Key facts
- A shareholder, Rosherville, intends to seek court approval to sue former ASX directors and officers.
- The legal action concerns the abandoned blockchain-based CHESS clearing and settlement project.
A shareholder plans to seek court approval to sue former officers and directors of the Australian Securities Exchange (ASX) over the company's abandoned CHESS blockchain project. The shareholder alleges breaches of duty related to the project's failure.

This development highlights potential governance failures and financial repercussions for the ASX stemming from the costly abandonment of its CHESS replacement project, impacting investor confidence and the company's reputation.
The Australian Securities Exchange (ASX) announced that a shareholder, Rosherville, intends to seek court approval to initiate a statutory derivative action against certain former officers and directors. This legal move stems from allegations of breaches of duty concerning the company's failed blockchain-based Clearing House Electronic Subregister System (CHESS) project.
Under Australia's Corporations Act 2001, a statutory derivative action allows a shareholder to bring legal proceedings on behalf of a company if the company itself is unlikely to do so, requiring court leave. ASX clarified that there are no allegations against the exchange itself.
The CHESS replacement project, aimed at modernizing Australia's share settlement system, was halted in November 2022 following an independent review that identified significant issues with its design and delivery. ASX subsequently abandoned the original blockchain approach and is developing a new replacement plan.
Following the announcement, shares of the bourse operator fell as much as 2.5% to A$55.68, marking their largest intraday decline since July 3.
