The recent High Court decision in California State Teachers' Retirement System & Ors v Boohoo Group plc [2026] EWHC 335 (Comm) underscores how questions of reliance, causation and case management may shape the future of securities claims against listed corporates accused of misleading the market.
The decision clarifies that there is no hard and fast approach to the case management of claims under section 90A of the Financial Services and Markets Act 2000 ("FSMA"). Instead, the Court emphasised flexibility, with the correct approach to be determined by the circumstances of each case.
More broadly, the case is a significant development in one of the highest-profile ESG claims currently before the English courts. If successful, it may provide a precedent for other claimants considering similar ESG claims in future, and provide a further route by which investors can hold listed corporates accountable for "greenwashing" and other breaches of ESG standards. We would therefore expect claimant lawyers and litigation funders to be closely monitoring the progress of the matter, with a view to bringing similar claims against corporate defendants in future.
