“[A]n applicant for fortification must satisfy three requirements. First, that the court can make an intelligent estimate which is informed and realistic, although not necessarily entirely scientific, of the likely amount of any loss which might be suffered by the applicant by reason of making the freezing order. Secondly, that the applicant has shown a sufficient level of risk of loss to require fortification, that it has shown a good arguable case to that effect. Thirdly, that the making of the interim order is or was a cause without which the relevant loss would not be, or would not have been, suffered. In relation to that third requirement, whilst it is open to the respondent to the application to demonstrate that there is no causal link between the granting of the injunction and the loss in question, if disproving that asserted causal link, as to which a good arguable case is shown, requires the deployment of extensive contentious evidence and argument, then that is not an exercise to be attempted at the interlocutory stage.”
“24 … In many cases the fact that there is a risk of loss will be obvious merely from the general situation, and while it may not be possible to put anything like a precise figure on the loss, the court will, if necessary, do what it can on the evidence before it to reach an appropriate figure. The courts are well accustomed to assessing the appropriate value to be given to things whose valuation is difficult. In some cases it will be possible to make a more precise or confident assessment than in others. The mere absence of particularised evidence does not mean that there is no evidence of a risk of loss…”
“However, it is accepted that this court does not have the material before it to conclude that there would be no possibility of practical difficulties, notwithstanding the willingness by SHNT, CMT and HIT to submit to the jurisdiction to make good the undertaking.”
