Cumbria County Council v M and F (Fact-Finding No. 1 : Unedited)

In fact-finding proceedings concerning suspected child abuse, the local authority bears the burden of proving each allegation on the balance of probabilities. Findings must be based on evidence and proper inferences, not suspicion or speculation, and the court must assess the evidence cumulatively across the whole factual canvas.

Medical evidence is important but does not determine the issue. The court must weigh expert opinion against the other evidence and consider whether the cause of injury may remain unknown. Where a non-accidental injury is established but responsibility cannot safely be attributed to one of several possible perpetrators, the court should not strain to identify an individual. A failure by carers to obtain medical attention may nevertheless be proved separately from responsibility for causing the injury.

The local authority sought care orders for five children following the sudden death of their thirteen-month-old sibling, P. Post-mortem examination disclosed healing fractures to P’s right leg and injuries to the anal region. The parents denied causing any harm.

The principal issues were whether either parent caused the leg fractures, whether they failed to obtain medical attention, whether the father perpetrated a penetrative anal assault, and whether the assault caused P’s death. The court also considered the effect of serious investigative delays and deficiencies on the reliability of the fact-finding process.

1. Applicable approach. The burden remained on the local authority and the standard was the balance of probabilities. Findings had to be based on evidence and proper inferences, with the evidence assessed both individually and cumulatively. Expert evidence was to be considered in the context of the whole case; the court, not the experts, made the final decision. The possibility of an unknown cause had to be included in the evaluation where appropriate.
2. Leg fractures. The fractures were unusual and required significant force, but were not specific to non-accidental injury. Because the investigation had not fixed the injury in time or place, the court could not determine whether it was inflicted, accidental, or caused by a third party. The local authority therefore failed to prove that either parent caused the fractures. It did prove, however, that the parents failed to obtain medical care for symptoms they knew or ought to have known indicated a serious injury. That finding was separate and crossed the threshold for statutory intervention.
3. Anal injuries. The court accepted that the injuries were genuine and resulted from penetrative trauma from outside the body. The father’s account was unconvincing. Although significant forensic evidence was absent, those absences affected the probabilities but did not exonerate him. The evidence established that the father perpetrated a penetrative anal assault, using his penis or another unidentified object.
4. Cause of death. The court found that P died during or shortly after the assault, but the medical cause of death remained unascertained. The suggested mechanisms, including suffocation and reflex cardiac arrest, were possible but insufficiently proved. The court declined to find that the assault caused death by any particular mechanism.
5. The court invited submissions on the further course of the proceedings and directions.

First-instance fact-finding judgment. No appeal or earlier decision is stated in the judgment.
