Inquisitorial and Adversarial Expert Examinations in the Case Law of the European Court of Human Rights

Abstract

The administration of criminal justice may require specific scientific or technical knowledge, for which experts are asked to provide advice to criminal courts. This article addresses the approach by the European Court of Human Rights to the input of expert evidence in domestic criminal proceedings. Two models, an inquisitorial model and an adversarial model of criminal justice, are identified and employed as a framework to analyse the case law. The article further elaborates on the use of these models, the sets of procedural requirements linked to both models, and the interference between them, providing insights capable of improving the gathering and use of technical and scientific information.
