The panel explores new challenges for sustainable accountability and new approaches to assessing it in the EU multilevel system. Several institutions have been established over the past decades that are supposed to contribute to EU accountability, e.g. the European Court of Auditors and the European Ombudsman. In parallel, developments such as the reactions to the financial crisis since 2008 have led to new challenges and accountability arrangements. Control of the EU budget and administration has become the focus of increased scholarly attention. This panel brings together a number of scholars that represent a new research perspective on the changing financial accountability in the EU. The panel aims to contribute to a further understanding of the dynamics of financial accountability in the European Union. The panel is organised in cooperation with the research network on Financial Accountability in the EU (EUFINACCO, https://eufinacco.wordpress.com/).
