The recent county court judgment in Haynes v The English Blackball Pool Association offers a topic legal precedent regarding transgender discrimination in the context of the Equality Act 2010.
This case, being the first of its kind since the Supreme Court’s definitive ruling in For Women Scotland (FWS) v Scottish Ministers, provides critical guidance for employers seeking to ensure their policies align with current legal interpretations.
Case Summary
The case concerned the English Blackball Pool Association’s policy of excluding transgender women (i.e., individuals who are biologically male) from the female category of competition.
The Claimant, a transgender woman holding a Gender Recognition Certificate, alleged that this exclusion constituted direct gender reassignment discrimination.
The court dismissed the claim, referencing the Supreme Court’s decision in For Women Scotland. It found that the term ‘sex’ in the Equality Act 2010 refers to biological sex. Consequently, the correct comparator for the Claimant was a biological male without the protected characteristic of gender reassignment.
As such, a person would also be excluded from the female category; therefore, the Claimant could not demonstrate that she had been subjected to different treatment on the grounds of her protected characteristic.
The Definition of ‘Sex’ Under the Equality Act 2010

As a result of the Supreme Court ruling in For Women Scotland, the legal definition of ‘sex’ in the Equality Act 2010 is interpreted as biological sex. This means that, in law, a Gender Recognition Certificate does not override biological sex for the purposes of the Equality Act.
This interpretation provides a clear foundation for employers when developing policies that may differentiate between individuals based on biological sex.
Key Implications for Employers
While this case arose in a sporting context, the principles are directly applicable to the workplace. Employers should consider the following implications for their own policies and practices:
1. Legality of Single-Sex Activities and Facilities:
The court confirmed that the sport of pool is a “gender-affected activity,” allowing for separate competitions for men and women where this is necessary to ensure fair competition (s195 Equality Act 2010).
Guidance: Employers may lawfully organise single-sex activities or provide single-sex facilities (e.g., changing rooms) where there is a clear, defensible reason for doing so. This justification must be rooted in a legitimate aim such as privacy, dignity, or fairness.

2. Justification and Proportionality of Policies:
The pool association’s policy was not found to be discriminatory because it was deemed a “proportionate means of achieving the legitimate aim” of “promoting the integrity of the game through fairness of competition and diversity through inclusion of females in the game of pool” (Schedule 3 para 28 Equality Act 2010).
Guidance: Any policy that differentiates on the basis of biological sex must be supported by a clearly articulated, legitimate business aim. It is imperative that the policy is a proportionate and measured response to that aim.
Employers must thoroughly document the rationale behind such policies to withstand legal challenge.
3. Policy Review and Professional Development:
This decision underscores the importance of regularly reviewing and updating company policies to reflect evolving legal standards.
Guidance: Employers are advised to conduct a comprehensive review of all equality and diversity policies, with particular attention to areas concerning single-sex activities, facilities, or specific roles.
Furthermore, providing management and HR personnel with training on these nuanced issues is crucial to mitigate legal risk and ensure consistent application of company policy.
Commentary from Roy Magara
This judgment provides valuable clarification for employers navigating complex issues of equality law.
It reinforces that while the Equality Act promotes inclusion, legitimate aims such as fairness and safety can justify distinctions based on biological sex, provided such measures are proportionate.
Importantly, this case highlights that organisations must balance inclusion with fairness, safety, and legal compliance, ensuring all policies are proportionate, transparent, and justifiable under the Equality Act.
This case serves as a crucial reminder for organisations to review their policies, ensuring that any differentiations are underpinned by a well-documented, legitimate objective and are implemented in a proportionate manner.
