Disclosure and inspection of documents – Public interest immunity. The Competition and Markets Authority (the CMA) was granted various warrants under s 28 of the Competition Act 1998, concerning an investigation into suspected anti-competitive behaviours in relation to a number of pharmaceutical drugs. The defendant (Concordia) applied to have the warrant granted in respect of it discharged to the extent that it applied to certain medicines. Prior to that application being heard, the Chancery Division considered whether Concordia could have sight of certain confidential material submitted in support of the CMA's application or whether non-disclosure could be justified, as the CMA submitted, on the ground of public interest immunity.
