14 MEDVEDYEV AND OTHERS v. FRANCE JUDGMENT Article 11 – Execution of action 1. Actions taken under Articles 9 and 10 shall be governed by the law of the intervening State ...” E. Agreement Concerning Cooperation in Suppressing Illicit Maritime and Air Trafficking in Narcotic Drugs and Psychotropic Substances in the Caribbean Area, signed at San José on 10 April 2003 31. This agreement between continental and island States of the Caribbean area (Costa Rica, the Dominican Republic, France, Guatemala, Haiti, Honduras, the Netherlands, Nicaragua and the United States of America) in respect of the Vienna Convention, lays down the conditions of the battle against trafficking in narcotic drugs in the area by introducing broad cooperation and providing for States to be able to consent in advance to intervention by the other States Parties on ships flying their flags. 32. It allows a State Party to take coercive action, even in the territorial waters of another State Party, by delegation of the latter State. There are three possibilities: – systematic authorisation; – authorisation if no answer is received from the flag State within four hours of another Party submitting a request for intervention; – express authorisation for the intervention, which corresponds to the current legal situation under the Vienna Convention. 33. The draft law thus allows the States to consent in advance to the intervention of other Parties on a ship flying their flag or located within their territorial waters. F.
