Disclosure issues affect every stage of the criminal investigation and subsequent proceedings yet this book is the only modern, comprehensive and in-depth volume on the subject. It provides the practitioner with a detailed analysis from a practical perspective by following chronologically the progress of a case from the outset of an investigation until its conclusion, addressing the obligations and responsibilities of each of the parties as they arise. The book focuses primarily on disclosure of the prosecutor's unused material, but it also covers the timing and content of disclosure by the prosecution of its case, and the obligations on the defence. Dedicated chapters on more specialist topics such as expert evidence, public interest immunity, and unused evidence are also included. The text analyses all the relevant law and procedure, to place practitioners in the best position to argue their case. It contains carefully selected appendices - comprising relevant parts of Criminal Procedure and Investigations Act 1996 as amended by the CJA 2003; CJA 2003; extracts from the Criminal Procedure Rules 2005; the CPIA Code of Practice; the new Attorney General's Guidelines on Disclosure; the Protocol for the Management of Heavy Fraud and Other Complex Criminal Cases; and extracts from the new CPS/ACPO Disclosure Manual.
