"In this report, the authors examine and compare state implementation and enforcement of criminal laws prohibiting blasphemy (“blasphemy laws”) worldwide over the five-year period between January 2014 and December 2018. The criminal cases this study analyzes represent states’ enforcement of laws that sanction the expression of opinions or actions deemed “blasphemous,” or counter to majority views or religious belief systems. Many such laws impose serious penalties, including prison, forced labor, or death, upon those convicted. Countries throughout the world have and continue to enforce criminal blasphemy laws, often justifying them as necessary to promote intergroup religious harmony. In some states, however, civilians enforce blasphemy prohibitions extrajudicially, committing acts of violence in the name of protecting God, religion, and “the sacred.” Analyzing the ways in which states and private, non-state actors enforce these laws may assist the public policy community in developing clear, tailored recommendations for areas of criminal legal reform, especially in states with vague laws, harsh penalties, and high levels of enforcement. An analysis of criminal blasphemy cases reported in the news and adjudicated in courts identifies the contexts in which blasphemy laws may increase the risk of human rights abuses, through state acts or omissions, indicating the places and ways in which targeted law reform could lower that risk."
