“…the Court acknowledges that the Romanian court vested with a request for the return of an underage, on the grounds of the Convention of the Hague of 1980, is summoned to assess the compliance with the following conditions: the habitual residence of the underage is in the state that requests her return; the displacement or the retaining of the underage on the territory of another state occurred by violating an entrustment right, assigned to the applicant by the Law of the state in which the child used to have her habitual residence; at the time of the child displacement or non-return, this right was effectively exercised; the amount of time that passed between the child’s displacement or non-return and the date of the return application; the exceptions from the return rule recognized by the Convention.”
“Article 12 Where a child has been wrongfully removed or retained in terms of Article 3 and, at the date of the commencement of the proceedings before the judicial or administrative authority of the Contracting State where the child is, a period of less than one year has elapsed from the date of the wrongful removal or retention, the authority concerned shall order the return of the child forthwith. The judicial or administrative authority, even where the proceedings have been commenced after the expiration of the period of one year referred to in the preceding paragraph, shall also order the return of the child, unless it is demonstrated that the child is now settled in its new environment. Where the judicial or administrative authority in the requested State has reason to believe that the child has been taken to another State, it may stay the proceedings or dismiss the application for the return of the child.”
“[31] It seems to me that a wrongful act of retention, whether anticipatory/repudiatory (i.e. happening before the due date for return), or actual (i.e. happening after the due date of return), requires there to be, as a matter of fact, a clearly agreed due date of return. I believe that every reported case about retention has involved a finite period away with a due date of return. In my opinion it is implicit in the concept of wrongful retention, as referred to in Articles 1, 3, 12, 13, 14, 15 and 16, that the wrongful act must take place within, or immediately following, an agreed finite period of care by the retaining parent”

“The full proposition is that, once an issue of a matrimonial offence has been litigated between the parties and decided by a competent court, neither party can claim as of right to reopen the issue and litigate it all over again if the other party objects (that is what is meant by saying that estoppels bind the parties): but the divorce court has the right, and indeed the duty in a proper case, to reopen the issue, or to allow either party to reopen it, despite the objection of the other party (that is what is meant by saying that estoppels do not bind the court). Whether the divorce court should reopen the issue depends on the circumstances. If the court is satisfied that there has already been a full and proper inquiry in the previous litigation, it will often hold that it is not necessary to hold another inquiry all over again: but if the court is not so satisfied, it has a right and a duty to inquire into it afresh. If the court does decide to reopen the matter, then there is no longer any estoppel on either party. Each can go into the matter afresh.”
