“Criticism of Expert witnesses 101. It is, unfortunately, sometimes the case that a judge in civil or family proceedings may be driven to criticise the professional practice or expertise of an expert witness in the case. Although what I have said with regard to a right to fair process under ECHR, Art 8 or the common law may in principle apply to such an expert witness, it will, I would suggest, be very rare that such a witness’ fair trial rights will be in danger of breach to the extent that he or she would be entitled to some form of additional process, such a legal advice or representation during the hearing. That this is so is, I suspect, obvious. The expert witness should normally have had full disclosure of all relevant documents. Their evidence will only have been commissioned, in a family case, if it is ‘necessary’ for the court to ‘resolve the proceedings justly’ [Children and Families Act 2014, s 13(6) ], as a result their evidence and their involvement in the case are likely to be entirely within the four corners of the case. If criticism is to be made, it is likely that the critical matters will have been fully canvassed by one or more of the parties in cross examination. I have raised the question of expert witnesses at this point as part of the strong caveat that I am attempting to attach to this judgment as to the highly unusual circumstances of this case and absence of any need, as I see it, for the profession and the judges to do anything to alter the approach to witnesses in general, and expert witnesses in particular. 102. I should stress that in the previous paragraph I was expressly addressing the approach to be taken to an expert who attends court and gives evidence. I would not wish to be taken as saying anything to add to or alter the approach that is required before criticising a witness who has not been called to give evidence, for which see Munby J’s judgment in Re M (Adoption: International Adoption Trade) [2003] EHC 219 (Fam),[2003] 1 FLR 1111 , paras 111-120.”
