The Washington Supreme Court recently held that an arbitration award does not transform an unliquidated claim into a fully liquidated sum entitling the prevailing party to prejudgment interest. The underlying dispute arose out of a building contract between the Department of Corrections and Fluor Daniels (“Fluor”). The parties agreed to resolve the dispute in binding arbitration. The dispute proceeded to arbitration and the arbitrator found in favor of Flour Daniels for $5,997,645. Three weeks later, Fluor reduced the award to judgment and sought prejudgment interest from the date of the arbitration until judgment.
The court held that an arbitration decision generally does not convert unliquidated damages into liquidated damages and does not entitle the winner to prejudgment interest between the date of the arbitration decision and entry of judgment. Rather, unliquidated damages accrue interest from the date of judgment, not the date of an arbitration award. State of Washington Department of Corrections v. Fluor Daniel and Fireman’s Fund Ins. Co., Case No. 78290-3 (Wash. July 6, 2007).
