“45. First, the burden of proof lies at all times with the local authority. 46. Secondly, the standard of proof is the balance of probabilities. 47. Third, findings of fact in these cases must be based on evidence, including inferences that can properly be drawn from the evidence and not on suspicion or speculation. I have borne this principle in mind throughout this hearing. 48. Fourthly, when considering cases of suspected child abuse the court must take into account all the evidence and furthermore consider each piece of evidence in the context of all the other evidence. The court invariably surveys a wide canvas. A judge in these difficult cases must have regard to the relevance of each piece of evidence to other evidence and to exercise an overview of the totality of the evidence in order to come to the conclusion whether the case put forward by the local authority has been made out to the appropriate standard of proof. 49. Fifthly, amongst the evidence received in this case, as is invariably the case in proceedings involving allegations of nonaccidental head injury, is expert medical evidence from a variety of specialists. Whilst appropriate attention must be paid to the opinion of medical experts, those opinions need to be considered in the context of all the other evidence. It is important to remember that the roles of the court and the expert are distinct and it is the court that is in the position to weigh up the expert evidence against its findings on the other evidence. It is the judge who makes the final decision. 50. Sixth, cases involving an allegation of non-accidental injury often involve a multi-disciplinary analysis of the medical information conducted by a group of specialists, each bringing their own expertise to bear on the problem. The court must be careful to ensure that each expert keeps within the bounds of their own expertise and defers, where appropriate, to the expertise of others. 51. Seventh, the evidence of the parents and any other carers is of the utmost importance. It is essential that the court forms a clear assessment of their credibility and reliability. 52. Eighth, it is common for witnesses in these cases to tell lies in the course of the investigation and the hearing. The court must be careful to bear in mind that a witness may lie for many reasons, such as shame, misplaced loyalty, panic, fear and distress, and the fact that a witness has lied about some matters does not mean that he or she has lied about everything (see R v Lucas[1981] QB 720 ). 53. Ninth, as observed by Dame Elizabeth Butler-Sloss P in an earlier case “The judge in care proceedings must never forget that today's medical certainty may be discarded by the next generation of experts or that scientific research would throw a light into corners that are at present dark.” 54. This principle, inter alia, was drawn from the decision of the Court of Appeal in the criminal case of R v Cannings[2004] EWCA 1 Crim. In that case a mother had been convicted of the murder of her two children who had simply stopped breathing. The mother's two other children had experienced apparent life-threatening events taking a similar form. The Court of Appeal Criminal Division quashed the convictions. There was no evidence other than repeated incidents of breathing having ceased. There was serious disagreement between experts as to the cause of death. There was fresh evidence as to hereditary factors pointing to a possible genetic cause. In those circumstances, the Court of Appeal held that it could not be said that a natural cause could be excluded as a reasonable possible explanation. In the course of his judgment, Judge LJ (as he then was) observed: “What may be unexplained today may be perfectly well understood tomorrow. Until then, any tendency to dogmatise should be met with an answering challenge.””
“26. In these difficult and worrying cases where the court has, as Lord Nicholls has said, to recognise and have regard to the differing interests of the adults and the child, Parliament has provided a two limb threshold which requires to be satisfied before the court has the right to consider the welfare of the child. The first is met in this appeal since the child was injured and suffered significant harm. In relation to the second limb, the attributable condition, it seems to me that the two most likely outcomes in 'uncertain perpetrator' cases are as follows. The first is that there is sufficient evidence for the court positively to identify the perpetrator or perpetrators. Second, if there is not sufficient evidence to make such a finding, the court has to apply the test set out by Lord Nicholls as to whether there is a real possibility or likelihood that one or more of a number of people with access to the child might have caused the injury to the child. For this purpose, real possibility and likelihood can be treated as the same test. As Lord Nicholls pointed out in re O and N (Minors); re B (Minors) (above) the views and indications that the judge at the first part of a split trial may be able to set out may be of great assistance at the later stage of assessment and the provision of the protection package for the injured child. I would therefore formulate the test set out by Lord Nicholls as, "Is there a likelihood or real possibility that A or B or C was the perpetrator or a perpetrator of the inflicted injuries?". There may perhaps also be the third possibility that there is no indicator to help the court decide from whom the risk to the child may come, in which eventuality it would be very difficult for the local authority and for the court to assess where the child might be at most risk.”
“Within that list of factors, although the judge does not expressly prioritise them, the finding that Mr C lied about the quietness in his flat that night is given the greatest prominence in this section of the judge's analysis. A family court, in common with a criminal court, can rely upon a finding that a witness has lied as evidence in support of a primary positive allegation. The well-known authority is the case of R v Lucas (R)[1981] QB 720 in which the Court of Appeal Criminal Division, after stressing that people sometimes tell lies for reasons other than a belief that the lie is necessary to conceal guilt, held that four conditions must be satisfied before a defendant's lie could be seen as supporting the prosecution case as explained in the judgment of the court given by Lord Lane CJ: "To be capable of amounting to corroboration the lie told out of court must first of all be deliberate. Secondly it must relate to a material issue. Thirdly the motive for the lie must be a realisation of guilt and a fear of the truth. The jury should in appropriate cases be reminded that people sometimes lie, for example, in an attempt to bolster up a just cause, or out of shame or out of a wish to conceal disgraceful behaviour from their family. Fourthly the statement must be clearly shown to be a lie by evidence other than that of the accomplice who is to be corroborated, that is to say by admission or by evidence from an independent witness." The decision in R v Lucas has been the subject of a number of further decisions of the Court of Appeal Criminal Division over the years, however the core conditions set out by Lord Lane remain authoritative. The approach in R v Lucas is not confined, as it was on the facts of Lucas itself, to a statement made out of court and can apply to a "lie" made in the course of the court proceedings and the approach is not limited solely to evidence concerning accomplices. In the Family Court in an appropriate case a judge will not infrequently directly refer to the authority of R v Lucas in giving a judicial selfdirection as to the approach to be taken to an apparent lie. Where the "lie" has a prominent or central relevance to the case such a selfdirection is plainly sensible and good practice. One highly important aspect of the Lucas decision, and indeed the approach to lies generally in the criminal jurisdiction, needs to be borne fully in mind by family judges. It is this: in the criminal jurisdiction the "lie" is never taken, of itself, as direct proof of guilt. As is plain from the passage quoted from Lord Lane's judgment in Lucas, where the relevant conditions are satisfied the lie is "capable of amounting to a corroboration". In recent times the point has been most clearly made in the Court of Appeal Criminal Division in the case of R v Middleton [2001] Crim.L.R. 251. In my view there should be no distinction between the approach taken by the criminal court on the issue of lies to that adopted in the family court. Judges should therefore take care to ensure that they do not rely upon a conclusion that an individual has lied on a material issue as direct proof of guilt.”
