Terranova was the first to acknowledge the existence of a Sicilian Mafia Commission. He based himself on a confidential report of the Carabinieri of 28 May 1963, where a confidential informant revealed the existence of a commission composed of fifteen persons – six from Palermo city and the rest from towns in the province – "each with the rank of boss of either a group or a Mafia family." Judge Terranova did not believe that the existence of a commission meant that the Mafia was a tightly unified structure.Gambetta, The Sicilian Mafia, p. 112
