Federal courts have admiralty jurisdiction to enforce the judgment of a foreign, non-admiralty court if the claim underlying the judgment is maritime under federal law, the U.S. Court of Appeals for the Second Circuit said Thursday.

Overturning a lower court, the Second Circuit found that admiralty jurisdiction exists under 28 U.S.C. §1333 and reinstated a case seeking to enforce a plaintiff’s judgment over a contract for future ocean freight rates imposed in England.
