The decision of the US Supreme Court in Monasky v. Taglieri confirms that the determination of the newborn/infant's habitual residence should focus on the intention and habitual residence of his/her parents or caregiver – the analytical approach is parent-centered. The US Supreme Court ruling, in affirming the decision of the Sixth Circuit Court of Appeals, also clarifies that the determination of the habitual residence of the adolescent/older child should focus on his/her own acclimatization – the analytical approach is child-centered. According to the Supreme Court, the determination of the habitual residence of the child found to be within a transnational family conflict, such as that contemplating an international abduction or an international marital dispute concerning, inter alia, parental authority, must take into account the specific circumstances and facts of each individual case – fact-intensive determination. Based on the practice of other States and of the CJEU, this judgment considers that a predetermined formula applied to the analysis of the child's habitual residence cannot be deemed to be in conformity with the objectives of the 1980 Hague Convention (applicable to the United States and Italy, both of which are involved in this case) – in particular, by virtue of the fact-based approach followed by this notion, unlike other connecting factors such as domicile and nationality. Regrettably, in affirming the decision the Supreme Court upheld the reasoning of the Court of Appeal as a whole. Thus, it set aside two elements which were not considered in depth by the Court and which in the author's opinion it should have retained, regardless of the child's age and given the child's development within a potentially disruptive family context: The principle of the best interests of the child and the degree of instability attributed to the child's physical presence before the wrongful removal.
