"We analysed a special session of the Swiss national council on "Dying forests" which was called for so that swift action to stop the forest deterioration could be taken. According to our theoretical approach we collected data at different time points (calling for the session, during the session, several days after the session) of several actors (parliament, political party, members of national council) and from various perspectives (politicians, media, passers by). The following data will be presented: from questioning of politicians and passersby prior to the session, their comparison, results of votes in the session and their comparison with the questioning prior the session."
