1. Having received the authorisation of the flag State, and subject to the conditions or limitations, if any, made under Article 8, paragraph 1, the intervening State may take the following actions:
   1. 1. stop and board the vessel;
      2. establish effective control of the vessel and over any person thereon;

2. Any action taken under paragraph 1 of this article shall be without prejudice to any right existing under the law of the intervening State of suspected persons not to incriminate themselves.

Article 10 – Enforcement measures

1. Where, as a result of action taken under Article 9, the intervening State has evidence that a relevant offence has been committed which would be sufficient under its laws to justify its either arresting the persons concerned or detaining the vessel, or both, it may so proceed.
2. The intervening State shall, without delay, notify the flag State of steps taken under paragraph 1 above.
3. The vessel shall not be detained for a period longer than that which is strictly necessary to complete the investigations into relevant offences.

Persons not suspected of any relevant offence and objects not required as evidence shall be released.
4. Notwithstanding the provisions of the preceding paragraph, the intervening State and the flag State may agree with a third State, Party to this Agreement, that the vessel may be taken to the territory of that third State and, once the vessel is in that territory, the third State shall be treated for the purposes of this Agreement as an intervening State.

Article 11 – Execution of action

1. Actions taken under Articles 9 and 10 shall be governed by the law of the intervening State.

   2. the need to minimise any interference with the legitimate commercial activities of a vessel;
   3. the need to avoid unduly detaining or delaying a vessel;
   4. the need to restrict the use of force to the minimum necessary to ensure compliance with the instructions of the intervening State.
2. The use of firearms against, or on, the vessel shall be reported as soon as possible to the flag State.

The flag State sh
   all acknowledge receipt of the summary forthwith.
2. If the intervening State discovers evidence which leads it to believe that offences outside the scope of this Agreement may have been committed, or that suspect persons not involved in relevant offences are on board the vessel, it shall notify the flag State. Where appropriate, the Parties involved shall consult.
3. The provisions of this Agreement shall be so construed as to permit the intervening State to take measures, including the detention of persons, other than those aimed at the investigation and prosecution of relevant offences, only when:
   1. the flag State gives its express consent; or
   2. such measures are aimed at the investigation and prosecution of an offence committed after the person has been taken into the territory of the intervening State.

Article 14 – Exercise of preferential jurisdiction

1. A flag State wishing to exercise its preferential jurisdiction shall do so in accordance with the provisions of this article.
2. It shall notify the intervening State to this effect as soon as possible and at the latest within fourteen days from the receipt of the summary of evidence pursuant to Article 13. If the flag State fails to do this, it shall be deemed to have waived the exercise of its preferential jurisdiction.

4. The flag State shall submit the case forthwith to its competent authorities for the purpose of prosecution.
5. Measures taken by the intervening State against the vessel and persons on board may be deemed to have been taken as part of the procedure of the flag State.

The request for the surrender of arrested persons shall be supported by, in respect of each person, the original or a certified copy of the warrant of arrest or other order having the same effect, issued by a judicial authority in accordance with the procedure prescribed by the law of the flag State.
3. The Parties shall use their best endeavours to expedite the surrender of persons, vessels, cargoes and evidence.
4. Nothing in this Agreement shall be so construed as to deprive any detained person of his right under the law of the intervening State to have the lawfulness of his detention reviewed by a court of that State, in accordance with procedures established by its national law.
5. Instead of requesting the surrender of the detained persons or of the vessel, the flag State may request their immediate release. Where this request has been made, the intervening State shall release them forthwith.

Article 16 – Capital punishmentIf any offence for which the flag State decides to exercise its preferential jurisdiction in accordance with Article 14 is punishable by death under the law of that State, and if in respect of such an offence the death penalty is not provided by the law of the intervening State or is not normally carried out, the surrender of any person may be refused unless the flag State gives such assurances as the intervening State considers sufficient that the death penalty will not be carried out.Section 5 – Procedural and other general rulesArticle 17 – Competent authorities
