The JCOERE (Judicial Cooperation Supporting Economic Recovery in Europe Project) (No 800807) funded by the European Commission DG Justice Programme (2014-2020) commenced in 2018 led by a team at University College Cork, Ireland under Principal Investigator, Professor Irene Lynch Fannon in partnership with Universit√ degli Studi di Firenze, Universitatea Titu Maiorescu in Bucharest, and INSOL Europe. The JCOERE Project focussed on cooperation obligations imposed by the European Insolvency Regulation (Recast) on domestic courts across the European Union. The JCOERE hypothesis was that the complexity of preventive restructuring processes mandated as part of recent policy initiatives of the EU rendered such cooperation obligations even more challenging. Many obstacles identified by the JCOERE Project were equally applicable to a broader range of initiatives concerning judicial cooperation in the European Union. This first chapter presents the JCOERE Project and research methodology as well as setting out the extended focus of the monograph, which develops the JCOERE findings and broadens the application of the doctrinal case study to consider concepts such as harmonisation, procedural coordination, judicial cooperation and the implications for further integration in the EU.
