Sexual cases are inherently complex and sometimes controversial presenting the practitioner with a multitude of procedural and legal challenges. The increasing number of sexual cases, often historic, places significant demands upon the criminal justice system. Sexual crime is recognised as a specialist area which demands unique skills from the practitioner and handling witness testimony in these cases calls for skills and knowledge that encompass both law and science. Witness Testimony in Sexual Cases focuses on legal and scientific considerations that arise when obtaining and evaluating sexual complaint testimony. It provides comprehensive and balanced coverage of this difficult and challenging topic across the complete spectrum of involvement in the legal process. This book equips legal professionals with an understanding of current legal and scientific issues when investigating, evaluating and testing witness testimony in sexual cases. Using a didactic approach the book combines an exposition on the law and procedure with a range of specialist perspectives on cognitive processes pertaining to vulnerable and non-vulnerable witnesses. The book identifies psychiatric and psychological factors that may enhance or impair the quality of witness testimony for instance where a witness suffers from mental health problems or where long-term memory recall is involved. The book provides practitioners with an understanding of factors which tend to undermine the reliability of witness testimony, but also focuses on those factors which may enhance witness quality. Witness Testimony in Sexual Cases draws together learning not readily available and encourages an integral and rigorous approach to the analysis of witness testimony in the special context of sexual cases.

Testimonial evidence remains the greatest source of information available to those who try cases in court.Witness Testimony: Psychological, Investigative, and Evidential Perspectives provides a comprehensive and easily accessible guide to the decision-making and actions of the complete spectrum of practitioner involvement in the criminal justice process, right from initial investigation through to court-room proceedings. It builds on the content and structure of its ground-breaking predecessor Analysing Witness Testimony: A Guide for Legal Practitioners and Other Professionals (Blackstone Press, March 1999), and consists of 25 chapters written by an expert author team of practitioner and academic lawyers, forensic psychiatrists, and psychologists. The team is led by criminal evidence specialist barristers Anthony Heaton-Armstrong and David Wolchover, chartered forensic psychologist Dr Eric Shepherd, and Professor of Forensic Psychology, Gisli Gudjonnson. The book is logically divided into three sections, looking in turn at each of the three inter-related perspectives upon a witness' account; psychological, investigative, and evidential. Section One explains and examines psychological issues, including; witness memory; the effect of learning disabilities; false allegations of sexual assault; and the effect of physical factors such as head injuries and drugs. Section Two covers the crucial investigative issues and concerns in respect of false allegations; the impact of investigative and questioning style upon children and vulnerable persons; memory performace of witnesses; and linguistic interpretations. Section Three explores evidential issues such as; visual identification procedures; the status of witness demeanour; the reliability of oral evidence; the relevance of information technology to presentation of evidence; disclosure; the use of expert evidence; and judicial training. The book will therefore be indispensable to all those involved in the resolution of contentious or disputed evidence, including; members of the judiciary and legal practitioners; crime investigators; and forensic psychologists and psychiatrists.
