This chapter discusses international investigations in Ireland. It notes that Ireland is generally perceived as having a low level of corruption and as being a secure place to do business. However, Ireland has been criticized for its lack of enforcement in areas like corporate governance and white-collar crime. In response, the Irish government published measures in 2017 to strengthen its response to corporate misconduct. Several of these measures have since been introduced, such as a new corruption offenses act. The chapter also outlines recommendations from a 2018 law reform report, including establishing a corporate crime agency and introducing deferred prosecution agreements. It concludes by noting the increased regulatory oversight and enforcement in Ireland in recent years.
