Hudson Securities Pty Ltd v Australian Stock Exchange

Hudson Securities Pty Ltd (Hudson) appealed to the Court of Appeal of New South Wales against a decision of the Supreme Court concerning its obligations under the business rules of the Australian Stock Exchange (ASX). The dispute arose when the ASX sought to investigate certain trading activities and required Hudson, a member firm, to ensure its officers appeared to give information. Hudson refused to comply with this requirement unless certain conditions were met, leading to the ASX's assertion that Hudson had failed to comply with its business rules.

The primary legal issues before the Court of Appeal were whether Hudson had failed to comply with the ASX's business rules by refusing to produce its officers for examination without conditions, and whether the ASX was entitled to require that these officers give confidentiality undertakings as a condition of their appearance.

The Court of Appeal held that Hudson had indeed failed to comply with the business rules. It reasoned that the rules clearly empowered the ASX to require a member to cause its officers to appear and give information, and that Hudson's conditional refusal constituted a failure to comply. However, the Court found that the ASX was not entitled to impose a requirement for confidentiality undertakings on the officers. The Court's reasoning was that while the business rules provided for the examination of officers, they did not grant the ASX the power to impose such conditions on the officers themselves, separate from the member firm's obligations.

The appeal was allowed in part. Paragraph (e) of the Supreme Court's order of 16 December 1999 was set aside. The appellant, Hudson Securities Pty Ltd, was ordered to pay three-quarters of the respondent's costs of the appeal, with no other orders as to costs of the appeal.
