Brussels, 20/03/2002 (Agence Europe) - On Wednesday, the European Commission decided to take the matter of its dispute with Greece before the Court of Justice. The dispute concerns the way in which the regulation on maritime cabotage is interpreted. The rules applying to ships' crews come in principle under the competence of the State in which the vessel is registered, the "flag State". Under the cabotage regulation, however, the Member States may impose their own rules regarding crews, "host State" rules, to vessels registered in another Member State that provides insular cabotage services on their territory. Greece considers the host State is competent for determining the number of sailors on board ships. The Commission, however, considers that such a condition excessively restricts the free provision of services. Furthermore, the Commission and Greece disagree over the crew regulations applicable to cruise vessels practising cabotage between islands.
