London Joint Stock Bank Ltd v MacMillan and Arthur: HL 21 Jun 1919

The duty which a customer owes to a bank is to draw cheques with reasonable care to prevent forgery, and if, owing to neglect of this duty, forgery takes place, the customer is liable for the loss. If a customer signs a cheque in blank and leaves it to an agent to fill up, he is bound by the instrument as filled up by the agent.
