"Where litigation has not been commenced at the time of the communication, it has to be 'reasonably in prospect'; this does not require the prospect of litigation to be greater than 50% but it must be more than a mere possibility". (4) It is not enough for a party to show that proceedings were reasonably anticipated or in contemplation; the party must also show that the relevant communications were for the dominant purpose of either (i) enabling legal advice to be sought or given, and/or (ii) seeking or obtaining evidence or information to be used in or in connection with such anticipated or contemplated proceedings. Where communications may have taken place for a number of purposes, it is incumbent on the party claiming privilege to establish that the dominant purpose was litigation. If there is another purpose, this test will not be satisfied: Price Waterhouse (a firm) v BCCI Holdings (Luxembourg) SA[1992] BCLC 583 , 589-590 (cited in Tchenguiz at [54]-[55]); West London Pipeline and Storage Ltd v Total UK Ltd at [52]. 12. In relation to the Court's approach to the assessment of evidence in support of a claim for privilege, it has been stated that it is necessary to subject the evidence "to "anxious scrutiny" in particular because of the difficulties in going behind that evidence" – per Eder J in Tchenguiz at [52]. "
"(3) It is, however, difficult to go behind an affidavit of documents at an interlocutory stage of proceedings. The affidavit is conclusive unless it is reasonably certain from: (a) the statements of the party making it that he has erroneously represented or has misconceived the character of the documents in respect of which privilege is claimed: Frankenstein v Gavin's House to House Cycle Cleaning and Insurance Co, per Lord Esher MR and Chitty LJ; Lask v Gloucester Health Authority. (b) the evidence of the person who or entity which directed the creation of the communications or documents over which privilege is claimed that the affidavit is incorrect: Neilson v Laugharane (the Chief Constable's letter), Lask v Gloucester HA (the NHS Circular), and see Frankenstein v Gavin's House to House Cycle Cleaning and Insurance Co, per A L Smith LJ. (c) the other evidence before the court that the affidavit is incorrect or incomplete on the material points: Jones v Montivedeo Gas Co; Birmingham and Midland Motor Omnibus Co v London and North West Railway Co; National Westminster Bank plc v Rabobank Nederland.” The law relating to "litigation privilege" (1) The burden of proof is on the party claiming privilege to establish it – see, for example, West London Pipeline and Storage v Total UK[2008] 2 CLC 258 at [50]. (2) An assertion of privilege and a statement of the purpose of the communication over which privilege is claimed in a witness statement are not determinative and are evidence of a fact which may require to be independently proved. The court will scrutinise carefully how the claim to privilege is made out and the witness statements should be as specific as possible – see, for example, Sumitomo Corporation v Credit Lyonnais Rouse Ltd (14 February 2001 ) at [30] and [39] (Andrew Smith J); West London Pipeline and Storage Ltd v Total UK Ltd[2008] EWHC 1729 (Comm) at [52], [53], [86] (Beatson J); Tchenguiz v Director of the SFO[2013] EWHC 2297 (QB) at [52] (Eder J). (3) The party claiming privilege must establish that litigation was reasonably contemplated or anticipated. It is not sufficient to show that there is a mere possibility of litigation, or that there was a distinct possibility that someone might at some stage bring proceedings, or a general apprehension of future litigation – see, for example, United States of America v Philip Morris Inc[2004] EWCA Civ 330 at [68]; Westminster International v Dornoch Ltd[2009] EWCA Civ 1323 at paras [19] – [20]. As Eder J stated in Tchenguiz at [48(iii)]: "
