Within the European socio-cultural landscape, which is increasingly attuned to animal welfare concerns and characterized by growing multiculturalism, ritual slaughter has become a subject of considerable debate due to its legal, economic, and health implications. This debate is increasingly fueled by interventions by judicial bodies that, not infrequently, have filled protection gaps in legislation on the relationship between human rights and the treatment of animals. In this review, the authors aim to describe the evolutionary path of supranational jurisprudence in the case of religious slaughter, focusing on the most recent animal welfare decision rendered by the European Court of Human Rights (ECHR) on 13 February 2024. This innovative judgement, in line with other precedents, indicates the orientation of the international and European law, which, driven by public morality, is increasingly characterized by the compression of human rights in favor of animal interests.
