“(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. BIIR 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 focused on the situation of the child, with the purposes and intentions of the parents being merely one of the relevant factors. The test derived fromShahshould 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 Re A (Area of Freedom, Security and Justice), it is possible that a child may have no country of habitual residence at a particular point in time.”
“…It is the child’s habitual residence which is under consideration. Each child is an individual with his own experiences and his own perceptions…where parents are separated, there may well be two possible homes in which the children can live and the children will be well aware of this. This may well affect the degree of their integration in a new environment. The quality of a child’s stay in a new environment, in which he has only recently arrived, cannot be assessed without reference to the past. Some habitual residences may be harder to lose than others and others may be harder to gain. If a person leaves his home country with the intention of emigrating and having made all the necessary plans to do so, he may lose one habitual residence immediately and acquire a new one very quickly. If a person leaves his home country for a temporary purpose or in ambiguous circumstances, he may not lose his habitual residence there for some time, if at all, and correspondingly he will not acquire a new habitual residence until then or even later…”
“I conclude that the modern concept of a child’s habitual residence operates in such a way as to make it highly unlikely, albeit conceivable, that a child will be in the limbo in which the courts below have placed B. The concept operates in the expectation that, when a child gains a new habitual residence, he loses his old one. Simple analogies are best: consider a see-saw. As, probably quite quickly, he puts down those first roots which represent the requisite degree of integration in the environment of the new state, up probably come the child’s roots in that of the old state to the point at which he achieves the requisite de-integration (or, better, disengagement) from it. … The identification of a child’s habitual residence is overarchingly a question of fact. In making the following three suggestions about the point at which habitual residence might be lost and gained, I offer not sub rules but expectations which the fact-finder may well find to be unfulfilled in the case before him: (a) the deeper the child’s integration in the old state, probably the less fast his achievement of the requisite degree of integration in the new state; (b) the greater the amount of adult pre-planning of the move, including pre-arrangements for the child’s day-to-day life in the new state, probably the faster his achievement of that requisite degree; and (c) were all the central members of the child’s life in the old state to have moved with him, probably the faster his achievement of it, and, conversely, were any of them to have remained behind and thus to represent for him a continuing link with the old state, probably the less fast his achievement of it.” (a) the deeper the child’s integration in the old state, probably the less fast his achievement of the requisite degree of integration in the new state; (b) the greater the amount of adult pre-planning of the move, including pre-arrangements for the child’s day-to-day life in the new state, probably the faster his achievement of that requisite degree; and (c) were all the central members of the child’s life in the old state to have moved with him, probably the faster his achievement of it, and, conversely, were any of them to have remained behind and thus to represent for him a continuing link with the old state, probably the less fast his achievement of it.”
