"[39] I regard the following as trite propositions of law: (1) Experts do not decide cases. Judges do. The expert's function is to advise the judge;(2) The judge is fully entitled to accept or reject expert opinion;(3) If the judge decides to reject an expert's advice, he or she: a. Must have a sound basis upon which to do so; andb. Must explain why the advice is being rejected; (4) Similar considerations arise when a judge prefers one expert's evidence to that of another. Judges must explain why they prefer the evidence of A to that of B"
“35. “When deciding the issue of child arrangements the court should ensure that any order for contact will not expose the child to an unmanageable risk of harm and will be in the best interests of the child. 36. In the light of any findings of fact the court should apply the individual matters in the welfare checklist with reference to those findings; in particular, where relevant findings of domestic violence or abuse have been made, the court should in every case consider any harm which the child and the parent with whom the child is living has suffered as a consequence of that violence or abuse, and any harm which the child and the parent with whom the child is living, is at risk of suffering if a child arrangements order is made. The court should only make an order for contact if it can be satisfied that the physical and emotional safety of the child and the parent with whom the child is living can, as far as possible, be secured before during and after contact, and that the parent with whom the child is living will not be subjected to further controlling or coercive behaviour by the other parent. 37. In every case where a finding of domestic violence or abuse is made, the court should consider the conduct of both parents towards each other and towards the child; in particular, the court should consider (a) the effect of the domestic violence or abuse on the child and on the arrangements for where the child is living; (b) the effect of the domestic violence or abuse on the child and its effect on the child's relationship with the parents; (c) whether the applicant parent is motivated by a desire to promote the best interests of the child or is using the process to continue a process of violence, abuse, intimidation or harassment or controlling or coercive behaviour against the other parent;(d) the likely behaviour during contact of the parent against whom findings are made and its effect on the child; and (e) the capacity of the parents to appreciate the effect of past violence or abuse and the potential for future violence or abuse.”
