12 As to the amount of the security to be ordered, it seems clear from the review of the cases by the Court of Appeal in Procon Ltd v Provincial Building Co Ltd [1984] 2 All ER 368, that there is no justification for an arbitrary[1] discount of one third of the genuinely estimated party and party costs of the applicant rather than ordering security on a full indemnity basis. That discount had been asserted as a conventional approach by the editors of the Supreme Court Practice. The court did however acknowledge that where the application is made at a very early stage in the proceedings, it may be appropriate to make an arbitrary[1] discount of the estimated probable future costs having regard to the possibilities of settlement. With respect, I would not have thought that this was a factor which could be taken into account only at a "very early stage" of the proceedings. Be that as it may, it seems to me that it could be unnecessarily oppressive to the plaintiff company to require it to give security now for costs which may not be incurred. The parties estimate that the case will last 50 days. It may however last only a small part of that time. I see no injustice in making an order securing the defendants' costs up to the end of the first 10 days of the trial to the amount of $72,000 and adjourning the further hearing of this application to the commencement of the trial so that the trial judge himself may determine what security, if any, should be given beyond that period of time. By that stage, and as the trial progresses, the court will be in a far better position than I to determine the likely length of the trial. Forewarned of the possibility of a renewed application by the defendants, the plaintiff company can in the meantime take steps to enable it to promptly reply with any further order made.
