(2) A ship required to hold a certificate in accordance with the pro- 

 visions of the Regulations is subject while in the ports or off-shore 

 terminals under the jurisdiction of a Party to inspection by officers 

 duly authorized by that Party. Any such inspection shall be limited 

 to verifying that there is on board a valid certificate, unless there are 

 clear grounds for believing that the condition of the ship or its equip- 

 ment does not correspond substantially with the particulars of that 

 certificate. In that case, or if the ship does not carry a valid certificate, 

 the Party carrying out the inspection shall take such steps as will 

 ensure that the ship shall not sail until it can proceed to sea w^ithout 

 presenting an unreasonable threat of harm to the marine environ- 

 ment. That Party may, however, grant such a ship permission to leave 

 the port or off-shore terminal for the purpose of proceeding to the 

 nearest appropriate repair yard available. 



(3) If a Party denies a foreign ship enty to the ports or off-shore 

 terminals under its jurisdiction or takes any action against such a 

 ship for the reason that the ship does not comply with the provisions 

 of the present Convention, the Party shall immediately inform the 

 consul or diplomatic representative of the Party whose flag the ship 

 is entitled to fly, or if this is not possible, the Administration of the 

 ship concerned. Before denying entry or taking such action the Party 

 may request consultation with the Administration of the ship con- 

 cerned. Information shall also be given to the Administration when 

 a ship does not carry a valid certificate in accordance with the pro- 

 visions of the Regulations. 



(4) With respect to the ships of non-Parties to the Convention, 

 Parties shall apply the requirements of the present Convention as may 

 be necessary to ensure that no more favourable treatment is given to 

 such ships.

 vention, using all appropriate and practicable measures of detection

(2) A ship to which the present Convention applies mav, in any 

 port or off-shore terminal of a Party, be subject to inspection by officers 

 appointed or authorized by that Party for the purpose of verifying 

 whether the ship has discharged any harmful substances in violation 

 of the provisions of the Regulations. If an inspection indicates a vio- 

 lation of the Convention, a report shall be forwarded to the Admin- 

 istration for any appropriate action. 



(3) Any Party shall furnish to the Administration evidence, if 

 any, that the ship has discharged harmful substances or effluents con- 

 taining such substances in violation of the provisions of the Regula- 

 tions. If it is practicable to do so, the competent authority of the 

 former Party shall notify the master of the ship of the alleged vio- 

 lation. 



(4) Upon receiving such evidence, the Administration so informed 

 shall investigate the matter, and may request the other Party to
