This book considers how the law should manage conflicts between the right of religious freedom and that of non-discrimination on the grounds of sexual orientation. Starting from the basis that both these rights are valuable and worthy of protection, but that such disputes are often characterised by animosity, it contends that a proportionality analysis provides the best method for resolving these conflicts. The work takes a comparative approach, examining the law in England and Wales, Canada and the USA. The book will be an invaluable resource for students and researchers in the areas of Public Law, Human Rights Law, Law and Religion, Discrimination Law, and Comparative Law.
