Amid growing public concern about the negative effect cross-examination has on vulnerable witnesses, this book examines the effect of recent reforms to the practice across the different jurisdictions of the UK and Ireland. Drawing on observations and transcripts of trials and interviews with judges, advocates and intermediaries, the book provides an evaluation of cross-examination in trials involving vulnerable witnesses and the extent to which reforms are producing meaningful change. The book's analysis sheds new light on the significance of cross-examination in criminal trials and provides evidence-based solutions for further changes to enable vulnerable witnesses to give their best evidence to the court.
