1 The Equality Act 2010 was given royal assent on 8 April 2010, but it is not expected to come into force until October 2010. As its provisions do not materially change the law on the issues discussed, this article will refer to the 2003 Regulations in force at the time or writing.

2 Provisions protecting against discrimination on grounds of religion and political opinion were already in force in Northern Ireland (Fair Employment and Treatment (Northern Ireland) Order 1998).

3 For example Art 14 ECHR, Art 13 Treaty of Rome, Art 21 EU Charter of Fundamental Rights, and also the constitutions of South Africa, Canada, US and India (Arts 25–28, Constitution of India).

4 For example A McColgan, ‘Class wars? Religion and (in)equality in the workplace’ (2009) 38 ILJ 1, A Lester and P Uccellari ‘Extending the equality duty to religion, conscience and belief: Proceed with caution’, (2008) EHRLR 567.

It could also cause difficulties in other cases, for example if individuals are unable to formulate their beliefs in a sufficiently clear way because of a lack of capacity for reasons such as youth or disability.

17 Protection for political opinion can also be found in Belgium, Cyprus Czech Republic, Denmark, Estonia, Finland, France, Hungary, Italy, Latvia, Luxembourg, Malta, the Netherlands, Poland, Portugal, Slovenia and Spain. The remaining Member States do not provide specific protection for political opinion.

18 Nicholson v Grainger UKEAT/0219/09 at para 28. However, note that a later Employment Tribunal decision (Kelly v Unison 28 Jan 2010, ET/2203854-57/08) has confirmed that the Regulations do not protect all political beliefs and opinions, and in particular they do not protect beliefs based on Marxism/Trotskyism and the Socialist Party.

19 Handyside v United Kingdom, (1976) 1 EHRR 737.

20 For example in R (Williamson) v Secretary of State for Education and Employment [2005] UKHL 15. Lord Walker stated ‘in matters of human rights the court should not show liberal tolerance only to tolerant liberals’ at para 60 also discussed by Christopher McCrudden, ‘Religion, Human Rights, Equality, and the Public Sphere’ (paper to the Ecclesiastical Law Society, 13 March 2010).

23 Ibid, where Lord Walker says ‘the court is not equipped to weigh the cogency, seriousness and coherence of theological doctrines’. For a discussion of the trend of the ECtHR to define as religious only those manifestations which support a secular society, see Evans, M, ‘Freedom of religion and the ECHR: approaches, trends and tensions’ in Cane, P, Evans, C and Robinson, Z, Law and Religion in Theoretical and Historical Context (Cambridge, 2008)Google Scholar.

24 For the debate in the US on the definition of religion, see ‘Toward a constitutional definition of religion’, (1978) 91 Harv LR 1056, K Greenawalt, ‘Religion as a concept in constitutional law’ (1984) 72 California LR 753–816, R Frame, ‘Belief in a non-material reality – a proposed first amendment definition of religion’ (1992) Uni Of Illinois LR 819, J Choper, Definition of “Religion” in the First Amendment' (1982) Univ of Illinois LR 579, M.

25 However, where such beliefs are framed in more traditionally ‘religious’ terms, (eg a white supremacist religion such as ‘the World Church of the Creator’ in Peterson v Wilmur Communications 205 F Supp 2d 1014 (2002)) the protection may still be given, but again, limitations on manifestation could be allowed where the beliefs interfere with the rights of others.

41 While there is no formal separation of church and state in the UK, there is a general acceptance that the public sphere should be largely secular.

43 See C Stychin, ‘Faith in the future: sexuality, religion and the public sphere’, who raises the concern that denying any workplace ‘accommodation’ to those with religious objections to homosexuality effectively requires that those views are kept to the private sphere, and this may amount to ‘relegating those of faith to the closet from which [the LGBT community] have emerged’ (at 733).

55 See McCrudden, ‘Religion, Human Rights, Equality, and the Public Sphere’, discussing the competence of courts to rule on such issues, and the need for judges to develop a ‘cognitively internal’ point of view when considering religious issues.

56 It is notable that in Williams v Secretary of State for Education and Employment [2002] EWCA Civ 1926, some of the judges were prepared to determine what was and what was not required of Christianity, rather than considering the religious views of the particular claimants before them; See Buxton LJ at para 76, and Elias J in the first instance hearing.
