By Roche J in Wisenthal v World Auxiliary Insurance Corp. Ltd. (1930) 38 Ll. Rep 54 that:
Fraud … was not mere lying. It was seeking to obtain an advantage, generally monetary, or to put some else at a disadvantage by lies and deceit. It would be sufficient to come within the definition of fraud if the jury thought that in the investigation [by the insurers] deceit had been used to secure payment or quicker payment of the money than would have been obtained if the truth had been told.
