The leverage is built into the structure.
Federal prosecutors often enter plea negotiations holding far more charging and sentencing leverage than the accused.
The government's own numbers
98%
of federal cases that ended in a sentence in fiscal year 2025 were resolved by a guilty plea. It was 97% in fiscal year 2024.
That does not prove coercion in any individual case. It shows that plea bargaining is the dominant operating model.
21%
of federal cases in fiscal year 2025 carried a statutory mandatory minimum penalty.
Mandatory minimums can sharply reduce a judge's sentencing discretion, which intensifies bargaining leverage.
21 vs. 110
months: the median prison term after a guilty plea compared with after a jury-trial conviction, in an independent analysis of Sentencing Commission data for fiscal years 2020 to 2025.
The analyst cautions that selection effects account for part of the difference: trial cases can be more serious and materially different.
Charge stacking and bargaining leverage
Charge stacking
Federal prosecutors can charge multiple statutes, multiple counts, conspiracy counts, substantive counts, sentencing enhancements, and offenses carrying mandatory minimum penalties when the facts and law support them. Each additional count can increase exposure and bargaining pressure.
Mandatory minimums
These statutes can sharply reduce a judge's sentencing discretion. In fiscal year 2025, 21% of federal cases carried one, according to the Sentencing Commission.
Control of the charges
Prosecutors decide whether to file certain charges, dismiss counts as part of a plea agreement, or move for substantial-assistance relief. That discretion can create a large difference between the risk of trial and the negotiated outcome.
The Supreme Court has held that plea bargaining may include a prosecutor threatening to pursue a more serious charge if a defendant rejects a plea, so long as the more serious charge is one the prosecutor has probable cause to bring. In Bordenkircher v. Hayes, the defendant rejected a five-year plea offer and was then subjected to a habitual-offender charge carrying life imprisonment.
The “trial penalty”
Critics use the term “trial penalty” to describe the large sentencing gap that can exist between defendants who plead guilty and defendants who go to trial and are convicted.
The raw gap is not proof that judges or prosecutors unlawfully punish every defendant for exercising the right to trial. Trial cases can be more serious and materially different. But the size of the gap is a central reason defendants may perceive the choice as this: accept a known sentence now, or risk a dramatically larger sentence after trial.
The pressure is built from several parts working together: multiple counts, enhancements and mandatory minimums create enormous trial exposure. The prosecutor may then agree to dismiss or avoid some of that exposure in exchange for a guilty plea. The result is a system in which almost every federal conviction is obtained by plea rather than trial.
When does hard bargaining become a constitutional violation?
