Background
9 I summarise below the background to the business relationship between LKPL, Mr Lipman and Mr Karas, and the genesis of the dispute between the parties. In so doing, I am not making findings of fact, but recording what is largely common ground that exists between them.
10 The background facts of this matter are not generally in dispute. Rather, it is the characterisation of the business relationship between the parties and the significance and effect of that business relationship on the issue of confidentiality asserted over documents/information, primarily emails.
11 Both Mr Lipman and Mr Karas are qualified legal practitioners. In 2004, both were equity partners in the legal firm Fisher Jeffries. In or about August 2004, Mr Lipman and Mr Karas established the legal firm LKPL. Apart from Mr Lipman and Mr Karas, a further nine employees, who had previously been with both Mr Lipman and Mr Karas at Fisher Jeffries, worked at LKPL.
12 Between 2005 - 2009, Mr Karas spent a considerable amount of his time in Hong Kong working on a substantial litigation matter.
13 In 2008, Mr Lipman and Mr Karas decided to establish a "Lipman Karas" practice in Hong Kong. As part of investigating how they might establish such a practice, Mr Lipman and Mr Karas sought advice from a Hong Kong firm of solicitors, Tanner De Witt. That advice, in summary, was that LKPL could not immediately establish a legal firm in Hong Kong advising on Hong Kong law using the name Lipman Karas. That was because Mr Lipman was not admitted as a solicitor in Hong Kong. LKPL could, however, register as a foreign law firm in Hong Kong, using the name "Lipman Karas" and advising on foreign law.
14 The advice from Tanner De Witt continued that after LKPL had practised as a foreign law firm in Hong Kong for three years, a firm practising Hong Kong law under the name "Lipman Karas", could practice in Hong Kong notwithstanding Mr Lipman was not qualified as a solicitor to practice in Hong Kong.
15 In October 2008, Mr Karas was admitted to practice in Hong Kong as a solicitor.
16 The strategy adopted by Mr Lipman and Mr Karas was that over the three-year period, Mr Karas would establish a registered Hong Kong law firm under the name "Karas Lawyers" with Mr Karas being the sole proprietor of that firm. Whilst Mr Karas was practising under the name "Karas Lawyers", Lipman Karas would establish itself as a foreign law firm practising foreign law in Hong Kong with Mr Tim Kentish (Mr Kentish) as the proprietor of that firm. Mr Kentish was to act as LKPL's agent in Hong Kong.
17 On 17 February 2010, the foreign law firm Lipman Karas, as agent for LKPL, and Karas Lawyers entered into an agreement known as an "association agreement". The association agreement is annexed to the first Karas affidavit at pp 18-23 of annexure JK-1: First Karas affidavit at [19]; Lipman affidavit at [41]. The association agreement recorded, amongst other things, that:
Recital C - On 6 November 2009 the Law Society of Hong Kong registered an Association between Lipman Karas and Karas Lawyers in accordance with section 39C of the Legal Practitioners Ordinance.
Clause 2.1 - Premises
(a) Lipman Karas will permit Karas Lawyers to share and use with Lipman Karas the premises located at 1702, Tower 1, Admiralty Centre, 18 Harcourt Road, Hong Kong (Premises).
(b) Lipman Karas will be responsible for all costs associated with the Premises and will maintain contents and public liability insurance in respect of the Premises.
Clause 2.3 - IT
(a) Lipman Karas will permit Karas Lawyers to share and use with Lipman Karas the information technology infrastructure, including personal computers, servers, printers, photocopiers, fax machines, videoconferencing equipment, mobile telephones and landline telephones (the IT infrastructure).
(b) Lipman Karas will be responsible for all costs associated with the IT infrastructure (including consumables) and will maintain the IT infrastructure to a reasonable standard.
Clause 2.4 - Staff
(a) Lipman Karas and Karas Lawyers will share the resources of staff employed by the respective firms.
(b) Each firm will be responsible for the salaries and related on-costs of its respective staff.
Clause 3.1 - Premises Fee
(a) In consideration of the use of the Premises, Karas Lawyers will pay Lipman Karas an annual fee (Premises Fee) calculated in accordance with the following formula: …
18 Having spent three years practising as a foreign law firm in Hong Kong, in late 2012 Lipman Karas ceased to practise as a foreign law firm. Mr Karas changed the name of Karas Lawyers to Lipman Karas and began trading as "Lipman Karas" in Hong Kong (LKHK).
19 There is a difference in emphasis between Mr Lipman and Mr Karas about how the LKPL and LKHK relationship worked. Mr Lipman refers to a letter from Mr Karas to the Law Society of Hong Kong dated 8 October 2012: Lipman affidavit at [44]; first Karas affidavit at [20]; annexure JK-1 pp 24-34 in which Mr Karas states, amongst other things, that:
It is proposed that the offices of Lipman Karas will, for the purposes of the distribution of profits among principals, operate as a single economic entity.
and that in a letter from Mr Lipman as a principal of LKPL to the Law Society of Hong Kong enclosed with Mr Karas' letter dated 8 October 2012, Mr Lipman states that from 10 December 2012 the renamed Karas Lawyers will act as the firm's Hong Kong branch.
20 In contrast, Mr Karas deposes that there was always a relationship of debtor and creditor between LKPL and LKHK: First Karas affidavit at [24]-[25]. Mr Lipman disputes that characterisation: Lipman affidavit at [113].
21 After the change in name to LKHK in December 2012, Mr Lipman described how the two firms worked together: Lipman affidavit at [48]. Mr Karas described it by focusing on what he described as the "debtor/creditor" relationship with LKPL and highlighted the profit sharing and drawings arrangement.
22 Thereafter, the relationship continued. Both Mr Lipman and Mr Karas highlighted in their respective affidavits features of the relationship which they say support their respective cases. In the case of Mr Lipman, broadly speaking, it is that Mr Karas conducted LKHK as agent for LKPL, and in the case of Mr Karas, that he operated LKHK as a sole owner.
23 In passing, I note that in 2012, what I will describe in neutral terms as a third Lipman Karas entity, had commenced practice in London as LKLLP. There were three owners of that entity with Lipman Karas UK Ltd owning 50% of the business. The two 50% shareholders in Lipman Karas UK Ltd were Mr Lipman and Mr Karas: first Karas affidavit at [21].
24 By early 2019, the relationship between Mr Lipman and Mr Karas had deteriorated. There are many reasons why that seems to be the case and it is not necessary that I go into them at this stage.
25 By December 2020, Mr Lipman and Mr Karas had decided to go their own ways and needed to separate their respective interests.
26 After Mr Lipman and Mr Karas decided to separate their business interests, negotiations commenced between the two of them with the parties executing a facilitation agreement in which a third party was appointed to assist in the resolution of the dispute: Lipman affidavit at [83], annexure SJL-35.
27 With the assistance of that third party, agreement was reached and on 25 May 2021 Mr Lipman, Mr Karas, Lipman Karas Pty Ltd, J&A Karas Pty Ltd, and Lipman Family Pty Ltd executed a separation agreement (separation agreement). The effective date of the separation agreement was 31 May 2021: First Karas affidavit, annexure JK-1 pp 138-176; Lipman affidavit, annexure SJL-2.
28 In summary, by the separation agreement, Mr Karas kept LKHK and Mr Lipman took over LKPL. The name of the firm Lipman Karas in Hong Kong was changed to Karas LLP and there were mutual releases.
29 Clause 5 of the separation agreement deals with transitional arrangements. Clause 5.2 concerns the ongoing provision of legal services by LKPL to LKHK in relation to various LKHK "Projects" and provides:
5.2 From the Effective Date until the completion of the LKHK Projects, Jason and LKHK will (a) instruct LKPL and LKPL will provide legal services to LKHK in relation to [various clients] and (b) continue to utilise LKPL lawyers presently engaged on the LKHK Projects, at the LKPL rates that are applicable for each of those LKHK Projects as at the Effective Date, to be invoiced monthly by LKPL to LKHK and paid by LKHK to LKPL when LKHK receives payment from its client, subject to the instructions of the respective clients for whom LKHK is engaged to provide legal services in respect of the LKHK Projects. Those legal services are anticipated (but not guaranteed) to generate [fees] for LKPL.
(Square brackets provided)
30 Clauses 5.7, 5.8, 5.10 and 5.11 concern information technology:
5.7 As soon as practicable after the Effective Date, Skip and LKPL will transfer all IT, accounting, document management, legal database and other business support information and systems in respect of LKHK, LKHK personnel, LKHK matters and LKHK clients to such systems as designated by Jason and LKHK, with all such transfers to be completed by no later than 31 October 2021 or for such longer period as may be mutually agreed in writing.
5.8. Skip and LKPL will provide to Jason and LKHK ongoing access to the information referred to in clause 5.7 above until the transfer has been completed as certified by the Chief Technology Officer of LKPL to Jason and LKHK.
5.9 …
5.10 Jason and LKHK must continue to maintain IT security in accordance with LKPL security and IT policies, until the transfers set out in clause 5.7 have been completed and the ongoing access set out in clause 5.8 has been terminated.
5.11 If required, third party access to LKPL IT systems and network must be certified by the Chief Technology Officer of LKPL, with such certification not to be unreasonably withheld.
31 Prior to this time, all the information technology, including emails generated by user accounts at LKPL and LKHK, had gone through a common server operated by LKPL.
32 Mr Karas acknowledges this in the first Karas affidavit at [86], [87] where he says:
86 LKPL provided IT support to LKHK, including an email server for my email account jkaras@lipmankaras.com (prior to July 2021) and storage of electronic documents on a server (prior to October 2021).
87 I accessed my email account jkaras@lipmankaras.com from two laptop computers on which I also stored documents.
33 Mr Lipman deposes that there was an Information Technology Security and Data Protection Policy which applied to "everyone at Lipman Karas": Lipman affidavit at [10.2]. Mr Lipman annexes that policy at annexure SJL-3 and refers to clause 24 which is under the heading "EMAIL USE":
24. All messages that you send, receive or store are the property of LK. All messages sent internally, externally and received are stored permanently. Email messages stored on the LK system should not be considered private and management may have cause to monitor your use of the computer system or internet usage, or access your individual email account. While these occurrences are rare, this should be borne in mind.
34 Mr Karas deposes that the only email policy which he is aware is that titled "Lipman Karas - IT Security and Data Protection Policy" dated 17 September 2019: First Karas affidavit at [99], annexure JK-1, pp 551-556. He deposes that the policy appears to be directed to employees of LKPL and asserts he has never been bound by the policy. He continues that he has never been an employee of LKPL, LKHK or LKLLP and nor could he (nor any employee of LKHK) be bound by a policy by which legally privileged information confidential to his Hong Kong clients could "belong" to LKPL.
