METROPOLITAN POLICE COMMISSIONER v CHARLES  AC 177 (HL)
Under the 'old' law of deception offences, a causal link between the deception and the obtaining could be implied where D wrote a guaranteed cheque, even where the victim had admitted that they had not considered whether the bank would honour the cheque. The 'new' ;aw of fraud does not require obtaining, so this principle is no longer necessary. However the case can still be used as authority for the implied representations which a person makes when using a cheque guarantee card.
