Banking and Finance in UK Law

The answer must be that, where an innocent defendant's position is so changed that he will suffer an injustice if called upon to repay or to repay in full, the injustice of requiring him so to repay outweighs the injustice of denying the plaintiff restitution.

The object of the direction, as the Treasury acknowledges, was to shut the Bank out of the UK financial sector, and that has been its effect. Before the direction, the Bank had a substantial international business, much of it international trade finance transacted through London.

I would not go so far as to say that the Schedule 7 direction in this case had no rational connection with the objective of frustrating as far as possible Iran's weapons programmes.

In my opinion, unless the Act expressly or impliedly excluded any relevant duty of consultation, it is obvious that fairness in this case required that Bank Mellat should have had an opportunity to make representations before the direction was made. In the first place, although in point of form directed to other financial institutions in the United Kingdom, this was in fact a targeted measure directed at two specific companies, Bank Mellat and IRISL.

That is to adopt too dogmatic an approach to what should in my opinion be a broad, merits-based judgment which takes account of the public and private interests involved and also takes account of all the facts of the case, focusing attention on the crucial question whether, in all the circumstances, a party is misusing or abusing the process of the court by seeking to raise before it the issue which could have been raised before.

This ingredient is also not in issue. The conduct of the named senior officials of the Banking Supervision Department of the Bank was in the exercise of public functions. Moreover, it is not disputed that the principles of vicarious liability apply as much to misfeasance in public office as to other torts involving malice, knowledge or intention: Racz v. Home Office [1994] 2 A.C. 45.

Their Lordships consider that this type of box-ticking approach does not do justice to the complexity of a decision as to whether or not to grant an interlocutory injunction.
