Article 7
1 Upon being satisfied that the circumstances so warrant, any State Party in the territory of which the offender or the alleged offender is present shall, in accordance with its law, take him into custody or take other measures to ensure his presence for such time as is necessary to enable any criminal or extradition proceedings to be instituted.
2 Such State shall immediately make a preliminary inquiry into the facts, in accordance with its own legislation.
3 Any person regarding whom the measures referred to in paragraph 1 are being taken shall be entitled to:
(a) communicate without delay with the nearest appropriate representative of the State of which he is a national or which is otherwise entitled to establish such communication or, if he is a stateless person, the State in the territory of which he has his habitual residence;
(b) be visited by a representative of that State.
4 The rights referred to in paragraph 3 shall be exercised in conformity with the laws and regulations of the State in the territory of which the offender or the alleged offender is present, subject to the proviso that the said laws and regulations must enable full effect to be given to the purposes for which the rights accorded under paragraph 3 are intended.
5 When a State Party, pursuant to this article, has taken a person into custody, it shall immediately notify the States which have established jurisdiction in accordance with article 6, paragraph 1 and, if it considers it advisable, any other interested States, of the fact that such person is in custody and of the circumstances which warrant his detention. The State which makes the preliminary inquiry contemplated in paragraph 2 of this article shall promptly report its findings to the said States and shall indicate whether it intends to exercise jurisdiction.
