CTC Resources Nl v Australian Stock Exchange Ltd P18/2000

CTC Resources NL (CTC) and Australian Stock Exchange Ltd (ASX) were the parties in this matter before the High Court of Australia. CTC sought to challenge a decision of the Full Federal Court concerning the interpretation and application of the Corporations Law, specifically in relation to the ASX's power to suspend or delist a company from the stock market. The dispute arose from the ASX's decision to suspend CTC's shares from quotation, which CTC contended was unlawful.

The central legal issue before the High Court was whether the ASX, in exercising its power to suspend or delist a company under its Listing Rules, was acting in a manner that was amenable to judicial review under the *Administrative Decisions (Judicial Review) Act 1977* (Cth) (ADJR Act). This involved determining whether the ASX's decision-making process in this context constituted "an administrative decision other than a decision of the kind specified in section 3(1) of the ADJR Act" and whether the ASX itself was an "officer or body" for the purposes of the ADJR Act.

The High Court, comprising Gummow and Callinan JJ, held that the ASX's decision to suspend CTC's shares was not a decision amenable to judicial review under the ADJR Act. Their Honours reasoned that the ASX, in making decisions regarding the listing and suspension of companies, was not exercising a "public power" in the sense contemplated by the ADJR Act. Instead, the ASX was acting pursuant to powers derived from its own rules and its contractual relationship with listed companies, rather than from a statutory grant of authority. The Court distinguished the ASX's role from that of a traditional government body exercising statutory powers, emphasizing that its disciplinary and listing functions were primarily contractual and self-regulatory.

Consequently, the High Court dismissed CTC's appeal, upholding the Full Federal Court's decision that the ADJR Act did not provide a basis for judicial review of the ASX's decision to suspend CTC's shares.
