Background

  • Viper Tradeshow Transportation contracted with AVMA on March 14, 2016 to provide exposition and convention services for AVMA’s 2018–2020 conventions, with specified duties, fee structure, and an integration clause.
  • The contract contained a termination clause allowing AVMA, in its sole discretion, to terminate “without further liability” with at least six months’ written notice; AVMA also could retain Viper’s data and materials.
  • After Viper performed 2018 work, AVMA terminated the contract as to 2019–2020 on December 10, 2018, citing unsatisfactory performance and requesting return of materials; the six‑month notice requirement was met.
  • Viper claimed AVMA then used Viper’s plans/graphics and refused to pay invoices Viper issued for work already done or for discretionary discounts, and sued for breach, quantum meruit, and unjust enrichment (seeking approx. $168,625.80).
  • The circuit court dismissed all counts with prejudice under section 2‑615. Viper did not contest the breach count on appeal and challenged only the dismissals of quantum meruit and unjust enrichment; the appellate court affirmed.

Issues

Issue Plaintiff's Argument Defendant's Argument Held
Whether quantum meruit recovery is available despite an express written contract and AVMA’s discretionary termination Viper: termination ended the contract as to 2019, so quasi‑contract recovery for services/materials is available AVMA: an express contract governed the parties’ relationship and expressly allowed termination; quantum meruit is barred when an express contract covers the subject matter Court: Dismissed quantum meruit; express contract controls and precludes quantum meruit for the same subject matter
Whether unjust enrichment claim survives where an express written contract governs Viper: AVMA unjustly retained benefit of Viper’s work and materials after termination AVMA: unjust enrichment inapplicable because an express contract governs and provides the parties’ agreed remedies/risks Court: Dismissed unjust enrichment; remedy unavailable where an express contract covers the dispute
