J (Transgender: Puberty Blocker and Hormone Replacement Therapy), Re

In a novel and sensitive area, the court should develop the common law incrementally and decide only issues necessary to resolve a live dispute. It should avoid academic declarations or general guidance that trespass on Parliament’s role. A young person’s capacity to consent to medical treatment is decision-specific and time-specific. For a person aged 16 or over, Family Law Reform Act 1969, section 8 ordinarily makes that person’s consent effective, subject to the Mental Capacity Act 2005 and the High Court’s inherent jurisdiction. The court may nevertheless need to scrutinise carefully any proposed treatment by an offshore, online and unregulated provider, particularly where the evidence raises serious safety concerns.

The proceedings concerned J, aged 16½, who had been assigned female at birth and regarded himself as male. He had received testosterone prescribed through the offshore online provider Gender GP. His father applied under section 8 of the Children Act 1989 and the inherent jurisdiction, seeking to prevent further puberty-blocker or cross-sex hormone treatment without court approval and inviting the court to determine wider questions concerning capacity, diagnosis, best interests and parental consent.

By the final hearing, the parties accepted that J should undergo an assessment by a new London clinic, Gender Plus, and further testosterone from Gender GP had been deferred. The central issue was whether the court should determine the wider legal questions immediately or limit its decision to the agreed interim plan.

1. Disposition. The court endorsed the agreed or accepted plan for J to undergo an assessment by Gender Plus over approximately six months. No final determination was made on capacity to consent to further treatment, the proposed exercise of the inherent jurisdiction, the father’s wider legal case, or general guidance.
2. Necessary decision-making. The court should limit its involvement to decisions currently required. In a novel and sensitive area, the common law should develop incrementally on a case-by-case and decision-by-decision basis. The court should not be drawn into academic discourse or lay down law beyond what is necessary to resolve the current dispute, since that risks trespassing on Parliament’s role.
3. Capacity and consent framework. Capacity is decision-specific and time-specific. For a person aged 16 or over, section 8 of the Family Law Reform Act 1969 ordinarily makes consent to medical treatment effective as if the person were of full age, unless the person lacks capacity under section 2(1) of the Mental Capacity Act 2005. The inherent jurisdiction remains available in an appropriate case, consistently with Re W, where the consequences of the decision are sufficiently grave.
4. Preliminary indication. If further treatment from Gender GP became live, the court would need to consider carefully J’s capacity to consent to that particular treatment and whether the inherent jurisdiction should prohibit it. The available evidence gave rise to very significant concerns about cross-hormone treatment from an offshore, online, unregulated private clinic, and additional serious concerns about Gender GP’s assessment, prescribing and safety practices. Any renewed proposal would require a detailed account from the clinic of its proposed assessment and treatment.
5. The court stated that any other court dealing with Gender GP should proceed with extreme caution before approving or endorsing treatment prescribed by that clinic.

This was a first-instance decision in proceedings under section 8 of the Children Act 1989 and the inherent jurisdiction of the High Court. The judgment records the father’s application and the parties’ agreed interim position, but no earlier judgment is stated.
