Amid several high-profile ethical scandals, the EU has been discussing since the early 2000s the establishment of a dedicated EU ethics authority capable of regaining trust in the operation of its institutions. This chapter provides a first, preliminary assessment of the newly adopted EU Interinstitutional Body for Ethical Standards by examining whether and how it can contribute to strengthening the existing and largely fragmented EU public integrity system. After tracing its genesis and evolution, it assesses whether the newly adopted EU ethical body may address and overcome the structural limitations of the existing EU public integrity system and how. It concludes that, despite its limited authority—both in terms of investigative and sanctioning powers, this first dedicated Interinstitutional Body for Ethical Standards carries the potential to mark a qualitative difference in the development of the EU public integrity system as we know it. Through a combination of its standard-setting, advisory and awareness-raising functions, the Body may profoundly alter both the ethical standards and their enforcement on the participating institutions’ members and beyond.
