United States Department of Natural Resources of the Commonwealth of Puerto Rico v. Ernst Jacob GmbH & Co. KG; Shipowners Insurance & Guaranty Company, Ltd.: United States Department of Natural Resources of the Commonwealth of Puerto Rico v. Ernst Jacob GmbH & Co. KG; Shipowners Insurance & Guaranty Company, Ltd.
The First Circuit held that it possesses appellate jurisdiction over an interlocutory appeal in an Oil Pollution Act case because the litigation includes third-party admiralty claims. On the merits, the court reversed the District Court's grant of summary judgment, ruling that liability for natural resource damages must be determined by a preponderance of the evidence rather than under the deferential arbitrary-and-capricious standard.
