(a) the onus is on the party claiming privilege to show that the documents for which privilege is claimed are privileged: Grant v Downs (1976) 135 CLR 674 at 689; Walker Corporation Pty Ltd v Sydney Harbour Foreshore Authority [2008] NSWLEC 247, 161 LGERA 86;
(b) the dominant purpose must exist at the time the document is brought into existence: Singapore Airlines v Sydney Airports Corporation [2004] NSWSC 380 at [19] per McDougall J. This point did not arise on the unsuccessful appeal: Sydney Airports Corporation Ltd v Singapore Airlines Ltd [2005] NSWCA 47 at [9];
(c) dominant purpose is a question of fact: Esso Australia Resources Ltd v Commissioner of Taxation (1999) 201 CLR 49; Walker at [91]; Sydney Airports Corporation Ltd at [7]. Dominant purpose must be determined objectively having regard to all the circumstances, but the subjective intention of the author and of the person or authority under whose direction the document was prepared is entitled to weight;
(d) under s 119, if the document would have been prepared irrespective of the intention to obtain professional legal services, it will not satisfy the test: Grant at 688; Sydney Airports Corporation Ltd at [6]; Walker at [9];
(e) the Court of Appeal has approved the test of "dominant" purpose as clear paramountcy, or as the ruling, prevailing or most influential purpose; yet has observed that a purpose may not be dominant even if it is greater than another purpose or is the most important purpose: Sydney Airports Corporation Ltd at [7], [49] per Spigelman CJ (Sheller JA and M W Campbell AJA agreeing). It has been commented that it is somewhat difficult to reconcile the observation in that case that the most important purpose does not necessarily mean the dominant purpose with the proposition earlier adopted that dominant purpose indicates the most influential purpose: Odgers, Uniform Evidence Law, (8th ed, 2009) 565 fn 72.
(f) the Court has power to examine documents in cases where there is a disputed claim, and it should not be hesitant to exercise such a power: Esso Australia Resources Ltd v Commissioner of Taxation of the Commonwealth of Australia (1999) 201 CLR 49 at [52], Walker at [15].
(g) for litigation to be reasonably "anticipated", as a general rule there must be at least a real prospect of litigation, as distinct from a mere possibility, but it does not have to be more likely than not: Mitsubishi Electric Australia Pty Ltd v Victorian WorkCover Authority (2002) 4 VR 332 (CA) at [20] per Batt JA (Charles and Callaway JJA agreeing); quoted in Singapore Airlines at [44].
Evidence as to privilege
8 The respondents claimed client legal privilege in respect of eleven documents numbered 31 to 41 in its discovery list, described as "Walker Breach Report", various emails all titled "Compliance (Confidential) - Walker Corporation at [a specified address]", notes or reports of a case conference, and an email titled (and attaching) "final maps" of the applicant's land.
9 I have inspected the documents and it is common ground that they are confidential.
