“… I certainly cannot accept that permanence is necessary to establish habitual residence. “A certain permanence”, whatever that may be, can be understood as connoting the features of “settled purpose” as used in Shah, and so understood as acceptable. Strictly speaking the decision in Mercredi v Chaffe and the earlier decision of the European Court of Justice, Re A (Area of Freedom, Security and Justice) (Case C-523/07 ),[2009] 2 FLR 1 do not apply here: those cases concern Brussels II Revised as it applied within the European Union. Here the contesting states are Australia and the United Kingdom. I have no doubt however, that, at least in the fullness of time, the European meaning of habitual residence will by osmosis shape the autonomous meaning to be given to that phrase in the International Hague Convention on Child Abduction with the stress on its international application. But I would sound another note of caution. In para 51 of Mercredi v Chaffe, the Court of Justice of the European Union states: “In order to distinguish habitual residence from mere temporary residence, the former must as a general rule have a certain duration which reflects an adequate degree of permanence.”
“… Before habitual residence can be transferred to the host State, it is of paramount importance that the person concerned has it in mind to establish there the permanent or habitual centre of his interests, with the intention that it should be of a lasting character.”
“I do not regard Lord Brandon’s words as intending to suggest that the habitual residence of the child is that same as that of the parent who alone has parental responsibility, notwithstanding that the child may have been living apart from that parent for a period which may have lasted for several years. That would be inconsistent with the second point that habitual residence is a question for fact. All he was saying was that where a young child is in the physical care of a mother who alone has parental responsibility for a child, then normally the child’s habitual residence will be the same as hers, since it is her will that determines the element of volition involved in the concept of habitual residence”
“[62] I accept unreservedly the statement of principle that a child’s habitual residence does not change unless both of the parents create a change; for instance that they arrange for the child to live in settled circumstances abroad (such as at boarding school or placed with family); or themselves both move to a foreign jurisdiction for a settled purpose; and, most importantly in the context of this case, voluntarily. It is very important, as the Court of Appeal has subsequently stressed, not to elevate this test into a domicile or quasi domicile test because habitual residence is a question of fact. [63] In my view the reason why the consent, agreement, acquiescence, acceptance (however one may put it) of each of the parents is crucial is because of the requirement that the residence must be “voluntary” to be habitual. Also, I suppose, if it is not voluntary then it cannot be said to be settled.”
“The father’s consent to this arrangement although given reluctantly in the hope that it would have only a temporary effect was not at that stage qualified by any express condition or time limit.”
“In my view, it is important to recognise that what the father seeks to establish is that the children's place of habitual residence has changed. I have concluded that this cannot happen where he alone of the parents with whom they are living has lost the habitual residence that he shared with the mother and the children and become habitually resident elsewhere.”
“[46] … that where there has been an agreement - I will not call it a consent – for the mother and the child to move for a certain period of time, the court, as it did in Re K (Abduction: Consent: Forum Conveniens), is entitled to look at the question of whether or not mother and, more importantly, the children have acquired a new habitual residence.”
