English courts have historically been wary of deciding cases that rest on contested findings of fact about the practices and doctrines of religions. This is particularly true in defamation cases. However, the recent case of Shergill and others v Khaira and others [2014] UKSC 33 in the UK Supreme Court has narrowed the principle of non-justiciability on the grounds of subject matter. Defamation cases such as Blake v Associated Newspapers Limited [2003] EWHC 1960 (QB) have treated religious doctrine and practice as matters not justiciable per se, even if a determination is essential for the exercise of private or public law rights and obligations. The Supreme Court indicated in Khaira that it may be appropriate for courts to treat such disputes as justiciable. The common law, domestic statute and the European Convention on Human Rights protect the right to reputation, and Khaira indicates that it is time that defamation claims resting on disputes about religious doctrine and practice were entertained by the courts to a much greater extent than recent cases have allowed. However, the judgment has left open the possibility of some religious disputes still being non-justiciable.
