Referendum 'Stuttgart 21'
During the last months, the public conflict about the infrastructure project "Stuttgart 21" has raised fundamental questions concerning the modalities of political participation and the legitimacy of political decisions. It became clear that the participation processes that were part of the planning and approval stage were not enough to ensure the acceptance of the project. Also the ad hoc mediation lead by Heiner Geißler did not result in wide-spread acceptance: The public protest went on hardly changed. After the state election in March 2011, the coalition partners agreed to hold a referendum to solve the issue. The referendum was accompanied by a series of surveys. In continuation of the project "Election Study Baden-Württemberg 2011", the respondents of the previous study were surveyed again before and after the referendum, again implementing an online rolling panel design. As in the run-up to the state election, the instrument allows to trace and analyse processes of opinion formation and decision making in great detail. With regard to the referendum and the issue of "Stuttgart21", special attention was given to questions of political legitimacy. The online survey was accompanied by two telephone surveys. At the moment the surveyed data is being prepared for further analysis.
