“What is required in each case is to examine what on the particular facts of the case the consequences of granting or withholding of the injunction is [sic] likely to be. If it appears that the injunction is likely to cause irremediable prejudice to the defendant, a court may be reluctant to grant it unless satisfied that the chances that it will turn out to have been wrongly granted are low; that is to say, that the court will feel, as Megarry J said in Shepherd Homes Ltd v Sandham[1971] Ch 340 , 351, ‘a high degree of assurance that at the trial it will appear that the injunction was rightly granted’.”
“In my judgment, having read the learned judge’s judgment more than once, it seems to me that he took the view that not only did the respondents have an arguable case, but that it was a strong arguable case, and the defences raised against it were not in themselves very strong, although there was one point of law which was not decided. Having concluded that there was an arguable case on the respondents’ side, he then of course turned to the question of the balance of convenience.”
“I fully appreciate that if one simply does the damages exercise, to which reference is so often made when American Cyanamid is quoted, the result might seem to be that no interlocutory injunction should go in the circumstances of the instant case. On the other hand, when one bears in mind that that is only part of the balance of the risk of doing an injustice and looks at all the other considerations – to which I have referred and which are also in my mind but which I have not gone into in detail which are clear on the papers – I think that the balance in the circumstances of the instant case does require the grant of an interlocutory injunction against the appellants.”
