Chattanooga jury-tampering trial

The Chattanooga jury-tampering trial was the prosecution that finally sent Jimmy Hoffa to prison: a case built around attempts to manipulate the jury in an earlier trial, and a courtroom fight over whether the government had planted a witness inside Hoffa’s circle. Its decisive turn came after months of proceedings, when Edward Grady Partin appeared as the government’s last witness and linked Hoffa to the alleged bribery efforts. The trial ended with Hoffa convicted and sentenced to eight years, while Partin’s role became the subject of a major constitutional appeal.

Background and Stakes

Hoffa’s Test Fleet trial in Nashville had been a misdemeanor case under the Taft–Hartley Act. The government alleged that a car-hauling company had been placed in the names of Hoffa’s wife and the late Owen Bert Brennan after Hoffa settled a strike favorably for an employer who later did business with the company. In the government’s account, Test Fleet formed part of a long-term arrangement through which the employer would pay Hoffa. The activity had ended five years earlier and had already been investigated by the McClellan Committee and the Justice Department.

The Nashville trial also produced evidence of attempts to influence prospective jurors. A prospective juror told Judge Miller that a neighbor had offered him $10,000 in hundred-dollar bills to vote for acquittal if selected. Other prospective jurors said a supposed reporter named Allen had called to ask their views of Hoffa; no such reporter worked for the Nashville Banner, and the tainted panel members were dismissed. Jury tampering, if proved, transformed the stakes: conduct connected to a misdemeanor prosecution could itself constitute a felony.

The Chattanooga trial was scheduled to begin on January 20, 1964, with a separate Sun Valley pension-fund trial set for April. Robert F. Kennedy remained attorney general after the assassination of his brother, John F. Kennedy, and the Get Hoffa Squad stayed intact. The squad’s strategy was to bring successive cases against Hoffa. In the account Frank Sheeran gives of this period, the new trial followed closely on the signing of the first Master Freight Agreement in Chicago. Four days after that signing, Hoffa was back in court in Chattanooga.

Partin’s Position and the Government’s Case

Sheeran describes a crowded courtroom and a defense team that included Bill Bufalino and Frank Ragano, alongside lawyers for the other defendants. Allen Dorfman, who ran the pension fund, was also indicted in connection with the jury-tampering scheme. Chuckie O’Brien was present with Hoffa. Sheeran left Tennessee after a few days, believing that the government had evidence against some defendants but no witness capable of tying Hoffa to the conduct. He did not yet know that prosecutors were holding Partin back.

Partin had been kept out of sight in a cabin on Lookout Mountain. The government did not have to identify its witnesses in advance, and his name was saved until the end. The prosecution first called witnesses to establish cases against Hoffa’s associates, the people said to have carried out the work during the Nashville trial. Hoffa, meanwhile, appeared confident and behaved cordially in court.

Partin’s earlier access to Hoffa had begun in Nashville. The Get Hoffa Squad later denied that it violated Hoffa’s constitutional rights by encouraging Partin to join Hoffa’s entourage, but Walter Sheridan acknowledged supplying him with a recording device for calls with Hoffa. Sheridan said he had directed Partin to watch for attempts to bribe jurors. The government’s account was that Partin volunteered to attend, reported to Sheridan—not to the prosecutors—and passed on evidence of continuing jury tampering. Sheridan then relayed that information to the prosecutors, who took it to the judge. The government maintained that Partin had not discussed with Sheridan anything he heard in Nashville about the Test Fleet case or Hoffa’s defense in that case.

The Witness Who Changed the Trial

On the final day, nearly three months into the proceedings, the government called Partin. His entrance caused an uproar, and the defense immediately moved to bar his testimony, arguing that the government had planted a mole in Hoffa’s camp and violated Hoffa’s right to counsel. If the court excluded Partin’s evidence, the defense argued, Hoffa could again leave court a winner.

The judge held a four-hour hearing on the motion and accepted the government’s account. The jury returned, and Partin testified. He connected Hoffa to specific instances of jury tampering by recounting Hoffa’s own boasts about attempts to bribe jurors, including attempts described before they occurred or while they were under way. In the book’s telling, those details shifted the case: the conduct that had seemed to belong to Hoffa’s associates now pointed to Hoffa as the person directing it.

Partin endured almost five days of cross-examination. A defense lawyer accused him of memorizing and rehearsing his testimony; Partin answered that if he had rehearsed it, he would have said more, since he had forgotten some things. The account says he grew stronger under questioning rather than breaking down. During his testimony, a shotgun was fired into the Baton Rouge home of his business agent and friend, a stark incident alongside the courtroom contest over Partin’s credibility.

Hoffa’s anger became increasingly visible. He hurled obscenities at Sheridan when they crossed paths, made a false remark about Sheridan having cancer, and berated his own lawyers in public. He also threatened the prosecutor, James Neal, saying he would hound him for the rest of his life. The trial thus made the conflict over Partin personal and theatrical as well as legal: the government’s witness remained on the stand, while Hoffa’s confidence gave way to outbursts directed at the people he blamed.

Verdict and Sentencing

In closing, Neal characterized the Nashville conduct as one of the greatest assaults on the jury system and argued that Partin’s account was corroborated because events he said had happened, or would happen, did happen. Lead defense attorney James Haggerty called the prosecution a frame-up and attacked Sheridan as the architect of a plot against Hoffa, invoking Kennedy’s name in an effort to discredit the government’s campaign. Another defense summation also attacked Kennedy and Sheridan.

The jury acquitted Dorfman, whose role in the jury-tampering conduct was described as minimal, but convicted Hoffa and three other defendants who had acted on his behalf. Two men in separate trials were also convicted for their roles. At sentencing on March 12, 1964, Hoffa received eight years. His three convicted codefendants received three years each; a jury fixer sentenced in a separate trial received five years, and Nashville lawyer Tommy Osborn received three and a half years. Schiffer received sixty days in jail for contempt, while Ragano was publicly reprimanded for listening at the jury-room door during the trial.

Judge Frank W. Wilson told Hoffa that the court considered his conduct knowing and corrupt, and stressed that it continued even after the trial judge had reported information about an alleged attempt to bribe a juror. The judge described the offense not simply as a violation of individual property or personal rights, but as tampering with the very soul of the nation. The sentence marked a sharp reversal from Hoffa’s earlier trial victories: the government had secured a conviction against the central figure it said could profit from the scheme.

Appeal and Lasting Legal Dispute

Hoffa appealed, and the U.S. Supreme Court agreed to hear the case because it raised a novel question about the constitutional right to counsel and Partin’s presence at the Andrew Jackson Hotel. The appeal came during the criminal-law revolution of 1961–1971, when courts were actively defining protections for criminal defendants. The prosecution team, Walter Sheridan later wrote, was unsure how the justices would rule after oral argument.

The Court ruled against Hoffa on the merits. Justice William Brennan joined the majority opinion, written by Justice Potter Stewart; Chief Justice Earl Warren dissented and voted to reverse the conviction, calling the government’s covert use of Partin an affront to fair federal law enforcement. The appeal preserved a distinction central to the episode: the jury had accepted Partin’s testimony and convicted Hoffa, while the legality and fairness of the government’s method remained sharply contested. In Sheeran’s retrospective account, the trial is also the moment when the government’s previously unseen witness emerged from concealment and changed the outcome of the case.
