Article 9
Safeguard clauses
1. Where a State Party takes measures against a vessel in accordance with article 8 of this Protocol, it shall:
(a) Ensure the safety and humane treatment of the persons on board;
(b) Take due account of the need not to endanger the security of the vessel or its cargo;
(c) Take due account of the need not to prejudice the commercial or legal interests of the flag State or any other interested State;
(d) Ensure, within available means, that any measure taken with regard to the vessel is environmentally sound.
2. Where the grounds for measures taken pursuant to article 8 of this Protocol prove to be unfounded, the vessel shall be compensated for any loss or damage that may have been sustained, provided that the vessel has not committed any act justifying the measures taken.
3. Any measure taken, adopted or implemented in accordance with this chapter shall take due account of the need not to interfere with or to affect:
(a) The rights and obligations and the exercise of jurisdiction of coastal States in accordance with the international law of the sea; or
(b) The authority of the flag State to exercise jurisdiction and control in administrative , technical and social matters involving the vessel.
4. Any measure taken at sea pursuant to this chapter shall be carried out only by warships or military aircraft, or by other ships or aircraft clearly marked and identifiable as being on government service and authorized to that effect.
(43) 起草の過程では、この後の項に、他国の領海内では、沿岸国の許可のない限り、この章による措置は実行できない旨の規定を入れることも提案されたが、最終案には盛り込まれなかった。See UN, A/AC. 254/Add. 1/Rev. 6, Article 7 ter.それは、国連海洋法条約をはじめとする海洋に関する国際法上、確立した原則であって、わざわざ規定することはないと考えられたためである。See UN, A/55/383/Add. 1, para. 98.
