Federal cases are decided in the presentence report

People picture federal sentencing as a hearing where a judge listens and decides. There is a hearing, and the judge does decide. But by the time anyone stands up, a probation officer has already produced a document that contains the entire calculation, and the range in it is where the conversation starts.

That document is the presentence investigation report. Contesting it, in writing, on time, is the single highest value activity in most federal cases.

What the arithmetic looks like

The Sentencing Guidelines produce a number from two axes. The offense level comes from a base figure for the offense, adjusted by specific offense characteristics: drug quantity, loss amount, number of victims, role in the offense, obstruction, and acceptance of responsibility. The criminal history category comes from prior convictions scored on their own rules.

Those two coordinates meet on a table and produce a range in months. Statutory mandatory minimums then sit on top, and where they apply they can override the range entirely.

Where the contests are

• Quantity attribution in conspiracy cases. You are accountable for what was reasonably foreseeable to you within the scope of your agreement, not for everything the conspiracy did. That is frequently overstated in a first draft.
• Loss calculation in fraud cases. Intended loss versus actual loss, credits against loss, and double counting where an offset has already been applied.
• Role adjustments. An aggravating role adds levels; a mitigating role subtracts them. Both are fact intensive and both are argued on the record rather than assumed.
• Grouping. Whether counts group together or stack changes the combined offense level, and the rules are technical enough that errors are common.
• Criminal history scoring. Stale convictions, consolidated sentences and offenses that should not have been counted at all.

Safety valve

For qualifying defendants in drug cases, 18 U.S.C. 3553(f) allows a court to sentence below a statutory mandatory minimum. The eligibility criteria were broadened by the First Step Act in 2018, and the practical effect is that more people qualify than the folklore suggests.

It is worth being clear about what safety valve is not. It does not require testifying against anyone. It requires truthful disclosure to the government about your own conduct, which is a materially different thing from cooperation, and one of the most common misunderstandings we correct in a first meeting.

Variance under 3553(a)

Even after the guideline range is settled, the court must consider the factors in 18 U.S.C. 3553(a): the history and characteristics of the defendant, the need for the sentence imposed, and the need to avoid unwarranted disparities among similar defendants.

A variance argument is not a plea for sympathy. It is a package: treatment records, employment verification, family circumstances documented rather than asserted, and comparative data on what similarly situated defendants have received. Assembled properly it is evidence, and judges treat it as evidence.

The timing point

Objections to the presentence report have deadlines, and they are short. A sentencing memorandum filed the week before a hearing, arguing points that should have been raised as formal objections weeks earlier, is a substantially weaker document.

If you are in a federal case and you have not yet been interviewed by probation, that interview is not a formality. Prepare for it the way you would prepare for testimony, because what is said there ends up in the report, and what is in the report is what the court reads first.
