This guidebook presents a set of standards for disclosure and publication of crime-related information. The standards are categorised by the two main types of stakeholders: authorities and media. It contains a cutting-edge compendium of recommendations based on the existing body of literature, national and international legislation, legal principles, case law and good practices. It also reflects the findings of the research conducted under the ARISA 2 project, which shed light on the relevant national legislation in four Member States; identified common malpractices through analysis of case studies, and made a state-of-art review on the applicable ethical and legal norms. In addition, the Guidebook attempts to provide guidance on issues that are not sufficiently and thoroughly covered by the EU and national criminal justice, media, and data protection rules and codes of ethics.
