There's a judgment summary of the decision provided by the Court:
12. The Court of Appeal decided that the declaration made by the Divisional Court covered areas of disputed fact, expert evidence and medical opinion, which were not suitable for determination in judicial review proceedings. The case of Gillick v. West Norfolk and Wisbech Health Authority had decided that it was for doctors, not judges, to decide on the capacity of under-16s to consent to medical treatment. It had been said in R (Burke) v. General Medical Council there were great dangers in a court grappling with issues which were divorced from the factual context that required their determination: “the court should not be used as a general advice centre”. The declaration transgressed these principles.
13. In addition, the Divisional Court was not in a position to give guidance that generalisedabout the capability of persons of different ages to understand what was necessary for them to be competent to consent to the administration of puberty blockers. The guidance would require applications to the court when there was no legal obligation for such an application to be made. It placed patients, parents and clinicians in a difficult position, and should not have been given.
14. The Divisional Court had concluded that Tavistock’s policies and practices were not unlawful and rejected the legal criticism of its materials. In those circumstances, the claim for judicial review should have been dismissed.
15. The Court of Appeal recognised the difficulties and complexities associated with the question of whether under 18s were competent to consent to the prescription of puberty blockers, but it was for clinicians to exercise their judgment knowing how important it was for the patient’s consent to be properly obtained according to the particular individual circumstances. Clinicians would be alive to the possibility of regulatory or civil action which allows the issue of whether consent has been properly obtained to be tested in individual cases.
