"Whilst this ancient corroborative jurisdiction survives, I shall scrupulously and rigorously enforce it where I can. Nevertheless, despite this reluctance to curtail my jurisdiction, I consider to exercise these powers would be wrong and I cannot justify what would be a devious entry to the court by the back door where Parliament has so firmly shut the front door to custody orders being made in these circumstances."
"The courts of this jurisdiction should be extremely circumspect in assuming any jurisdiction in relation to children physically present in some other jurisdiction founded only on the basis of nationality. Parens patriae jurisdiction has a fine resounding history. However, its practical significance has been much diminished domestically since the codification of much child law within theChildren Act 1989 in order to achieve essential collaboration internationally. It has been necessary to relax reliance upon concepts understood only in common law circles. Thus our historic emphasis on the somewhat artificial concept of domicile has had to cede to an acknowledgement that the simpler fact-based concept of habitual residence must be the currency of international exchange. The parens patriae concept must seem ever more esoteric to other jurisdictions than the concept of domicile. If we are to look for reciprocal understanding and co-operation, so vital are the steady increase in mobility and mixed marriage together with an equal decrease in the significance of international frontiers, we must refrain from exorbitant jurisdictional claims founded on nationality. To make a declaration of unlawful detention in relation to a child of dual nationality, cared for by a biological parent in a jurisdiction whose courts have sanctioned the arrangement by order is only to invite incomprehension and perhaps even stronger reactions in that other jurisdiction."
"Quite generally I do not think a child's ordinary residence [for that read habitual residence] can be changed by one parent without the consent of the other. It will not be changed until the parent who is left at home childless acquiesces in the change or delays so long in bringing proceedings that he or she must be taken to acquiesce. Six months delay would, I should have thought, go far to show acquiescence. Even three months might in some circumstances, but not less."
"If parents were together the habitual residence of the child is that of the parents unless there was a contrary agreement. One parent could not unilaterally change the child's habitual residence without the agreement of the other unless circumstances arose which quite independently pointed to a change in the child's habitual residence. It was open to the parents to agree to change their child's habitual residence without changing their own, but an agreement to send a child abroad to a boarding school is not sufficient."
"Additionally, and again in my judgment correctly, it was accepted that if the mother is to succeed I must find that consent was real in the sense that it was not based on a misunderstanding or non-disclosure which would vitiate the consent for the purposes of the Hague Convention. It is not sensible for me to try and give a general definition of what would constitute such a misunderstanding or non-disclosure. For the purposes of this case, in my judgment, such a misunderstanding or non-disclosure, and thus deception asserted by the father, would exist if the mother knew that the father was proceeding on the basis of a misunderstanding or she had not told him something and in either case he knew or ought to have known that such a misunderstanding or non-disclosure would, or would be likely to, affect the father's decision to consent to her taking H to England, whether that consent was given on the basis she alleges or on the basis that the father alleges. In such circumstances the mother could not believe, as she asserts, that the father had unequivocally consented to her taking H to England on 2 May on the basis that he would make his home here."
"In the case of the wrongful removal or retention of a child, the courts of the Member State where the child was habitually resident immediately before the wrongful removal or retention shall retain their jurisdiction until the child has acquired an habitual residence in another Member State."
"In cases of wrongful removal or retention of a child, the return of the child should be obtained without delay and to this end the Hague Convention of25 October 1980 would continue to apply as complimented by the provisions of this regulation, and in particular Article 11."
"Where a person or institution or other body having rights of custody applies to the competent authorities in the Member State to deliver a judgment on the basis of the Hague Convention on the civil aspects of international child abduction in order to obtain the return of a child that has been wrongfully removed or retained in a Member State, other than the Member State where the child was habitually resident immediately before the wrongful removal or retention, paragraphs 2-8 shall apply."
