“The concept of habitual residence under Article 8(1) of the Regulations must be interpreted as meaning that it corresponds to the place which reflects some degree of integration by the child in a social and family environment. To that end, in particular the duration, regularity, the conditions and reasons for the stay on the territory of the Member State and the family’s move to that state, the child’s nationality, the place and conditions of attendance at school, linguistic knowledge and the family and social relationships of the child in that State must be taken into consideration. It is for the national court to establish the habitual residence of the child, taking account of all the circumstances specific to each individual case.”
“The concept of habitual residence… must be interpreted as meaning that such residence corresponds to the place which reflects some degree of integration by the child in a social and family environment. To that end, where the situation concerned is that of an infant who has been staying with her mother only a few days in a Member State -- other than that of her habitual residence -- to which she has been removed, the factors which must be taken into consideration include, first, the duration, regularity, conditions and reasons for the stay in the territory of that Member State and for the mother’s move to that State, and, second, with particular reference to the child’s age, the mother’s geographic and family origins and the family and social connections which the mother and child have with that Member State. It is for the national court to establish the habitual residence of the child taking account of all the circumstances of facts specific to each individual case.”
“In the explanatory memorandum to the request [of2 June 2016 ] the applicant stated that the participant [father] (permanently residing in England) was violent towards her, in the presence of children, hence the applicant, in order to secure peace and safety for the children, has decided to return to Poland (up to now the parties have resided in England).”
“The effect of an appeal from a decision by the court first seised that it has no jurisdiction does not appear to be settled by authority: c.f. Dicey, Morris & Collins, Conflict of Laws, 14th ed. 2006, paras 12-047, 12-062; Briggs and Rees, Civil Jurisdiction and Judgments, 4th ed 2005, para 2.205. It is true that a judgment for the purposes of Brussels I is final even if an appeal is pending: e.g. Articles 37 and 46. But the object of Article 27 is to prevent irreconcilable judgments, and as a matter of policy it would be very odd if proceedings in the court second seised could continue even if on appeal the jurisdiction of the court first seised is established. Consequently, we consider (contrary to the view of the judge) that Article 27 applies until the proceedings in the court first seised are finally determined in relation to its jurisdiction. That would mean that the expression in Article 27.1 "until such time as the jurisdiction of the court first seised is established" should be interpreted to include the case where the court first seised has declared that it has no jurisdiction, but an appeal is pending against that decision …”
"1. A court shall be deemed to be seised: (a) at the time when the document instituting the proceedings or an equivalent document is lodged with the court, provided that the applicant has not subsequently failed to take the steps he was required to take to have service effected on the respondent; …"
"As I see it, as stated above, the way article 16 works is that there is seisin on the date identified subject to a condition defeasant. That is not a case of apparent seisin maturing into actual seisin but there being actual seisin, which would take priority over any subsequent seisin, unless there was no service or lodgement."
“When taking the children from Great Britain to Poland, [the mother] was executing her custody rights by taking the minors to their place of permanent residence. No breach of [the father’s] custody rights occurred, since his personal habit of travelling between both countries had already been established, and he has agreed that the family should reside in Poland in June 2016.”
“at least since 2014, the children witnessed the use of violence against [the mother] by the father”
