His Lordship indicated that this analysis applied not only to unilateral contracts, but also to 'unilateral obligations' in agreements that also contain what he termed 'synallagmatic', or reciprocally binding, obligations. Similarly, it has been said that if a provision is expressed in terms of a condition precedent, this of itself gives it the character of essentiality: Perri v Coolangatta Investments Pty Ltd (1982) 149 CLR 537 at 554 per Mason J. Implicit in his Lordship's remarks is the proposition that a condition precedent is strictly construed. So where a provision lays down an act by one party as a condition precedent to the existence of an obligation on the part of the other party, the condition precedent will not be fulfilled until the former party does an act that strictly matches that described in the contract ." (emphasis added)
14 Mr Stoljar SC, who appears with Ms J Taylor of Counsel for the Plaintiffs, in a most able argument, has referred me to cases such as Neeta (Epping) Pty Ltd v Phillips (1974) 131 CLR 286, at 299, and Perri v Coolangatta Investments Pty Limited (1982) 149 CLR 537, as demonstrating that equity's flexibility as to time clauses extends with equal force to clauses which are properly classified as conditions precedent to the coming into operation of a contractual obligation.
15 I do not think that Neeta is authority for that proposition without qualification. Neeta was a paradigmatic vendor and purchaser suit. The purchaser, in breach of contract, failed to tender a Memorandum of Transfer on time. The vendor served a Notice to Complete but the vendor was herself in breach of the contract so that the Notice to Complete was invalid. It was not a case of non-fulfilment of a condition precedent but, rather, whether a breach by one party as to time for performance entitled the other party to make time of the essence.
16 On the other hand, Perri v Coolangatta is a case involving a condition precedent. The purchasers' obligation to complete the purchase of land was conditional upon the sale of their own home, but the purchasers did not promise to sell their home within any particular time. The High Court drew a distinction between a condition precedent fulfilment of which depended upon one contracting party performing a contractual promise by a certain time and a condition precedent fulfilment of which did not depend upon a party performing a contractual promise. In the first case, non-fulfilment of the promise is a breach of contract and the question is whether time for performance of the promise is, or can be made, of the essence, entitling the other party to terminate the contract. In the second case, there is no breach by one party so that the question of time for performance does not arise: if the condition is not fulfilled by the stipulated date the contract may be terminated without further ado: see per Gibbs CJ at 545-546; Brennan J at 566. Although Mason J was in dissent, his observation on general principle, which is referred to by Samuels JA in Tricontinental, is consistent with the law as stated by the other members of the High Court in Perri.
17 As I have said, in this case the Deed of Settlement does not provide for the Plaintiffs to incur an obligation, not previously existing, which is to be performed at a particular time in order to receive in exchange a particular benefit. It is a contract which provides only for one thing, that is, that an existing debt of the Plaintiffs to the Defendant - repayment of which has long been in default and enforcement long delayed - will be discharged in full if payment of a lesser amount is made by a certain time. Certainty of time for payment and the avoidance thereby of further delay and uncertainty as to enforcement of the Defendant's rights were the very essence of the benefit for which the Defendant was contracting, as appears from the face of the document and from the context of the transaction.
18 In my view, payment of $2M by 5pm on 12 June 2009 in accordance with clause 7(b) of the Deed of Settlement was of the essence of the contract and was the precondition for the operation of clause 9. That precondition not having been fulfilled in accordance with its terms, the Defendant has never become obliged to accept the accord and satisfaction provided in that clause. For these reasons, the Plaintiffs' Summons must be dismissed.
