As a road haulier, Meloni begins his political career as a councilor of the Terralba Social Movement in Terralba. He later joined the Sardo d'Azione and was among the promoters of the motion that on December 6, 1981 at the XXth congress of the party, resolved to amend art. 1 of the Statute, inserting the word "independence" instead of "stateless autonomy" without any reference to the Italian state
In December 1981, he was arrested after the explosion was found in his home in Terralba, accusing him of having committed an attack on the Cagliari headquarters in Tirrenia and being in charge of a separatist plot to make Sardinia independent of the state Italian. After the arrest, Melons begins a series of hunger strikes to protest against what he thinks is an outrageous political persecution, and he founded the Partidu sardu pro s'indipendentzia (PARIS) with which he participated in the regional elections . In October 1984 he was sentenced to nine years' imprisonment with the accusation of political conspiracy and subversive association against integrity, independence and unity of the state.Melons is the only Italian ever condemned for this offense. Following the sentence, the right to vote is revoked and the perpetual ban on public offices is imposed.
Give up honoring the story again in 2008 when he declares independence of Maldra's Island. He died after 66 days of hunger strike in Uta prison (Cagliari) where he was recruited for crimes of a fiscal nature.
