In this book, legal, biomedical, psychosocial, and social science scholars and practitioners offer the first comparative account of the increasing dependence on expertise in the asylum and refugee status determination process. This volume presents a comprehensive study of the relevance of experts, as mediators of culture, who are called upon to corroborate, substantiate credibility, and serve as translators in the face of confusing legal standards that require proof of new forms and reasons for persecution around the globe. The authors provide insights into the evidentiary burdens on asylum seekers and the expanding role of expertise in the forms of country-conditions reports, biomedical and psychiatric evaluations, and the emerging field of forensic linguistic analysis in response to emerging forms of persecution, such as gender-based or sexuality-based persecution.
