Union Electric Company v. AEGIS Energy Syndicate 1225
713 F.3d 366
8th Cir.
2013

Background

  • UEC sued AEGIS for coverage under an excess insurance policy after a Taum Sauk hydroelectric plant accident in Missouri.
  • Policy provides a three-step dispute process: negotiation, mediation, then binding arbitration under Condition M.
  • Endorsement states Missouri law governs and that each party submits to Missouri courts' jurisdiction for any dispute relating to the insurance or a claim.
  • Court applies Missouri contract law and reads the policy as a whole, giving language its plain meaning; endorsements supplant conflicting general provisions.
  • AEGIS argues endorsement does not replace the arbitration clause; UEC argues the endorsement replaces arbitration by granting MO jurisdiction for all disputes.
  • District court held that the endorsement supplants the arbitration provision; the panel affirms.
