36 The appellants contended that the decision in Gamser presented another reason why the appeal could not be re-opened. We agree with that contention. At 154, Aickin J stated:
The majority judgments in Bailey v. Marinoff appear to me to make it clear that there is no inherent power to set aside judgments by reason of changed circumstances on application made after the case has been finally disposed of. It is sufficient to quote what Menzies J. said (1971) 125 CLR, at pp 531-532:
This appeal is not concerned with the power of a court to
alter orders in pending litigation. It is concerned with the
power of a court to make an order in litigation which, without
any error or lack of jurisdiction, has been regularly concluded
and is no longer before the court. To recognize the problem is,
I think, to solve it. However wide the inherent jurisdiction of
a court may be to vary orders which have been made, it
cannot, in my opinion, extend (to) the making of orders in
litigation that has been brought regularly to an end.
37 In par [11] of the second amended notice of motion, which spelt out one of the grounds upon which the respondents relied in relation to Part A of the motion, it referred to the "conduct by the Appellants after the date of the judgment". Gamser makes it clear that there is no inherent power to set aside judgments by reason of changed circumstances on application made after the case has been finally disposed of.
38 Finally, in relation to proposed orders 4 and 5, we accept the appellant's submission that even if there was power to re-open, the Court would not permit such a course unless it was satisfied that the respondents would suffer "irremediable injustice" as identified in Codelfa Construction at 38. If there is merit in the respondents' claims regarding circumstances that arose after the Full Bench made the orders on 11 April 2007, we are unable to discern any bar to the respondents pursuing a remedy in the substantive proceedings.
Proposed orders 1, 2 and 3
39 We turn to proposed orders 1, 2 and 3. It will be recalled the appellants contended that there was no basis upon which the Court could make orders 1, 2 and 3 and the application to do so was, therefore, hopeless and should be dismissed. The respondents did not demur from the appellants' classification of the grounds supporting the proposed orders and it seems to us the classification was correct, namely, that the appellants' decision to withdraw Harmer's retainer was relevant to the question of costs and, secondly, that there had not been compliance with an undertaking or undertakings that had been given to the Court and that this was relevant to the question of costs of the appeal.
40 As it was submitted by the appellants, in relation to the first category the only thing the Court knows about the appellants' decision to withdraw Harmer's retainer is that the retainer was withdrawn with effect from 5 July 2007. That piece of information, of itself, says nothing about the appellants' conduct of the appeal such as might bear upon the question of costs and the respondents did not attempt to adduce any evidence that may have thrown more light on the matter. Importantly, however, the withdrawal of the retainer occurred after the appeal decision and orders were made. Consistent with the view taken by McDougall J in Leidreiter, we consider that subsequent events are incapable of establishing any "relevant delinquency" for the purpose of determining the basis upon which those costs should be paid. As we understood them, the respondents contended that it was possible that inferences might be drawn from the evidence in proceedings relating to their second amended motion that shows that circumstances relating to the change of solicitors was not altogether an event that occurred after the appeal decision was given. That is speculation on the respondents' part; there is nothing to indicate there was any "delinquency" on the part of the appellants, or for that matter, their solicitors during the appeal proceedings.
41 The same observations we have made in relation to the first category of grounds apply equally to the second category. Further, the remedy in relation to non-compliance with orders made by the Full Bench in the appeal relating to undertakings does not properly lie in orders 1, 2 and 3 but rather, as the appellants submitted, in proceedings to enforce the undertakings.
42 Between 24 April 2007 and 22 May 2007 the parties filed their submissions on costs as a result of the directions given by the Full Bench for the provision of written submissions on costs. By orders 2 and 3 the respondents now seek leave to admit in relation to the question of costs further evidence and leave to make further submissions as to costs. In circumstances where it would appear that the matters that have motivated the respondents to seek such orders relate to events that occurred after the appeal decision and orders were made, the respondents have not demonstrated any basis upon which we should countenance such orders.
43 We propose to dismiss the respondents' second amended notice of motion. That leaves the question of costs arising out of the appeal and the appellants' strike out motion.
Costs
44 The appellants contended that the respondents forthwith pay the appellants' costs of:
