This seminar explores the production and politics of legal evidence, scientific proof, and uncertainty. It unpacks the ways in which technical-scientific knowledge production processes are mobilized within the legal field, and enable certain legal and political outcomes, while making others impossible. Drawing on the fields of political and legal anthropology, science and technology studies and critical human geography, the seminar brings foundational texts investigating epistemological and ontological conditions of evidence, certainty, and uncertainty together with the recent ethnographies of controversies in the fields of law and science. The seminar will examine various cases that include, but are not limited to, injury claims, environmental contaminations, systematic human rights violations, and political asylum cases.
