Evidence is at the heart of adjudication, and adjudication at the heart of the international protection of human rights. Yet evidence in international human rights adjudication has rarely been studied. DISSECT is a ground-breaking research programme funded by the ERC through an advanced grant, which captures and compares the evidentiary regimes which have been developed by the world’s three regional human rights courts and UN human rights quasi-judicial bodies. Examining how judicial protocols and social realities impact the production and assessment of evidence, it demonstrates through concrete case studies how the finding or rejection of the factual aspects underlying complaints of human rights violations is not just a question of proof and truth but also one of ethics and power.
