(1) Such customer has authorized disclosure to such officer, employee or agent of such state or local agency or department thereof in accordance with Section 7473; or
(2) Such financial records are disclosed in response to an administrative subpoena or summons which meets the requirements of Section 7474; or
(3) Such financial records are disclosed in response to a search warrant which meets the requirements of Section 7475; or
(4) Such financial records are disclosed in response to a judicial subpoena or subpoena duces tecum which meets the requirements of Section 7476.
(b) Nothing in this section or in Sections 7473, 7474, 7475, and 7476 shall require a financial institution to inquire or determine that those seeking disclosure have duly complied with the requirements set forth therein, provided only that the customer authorization, administrative subpoena or summons, search warrant, or judicial subpoena or order served on or delivered to a financial institution pursuant to such sections shows compliance on its face.
(c) The financial institution shall maintain for a period of five years a record of all examinations or disclosures of the financial records of a customer pursuant to this chapter, including the identity of the person examining the financial records, the state or local agency or department thereof which he represents, and a copy of the customer authorization, subpoena, summons or search warrant providing for such examination or disclosure or a copy of the certification received pursuant to subdivision (b) of Section 7480. Any record maintained pursuant to this subdivision shall be available, within five days of request, during normal business hours for review by the customer at the office or branch where the customers account was located when examined or disclosed. A copy of such record shall be furnished to the customer upon request and payment of the reasonable cost thereof.
(d) Except as provided in Section 7480, this section is not intended to preclude a state or local law enforcement agency from initiating contact with a financial institution if there is reason to believe that the institution is a victim of a crime. After such contact by a law enforcement agency, if the financial institution believes it is a victim of a crime, it may, in its discretion, disclose relevant financial records pursuant to subdivision (c) of Section 7471.
