This article examines the role of cultural expertise in asylum judicial decisions in the UK by focusing on witchcraft-based persecution. The case study highlights multiple challenges to decision-making created by religious and cultural diversity, and the ensuing problems of assessing unfamiliar facts and beliefs against the often lack of corroborating evidence. Drawing on legal sources and a small number of anthropological studies, as well as analyses of judicial decisions, the article discusses how the unique characteristics of witchcraft cases, with their unfamiliar paradigms, are illustrative of the need to analyse and understand asylum claims within their broad cultural, historical, economic, and political contexts. The article exposes how cultural expertise assists judges in appreciating specific contexts and curbing their Eurocentric understanding of culture and religion, and shapes the final outcome of cases.
