The second subparagraph of Article 47(2) of the
Brussels II Regulation (No 2201/2003) must be interpreted as meaning
that a judgment delivered subsequently by a court in the Member State
of enforcement which awards provisional rights of custody and is deemed
to be enforceable under the law of that State cannot preclude enforcement
of a certified judgment delivered previously by the court which has
jurisdiction in the Member State of origin and ordering the return
of the child.
Enforcement of a certified judgment cannot
be refused in the Member State of enforcement because, as a result
of a subsequent change of circumstances, it might be seriously detrimental
to the best interests of the child. Such a change must be pleaded
before the court which has jurisdiction in the Member State of origin,
which should also hear any application to suspend enforcement of its
judgment.
