What do international and EU law require from the national asylum judge with regard to the intensity of judicial scrutiny to be applied and evidentiary issues? To answer that question, an analysis is made of the provisions on national judicial proceedings contained in the Refugee Convention (RC), the International Covenant on Civil and Political Rights (ICCPR), the UN Convention against Torture (CAT), the European Convention on Human Rights (ECHR), and the EU Charter of Fundamental Rights. In addition, the assessment as performed by the UN Human Rights Committee, the UN Committee against Torture and the European Court of Human Rights in cases concerning the expulsion of asylum seekers is analysed.
