Tchenguiz and another v Director of the Serious Fraud Office and others and other cases [2013] EWHC 2297 (QB), [2013] All ER (D) 357 (Jul)
It was settled law that litigation privilege would attach to a document where the document had been produced for the dominant purpose of obtaining information or advice in connection with pending or contemplated litigation, or of conducting or aiding in the conduct of such litigation. If the documents were so privileged, then subject to any loss or waiver of privilege, the privilege could not be overridden by any other public interest. The mere fact that a document was produced for the purpose of obtaining information or advice in connection with pending or contemplated litigation, or of conducting or aiding in the conduct of such litigation was not sufficient to founder a claim for litigation privilege. It was only if such purpose was one which could properly be characterised as the “dominant purpose” that such claim for litigation privilege could properly be sustained.
