Mutual Finance Ltd v John Wetton and Sons Ltd: 1937

A relative of a forger gave a guarantee in circumstances where the forger had been threatened with prosecution. He now pleaded economic duress.
Held: The guarantee should be set aside. The court considered the distinction between dures and undue influence. Porter J said: ‘Not only is no direct threat necessary, but no promise need be given to abstain from a prosecution. It is enough if the undertaking was given owing to a desire to prevent prosecution and that desire were known to those to whom the undertaking was given. In such a case one may imply (as I do here) a term in the contract that no prosecution should take place . . A threat made by a party to a contract may be illegitimate when coupled with a demand for payment even where the threat is one an action which would otherwise be lawful.’
The line between permissible forms of persuasion and undue influence is ultimately regulated by considerations of public policy.
