“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.”
“13. 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: … (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 or administrative 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.”
“i. There is no need for Art 13(b) to be narrowly construed. By its very terms it is of restricted application. The words of Art 13 are quite plain and need no further elaboration or gloss. ii. The burden lies on the person (or institution or other body) opposing return. It is for them to produce evidence to substantiate one of the exceptions. The standard of proof is the ordinary balance of probabilities but in evaluating the evidence the court will be mindful of the limitations involved in the summary nature of the Convention process. iii. The risk to the child must be ‘grave’. It is not enough for the risk to be ‘real’. It must have reached such a level of seriousness that it can be characterised as ‘grave’. Although ‘grave’ characterises the risk rather than the harm, there is in ordinary language a link between the two. iv. The words ‘physical or psychological harm’ are not qualified but do gain colour from the alternative ‘or otherwise’ placed ‘in an intolerable situation’. ‘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’. v. Art 13(b) looks to the future: the situation as it would be if the child were returned forthwith to his or her home country. The situation which the child will face on return depends crucially on the protective measures which can be put in place to ensure that the child will not be called upon to face an intolerable situation when he or she gets home. Where the risk is serious enough the court will be concerned not only with the child’s immediate future because the need for protection may persist. vi. Where the defence under Art 13(b) is said to be based on the anxieties of a respondent mother about a return with the child which are not based upon objective risk to her but are nevertheless of such intensity as to be likely, in the event of a return, to destabilise her parenting of the child to a point where the child’s situation would become intolerable the court will look very critically at such an assertion and will, among other things, ask if it can be dispelled. However, in principle, such anxieties can found the defence under Art 13(b). [32] The Supreme Court made clear that the approach to be adopted in respect of the harm defence is not one that demands the court engage in a fact-finding exercise to determine the veracity of the matters alleged as ground the defence under Art 13(b). Rather, the court should assume the risk of harm at its highest on the evidence available to the court and then, if that risk meets the test in Art 13(b), go on to consider whether protective measures sufficient to mitigate harm are identified. It follows that if, having considered the risk of harm at its highest on the available evidence, the court considers that it does not meet the imperatives of Art 13(b), the court is not obliged to go on to consider the question of protective measures.”
“"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 article 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.”
“35. In her definition of an objection, (counsel) had, in my view, introduced an unwarranted gloss on the simple words of Article 13. It is not necessary to establish that the child has “a wholesale objection” to returning to the country of habitual residence and “cannot think of anything positive to say about that other country”
“… in cases where a discretion arises from the terms of the Convention itself, it seems to me that the discretion is at large. The court is entitled to take into account the various aspects of the Convention policy, alongside the circumstances which gave the court a discretion in the first place and the wider considerations of the child’s rights and welfare.”
