Okla. Stat. tit. 12A, § 4-214
(b) A
collecting bank returns an item when it is sent or delivered to the bank's customer or transferor or pursuant to its instructions.
(c) A
depositary bank that is also the payor may charge back the amount of an item to its customer's account or obtain refund in accordance with the section governing return of an item received by a payor bank for credit on its books (Section 12A-4-301 of this title).
(d) The
right to charge back is not affected by:
(1) Previous use of a credit given for the
item; or
(2) Failure by any bank to exercise ordinary care with respect to the item, but a bank so failing remains liable.
(e) A failure to charge back or claim refund does not affect other
rights of the bank against the customer or any other party.
(f) If credit is given in dollars as the equivalent of the
value of an item payable in foreign money, the dollar amount of any charge-back or refund must be calculated on the basis of the bank-offered spot rate for the foreign money prevailing on the day when the person entitled to the charge-back or refund learns that it will not receive payment in ordinary course.
Oklahoma Code Comment
Under pre-revision subsection
4-212(6), Oklahoma had changed the uniform Act and provided that a charge-back should be measured by the rate in effect on the day credit was given. This rule had little to recommend it, either to the bank or the customer, and subsection (f) of this Section returns to the uniform rule of using a current date.
