law to a full first past the post system. The Italian radical party and the right wing National Alliance were also collecting signatures for the same exact petition on electoral reform at the same time as Di Pietro's party, showing that often parties from vastly different political beliefs will agree on the same themes that they feel should be subject to referendums. However, often political parties who are even in the same coalition will have very diverse opinions with regard to referendums. A notorious example of this came in 1999 when the right-wing National Alliance, led by Gianfranco Fini, was collecting signatures for two referendums to abolish political party state financing and a change in electoral law to a full first past the post system, while the Italian Radicals and Di Pietro's Italy of Values were also collecting signatures at the same time. Despite spending an enormous amount of manpower and party funds across all of Italy, his main partner in the House of Freedoms coalition, Forza Italia, led by former and soon to be Prime Minister Silvio Berlusconi, offered no political or financial support. When voting for the referendums took place in 2000, Berlusconi almost abstained and said the vote was "mostly pointless" as he would take care of all reforms when he would return to power. When the House of Liberties coalition returned to power in 2001, Berlusconi did not abolish political party financing and even reintroduced proportional representation into the electoral law. Critics pointed out that these new measures, approved even with the parliamentary votes of Alleanza Nazionale itself, were proof that Fini and his party had made a complete volte-face and abandoned some of their core political reforms in order to stay in power. It was also seen as proof that Fini's influence in the coalition was not as strong as many were led to believe. Constitutional referendums Requirements A constitutional referendum can be requested by 500,000 voters, five regional councils, or one-fifth of the members of a house of parliament when Parliament adopts a constitutional law (including a law to amend the constitution) with an absolute majority in the second vote, but without meeting a two-thirds qualified majority in each house. The referendum must be requested within three months from the publication of the bill in the Official Gazette. Unlike a popular referendum, a constitutional referendum is confirmatory. This means a "Yes" vote is a
