Applicant's Witnesses
30 Mr David Huang is presently employed as the Chief Operating Officer of the applicant. He commenced his employment in 2014, first as the IT Manager which position he held until 2020. As the IT Manager he was primarily responsible for the development and maintenance of the IT systems of the applicant, as well as for system security. In July 2020, he was promoted to the position of Chief Information Officer. He continued to be responsible for IT security and system development, though at a higher level of responsibility as a member of the senior management team. He was further promoted in April 2021, to his current position of Chief Operating Officer. As might be expected, the Chief Operating Officer is responsible for the day-to-day management of the business of the applicant.
31 Mr Huang's evidence described the business of the applicant in some detail, the history of its growth, the number of employees engaged at material points in time, the development by it of various brands for the sale of categories of products and the division of responsibilities within the applicant by compartmentalisation into separate teams. There is the Category Team, responsible for identifying trends and products in the marketplace and the analysis of data in order to determine which products should be recommended to the Buyer Team for acquisition. The Buyer Team is responsible for investigating new potential suppliers and products including the sourcing of products from individual suppliers, reviewing and sampling products and the maintenance of relationships with existing suppliers. The Product Compliance Team identifies relevant regulatory or legal standards applicable to each product. The Quality Control (QC) team is responsible for quality, safety and product testing in order to ensure that products offered for sale comply with the quality standards as determined by the applicant and applicable external standards. The Data Team is responsible for analysing data and acts as project manager to assist other stakeholders within the business of the applicant. The IT team, as one might understand, is responsible for the development, maintenance and management of the information technology systems that the applicant requires to conduct its business. The Shipping Team acts as account managers in order to manage relationships with various online marketplaces and is responsible for product promotion. The Customer Service Team deals with questions, concerns and feedback from purchasers of products. Finally, the Warehouse Team is responsible for delivery, storage and general warehouse operations.
32 That the business of the applicant is substantial is revealed by three facts. Currently the applicant occupies approximately 96,700 m² of warehouse space in Melbourne, has 400 employees (of which 110 are employed in China) and its annual turnover exceeds $300 million.
33 The products offered for sale by the applicant are sourced from overseas manufacturers, predominantly in China. The business is vertically integrated into seven main category groups comprising bedding, home office and appliances, fitness, entertainment, building materials, home living and indoor furniture, kids and outdoor furniture, garden, outdoor living and tents, tools and outdoor activities and research and development.
34 The applicant is competitive with a large number of other online retailers. At the time of the proceeding, the applicant offered for sale approximately 6000 individual product lines which it obtained from approximately 400 active suppliers in China. In contrast, when Mr Huang joined the business in 2014 there were approximately 192 active suppliers, of which approximately 47 remained active as at April 2022
35 Mr Huang described in detail the process undertaken by the applicant to determine whether it will procure products from a supplier. In cross-examination, he accepted that he has not been personally involved in the supplier identification and selection process. Rather, these tasks are performed by other employees of the business for whom he is ultimately responsible in his role as Chief Operating Officer. But it does not follow that he is unable to give evidence as to the steps taken within the business of the applicant and as to its usual or standard procedures. In broad outline those steps are:
(a) the Buyer Team reviews and analyses market data from a number of sources in order to identify potential new products that may be offered for sale;
(b) the Buyer Team will identify potential suppliers by first making contact with existing suppliers. If an existing supplier is not able to supply a particular product, the Buyer Team will take steps to identify a new supplier in China. Normally, that involves contacting suppliers by using an online business-to-business database that has been identified at trade fairs;
(c) in China, there are many, perhaps thousands, of potential suppliers for any one product. The quality, sophistication and cost of products varies widely;
(d) sometimes individual members of the Buyer Team will attend the Canton Trade Fair in order to personally inspect products and speak to the representatives of suppliers. The Canton Trade Fair is a large biannual manufacturing exhibition which hosts in excess of 20,000 exhibitors and is attended by hundreds of thousands of overseas buyers.
(e) the Buyer Team will formulate a short list of possible suppliers and then formulate a proposal for submission to the head of the Buyer Team;
(f) the head of the Buyer Team is responsible for making a decision as to whether a particular product will be procured;
(g) once a potential supplier has been sufficiently identified, samples of the products will be obtained and examined;
(h) New Aim undertakes a form of internal sampling and product testing, but often engages a third party to undertake the sampling and testing procedures;
(i) sometimes members of the Buyer Team will visit the factories of potential suppliers in China to inspect the manufacturing facilities and processes;
(j) the Buyer Team is responsible for negotiating the purchase order terms; and
(k) once a supplier has been identified for a particular product, the supplier details will be added to the internal procurement system maintained by the applicant and which is currently known as the New Aim Purchasing System.
36 The applicant monitors the sales data for its products. Market trends are identified. Popular products are promoted for sale. Less popular products are, over time, withdrawn from sale. Products with identified defects are reviewed and, depending upon the number or type of defects, the supplier may be requested to change the manufacturing or packaging system.
37 The identification of a reliable supplier for a product is important in the business of the applicant. Having identified a reliable supplier, the applicant will often increase the number of purchase orders from that supplier for various products, with some suppliers having been engaged for over five years.
38 When Mr Huang commenced employment, the product and supplier details of prospective products and suppliers were entered into an Excel spreadsheet and then provided to the Head of the Buyer Team for approval. These spreadsheets were saved in the applicant's internal share drive and were only accessible by members of the Category Team. The applicant later used an online buying and procurement software system known as Vtiger which contained all supplier details and wholesale pricing information.
39 Throughout 2017 and 2018, the applicant migrated Vtiger to a new program developed in-house known as the New Aim Purchasing System, the creation and distribution of which Mr Huang was involved in. This system acts as the centralised location that contains the entire list of suppliers and other information including the name, telephone number and bank details of the contact, as well as wholesale product information and purchase history.
40 The steps taken by the applicant to protect supplier information were listed by Mr Huang as follows (which evidence was not challenged or directly contradicted by the respondents):
(a) New Aim restricts access to supplier information in the New Aim Purchasing System to only those employees who require access in performing their role;
(b) Product packaging, labels and instruction manuals do not include supplier details, save for certain electrical products where disclosure is required by law;
(c) The applicant controls and limits the manner in which the Buyer Team communicates with suppliers, by strongly encouraging communications with suppliers to occur via the instant messaging application Enterprise QQ, as employee accounts are controlled by New Aim and deleted once an employee leaves the business. Enterprise QQ is an instant messaging application that is primarily used by members of the buying team in China. If unable to use Enterprise QQ, employees are advised to communicate via work email or DingTalk (an internal messaging service), as each platform is controlled by the applicant. Only if a supplier is not able or willing to use these platforms are New Aim employees allowed to use personal modes of communication such as WeChat;
(d) In approximately June 2020, the applicant implemented a Confidentiality/Intellectual Property Policy that is provided to all new employees forming a part of all employment contracts. Whether that Policy was provided to the respondents, in particular Mr Leung, is a disputed fact that I address later in these reasons.
41 Wholesale prices are agreed through extensive negotiation between the Buyer Team and suppliers, and when confirmed, are stored on the New Aim Purchasing System. Wholesale prices are commercially sensitive for the obvious reason that if a competitor were to become aware of a product's wholesale price, it could be utilised as a starting point for negotiations with a supplier, potentially affording competitors with a lower price of procurement and a lower retail price.
42 Mr Kang (Colin) Li is currently employed as the Category Manager within the Buyer Team at New Aim. He commenced employment with the applicant in September 2020, initially as a Category Co-ordinator within the bedding, home office and appliance subgroup of the Buyer Team. In this role, he was responsible for appraising existing product lines and locating new suppliers in China. Mr Li was then promoted to his current role of Category Manager of the Research and Development (R&D) sub-group of New Aim's Buyer Team, during which he managed the R&D team which included the development and sourcing of new products. Mr Li's job title was changed to Category Manager - Business Development in March 2022, though his responsibilities were essentially unchanged.
43 In his witness statement he set out in some detail the applicant's internal processes in order to procure new products and to identify new suppliers. In cross-examination he accepted that he had no direct knowledge of those matters prior to September 2020 and that his knowledge is limited to the product category bedding, office furniture and home appliances within the Buyer Team. However, I infer that the same or similar steps have been taken by the applicant since September 2020 for each product category within the various subgroups of the Buyer Team. On that basis, I accept his evidence which in summary was:
(a) The Buyer Team evaluates and analyses industry data to find gaps in the market for products expected to be attractive to Australian consumers. This analysis usually involves the review of competitors' websites, eBay data and New Aim's internal sales data, as well as independent online research and consideration of supplier recommendations;
(b) Employees in the Buyer Team are briefed on 'products of interest' and then proceed to identify potential suppliers;
(c) The Buyer Team creates a shortlist of at least 10 potential suppliers, narrowed on a range of factors including price, supplier background and factory location;
(d) Members of the Buyer Team then submit an initial request to each supplier on the shortlist to obtain a quotation and inquire about other details or information considered useful in deciding between prospective suppliers;
(e) The Buyer Team prepares a Value Chain Analysis report outlining financial data for each prospective supplier, including pricing and projected sales data, together with a detailed product proposal report with reasons for choosing the product line, an analysis of which product types would best appeal to the applicant's intended customers and a comparison of products from each supplier;
(f) When the sampling is undertaken, the Buyer Team sends the above reports and a proposed first purchase order to the Manager of the subgroup;
(g) The Buyer Team then negotiates payment terms with suppliers including a payment timeline. Once terms are agreed, the suppliers are added to the New Aim Purchasing System;
(h) Once having committed to an order, New Aim engages quality control from a third party to inspect the supplier's factory;
(i) Following the placement of the first order but prior to shipment to Australia, New Aim's QC team in China will review the supplier's factory and products; and
(j) Once the products arrive at New Aim's Melbourne warehouse, the products are advertised for sale across various online marketplaces.
44 Mr David Fixler is a partner of the firm Corrs, Chambers Westgarth (Corrs), the lawyers for the applicant. He gave uncontroversial evidence as to the purchase of various products from Broers and/or Sun Yee. It is not in dispute in this proceeding that Broers and/or Sun Yee offered for sale various products that were identical, or very similar, to these offered for sale by the applicant.
45 Ms Fangyun (Lindy) Chen is the Founder and Managing Director of ChinaDirect Sourcing, an Australian firm established by her in 2005 that assists clients in procuring products from suppliers in China. Ms Chen has also authored a book which examines the process of sourcing products from suppliers in China titled: Import from China: How to Make a Million and Not Get Burnt!, which was published in 2011. On account of her relevant industry experience and knowledge, Ms Chen was engaged as an expert witness for the applicant. Her evidence was objected to. I admitted her expert report dated 8 March 2022, after ruling on the objections to it. I have now concluded that I should reject each of the statements of fact and the expression of opinions as contained therein for the following reasons.
46 Her signed witness statement is dated 8 March 2022 and it attaches her report. In it she recites the purpose of her engagement is to act as an independent expert witness engaged by Corrs for the applicant in this proceeding. She stated that:
When I was retained, Corrs provided me with a copy of the Federal Court of Australia Expert Evidence Practice Note (GPN-EXPT), which includes the Harmonised Expert Witness Code of Conduct (Code). I confirm that I have read, understood and complied with the Code in providing expert assistance in the proceeding (including in making this witness statement), and agree to be bound by it. A copy of the Code is annexed to the retainer letter I received from Corrs on 21 February 2022, referred to below.
47 She attached a number of documents to her witness statement including a retainer letter from Corrs dated 21 February 2022, an instruction letter from the firm dated 7 March 2022 and her expert report dated 8 March 2022. What is remarkable about that timeline is that the letter of instruction directed Ms Chen to provide an overview of her business, with a focus upon the service that her business provides to clients and then to explain the practices "(if any) in the industry (including in particular, in the e-commerce sector) concerning the use and treatment of information pertaining to the identities and details of suppliers in China", all of which was able to be answered by Ms Chen in the form of her expert report the following day, comprising 16 pages and 60 paragraphs, not including attachments.
48 As might be expected, the apparent ability of Ms Chen to produce an expert opinion report so quickly was the subject of detailed cross-examination by counsel for the respondents. Initially, it was put directly to her that she did not draft "this entire report" herself within a space of 24 hours. Ms Chen answered, "I prepared within 24 hours" [sic]. She then disclosed that she had "a couple of conversations" with unidentified lawyers from Corrs between 21 February and 7 March 2022. She was pressed as to whether she had prepared and submitted earlier drafts of her report. She answered, "I think it was about two or three". She accepted that she sent drafts of her report to Corrs for comment. She accepted that she received comments from Corrs during a video conference. She denied receiving comments in writing, by email or otherwise. She was pressed as to whether the solicitors suggested to her that she should make changes to her draft report. To this simple question, she prevaricated and gave unsatisfactory and at times unresponsive answers. To this point her evidence was inconsistent, at times confusing and I began to doubt her independence. Eventually, she was asked the direct question: "who drafted the version of" her report as attached to her witness statement. She answered, "I started first" [sic]. Her evidence continued:
Yes? - And then we had a video conference, and then we went through some of the things, and the videoconference had, like, more information revealed. So, the second version - there are some other actual information in there.
Who put together the second version? - I think it's Sarah.
Who's Sarah? - Sarah is Corrs - the lawyer from the Corrs.
49 Counsel then pressed the witness with detailed questions in order to elicit information as to who was responsible for the drafting of which portions of the expert report. She specifically denied the proposition that "the drafting has generally been done by New Aim's solicitors rather than by you, hasn't it?" Her attention was drawn to certain paragraphs in her report which bear a remarkable similarity to paragraphs in the witness statement of Mr Huang. Once again it was directly put to her that she was not the author of all of her expert report. She failed to give satisfactory answers to those questions but eventually conceded that "but if you say every words of the sentence is exactly 100 per cent written by me, no" [sic]. Her demeanour was distinctly uncomfortable in giving that answer.
50 Eventually, Ms Chen conceded that she had received emails from Corrs, the effect of which was to suggest that she make changes to her draft report. Prudently, counsel for the respondents called for the production of all documents sent by Corrs to the witness, to the effect that alterations be made to, or commentary upon, her draft report. The evidence of Ms Chen was then adjourned so that she could attend at her office, obtain her computer and locate any other documents within the ambit of the call for production. Documents were produced, without objection as to legal professional privilege, and the cross-examination of Ms Chen resumed.
51 What then emerged from the evidence of Ms Chen is that on 22 February 2022, she sent her personal biography and some general information about her company to various lawyers at Corrs. On 25 February 2022, Sarah Catania, a lawyer in the employ of Corrs, advised Ms Chen by email that "we are progressing your witness statement and would like to arrange a call with you next week to discuss it further." Suitable dates were requested for a conference. On 6 March 2022, Ms Catania sent an email to Ms Chen. She copied it to various individuals within Corrs, including Mr Fixler. In part it reads:
We are in the process of finalising your statement and hope to have it to you soon. As discussed, we would appreciate it if you would send us examples of the following completed documents: supplier summary report, quote comparison report and landed cost analysis. We will redact the client and supplier names and any financial figures. If there is anything further you would like redacted, please let us know. As promised, we will not file anything without your clear approval.
52 Further emails were exchanged between Ms Catania and Ms Chen, which contained requests by the firm for further information and inquiry as to conference availability. Information was provided. There were more virtual meetings. On 7 March 2022 at 5:27 pm, Ms Catania emailed Ms Chen, which she copied to other lawyers within Corrs including Mr Fixler, in which she said:
Dear Lindy
Thank you for your time on the phone today.
We attach our letter of instructions to you in this matter.
We will send to you your draft statement shortly.
53 The attachment was the letter of instruction on 7 March 2022, signed by Mr Fixler. That letter, after briefly stating the background to the proceeding and under the heading "instructions" reads:
For the purposes of your expert evidence in this proceeding, you are instructed to:
• provide an overview of your business, ChinaDirect Sourcing and the services that your company provides; and explain, based on your experience and expertise, the process involved to identify reliable suppliers in China suitable for the Australian market, with a particular focus on the e-commerce sector;
• explain the practices (if any) in the industry (including, in particular, in the e-commerce sector) concerning the use and treatment of information pertaining to the identities and details of suppliers in China.
Please let us know if you require any further information from us to provide this opinion. If you have any queries, please let us know.
54 On 8 March 2022 at 11:40 am, Ms Catania emailed Ms Chen, which she again copied to other lawyers within the firm, including Mr Fixler, and stated that:
Dear Lindy
Further to our call this morning, we attach the draft witness statement and expert report for your review. The annexures and attachments may be located at this link. Please let us know if you have any queries.
Kind regards
Sarah
55 The attached witness statement and expert report are not materially different from the versions that were finalised, signed and dated, filed in this proceeding and delivered as the independent expert opinion of Ms Chen, though the date of delivery is unclear.
56 On 11 April 2022, the solicitor for the respondents emailed correspondence to Ms Catania at Corrs, referenced the expert report of Ms Chen and stated:
Please provide, by no later than 4 pm on Wednesday, 13 April 2022, copies of the following documents:
(a) All documents recording any communications between your firm and Ms Chen;
(b) All documents recording any communications between your client, including their employees and Ms Chen; and
All drafts of the expert report.
57 Mr Fixler responded to that request by email on 12 April 2022. Inter alia he said:
There is no legitimate basis for such a request. Insofar as your clients seek production of correspondence with Ms Chen, our client maintains its privilege over that correspondence, except to the extent that it discloses the instructions given to Ms Chen (and those documents have already been produced at Annexure FC-1 of Ms Chen's witness statement dated 8 March 2022). The filing of Ms Chen's witness statement does not itself lead to a waiver…
58 The solicitor for the respondents did not accept that. A detailed and reasoned request for the production of the documents was sent by email on 13 April 2022, although the attached letter is wrongly dated 11 April 2022. The requested documents were not produced. On 16 April 2022, Mr Fixler sent correspondence by email to the solicitor for the respondents. Amongst other things he said:
As we previously communicated, all of the instructions given to Ms Chen have already been provided (as Annexure FC-1 to Ms Chen's witness statement). For completeness, we also advise that there are no communications between New Aim and Ms Chen. To the extent that your client presses for drafts of Ms Chen's report and any other communications between Corrs and Ms Chen record instructions given to Ms Chen, our client maintains that this is neither necessary nor appropriate. In particular, as discussed further below, these communications and documents are privileged, and there has been no waiver of that privilege.
59 The respondent's solicitor did not respond to that email.
60 I return to the cross-examination of Ms Chen about this chronology of events. She was questioned as to which portions of her expert report were drafted by her and which portions were drafted by Corrs. She answered, "I don't know how to define that part". She agreed that her report was "a collaboration" between her and the lawyers from Corrs. She was questioned further about other aspects of the drafting of her report, which I do not find it necessary to address in these reasons, save for her evidence about the drafting of paragraphs [58] - [60]. These paragraphs appear at the end of her report and state various opinions to the effect that, in the experience of Ms Chen, a list of suppliers in China who are reliable and produce a range of high-quality goods suitable for the Australian market "is almost always considered to be and is treated… as confidential and a very valuable asset of the business", that her clients "typically request that the identity and details of the supplier are not disclosed" and that "it would be extremely difficult to identify the supplier of a product manufactured in China if the details were not disclosed on the product." Ms Chen accepted that paragraph [58] was drafted by Corrs but reflected her opinion. However, it is also the fact that the second sentence of that paragraph, as counsel for the respondents correctly observed, bears a "striking similarity" to paragraph [41] of the witness statement of Mr Huang dated 16 March 2022. I infer that those sentences were drafted by the same person, in this case, one or more lawyers from Corrs. She further accepted that the drafting selectively reproduced portions of her book, favourable to the applicant's case.
61 In some circumstances, the fact that an expert witness may agree with a form of words for the expression of the expert's opinion which are put to the expert in an admissible form, may not detract from the independence of the expert and the reliability of the opinion expressed. That observation is consistent with the reasoning of Lindgren J in Harrington-Smith on Behalf of the Wongatha People v Western Australia (No 7) (2003) 13 FCR 424; [2003] FCA 893 at [18]- [19] where he said:
Unfortunately, in the case of many of the experts' reports, little or no attempt seems to have been made to address in a systematic way the requirements for the admissibility of evidence of expert opinion. Counsel protested that, in order to ensure that the requirements of admissibility are met, lawyers would have to become involved in the writing of the reports of expert witnesses. In the same vein, counsel said, in supporting the admission of certain parts of a report, that they were written in the way in which those qualified in the particular discipline are accustomed to write.
Lawyers should be involved in the writing of reports by experts: not, of course, in relation to the substance of the reports (in particular, in arriving at the opinions to be expressed); but in relation to their form, in order to ensure that the legal tests of admissibility are addressed. In the same vein, it is not the law that admissibility is attracted by nothing more than the writing of a report in accordance with the conventions of an expert's particular field of scholarship. So long as the Court, in hearing and determining applications such as the present one, is bound by the rules of evidence, as the Parliament has stipulated in subs 82(1) of the NT Act, the requirements of s 79 (and of s 56 as to relevance) of the Evidence Act are determinative in relation to the admissibility of expert opinion evidence.
(Original emphasis.)
62 That must be read with an understanding that his Honour was dealing with, at case management level, a large number of objections as to the content of various expert reports to be relied upon as opinion evidence upon the trial of the proceeding. It is, necessarily, a general observation. Much depends upon the particular circumstances. And one should not overlook the further reasoning of his Honour at [27]:
Unfortunately, however, in the case of many of the present reports, it is difficult to avoid the impression that no attempt at all has been made to address the criteria of admissibility of expert opinion evidence. The difficulty of my task is increased as a result. My impression is that in some cases, beyond the writing of an initial letter of instructions to the expert, lawyers have left the task of writing the reports entirely to the expert, even though he or she cannot reasonably be expected to understand the applicable evidentiary requirements. Such a course may have been followed because of a commendable desire to avoid any possibility of suggestion of improper influence on the author. But I suggest that the distinction between permissible guidance as to form and as to the requirements of s 56 and 79 of the Evidence Act, on the one hand, and impermissible influence as to the content of a report on the other hand, is not too difficult to observe. It does not serve the interests of anyone, including those of the expert witness, to deny him or her the benefit of guidance of the kind mentioned.
63 What occurred in this case went well beyond permissible guidance of that character. Counsel for the respondents invites me to reject the entirety of the expert report of Ms Chen, or alternatively to place no weight upon it, as falling within that category of case identified by Lord Wilberforce in Whitehouse v Jordan [1981] 1 WLR 246 at 256 (Whitehouse) where in his speech he said:
One final word. I have to say I feel some concern as to the manner in which part of the expert evidence called for the plaintiff came to be organised. This matter was discussed in the Court of Appeal and commented upon by Lord Denning MR [1980] 1 All ER 650, 655. While some degree of consultation between experts and legal advisers is entirely proper, it is necessary that expert evidence presented to the court should be, and should be seen to be, the independent product of the expert, uninfluenced as to form or content by the exigencies of litigation. To the extent that it is not, the evidence is likely to be not only incorrect but self -defeating.
64 In the Court of Appeal, Lord Denning MR was strident in his criticism of the apparent practice of counsel, when settling the document, to suggest that portions of it be deleted or that additions be inserted [1980] 1 All ER at 655.
65 That approach may not be consistent with authority in Australia. Conversely, it may be that there is no direct inconsistency between the English and the Australian approach once it is understood that "everything depends on the circumstances": Phosphate Co-operative Co of Aust Pty Ltd [1989] VR 665 at 683, Brooking J who continued:
The guiding principle must be that care should be taken to avoid any communication which may undermine, or appear to undermine, the independence of the expert. What happened here was quite unsatisfactory.
66 In that case, an ostensibly independent expert report was provided to shareholders for their consideration and approval of a proposed scheme of arrangement which opined that the scheme was fair and reasonable. The accountants retained by the company to express the opinion on that question submitted a number of draft reports which were discussed with representatives of the company and its lawyers. That process led to a substantial rewriting of the opinion. Unsurprisingly, his Honour refused to grant approval for the proposed scheme of arrangement, for the reason that the report was not a genuine and independent expression of opinion.
67 Callinan J in Boland v Yates Property Corporation Pty Ltd (1999) 74 ALJR 209 considered this issue at [276] - [279] and stated that Lord Wilberforce had gone "too far" in Whitehouse. It is useful to reproduce some of his Honour's reasoning at [279]:
For the legal advisors to make suggestions is a quite different matter from seeking to have an expert witness give an opinion which is influenced by the exigencies of litigation or is not an honest opinion that he or she holds or is prepared to adopt. I do not doubt that counsel and solicitors have a proper role to perform in advising or suggesting, not only which legal principles apply, but also that a different form of expression might appropriately or more accurately state the propositions that the expert would advance, and which particular method of valuation might be more likely to appeal to a tribunal or court, so long as no attempt is made to invite the expert to distort or misstate facts or give other than honest opinions. However it is the valuer who has to give the evidence and who must make the final decision as to the form that his or her valuation will take. It will be the valuer and not the legal advisors who is under oath in the witness box and bound to state his or her opinions honestly and the facts accurately. The lawyers are not a valuer's or indeed any experts' keepers.
68 The learned author of Cross on Evidence (Electronic Version, LexisNexis, current to March 2022) at [29080] states that:
What is the role of the legal practitioner in preparing the expert's report? At least from the point of view of ethics and weight, since an independent expert is expected to be non-partisan, the consultation with the party's legal advisers which may be proffered to ensure that the report is directed to the issues before the court, must not be permitted to distort the substance of the witness's opinion so that it loses its essential character as an independent report unaffected as to form or content by the exigencies of litigation… It is legitimate for legal practitioners to identify the real issues for the expert, to indicate when the report fails to direct itself to the real issues, to point out the obscurities and gaps in the reasoning, to indicate that the report fails to distinguish between the assumed facts and the opinion which is supposed to be based on them, and to indicate that the report does not explain how the opinion is substantially based on the expert's specialised knowledge.
69 To similar effect, see Freckelton and Selby, Expert Evidence Law, Practice and Procedure (6th ed, Thomson Reuters) at [5.0.150]. Mr Hugh Stowe, in an article published in 2018 observes that "the better view is that there is no ethical impropriety under the present rules in the barrister preparing the first draft (in conference or alone), based on instructions received from the expert. However, the considerations of strategic prudence referred to above strongly dictates that the expert should typically prepare the first draft": Preparing expert witnesses - a (continuing) search for ethical boundaries [2018] Bar News 72 at 77-78. For the contrary view see Ipp J, Lawyers Duties To The Court (1998) 114 LQR 63 at 92. Whilst there may not be an ethical difficulty if the lawyer drafts the report based on instructions from the expert, as this case demonstrates proceeding in that way poses the serious risk of compromising the independence of the expert and of undermining the value of the opinion. Further, this is clearly a case which in my opinion substantially departs from the proper role of lawyers who engage independent experts in legal proceedings.
70 There are many difficulties with the expert report of Ms Chen, which individually and cumulatively lead me to the conclusion that I should reject it in its entirety. I am left in a state of uncertainty as to who was responsible for the drafting of which portions of her report. It would appear that most of the report was, at least initially, the product of drafting by the lawyers for the applicant, albeit in reliance upon some material of a non-specific nature that Ms Chen provided to the lawyers. The fact that Ms Chen adopted the drafting of others as her opinion does not address the more fundamental issue that her engagement obliged her to act as an independent expert witness conformably with the requirements of the Expert Evidence Practice Note and the Harmonised Expert Witness Code of Conduct. Clause 3.2 of the Practice Note advises that:
A party or legal representative should be cautious not to have inappropriate communications when retaining or instructing an independent expert, or assisting an independent expert in the preparation of his or her evidence.
71 That statement of good practice was not complied with in this case. It may be perfectly appropriate, such as in cases where an expert is unfamiliar with the form and content requirements for an expert opinion report, for that document to be settled in an admissible form by someone else, but then in my opinion, only if that fact is disclosed in the report. In this case, that fact was not only withheld but was only ascertained during the course of cross-examination of Ms Chen, which in my opinion, was grossly unsatisfactory.
72 The Code of Conduct at clause 2 states the obvious proposition that an expert witness "is not an advocate for a party and has a paramount duty, overriding any duty to the party to the proceedings or other person retaining the expert witness, to assist the Court impartially on matters relevant to the area of expertise of the witness." In this case, that requirement of impartiality was substantially undermined by the failure to disclose the methodology of preparation of the expert report.
73 In the last paragraph of the signed witness statement, Ms Chen declared that she had "made all the enquiries which I believe are desirable and appropriate and no matters of significance which I regard as relevant here, to my knowledge, have been withheld from the Court." I cannot accept that Ms Chen failed to appreciate that the fact that her report was drafted, not by her but by the lawyers for the applicant, was not a matter of significance. It plainly was.
74 Regrettably, I also find that the conduct engaged in preparing and delivering the report of Ms Chen was misleading. The letter of instruction of 7 March 2022 conveys the representation that Ms Chen was engaged to prospectively consider each of the two questions the subject of her instruction. Contrary to that representation, a draft of her expert report had been prepared by Corrs no later than 25 February 2022. It was wrong in my opinion to state in the letter of 7 March 2022 that Ms Chen was instructed to prepare a report in response to the two questions posed in that letter, when the author was plainly aware not only of what the answers would be, but also, as to the form of the opinion and the fact that its expression was the product of drafting by Corrs. The letter of 7 March 2022 conveys the false representation that Ms Chen, as the independent expert, would upon receipt of the instruction set about the task of preparing her report. The failure to disclose those facts to the solicitor for the respondents and ultimately to the Court is most concerning, as it strikes at the very heart of the paramount and overriding duty that an independent expert has to assist the court impartially on matters relevant to the area of expertise of the witness, as stated at clause 2 of the Code of Conduct.
75 The solicitor for the respondents made two requests for the provision of "all documents regarding any communications between your firm and Ms Chen". Each request was denied, with the express representation that all documents evidencing or disclosing instructions given by Corrs to Ms Chen "have already been produced" as attachments to her witness statement of 8 March 2022. That was false in that the email correspondence that was exchanged between Corrs and Ms Chen commencing on 22 February 2022 was concerned with instructions as to who would draft the report and what it would be based upon.
76 What occurred in this case went far beyond the permissible scope of involvement of lawyers who retain an independent expert in order to give evidence in a proceeding. I reject the submission of counsel for the applicant that I should accept Ms Chen as an independent expert witness and that "the process by which her evidence was prepared is unremarkable." For the reasons I have given, it most certainly was not. Even if in some circumstances it is proper for lawyers to draft an independent expert witness statement for consideration by the putative expert, that fact must be disclosed in the expert report conformably with the obligations that the expert assumes in accordance with the Expert Evidence Practice Note of this Court and the Harmonised Expert Witness Code of Conduct. And then, all correspondence relating to the manner of preparation of the report should be disclosed and, to the extent that oral advice is conveyed to the expert, the substance should be documented and disclosed. What occurred in this case should not be repeated.
77 In the result, I cannot be satisfied that the opinions expressed in the report by Ms Chen truly represent her honest and independent opinions and that no matters of significance have been withheld. I reject all opinions and other factual material as set out in her report of 8 March 2022.
78 That leads to another matter. I raised with counsel during closing submissions whether, if I were to reject the opinion evidence as set out in the report, I should also reject the entirety of the evidence given by Ms Chen when cross-examined. I am not persuaded by the submission then put to me, that I should not and that it is open to me to make findings of fact based on her oral evidence. I have no confidence in the ability of Ms Chen to give credible, untainted and independent evidence and it would be quite wrong for me, having rejected the entirety of her written opinion evidence, to then proceed on the basis that I may, selectively, make findings of fact in accordance with her oral evidence. I cannot have confidence that her oral evidence was untainted by the factual material and the opinions expressed in her written report and the manner of its preparation I will not make any finding of fact based on any of her evidence.
