The scale and variety of acts of religious intolerance evident in so many countries today are of enormous contemporary concern. This 2005 study attempts a thorough and systematic treatment of both Universal and European practice. The standards applicable to freedom of religion are subjected to a detailed critique, and their development and implementation within the UN is distinguished from that within Strasbourg, in order to discern trends and obstacles to their advancement and to highlight the rationale for any apparent departures between the two systems. This dual focus also demonstrates the acute need for the European Court to heed the warnings from various patterns of violation throughout the world illustrated by the Human Rights Committee and the Special Rapporteur on freedom of religion or belief.
