The influence of local news aired by the main media of mass communica-tion, in the public agenda and in the public opinion, takes the press to be consid-ered for important segments of society, the Fourth Estate of the Republic - and is the basis for the appearance, in the 1970s, of an important academic study, which the Americans Maxwell McCombs and Donald Shaw, the authors, called the theory of agenda. With mandatory connection to the research on this subject are the exercise of freedom of expression by the press - from the perspective of theo-ries of journalism and journalistic community - and how society in general way and legal practitioners in a particular-way understand freedom of the press and the growing conflict of this freedom with the constitutional rights of personality, in-creasingly evident in a contemporary globalized world, in which economic inter-ests of large media companies of mass communication originate instantaneous and often politicized informations. With the premise that the media of mass communi-cation produce social representations of the reality, it is still relevant the relations of power-knowledge speeches of the media and the influence of the news on the pace of court proceedings and decisions of magistrates, as it can be seen on the journalistic coverage, especially in O Globo, regarding to the trial of Criminal Case 470, by the Supreme Court between August 2012 and March 2014.
