This Irish EPPO/OLAF volume focuses on the powers of the Irish authorities, including the Criminal Assets Bureau, An Garda Síochána, and prosecutors, in investigating EU fraud offences. It also discusses the possible consequences of Ireland’s hypothetical accession to the EPPO. Moreover, it explores the role of OLAF and the powers of its national partners, such as the Irish Tax and Customs Office in investigative missions, citing tobacco smuggling and oil or fuel laundering as examples. Noelle Kenny and Claire O’Regan have acted as the publication’s national experts. This volume includes footnotes that reproduce the original Irish legislation. Easily navigable with the help of visual symbols, it is designed as a quick reference tool for academics, students, practitioners and other interested readers.
