Protected philosophical beliefs at work: the law after Miller

Protected philosophical beliefs sit alongside religion in section 10 of the Equality Act 2010, and an employee who is dismissed or disciplined because of one can bring a direct discrimination claim with no cap on compensation. The Employment Appeal Tribunal’s decision in University of Bristol v Miller [2026] EAT 84 is the latest appellate word on where the boundary falls, and this explainer sets out the legal framework as it now stands, drawing only on decided cases.

Who is this guide for?

This guide is written for employment practitioners advising on disciplinary action that touches an employee’s expressed views, for HR teams and in-house counsel designing or applying conduct policies, and for anyone assessing the merits of a belief discrimination claim. It covers the threshold test for protection, the distinction between a belief and its manifestation, and the proportionality exercise an employer’s decision will ultimately be measured against.

What makes a belief protected?

The five criteria come from Grainger plc v Nicholson [2010] ICR 360. A belief qualifies for protection under section 10 where it meets all of the following:

• It is genuinely held.
• It is a belief, and not merely an opinion or viewpoint based on the present state of information available.
• It concerns a weighty and substantial aspect of human life and behaviour.
• It attains a certain level of cogency, seriousness, cohesion and importance.
• It is worthy of respect in a democratic society, is not incompatible with human dignity and does not conflict with the fundamental rights of others.

The case law has repeatedly stressed that these are modest threshold requirements rather than a high bar. A belief need only affect a single but important aspect of a person’s life (Gray v Mulberry Co (Design) Ltd [2019] ICR 175), single-issue beliefs can qualify, and Forstater v CGD Europe [2022] ICR 1 confined the fifth criterion to beliefs akin to totalitarianism, Nazism or the espousal of violence and hatred in the gravest of forms. Beliefs that are offensive, shocking or even disturbing to others remain protected, although their manifestation may justifiably be restricted.

What did the EAT decide in Miller?

The belief pleaded in Miller, and agreed in the list of issues, was that political Zionism as the claimant defined it is inherently racist, imperialistic and colonial, and ought to be opposed. The EAT held that the tribunal had been entitled to find every Grainger criterion satisfied, and it rejected the argument that beliefs connected to political questions fall outside section 10, since Grainger itself contemplated protection for beliefs in political philosophies and Higgs confirms that free speech protection is at its strongest for political speech. A belief informed by academic research is not thereby reduced to mere opinion either.

Two further points from the judgment matter in practice. First, the pleaded belief controls the case: the university’s counsel disavowed any alternative “true belief” at trial, and the EAT refused to let a different characterisation be run on appeal. How the belief is defined at the case management stage will shape everything that follows. Secondly, protection of the belief did not mean the claimant won everything, because the tribunal’s findings that his separate comments about students were culpable, and its 50% contributory fault reduction, both survived. The belief and the conduct surrounding its expression were analysed apart.

Belief versus manifestation: where discipline can still be lawful

The governing framework comes from Page v NHS Trust Development Authority [2021] ICR 941 and Higgs v Farmor’s School [2025] ICR 1172. Treating an employee less favourably because they hold or manifest a protected belief is direct discrimination, but action taken because of an objectionable manifestation, meaning a manifestation to which objection could justifiably be taken, is not treated as being because of the belief, provided the employer’s response is objectively justified. Justification requires that the restriction is prescribed by law, typically through sufficiently precise contractual policies, that it pursues a legitimate aim, and that it is proportionate under the Bank Mellat balancing exercise.

The considerations endorsed in Higgs include the content and tone of the manifestation, its extent and likely audience, the intrusion on the rights of others, any reputational risk, any power imbalance between the worker and those affected, and whether the measure taken was the least intrusive available. Miller shows how the analysis bites both ways: dismissal was disproportionate because even on the employer’s own case the statements were lawful, not antisemitic and incited no violence, yet the tribunal also held that a sanction short of dismissal would have been proportionate, and that finding stood on appeal.

What should employers do before moving to sanction?

• Identify precisely what belief is said to be engaged, and record whether the concern is the belief itself or the specific manner, place and audience of its expression.
• Check what your policies actually prohibit, because the prescribed-by-law limb requires provisions precise enough for the employee to foresee the consequences of their conduct.
• Work through the Bank Mellat questions in writing, including why any lesser sanction would not achieve the legitimate aim.
• Consider each disputed statement separately rather than globally, since tribunals will ask which parts manifested the belief and which went beyond it.
• Keep the decision-maker’s reasoning contemporaneous, because causation is decided on findings about what actually operated on their mind.

What are the common mistakes?

• Assuming a belief is unprotected because it is political, offensive or contested. The threshold is deliberately low.
• Moving straight to dismissal without a documented analysis of lesser sanctions. That gap was decisive in Miller, on both the discrimination and unfair dismissal claims.
• Re-characterising the employee’s “true beliefs” after the event. Concessions made at case management will hold on appeal.
• Treating a finding of protected belief as the end of the analysis. Separable conduct can still ground misconduct findings and substantial contributory fault reductions.
