Which are the borders of the secret, for a jurisdictional body such as a Constitutional Court? Which areas of the institution must be covered by the secret? Recently, the Italian constitutional Court has become an interesting case of study. On the one hand, the practice of press releases and initiatives such as visits to prisons and schools aim to bring the body closer to public opinion and to enhance that plan of legitimacy linked to its activity. On the other hand, the Court itself sometimes does not seem to guarantee adequate transparency in its workings, which would be capable to involve public opinion in the institutional circuit. Some interna corporis are not known (for instance, the Rules for the services and the staff), although they are essential to better understand Court’s institutional life. From this perspective, the analysis will deal with the ubi consistam of secrecy for the Court.
