A consultant psychiatrist has brought an employment tribunal claim against Greater Manchester Mental Health NHS Foundation Trust, alleging the trust dismissed her safeguarding concerns over a policy allowing trans women to be admitted to female psychiatric wards.

The claimant, referred to in proceedings as Dr A, alleges that vulnerable female patients, including survivors of sexual violence, have been detained on psychiatric wards under policies she describes as unlawful. She claims these policies allow biologically male individuals who identify as women to access female wards and associated intimate facilities, including showers.

Dr A's case centres on the Supreme Court's ruling in April 2025, which confirmed that the definition of sex in the Equality Act 2010 refers to biological sex. She says she expected Greater Manchester Mental Health, known as GMMH, to bring its policies into line with this ruling.

According to her claim, repeated requests for clarity on how the trust intended to respond were met with delay and resistance. She alleges she was told the ruling might potentially be challenged in the European Court of Human Rights, and that its implications might conflict with positions held by professional bodies such as the British Medical Association.

Dr A's legal position rests on her stated belief that sex is biological, binary and immutable, and that female patients and staff are entitled to single-sex wards, toilets and changing facilities on that basis. She argues these beliefs are protected under the Equality Act 2010, and claims she experienced workplace detriment as a result of expressing them.

According to the claim, as of 12 August 2026, GMMH's Delivering Single-Sex Accommodation policy continued to state that trans patients should be accommodated according to how they present, including in relation to toilet and bathing facilities. Dr A alleges that sixteen months after the Supreme Court's ruling, the trust had neither amended its key policies nor stopped admitting biologically male patients to female psychiatric wards.

She further alleges that the trust's overall handling of her concerns, including her grievance and subsequent appeal, amounted to harassment and either direct or indirect discrimination connected to her gender-critical beliefs, and that this created what she describes as a hostile and humiliating environment. She is being supported in bringing her claim by the Christian Legal Centre.

Dr A says she first raised concerns about the trust's policies in 2023, initially with its equality, diversity and inclusion team, and later directly with senior GMMH executives following the Supreme Court's decision in 2025.

Through her tribunal claim, Dr A is asking the tribunal to determine whether the trust's conduct amounted to an ongoing course of unlawful behaviour. She is seeking compensation and other remedies under the Equality Act 2010, including a recommendation that the trust reserve female toilets specifically for biological women.

Speaking about her decision to pursue legal action, Dr A said she had felt increasingly alone in raising her concerns, and that while she was repeatedly told the issue required nuance and case by case consideration, she felt there was an unwillingness to acknowledge that many women experience genuine distress at the presence of men in women only spaces, particularly within hospital settings. She said bringing legal proceedings had not been a decision taken lightly, but one she felt necessary given what she described as the urgent need for lawful policies and government action.

Andrea Williams, chief executive of the Christian Legal Centre, commented on the case, describing it as exposing the consequences of an NHS trust losing sight of what she termed biological reality. She noted that women admitted to psychiatric hospitals are often in a state of extreme vulnerability, with some having experienced sexual violence, domestic abuse or other serious trauma, and argued that their need for privacy, dignity and safety should not be set aside. She said it was difficult to comprehend how, in an environment where safeguarding should be paramount, biological sex could effectively be disregarded when it came to access to female only spaces.

The case forms part of a wider pattern of legal challenges and policy disputes across NHS trusts and other public bodies as organisations work through the practical implications of the Supreme Court's ruling on the legal definition of sex.
