In a watershed decision concerning the scope of maritime liens under the U.S. Commercial Instruments and Maritime Lien Act (“CIMLA”), the District Court for the Southern District of New York recently held that OW Bunker entities did not have valid maritime liens for the supply of bunkers to vessels. In the first decision by a U.S. court to hold that the OW Bunker entities do not have maritime liens under U.S. law, the Court underscored that maritime liens are an extraordinary remedy for suppliers of necessaries to vessels and cannot be assumed to apply in all circumstances. This ruling, together with previous rulings by other courts holding physical suppliers did not have valid maritime liens, may leave no party with a valid maritime lien arising from the OW Bunker collapse and bankruptcies. Without a maritime lien, suppliers of necessaries to vessels do not have a right to arrest. See the full client alert here.
