Are the Harman undertakings applicable presently?
19 There is no difficulty in concluding that the Harman undertaking may be applicable to an affidavit of evidence filed in the Court in compliance with a court order. The passage from Hearne v Street set out above included in the class of documents which may be the subject of the undertaking, witness statements served pursuant to a judicial direction and affidavits. The plurality cited Central Queensland Cement Pty Ltd v Hardy [1989] 2 Qd R 509; Springfield Nominees at 223; and State Bank of South Australia v Smoothdale (No 2) Ltd (1995) 64 SASR 224 at 229 as indicating the applicability of the undertaking to witness statements, and Medway v Doublelock Ltd [1978] 1 WLR 710; and Re Addstone Pty Ltd (In liq); Ex parte Macks (1998) 30 ACSR 156 as supporting the applicability of the undertaking to affidavits.
20 There is, however, some difference in the authorities on the question of whether affidavits filed in compliance with orders of the Court fixing a timetable for the provision of trial evidence are disclosed under the relevant degree of coercion. Counsel for the Commissioner provided a helpful outline of submissions on this topic.
21 The issue is pertinent in the present case because, in each of the six actions, it may be inferred that the applicants filed the affidavits of Mr Gould in compliance with orders requiring the affidavits containing the lay evidence proposed to be led by them to be filed and served by a nominated date.
22 In Comfort Hotels Ltd v Wembley Stadium Ltd [1988] 1 WLR 872, Hoffman J considered that the fact that a court had made it a condition of a party's ability to lead oral evidence at the trial that notice of the evidence be given in the form of a witness statement, did not mean that a party was compelled to disclose any information or document, as the party could choose to keep the document to himself or herself, at 877.
23 The reasons of Perram J in Hua Wang Bank Berhad v Commissioner of Taxation (No 8) [2013] FCA 1021; (2013) 96 ATR 576 are also pertinent in this respect. That decision concerned, amongst other things, the application of the Commissioner for leave to use the First and Second Leagou Affidavits in the 2011 Proceedings. His Honour noted, at [1], that Leagou had been ordered to file its evidence in chief and that the First and Second Leagou Affidavits had been filed pursuant to that order. On the topic of voluntariness, Perram J said:
[16] It is relevant also, I think, that the affidavit was produced by Mr Gould voluntarily in the course of the Leagou proceeding. There are a number of aspects to this. First, it is true that Leagou had been required by the Court to file, in the form of affidavits, its evidence in chief and that the evidence it served included Mr Gould's affidavit. But this Court's orders placed no legal compulsion on Mr Gould to swear the affidavit. Secondly, there is nothing to suggest that Leagou had it in its power to compel Mr Gould to swear the affidavit nor any evidence that the affidavit was prepared by him in consequence of such an exercise in compulsion. All that was compulsory as a result of the Court's orders was that if Leagou had any affidavits upon which it was going to rely then it had to serve them. That order did not require Mr Gould to do anything.
24 Likewise, in Anglo American Investments Pty Ltd (Trustee) v Commissioner of Taxation [2019] FCA 1027, Logan J said of the First Leagou Affidavit, the first HWBB Affidavit and the Bywater Affidavit, that the making of them had not been the subject of compulsion. They had instead been filed voluntarily in response to a Court order for the filing within a particular time of such affidavits as were proposed to be relied on by a particular party, at [12].
25 In Helicopter Aerial Surveys Pty Ltd v Robertson [2015] NSWSC 2104, Brereton J took a similar view:
[39] Accordingly, I seriously doubt whether in principle the implied obligation attaches to affidavits sworn and served in the ordinary way in the course of proceedings. By reference to "the ordinary way", I exclude affidavits sworn in response to orders for disclosure, such as of the type referred to in Medway v Doublelock. But, in referring above to "the ordinary course", I do not regard a mere timetable requiring affidavits to be used in proceedings to be served by a particular date as amounting to compulsory process. Such a timetable does not compel a party to disclose information that it does not wish to disclose, and it does not compel a witness to disclose any information; it simply fixes a time by which any evidence to be relied on must be served. It is quite distinct from an order which requires a party to make an affidavit deposing to certain matters, which would amount to compulsory process in the relevant sense.
26 On the other hand, in Complete Technology Pty Ltd v Toshiba (Australia) Pty Ltd (1994) 53 FCR 125, Hill J, while discussing legal professional privilege attaching to witness statements filed in accordance with a court's timetabling orders, seemed to consider that the Harman undertaking was applicable, at 132D-133D. Similarly, in Action Scaffolding & Rigging Pty Ltd (in liq) v Citadel Financial Corporation Pty Ltd [2019] FCA 327 at [150], Gleeson J, while noting the doubt expressed by Brereton J in Helicopter Aerial Surveys, regarded the affidavits in question as attracting the Harman undertaking.
27 Several of the authorities bearing upon the issue of coercion more generally were reviewed by Jackson J in Frigger v Trenfield (No 5) [2020] FCA 827. It is not necessary to refer to his Honour's review in detail. Instead, the authorities to which I have referred indicate that it is appropriate to accept the Commissioner's submission that, on the present state of the authorities, there is at least some uncertainty as to the applicability of the Harman undertaking in circumstances of the present kind. The resolution of that uncertainty should await a case in which the Court has the benefit of submissions on all sides.
28 Given the uncertainty, I consider it appropriate for the Court to proceed conservatively, that is, to assume that the Harman undertakings are applicable and that the Commissioner does require the release from the undertakings which he seeks.
