SEATTLE - Because an insured failed to prove that its experts' methods for determining the cause of a collapse were based on a theory "generally accepted in the scientific community," a trial court did not err in granting the insurer's motion for summary judgment, the Division I Washington Court of Appeals said Aug. 19 (Lake Chelan Shores Homeowners Association v. St. Paul Fire & Marine Insurance Co., et al., No. 66636-3-I, Wash. App., Div. 1; 2013 Wash. App. LEXIS 1922).
