Yes. You can face both state and federal charges for the same crime, and the U.S. Supreme Court has upheld this arrangement as recently as 2019. The Fifth Amendment’s ban on double jeopardy blocks the same government from trying you twice for the same offense, but state and federal governments are treated as separate sovereigns with separate laws. When your conduct breaks both, the Constitution sees two offenses, not one.
Why Double Jeopardy Doesn’t Stop It
The Fifth Amendment says no person shall “be subject for the same offense to be twice put in jeopardy of life or limb.”1Legal Information Institute. Fifth Amendment Once a government has tried you and you’ve been acquitted or convicted, that same government cannot come after you again for the same crime. The protection stops prosecutors from wearing defendants down through repeated trials.
The word that does the heavy lifting is “same.” Courts read “same offence” to mean the same offense against the same sovereign. A robbery that violates Georgia law is a different offense than a robbery that violates federal law, even though you did one thing. That reading is the dual sovereignty doctrine: the federal government and each state draw their authority from different sources, each writes its own criminal code, and each has its own interest in enforcement.2LII / Legal Information Institute. Separate Sovereigns Doctrine
The Supreme Court reaffirmed the doctrine in 2019 in Gamble v. United States. Terance Gamble was pulled over in Mobile, Alabama for a damaged headlight. Police found a loaded handgun, and because Gamble had a prior robbery conviction, he was charged under Alabama’s felon-in-possession law and pleaded guilty. Federal prosecutors then indicted him for the same possession under federal law. Gamble argued double jeopardy. The Court rejected his argument 7-2, holding that Alabama and the federal government are separate sovereigns and the two prosecutions targeted two different offenses.3Justia. Gamble v United States Justice Alito’s majority opinion framed dual sovereignty not as an exception to double jeopardy but as a direct consequence of its text.4Oyez. Gamble v United States
When It Typically Happens
Dual prosecution doesn’t come up with every crime. It comes up when a single act happens to harm interests that both a state and the federal government have separately decided to protect. A few categories are common.
- Bank robbery. Robbing any bank violates state theft laws. Federal law separately criminalizes robbing any bank whose deposits are FDIC-insured, which covers nearly every bank in the country. One holdup, two sovereigns.5Office of the Law Revision Counsel. 18 USC 2113 – Bank Robbery and Incidental Crimes
- Kidnapping. Holding someone against their will is a state crime everywhere. Once the victim is transported across a state line, federal kidnapping law applies as well.6Office of the Law Revision Counsel. 18 USC 1201 – Kidnapping
- Drug trafficking. Large-scale drug operations tend to violate both state controlled-substance laws and the federal Controlled Substances Act, particularly when drugs cross state lines or quantities meet federal trafficking thresholds.
- Civil rights violations. A police officer who uses excessive force can face state assault charges and a separate federal prosecution under civil rights statutes. This scenario has played out in several high-profile cases where federal authorities considered the state result inadequate.
The Limits That Actually Apply
The Constitution permits dual prosecution, but three things keep it from happening in every eligible case.
The DOJ’s Petite Policy
The Department of Justice follows an internal guideline called the Petite Policy, named after the 1960 Supreme Court case Petite v. United States.7Legal Information Institute. Petite v United States Under it, a federal prosecutor cannot bring charges based on the same acts already prosecuted in state court unless three conditions are met. The case must involve a substantial federal interest. The state prosecution must have left that interest “demonstrably unvindicated.” And the evidence must be strong enough to obtain and sustain a conviction. On top of that, the prosecutor needs prior approval from the appropriate Assistant Attorney General before filing.8United States Department of Justice. Justice Manual 9-2.000 – Authority of the US Attorney in Criminal Division Matters/Prior Approvals
Most potential dual prosecutions die at this stage. The “demonstrably unvindicated” standard is deliberately high. A prosecutor who simply thinks a state sentence was too lenient doesn’t automatically get a green light.
One catch matters for defendants. The Petite Policy is internal DOJ guidance, not a legal right. You cannot walk into court and argue that the policy bars your federal case. If the DOJ ignores its own policy, the remedy is administrative, not judicial.
Federal Statutes That Bar Dual Prosecution
For a handful of specific crimes, Congress went further than the Constitution requires. For offenses like theft from interstate shipments, embezzlement from certain carriers, and certain riot-related crimes, federal law explicitly provides that a state conviction or acquittal bars a subsequent federal prosecution for the same act. Unlike the Petite Policy, these statutory bars are real rights a defendant can enforce.8United States Department of Justice. Justice Manual 9-2.000 – Authority of the US Attorney in Criminal Division Matters/Prior Approvals The carve-outs are narrow, though. For the vast majority of federal crimes, no such bar exists.
State Laws With Broader Protection
Some states have voluntarily restricted their own ability to prosecute someone already tried in federal court for the same conduct. These states enacted statutes or constitutional provisions giving residents broader double jeopardy protection than the federal Constitution requires. The details vary. Some bar state prosecution entirely after a federal conviction or acquittal. Others allow it only in narrow circumstances, such as when the federal case was dismissed on a technicality rather than resolved on the merits. If you’re facing potential dual prosecution, whether your state offers this kind of protection is one of the first things worth checking with a lawyer.
What Dual Convictions Mean for Your Sentence
If you’re convicted in both courts, do you serve two full sentences back-to-back, or do they overlap? It depends on timing, judicial discretion, and federal sentencing guidelines.
Under federal law, when a court sentences someone already serving an undischarged sentence from another case, the default is that the sentences run consecutively. The judge, however, has discretion to order them concurrent instead.9Office of the Law Revision Counsel. 18 USC 3584 – Multiple Sentences of Imprisonment When both sentences are imposed at the same time, the default flips to concurrent unless the court orders otherwise.
Federal sentencing guidelines add another layer. Under USSG 5G1.3, when a defendant has an undischarged state sentence for conduct that is “relevant conduct” to the federal offense, the federal court is directed to run its sentence concurrently with the remaining state sentence and to adjust for time already served on the state charge, provided the Bureau of Prisons won’t independently credit that time. The goal is a combined punishment that reflects the total seriousness of the conduct without double-counting time.
In practice, dual convictions don’t always double the prison time. But they can. A federal judge who considers the state sentence far too lenient has discretion to impose a consecutive sentence, and some do. The worst-case outcome is finishing a state sentence and then starting a full federal sentence for the same underlying conduct.
What Acquittal in One Court Means for the Other
An acquittal in one jurisdiction does not prevent prosecution in the other. If a state jury finds you not guilty, federal prosecutors can still bring their own case based on the same facts. The factual findings from the first trial generally do not bind the second sovereign. This is the flip side of dual sovereignty that troubles the doctrine’s critics most: the government effectively gets two chances to convict, wearing different jerseys each time.
If you’re facing charges from one government and think the other may be watching, that possibility should shape your defense strategy from the beginning. A plea, a statement, or a trial record built for a state case can follow you into federal court, and vice versa. This is one of the situations where having a lawyer who understands both systems matters most.
