“The taking of an overdraft from a bank, even in breach of instructions, is no more than accepting a loan: it cannot be stealing- R. v. Prince 11 Cox C.C. 193. And in Cuthbert v. Robarts, Lubbock & Co. [1909] 2 Ch.D. 226 it was held that when a client paid a cheque to his banker and drew another for payment before the effects of the one he paid was cleared, he was only asking the bank for a loan.”
