Okla. Stat. tit. 12A, § 3-418
Oklahoma Code Comment
1. This Section provides a finality of payment rule for Article 3 and 4 transactions, barring rescission of any payment made to (or accepted by) a party protected under sub section 3-418(c) . However, Sections 3-417 , 4-207 and 4-407 remain applicable. Sub sections 3-418(a) and (b) qualify the final payment rule, including the rule for banking institutions in Section 4-215 , by allowing a payor to rescind payment made under the circumstances set out in (a) or pursuant to the law of mistake and restitution.
2. Sub section 3-418(a) allows revocation of payment where the only mistake was a belief either that the drawer had not stopped payment or the drawer's signature was authorized. This qualifies the rule of Price v. Neal (see UCC § 3-417, Oklahoma and Official Comments), to the extent applicable. However, under sub section 3-418(c), this cannot be exercised against a person who took the instrument in good faith and for value, or who in good faith changed position in reliance on the payment (or acceptance). Sub section 3-418(b) allows revocation of payment based on any mistake that would provide a basis for restitution under the common law, again subject to sub section 3-418(c) .
3. Subject to the protection of sub section 3-418(c), these provisions allow a payor bank to rescind final payment in circumstances where there is no breach of presentment warranty under Section 3-417 , potentially altering the result in cases like Kirby v. First & Merchants Nat'l Bank, 210 Va. 88, 168 S.E.2d 273 (1969). See UCC § 4 - 301, Official Comment 7; F. MILLER & A. HARRELL, THE LAW OF MODERN PAYMENT SYSTEMS AND NOTES 18.02[4| (2d ed. 1992). Section 3-418 also rejects the pre-Code rule of 48 O.S. § 143 (repealed), which precluded recovery by the payor when a draft was paid on a forged drawer's signature.
4. This Section has a counterpart, of sorts, at sub section 4-302(b) , which allows a payor bank to defend on certain restitutionary grounds against liability for missing its midnight deadline, even in the absence of a breach of warranty. See UCC § 4-302, Official Comment 3.
