20The provisions of this Chapter apply even if the law designated by them is the law of a non-Contracting State.Article 211. In this Chapter the term "law" means the law in force in a State other than its choice of law rules.2. However, if the law applicable according to Article 16 is that of a non-Contracting State and if the choice of law rules of that State designate the law of another non-Contracting State which would apply its own law, the law of the latter State applies. If that other non-Contracting State would not apply its own law, the applicable law is that designated by Article 16.Article 22The application of the law designated by the provisions of this Chapter can be refused only if this application would be manifestly contrary to public policy, taking into account the best interests of the child.CHAPTER IVRECOGNITION AND ENFORCEMENTArticle 231. The measures taken by the authorities of a Contracting State shall be recognised by operation of law in all other Contracting States.2. Recognition may however be refused:(a) if the measure was taken by an authority whose jurisdiction was not based on one of the grounds provided for in Chapter II;b) if the measure was taken, except in a case of urgency, in the context of a judicial or administrative proceeding, without the child having been provided the opportunity to be heard, in violation of fundamental principles of procedure of the requested State;(c) on the request of any person claiming that the measure infringes his or her parental responsibility, if such measure was taken, except in a case of urgency, without such person having been given an opportunity to be heard;(d) if such recognition is manifestly contrary to public policy of the requested State, taking into account the best interests of the child;(e) if the measure is incompatible with a later measure taken in the non-Contracting State of the habitual residence of the child, where this later measure fulfils the requirements for recognition in the requested State;(f) if the procedure provided in Article 33 has not been complied with.Article 24Without prejudice to Article 23(1), any interested person may request from the competent authorities of a Contracting State that they decide on the recognition or non-recognition of a measure taken in another Contracting State. The procedure is governed by the law of the requested State.Article 25The authority of the requested State is bound by the findings of fact on which the authority of the State where the measure was taken based its jurisdiction.Article 261. If measures taken in one Contracting State and enforceable there require enforcement in another Contracting State, they shall, upon request by an interested party, be declared enforceable or registered for the purpose of enforcement in that other State according to the procedure provided in the law of the latter State.2. Each Contracting State shall apply to the declaration of enforceability or registration a simple and rapid procedure.3. The declaration of enforceability or registration may be refused only for one of the reasons set out in Article 23(2).Article 27Without prejudice to such review as is necessary in the application of the preceding Articles, there shall be no review of the merits of the measure taken.Article 28Measures taken in one Contracting State and declared enforceable, or registered for the purpose of enforcement, in another Contracting State shall be enforced in the latter State as if they had been taken by the authorities of that State. Enforcement takes place in accordance with the law of the requested State to the extent provided by such law, taking into consideration the best interests of the child.CHAPTER VCOOPERATIONArticle 291. A Contracting State shall designate a Central Authority to discharge the duties which are imposed by the Convention on such authorities.2. Federal States, States with more than one system of law or States having autonomous territorial units shall be free to appoint more than one Central Authority and to specify the territorial or personal extent of their functions. Where a State has appointed more than one Central Authority, it shall designate the Central Authority to which any communication may be addressed for transmission to the appropriate Central Authority within that State.Article 301. Central Authorities shall cooperate with each other and promote cooperation amongst the competent authorities in their States to achieve the purposes of the Convention.2. They shall, in connection with the application of the Convention, take appropriate steps to provide information as to the laws of, and services available in, their States relating to the protection of children.Article 31The Central Authority of a Contracting State, either directly or through public authorities or other bodies, shall take all appropriate steps to:(a) facilitate the communications and offer the assistance provided for in Articles 8 and 9 and in this Chapter;(b) facilitate, by mediation, conciliation or similar means, agreed solutions for the protection of the person or property of the child in situations to which the Convention applies;(c) provide, on the request of a competent authority of another Contracting State, assistance in discovering the whereabouts of a child where it appears that
