The British record

The country that changed its mind, on paper

No other country has reversed course on youth gender medicine as publicly as Britain. The Cass Review, the closure of the Tavistock service, the end of routine puberty blockers, the Supreme Court on the meaning of sex: each of those is a document with a date. This site holds them, quoted and linked.

The Cass Review: findings and recommendations

The Cass Review was commissioned by NHS England after serious concerns emerged about the capacity, clinical model and evidence base of the national service for children and young people presenting with gender-related distress. For many years, the Tavistock’s Gender Identity Development Service, usually known as GIDS, was the sole national NHS specialist service in England. Referrals rose sharply and the profile of those referred changed substantially, with a marked increase in adolescent girls and young people with complex mental-health, neurodevelopmental and safeguarding needs.

Tavistock GIDS: rise, whistleblowers and closure

The Gender Identity Development Service (GIDS), run by the Tavistock and Portman NHS Foundation Trust, was for many years England’s sole national specialist service for children and young people experiencing gender-related distress. Its centralised structure meant that referrals from across England, and at points from other UK nations, were channelled towards one provider and associated satellite clinics.

For Women Scotland and the meaning of sex in the Equality Act

De zaak van For Women Scotland draaide formeel niet om toiletten, kleedkamers of ziekenhuisafdelingen. Zij ging over de vraag wie als “woman” telt bij het streven naar een betere vertegenwoordiging van vrouwen op Schotse publieke besturen. Maar de juridische vraag was veel breder: wat betekenen de woorden “sex”, “man” en “woman” in de Equality Act 2010, gezien section 9 van de Gender Recognition Act 2004?

The UK conversion-practices ban and exploratory therapy

Successive UK governments have struggled to legislate because there is broad agreement on one proposition but sharp disagreement on another. Few dispute that violence, threats, coercion, forced confinement, assault, sexual abuse, forced marriage, exorcism involving abuse, or attempts to compel a person to renounce same-sex attraction should be prohibited. Much of that conduct is already criminal under existing law. The difficult question is whether, and how, criminal law should regulate conversations, counselling, prayer, family pressure and therapeutic work concerning sexuality or gender iden

Schools guidance on gender-questioning children in England

For several years, English schools have faced competing requests and duties when a child says that they wish to be treated as the opposite sex, changes their name or pronouns, or seeks access to opposite-sex facilities. The Department for Education’s answer has now moved from proposed non-statutory guidance to safeguarding guidance which schools and colleges must have regard to.

Keira Bell, Bell v Tavistock and detransition in the UK

Keira Bell became the public face of a legal challenge to the former Tavistock and Portman NHS Foundation Trust’s Gender Identity Development Service (GIDS). Bell had received puberty-suppressing medication as an adolescent, later took testosterone and underwent surgery, and subsequently detransitioned. Together with “Mrs A”, the mother of a teenage girl, she sought judicial review of the lawfulness of the consent arrangements used when children and young people were referred for puberty blockers.

REPATH LAUNCH

Genspect formally launches REPATH — its Re-psychopathologisation Campaign — on 15 September 2026, with hosts Stella O'Malley and Mia Hughes setting out the case for replacing automatic affirmation with thorough psychiatric assessment and differential diagnosis. The campaign's core demand mirrors the central recommendation of the Cass Review: that gender dysphoria in young people should receive the same rigorous clinical evaluation as any other complex mental health presentation, not an administrative pathway insulated from standard diagnostic scrutiny.

Why the documents matter here

British argument about gender is unusually well documented and unusually badly reported. Claims about what the Cass Review found, what the Supreme Court decided or what the schools guidance permits are repeated on both sides by people who have not read them. Each dossier quotes the document, gives the paragraph, and links the original so that the reader can check.
