The right to freedom of religion or belief, as enshrined in international human rights documents, is unique in its formulation in that it provides protection for the enjoyment of the rights "in community with others". This book explores the notion of the collective dimension of freedom of religion or belief with a view to advance the protection of this right. The book considers Turkey which provides a useful test case where both the domestic legislation can be assessed against international standards, while at the same time lessons can be drawn for the improvement of the standard of international review of the protection of the collective dimension of freedom of religion or belief. The book asks two main questions: what is the scope and nature of protection afforded to the collective dimension of freedom of religion or belief in international law, and, secondly, how does the protection of the collective dimension of freedom of religion or belief in Turkey compare and contrast to international standards? In doing so it seeks to identify how the standard of international review of the collective dimension of freedom of religion can be improved.
