“…we did a dealin September” about dividing the child’s time as to 6 months in the care of each of them. She accepted that whilst she had suggested something along these lines (i.e. the child was to spend all the school holidays with the father amounting to a significant part of the year later described as the ‘Italian’ shared parenting model) there had been no such “deal”
“48. In my judgment the following principles should be deduced from these authorities. (1) Consent to the removal of the child must be clear and unequivocal. (2) Consent can be given to the removal at some future but unspecified time or upon the happening of some future event. (3) Such advance consent must, however, still be operative and in force at the time of the actual removal. (4) The happening of the future event must be reasonably capable of ascertainment. The condition must not have been expressed in terms which are too vague or uncertain for both parties to know whether the condition will be fulfilled. Fulfilment of the condition must not depend on the subjective determination of one party, for example, “Whatever you may think, I have concluded that the marriage has broken down and so I am free to leave with the child.”
"In my judgment, therefore, in the ordinary case the court has to determine whether in all the circumstances of the case the wronged parent has, in fact, gone along with the wrongful abduction. Acquiescence is a question of the actual subjective intention of the wronged parent, not of the outside world's perception of his intentions." 41. Lord Browne-Wilkinson then went on to describe "the exception"
"It is a feature of all developed systems of law that there are circumstances in which one party, A, has so conducted himself as to mislead the other party, B, as to the true state of the facts. In such a case A is not allowed subsequently to assert the true facts as against B. In English law, this is typically represented by the law of estoppel but I am not suggesting that the rules of English law as to estoppel should be imported into the Convention. What is important is the general principle to be found in all developed systems of law. It follows that there may be cases in which the wronged parent has so conducted himself as to lead the abducting parent to believe that the wronged parent is not going to insist on the summary return of the child. Thus the wronged parent may sign a formal agreement that the child is to remain in the country to which he has been abducted. Again, he may take an active part in proceedings in the country to which the child has been abducted to determine the long-term future of the child. No developed system of justice would permit the wronged parent in such circumstances to go back on the stance which he has, to the knowledge of the other parent, unequivocally adopted: to do so would be unjust. Therefore in my judgment there are cases (of which In re A.Z. (a Minor) (Abduction: Acquiescence)[1993] 1 FLR 682 is one) in which the wronged parent, knowing of his rights, has so conducted himself vis-à-vis the other parent and the children that he cannot be heard to go back on what he has done and seek to persuade the judge that, all along, he has secretly intended to claim the summary return of the children. However, in my judgment these will be strictly exceptional cases. In the ordinary case behaviour of that kind will be likely to lead the judge to a finding that the actual intention of the wronged parent was indeed to acquiesce in the wrongful removal. It is only in cases where the judge is satisfied that the wronged parent did not, in fact, acquiesce but his outward behaviour demonstrated the contrary that this exceptional case arises. My Lords, in my judgment these exceptional circumstances can only arise where the words or actions of the wronged party show clearly and unequivocally that the wronged parent is not insisting on the summary return of the child: they must be wholly inconsistent with a request for the summary return of the child. Such clear and unequivocal conduct is not normally to be found in passing remarks or letters written by a parent who has recently suffered the trauma of the removal of his children. Still less is it to be found in a request for access showing the wronged parent's desire to preserve contact with the child, in negotiations for the voluntary return of the child, or in the parent pursuing the dictates of his religious beliefs."
"(4) There is only one exception. Where the words or actions of the wronged parent clearly and unequivocally show and have led the other parent to believe that the wronged parent is not asserting or going to assert his right to the summary return of the child and are inconsistent with such return, justice requires that the wronged parent be held to have acquiesced."
“I deal with two live issues. First consent. The parties agree that the onus is on the mother to establish this, that it should be shown in a manner similar to that which is required now for acquiescence in light of the House of Lords decision in Re H (Abduction: Acquiescence)[1998] AC 72 …… The task of the court is to find as a fact whether the father subjectively intended to and did give unconditional consent to the removal of the child.”
“When I consider the issue of “consent”
"that people lie for all sorts of reasons, including shame, humiliation, misplaced loyalty, panic, fear, distress, confusion and emotional pressure and the fact that somebody lies about one thing does not mean it actually did or did not happen and / or that they have lied about everything"
"[18]…Whilst the impression a witness makes upon the Judge will always be important and signals the inestimable advantage the first instance Judge has, in assessing the evidence, it is not a substitute for a detailed analysis of those features of the evidence which reinforce the reliability of the allegation."
"[36] Generally speaking, it is no longer considered that inability to assess the demeanour of witnesses puts appellate judges "in a permanent position of disadvantage as against the trial judge"
“[15] … Where oral evidence has been given by the key players it will often, if not always, be important to give a short appraisal of the witness' credibility and, where the testimony of one is preferred over another, a short statement of the reasons why that is so. … [16] In summary, the well established approach of an appellate court in cases such as this is that a basic, short but clear description of the factors considered and the reasoning that underpins any conclusion is all that is required. But it is nevertheless required…”
