Disclosure remains the most important part of trial preparation and can often make the difference between conviction and acquittal. The process can only work and produce fair results if all parties to the process are aware of their duties.

The second edition of Criminal Disclosure Referencer (first edition: The Disclosure Referencer) provides practitioners with a practical, user-friendly guide to the law and guidance relating to the disclosure of unused material. The text follows the disclosure process chronologically from the commencement of the investigation to the conclusion of the case drawing together all the relevant legislation, codes, guidelines, rules, protocols and case law in a comprehensive manner, thereby enabling the reader to see quickly and effectively the duties and obligations of the main participants.

Since the last edition of this work, the criminal justice landscape has changed fundamentally. The number of pre-trial hearings have been drastically reduced and replaced with a single 'Plea and Trial Preparation Hearing'. The principles of 'Better Case Management' have been introduced, requiring advocates to take more responsibility in relation to disclosure. In the vast majority of Crown Court cases evidence and disclosure are now provided digitally. All of these changes require parties to the criminal justice system to be fully up to date with their obligations in relation to disclosure.

The second edition is updated to take account of numerous developments in legislation, case law and procedure including:

Attorney General's Guidelines on Disclosure (updated October 2013)
Judicial Protocol on the Disclosure of Unused Material in Criminal Cases (updated December 2013)
