Can a drawer-depositor who entrusted his check books, credit cards, passbooks, bank statements and cancelled checks to his secretary and who had introduced the secretary to the bank for purposes of reconciliation of his accounts hold the drawee bank liable for the amounts withdrawn by the secretary by forging his signature on the checks?

No, he is precluded from setting up the forgery due to his own negligence in entrusting to his secretary his credit cards and check book including the verification of his statements of account. (Ilusorio v. CA, G.R. No. 139130, Nov. 27, 2002)
