intended to mirror the legislative provisions for public-office holders in 1990: no one should stand for election who had been committed for trial, was a fugitive from the law, was serving a criminal sentence, was subject to preventive measures or was convicted, even though not definitively, for crimes of corruption, Mafia association and a range of others. A week before the election the Commission reported that on the basis of information received from two-thirds of the prefectures in the country, 33 candidates standing in the forthcoming elections were ‘non presentable’ according to the code of self-regulation. Fourth Commission (1992-1994) The fourth Commission was installed on June 8, 1992, after the murder of judge Giovanni Falcone on May 23 and was modified after the killing of his colleague Paolo Borsellino on July 19.

Important pentiti like Tommaso Buscetta, Antonio Calderone, Leonardo Messina and Gaspare Mutolo gave testimonies. It found that Salvo Lima, a former Christian Democrat mayor of Palermo who was murdered in March 1992, had been linked to the Mafia and that former Prime Minister Giulio Andreotti had been Lima's "political contact" in Rome. On November 16, 1992 Tommaso Buscetta testified before the Antimafia Commission. "Salvo Lima was, in fact, the politician to whom Cosa Nostra turned most often to resolve problems for the organisation whose solution lay in Rome," Buscetta said. Other collaborating witnesses confirmed that Lima had been specifically ordered to "fix" the appeal of the Maxi Trial with Italy's Supreme Court and had
