‘First, as to para [73] of his judgment and to the reference that an agreement to take the children ‘to another country for a temporary purpose, in particular that of education, will not alone be sufficient to change their habitual residence'. The context is clear. The President was referring to the judgment of this court in Re M upon which Mr Blake, who then appeared for the mother, was relying (see para [71] of the President's judgment). The President was not saying that a visit for a temporary purpose could never establish habitual residence. On the contrary, he was saying, correctly, that ‘such an agreement is one of the main facts or circumstances to be taken into account'.’
“Drawing the threads together, therefore: i. All are agreed that habitual residence is a question of fact and not a legal concept such as domicile. There is no legal rule akin to that whereby a child automatically takes the domicile of his parents. ii. It was the purpose of the 1986 Act to adopt a concept which was the same as that adopted in the Hague and European Conventions. The Regulation must also be interpreted consistently with those Conventions. iii. The test adopted by the European Court is "the place which reflects some degree of integration by the child in a social and family environment" in the country concerned. This depends upon numerous factors, including the reasons for the family's stay in the country in question. iv. It is now unlikely that that test would produce any different results from that hitherto adopted in the English courts under the 1986 Act and the Hague Child Abduction Convention. v. In my view, the test adopted by the European Court is preferable to that earlier adopted by the English courts, being focussed on the situation of the child, with the purposes and intentions of the parents being merely one of the relevant factors. The test derived from R v Barnet London Borough Council, ex p Shah should be abandoned when deciding the habitual residence of a child. vi. The social and family environment of an infant or young child is shared with those (whether parents or others) upon whom he is dependent. Hence it is necessary to assess the integration of that person or persons in the social and family environment of the country concerned. vii. The essentially factual and individual nature of the inquiry should not be glossed with legal concepts which would produce a different result from that which the factual inquiry would produce. viii. As the Advocate General pointed out in para AG45 and the court confirmed in para 43 of Proceedings brought by A, it is possible that a child may have no country of habitual residence at a particular point in time”
“An infant necessarily shares the social and family environment of the circle of people on whom he or she is dependent. Consequently, where . . . the infant is in fact looked after by her mother, it is necessary to assess the mother’s integration in her social and family environment. In that regard, the tests stated in the court’s case law, such as the reasons for the move by the child’s mother to another member state, the languages known to the mother or again her geographic and family origins may become relevant.” 21. Several further points can be taken from A v A. There is no legal rule, akin to that in the law of domicile, that a child automatically takes the habitual residence of his parents. The proposition of Lord Brandon of Oakbrook in In re J (A Minor) (Abduction: Custody Rights)[1990] 2 AC 562 , that a young child in the sole lawful custody of his mother will necessarily have the same habitual residence as she does, is to be regarded as a helpful generalisation of fact, which will usually but not invariably be true, rather than a proposition of law (see A v A, paras 44 and 73). As Lord Hughes pointed out, Lord Brandon cannot have intended it as such without destroying his first proposition, which was that habitual residence is a question of fact, to be decided in the light of all the circumstances. 22. Both Lord Hughes and I also questioned whether it was necessary to maintain the rule, hitherto firmly established in English law, that (where both parents have equal status in relation to the child) one parent could not unilaterally change the habitual residence of a child (see In re S (Minors) (Child Abduction: Wrongful Retention)[1994] Fam 70 , approved by the Court of Appeal in Re M (Abduction: Habitual Residence)[1996] 1 FLR 887 ). As the US Court of Appeals for the Ninth Circuit pointed out in, In re the application of Mozes, 239 F 3d 1067 (9th Cir 2001), at 1081, such a bright line rule certainly furthers the policy of discouraging child abductions, but if not carefully qualified it is capable of leading to absurd results (referring to EM Clive, “The Concept of Habitual Residence” [1997] Juridical Review 137, at 145). The court continued: “Habitual residence is intended to be a description of a factual state of affairs, and a child can lose its [sic] habitual attachment to a place even without a parent’s consent. Even when there is no settled intent on the part of the parents to abandon the child’s prior habitual residence, courts should find a change in habitual residence if ‘the objective facts point unequivocally to a person’s ordinary or habitual residence being in a particular place’ [referring to the Scottish case of Zenel v Haddow 1993 SLT 975].” 23. Nevertheless, it is clear that parental intent does play a part in establishing or changing the habitual residence of a child: not parental intent in relation to habitual residence as a legal concept, but parental intent in relation to the reasons for a child’s leaving one country and going to stay in another. This will have to be factored in, along with all the other relevant factors, in deciding whether a move from one country to another has a sufficient degree of stability to amount to a change of habitual residence.”
