"to secure the prompt return of children wrongfully removed to or retained in any Contracting State." 22. As Mostyn J identified in B v B[2014] EWHC 1804 : "2. The Hague Convention of 1980 is arguably the most successful ever international treaty and it has over 90 subscribers to it, over half the countries in the world. The underlying and central foundation of the Convention is that, where a child has been unilaterally removed from the land of her habitual residence in breach of someone's rights of custody, then she should be swiftly returned to that country for the courts of that country to decide on her long-term future. 3. There are very few exceptions to this and the exceptions that do exist have to be interpreted very narrowly in order that the central premise of the Convention is not fatally undermined. It is important to understand what the Convention does not do. The Convention does not order a child who has been removed in the circumstances I have described to live with anybody. The Convention does not provide that the parent who is left behind should, on the return of the child, have contact or access in any particular way. The Convention does not provide that, when an order for return to the child's homeland is made, the child should stay there indefinitely. All the Convention provides is that the child should be returned for the specific purpose and limited period to enable the court of her homeland to decide on her long-term future. That is all it decides.” 23. The wrongfulness of a removal or retention is governed by Article 3, which provides that: "
"Where a child has been wrongfully removed or retained in terms of Article 3 and, at the date of the commencement of the proceedings before the judicial or administrative authority of the Contracting State where the child is, a period of less than one year has elapsed from the date of the wrongful removal or retention, the authority concerned shall order the return of the child forthwith."
"Notwithstanding the provisions of the preceding Article, the judicial or administrative authority of the requested State is not bound to order the return of the child if the person, institution or other body which opposes its return establishes that – (a) the person institution or other body having the care of the person of the child was not actually exercising the custody rights at the time of removal or retention, or had consented to or subsequently acquiesced in the removal or retention; or (b) there is a grave risk that his or her return would expose the child to physical or psychological harm or otherwise place the child in an intolerable situation."
“When the left-behind parent agrees to the child travelling abroad, he is exercising, not abandoning, his rights of custody. Those rights of custody include the right to be party to any arrangement as to which country the child is to live in. It is not accurate to say that he gives up a right to veto the child’s movements abroad; he exercises that right by permitting such movement on terms. He has agreed to the travel only on terms that the stay is to be temporary and the child will be returned as agreed. So long as the travelling parent honours the temporary nature of the stay abroad, he is not infringing the left-behind parent’s rights of custody. But once he repudiates the agreement, and keeps the child without the intention to return, and denying the temporary nature of the stay, his retention is no longer on the terms agreed. It amounts to a claim to unilateral decision where the child shall live. It repudiates the rights of custody of the left-behind parent and becomes wrongful.”
“…it seems to me that there must be some ingredient to indicate that the departure from one country to another is intended to be temporary rather than permanent or potentially permanent, even if the precise date of return is not fixed. Thus, it is hard to conceive of a wrongful retention where the departure from the outward country is agreed to be open ended with no determining or triggering event… In each case, the court will have to do the best it can on the available information to determine the relevant date.”
"If a left-behind parent with rights of custody gave consent, by which I therefore mean prior consent, to the child's removal, how can he successfully complain that it was in breach of his rights within the meaning ofarticle 3 of the Convention ? There is no good answer to this question. So the poor draftsmanship of the Convention gives rise to a conundrum: although Art 13 expressly suggests that the consent of the left-behind parent is something which the removing parent may seek to establish by way of defence, is not its absence, rather, something which the left-behind parent must establish as part of his case under Art 3 that the removal was in breach of his rights of custody and thus, in effect, wrongful? But the conundrum is an old chestnut and I would not wish to say anything which might prompt resurrection of it, even if such were possible. In re P (A Child) (Abduction: Consent)[2005] Fam 293 this court decided that the specificity of the reference to consent in Art 13 sufficed to draw all issues of consent into it and out of Art 3; as it happens, I also consider that the decision was correct."
"the court is primarily concerned, not with the question of the other parent's perception of the applicant's conduct, but with the question whether the applicant acquiesced in fact." (2) The subjective intention of the wronged parent is a question of fact for the trial judge to determine in all the circumstances of the case, the burden of proof being on the abducting parent. (3) The trial judge, in reaching his decision on that question of fact, will no doubt be inclined to attach more weight to the contemporaneous words and actions of the wronged parent than to his bare assertions in evidence of his intention. But that is a question of the weight to be attached to evidence and is not a question of law. (4) There is only one exception. Where the words or actions of the wronged parent clearly and unequivocally show and have led the other parent to believe that the wronged parent is not asserting or going to assert his right to the summary return of the child and are inconsistent with such return, justice requires that the wronged parent be held to have acquiesced."
"…it is inconceivable that a court which reached the conclusion that there was a grave risk that the child's return would expose him to physical or psychological harm or otherwise place him in an intolerable situation would nevertheless return him to face that fate."
“if parents were deterred from seeking to make sensible arrangements, in consequence of what is usually an acknowledged breakdown in the relationship between them, for fear that the mere fact that they are able to contemplate that the child should remain where he has been taken will count against them in these proceedings. Such negotiations are, if anything, to be encouraged. They should not therefore necessarily fall within the exception or necessarily lead to the conclusion that as a matter of fact there was a subjective state of mind that was wholly content for the child to remain here.”
“Please comment on the psychiatric impact, if any, on the mother if the child is returned to the United States and she were to accompany the child? [The mother] does not wish to return to the United States where she feels there would be a lack of support for her and what is likely to be two children. However, she is not currently suffering from a mental health condition and given that she does not appear to have suffered from a definite mental health condition during her adult years, it is not impossible, but unlikely, that her mental state would deteriorate to such an extent that she would be diagnosed with a formal mental illness. She will, however, find this move to be very stressful. Specifically, please comment on what effect, if any, such a return might have on her parenting ability? I have expressed the view that whilst it is not impossible, it is unlikely that [the mother] would develop a formal mental illness on return to the United States. If this occurred, she would be able to access treatment to deal with her symptoms and it would be highly unlikely that she would deteriorate to such an extent that there would be a significant impact on her ability to care for one or two children.”
