Public opinion concerning judiciary and law aims directly to the social conflicts，concerning the vital interests of the public because of its special attributes. Through the high-temperature fermentation on the Internet，public opinion on judiciary and law spread fast，which puts forward a severe challenge to the relevant organizations and tests their response capacities. The ability to deal with such type of public opinion directly affects the social public order and stability，and to some extent，reflects the progress of legal-society formation in China. The Public Opinion Research Laboratory of Shanghai Jiao Tong University selected 249 hot public events involving judiciary and law in 2012-2014 as the sample based on the heat index of public opinion. Through the comparison of the longitudinal data for the three years and the analysis of the typical cases in the year of 2014，the investigation explored the causes and solutions to the public events involving judiciary and law，and provided suggestions on the coping strategies. <<
