“The judicial or administrative authorities of the Contracting State of the habitual residence of the child have jurisdiction to take measures directed to the protection of the child's person or property.”
“In all cases of urgency, the authorities of any Contracting State in whose territory the child or property belonging to the child is present have jurisdiction to take any necessary measures of protection.”
“Subject to Article 7, the authorities of a Contracting State in whose territory the child or property belonging to the child is present have jurisdiction to take measures of a provisional character for the protection of the person or property of the child which have a territorial effect limited to the State in question, in so far as such measures are not incompatible with measures already taken by authorities which have jurisdiction under Articles 5 to 10.”
“(1) The authorities of a Contracting State which have jurisdiction under Articles 5 to 10 to take measures for the protection of the person or property of the child must abstain from exercising this jurisdiction if, at the time of the commencement of the proceedings, corresponding measures have been requested from the authorities of another Contracting State having jurisdiction under Articles 5 to 10 at the time of the request and are still under consideration. (2) The provisions of the preceding paragraph shall not apply if the authorities before whom the request for measures was initially introduced have declined jurisdiction.”
“In so far as the submissions to us suggested that the inherent jurisdiction of the English courts was unaffected by these instruments, and remained there in the background awaiting the call, it is not a suggestion I can accept. Where one or the other instrument applies, recourse can only be had to the inherent jurisdiction if that is permitted by the jurisdictional code that that instrument establishes. The decision of the Supreme Court in A v A and another (Children: Habitual Residence)[2013] UKSC 60 ,[2014] AC 1 demonstrates this in relation to Brussels IIa and I see no reason why matters should be different in relation to the 1996 Hague Convention.”
“The instinctive reaction of the English lawyer in these circumstances is to reach for the inherent jurisdiction. However, in my view, it cannot assist here. In so far as it concerns jurisdiction, the whole purpose of the 1996 Hague Convention, as with Brussels IIa, is to determine, as between Contracting States, the State whose authorities have jurisdiction to take measures directed to the protection of the person or property of the child (see Article 1(1) a)). That would be defeated if, notwithstanding an absence of jurisdiction under the Convention, a Contracting State were to be able to assume jurisdiction by virtue of a domestic rule.”
“I am, uniquely in my own experience, allowing the inherent jurisdiction of the High Court to trump the statutory framework in truly exceptional circumstances. These circumstances are, firstly, I don’t think it would be appropriate for a judge of the Family Division to make an order to allow a father, [where] there is a question mark if he is an abductor, to collect the children and take them to Kyiv or perhaps anywhere else. It does not seem something safe for me to order. In my judgment, it would be wrong for me to make an order to require the children to go back to Kyiv, with so much tragedy and so much uncertainty in the news about this.”
“The court having made no determination on jurisdiction or habitual residence, the Ukrainian authorities are invited to give all possible assistance of securing the return of the children to the jurisdiction of England and Wales.”
“The term “corresponding measures” is not defined in the Convention but it appears that, for Article 13 to apply, the requests before both Contracting States must be the same or similar in substance.”
