Chartis insured Lasalle Bank under certain surplus lines policies covering Lasalle’s business trusts. The insurance policies contained mandatory arbitration agreements. After a dispute arose between the parties, Chartis initiated a tripartite arbitration through the AAA as per the agreement. The arbitration entailed more than sixty (60) days of evidentiary hearings, which concluded on September 22, 2010. During the pendency of the arbitration, Chartis discovered that Charles Ennis, one of the three agreed-upon arbitrators, had concealed a past adversarial relationship with Chartis affiliates, and requested his removal through the AAA. After reviewing supplemental disclosures by Ennis, the AAA rejected Chartis’ request and the arbitration was concluded. The panel thereafter issued an award, and the parties and arbitrators entered into a Confidentiality Order. Chartis immediately filed an action in court to vacate the award, based in part on Ennis’ purported “evident partiality.” Chartis moved to seal the award pursuant to the Confidentiality Order, and also moved for permission to seek limited discovery on Ennis’ prior adversarial relationship with the Chartis affiliates. The court denied the motion to seal, but allowed Chartis the opportunity to redact specified portions of the award. The Court granted Chartis’ motion for discovery of Ennis’s past adversarial relationship to Chartis affiliates. Chartis Specialty Ins. Co. v. Lasalle Bank, N.A., C.A. No. 6103-VCN (Del. Ch. July 29, 2011).
