61 It may be that the apparent tension between the approach taken by Owen and Windeyer JJ and that of Barwick CJ in Morgan is more illusory than real. This is because the approach of Barwick CJ appears to canvass the intermediate steps by which a court will determine whether an order is ambiguous. As I understand the approach of Barwick CJ it is that there may be more than one possible meaning of an order but if on a process of construction a court is able to determine what is the real meaning of the order without resulting in any determination of ambiguity, this will be the meaning for the purpose of enforcement of the order.
62 The judgment of Lindgren J in Microsoft v Marks previously referred to contains a passage which is illustrative of this point. His Honour said:
The proposition that a contempt will not be found where the terms of an order or undertaking are unclear, ambiguous or apt to mislead (except, perhaps, if the prosecutor proved that the contemnor understood them in accordance with what the court holds to be their true meaning) must be distinguished from certain other propositions. It does not signify that there is no breach wherever there is difficulty in the construction of the terms of an order or injunction which it falls to a court to resolve. Nor does it signify that contempt will not be found wherever an alleged contemnor did not understand the terms of an order or injunction according to their true meaning, much less wherever an alleged contemnor was unaware that his or her conduct constituted a breach of the order or undertaking (cf Watkins v AJ Wright (Electrical Ltd) [1996] 3 All ER 31). (at 121).
63 Having regard to the above authorities I now turn to consider the provisions of par 1 of the dispute orders issued by Sams DP. As I read these provisions they appear to me to require that the respondent through its officers, employees and members cease from imposing a ban, limitation or restriction on work associated with ELLA on 29 February 2000 and, also direct the respondent etc. to refrain from imposing a ban, limitation or restriction on such work. Presumably the work as described refers to the administration of the test on 29 February 2000. I take the view that the meaning of par 1 is clear in one respect namely that the respondent is to desist from imposing a ban, limitation or restriction on work associated with ELLA on 29 February 2000 at any school conducted by the applicant, and that it must cease any such existing ban.
64 Whilst there may be a theoretical difficulty in the construction of the provisions of par 1 it is not such, in my view, that breach would not found entitlement at the suit of the applicant to an order under s139(3)(e) of the Act. There is no suggestion that the respondent did not understand the terms of par 1. In fact, it is clear from the evidence to which I referred that the respondent at all times was aware that the orders of Sams DP required it to lift the ban which had been imposed by it on ELLA and it refused to do so.
65 The next area of ambiguity relied upon by Mr Crawshaw arose out of the provisions of par 3 of the orders. It will be observed that s138(2)(b) requires a dispute order to "state a time within which the order is to be complied with or state a period during which it remains in force." Mr Crawshaw submitted that it was permissible to state either the time or the period but not both and secondly, par 3 having stated both created ambiguity as to the manner in which compliance was required. If, arguably, the provisions of par 1 applied only to work to be carried out which was associated with ELLA on 29 February 2000 then there would be no necessity for the order to remain in force for a period of seven days. In any event the fact that the order is to remain in force for this period was inconsistent with compliance by the time stipulated namely 6pm on 28 February.
66 In my opinion the resolution of this issue can be determined by reading the provisions of par 3 together with the provisions of par 1 which is the substantive dispute order issued by Sams DP. As I have earlier observed par 1 requires the cessation of the existing ban. In this context par 3 requires that the ban cease by 6pm on 28 February 2000 and requires that to the extent that the respondent must refrain from imposing any new ban, such restraint operates from the making of the orders and remains in force for a period of seven days.
67 Arguably, to the extent that the respondent was restrained from imposing any ban on and after the making of the orders for such period of seven days as exceeded the cessation of work on 29 February 2000, the order was superfluous. Such a situation might give rise to ambiguity in relevant circumstances. However in the circumstances where the application now being considered is confined to a breach of par 1 namely directed to work to be performed on 29 February 2000, no relevant ambiguity arises.
68 Accordingly, on this basis, the provisions of par 3 as framed read in conjunction with the provisions of par 1 create no ambiguity such as to preclude the making of an order under s139(3)(e) of the Act based on a breach of par 1.
69 I should add that Mr Menzies submitted that par 1 should be construed as applying not only to work associated with the administration of the test on 29 February 2000 but that those words also describe the type of test generally and therefore had the effect of applying to the administration of the ELLA test in days subsequent to 29 February 2000.
70 If Mr Menzies were correct in this assertion, par 1 would in my view give rise to ambiguity. Mr Menzies having submitted that this construction of the provisions of par 1 should be considered as an alternative thereby conceded, in my view, that there was ambiguity in the manner in which the provisions of par 1 were framed. If Mr Menzies were correct in this submission, it would have had the effect of enabling the respondent to succeed in these proceedings. However, I reject this alternative approach to construction as being open on the language used in par 1. It is clearly limited in my opinion to work associated with ELLA on 29 February 2000, that is to the work associated with the administration of that test on that day only.
71 For these reasons I reject the submission of the respondent I this regard.
