50 Whether a covenant in restraint of trade is no more than is reasonably necessary for the legitimate protection of the covenantee's interests is to be tested as at the time that the covenant was entered into and by reference to what the covenant requires or entitles the parties to do rather than by reference to what they intend to do or have actually done: Curro v Beyond Productions Pty Ltd at 344C.
51 A factor to which the Court has regard is whether the parties have, as a result of negotiation on equal terms, freely made a bargain in which the particular restraint has been sought by one and given by the other. It is often said that in such a case the parties must be taken to know what is in their interests and what is reasonable: see e.g. per Lord Pearce in Esso Petroleum Co Ltd v Harper's Garage (Stourport) Ltd at 323. But although the Court will give considerable weight to the fact that the parties have negotiated and agreed upon the covenant, it cannot regard that fact as conclusive: see e.g. Queensland Co-operative Milling Association v Pamag Pty Ltd (1973) 133 CLR 260, at 268, per Walsh J. In this regard, the position of the covenantee is not improved even if, as here, the contract contains an express acknowledgment by the covenantor that the restraint is reasonable: Sale of Practice Contract, Clause 10.1. This must be so because the ultimate consideration for the Court is whether public policy has been served in striking down restraints of trade which go further than is reasonably necessary to protect the legitimate interests of those seeking to benefit from them or which are otherwise contrary to the public interest.
52 Accordingly, while the Court gives weight to the fact that the parties have agreed upon the terms of a restraint, the party seeking to enforce the restraint still bears the onus of showing, by sufficiently persuasive evidence, that the protection of the covenant is no greater than is reasonably necessary between the parties. In discharging that onus, that party must do more than merely point to the existence of a bargain; it must justify the restraint by reference to the circumstances of the particular case.
53 For example, where a restraint of trade covenant is obtained to protect the goodwill of a medical practice it will be relevant to know what is the type of practice conducted and what are the characteristics of the locality in which it is conducted. If the practice having the benefit of the covenant is a general practice, a restraint wide enough in terms to prohibit the covenantor from establishing practice nearby as a neurosurgeon or as an anaesthetist may well be wider than is reasonably necessary because a specialist of that type does not see patients directly, as does a doctor, but only upon a referral from a general practitioner so that, in truth, there is no real likelihood of competition between the specialist and the general practitioner for the same patients: see e.g. Routh v Jones [1947] 1 All ER 758.
54 Again, a restraint protecting the goodwill of a general practice from competition within a radius of twenty kilometres of the surgery may be no greater than is necessary if the practice is the only practice in a small country town, so that established patients of a retiring partner may be quite willing to drive twenty kilometres to the nearest town if the retiring partner sets up practice there. However, such a covenant might well be completely unreasonable if the practice happens to be conducted in the demographic centre of Sydney.
55 In the present case, I have come to the conclusion that the restraints imposed in Clause 10.1(a) and (b) of the Sale of Practice Contract are greater than are reasonably necessary for the protection of the goodwill purchased by the Plaintiff, for the following reasons.
56 I give weight to the fact that the restraints were agreed to by the Defendant and that the Defendant was to be paid a substantial consideration in return. I do not accept the Defendant's submissions that she was in a position of commercial weakness in relation to the Plaintiff in the negotiation of the Contracts and that the Plaintiff has taken advantage of this inequality of bargaining position.
57 In my opinion, there is no evidence to support this submission. There is no evidence that the Defendant was suffering from Pethidine addiction at the time that she agreed to enter into the Contracts and she certainly did not inform the Plaintiff that she was in any difficulty in any respect at that time. There is no evidence that the Defendant was in any financial need or that she was subjected to any pressure by the Plaintiff. All that the evidence reveals is that, having considered the Plaintiff's offer for some time, the Defendant sought and obtained some variations to the terms and then decided to enter into the Contracts as a matter of her own free choice.
58 However, I take into account that there is no evidence that the Plaintiff and the Defendant actually negotiated the area and duration of the restraints. Dr Bateman's evidence is that the Sale of Practice Contract and the Practitioner Contract are examples of similar contracts that the Plaintiff has entered into with many doctors providing medical services at the Plaintiff's numerous medical centres. He says, however, that there is no standard contract and that each contract is drafted for each medical practitioner individually.
59 I do not think that the last statement is meant to be taken literally as the Contracts are obviously drawn by a lawyer and contain many clauses which would be described as "boiler plate". I take Dr Bateman to mean that terms such as the amount of consideration to be paid for the purchase of goodwill, the particular medical centre which is to be the site of the doctor's practice, holidays and the rate of remuneration for the Plaintiff's services would be negotiated with each doctor individually, but other clauses would be standard.
60 Elsewhere in his evidence describing the Plaintiff's operations generally, Dr Bateman says that the Plaintiff needs to be able to restrict doctors who cease practising from its medical centres within and area of eight kilometres. Since there is no evidence of negotiation with the Defendant of this particular term, I am prepared to infer that it was one of the standard terms in the Plaintiff's Sale of Practice Contract.
61 The evidence given by the Plaintiff in support of the reasonableness of a restraint extending for a radius of eight kilometres from the Leichhardt and Burwood Premises may be summarised thus.
62 First, Dr Bateman states that his involvement with the running and operation of the Plaintiff's medical centres for approximately twenty years shows that the majority of patients who attend the centres live within a radius of approximately ten kilometres.
63 I can give little weight to this evidence. It was not supported by any particulars or other detail which could make such a generalisation meaningful. The Plaintiff has fourteen medical centres in Sydney, some in densely populated areas such as George Street Sydney, Darlinghurst Road Darlinghurst, and Short Street Leichhardt, and others in much less densely populated areas as Ingleburn, Campbelltown, Mt Druitt and Castle Hill. The Plaintiff also has medical centres outside Sydney in Dubbo and Dapto. Is this evidence of Dr Bateman intended to reflect an averaging of patient domiciles within all the areas in which its medical centres are located? If so, that sort of averaging does not assist in determining what protection is necessary for the goodwill of the Plaintiff's Leichhardt Premises, which is the only subject of concern in the present case. What might be an entirely reasonable protection for the goodwill of a practice conducted at the Mt Druitt centre or the Dapto centre, having regard to their particular demographics, might be seen as completely unreasonable when the demographics relevant to the Leichhardt Premises are known.
64 Second, Dr Bateman states:
"The plaintiff needs to be able to restrict doctors who cease practicing from its medical centres within an area of 8 kilometres in order to protect its legitimate business interests and to ensure that it gets the benefit of the particular doctor's goodwill on the purchase of the doctor's practice."
