In case the news slipped you by, in April 2025 the Supreme Court ruled that the term ‘s*x’ within the Equality Act 2010 refers strictly to assigned s*x at birth. A ruling which has been increasingly weaponised and used by the growing “gender critical” movement. In May this year, the Equality and Human Rights Commission released its guidance on the case which, as Freedom of Information Act requests uncovering structural gender-critical bias within the commission have since revealed, formalized transgender exclusionary policy in both the workplace and society at large (note: at time of writing the guidance is still to be approved by Parliament).
Under the guise of “proportionate means to a legitimate aim”, transgender protections have been slashed again as the UK continues its slide on LGBTQIA+ rights.
What happens when lived gender is uncoupled from the statutory definition of ‘s*x’?
Let’s take a trans woman who “passes” and is in a relationship with another woman. Now, imagine she is a target for homophobic discrimination or harassment as a result of this relationship. If she files a s*xual orientation claim, a hostile employer can argue that because she is “biologically male”, the relationship is statutorily heteros*xual - erasing the homophobia claim. If she pivots to "Gender Reassignment" protections, the employer escapes liability because the perpetrator was unaware she was transgender.
What does this mean for employers/HR Professionals?
Biological reductionism will fundamentally break reporting mechanisms designed to ensure that minorities are treated fairly. And, yes, this is going to hurt cis women along the way as we watch:
· A false compression of the Gender Pay Gap when pay gap figures hide disparities between men and women.
· A statutory shield created for wage and career suppression, creating a gaping hole in accountability making it much easier for hostile employers to suppress a trans woman’s wages; overlook her for promotions; or make her redundant without triggering red flags on a gender-based equality audit.
· A distortion of grievance data where reductionism blinds HR departments to its scope. Threatening the safety of all women.
· An environment of suspicion that hurts all women. Such as JK Rowling’s promotion of biological policing to foster hyper-surveillance and punish individuals for deviating from patriarchal standards or behaviour and presentation.
Therefore, for businesses, implementing these gatekeeping practices seems like the easiest way to protect themselves from the fallout of the EHRC ruling - right up until they see discrimination claims (which carry uncapped financial awards) from the very people supposedly being protected.
