"(a) it is in breach of rights of custody attributed to a person… either jointly or alone, under the law of the State in which the child was habitually resident immediately before the removal…; and(b) at the time of removal… those rights were actually exercised, either jointly or alone, or would have been so exercised but for the removal… ."
"The whole object of the Convention is to secure the swift return of children wrongfully removed from their home country, not only so that they can return to the place which is properly their 'home', but also so that any dispute about where they should live in the future can be decided in the courts of their home country, according to the laws of their home country and in accordance with the evidence which will mostly be there rather than in the country to which they have been removed."
"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…" (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. The judicial … authority may also refuse to order the return of the child if it finds that the child objects to being returned and has attained an age and degree of maturity at which it is appropriate to take account of its views.In considering the circumstances referred to in this Article, the judicial … authorities shall take into account the information relating to the social background of the child provided by the Central Authority or other competent authority of the child's habitual residence."
"(1) Consent to the removal of the child must be clear and unequivocal. (2) Consent can be given to the removal at some future but unspecified time or upon the happening of some future event. (3) Such advance consent must, however, still be operative and in force at the time of the actual removal. (4) The happening of the future event must be reasonably capable of ascertainment. The condition must not have been expressed in terms which are too vague or uncertain for both parties to know whether the condition will be fulfilled. Fulfilment of the condition must not depend on the subjective determination of one party, for example, 'Whatever you may think, I have concluded that the marriage has broken down and so I am free to leave with the child.' The event must be objectively verifiable. (5) Consent, or the lack of it, must be viewed in the context of the realities of family life, or more precisely, in the context of the realities of the disintegration of family life. It is not to be viewed in the context of nor governed by the law of contract. (6) Consequently consent can be withdrawn at any time before actual removal. If it is, the proper course is for any dispute about removal to be resolved by the courts of the country of habitual residence before the child is removed. (7) The burden of proving the consent rests on him or her who asserts it. (8) The enquiry is inevitably fact specific and the facts and circumstances will vary infinitely from case to case. (9) The ultimate question is a simple one even if a multitude of facts bear upon the answer. It is simply this: had the other parent clearly and unequivocally consented to the removal?"
"31. … By its very terms, [Article 13] is of restricted application. The words of article 13 are quite plain and need no further elaboration or "gloss".32. First, it is clear that the burden of proof lies with the "person, institution or other body" which opposes the child's return. It is for them to produce evidence to substantiate one of the exceptions. There is nothing to indicate that the standard of proof is other than the ordinary balance of probabilities. But in evaluating the evidence, the court will of course be mindful of the limitations involved in the summary nature of The Hague Convention process. It will rarely be appropriate to hear oral evidence of the allegations made under article 13(b) and so neither those allegations nor their rebuttal are usually tested in cross-examination.33. Second, the risk to the child must be "grave"
‘Intolerable' is a strong word, but when applied to a child must mean ‘a situation which this particular child in these particular circumstances should not be expected to tolerate'. It is, as Art 13(b) makes clear, the return to the requesting state, rather than the enforced removal from the requested state, which must have this effect. Thus the English courts have sought to avoid placing the child in an intolerable situation by extracting undertakings from the applicant as to the conditions in which the child will live when he returns and by relying on the courts of the requesting state to protect him once he is there. In many cases this will be sufficient. But once again, the fact that this will usually be sufficient to avoid the risk does not mean that it will invariably be so. In Hague Convention cases within the European Union, Art 11.4 of the Council Regulation (EC) No 2201/2003 of27 November 2003 concerning jurisdiction and the recognition and enforcement of judgments in matrimonial matters and in matters of parental responsibility, repealing Regulation (EC) No 1347/2000 (Brussels II Revised) (2003) OJ L 338/1 expressly provides that a court cannot refuse to return a child on the basis of Art 13(b) ‘if it is established that adequate arrangements have been made to secure the protection of the child after his or her return'. Thus it has to be shown that those arrangements will be effective to secure the protection of the child. With the best will in the world, this will not always be the case. No-one intended that an instrument designed to secure the protection of children from the harmful effects of international child abduction should itself be turned into an instrument of harm.’
“When one of the girl’s parents emigrates abroad as a result of marriage and the like, the other party shall cooperate totally to arrange all necessary matters including the visits to the satisfaction of the two parents and if they emigrate for personal reasons, they cannot force the other side to agree to cooperate and in addition they can even detain them.”
