4. A State Party shall respond expeditiously to a request from another State Party to determine whether a vessel that is claiming its registry or flying its flag is entitled to do so and to a request for authorization made in accordance with paragraph 2 of this article.
5. A flag State may, consistent with article 7 of this Protocol, subject its authorization to conditions to be agreed by it and the requesting State, including conditions relating to responsibility and the extent of effective measures to be taken. A State Party shall take no additional measures without the express authorization of the flag State, except those necessary to relieve imminent danger to the lives of persons or those which derive from relevant bilateral or multilateral agreements.
6. Each State Party shall designate an authority or, where necessary, authorities to receive and respond to requests for assistance, for confirmation of registry or of the right of a vessel to fly its flag and for authorization to take appropriate measures. Such designation shall be notified through the Secretary-General to all other States Parties within one month of the designation.
7. A State Party that has reasonable grounds to suspect that a vessel is engaged in the smuggling of migrants by sea and is without nationality or may be assimilated to a vessel without nationality may board and search the vessel. If evidence confirming the suspicion is found, that State Party shall take appropriate measures in accordance with relevant domestic and international law.
