"The legal burden of establishing the existence of these conditions rests on the applicant for a care order. The general principle is that he who asserts must prove. Generally, although there are exceptions, a plaintiff or applicant must establish the existence of all the preconditions and other facts entitling him to the order he seeks. There is nothing in the language or context of section 31(2) to suggest that the normal principle should not apply to the threshold conditions" 11. "
"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."" 12. "
"27. In the end the Judge must make clear findings on the issues of fact before the Court, resting on the evidence led by the parties and such additional evidence as the Judge may have required in the exercise of his quasi-inquisitorial function. All this is the prelude to a further and fuller investigation of a range of choices in search of the protection and welfare of the children. A positive finding against a parent or both parents does not in itself preclude the possibility of rehabilitation. All depends on the facts and circumstances of the individual case. In that context the consequences of a false positive finding in care proceedings may not be as dire as the consequence of the conviction of an innocent in criminal proceedings. 28. So it by no means follows that an acquittal on a criminal charge or a successful appeal would lead to the absolution of the parent or carer in family or civil proceedings. It is also worth remembering that the decision of the Court of Appeal (Criminal Division) in R v Cannings turned on the very particular facts of that case. 29. In summary the decision of the Court in R v Cannings has no doubt provided a useful warning to judges in care proceedings against ill-considered conclusions or conclusions resting on insufficient evidence. The extent of the retrospective effect remains to emerge. However practitioners should be slow to assume that past cases which have been carefully tried on a wide range of evidence will be readily reopened."
