A director and former officer of the Australian Securities Exchange (ASX) who is also a shareholder is seeking to hold former executives accountable for the exchange's troubled blockchain initiative. Through Rosherville Pty Ltd, the shareholder advised the ASX of plans to file a statutory derivative action in the Federal Court of Australia on ASX's behalf. The exchange detailed the shareholder's intentions in an official notice of the proposed statutory derivative action.

Rosherville's proposed case would be brought under sections 236 and 237 of Australia's Corporations Act 2001. The shareholder alleges that certain former ASX directors and officers breached their duties in connection with the previous Clearing House Electronic Subregister System (CHESS) replacement project. CHESS underpins the clearing, settlement, and registration of ASX-listed equities, making it one of the most critical pieces of Australia's financial-market infrastructure.

ASX stressed in a statement that the allegations are directed solely at former individuals and not against the exchange itself. The company has not disclosed the names of the former officials involved or provided details regarding the specific conduct alleged by Rosherville. If the court grants leave, the case could test the boundaries of director accountability for large-scale technology failures under Australian corporate law.

Statutory Derivative Action Process

Because a statutory derivative action is a claim brought in the name of a company for an alleged wrong committed against the company, the case cannot proceed automatically. Rosherville must first convince the Federal Court to grant leave to bring the proceedings on ASX's behalf.

Under Section 237, the court evaluates several factors, including whether the applicant is acting in good faith, whether the action serves the company's best interests, and whether there is a serious question to be tried. Additionally, applicants generally must provide written notice to the company at least 14 days before applying to the court for leave.

Background on the Blockchain CHESS Project

The dispute centers on ASX's previous attempt to replace CHESS with a blockchain-based system. ASX initiated the replacement process in 2016, promoting it as a major modernization of Australia's financial-market infrastructure and choosing distributed-ledger technology developed in conjunction with Digital Asset. The project was among the most ambitious attempts by a major global exchange to deploy blockchain for core post-trade operations.

Following an external review in November 2022 that uncovered significant design shortcomings and unmet exchange demands, ASX suspended the project. By 2023, the exchange officially dropped the blockchain-based strategy and began exploring alternative technologies.

Previous $14.4 Million ASIC Penalty

The aborted project has already resulted in regulatory enforcement from the Australian Securities and Investments Commission (ASIC). ASIC determined that ASX had no basis to inform the market in February 2022 that the project was in good shape and moving forward on its launch timeline.

ASX was found to have engaged in misleading conduct related to the project and accepted this finding in 2026. Consequently, the Federal Court fined ASX $14.4 million and directed the exchange to contribute $2.1 million toward ASIC's legal costs.

This regulatory case is distinct from Rosherville's proposed derivative action, which seeks permission to pursue claims against former personnel rather than the exchange itself. ASX stated that it will continue updating the market as the matter develops, fulfilling its continuous disclosure obligations. The next key milestone will be whether the Federal Court grants Rosherville leave to proceed.
