This chapter, which focuses on opinion evidence in criminal and civil cases in the UK, explains the rule on the admissibility of opinion evidence, largely expert opinion. The notice and disclosure rules in criminal cases under the Criminal Procedure Rules (CPR) are outlined. The criteria for the admissibility of expert evidence, the responsibilities of expert witnesses, and the approach of the courts to new areas of expertise are examined in detail. It also considers the presentation of expert evidence, including the use of court-appointed experts, in civil cases under the CPR, and, finally, examines the ultimate issue rule, which has been abolished by s33(1) of the Civil Evidence Act (CEA) 1972.
