140 In my view the circumstances of this case are peculiar. The Contract did not specify a fixed settlement date. Rather, it depended on certain events occurring. Those events were peculiarly under the control of, and within the knowledge of, the defendant. In those circumstances, I think the defendant bore some responsibility to advise the plaintiffs, clearly and unequivocally, that the events had occurred. On the defendant's case the event that triggered settlement was the lodging of the application for new titles. As I put it, somewhat euphemistically, to counsel for the defendant in closing, if the finger on the trigger is that of the vendor, I would have thought that there was an onus (using that word in a non-technical sense) on the defendant to advise the other party that the trigger had been pulled. This will not always be the case. However, in the circumstances that I have outlined and in the absence of advice from the defendant that there was a fixed and certain date for settlement under the terms of the Contract, it was not unreasonable for the plaintiffs to have proceeded on the (mistaken) impression that the time for settlement had not yet arrived.
