What his Honour there said, of course, took account and must be read against the background of the decision of the High Court of Australia in Beecham Group Ltd v Bristol Laboratories Pty Ltd (1968) 118 CLR 618 at 622 by the Full Court of the High Court, particularly what was said there as to the criterion of the fairly arguable case and the relevance of the relevant strength of the parties' cases. Whilst the formulation in American Cyanamid Co v Ethicon Ltd [1975] AC 396 is now to be preferred to that in the Beecham Group case (see The Australian Coarse Grain Pool Pty Ltd v The Barley Marketing Board of Queensland (1982) 57 ALJR 425; Tableland Peanuts Pty Ltd v The Peanut Marketing Board (1984) 58 ALJR 283; and A v Hayden (No 1) (1984) 59 ALJR 1), the strength or weakness of the plaintiff's case may still be a factor in the assessment of the balance of convenience: see Castlemaine Tooheys Ltd v The State of South Australia (1986) 161 CLR 148 at 153 - 5 per Mason ACJ.
11 In Martin Engineering Company v Trison Holdings Pty Ltd (1988) AIPC 90-511, Gummow J, then a Judge of the Federal Court, discussed the application of the principles relating to interlocutory injunctions in patent cases, and drew attention to the consideration applicable in many such cases that a defendant who sets out to act in the face of a claimed patent does so with eyes open to the possibility that the patent will be found valid and enforced. That principle was applied also by Burchett J in the Federal Court in Tidy Tea Ltd v Unilever Australia Ltd (1995) 32 IPR 405. Whilst that proposition was enunciated in patent cases, it seems to me that it is not limited to cases that are strictly or technically patent cases, but has, in appropriate circumstances, wider application. In cases where it is known that there is a claim that the defendant's actions are in breach of a duty of confidentiality, or even in the face of a known claim that there is a restraint by contract of its activity, unless the claim is manifestly bad, the situation that the defendant faces is that it has chosen, for its own commercial reasons, to embark on its course of action, knowing that the claim has been made and may ultimately be enforced by the courts. A useful discussion of a number of the considerations in cases such as the present is contained in the judgment of Malcolm CJ in the decision of the Supreme Court of Western Australia in Taylor v Delcove Pty Ltd 9 December 1996 SCWA unreported, on an appeal from the Chief Judge of the District Court of that State, as follows:
"In the context of a covenant in restraint of trade, it is apparent that for a restraint of trade to be reasonable in the interests of the parties, it must afford no more than adequate protection to the party in whose favour it is imposed and it is in this case the duty or burden upon the person who seeks to rely upon the restraint, namely, the respondent, to establish that it is reasonable in all the circumstances. In this context the learned Chief Judge came to the conclusion that this was truly 'a trade agreement between traders' as in Esso Petroleum Co Ltd v Harpers Garage (Stourport) Ltd [1968] AC 269. In that case at 327, Lord Pearce stated the test as being whether it was in the interests of the community that the restraint should as between the parties be held reasonable and enforceable. The relevant authorities in this area were recently collected in my judgment in Britten v Bishop , unreported; FCt SCt of WA; Library No 960560; 25 September 1996 at 3-5.
On the application of the principles there stated at an interlocutory stage, I am of the opinion that there is a serious question to be tried in this case in relation to the reasonableness of the restraint.
So far as the balance of convenience is concerned, a number of factors have been adverted to. The first is that related to the adequacy or otherwise of damages at common law. It was argued below that there had already been two businesses opened in contravention of the contract, giving rise to questions of delay and estoppel or acquiescence in relation to the application for an injunction.
So far as the question whether damages would be an adequate remedy is concerned, the learned Chief Judge concluded that this was an instance where the injunction ought to be granted 'because of the manner in which this situation is developing' His Honour came to the conclusion that damages may not be an adequate remedy if the appellants continued to open businesses in the restrained area. While the claim which the respondents make is a claim for damages for loss of the goodwill of the business which they acquired and sounds in damages, that, of course, is not their only claim. They claim they have lost that amount as of the date of the issue of the writ. They also claim what is in effect a permanent injunction in the sense that it is an injunction to last for the balance of the 5-year period in relation to the benefit of the covenant. In the circumstances as they now stand, damages will not themselves necessarily be an adequate remedy. As has been held previously, damages are regarded as rarely constituting an adequate remedy for the invasion of proprietary or possessory rights: Beswicke v Alner [1926] VLR 72 at 77.
In such a case as this, the purpose of the interlocutory injunction is to restrain the appellants from activity which could cause further damage to the respondent and inhibit the respondent's ability to sell the business if it were minded to do so or otherwise protect the goodwill which was sought to be protected by the relevant clause. On the other hand, there is no reason why the appellants would not be adequately protected by the undertaking which they have obtained from the respondent to compensate them if it turns out that the interlocutory injunction should not have been granted.
In my opinion, the ground that the learned Judge was in error in holding that the respondent would not have an adequate remedy in damages as an alternative to the grant of injunction has not been made out."
12 Bearing those matters in mind, I turn to the contentions in this application. It was contended by Mr Douglas, of Queen's Counsel for the plaintiff, that it had shown that it had a fairly arguable case that it had a proprietary right because, at the time of the agreement, it had a monopoly by the patent; or that it had imparted confidential information to the first defendant (and through it to the second defendant); and/or that there was a fiduciary relationship between the plaintiff and the defendants. Even if none of the above alone sufficed, in conjunction with such rights it had contractual rights arising from the 1984 contract, and in particular from the provisions of clause 15 thereof. He said further that, even if none of the other bases was made out, it undoubtedly had a claim arising from the contract itself. This alone provided it with a fairly arguable claim for relief. Damages, he said, were not an adequate remedy because the plaintiff's proprietary interest, in the sense set out earlier, would be infringed, or, even if there were no proprietary interest, the plaintiff clearly had a substantial share in the market for mining supports at the time that contention between the parties broke out in 1999, and had the goodwill arising from that market share, which would be destroyed or eroded by the defendants being allowed to manufacture and supply direct while the matter came to court for final decision of the rights and wrongs. He said that damages are inadequate, because it is always difficult to assess damages in relation to the erosion of goodwill, and particularly would it be so in this case. Here, if the plaintiff claimed subsequently that it had lost customers or market share by reason of the defendants' actions, the defendants would answer that it could not be demonstrated whether the market share was lost by reason of their actions, or simply by reason of the increasing competitiveness of the market, ie, even if the defendants gained customers, the customers would have been lost by the plaintiff in any event to other competitors, were the defendants kept out of the market in the meantime. These questions would obviously be difficult to determine.
13 Mr Grieve made bold assertions in answer to the plaintiff's claim for the greater interlocutory relief it sought. He said that, insofar as the plaintiff's claim depended on breach of contract, damages would be sufficient, and, in any event, if the defendants were wrongly kept out of the market, they would have to depend on the plaintiff's undertaking as to damages, and they would face the same difficulty with assessment under the undertaking as the plaintiff would face if thrown back solely upon its remedy in damages. He drew attention to the onesidedness of the 1984 contract as written, and characterised as important the public interest in competitiveness in this market, particularly in the context of the importance given to competition in the markets of the world in the 1990s. So far as the contract claim is concerned, he boldly said that I should find that the plaintiff had no arguable case, because the restraints imposed by clause 15 were palpably bad, or there was little chance of their being upheld. In this regard he pointed to the vagueness of the promise by reason of the presence of the words "similar to", to the lack of geographical definition of the restraint, and to the length of the five year restraint after termination of the contract. He said that the Tidy Tea doctrine can have no application if any lawyer worth his (or her) salt who looked at a restraint would say that this restraint "hasn't got a snowball's chance" of being upheld. And that was the situation in relation to this restraint.
14 What I have set out above does not do full justice to the detailed arguments of law and of fact put to me by Mr Douglas and by Mr Grieve in their vigorous debate upon this application. However, it does draw attention to some of the major factors which I have taken into account in determining the application.
15 The first thing I should say is that I do not accede to Mr Grieve's submissions in so far as they suggest either that the plaintiff has not made out a reasonably arguable case, or that that case is very weak. In my view reasonable arguments have been put forward in support of the plaintiff's case, especially upon the contract, and bearing in mind that the restraint as sought is wholly within the period of the continuing existence of the contract. In saying this I am not unmindful that it is possible for a restraint, even within the contract period, to be struck down as unreasonable: A Schroeder Music Publishing Co Ltd v Macaulay (formerly Instone) [1974] 1 WLR 1308; Buckenara v Hawthorn Football Club Ltd [1988] VR 39; Watson v Prager [1991] 1 WLR 726. However, it is true on the other hand that a reasonably arguable case has been put forward for the defendants that the contractual restraint may be struck down, and that the plaintiff may not succeed upon any of the other bases it contends for. This brings me back to the exercise as outlined by McLelland J, subject to the additional argument put by Mr Grieve that this was a case within the class referred to by McLelland J, where closer examination has to be made of the strength of the respective cases, because the decision of the interlocutory application in practical terms decides the issue between the parties. That submission, however, I do not accept. Whilst what occurs in the next two to four months may have some effect in this market, I do not think that that will foreclose the situation as between the parties. The questions of whether, and the degree to which, the contractual restraint will be upheld will have effect on the parties in the market far beyond that period.
16 Putting that contention aside, in deciding what is the just and convenient result, I have taken the whole of the evidence and all the contentions before me into account, including the contentions that I have outlined above. It does seem to me that this is a case in which the Tidy Tea doctrine does have application. I do not accept Mr Grieve's "snowball's chance" argument. Therefore, one factor to be taken into account is the fact that the defendants, knowing the existence of the contractual restraint, have chosen to enter on the course of action that they have entered on. Whilst they may suffer disadvantage in being restrained from open competition in the market during the short period about which we are speaking, what will be denied to them is the possibility or opportunity of taking further market share, which they do not now have. On the other hand, what will be eroded on the plaintiff's side, to the extent that erosion occurs, is an already existing market share. The defendants entered on their present course of action bearing in mind the risk that emanated from the restraint clause. It is important to remember the possibility that if the restraint as it stands is invalid it may be saved in part through the mechanism of the Restraint of Trade Act 1976, which the plaintiff has indicated its intention to rely on: see Kone Elevators Pty Ltd v McNay (1997) ATPR 41-564.
17 In all the circumstances, I have come to the conclusion that I ought to grant the continuing relief as sought by the plaintiff and ought not accede to the defendants' arguments that the restraint when granted should include the proposed clause (ab) and the increase of the figure of $100,000 to $250,000. The relief, even without these exceptions, substantially ameliorates the defendants' position by enabling it to use part of its manufacturing capacity to manufacture split sets to be sold direct. The plaintiff will during the restraint continue to source split sets from the defendants. In light of this, on the somewhat vague evidence given, I do not accept that the defendants' factories will need to be closed down or their staff put off in the comparatively short term during which relief is granted. Even without the limitations contended for by the defendants, the regime gives the defendants opportunity for further market penetration in respect of new customers and, in my view, the plaintiff's complaint is just that the further exceptions sought to the operation of the restraint even in the short term, would go too far and give it no effective or sufficient protection of its position.
18 Because of the urgency of the situation as it appears from the debate before me, it seems to me that every week will count. I do not intend simply to stand the matter over to Bergin J's expedition list on today week. I intend to give any direction that may be appropriate in the short term for the further advancement of the matter. In particular, I repeat the view which I expressed during argument that, whatever occurred on this application, the plaintiff should prepare the statement of claim, which is obviously necessary for the orderly conduct of the matter, by today week, and have that available before Bergin J when the matter goes before her Honour. I shall consider the necessity or appropriateness of any other directions that the parties come forward with when they bring in short minutes to give effect to the decision I have just announced. Upon the plaintiff by its counsel giving to the Court the usual undertaking as to damages, the existing restraints are continued up to and including Monday, 14 February 2000. The proceedings are stood over before me until noon on that day to bring in short minutes and for further consideration as to the question of costs.
