Jubilee Mines NL v Riley

Jubilee Mines NL sued former shareholder Riley, alleging negligence in failing to disclose information to the Australian Securities Exchange (ASX). The dispute centred around the obligations of continuous disclosure under the Corporations Law and the ASX Listing Rules, particularly regarding the disclosure of information that would influence investors. Riley had failed to release information which Jubilee Mines NL claimed had a material effect on the price or value of securities. The court was tasked with determining whether Riley's failure to disclose constituted a breach of the ASX Listing Rules and if it amounted to negligence under the Corporations Law. Additionally, the court had to interpret the terms "material effect on the price or value of securities" and "information," and whether relevant circumstances must also be disclosed.

The court examined the history of continuous disclosure in Australia, considering both statutory and regulatory frameworks. It assessed the content of information required to be released, and whether additional relevant circumstances must also be disclosed. The court's interpretation hinged on the specific facts of the case. Furthermore, the court evaluated the impact of evidence introduced without objection at the trial stage. The court concluded that Riley's failure to release information did breach the ASX Listing Rules and constituted negligence under the Corporations Law, as the information had a material effect on the price or value of securities.

The court allowed the appeal, finding that the evidence presented justified the claim that the non-disclosure had a significant impact on investor decisions. The court determined that the information in question was indeed material and should have been disclosed. The ruling underscored the importance of adhering to continuous disclosure obligations to maintain market integrity and protect investor interests. The court's decision emphasised the necessity for companies to disclose not just the information itself, but also relevant circumstances that could influence investment decisions.
