“if the court does not follow the approach referred to above, it would create the inevitable prospect of the court's evaluation falling between two stools. The court's "process of reasoning", to adopt the expression used by Lord Wilson in Re S, at [22], would not include either (a) considering the risks to the child or children if the allegations were true; nor (b) confidently discounting the possibility that the allegations gave rise to an Article 13(b) risk. The court would, rather, by adopting something of a middle course, be likely to be distracted from considering the second element of the Re E approach, namely "how the child can be protected against the risk" which the allegations, if true, would potentially establish.”
