21 The short minutes of 26 March 2008, although made by consent, are not part of the contract, but part of the decree for specific performance to facilitate performance of the pre-existing contract. In those circumstances, it is far from clear that time for compliance with an order that does not specify a time for compliance can be fixed by a unilateral notice from a party: the rules provide a method for fixing a time for compliance with an order of the Court where one is not specified in the order, by application under Uniform Civil Procedure Rules r 36.5(2)(b) for the Court to fix a time for compliance. That is not to say that a notice might not have some evidentiary value in establishing unreasonable delay for evidentiary or discretionary purposes.
22 But even if a notice could effectively make time for compliance with order 4 essential, this notice was not effective for that purpose, for two reasons. First, the time allowed was some five weeks. It is not always necessary that a notice to perform allow enough time for all the remaining steps to be taken, but a notice must be reasonable in all the circumstances. Those circumstances can and often do include prior delay by the recipient - and such prior delay is not to be permitted to enlarge the period of notice that would otherwise be required [Michael Realty Pty Limited v Carr [1977] 1 NSWLR 553]. But "all the circumstances" must involve, amongst other matters, the expedition with which the contract has proceeded to that stage, and the approach of each of the parties to performance of their obligations under it. In this respect it is relevant to have regard to the Mordues' prompt payment of the costs of the application for subdivision in June 2008, having been requested in late May. Taking all the circumstances together, a period of five weeks in August - when some time longer than that, probably about two months, was reasonably required to complete all the works - was not reasonable.
23 More significantly, perhaps, assuming that a notice to perform could have been given, this was not an effective notice to perform. While it is not essential to the validation of a Notice to Complete that it expressly makes time of the essence, if by appropriate words it conveys a threat to terminate in the event of non-compliance [Abraham v Mallon (1975) 1 BPR 9157], a notice to perform must at least call on the recipient to perform the outstanding obligation. In this case, the outstanding obligation was that imposed by clause 4 of the short minutes, namely "To do all things and sign all the documents necessary to satisfy each and every condition of the approval ...". The letter of 21 August did not do that, but simply advised "Unless the plan of subdivision is registered in accordance with clause A 6.2 within six months of further order, by 26 September 2008 our client will instruct us to approach the Court to obtain leave to exercise her rights to rescind the contract pursuant to the terms of the contract."
