Delivers the following judgment, which was adopted on that date:
INTRODUCTION
1. The case concerns the enforcement of a seek and find order issued by the French authorities for the second applicant, the son of the first applicant, and his subsequent return to his mother, O. The applicants complained that proceedings brought against them by the Matosinhos Public Prosecutor’s Office had been unfair. They complained in particular about the lack of a hearing and the return of the second applicant to O. without an assessment of whether he was at grave risk of harm, in breach of their right to private and family life. They also claimed they had had no effective remedy in respect of those alleged wrongs. They relied on Articles 6 § 1, 8, and 13 of the Convention. THE FACTS
2. The applicants are father and son, who were born in 1970 and 2010 and are living in Serpins, Portugal and in France respectively. They were represented by Mr J.J. Ferreira Alves, a lawyer practising in Matosinhos. 3. The Government were represented by their Agent, Ms M.F. da Graça Carvalho, Deputy Attorney General and, after 1 September 2022, M. Ricardo Bragança de Matos, Public Prosecutor. 4. The first applicant lodged the application on his own behalf and on behalf of his son, the second applicant, who is a minor. 5. The facts of the case may be summarised as follows. Proceedings in France
6. On 28 October 2013, following the separation of the first applicant from the second applicant’s mother, O., the Family Court of Privas in France granted custody of the second applicant jointly to the first applicant and O. The child’s primary residence was with O. and the first applicant had contact rights, including staying contact at weekends and for half the school holidays. On 15 April 2015, following an appeal by the first applicant, this decision was upheld by the Court of Appeal of Nîmes, in France. 7. On 10 February 2014 and 7 May 2015, the first applicant unsuccessfully applied to the Privas Family Court for custody of the second applicant, saying he was not being properly educated and accusing O. of being violent and claiming that the child was at risk. 8. On 6 August 2015, the first applicant lodged an application with the Privas Family Court asking for the child’s primary residence to be transferred to him and for the mother to have contact “in a neutral place”. He claimed that the living conditions in O.’s home were poor and that she was not supporting the child’s school or ensuring that he had regular medical checkups. 9. On 7 December 2015, the Privas Family Court in France dismissed his application. 10. On 6 October 2017 the first applicant collected the child from school and noticed that he had an injury. The child was examined by a doctor, who found a ten centimetre abrasion on his right buttock which would have been caused by something coming into direct contact with the bare skin and which required the child to take ten days’ sick leave from school. On the following day the first applicant filed a complaint against O. for alleged violence against their son. He claimed that while the child was visiting him he had alleged that O. had beaten him using a plastic stick and that she had also done it several times before, using a blue belt or a shoe. He called two witnesses in this regard, who were heard. 11. On 8 October 2017 the first applicant failed to return the child to O. 12. On 9 October 2017 O. reported the child’s disappearance to the police authorities. After an investigation, the French police authorities found out that the first and second applicants were in Portugal. 13. On 13 October 2017 the first applicant again applied to the Privas Family Court for the child’s primary residence to be with him, saying he suspected the mother of being violent to the child. In reply, O. made a similar allegation against the first applicant. 14. On 14 November 2017 O. made a request to the French authorities for the return of the child under the Hague Convention on the Civil Aspects of International Child Abduction of 25 October 1980 (hereinafter “the Hague Convention” – see paragraph 32 below). This request was sent to the Central Authority designated for the purpose in Portugal, the Direcção-Geral de Reinserção e Serviços Prisionais (hereinafter “DGRSP”). It appears from the case file that the DGRSP did not communicate that request to any court. 15. On 27 November 2017 the Privas Family Court held an oral hearing of the first applicant’s application of 13 October 2017 (see paragraph 13 above). O., her lawyer and the first applicant’s representative were present. In the absence of the first applicant, his representative claimed that O. had been ill-treating the child for the last two years, saying the child had complained about it. In addition, the first applicant’s representative claimed to have seen signs of aggression on the second applicant’s body which had been confirmed by a doctor and two witnesses (see paragraph 10 above). O. denied these allegations, claiming that the first applicant had been making accusations against her ever since their separation and that on 8 October 2017, after spending the weekend with his father, the second applicant had not been returned to her (see paragraph 11 above). O. also asserted that the first applicant did not respect court orders or her rights as a mother. She referred to the child’s disappearance and asked to be granted exclusive custody of the child and for the first applicant’s contact rights to be suspended. 16. By a judgment of 11 December 2017 the Privas Family Court decided to grant exclusive custody to O. and to suspend the first applicant’s contact rights. It held that the first applicant had been fighting for primary residence rights from the outset and was apparently ready to do anything it took to achieve that. The Privas Family Court examined photographs provided by the first applicant. It found that the injuries that the child presented were genuine but that it had not been established that they had been caused by O., nor had it been established that she had beaten the child, as the first applicant had claimed. Furthermore, the child had not been heard alone by the court and the two witnesses (see paragraph 10 above) were not credible, since their statements had been produced on the same day the applicant had filed the criminal complaint against O. The Privas Family Court put considerable weight on the first applicant’s absence and the fact that he had breached previous judgments, taking the law into his own hands by disappearing with the child, against the interests of the mother and the child. 17. This judgment became final on 15 February 2018 as the first applicant had not filed any appeal. 18. In the meantime, on 30 January 2018, the Privas District Court had issued an European Arrest Warrant against the first applicant to have him tried for child abduction under Articles 227 §§ 7 and 9 of the French Criminal Code. 19. Subsequently, the French authorities made a seek and find request through the Schengen Information System for the second applicant as a missing person, asking for all necessary measures to be taken to protect the minor including, if need be, taking into the care of the authorities, and contacting the SIRENE (“supplementary information request at national entry”) National Office. Proceedings in Portugal
20. On 15 December 2017 the first applicant lodged an application for parental responsibility with the Family Court of Matosinhos, seeking sole custody of the second applicant and an order that the child’s official residence be with him. He stated that the child was living with him and attending school in Matosinhos. He also claimed that the boy’s mother, O., was aggressive and had beaten the child several times, providing evidence. He supplied the addresses of both their residence and the child’s school. 21. On 15 February 2018, at 9 a.m., the Portuguese police authorities took the second applicant out of school, executing the seek and find order issued by the French authorities (see paragraph 19 above). They kept him at the police station until 12.20 p.m., when they took him to the Public Prosecutor’s Office at the Matosinhos Family Court, which initiated an administrative process to assess whether a child protection case needed to be brought in the Family Court in accordance with Article 3 of Law no. 147/99 of 1 September 1999 (see paragraph 31 below). 22. Simultaneously, the first applicant was detained in execution of the European Arrest Warrant that had been issued against him by the French authorities for child abduction (see paragraph 18 above). He called a lawyer, who joined him at the police station, and issued a letter of authority whereby he authorised the advocate to represent him in the proceedings regarding the return of the second applicant. The first applicant was kept at the police station during that day and night. The parties did not specify how those proceedings developed. 23. At 3.40 p.m. the same day, O. appeared at the Public Prosecutor’s Office of the Matosinhos Family Court, in Portugal. At 5 p.m. the child was handed over to her following a decision of the Public Prosecutor in which she observed that:
- the DGRSP (see paragraph 14 above) had informed her that no action had been taken in respect of the second applicant following O.’s request under the Hague Convention;
- O. had been granted exclusive custody of the second applicant by a judgment of a French court (see paragraph 16 above);
- O. had appeared at the Public Prosecutor’s Office at the Matosinhos Family Court in Portugal;
- the judgment of the French court (see paragraphs 16 and 17 above) had suspended the first applicant’s contact rights with the child and that issue had been res judicata since that day (15 February 2018). 24. On 19 February 2018, the first applicant asked the Public Prosecutor’s Office in the Matosinhos Family Court to give him access to the administrative file (see paragraph 21 above). 25. On 20 February 2018 the Public Prosecutor closed the administrative process (see paragraph 21 above) on the grounds that there was no risk to the child given that he had been returned to his mother, who had sole custody and residence rights. It further ordered a copy of these proceedings to be sent to the Matosinhos Family Court. 26. On 22 February 2018, the first applicant’s request to have access to the administrative process (see paragraph 24 above) was granted. 27. By a decision of 8 March 2018, the Matosinhos Family Court rejected the first applicant’s application for parental responsibility (see paragraph 20 above). It noted that the Privas Family Court was the court with international jurisdiction on the matter given that the child was resident in France, and that it had itself no jurisdiction, in accordance with Article 17 of Council Regulation (EC) no. 2201/2003 of 27 November 2003 concerning jurisdiction and the recognition and enforcement of judgments in matrimonial matters and the matters of parental responsibility, repealing Regulation (EC) No. 1347/2000 (OJ 2003 L 338, p. 1) (known as “the Brussels II bis Regulation” – see paragraph 34 below), and it said that the unlawful removal of the child to Portugal by the first applicant had not altered that fact. 28. On 2 April 2018 the first applicant made a complaint to the Porto General Public Prosecutor’s Office about the Public Prosecutor of the Matosinhos Family Court (see paragraph 23 above). He also filed a disciplinary complaint against her with the High Council for Public Prosecution and a criminal complaint against the officers of the Public Prosecutor’s Office in the Matosinhos Family Court and the DGRSP (see paragraph 14 above). The applicant did not say, either in the application form or in his submissions, how those proceedings developed. RELEVANT LEGAL FRAMEWORK        DOMESTIC law   The Constitution

      INTERNATIONAL materials   The Hague Convention on the Civil Aspects of International Child Abduction of 25 October 1980

32. The relevant Articles of the Hague Convention (ratified by Portugal on 29 September 1983) are set out in X v. Latvia ([GC], no. 27853/09, § 34, ECHR 2013). Furthermore, regarding Central Authorities, the relevant provisions of the Hague Convention state the following:
Article 6
“A Contracting State shall designate a Central Authority to discharge the duties which are imposed by the Convention upon such authorities. Federal States, States with more than one system of law or States having autonomous territorial organisations shall be free to appoint more than one Central Authority and to specify the territorial extent of their powers. Where a State has appointed more than one Central Authority, it shall designate the Central Authority to which applications may be addressed for transmission to the appropriate Central Authority within that State.”
Article 7
“Central Authorities shall co-operate with each other and promote co-operation amongst the competent authorities in their respective States to secure the prompt return of children and to achieve the other objects of this Convention. In particular, either directly or through any intermediary, they shall take all appropriate measures –
a) to discover the whereabouts of a child who has been wrongfully removed or retained;
b) to prevent further harm to the child or prejudice to interested parties by taking or causing to be taken provisional measures;
c) to secure the voluntary return of the child or to bring about an amicable resolution of the issues;
d) to exchange, where desirable, information relating to the social background of the child;
e) to provide information of a general character as to the law of their State in connection with the application of the Convention;
f) to initiate or facilitate the institution of judicial or administrative proceedings with a view to obtaining the return of the child and, in a proper case, to make arrangements for organising or securing the effective exercise of rights of access;
g) where the circumstances so require, to provide or facilitate the provision of legal aid and advice, including the participation of legal counsel and advisers;
h) to provide such administrative arrangements as may be necessary and appropriate to secure the safe return of the child;
i) to keep each other informed with respect to the operation of this Convention and, as far as possible, to eliminate any obstacles to its application.”
Article 10
“The Central Authority of the State where the child is shall take or cause to be taken all appropriate measures in order to obtain the voluntary return of the child.”
Article 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 –
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. 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 considering the circumstances referred to in this Article, the judicial and administrative 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.”
   Council of Europe
33. The Guidelines of the Committee of Ministers of the Council of Europe on child-friendly justice were adopted by the Committee of Ministers on 17 November 2010. The relevant provisions read as follows:
B. Best interests of the child
“1. Member states should guarantee the effective implementation of the right of children to have their best interests be a primary consideration in all matters involving or affecting them. 2. In assessing the best interests of the involved or affected children:
a. their views and opinions should be given due weight;
b. all other rights of the child, such as the right to dignity, liberty and equal treatment should be respected at all times;
c. a comprehensive approach should be adopted by all relevant authorities so as to take due account of all interests at stake, including psychological and physical well-being and legal, social and economic interests of the child. 3. The best interests of all children involved in the same procedure or case should be separately assessed and balanced with a view to reconciling possible conflicting interests of the children. 4. While the judicial authorities have the ultimate competence and responsibility for making the final decisions, member states should make, where necessary, concerted efforts to establish multidisciplinary approaches with the objective of assessing the best interests of children in procedures involving them.”
C. Dignity
“1. Children should be treated with care, sensitivity, fairness and respect throughout any procedure or case, with special attention for their personal situation, well-being and specific needs, and with full respect for their physical and psychological integrity. This treatment should be given to them, in whichever way they have come into contact with judicial or non-judicial proceedings or other interventions, and regardless of their legal status and capacity in any procedure or case. 2. Children shall not be subjected to torture or inhuman or degrading treatment or punishment.”

When applying Articles 12 and 13 of the 1980 Hague Convention, it shall be ensured that the child is given the opportunity to be heard during the proceedings unless this appears inappropriate having regard to his or her age or degree of maturity. 3. A court to which an application for return of a child is made as mentioned in paragraph 1 shall act expeditiously in proceedings on the application, using the most expeditious procedures available in national law.

(f) if it is irreconcilable with a later judgment relating to parental responsibility given in another Member State or in the non-Member State of the habitual residence of the child provided that the later judgment fulfils the conditions necessary for its recognition in the Member State in which recognition is sought.
or
(g) if the procedure laid down in Article 56 has not been complied with.”
Article 28
Enforceable judgments

THE LAW        ALLEGED VIOLATION OF ARTICLE 8 OF THE CONVENTION

36. Relying on Article 6 § 1 of the Convention, and representing both himself and the second applicant, the first applicant complained that the proceedings brought by the Matosinhos Public Prosecutor’s Office at the request of the French authorities (see paragraphs 21-23 above) had been unfair. Under Article 8 of the Convention, he also complained that the second applicant had been returned to O. without an assessment of whether the child was at grave risk of harm and in a manner that breached their right to respect for their private and family life. Under Article 13 of the Convention he complained of the absence of an effective remedy in respect of these claims. 37. The Court, being the master of the characterisation to be given in law to the facts of the case (see Radomilja and Others v. Croatia [GC], nos. 37685/10 and 22768/12, §§ 114 and 126, 20 March 2018), will examine the complaints raised by the applicants solely from the standpoint of Article 8 of the Convention, which, in so far as relevant, reads as follows:
“1. Everyone has the right to respect for his private and family life ... 2. There shall be no interference by a public authority with the exercise of this right except such as is in accordance with the law and is necessary in a democratic society in the interests of national security, public safety or the economic well-being of the country, for the prevention of disorder or crime, for the protection of health or morals, or for the protection of the rights and freedoms of others.”
   Admissibility     The parties’ submissions

38. The Government, referring to the Court’s case-law, in particular Raw and Others v. France (no. 10131/11, § 51, 7 March 2013), and Strand Lobben and Others v. Norway ([GC], no. 37283/13, § 157, 10 September 2019), submitted that the first applicant did not have standing to represent the second applicant in the present case before the Court, since it is the parent entitled to custody who is the guardian of a child’s interests and the first applicant did not have custody of the second applicant. In addition, the Government said that although the Court might be concerned that a parent’s lack of standing could prevent certain of a child’s interests being brought to its attention, that concern would be unjustified in the context of proceedings to return a child following a case of international abduction by a father whose behaviour raised serious doubts about his capacity to pursue his child’s best interests. 39. The applicant opposed the Government’s objection, citing the same case-law as the Government (see paragraph 38 above). The Court’s assessment   The first applicant’s legal standing to act on behalf of the second applicant

40. The Court observes at the outset that a restrictive or purely technical approach should be avoided with regard to the representation of children before the Convention bodies (see Moretti and Benedetti v. Italy, no. 16318/07, § 32, 27 April 2010). 41. In this connection, the Court recalls that the key issue in relation to questions of standing is the risk that children’s interests might not be brought to the Court’s attention and that children could be denied effective protection of their Convention rights (see Strand Lobben and Others, cited above, § 157). Furthermore, the Court considers that aspects such as the ties between children and their representatives, which was central to the issue in the present case, the object of the complaint and the possibility of a conflict of interest must be taken into account (see Moretti and Benedetti, cited above, § 32). 42. The Court has previously used the criterion of the custodial parent in cases arising out of disputes between parents. In this type of cases, the Court has stated that it is in principle the parent entitled to custody who is the guardian of the child’s interests (see Hromadka and Hromadkova v. Russia, no. 22909/10, § 119, 11 December 2014, with further references, and Y.Y. and Y.Y. v. Russia, no. 43229/18, § 43, 8 March 2022). 43. However, the Court has accepted in the context of Article 8 of the Convention that minors can apply to the Court even, or indeed especially, if they are represented by a parent who is in conflict with the authorities and who has criticised the decisions and conduct of those authorities as not being consistent with the rights guaranteed by the Convention. In such cases, being a natural parent gives him or her the necessary standing to apply to the Court on the child’s behalf too, in order to protect the child’s interests (see Iosub Caras v. Romania, no. 7198/04, § 21, 27 July 2006, and Roengkasettakorn Eriksson v. Sweden, no. 21574/16, § 61, 19 May 2022, with further references). 44. Even where parents have not had parental rights, the Court has applied the key criterion of ensuring that children’s Convention interests can be brought before the Court (see the case-law cited in paragraph 41 above) and has previously accepted that they can apply to it on behalf of their minor children (see Scozzari et Giunta c. Italie [GC], nos. 39221/98 and 41963/98, § 138, 13 July 2000; Raw and Others v. France, no. 10131/11, § 51, 7 March 2013; and Strand Lobben, cited above, § 157). 45. Turning to the present case, the Court observes that by the time the application was lodged (16 April 2018), O. had been granted exclusive custody of the child, while the applicant had had his contact rights suspended (see paragraph 16 above). However, in view of the complaints brought before the Court, particularly concerning the return of the child to O., it appears that there is a conflict of interest regarding the child. Relying on the criterion of custody could jeopardise the child’s interests by not allowing this complaint to be brought to the Court’s attention (see the case-law cited in paragraph 41 above). 46. Given the object and nature of the complaints brought by the first applicant on behalf of his son, the second applicant (see paragraph 36 above), the Court further observes that the first applicant is in conflict with the authorities regarding the return of the child to O. and that he criticises their decisions and conduct as not being consistent with the rights guaranteed by the Convention. 47. Furthermore, the Court observes that the first applicant’s parental responsibility for the second applicant was never withdrawn (see, a fortiori, Scozzari et Giunta, cited above, § 138, where the Court accepted that a natural mother who had been deprived of parental rights had the necessary power to apply to the Court on the children’s behalf in order to protect their interests). 48. Consequently, having in mind the circumstances of the case and the object of the complaints, the Court sees no reason to depart from the understanding that, given that the first applicant had parental responsibility for the second applicant, he had standing to act on behalf of him. Accordingly, the Government’s objection must be dismissed. 49. The Court further notes that it is accepted that the tie between the applicant and his son, the second applicant, comes within the scope of family life within the meaning of Article 8 of the Convention. That Article is therefore applicable to the situation of which the applicant complained (see Maire v. Portugal, no. 48206/99, § 68, ECHR 2003 VII). Conclusion as to the admissibility
50. The Court notes that the applicants’ complaints under Article 8 are neither manifestly ill-founded nor inadmissible on any other grounds listed in Article 35 of the Convention. They must therefore be declared admissible. Merits     The parties’ submissions   The applicant

51. The first applicant complained about the return of his son to O. in proceedings conducted by the Public Prosecutor which in his view lacked fairness (see paragraphs 21-23 above). In particular he contested the manner in which the return was dealt with by the Portuguese authorities. He submitted that he had not been heard prior to the return of his son to O. and that, while that return was being carried out, he had been detained and then remanded in custody at a police station under a European Arrest Warrant issued on 30 January 2018 (see paragraphs 18 and 22 above). Furthermore, he argued that the return of the child to his mother was not ordered by a Judge. Lastly, he argued that there was a risk to the child in case of return to his mother and that the Portuguese authorities did not assess it. 52. The first applicant also complained about the fact that the child had been located by the police and kept in the police station until he was transferred to the Public Prosecutor’s Office (see paragraph 21 above). (b) The Government
53. The Government submitted that the Portuguese Central Authority designated for the purposes of Article 6 of the Hague Convention did not take any steps under Article 10 of that treaty (see paragraph 32 above) because it was unaware of the child’s whereabouts. They explained that, instead, the seek and find request (see paragraph 19 above) was entered into the SIS II under Article 32 of Council Decision 2007/533/JHA of 12 June 2007 (see paragraph 35 above). They gave this as the explanation why, when the child was located, he was taken to the Public Prosecutor’s Office of the Matosinhos Family Court to assess whether there were grounds for initiating child protection proceedings (see paragraph 21 above). The Government observed that the Privas Court’s judgment in conjunction with the fact that the mother was already in Portugal meant that the Public Prosecutor had no standing to initiate child protection proceedings given that the mother had an exclusive custody order (see paragraphs 16 and 23 above). Referring to Nuutinen v. Finland (no. 32842/96, § 129, ECHR 2000-VIII) and M.R. and L.R. v. Estonia ((dec.), no. 13420/12, § 43, 15 May 2012), the Government contended that in cases of child abduction, there is a presumption in favour of the prompt return of the child to the “left behind” parent and therefore the Portuguese authorities were unable to act as the first applicant wished. 54. The Government asserted that the enforcement of the French judgment and the return of the child were fair and that the interests protected by Article 8 of the Convention had been respected. In particular, they contended that the Public Prosecutor’s Office of the Matosinhos Family Court had acted swiftly to hand over the child to his mother on the very same day, in order to minimise the potentially traumatic effects of police intervention or of placing the child in foster care. In their view, the child was therefore never at risk within the meaning of Law no. 147/99 of September 1999 (see paragraph 31 above). They further observed that none of the applicants had been heard because no judicial proceedings had been initiated and because, as far as the first applicant was concerned, he lacked standing to act on behalf of his son. 55. The Government also claimed that parental responsibility proceedings had been dealt with by the Privas Family Court, which was the appropriate court, and that there was no indication that the first applicant had felt his rights had not been protected in those proceedings. Furthermore, they argued that the return of the child had been based on the provisions of the Brussels II bis Regulation (see paragraph 34 above). Consequently, there was no serious or substantiated complaint to the effect that a Convention right had been breached. The presumption first established in Bosphorus Hava Yolları Turizm ve Ticaret Anonim Şirketi v. Ireland ([GC], no. 45036/98, ECHR 2005‑VI) and confirmed in, inter alia, Avotiņš v. Latvia ([GC], no. 17502/07, § 105, 23 May 2016), under which States parties would not be liable under the Convention for breaches which arise as a consequence of the necessity of complying with other international legal obligations had not been rebutted. They asserted that the interference with the first applicant’s right to family life was in accordance with the law and necessary in a democratic society for the protection of the rights of the second applicant and to prevent disorder and crime. The Court’s assessment   General principles

56. The relevant principles regarding the interference with the right to respect for family life, as well as the State’s positive obligations under Article 8 of the Convention in cases concerning international child abduction have been summarised in X. v. Latvia ([GC], no. 27853/09, §§ 92-108, ECHR 2013), and Neulinger and Shuruk v. Switzerland ([GC], no. 41615/07, §§ 131‑40, ECHR 2010). 57. The Court reiterates that the Convention must be applied in accordance with the principles of international law (see Maire, cited above, § 72, and Maumousseau and Washington v. France, no. 39388/05, § 60, 6 December 2007, and the cases cited therein). As regards the obligations that Article 8 of the Convention imposes on the Contracting States with respect to reuniting parents with their children, they should be interpreted in the light of the requirements of the Hague Convention (see paragraph 32 above; see Ignaccolo-Zenide v. Romania, no. 31679/96, § 95, 25 January 2000; Iglesias Gil and A.U.I. v. Spain, no. 56673/00, § 51, 29 April 2003; and Maumousseau and Washington, cited above, § 60). 58. Furthermore, there is a broad consensus in support of the idea that in all decisions concerning children, their best interests must be paramount. The same philosophy is inherent in the Hague Convention (see Vladimir Ushakov v. Russia, no. 15122/17, § 79, 18 June 2019). 59. In relations between EU member States the rules on child abduction contained in the Brussels II bis Regulation (see paragraph 34 above) supplement those already laid down in the Hague Convention (see paragraph 32 above). Both instruments associate the best interests of the child with restoration of the status quo by means of a decision ordering the child’s immediate return to his or her country of habitual residence in the event of unlawful abduction, while taking account of the fact that non-return may sometimes prove justified for objective reasons that correspond to the child’s best interests. This explains the existence of exceptions, specifically in the event of a grave risk that the child’s return would expose him or her to physical or psychological harm or otherwise place him or her in an intolerable situation within the meaning of Article 13 (b) of the Hague Convention (see Sévère v. Austria, no. 53661/15, § 100, 21 September 2017, and the cases cited therein). 60. The Court reiterates that it does not propose to substitute its own assessment for that of the domestic courts. That said, notwithstanding the State’s margin of appreciation, the Court must satisfy itself that the decision-making process leading to the taking of the disputed decisions by the domestic authorities was fair and allowed those concerned to present their case fully, and that the best interests of the child were defended (see X v. Latvia, cited above, § 102, and the references therein). 61. In particular, the Court reiterates that Article 8 of the Convention imposes on the domestic authorities a particular procedural obligation in this respect: when assessing an application for a child’s return, the courts must not only consider arguable allegations of a “grave risk” for the child in the event of return, but must also make a ruling giving specific reasons in the light of the circumstances of the case. This will enable the Court, whose task is not to take the place of the national courts, to carry out the European supervision entrusted to it (see X v. Latvia, cited above, § 107, and Michnea v. Romania, no. 10395/19, § 39, 7 July 2020). The application of those principles to the facts of the present case
62.
