[84] For these reasons, I am satisfied that the restraints in cl 6.1(a)(i) and (iii) go no further than are reasonably necessary to protect Genesys' legitimate business interests against competition from Mr Miles for the remainder of the restraint period. I hold that the restraint clauses are valid.
29 Mr Neil submitted that, in relation to the restraint against soliciting or dealing with Member Firms, the primary judge did not identify the legitimate interest of Genesys which could be protected, or address the question of what extent of protection was justified.
30 He submitted that the claim for protection must be based on some advantage that can properly be regarded as the employer's property, and that it would be unjust to allow the employee to appropriate (Stenhouse Ltd v Phillips [1974] AC 391 at 400); and client connection based on the employee's personal qualities does not belong to the employer (J D Heydon The Restraint of Trade Doctrine, 3rd ed, (2008) at 121,133; Herbert Morris Limited v Saxelby [1916] 1 AC 688 at 714). The restraint could be justified only if Genesys had proved its employment of Mr Miles caused him to acquire inducing influence over the Member Firms, and caused the Member Firms to regard him as the personification of its business (Australian Retail Wholesalers v Stafford [2007] NSWSC 572; (2007) ATPR 42-168 at [55]-[60]; John Fairfax Publications v Birt [2006] NSWSC 995 at [30]). The only relevant findings made by the primary judge (at [77] and [80]) did not address these issues.
31 As regards the period of restraint, Mr Neil submitted that restraint could only be justified for such period as was reasonably necessary for Genesys to put someone else in Mr Miles place and for that employee to have a reasonable opportunity to demonstrate his effectiveness to Member Firms (DalySmith Corporation (Australia) Pty Limited v Cray Personnel Pty Limited (Supreme Court of New South Wales, Young J, 14 April 1997, unreported) at 13). There was no consideration of this matter by the primary judge.
32 As regards the period of the restraint on the basis of confidential information, Mr Neil submitted there was no basis for a conclusion that there was a risk of detriment to Genesys after 14 months (and for the remainder of the 30 months) from use of confidential information such as to justify a restraint that effectively precluded Mr Miles from performing senior executive roles in the planning industry.
33 Mr Neil also submitted that the primary judge erred in not having regard to the length of restraint imposed by Genesys on employees in positions similar to Mr Miles, and in rejecting evidence in relation to that matter. Evidence is admissible as to what is usual in similar circumstances (Sir W C Leng & Co v Andrews [1909] 1 Ch 763 at 770; Mason v Provident Clothing and Supply Co Limited [1913] AC 724 at 732-3) and in the business of the particular employer (Portal Software v Bodsworth [2005] NSWSC 1179 at [79]; Koops Martin v Dean Reeves [2006] NSWSC 449 at [56]-[59]).
34 Mr Meagher submitted that some of the statements relied on by Mr Neil were too restrictive, and he referred to the judgment of Brereton J in Koops at [26], [29]-[34], [80] and [83]-[84].
35 Mr Meagher submitted that Mr Miles was intimately involved, on behalf of Genesys or its predecessor, with the principals of Member Firms for 20 years, and so had influence that had been acquired in the service of or for the benefit of Genesys. Further, he had participated extensively in the preparation of a business plan for Genesys for the next five years. He had legal advice in entering the relevant Deed, and he and Genesys were in the best position to judge what was reasonable to protect the legitimate interest of Genesys. The restraint was also not unreasonable in that it allowed for him to work for Brown Bulley.
36 In my opinion, there is no precise rule on the basis of which the period for which an employer is legitimately entitled to protection can be determined. I would not endorse the statement by Young J in DalySmith at 13 that "a restraint that enures after the time taken for a reasonably competent new employee to master the job and be able to demonstrate to the customer that he or she is effective and efficient will be too long".
37 I would respectfully adopt the general statement of principle by the Privy Council in Stenhouse at 400:
The accepted proposition that an employer is not entitled to protection from mere competition by a former employee means that the employee is entitled to use to the full any personal skill or experience even if this has been acquired in the service of his employer: it is this freedom to use to the full a man's improving ability and talents which lies at the root of the policy of the law regarding this type of restraint. Leaving aside the case of misuse of trade secrets or confidential information (which is separately dealt with by clause 3 of the agreement and which does not arise here), the employer's claim for protection must be based upon the identification of some advantage or asset inherent in the business which can properly be regarded as, in a general sense, his property, and which it would be unjust to allow the employee to appropriate for his own purposes, even though he, the employee may have contributed to its creation. For while it may be true that an employee is entitled - and is to be encouraged - to build up his own qualities of skill and experience, it is equally his duty to develop and improve his employer's business for the benefit of his employer. These two obligations interlock during his employment: after its termination they diverge and mark the boundary between what the employee may take with him and what he may legitimately be asked to leave behind to his employers.
38 Where, as in this case, a senior officer of an employer company has on behalf of that employer fostered close and productive relationships with customers, having dealings on behalf of the employer with principals of those customers and being to them the human face of the employer, there may be a relationship of the employee with the customers that "can properly be regarded as, in a general sense, [the employer's] property". Of course, insofar as the employee's own qualities of skill and experience recommend him or her to the customer, the employee should be free to employ that, but subject to considerations of the unfairness of the employee being able to exploit relationships that are properly regarded as the employer's property.
39 In my opinion, that approach may, in cases such as the present, justify a restraint longer than that contemplated by Young J in DalySmith.
40 I accept Mr Neil's submission that the length of restraints imposed on employees in similar positions has some relevance and should not have been excluded, just as the restraint of 13 weeks in Mr Mile's own earlier contract has some relevance. However, in my opinion the relevance is not greatly significant in this case, where the relevant restraint was freely agreed upon in negotiations in which Mr Miles was by no means disadvantaged and in which he had legal advice.
41 In my opinion, the relationship shown to exist between Mr Miles and the Member Firms and their principals could properly be regarded as being, to a substantial extent, the property of Genesys, as well as being something supported by Mr Miles' own qualities of skill and experience. A fair and proper balance between these competing considerations is a matter of judgment, as to which reasonable minds could differ. Having regard to the length and quality of the connection maintained on behalf of Genesys, a judgment that a restraint of 30 months was appropriate to protect the employer's legitimate interests would not in my opinion be an unreasonable one.
42 As put by Mr Meagher, the persons in the best position to make that judgment were Mr Miles and Genesys, and that judgment was expressed in an agreement reached in the way mentioned. In my opinion, this is sufficient to justify the restraint protective of the customer connection.
43 In relation to the confidential information restraints, the position is less clear. One justification for restraints of the kind used in this case and in Kone is the difficulty of protecting confidential information in any way other than by precluding types of employment. However, provisions of that kind are extremely restrictive when those types of employment are broadly co-extensive with the employee's area of expertise, as in this case. This is to some extent ameliorated in this case by the qualification permitting Mr Miles to engage in something like the area of his expertise in the particular way contemplated at the time, namely in any Member Firm that he buys into; and of course the reasonableness of the restraint has to be judged at the time of entry into the agreement: Woolworths Limited v Olson [2004] NSWCA 372 at [40].
44 However, an important part of the confidential information sought to be protected in this case was information concerning Member Firms which could assist Mr Miles to target Member Firms and to formulate offers attractive to them; and Genesys has some protection against misuse of that confidential information by the covenant against soliciting or dealing with Member Firms. That protection is not absolute, and would no doubt be assisted by a prohibition on working in areas where there is the possibility of Mr Miles covertly trying to deal with Member Firms, or doing so indirectly (as pointed out by Handley AJA); but in my opinion, the blanket restraint on Mr Miles working in the area of his expertise (other than with Brown Bulley or some other Member Firm) for the period between 14 months and 30 months after termination of his employment goes beyond what is reasonably necessary to protect the legitimate interests of Genesys in relation to confidential information concerning Member Firms, when Mr Miles is bound by his agreement during this period not to deal at all with Member Firms.
45 As regards the remainder of the confidential information, concerning Mr Miles' knowledge of the business plan of Genesys, in circumstances where no documents were taken it is unlikely that such information as Mr Miles could recall after 14 months would be sufficiently detailed or currently relevant to have the potential to be used in any effective way to the detriment of Genesys; and in my opinion, in this respect also, a blanket restraint on Mr Miles working in the area of his expertise (other than with Brown Bulley or some other Member Firm) for the period from 14 to 30 months after termination of his employment goes beyond what is reasonably necessary to protect the legitimate interests of Genesys.
46 The primary judge did not explicitly address these questions; and in my opinion it is appropriate for this Court to give effect to its own views on them.
47 For those reasons, I would uphold the appeal to the extent that it relates to the restraint based on confidential information.
