Expert evidence and forensic science in the courtroom

This free course gives an overview of the law of expert evidence, including practice and procedure, the duties and liabilities of experts, the question of how non-experts can adjudicate between the views of experts, and the increasing mathematisation of scientific evidence. The various issues are finally brought together in a case study of one of the most notorious miscarriages of justice in recent years.

This OpenLearn course is an adapted extract from the Open University course W250 Evidence law.
