Berlusconi's attempt to change the consitution through a simple parliamentary majority was shot down by the obligatory referendum in 2006 while a constitutional change proposed by the Olive coalition in 2001 passed by a large majority of citizens. The former was an improvised sectarian initiative designed mainly to please the Lega Nord while the latter was clearly in the interest of the nation. The Italian constitution has some provisional or transitional sections that were to be changed over time. Beyond the 2001 modifications, those reforms have yet to be undertaken.

Attempts were undertaken in the so-called Bicameral Roundtable in the late 90's. It was a political trap exploited by Berlusconi to give himself an aura of statesmanship. Once he had what he wanted in terms of positive public exposure and with elections around the corner, he simply walked out without an explanation. All the better given that the Left had made ridiculous consessions. And risk to continue to do so if ever in power again.

There's nothing worse than a party that stoops to actuating the opposition's program.
