The Eurozone crisis, the rise of Eurosceptic parties in European and national elections and the success and importance of new ICTs, according to many scholars, have put parliaments to the margin of decision-making, given the high level of technical expertise that those issues requests. Is it possible to reconcile democratic accountability and legal, political and economic expertise in the EU and in its Member States? The Jean Monnet Module PATEU aims to offer a different reading, compared to the conventional one, regarding the role played by parliamentary institutions in those fields at national and supranational level. Although the three challenges have triggered a process of institutional adaptation by the Parliaments, these institutions still play a very important role in policy-making. PATEU will be placed in the framework of the existing Summer School on “Parliamentary Democracy in Europe”, at LUISS School of Government, and will be developed as a two-week course (11 days on the whole) for three years (to start with), devoting each edition to a subject linked to parliamentary accountability and technical expertise: (2017) Parliaments and budgetary powers; (2018), Parliaments and new ICTs; (2019) Parliaments and elections. PATEU, as a multidisciplinary programme addressed to postgraduate and PhD students and young professionals, will be based on a combination of theoretical and practical activities through lectures, training courses, guest professional seminars, study visits and other activities. The impact of PATEU will not only consist in improving and deepening the knowledge of the participants in EU studies, but also in promoting the research and teaching of the young academics who are part of the teaching staff as well as of the Academic Coordinator and Module Leader and the dissemination of the research and teaching outcomes mainly though the PATEU’s website and the LUISS website in general.
