“It is my view that, if it is the case that [the father] instructed his parents to murder [the mother] and is directly involved in intra-familial homicide, then this would be indicative of domestic abuse at its highest. In such circumstances I would be extremely concerned about S returning to his father’s care in the USA and the only safe scenario I could envisage would be for S to be cared for outside of the home in foster care or a similar arrangement pending a full welfare determination by the US authorities.”
“[92] This does not mean, as I said in In re C, at para 39, that it was being "suggested that no evaluative assessment of the allegations could or should be undertaken by the court". In support of this conclusion, I quoted what Black LJ (as she then was) had said in In re K (A Child) (Abduction: Child's Objections)[2015] EWCA Civ 720 at [53], about the In re E approach: “I do not accept that a judge is bound to take this approach if the evidence before the court enables him or her confidently to discount the possibility that the allegations give rise to an article 13b risk.”
"Where there are disputed allegations which can neither be tried nor objectively verified, the focus of the inquiry is bound to be on the sufficiency of any protective measures which can be put in place to reduce the risk. The clearer the need for protection, the more effective the measures will have to be." [94] In the Guide to Good Practice, at para 40, it is suggested that the court should first "consider whether the assertions are of such a nature and of sufficient detail and substance, that they could constitute a grave risk" before then determining, if they could, whether the grave risk exception is established by reference to all circumstances of the case. In analysing whether the allegations are of sufficient detail and substance, the judge will have to consider whether, to adopt what Black LJ said in In re K, “the evidence before the court enables him or her confidently to discount the possibility that the allegations give rise to an article 13(b) risk”. In making this determination, and to explain what I meant in In re C, I would endorse what MacDonald J said in Uhd v McKay[2019] EWHC 1239 (Fam) ,[2019] 2 FLR 1159 , para 7, namely that "the assumptions made by the court with respect to the maximum level of risk must be reasoned and reasonable assumptions" (my emphasis). If they are not "reasoned and reasonable", I would suggest that the court can confidently discount the possibility that they give rise to an article 13(b) risk.” "
