This volume brings together seven essays contributed by political science, law, and religion scholars from Europe, Australia, Israel, and the US, who consider law in the context of religion and social change. In the first section, they examine the interaction between law and religion in terms of religious schools and equality in education in various countries; the Obergefell v. Hodges decision and religious free exercise in the era of Donald Trump; male circumcision, Jewish difference, and German law; and the Sharia debates, religious accommodation, and informal institutional norms in Australia, Canada, and the UK. The second section focuses on how the law enhances and inhibits projects of social change, with discussion of the role of legal intermediaries, the political risks of litigation in American policymaking, and the use of law and legal institutions by the social movement seeking to end Australia's policy of mandatory detention for refugees and asylum seekers.
