 
A three-part abrogative referendum was held in Italy on 3 June 1990, with two questions about hunting and one on health. Turnout was low, with a 43% of the electors participating to the referendum. For the first time since the adoption of the Constitution in 1948, a referendum did not obtain the quorum, and all three were consequently declared null and void.
Hunting referendums.
The hunting abrogative referendums concerned two issues:
These referendums were the first ones ever proposed by the Italian Greens. Although both referendums had a "yes" victory with more than 90% of votes, they were annulled according to the Italian Constitution which wants a 50% of turnout for a valid referendum.
Use of pesticides referendum.
The third abrogative referendum concerned the right of the Italian Ministry of Health to establish limits for pesticides. The Greens said that these limits was decided upon reasons of political friendship rather than upon scientific bases. Even this referendum, despite its 90% of "yes" votes, was annulled for its low turnout.
