X v The Sydney Children's Hospitals Network

The case of X v The Sydney Children's Hospitals Network concerned an application by The Sydney Children's Hospitals Network (the Network) to the Supreme Court of New South Wales for consent to administer blood transfusions to a minor, X, who was a patient. X, a mature minor, was a Jehovah's Witness and had refused consent to blood transfusions on religious grounds. The Network sought to override X's refusal, arguing it was in X's best interests.

The primary legal issues before the Court of Appeal were whether the Supreme Court, exercising its parens patriae jurisdiction, possessed the power to consent to medical treatment for a mature minor who was capable of consenting to such treatment, and whether this power extended to overriding a minor's refusal of treatment on religious grounds. The Court also considered whether section 174 of the Children and Young Persons (Care and Protection) Act 1998 (NSW) constituted a code that excluded the Court's inherent jurisdiction in such matters.

The Court of Appeal affirmed the principles governing the treatment of mature minors, acknowledging their capacity to make informed decisions about their medical care. It was held that while the court's parens patriae jurisdiction allows it to intervene in the best interests of a child, this power is not absolute and must be exercised with caution, particularly when a mature minor has expressed a clear and informed refusal of treatment. The Court found that section 174 of the Children and Young Persons (Care and Protection) Act 1998 (NSW) did not extinguish the court's inherent jurisdiction to consent to treatment in exceptional circumstances, but it did not grant the court a broad power to override the refusal of a competent minor. The appeal was otherwise dismissed, with the Court varying an existing order to limit its duration.
