"Article 1 (1) The objects of the present Convention are – a) to determine the State whose authorities have jurisdiction to take measures directed to the protection of the person or property of the child; b) to determine which law is to be applied by such authorities in exercising their jurisdiction; c) to determine the law applicable to parental responsibility; d) to provide for the recognition and enforcement of such measures of protection in all Contracting States; e) to establish such co-operation between the authorities of the Contracting States as may be necessary in order to achieve the purposes of this Convention. (2) For the purposes of this Convention, the term 'parental responsibility' includes parental authority, or any analogous relationship of authority determining the rights, powers and responsibilities of parents, guardians or other legal representatives in relation to the person or the property of the child."
“Article 5 (1) The judicial or administrative authorities of the Contracting State of the habitual residence of the child have jurisdiction to take measures directed to the protection of the child's person or property. (2) Subject to Article 7, in case of a change of the child's habitual residence to another Contracting State, the authorities of the State of the new habitual residence have jurisdiction.”
“[87] Where then does this plethora of authority on the concept of habitual residence leave the busy judge who is required to determine the preliminary issue of jurisdiction, without that determination “becoming an unworkable obstacle course, through which the judge must pick his or her way by a prescribed route or risk being said to have made an unsustainable finding?”
“Article 7 (1) In case of wrongful removal or retention of the child, the authorities of the Contracting State in which the child was habitually resident immediately before the removal or retention keep their jurisdiction until the child has acquired a habitual residence in another State, and a) each person, institution or other body having rights of custody has acquiesced in the removal or retention; or b) the child has resided in that other State for a period of at least one year after the person, institution or other body having rights of custody has or should have had knowledge of the whereabouts of the child, no request for return lodged within that period is still pending, and the child is settled in his or her new environment. (2) The removal or the retention of a child is to be considered wrongful where - a) it is in breach of rights of custody attributed to a person, an institution or any other body, either jointly or alone, under the law of the State in which the child was habitually resident immediately before the removal or retention; and b) at the time of removal or retention those rights were actually exercised, either jointly or alone, or would have been so exercised but for the removal or retention. The rights of custody mentioned in sub-paragraph a above, may arise in particular by operation of law or by reason of a judicial or administrative decision, or by reason of an agreement having legal effect under the law of that State. (3) So long as the authorities first mentioned in paragraph 1 keep their jurisdiction, the authorities of the Contracting State to which the child has been removed or in which he or she has been retained can take only such urgent measures under Article 11 as are necessary for the protection of the person or property of the child.”
“Article 8 (1) By way of exception, the authority of a Contracting State having jurisdiction under Article 5 or 6, if it considers that the authority of another Contracting State would be better placed in the particular case to assess the best interests of the child, may either - request that other authority, directly or with the assistance of the Central Authority of its State, to assume jurisdiction to take such measures of protection as it considers to be necessary, or - suspend consideration of the case and invite the parties to introduce such a request before the authority of that other State. (2) The Contracting States whose authorities may be addressed as provided in the preceding paragraph are a) a State of which the child is a national, b) a State in which property of the child is located, c) a State whose authorities are seised of an application for divorce or legal separation of the child's parents, or for annulment of their marriage, d) a State with which the child has a substantial connection. (3) The authorities concerned may proceed to an exchange of views. (4) The authority addressed as provided in paragraph 1 may assume jurisdiction, in place of the authority having jurisdiction under Article 5 or 6, if it considers that this is in the child's best interests.”
"[24] The test for transfer under Art 8(1) is whether the other Contracting State is better placed to assess the best interests of the child. Where the Contracting State with jurisdiction is better placed to assess the best interests of the child, or where the Contracting States are equally well placed to assess the best interests, the Art 8(1) test will not be made out and jurisdiction will remain with Contracting State having jurisdiction. [25] The Practical Handbook on the Operation of the 1996 Hague Child Protection Convention at paragraph 5.9 makes clear that a transfer under Art 8 may only be effected when three conditions are satisfied. First, that there is a connection between the child and the Contracting State to whose authorities it is permissible to transfer jurisdiction. Art 8(2) provides an exhaustive list of the factors capable of demonstrating such a connection. Second, the transfer must be in the child's best interests. Third, both Contracting States must agree to the transfer of jurisdiction. With respect to the best interests criteria, the Practical Handbook further observes as follows: 'The authority making the request that jurisdiction be transferred must consider that this will allow for a better assessment of the child's best interests. The authority asked to assume or cede jurisdiction can only do so if it believes this is in the child's best interests.' [26] Art 8(1) of the 1996 Hague Convention states expressly that the power to transfer jurisdiction under Art 8 is to be applied by way of an exception and, accordingly, represents an exception to the general rule of jurisdiction set out in Art 5. Further, the wording of Art 8(1) makes clear that even where the court concludes that the authority of another Contracting State would be better placed in the particular case to assess the best interests of the child, the court with jurisdiction retains a discretion as to whether to effect that transfer and is not obliged to do so."
“…must be understood as favouring a flexible interpretation of the terms used, which allows the greatest possible number of cases to be brought into consideration.”
“[69] The second source of custody rights contained in article 3 is a judicial or administrative decision. Since the Convention does not expand upon this, it must be deemed, on the one hand, that the word 'decision' is used in its widest sense, and embraces any decision or part of a decision (judicial or administrative) on a child's custody and, on the other hand, that these decisions may have been issued by the courts of the State of the child's habitual residence as well as by the courts of a third country.”
“[60] Accordingly on this aspect of the case, we conclude that (1) the Hague Convention requires the Court to give the expression "rights of custody" an autonomous interpretation; (2) the reference in article 3 to "rights of custody attributed to a person … under the law" of the child's habitual residence is not a choice of law of that state in the sense that if the domestic law, still less the conflict of laws rule, does not characterise the right as a right of custody, then it will not be such a right for Hague Convention purposes; (3) the task of the Court is to establish the rights of the parents under the law of that state and then to consider whether those rights are rights of custody for Hague Convention purposes; (4) in considering whether those rights are rights of custody, the Court is entitled and bound to give a purposive and effective interpretation to the Hague Convention; (5) the rights given by the New York order to the father are rights of custody D for Hague Convention purposes, whether or not New York state or federal law so regards them either for domestic purposes or Hague Convention purposes.”
“Having made what is no more than an interim custody order, the Ontaria court, in my judgment, retained what article 5(a) of the Convention calls “the right to determine the child’s place of residence.”
“That sentence seems to me to encapsulate the ratio decidendi in B v B, namely, that as an interim custody order had been made, so rights of custody remain in the court. That case must be the high water mark of any submission of this nature and the basis of the decision was that the court had made an interim custody order. No such order has been made in the present case. For my part, I do not think that that case or the other cases relied upon by Mr Levy can be stretched to the extent of the court making a finding that the issue of proceedings in the Willesden County Court or the High Court vested rights of custody either in the father or in either of those courts.”
“In this case, however, there is no doubt that the W. children were habitually resident in England and Wales before their removal to Australia. As already seen, the purpose of the Hague Convention of 1980 is to secure that children are returned so that the merits of decisions concerning their custody can be determined in the courts of the country where they are habitually resident. There is something particularly repugnant about a litigant seeking to frustrate the processes of the law in this way. This emboldens me to conclude that the removal of the W. children was wrongful within the meaning of the Convention because it was in breach of rights of custody attributable to the court.”
“There are two aspects to this matter. First of all the application to the court must raise matters of custody within the meaning of the Convention and that will require in every case a consideration of the terms of the application. Secondly, a question arises as to the time at which the court acquires such right. It is clear that the interpretation which has been accepted of the Convention which allows the possibility of a court having rights of custody does not contemplate that happening unless there is an application to the court in a particular case raising the issue of the custody of one or more children. The date at which such application confers these rights is a matter which has not been the subject of detailed consideration in relation to the Convention. For the purposes of theCivil Jurisdiction and Judgments Act 1982 , Schedule 1, article 21 and the 1968 Brussels Convention on Jurisdiction and the Enforcement of Judgments in Civil and Commercial Matters which is scheduled to that Act (Schedule 1) it has been held that an English court becomes definitively seized of proceedings for the purposes of that Convention on the date of service of the writ at which point it has jurisdiction over the merits of the dispute: Neste Chemicals S.A. v. D.K. Line S.A. [1994] 3 All E.R. 180 and Dresser U.K. Ltd. v. Falcongate Freight Management Ltd [1992] Q.B. 502. In relation to the present Convention while in the wardship jurisdiction the issue of an application makes the child who was the subject of the application a ward of court I consider that generally speaking there is much force in using the service of the application as the time at which the court's jurisdiction is first invoked. It is true that interim orders may be made before service and special cases may arise but generally speaking I would think it a reasonable rule that at the latest when the proceedings have been served the jurisdiction has been invoked and unless the proceedings are stayed or some equivalent action has been taken I would treat the court's jurisdiction as being continuously invoked thereafter until the application is disposed of.”
“The underlying idea is that the person who makes a wrongful removal should not be able to take advantage of this act in order to modify for his or her benefit the jurisdiction of the authorities called upon to take measures of protection for the person, or even the property, of the child. But, on the other hand, the wrongful removal, if it persists, is a fact that cannot be ignored to such a point as to deprive the authorities of the new State, which has become that of the new habitual residence of the child, of this jurisdiction over protection. The difficulty consists therefore in determining the temporal threshold from which jurisdiction would pass from the authorities of the State from which the child has been wrongfully removed, to those of the country to which he or she has been taken or in which he or she has been retained.”
“it is acquiescence in the wrongful removal which triggers, if it is added to the other conditions required, the disappearance of the jurisdiction of the authorities of the child’s former habitual residence…”
“In my judgment, therefore, in the ordinary case the court has to determine whether in all the circumstances of the case the wronged parent has, in fact, gone along with the wrongful abduction. Acquiescence is a question of the actual subjective intention of the wronged parent, not of the outside world's perception of his intentions.”
“My Lords, in my judgment these exceptional circumstances can only arise where the words or actions of the wronged party show clearly and unequivocally that the wronged parent is not insisting on the summary return of the child: they must be wholly inconsistent with a request for the summary return of the child.”
“…that authority, and authorities generally on the topic of acquiescence, are concerned with acquiescence by the left behind parent. It seems to me that a rather different approach has to be taken to acquiescence in the case of a court of competent jurisdiction in the state of habitual residence.”
