Contract had, contract rights received.

Villareal sought to redeem five certificates of deposit purchased in the early 1980s. His primary legal theory, apparently selected to avoid problems with suing on the instruments themselves, was the quasi-contractual / restitution theory recognized in Texas law for “money had and received.” That theory ordinarily does not apply when an express contract (here, the CDs) addresses the subject. To escape that limitation, Villareal relied on Texas authority under which “an overpayment beyond what a contract provides may sometimes be recovered as unjust enrichment. If an overpayment qualifies as unjust enrichment, reasoned the district court, so should an underpayment.” (citation omitted, emphasis in original). The Fifth Circuit disagreed: “Overpayment typically falls outside a contract’s terms and, in that event, the contract would not ‘cover[] the subject matter of the parties’ dispute.’ By contrast, here the dispute involved the claimed non-payment of a debt evidenced by express contracts (the CDs). Unjust enrichment has no role to play.” (citation omitted, emphasis in original). Villareal v. Presidio Nat’l Bank (revised), No. 17-50765 (July 27, 2018, unpublished).
