Arbitration is the proper forum for adjudicating a labor dispute between a Long Island shipping company and a union that boils down to when their collective bargaining agreement expired, a federal appeals court ruled. A three-judge panel of the U.S. Circuit Court of Appeals for the D.C. Circuit rejected Liberty Maritime Corp’s argument that the lower court lacked jurisdiction to consider a lawsuit to compel arbitration filed by Maritime Engineers’ Beneficial Association (MEBA). The union represented supervisory personnel on Liberty’s bulk-carrier ships.
