Disclosure issues affect every stage of the criminal investigation and subsequent proceedings. It has been the subject of numerous critical reviews for more than a decade, but no single text has sought to draw the product of those reviews together in one place. Disclosure in Criminal Proceedings is the only practitioner text on the market to explore in detail this vital aspect of criminal procedure. Revised guidelines for managing disclosure in criminal cases were promulgated by the Attorney General in 2020, and have been updated since, but disclosure failures continue to occur. When miscarriages of justice happen, often it is because the approach to disclosure taken by the prosecution, the defence, and the court was flawed. In its second edition, written by a team of authors drawn from the ranks of Treasury Counsel, Disclosure in Criminal Proceedings provides a step-by-step analysis of how the rules of disclosure operate throughout the life of a criminal case, from the initial investigation through to any trial, appeal, and beyond. Appointed by the Attorney General to prosecute the most serious cases in the country, the authors approach the topic with decades of experience of handling some of the most complex and seemingly intractable disclosure problems that can arise in the criminal courts. With first-hand experience informing every page of this new edition, Disclosure in Criminal Proceedings is an indispensable guide to an area of criminal procedure that arises in every single criminal prosecution.
