Today, the UK Supreme Court delivered a landmark judgment in For Women Scotland Ltd v The Scottish Ministers, clarifying the legal definition of “woman” under the Equality Act 2010 (Equality Act).

Summary of case

The case originated from the Scottish government’s guidance on the Gender Representation on Public Boards (Scotland) Act 2018, which aimed to increase female representation on public sector boards. The guidance included individuals with a Gender Recognition Certificate (GRC), recognising them as women for the purposes of the Act.

For Women Scotland Ltd challenged this interpretation, arguing that it conflated the protected characteristics of sex and gender reassignment under the Equality Act, potentially undermining single-sex spaces and services designated for biological women.

Supreme Court’s judgment

The Supreme Court unanimously ruled that the terms “woman” and “sex” in the Equality Act refer exclusively to biological sex, excluding individuals with a GRC from the legal definition of “woman” concerning certain protections and rights.​

The Supreme Court’s ruling emphasised that the Equality Act’s provisions concerning single-sex services and spaces are intended to protect biological women, stating that the inclusion of individuals with a GRC in the definition of “woman” under the Equality Act would be unlawful, as it would conflict with the statutory protections afforded to biological women in single-sex contexts.​

Implications for employers

This decision has significant implications for the interpretation and application of the Equality Act, particularly concerning the provision of single-sex services and spaces. Public bodies and service providers must now ensure that their policies and practices align with the Supreme Court’s interpretation, which may involve revisiting and potentially revising existing frameworks to maintain compliance.​

1. Employment rights and equal treatment

The Supreme Court’s decision underscores that in the context of employment, “woman” and “man” under the Equality Act are defined by biological sex rather than gender identity or gender reassignment. This has particular implications for single-sex roles, facilities, and protections within the workplace:

• Single-Sex roles and services: employers must carefully review any single-sex roles and ensure that they are providing equal opportunities in line with the law. Certain roles, particularly in sectors such as healthcare, domestic services, and safety, may lawfully be restricted to biological women to protect the rights of women in those spaces.
• Single-sex facilities: employers must also assess the provision of single-sex facilities (e.g., bathrooms and changing rooms) to ensure they are complying with the law. The judgment clarifies that the inclusion of individuals with a GRC in these spaces may not always be lawful, especially where the presence of a biological male could undermine the safety or dignity of others.

2. Transgender employees and discrimination protections

The ruling does not impact the existing protections against discrimination based on gender reassignment. Employers must continue to respect and uphold the rights of transgender employees in the workplace. The Supreme Court reinforced that the Equality Act still protects individuals who have undergone gender reassignment or are in the process of doing so.

However, employers must be vigilant in balancing these protections with the specific rights of biological women in single-sex contexts. This may require thoughtful policies and communication to ensure that the rights of both groups are respected.

3. Duties to prevent discrimination

Employers are under an ongoing obligation to prevent discrimination, harassment, and victimisation based on sex or gender reassignment. The ruling highlights the need for clear, comprehensive policies that outline the organisation’s stance on these issues and how employees are expected to behave in relation to single-sex spaces, roles, and facilities.

Practical steps for employers

• Review and update policies: employers should review their equality, diversity, and inclusion policies in light of this ruling. Policies on single-sex services, workplace roles, and facilities should be clarified to ensure compliance with the ruling while respecting the legal rights of both transgender employees and biological women.
• Conduct risk assessments: employers should conduct a risk assessment regarding the impact of this judgment on single-sex facilities, role definitions, and health and safety practices. For example, an employer may need to assess whether the presence of transgender women (individuals with a GRC) in women-only spaces (e.g., bathrooms and changing areas) could create legal or operational issues for the organisation.
• Training and awareness: employers should invest in training for their HR teams and line managers to ensure they are fully aware of the implications of this ruling. This training should focus on how to support transgender employees while ensuring the rights of all employees are protected in line with the Equality Act.
• Consultation with employees:employers should consider engaging with employees through consultations or surveys to assess their views on the application of single-sex facilities and services in the workplace. A transparent and inclusive approach will help foster understanding and respect among workforces.
• Maintain clear communication channels: employers should ensure that employees understand the organisation’s policies on sex and gender reassignment. Clear communication on how the company will handle requests related to gender identity, as well as access to gender-specific facilities and roles, will help prevent confusion and potential legal challenges.
• Seek legal advice: given the complexity of balancing the rights of transgender employees with those of biological women, employers should consult legal experts to ensure their practices comply with the law. In particular, those in industries with high gender-specific roles (e.g., women’s health and sports) should seek specific legal guidance to ensure compliance with both the Equality Act and the Supreme Court’s ruling.

Conclusion

The Supreme Court’s decision has clarified important legal distinctions regarding biological sex and gender reassignment, with significant implications for employment law. Employers must ensure that their policies and practices are up-to-date, clear, and compliant with this ruling. By balancing the rights of all employees, employers can create a fair, inclusive, and legally compliant workplace.
