please the Lega Nord. The 2002 Bossi-Fini Act represented a restrictive approach to immigration, while the 2006 Fini-Giovanardi Act strengthened the prohibitionary approach to drug policy. A point-system driver's licence was introduced in 2003, and compulsory conscription was replaced by a professional army since 2005. A constitutional reform including federalization and strengthened executive powers, passed in the Parliament, was rejected by a confirmation referendum in 2006. Berlusconi's term was widely criticised for the approval of ad personam (personal)laws (usually named from the rapporteur minister or MP), especially in the field of justice, such as: the Frattini Act on conflict of interest; the 2002 Cirami Act on the recusation of judges by the accused; the 2003 Schifani Act, shielding the five highest state posts from criminal proceedings (declared unconstitutional in 2004); the 2005 ex-Cirielli Act, about statute of limitations, especially applicable in the case of Cesare Previti, Berlusconi's lawyer; the 2006 Pecorella Act, making it impossible for the public prosecutors to appeal a sentence of acquittal (partially declared unconstitutional in 2006); the de-criminalisation of false accounting; the Gasparri Act on the radio & TV market, making it easier for Mediaset to escape roof limits of advertisement collection, and considered not in compliance with EU Law by the EU Commission; Internally, Berlusconi set up the Mitrokhin Commission, directed by senator Paolo Guzzanti (Forza Italia), to investigate on alleged KGB ties by left-wing (then-opposition) politicians.

A party presents its own closed list and it can join other parties in alliances. The coalition which receives a plurality automatically wins at least 26 seats.
