Other countermeasures provided by the government include a ban on rockets, smoke-producers and firecrackers at sports events, the prohibition of night-matches for the entire month of February 2007, a ban on the block sale of tickets to away supporters, and the so-called "preventive Daspo" (where Daspo stands for "Prohibition to Participate to Sports Events"), which since 1992 allows the police force to precautionarily ban suspected hooligans from attending football matches. Clubs will also be forbidden to make financial or working relationships with the fan associations. The Amato decree which included all such measures was finally ratified by the Senate on 4 April, only five days short of its expiration (in Italy, a governmental decree must be ratified by both the chambers of the Parliament in sixty days).
