punish the international traffic in minors defined in this Convention. Article 8 The States Parties to the present Convention undertake to: a) assist each other promptly and expeditiously through their Central Authorities, as permitted by the domestic laws of each State and by applicable international treaties, to conduct judicial and administrative proceedings, to take evidence, and to take any other procedural steps that may be necessary for fulfilling the objectives of this Convention; b) establish through their Central Authorities mechanisms for the exchange of information about any domestic statute, case law, administrative practices, statistics and modalities regarding international traffic in minors in their States; and c) order such measures as may be necessary to remove any obstacles that might affect the enforcement of this Convention in their States. Article 9 The following shall have competence in cases of crimes involving international traffic in minors: a) the State Party where the wrongful conduct occurred; b) the State Party that is the habitual residence of the minor; c) the State Party in which the alleged offender is located if said offender has not been extradited. d) the State Party in which the minor who is a victim of said traffic is located. For the purposes of the preceding paragraph, the State Party that first conducted formal proceedings concerning the wrongful act shall have preference. Article 10 If one of the States Parties where extradition is subject to the existence of a treaty receives a request for extradition from a State Party with which it has no such treaty, or if it has such a treaty, this crime is not among the extraditable offenses, it may consider the present Convention as the legal grounds needed to grant extradition in the case of the international traffic in minors. Further, States Parties that do not make extradition conditional on the existence of a treaty shall recognize the international traffic in minors as a basis for extradition between them. Where no extradition treaty exists, extradition shall be subject to the other conditions required by the domestic laws of the requested State. Article 11 The actions taken in accordance with the provisions of this chapter shall not prevent the competent authorities of the State Party where the minor is located from ordering, at any time, said minor's immediate return to the State of his or her habitual residence, bearing in mind the best interests of the minor.
