NATIONAL UNION FIRE INSURANCE COMPANY OF PITTSBURGH, PA. v. WESTLAKE CHEMICAL CORPORATION (Signed Opinion)
Annotate this CaseThe case in question arose from a multi-million-dollar loss suffered by Westlake Chemical Corporation and Axiall Corporation (the respondents) at their chlorine manufacturing plant in Natrium, West Virginia. The loss occurred when 90 tons of liquid chlorine leaked from a rupture in a railroad tanker car that had been recently repaired by third-party contractors. The liquid chlorine vaporized into a cloud or plume that caused corrosion damage to the equipment at the plant. The respondents claimed the damage costs from their insurance companies (the petitioners). However, the insurance companies denied coverage based on three exclusions in the insurance policies relating to corrosion, faulty workmanship, and contamination. The case reached the Supreme Court of Appeals of West Virginia, which was asked to review three orders of the Circuit Court of Marshall County, West Virginia, Business Court Division. The lower court had granted partial summary judgment to the respondents, finding that none of the three exclusions barred the respondents’ coverage claims. The Supreme Court of Appeals of West Virginia concluded that the lower court's orders were not final orders subject to appeal at this stage of the proceedings. This was due to unresolved issues of causation and damages, and because the orders did not conclusively determine the disputed controversy, resolve an important issue completely separate from the merits of the action, or were effectively unreviewable on appeal from a final judgment. Therefore, the court dismissed the appeal, without prejudice.
