The Mafia Commission Trial — The Five Families Prosecution
New York City, 1985–1987 — Solved federal RICO case
Published June 3, 2026

Quick Facts
The Case
The Mafia Commission Trial was a landmark federal prosecution that targeted the highest levels of organized crime in New York City. Announced on February 26, 1985, the case represented the culmination of a five-year FBI investigation into the leadership structure of the Five Families — the Gambino, Genovese, Lucchese, Colombo, and Bonanno crime families that had controlled organized criminal activity in New York for decades.
Led by U.S. Attorney Rudolph Giuliani, the prosecution employed the Racketeer Influenced and Corrupt Organizations (RICO) Act to charge 11 defendants with operating a criminal enterprise through the Mafia Commission, an organizational body that coordinated activities and settled disputes among the families. The trial marked a watershed moment in federal law enforcement's battle against organized crime, demonstrating that even the most powerful mob bosses could be held accountable under federal statutes.
The Crime
Unlike traditional criminal cases centered on a single violent act, the Mafia Commission Trial prosecuted a pattern of racketeering activity spanning years. The indictment charged defendants with operating a criminal enterprise that engaged in extortion, labor racketeering, illegal gambling, loansharking, narcotics trafficking, and murder conspiracy.
Timeline
8 defendants found guilty
On November 19, 1986, the jury reaches its verdict: 8 of the 11 defendants are found guilty on the RICO charges.
Sentences handed down: most get 100 years
On January 13, 1987, most of the convicted are sentenced to 100 years in prison at the same court in New York. Anthony Indelicato receives a lighter sentence.
The Five Families had long controlled various sectors of New York's economy through intimidation and corruption. Their influence extended into labor unions, construction, garbage collection, and the garment industry. The Mafia Commission itself served as a governing body that allocated criminal territories, approved murders of high-ranking members, and mediated conflicts between families.
Among the specific criminal acts referenced in the prosecution was the murder of Carmine Galante, a Bonanno family leader whose 1979 assassination had been sanctioned by the Commission. The case also detailed systematic extortion schemes in the construction industry, where contractors were forced to pay tribute to secure labor peace and avoid work stoppages orchestrated by mob-controlled unions.
The defendants included some of the most powerful figures in organized crime: leaders and underbosses who had risen through the ranks of their respective families over decades. The prosecution alleged that these men used violence and the threat of violence to maintain their criminal empire, enriching themselves while corrupting legitimate businesses and labor organizations.
The Victims
The Mafia Commission Trial differed from conventional criminal prosecutions in that it did not center on individual victims in the traditional sense. Instead, the case addressed systemic victimization of New York's business community, labor force, and general public through decades of organized criminal activity.
Businesses across multiple industries were victims of extortion schemes, forced to pay protection money or inflated prices to mob-connected companies. Construction projects faced cost overruns due to no-show jobs and rigged bidding processes controlled by the families. Workers in mob-influenced unions saw their pension funds looted and their labor rights subordinated to criminal interests.
The prosecution did reference specific homicides in its racketeering charges, including the murder of Carmine Galante, whose killing exemplified the Commission's power to authorize executions. Other murders and attempted murders formed part of the pattern of racketeering activity that prosecutors used to demonstrate the criminal enterprise's violent nature.
Investigation
The investigation that led to the Mafia Commission Trial represented one of the most extensive federal organized crime probes in American history. Beginning around 1980, FBI agents employed sophisticated surveillance techniques, wiretaps, and informant testimony to penetrate the secretive world of the Five Families.
For five years, federal investigators gathered evidence of the Commission's operations and the individual families' criminal activities. They documented meetings, recorded conversations, and built a comprehensive picture of how the Mafia Commission functioned as a governing body for organized crime in New York.
The investigation benefited from developments in electronic surveillance technology and from the RICO statute itself, which allowed prosecutors to charge defendants with participation in a criminal enterprise rather than requiring proof of individual crimes. This legal framework enabled authorities to target the organizational structure of the mob, not just individual criminal acts.
Rudolph Giuliani, then serving as U.S. Attorney for the Southern District of New York, coordinated the prosecution strategy. His approach focused on dismantling the leadership structure of organized crime by prosecuting the Commission members themselves, rather than lower-level operatives who could easily be replaced.
Trial and Verdict
The trial proceedings captivated public attention as prosecutors laid out evidence of how the Mafia Commission operated. Witnesses testified about the families' control over various industries, the Commission's role in authorizing murders, and the systematic corruption that had infiltrated legitimate businesses.
The prosecution presented wiretap recordings, surveillance photographs, and testimony from cooperating witnesses who had participated in organized crime activities. The evidence painted a detailed picture of a sophisticated criminal organization that had operated with relative impunity for decades.
On November 19, 1986, the jury returned guilty verdicts against eight defendants on racketeering and conspiracy charges. The convictions represented a stunning victory for federal prosecutors and a devastating blow to New York's organized crime families.
Sentencing took place on January 13, 1987, when the judge imposed 100-year prison terms on most of the convicted defendants — the maximum possible sentence under federal guidelines. These harsh sentences reflected both the severity of the crimes and the court's determination to permanently remove these organized crime leaders from society.
The convictions were largely upheld on appeal, cementing the legal precedent that the RICO statute could effectively be used against organized crime's highest echelons.
Today
The Mafia Commission Trial fundamentally altered the landscape of organized crime in New York and established a blueprint for federal prosecutions of criminal enterprises. The successful use of RICO statutes demonstrated that even the most powerful mob bosses could be held accountable under federal law.
The case effectively decapitated the leadership of the Five Families, creating power vacuums that led to internal conflicts and weakened the organizational structure of New York's Mafia. While organized crime continues to exist, it has never regained the level of power and influence it wielded before the Commission Trial.
Rudolph Giuliani's role in the prosecution launched his political career, eventually leading to his election as New York City Mayor. The trial remains a landmark in American legal history and continues to be studied in law schools as an example of effective use of racketeering statutes.
The case has been the subject of numerous books, documentaries, and academic studies examining both the criminal enterprise it dismantled and the legal strategies that made the prosecution successful. It stands as a defining moment in the federal government's decades-long battle against organized crime in America.
