Born at
Misilmeri, Chinnici graduated in law at the
University of Palermo in 1947 and started working as a magistrate in 1952 in
Trapani. In 1966 he moved to the prosecutors office in Palermo. In November 1979, he became head of the Examining Office at the Palermo Court, following the murder of his predecessor,
Cesare Terranova, by
the Mafia. At the time the prosecution was separated in an examining phase (the so-called instruction phase) and a prosecuting phase. Chinnici created the
Antimafia Pool, a group of investigating magistrates who closely worked together sharing information to diffuse responsibility and to prevent one person from becoming the sole institutional memory and solitary target. The famous Antimafia magistrates
Giovanni Falcone and
Paolo Borsellino were part of the
Antimafia Pool as well as and . The Antimafia pool laid the groundwork for the
Maxi Trial against the Sicilian Mafia in 1986. He was instrumental in reviving investigations into the Mafia and understood the need to bridge the gap between the judiciary and the rest of Sicilian society to create a counterculture against the Mafia and break down
omertà, the law of silence that kept the Mafia alive. He frequently spoke out against the Mafia in public appearances and schools at a time when judges had avoided the word for many years. ==Death==
