sentences:  The Commission had to work in one of Italy’s most critical moment when the country’s democracy was challenged by criminal subversion by the Mafia and the Mani pulite investigation that unravelled Tangentopoli (Italian for "bribeville"), the corruption-based political system that dominated Italy.Despite the political sensitive nature of the Commission’s work, Violante’s greatest achievement was that the most important reports were backed by all major parties instead, as in the past, of producing majority (government) and minority (opposition) reports on the same theme.Important pentiti like Tommaso Buscetta, Antonio Calderone, Leonardo Messina and Gaspare Mutolo gave testimonies.
