4.1 Generally speaking, Australians enjoy significant religious freedom, particularly by comparison to other jurisdictions. Australians enjoy the freedom to worship and practise religion, as well as the freedom not to worship or engage in religious practices.
4.2 The common law provides limited protection for freedom of religion. The scope of religious freedom at common law is less clear than other related freedoms, such as freedom of speech.
4.3 This chapter discusses the source and rationale for freedom of religion in Australian law; how this freedom is protected from statutory encroachment; and when laws that interfere with freedom of religion may be justified.
4.4 However, in The Church of the New Faith v Commissioner for Pay-roll Tax (Vic) (the Scientology case), in defining the meaning of ‘religion’ for taxation purposes, Mason ACJ and Brennan J commented:
Freedom of religion, the paradigm freedom of conscience, is of the essence of a free society.
4.5 In Evans v New South Wales, the Federal Court described religious belief and expression as an ‘important freedom generally accepted in society’.
4.6 The freedom to engage in religious expression through observance and worship is at times intertwined with freedom of speech and expression, as well the freedom to associate.
4.7 The High Court of Australia has enumerated various definitions of ‘religion’. In the Adelaide Company of Jehovah’s Witnesses Case, Latham CJ explained that ‘it would be difficult, if not impossible, to devise a definition of religion which would satisfy the adherents of all the many and various religions which exist, or have existed, in the world’.
4.8 In the Scientology case—a case concerned with whether the Church of the New Faith qualified as a religion for the purposes of charitable tax exemptions—Mason ACJ and Brennan J expressed differing views from Wilson and Deane JJ about how religion may be defined.
4.9 Mason ACJ and Brennan J proposed the following definition of religion:
[T]he criteria of religion are twofold: first, belief in a supernatural Being, Thing or Principle; and second, the acceptance of canons of conduct in order to give effect to that belief, though canons of conduct which offend against the ordinary laws are outside the area of any immunity, privilege or right conferred on the grounds of religion. Those criteria may vary in comparative importance, and there may be a different intensity of belief or of acceptance of canons of conduct among religions or among the adherents to a religion.
4.10 Wilson and Deane JJ proposed the following definition:
One of the most important indicia of ‘a religion’ is that the particular collection of ideas and/or practices involves belief in the supernatural, that is to say, belief that reality extends beyond that which is capable of perception by the senses. If that be absent, it is unlikely that one has ‘a religion’. Another is that the ideas relate to man’s nature and place in the universe and his relation to things supernatural. A third is that the ideas are accepted by adherents as requiring or encouraging them to observe particular standards or codes of conduct or to participate in specific practices having supernatural significance. A fourth is that, however loosely knit and varying in beliefs and practices adherents may be, they constitute an identifiable group or identifiable groups. A fifth, and perhaps more controversial, indicium … is that the adherents themselves see the collection of ideas and/or practices as constituting a religion.
4.11 The exercise of religion or ‘canons of conduct’ as described by Mason ACJ and Brennan J is a source of potential conflict between freedom in the exercise of religious beliefs and the exercise by others of other rights and freedoms.
4.12 Broadly speaking, religious freedom involves positive and negative religious liberty. Positive religious liberty involves the ‘freedom to actively manifest one’s religion or beliefs in various spheres (public or private) and in myriad ways (worship, teaching and so on)’. This notion of positive rights is captured in the preamble to the Universal Declaration of Human Rights, which states that the ‘recognition of the inherent dignity of individuals’ is essential to acknowledging the autonomy of individuals to make decisions about the way they live their lives.
4.13 Negative religious freedom, on the other hand, is freedom from coercion or discrimination on the grounds of religious or non-religious belief. In the Scientology case, Mason ACJ and Brennan J commented:
[A] definition of religion … mark[s] out an area within which a person subject to the law is free to believe and to act in accordance with his belief without legal restraint.
4.14 Legal protection of religious freedom is a relatively modern phenomenon. British history is punctuated by acts of Parliament that discriminated against some groups on the basis of religion. For instance, the Act of Toleration of 1689—a reform Act of its day—allowed freedom of worship to Protestants who dissented from the Church of England (known as Nonconformists) but not to Catholics, atheists or believers of other faiths such as Judaism.
4.15 Another example is the Royal Marriages Act of 1772 which provided the conditions of a valid royal marriage including that to succeed to the throne, an heir must marry from within the Church of England.
4.16 The 17th century philosopher, John Locke, wrote about the importance of tolerating other religious beliefs:
The Toleration of those that differ from others in Matters of Religion, is so agreeable to the Gospel of Jesus Christ, and to the genuine Reason of Mankind, that it seems monstrous for Men to be so blind, as not to perceive the Necessity and Advantage of it, in so clear a light.
4.17 The concept of religious freedom recognises the existence of multiple identity groups in a pluralist democratic society. Respect for another person’s religious beliefs has been described as ‘one of the hallmarks of a civilised society’.
4.18 Thomas Jefferson, writing in his Notes on the State of Virginia, advocated for religious freedom on the basis of natural rights:
Our rulers have no authority over such natural rights, only as we have submitted to them. The rights of conscience we never submitted, we could not submit, we are answerable for them to our God. The legitimate powers of government extend to such acts only as are injurious to others. But it does me no injury for my neighbour to say there are twenty gods, or no God. It neither picks my pocket nor breaks my leg.
4.19 Recognition of freedom of religion in the common law developed significantly towards the end of the 19th century in England. Issues of religious freedom evolved in the context of wills cases, for instance in cases where a testator attempted to influence the religious tendencies of their beneficiaries by attaching conditions to a legacy, such as that the person convert to a particular religion. Generally speaking, the law will make void any condition which is in restraint of religion. Also in succession law, the equitable doctrine of undue influence has developed to extend to religious influence. In the English case of Allcard v Skinner, the Court of Appeal of England and Wales voided a gift on the basis of undue religious influence. In that case, Lindley LJ stated that:
[T]he influence of one mind over another is very subtle, and of all influences religious influence is the most dangerous and the most powerful, and to counteract it the Courts of Equity have gone very far. They have not shrunk from setting aside gifts made to persons in a position to exercise undue influence over the donors, although there has been no proof of the actual exercise of such influence; and the Courts have done this on the avowed ground of the necessity of going this length in order to protect persons from the exercise of such influence under circumstances which render it impossible.
Professor Carolyn Evans writes that ‘the common law quite possibly does not protect religious freedom’: Carolyn Evans, Legal Protection of Religious Freedom in Australia (2012) 88. To support this statement, Evans pointed to the South Australian case of Grace Bible Church v Redman where White J concluded that ‘the common law has never contained a fundamental guarantee of the inalienable right of religious freedom and expression’: Grace Bible Church v Reedman (1984) 36 SASR 376, 388.

The treatment of religious freedom in the common law of Australia developed in a different historical and legal context to that in England. This difference—which includes the fact that Australia never has any religion established by law—is outlined in the High Court’s joint judgment in PGA v The Queen (2012) 245 CLR 355,  (French CJ, Gummow, Hayne, Crennan and Kiefel JJ).

John Locke, ‘A Letter Concerning Toleration (1685)’ in David George Mullan (ed), Religious Pluralism in the West: An Anthology (Blackwell, 1998) 174. Locke spoke of toleration for Christians andnon-Christians.
‘Religious and other beliefs and convictions are part of the humanity of every individual. They are an integral part of his personality and individuality. In a civilised society individuals respect each other’s beliefs. This enables them to live in harmony’: R (Williamson) v Secretary of State for Education and Employment; ex parte Williamson  2 AC 246,  (Lord Nicholls).

There are a large number of reported cases on such facts from the late Victorian period: Peter James Hymers (ed), Halsbury’s Laws of England (Lexis Nexis Butterworths, 4th ed, 2008) vol 50, .
The common law has a range of public policy rules about the validity of conditional bequests that involve so-called restraint of religion clauses: see, eg, Rosalind Croucher and Prue Vines, Succession: Families, Property and Death (LexisNexis Butterworths, 4th ed, 2013) 550. Religious conditions attached to wills have often been held void for uncertainty: Re Winzar (1935) 55 WALR 35; Clayton v Ramsden  AC 320.
