  Mrs Justice Theis DBE stated at paragraph 7 of her judgment:

  ‘All of the advocates have conducted this hearing to the highest standard; in particular Mrs Crowley Q. C., on behalf of the mother, for her detailed, well targeted and extremely effective cross examination which turned the case round from what it first appeared to be on paper. This case has illustrated the vital importance of advocates who are experienced in undertaking this work and the value of the forensic process. Without that expertise and this process the outcome in this case could have been very different, which would have been detrimental to E's welfare.’
