This book offers a complete and practical vision on the CouncilFramework Decision 2008/947/JHA of 27 November 2008 on the application of the principle of mutual recognition to judgments and probationdecisions with a view to the supervision of probation measures andalternative sanctions and Council Framework Decision 2009/829/JHA of23 October 2009 on the application, between Member States of theEuropean Union, of the principle of mutual recognition to decisions on supervision measures as an alternative to provisional detention.Having been progressively incorporated into the different legalsystems of the EU countries, those instruments, known respectively asthe European Probation Order (EPO) and the European Supervision Order(ESO) are still very underused today. The promotion of the use ofthese legal instruments is therefore presented as urgent andnecessary, in order to ensure the social reintegration of the users of the criminal justice systems that today, without borders between theEU states, make up a single area of security and justice. Firstly,this manual it includes an analysis of their content and state ofimplementation. Secondly, an analysis is carried out of both thealternative measures to pre-trial detention and the penalties andcommunity measures alternative to the prison sentence in force in thecountries involved in the production of this manual: Spain, Romania,Germany and Latvia. All the obstacles that have been detected in theimplementation of the aforementioned Framework Decisions after twoyears of quantitative and qualitative research are detailed andpractical solutions are projected, as well as existing resources,which will allow these obstacles to be solved, thus promoting the useof both legal instruments by lawyers, judges, prosecutors, officialsrelated to the administration of justice, as well as by the users ofthe criminal justice system. The most interesting jurisprudence of the Court of Justice of the European Union in relation to these Framework Decisions, as well as some significant real cases, are finally addedto make this manual even more practical and useful for the eventualreaders of this work.
