In September 2021, the Court of Appeal reversed the controversial decision of Quincy Bell v Tavistock and Portman NHS Trust in a victory for transgender rights. At first instance, the Divisional Court had set a high legal threshold for transgender children to attain Gillick competence to consent to treatment with puberty blockers – effectively restricting access to treatment for many. On appeal, the Court of Appeal held that children are capable in law of giving valid consent to treatment for gender dysphoria, and court authorisation would not be routinely required before children could access such treatment. This note considers the implications of the Court of Appeal decision for the law on minors and consent to medical treatment in the transgender health context.
