A Fatico hearing is an evidentiary proceeding held during federal sentencing where the judge resolves disputed facts that could change the length of a defendant’s sentence. Both sides put on witnesses and evidence, the judge makes findings, and those findings feed directly into the Sentencing Guidelines calculation. The catch is the standard of proof: the government only has to show a disputed fact is more likely true than not, a far lower bar than the beyond-a-reasonable-doubt standard that governed the trial.
The name comes from United States v. Fatico, a Second Circuit case involving a defendant who pleaded guilty to conspiracy charges tied to truck hijackings at Kennedy Airport and then objected to a presentence report claim that he was a “made” member of the Gambino crime family. The district court held one of the first formal evidentiary hearings devoted entirely to resolving a contested sentencing fact,1Justia. United States v. Fatico, 458 F. Supp. 388 (E.D.N.Y. 1978) and the Second Circuit’s follow-on opinion set the framework federal courts still use.2Justia. United States v. Fatico, 603 F.2d 1053 (2d Cir. 1979) The underlying premise is a long-standing rule: federal courts face no statutory limit on the information they can consider about a defendant’s background, character, and conduct at sentencing.3Office of the Law Revision Counsel. 18 USC 3661 – Use of Information for Sentencing
When a Fatico Hearing Gets Triggered
These hearings are not automatic. They grow out of the presentence investigation required under Federal Rule of Criminal Procedure 32. After a conviction or guilty plea, a probation officer prepares a presentence report that summarizes the offense, the defendant’s criminal history, and the recommended guidelines range.4United States Courts. Presentence Investigations Each side then has a window to file written objections to anything in the report they think is wrong: drug quantities, the defendant’s role in the offense, the dollar amount of loss, whether a weapon was involved, and so on.5Legal Information Institute. Federal Rules of Criminal Procedure Rule 32 – Sentencing and Judgment
If those objections involve facts significant enough to change the guidelines calculation, the court can allow both sides to put on evidence. That evidentiary session is the Fatico hearing. Whether to hold one is the judge’s decision. The Sentencing Guidelines commentary recognizes that an evidentiary hearing “may sometimes be the only reliable way to resolve disputed issues,” while noting that written statements or affidavits may be enough in less contentious situations.6United States Sentencing Commission. Guidelines Manual Chapter 6 – Sentencing Procedures, Plea Agreements, and Crime Victims’ Rights – Section 6A1.3 Judges are more likely to hold one when the disputed fact would materially move the guidelines range, such as a disagreement over whether a fraud caused $500,000 or $5 million in losses.
The Standard of Proof
This is where the hearing does its real damage or its real good, depending on which side you sit. At trial, the government had to prove guilt beyond a reasonable doubt. At a Fatico hearing, the standard drops to a preponderance of the evidence, meaning the judge only needs to conclude that a disputed fact is more likely true than not.7United States Sentencing Commission. Amendment 574 In rough terms, preponderance is about a 51 percent likelihood, while clear and convincing evidence sits closer to 75 or 80 percent. The gap between those standards can decide whether an enhancement sticks.
The original Fatico case actually applied a stricter test. The Second Circuit found the government’s evidence met the “clear, unequivocal and convincing” threshold, estimating at least an 80 percent probability that the defendant was an organized crime member.2Justia. United States v. Fatico, 603 F.2d 1053 (2d Cir. 1979) Over time, most federal circuits settled on preponderance as the default for sentencing facts.
How the Hearing Runs
A Fatico hearing looks less like a trial and more like a focused evidentiary session in front of the judge alone. There is no jury. Both sides present evidence and call witnesses, and the rules are noticeably looser than at trial. Federal law lets courts consider information at sentencing that would be inadmissible during the guilt phase, and the Federal Rules of Evidence, other than the privilege rules, do not apply.2Justia. United States v. Fatico, 603 F.2d 1053 (2d Cir. 1979)
That means hearsay can come in, as long as the judge finds it sufficiently reliable. In the original case, the government called FBI agents to testify about what confidential informants had told them. The Second Circuit allowed it, holding that due process does not bar out-of-court statements by unidentified informants at sentencing as long as there is good cause for nondisclosure and the information is corroborated.2Justia. United States v. Fatico, 603 F.2d 1053 (2d Cir. 1979)
Prosecutors carry the burden on any disputed fact they want the judge to adopt. They typically rely on law enforcement testimony, forensic analysis, financial records, and cooperating witness accounts. In drug cases, that often means an agent testifying about the total quantity attributable to a conspiracy. In fraud cases, it might be a forensic accountant walking through a loss calculation. The government’s aim is to establish a factual picture that supports a higher offense level.
Defense counsel uses the hearing to push back on the government’s version and press for a lower offense level. Cross-examination does most of the work, particularly when the witnesses are cooperators with their own sentencing incentives to overstate. The defense can call its own witnesses, put on expert testimony contesting the government’s numbers, and offer alternative interpretations of the evidence. Successfully knocking down a drug quantity or loss figure at this stage can drop the guidelines range by several levels, which in practical terms can mean years off the sentence.
Relevant Conduct and Acquitted Conduct
Two features of federal sentencing law make Fatico hearings especially consequential.
Relevant Conduct
The Sentencing Guidelines do not confine the judge to the specific crime of conviction. Under the relevant conduct provision, the court considers a broader range of behavior connected to the offense, including acts that were never charged. The guidelines define relevant conduct as the full range of activity that bears on the offense level, balancing what the defendant was convicted of against what actually occurred.8United States Sentencing Commission. Primer on Relevant Conduct (2025) A defendant convicted of distributing one kilogram of drugs might be sentenced based on the ten kilograms the judge attributes to the broader conspiracy. The Fatico hearing is often where that quantity gets fought out.
Acquitted Conduct
The more startling feature is that a judge can raise a sentence based on conduct a jury found the defendant not guilty of. The Supreme Court endorsed the practice in United States v. Watts, holding that an acquittal does not stop the sentencing court from considering the same underlying conduct, so long as it is proven by a preponderance of the evidence.9Justia U.S. Supreme Court Center. United States v. Watts, 519 U.S. 148 (1997) The reasoning is that an acquittal only means the government failed to prove the charge beyond a reasonable doubt; it does not mean the underlying facts are false under the lower preponderance standard. A defendant can walk out of trial acquitted on several counts and still face a sentence heavily shaped by those counts at a Fatico hearing.
How the Findings Translate Into Prison Time
The factual findings feed straight into the guidelines math. The guidelines assign each offense a base level and then move that level up or down based on specific characteristics. Combined with the defendant’s criminal history category, the offense level produces a sentencing range expressed in months.10United States Sentencing Commission. An Overview of the Federal Sentencing Guidelines Moving up just two offense levels might add 12 to 24 months to the range, depending on where the defendant falls on the sentencing table.
Since United States v. Booker in 2005, the guidelines are advisory rather than mandatory. The Supreme Court held that the Sixth Amendment prohibits mandatory guidelines that raise a sentence based on facts found by a judge rather than a jury, and it excised the provision making the guidelines binding.11Justia U.S. Supreme Court Center. United States v. Booker, 543 U.S. 220 (2005) Judges still calculate the range, but they also weigh broader statutory factors, including the nature of the offense, the defendant’s history, deterrence, and the goal of avoiding unwarranted disparities among similar defendants.12Office of the Law Revision Counsel. 18 USC 3553 – Imposition of a Sentence
Advisory does not mean unimportant. Judges anchor heavily to the calculated range, and appellate courts review whether the sentence is substantively reasonable in light of that range. A Fatico finding that pushes the range from 70–87 months to 121–151 months will almost always pull the actual sentence upward, even if the judge is not technically required to sentence inside the range.
Your Rights at the Hearing
The right to counsel carries through. Federal Rule of Criminal Procedure 44 guarantees appointed counsel to any defendant unable to afford an attorney “at every stage of the proceeding from initial appearance through appeal,” and sentencing falls within that protection.13Legal Information Institute. Federal Rules of Criminal Procedure Rule 44 – Right to and Appointment of Counsel
The right to confront witnesses is narrower than at trial. Federal courts have generally held that the Confrontation Clause does not apply at sentencing with the same force it carries during the guilt phase. In practice, you can cross-examine witnesses who actually take the stand, but the judge can also consider hearsay from witnesses who do not appear. The defense’s route is to attack the reliability of that hearsay, not to exclude it outright.
After the Hearing
Once the judge makes findings, they get folded into the sentencing record. The probation officer may revise the presentence report to reflect the court’s determinations, and the judge uses the updated calculations to impose the sentence. The parties can still file objections about how the findings map onto the guidelines, but the factual disputes themselves are settled at that point.
An appeal is available if the defense believes the judge made factual errors or imposed an unreasonable sentence. Appellate courts review Fatico findings for clear error, which means they will only overturn a finding that is clearly wrong on the record. That deference makes it hard to reverse a well-supported Fatico finding, and the appellate court will also assess whether the overall sentence is reasonable in light of the guidelines and the statutory factors.12Office of the Law Revision Counsel. 18 USC 3553 – Imposition of a Sentence
If you are heading into one of these hearings, treat it with the seriousness of a mini-trial. The facts litigated here carry real sentencing weight, the government’s burden is lighter than it was at trial, and a prepared challenge to the evidence can meaningfully reduce a sentence that would otherwise be handed down on the government’s numbers.
