"The States signatory to the present Convention, firmly convinced that the interests of children are of paramount importance in matters relating to their custody, desiring to protect children internationally from the harmful effects of their wrongful removal or retention and to establish procedures to ensure their prompt return to the State of their habitual residence, as well as to secure protection for rights of access, have resolved to conclude a Convention to this effect, and have agreed upon the following provisions."
"to secure the prompt return of children wrongfully removed to or retained in any Contracting State ...."
"The removal or the retention of a child is to be considered wrongful where" a) it is in breach of rights of custody attributed to a person, an institution or any other body, either jointly or alone, under the law of the State in which the child was habitually resident immediately before the removal or retention; and b) at the time of removal or retention those rights were actually exercised, either jointly or alone, or would have been so exercised but for the removal or retention .....” Article 4 provides inter alia: "
"Where a child has been wrongfully removed or retained in terms of Article 3and, 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. The judicial or administrative authority, even where the proceedings have been commenced after the expiration of the period of one year referred to in the preceding paragraph, shall also order the return of the child, unless it is demonstrated that the child is now settled in its new environment."
"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; orb) 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."
"In the light of all of this, the position should now be, in my view, that the gateway stage is confined to a straightforward and fairly robust examination of whether the simple terms of the Convention are satisfied in 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 his or herviews. Sub-tests and technicality of all sorts should be avoided. In particular, the Re T approach to the gateway stage should be abandoned."
"Once the discretion comes into play, the court may have to consider the nature and strength of the child's objections, the extent to which they are "authentically her own" or the product of the influence of the abducting parent, the extent to which they coincide or are at odds with other considerations which are relevant to her welfare, as well as the general Convention considerations referred to earlier. The older the child, the greater the weight that her objections are likely to carry. But that is far from saying that the child's objections should only prevail in the most exceptional circumstances."
" [60]. The law on the 'child's objection' defence underArt 13 of the Convention is comprehensively set out in the judgment of Black LJ in Re M (Republic of Ireland)(Child's Objections)(Joinder of Children as Parties to Appeal)[2015] 2 FLR 1074 (and endorsed by the Court of Appeal in Re F (Child's Objections)[2015] EWCA Civ 1022 ) and I have regard to the clear guidance given in that case. In summary, the position is as follows: i) The gateway stage should be confined to a straightforward and fairly robust examination of whether the simple terms of the Convention are satisfied in 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 his or her views ii) Whether a child objects is a question of fact. The child's views have to amount to an objection before Art 13 will be satisfied. An objection in this context is to be contrasted with a preference or wish iii) The objections of the child are not determinative of the outcome but rather give rise to a discretion. Once that discretion arises, the discretion is at large. The child's views are one factor to take into account at the discretion stage. iv) There is a relatively low threshold requirement in relation to the objections defence, the obligation on the court is to 'take account' of the child's views, nothing more v) At the discretion stage there is no exhaustive list of factors to be considered. The court should have regard to welfare considerations, in so far as it is possible to take a view about them on the limited evidence available. The court must give weight to Convention considerations and at all times bear in mind that the Convention only works if, in general, children who have been wrongfully retained or removed from their country of habitual residence are returned, and returned promptly. [61]. Once the discretion comes into play, the court may have to consider the nature and strength of the child's objections, the extent to which they are authentically the child's own or the product of the influence of the abducting parent, the extent to which they coincide or at odds with other considerations which are relevant to the child's welfare, as well as the general Convention considerations (Re M[2007] 1 AC 619 )."
