45 NGC accepts that the conduct of Hickeys, in sending the Hiroyuki Narui Statement to Leda, amounted to a disclosure of the document and its content by NGC to Leda. NGC also accepts that the disclosure was knowing and voluntary within the meaning of s 122(2). That being so, s 122(2) does not prevent the use of the statement in evidence unless the disclosure was made in any of the circumstances specified in paragraphs (a) to (d) of s 122(2) (or 122(5) operates to displace the operation of s 122(2)).
46 NGC relies, in this respect, on s 122(2)(a) and the proposition that the relevant disclosure, knowing and voluntary though it was, occurred "in the course of making a confidential communication". The expression "confidential communication" takes its meaning from s 117(1):
" confidential communication means a communication made in such circumstances that, when it was made:
(a) the person who made it, or
(b) the person to whom it was made,
was under an express or implied obligation not to disclose its contents, whether or not the obligation arises under law."
47 At the time of the disclosure on 19 December 2002, there was in force the confidentiality deed made on 10 July 2002 between NGC and Leda. The deed related to the parties' intention to seek to negotiate "a contract to acquire the property detailed in item 1 and/or enter into a joint venture relationship with parties for the acquisition and development of the property detailed in item 1" (these words appear in item 2 of the deed's schedule under a heading "purpose of disclosure"; the property in item 1 is the Kings Forest property owned by NGC). The deed made provision for Leda (called "Recipient Party") to have access to "Confidential Information of the Disclosing Party" (NGC) for the purpose stated in item 1. By clause 3, Leda, as "Recipient Party", agreed, "[i]n consideration of the Disclosing Party allowing the Recipient Party to have access to the Confidential Information", that it would "keep and well ensure that its employees keep confidential the Confidential Information unless and until the parties agree that the Confidential Information is in the public domain other than by breach of this Agreement". Clause 4 imposed specific non-disclosure obligations on Leda with respect to the "Confidential Information". The obligations were contractual obligations.
48 The term "Confidential Information" was defined by the deed as follows:
" 'Confidential Information' means all information disclosed by the Disclosing Party to the Recipient Party, including all reports, plans, correspondence, trade secrets, ideas, know how, concepts or any information whether in writing or otherwise relating in any way to the matter or matters described in item 1 of the Schedule and all other information relating to the Disclosing Party or any of its parent companies, subsidiaries or its directors, affairs or businesses, which are not in the public domain and includes any such information in the Disclosing Party's power, possession or control concerning or belonging to any other person."
49 The letter of 19 December 2002 with which Hickeys sent the Hiroyuki Narui Statement (and other documents) to Mr Van Rij of Leda was prepared and signed by Mr Hodgson, a solicitor employed by Hickeys. The letter stated no reason for sending the documents. After commenting that certain annexures were not being sent, the latter concluded:
"We look forward to hearing from you."
50 Mr Hodgson deposed that he sent the letter and documents in accordance with an oral direction given to him by Mr Brinsmead, a partner of Hickeys. According to Mr Hodgson, Mr Brinsmead said to him on 19 December 2002:
"You need to send Leda a copy of the three Hiroyuki Narui statements and the three Shigeo Narui statements … Leda is entitled to them as part of the due diligence process. We cannot hide them from Leda."
51 This suggests that a due diligence on the part of Leda was in progress on 19 December 2002. The deed of 10 July 2002 was, clearly enough, intended to facilitate such a process. The plaintiffs maintain that the due diligence (and, accordingly, the regime provided for in the deed) had come to an end before 19 December 2002.
52 The plaintiffs point, in this connection, to the two letters of 16 September 2002 sent by Hickeys to Leda, one on behalf of NGC and the other on behalf of "the Narui family". The letter set out, in one case, the "fundamental terms" on which the client "will agree to enter into contractual arrangements" and, in the other, "the terms of what we understand is an intended agreement between you [ie, Leda] and this family". Leda, by endorsement on each letter also dated 16 September 2002, indicated agreement to the terms contained in the letter.
53 It is the contention of the plaintiff that, although formal contracts were not entered into until August 2003, the events of 16 September 2002 effectively marked the end of the due diligence process and therefore of the regime of contractual confidentiality created by the deed of 10 July 2002.
54 Some support for that view is derived from one of the letters of 16 September 2002. The first of the letters says:
"You [ie, Leda] agree that you will acquire all of the shares in Narui Gold Coast Pty Ltd on the basis that you have conducted full and appropriate due diligence of all of the assets and liabilities of Narui Gold Coast Pty Ltd."
55 The plaintiffs suggest that Leda, by indicating acceptance of the content of this letter, gave an immediate and operative acknowledgment that it had, as of 16 September 2002, completed a due diligence examination. An alternative construction is that Leda was indicating by its acknowledgment that the ultimate acquisition - which at 16 September 2002 lay in the future - would be on the basis that a "full and appropriate due diligence" had occurred as at the point of the ultimate acquisition.
56 This second construction is, my mind, supported by three matters. The first is the statement in the 16 September 2002 letter that warranties by the seller of the NGC shares would be limited to the vendor's unencumbered title to the shares sold and the vendor's capacity to sell those shares. This followed an acknowledgment and agreement by Leda that it would acquire NGC "subject to" a number of specific matters concerning litigation and disputes, plus
"All other assets, liabilities or issues concerning Narui Gold Coast Pty Ltd whatsoever."
57 It is reasonable to think that, because of the basis of sale thus indicated by the vendor, it was expected and intended that Leda would continue with investigations.
58 The second matter is that the letter of 16 September 2002 left open the clear possibility that there would ultimately be no sale. There are references in it to "any Contract of Sale" and "any agreement for the sale and purchase of the shares". The owners or holders of the shares were not parties to the letter: Hickeys represented merely that it acted for NGC, the putative target company. NGC and Leda were still, at that point, dealing with a potential transaction and it is reasonable to think that Leda would be continuing with the established due diligence investigation.
59 Third, due diligence in fact continued after 16 September 2002. Notes of 17 September 2002 identify three matters - "Harrison: Revenue", "Barr: Lease" and "House: Lease" - against a notation "Hickey Lawyers/Einfeld to do a full review" and "Vetted by John Meggitt and/or another". Mr Meggitt was Leda's in-house lawyer and it seems clear enough that ongoing inquiry by him in relation to the particular matters (at least) was envisaged.
60 It seems to me sufficiently clear that the purpose, on the part of Leda, of considering whether to enter into a "contract" or "joint venture relationship" as envisaged by the definition of "Specific Purpose" did not become accomplished or exhausted when, on 16 September 2002, Leda indicated agreement to the terms contained in the two letters from Hickeys. Pursuit of that purpose by Leda remained a live matter until Leda became party to the formal contracts of August 2008.
61 The statement attributed by Mr Hodgson to Mr Brinsmead (see paragraph [50] above) was, in my view, an accurate statement, indicating that giving of the Hiroyuki Narui Statement to Leda occurred under the umbrella of the confidentiality deed of 10 July 2002.
62 That deed was the source of an express obligation on the part of Leda of the kind referred to in the definition of "confidential communication" in s 117(1) of the Evidence Act.
63 It follows that NGC's reliance on s 122(2)(a) is well placed and that that provision causes the effect that s 122(2) would otherwise have in light of NGC's knowing and voluntary disclosure to be denied, with the result that the barrier created by s 119 exists.
The second occasion - assessment
64 It is acknowledged on both sides that documents in which client legal privilege subsists are immune from seizure upon execution of a search warrant and that a court may order the return of the privileged material.
65 The plaintiffs say that, as a result of the seizure of the Hiroyuki Narui Statement by the police in execution of the search warrant at Leda's premises, actual confidentiality in the Hiroyuki Narui Statement was lost and that the quality essential to the maintenance of privilege was accordingly also lost. Furthermore, the plaintiffs say, the sole step taken by NGC to assert a claim for privilege was not pressed and, in the face of the police refusal to deliver up the document, Hickeys merely let the matter drop. This, it is said, was inconsistent with any real intention of NGC to maintain the privilege.
66 The police obtained full knowledge of the content of the Hiroyuki Narui Statement as a result of the execution of the search warrant. NGC points out that there is no evidence that it had any knowledge of the seizure at the time it occurred. It should be inferred, in my view, that it did not. NGC also points out that there was no action by NGC itself, in or about the seizure, that was inconsistent with the maintenance of privilege and, therefore, no basis on which consent to disclosure could be implied.
67 I am satisfied that "disclosure" of the content of the Hiroyuki Narui Statement to the police occurred by reason of the seizure. But the disclosure was not a disclosure by NGC (s 122(2)); nor was it "with the express or implied consent" of NGC (s 122(4)). The disclosure therefore did not destroy the privilege belonging to NGC.
68 I am also satisfied that inaction of NGC for some eight months following the seizure cannot be construed as ex post facto "consent" of NGC relevant to s 122(4) or some other form of waiver: see paragraph [24] above.
The third occasion - assessment
69 There is a factual question here as to the part the Hiroyuki Narui Statement played in the interview of Hiroyuki Narui by the police.
70 Handwritten notes made by Mr Monaghan of Hickeys at the interview begin by listing the persons present. They continue:
"No recording.
3 statements.
Investigation about false TSC documents."
