suffered as a result of their alleged conduct. If successful, any compensation recovered would flow to ASX, not directly to the shareholder bringing the action.

Rosherville will need to convince the Federal Court that it is appropriate to grant leave for the proceedings to continue. That will likely involve a detailed examination of the evidence, including the Accenture review, internal ASX communications, board minutes, and public announcements made during the project's lifetime. The court will also need to consider whether ASX, through its current board and management, had a valid reason for declining to bring the action itself.

Implications for corporate governance

The proposed lawsuit could have significant implications for corporate governance in Australia. If the court grants leave and the shareholder ultimately succeeds, it would send a strong signal that directors and officers can be held personally liable for failures to properly oversee major technology projects. That would be particularly important in a period when many companies are rushing to adopt artificial intelligence, blockchain, and other emerging technologies without fully understanding the risks.

It would also encourage shareholders to scrutinise board decision-making more closely, especially in cases where management has made bold public statements about the expected success of a project. The ASX case is notable because the initial statements about the CHESS replacement were made with apparent confidence, but the project collapsed only months later. That disconnect between public messaging and internal reality is at the heart of the shareholder's allegations.

For ASX, the litigation adds to a period of intense pressure. The exchange has already paid a substantial penalty to ASIC and admitted to misleading conduct. Now it faces the prospect of further litigation funded by a shareholder seeking to recover losses from former leaders. Even if the derivative action is unsuccessful, the need to defend it could be costly and distracting for the exchange's current management.

The case also raises questions about the viability of complex technology partnerships between established financial institutions and smaller technology vendors. Digital Asset, the company that built the original blockchain platform, was not named in the ASIC proceedings and has not been publicly accused of wrongdoing. But the story of the CHESS replacement has become a cautionary tale for exchanges and clearing houses around the world.

Market participants have noted that the core idea of using blockchain for clearing and settlement remains appealing in theory, but the ASX experience demonstrates that the transition from theory to practice is fraught with difficulty. The need for extreme reliability, low latency, and strict regulatory compliance means that even small design flaws can become catastrophic. In that context, the absence of adequate testing and independent verification may be seen as a major failure of oversight.

The Federal Court has not yet scheduled a hearing on Rosherville's application for leave. Nor has ASX indicated how it intends to respond to the shareholder's notice. The matter is likely to attract continued attention from institutional investors, corporate lawyers, and regulators who are watching to see whether this becomes a landmark case in Australian corporate law.
