The Privy Council has decided that shareholders no longer have an automatic right to disclosure of a company's privileged documents, supporting the High Court's finding in Aabar v Glencore that the original proprietary justification for the "shareholder rule" was inconsistent with the proper analysis of a registered company as a separate legal entity from its shareholders. It also rejected the argument that the company-shareholder relationship could be said to attract joint interest privilege. Our Insight considers the impact of this decision.

The Competition and Markets Authority is consulting on draft guidance on the price transparency provisions of the Digital Markets, Competition and Consumers Act 2024 in respect of invitations to purchase. The guidance will be of interest to consumer-facing businesses: it provides numerous examples both of prohibited "drip pricing" practices (not all of which are straightforward), as well as ways to ensure compliance when presenting price information.

AI can offer significant benefits for advertising, such as cost efficiency and enhanced personalisation. But businesses should be mindful of the legal and ethical considerations to avoid misleading consumers. Our update on marketing law looks at the regulatory landscape for AI use in advertising and marketing, reviews recent guidance and provides practical tips.
