Factual and Procedural Background
The appeal concerns a nine-month-old boy, referred to as the Child, who suffers from a rare and severe genetic mitochondrial disease causing progressive and irreversible brain damage and multiple organ system dysfunction. Since early October 2016, the Child has been an inpatient at The Hospital, dependent on mechanical ventilation and intensive care. The Child's parents, united in their desire to preserve his life and improve his condition, identified an alternative treatment known as nucleoside therapy, available in the USA, which they believed might slow or halt the progression of the disease.
The treating clinicians at The Hospital, after observing a significant decline in the Child’s brain function, concluded that nucleoside therapy would offer no benefit and that continuing life-sustaining treatment was not in the Child's best interests. The Hospital applied to the Family Division of the High Court seeking declarations that it was lawful and in the Child’s best interests to withdraw artificial ventilation, provide only palliative care, and not to administer nucleoside therapy.
The High Court, presided over by Judge Francis, held that nucleoside therapy was futile and that withdrawing life-sustaining treatment was in the Child's best interests. The Child’s parents appealed this decision, seeking permission to arrange for the Child to receive nucleoside therapy abroad. Pending the appeal, The Hospital maintained current treatment. The Court of Appeal heard the appeal on 22 May 2017.
Legal Issues Presented
- Whether the High Court erred in law by applying the ordinary best interests test rather than a threshold of "significant harm" when deciding between two viable treatment options.
- Whether the High Court had jurisdiction to grant declarations effectively preventing the Child’s parents from arranging alternative treatment abroad.
- Whether the High Court made errors in its evaluation of the Child’s neurological condition and the characterization of nucleoside therapy as futile.
- Whether the Human Rights of the Child and the parents under Articles 2, 5, and 8 of the European Convention on Human Rights were adequately considered.
- Whether procedural fairness was compromised by late disclosure of documents.
Arguments of the Parties
Appellant's Arguments
- The appellants argued for the recognition of two categories of medical treatment cases: Category 1 (ordinary best interests test) and Category 2 (cases involving a choice between two viable treatments), where parental autonomy should prevail unless the alternative treatment risks causing the child significant harm.
- They contended that the High Court erred by not applying the "significant harm" threshold derived from Re King and related authorities, which limits court interference with parental decisions on treatment.
- The appellants asserted the court lacked jurisdiction to prevent the Child's parents from arranging nucleoside therapy abroad, as The Hospital exceeded its statutory powers by seeking declarations that effectively acted as an injunction.
- They challenged the judge’s findings on neurological evidence, particularly the characterization of nucleoside therapy as futile, and argued that the judge failed to properly weigh the presumption of sanctity of life and the parents’ evidence of the Child’s responsiveness.
- They raised procedural unfairness due to late disclosure of documents.
Respondents' Arguments
- The Hospital and the Child’s Guardian submitted that the ordinary best interests test applies universally in medical treatment disputes involving children, regardless of alternative treatment options.
- They argued that the "significant harm" threshold applies only in care proceedings involving local authorities and does not restrict the court’s inherent jurisdiction in medical treatment cases.
- The respondents maintained that the declarations sought were necessary to protect the Child’s best interests and that The Hospital acted within its powers by applying for a court determination.
- They emphasized the unanimous expert medical opinion that nucleoside therapy was futile and would prolong suffering without benefit.
- They denied that any procedural unfairness affected the fairness of the proceedings.

Application by the Court |
| Aintree University Hospitals NHS Foundation Trust v James [2014] AC 591 |
Clarifies that the legal concept of futility in treatment decisions differs from the medical definition; the law requires a broader best interests assessment beyond just medical benefit. |
The court applied this distinction to uphold the High Court’s finding that nucleoside therapy was futile in law as it offered no effective benefit to the Child. |
| Re King [2014] EWHC 2964 (Fam) |
Suggested a threshold of "significant harm" before the court may interfere with parental choice of treatment where two viable treatment options exist. |
The court held that Re King did not establish a new legal test applicable beyond its specific context and did not displace the best interests test in medical treatment cases. |
| Re J (a minor) (wardship: medical treatment) [1991] Fam 33 |
Establishes that the court’s parens patriae jurisdiction overrides parental decisions when necessary, with the best interests of the child as paramount. |
The court reaffirmed that the ultimate decision on medical treatment lies with the court, not parents, and no additional threshold such as significant harm applies. |
| Re Z (Identification: Restrictions of publication) [1997] Fam 1 |
The court exercises independent judgment even when the decision of devoted and responsible parents differs. |
The court relied on this principle to reject the appellants’ argument that parental decisions should be determinative absent significant harm. |
| Re T (Wardship: Medical Treatment) [1997] 1 WLR 242 |
The child’s welfare is paramount; parental reasonableness is a relevant but not determinative factor in medical treatment decisions. |
The court applied this principle, emphasizing the judge’s independent assessment of best interests over parental preference. |
| Barnett London Borough Council v AL [2017] EWHC 125 (Fam) |
Local authorities require leave under Children Act 1989 s.100(4) to apply under inherent jurisdiction, with a threshold of likely significant harm. |
The court distinguished this as applying only to local authorities, not to hospitals or other parties in medical treatment cases. |
| Portsmouth NHS Trust v W [2005] EWHC 2293 (Fam) |
Doctors may refuse treatment they consider inimical but should not prevent others from providing treatment they consider appropriate. |
The court noted this principle but confirmed the ultimate decision rests with the court’s best interests determination. |
| Broadmoor Special Hospital Authority v Robinson [2000] QB 775 |
Public bodies may only act within the scope of their statutory powers. |
The appellants’ argument that The Hospital acted ultra vires was rejected as the court’s order arose from judicial determination, not unilateral hospital action. |
Court's Reasoning and Analysis
The Court of Appeal undertook a detailed review of the factual and medical evidence, the legal principles governing medical treatment disputes involving children, and the arguments advanced by the parties. The court emphasized the well-established legal framework that the paramount consideration is the child’s best interests, which encompass medical, emotional, and welfare factors.
The appellants’ proposed distinction between two categories of cases and the imposition of a "significant harm" threshold before the court may override parental choice was rejected. The court found that this proposition had no foundation in established law and was inconsistent with authoritative decisions, including Re J and Re T, which confirm the court’s independent parens patriae jurisdiction to make medical treatment decisions based solely on best interests.
The court noted that Re King, relied upon by the appellants, was a unique case with agreed treatment plans and did not establish a binding legal test applicable to disputes over viable alternative treatments. The "significant harm" threshold applies in the context of local authority care proceedings, not to medical treatment decisions brought by hospitals or other parties under the inherent jurisdiction.
The court carefully considered the medical evidence, including the unanimous expert opinion that nucleoside therapy was futile and would not benefit the Child’s condition, and that the Child was suffering significant pain and distress. The sole dissenting expert acknowledged the absence of clinical evidence and considered any potential benefit to be vanishingly small.
The court found no error in the High Court’s evaluation of the neurological evidence or the characterization of nucleoside therapy as futile. The judge’s balancing of benefits and burdens was consistent with the law, and the presumption in favor of preserving life was outweighed by the evidence of futility and suffering.
The court also rejected the argument that The Hospital acted beyond its powers, noting that the declarations and any injunction would be court orders made after full consideration of the Child’s best interests, not unilateral hospital actions.
Finally, the court found no procedural unfairness that would justify setting aside the judgment.
Holding and Implications
The Court of Appeal DISMISSED THE APPEAL, upholding the High Court’s declarations that it was lawful and in the Child’s best interests to withdraw artificial ventilation, provide palliative care only, and not to undergo nucleoside therapy.
The decision confirms the continued application of the best interests test as the sole and paramount legal standard in medical treatment disputes involving children, regardless of whether parents propose alternative treatments. It rejects the creation of a new legal threshold based on "significant harm" for parental autonomy in such cases.
The ruling underscores the court’s independent parens patriae jurisdiction to determine the appropriate medical treatment for children and affirms that parental preference, while respected and considered, is not determinative if it conflicts with the child’s best interests as assessed by the court.
No new precedent was set beyond clarifying that Re King does not establish a distinct legal category or threshold applicable to medical treatment disputes. The direct effect is that the Child’s parents are not entitled to arrange nucleoside therapy abroad against the court’s ruling, and The Hospital may lawfully withdraw life-sustaining treatment.
