“82. First, the burden of proof lies with the local authority. It is the local authority that brings these proceedings and identifies the findings that they invite the court to make. Therefore, the burden of proving the allegations rests with them. 83. Secondly, the standard of proof is the balance of probabilities: Re B (Children) [2008] UKHR 35. If the local authority proves a fact on the balance of probabilities, this court will treat that fact as established and all future decisions concerning M's future will be based on that finding. Equally, if the local authority fails to prove any allegation, the court will disregard that allegation completely. In her written submissions on behalf of the local authority, Miss Bretherton contended that the court should apply the principle that “the more serious the allegation the more cogent is the evidence required to overcome the unlikelihood of what is alleged and thus to prove it.”
“70 I would announce loud and clear that the standard of proof in finding the facts necessary to establish the threshold under s.31(2) or the welfare considerations of the 1989 Act is the simple balance of probabilities — neither more nor less. Neither the seriousness of the allegation nor the seriousness of the consequences should make any difference to the standard of proof to be applied in determining the facts. The inherent probabilities are simply something to be taken into account, where relevant in deciding where the truth lies. “the more serious the allegation the more cogent is the evidence required to overcome the unlikelihood of what is alleged and thus to prove it.” “70 I would announce loud and clear that the standard of proof in finding the facts necessary to establish the threshold under s.31(2) or the welfare considerations of the 1989 Act is the simple balance of probabilities — neither more nor less.

A child may find her relationship with her family seriously disrupted or she may find herself still at risk of suffering serious harm. A parent may find his relationship with his child seriously disrupted or he may find himself still at liberty to maltreat this or other children in the future. 72. As to the seriousness of the allegation, there is no logical or necessary connection between seriousness and probability.”
“The assessment of credibility generally involves wider problems than mere ‘demeanour’ which is mostly concerned with whether the witness appears to be telling the truth as he now believes it to be. With every day that passes the memory becomes fainter and the imagination becomes more active. The human capacity for honestly believing something which bears no relation to what actually happened is unlimited. Therefore, contemporary documents are always of the utmost importance: Onassis and Calogeropoulos v Vergottis[1968] 2 Lloyd’s Rep 403 , per Lord Pearce; A County Council v M and F[2011] EWHC 1804 (Fam) [2012] 2 FLR 939 at paras [29] and [30].”
