In the event of exceptional events having the effect of temporarily interrupting maritime relations reserved for ships operated by shipowners who are nationals of a Member State of the European Community or of a State party to the Agreement on the European Economic Area, registered in a Member State of the European Community or in another State party to the Agreement on the European Economic Area and flying the flag of that same State, the Government may suspend the application of article 257 by decree deliberated in the Council of Ministers after consultation with the Council of State, and for as long as the suspension lasts, and thus authorise ships flying the flag of a State other than those mentioned above to carry out transport between ports in mainland France.
The return to the normal regime is pronounced in the same form as soon as circumstances allow.
