Banking in UK Law

The exception for fraud on the part of the beneficiary seeking to avail himself of the credit is a clear application of the maxim ex turpi causa non oritur actio or, if plain English is to be preferred, "fraud unravels all". The courts will not allow their process to be used by a dishonest person to carry out a fraud.

As to the effect of the ruling in the present case, in my judgment, it is clear that the Court of Justice concluded that the words "debt collection" in the carve out have a meaning capable of being applied to "transactions concerning payments" within the exemption in article 13B(d)(3) (judgment, paragraph 28, last sentence). It then has to be decided whether the actual transaction in question falls within the exemption or the carve out, and this will depend on its precise facts.

What facts ought to be known to the banker, i.e. what inquiries he should make, and what facts are sufficient to cause him reasonably to suspect that the customer la not the true owner, must depend upon current banking practice, and change as that practice changes.

In these circumstances, it is right that we should ask ourselves: why do we feel that it would be unjust to allow restitution in cases such as these? 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.
