Forstater v CGD Europe & Others is the leading authority confirming that gender-critical beliefs can qualify as a protected philosophical belief under section 10 of the Equality Act 2010.
The case is frequently reduced to the proposition that “gender-critical beliefs are protected”. That is correct, but incomplete. The judgment concerned whether the belief itself crossed the threshold for legal protection. It did not establish that every expression, manifestation or consequence of that belief is immune from workplace standards or discrimination law.
For organisations, the central distinction is between holding a protected belief and acting on it in a particular way.
What was Forstater actually about?
Maya Forstater worked under consultancy arrangements with the Centre for Global Development. She expressed views about sex and gender, including the belief that sex is biologically determined and cannot be changed.
After her contract was not renewed, she brought proceedings alleging discrimination because of philosophical belief.
At a preliminary stage, the Employment Tribunal held that the belief was not protected because it was not “worthy of respect in a democratic society”. The Employment Appeal Tribunal overturned that conclusion.
The legal question
The issue was whether the claimant’s belief met the criteria for protection under section 10 of the Equality Act.
The EAT applied the Grainger criteria. A philosophical belief must:
- be genuinely held;
- be a belief rather than an opinion based only on current information;
- concern a weighty and substantial aspect of human life and behaviour;
- attain a sufficient level of cogency, seriousness, cohesion and importance; and
- be worthy of respect in a democratic society, compatible with human dignity and not conflict with the fundamental rights of others.
The final criterion sets a low threshold. A belief will generally be excluded only where it is akin to advocating totalitarianism, violence or the destruction of the rights of others.
What the judgment decided
The EAT held that gender-critical beliefs could satisfy section 10 and were not excluded merely because they could be offensive or distressing to others.
The decision established that:
- gender-critical belief can be a protected philosophical belief;
- unpopular or controversial beliefs are not excluded simply because others strongly disagree;
- the threshold for exclusion under the fifth Grainger criterion is narrow; and
- an employer must not discriminate against someone merely for holding a protected belief.
Belief and manifestation are different
Protection of a belief does not mean unrestricted protection for every manifestation of it.
An employer may still regulate conduct where there is a lawful and proportionate reason. Relevant conduct may include:
- harassment;
- bullying or targeted humiliation;
- discriminatory treatment;
- refusal to perform legitimate duties;
- persistent conduct directed at a colleague after clear boundaries have been set; or
- conduct causing serious operational or safeguarding consequences.
The legal analysis must identify whether action was taken because of the belief itself, or because of the particular way it was expressed or acted upon.
What the judgment did not decide
Forstater did not decide that:
- trans people are outside Equality Act protection;
- deliberate misgendering is always lawful;
- employers cannot require professional and respectful conduct;
- every statement about sex or gender is automatically protected;
- belief protection overrides harassment law; or
- a protected belief gives a person the right to determine another person’s workplace treatment.
Nor did the preliminary appeal determine every later issue in the underlying dispute. It resolved the protected-status question.
Relationship with Higgs
Forstater answers the first question: can the belief qualify for protection?
Higgs v Farmor’s School develops the next stage: when an employer responds to expression linked to a protected belief, was that response objectively justified and proportionate?
Read together, the cases require employers to avoid two errors:
- treating the belief itself as misconduct; and
- assuming that every manifestation must be tolerated regardless of context or impact.
Practical implications for organisations
Employers should:
- identify the belief relied upon before assessing conduct;
- avoid disciplining someone merely for holding or calmly articulating a protected belief;
- investigate the exact words, conduct, context, audience and impact;
- distinguish disagreement, offence and controversy from harassment or unlawful conduct;
- apply conduct standards consistently across viewpoints;
- protect trans staff from discrimination and harassment;
- consider whether a less restrictive response would address the issue; and
- document the actual reason and proportionality behind any action.
A generic statement that conduct was “inappropriate” is unlikely to be enough. The employer should be able to identify the policy, duty, harm or operational consequence relied upon.
A sound way to read the case
Decision-makers should ask:
- What is the protected belief?
- What specific conduct or expression is in issue?
- Was the response triggered by the belief or by its manifestation?
- What evidence of harm or policy breach exists?
- Were comparable cases treated consistently?
- Was the response proportionate?
- Were the rights and dignity of affected trans people also considered?
Key takeaways
- Gender-critical beliefs can be protected under section 10 of the Equality Act.
- The threshold for excluding a belief from protection is narrow.
- Belief protection does not create automatic immunity for conduct.
- Trans people retain protection from discrimination and harassment.
- Employers must separate belief, expression, impact and proportionality.
- A careful, evidenced process is essential.
