The last half century has been characterized by a growth in the regulation of clinical research nationally and internationally. Each area of research on human subjects has been the subject of a vast academic literature and extensive public policy debate, from issues of informed consent to that of regulatory structures. Professor Bernard Dickens has provided an outstanding contribution to this debate internationally through his many innovative and incisive papers in this area. This paper provides an English lawyer’s perspective upon the increasing regulation of clinical research practices and asks – does regulation equate with effective rights protection? From Nuremberg onwards, there has been concern to ensure that research practices are ethical and in accordance with legal principles. So, for example, there have been statements such as the Declaration of Helsinki, which was initially produced in 1964. In the European context in particular, notably influential statements have been the European Convention on Human Rights, which has been followed by the Council of Europe Convention on Human Rights and Biomedicine and, more recently, a Draft Additional Protocol on medical research.
