Disclosure and inspection of documents – Legal professional privilege. The Court of Appeal, Civil Division, allowed, in part, an appeal by Vincent Tchenguiz and others against a decision of the Commercial Court refusing them permission to make use of documents disclosed inadvertently by the Serious Fraud Office in the course of proceedings. The court held, amongst other things, that it had not been obvious that the documents, which were subject to legal professional privilege, had been disclosed by mistake.
