Prospects of success
47The respondent submitted that the grounds of appeal have poor prospects of success and noted that they were not supported by written submissions. However, the respondent did not go so far as to suggest that the appeal was not bona fide.
48There was some debate between the parties as to whether the order of Windeyer AJ was properly described as a mandatory order rather than an order for specific performance. Strictly, orders in the nature of specific performance are described as mandatory orders where the contract is executed on one side and the plaintiff simply requires enforcement of a legal right. This is often referred to a "quasi-specific performance" or relief "in the nature of specific performance" or relief "approximate to specific performance": see Young, Croft, Smith, On Equity Lawbook Co 2009 at [16.870] and the authorities there cited.
49In this case, the relevant agreement appears to have been executed on one side, at least in terms of the appellant having transferred his interest in Teffcog to the respondent. Thus, the language of Windeyer AJ referring to the order as a mandatory order was appropriate. Ultimately, however, nothing turns on this issue for present purposes.
50The grounds of appeal raise issues concerning the proper construction of the agreement between the parties.
51The appellant's essential complaint is that the respondent could not satisfy his obligation under cl 5.9 of the agreement by causing companies which he controlled to make payments to the ATO of his half-share of the tax liability. Rather the respondent was required to make that payment personally and this had not been established on the evidence before Windeyer AJ. It followed on the appellant's argument, that the respondent should have been denied equitable relief because he was unable to and had not performed his mutual promise under cl 5.9 of the agreement.
52In my view, the appellant's argument on the proper construction of the agreement is weak. The argument fails to distinguish between the existence of a liability and the means of discharge of a liability. Nothing in the language of cl 5.9 of the agreement suggests that either party could not discharge their respective obligations to pay one half of the tax debts of any of the relevant entities (including Teffcog) to the ATO, by utilising whatever moneys were available to them, either personally or through entities over which they exercised control. My view is obviously provisional and without the benefit of argument. As there is no suggestion that the appeal is not bona fide, I must assume that the alternative construction which the appellant seeks to advance is at least arguable.
53Neither party made any submissions concerning the "offset" argument which the appellant's solicitor foreshadowed in his affidavit opposing the application for security for costs. Two observations are however appropriate. First, the argument would appear to rely upon evidence of matters occurring post-judgment.
54Secondly, the appellant's description of the payment received by Teffcog from a third party as giving rise to an "offset" against the judgment below is somewhat inapt. Rather, the appellant's contention seems to be that the effect of the payment received by Teffcog under the compromise with its accountants was to partly reduce or extinguish the appellant's liability (for the benefit of Teffcog) under cl 5.9 of the agreement. The legal basis on which this result might occur was left unexplained by the appellant.
55It is not appropriate to embark on any consideration of the likely strength of this foreshadowed ground of appeal. It is sufficient to observe that it was not suggested by the respondent that the contention is manifestly hopeless.
56Overall, I proceed on the basis that the appeal is bona fide and at least arguable.
