A "superstar" lawyer: this is how PietroMastino has been defined, a noble example of a forensic tradition from Nuoro animated by personalities with high ethical and moral values as well as supported by a deep juridical and cultural expertise (starting from the jurisprudent-vateSebastianoSatta). Son of a respected lawyer who has been – for several times– the mayor of Nuoro, he would completely follow his father's footsteps, distinguishing his person for his committed anti-fascist political militancy too, whose most resounding event was in 1932 during a demonstration carried out with his colleagues Luigi Oggiano and Gonario Pinna. At the fall of the regime, he was among the founding fathers, but his national engagement between the Parliament and the Senate of the Republic would have never distracted his attention from the beloved land and hometown, on which –as a mayor between 1956 and 1962– he would have operated for the purpose of an overall improvement. The grief for his death gathered his colleagues and political comrades in the awareness of the loss – ordinary citizens too – that shared all together the heartfelt "Addio!" pronounced in his memory by his friend and comrade Luigi Oggiano.
