The right to freedom of religion, enshrined in the European Convention on Human Rights has been frequently tested, both in UK courts and in the European Court of Human Rights, where successive decisions over a number of years led to the establishment of several well-known principles. However, in recent years religious extremism has brought into focus a tension between the right of freedom of religious expression and the well-being of individuals (not least children) and society. The Strasbourg court requires neutrality on the part of the state and its courts. However, unlike the European Court of Human Rights, the domestic courts have had to face situations where religious observance can be seen to be causing serious harm and where interference in religious freedom and family life has been shown to be justified.
