Certain Underwriters at Lloyd's, London v. Southern Natural Gas Company

Southern Natural Gas Company (Sonat) sued Certain Underwriters at Lloyd's London and Certain London Marketing Insurance Companies (Phase III), alleging breach of numerous umbrella and excess liability policies. Sonat contended the insurance companies failed to pay certain environmental-remediation costs. The trial court granted summary judgment in favor of the insurers based on prior trials in Phases I and II of the case; Sonat appealed, and the insurers cross-appealed Phase III's outcome. Finding no abuse of the trial court's discretion, the Supreme Court affirmed.
