Migration is a global phenomenon that is continuously growing due to events related, among many, to war, religious intolerance, climate change and economic hardship. Immigrant-receiving countries are confronted with a more and more culturally, linguistically and religiously diverse society. The right to freedom of religion, which is granted as a human right in various treaties on the international level but also as a fundamental right in many constitutions is of particular relevance in this regard. In order to identify the state of and differences in human rights standards with regard to new minorities’ right to freedom of religion, going beyond specific sets of conflicting decisions, it is necessary to examine the current practice in detail. This has not yet been done in existing literature that rather focuses on criticising or comparing specific sets of contradicting decisions or decisions with regard to a specific religious practice.
