The aim of this EU FP5 project was to analyse the relevance of public accountability procedures as tools for achieving publicly legitimate and socially sustainable policies and decisions. This was done through empirical research and comparative analysis, in relation to seven national, and three socio-technological contexts. The background of this project was the lack of existing in-depth knowledge of the role of public accountability in contemporary, socially complex European policy- and decision-making and public debates. The project thus aimed to specially contribute to the discussion of the structural changes arising from the ongoing European integration and enlargement process. The project resulted in country-related profiles, issue-specific case studies, and an integrating comparative view of public accountability procedures in a European context.The results were disseminated through national and trans-national seminars.
