State vs Federal Prosecution Differences

State vs Federal Prosecution Differences

Can you be prosecuted twice for the same crime? Most people thinks the answer is no – that’s what Double Jeopardy means, right? Wrong. Irregardless of what you learned in civics class, you absolutely can be tried in both state and federal court for the exact same conduct. This ain’t a loophole. This is constitutional law, and if your facing criminal charges right now, you needs to understand how this works before it’s too late. The difference between state prosecution and federal prosecution is gonna determine you’re entire future – your conviction odds, you’re sentence length, and whether you ever see freedom again. This article is gonna break down everything you needs to know about state vs federal prosecution differences, including jurisdiction triggers, conviction rates, sentencing guidelines, and when federal prosecutors decides to adopt state cases.

The Dual Sovereignty Trap Nobody Tells You About

Here’s the reality that shocks most defendants: the state and federal governments are separate “sovereigns” under the Constitution, which means both can prosecute you for the same conduct without violating Double Jeopardy protections. The Fifth Amendment says you can’t be tried twice for the same offense – but “same offense” doesn’t mean what you thinks it means. If you’re conduct violates both a state criminal statute and a federal criminal statute, then you has committed two separate offenses in the eyes of the law, irregardless of the fact that the underlying conduct is identical.

The Supreme Court reaffirmed this principle in Gamble v. United States (2019), where they upheld the dual sovereignty doctrine even though the defendant argued it was fundamentally unfair. More recently, in Smith v. United States (2025), the Court again confirmed that state and federal prosecutions for the same conduct doesn’t violate the Constitution. Between you and I, the courts is never gonna overturn this doctrine – it’s been settled law for over 150 years, and five different Supreme Courts has refused to change it.

Real-world example: Let’s say you robs a bank. You violates the state robbery statute (theft by force or intimidation), but you also violates the federal bank robbery statute (18 USC § 2113), which applies because the bank is federally insured. State prosecutors can charge you with robbery under state law. Federal prosecutors can simultaneously charge you with federal bank robbery. Both cases moves forward in separate court systems. If you’re acquitted in state court, the feds can still prosecute you in federal court. If you’re convicted in state court and serves five years, the feds can then prosecute you and add another 20 years on top. This ain’t double jeopardy based off the Supreme Court’s interpretation – this is dual sovereignty.

Some defendants don’t believe this until they sees it happening. I seen cases where someone gets acquitted in state court, celebrates, and then gets indicted in federal court three months later for the exact same conduct. The celebration don’t last long. Prosecutors on both sides knows about this doctrine, and they uses it strategically. Sometimes state and federal prosecutors coordinates behind closed doors. Other times, they competes to see who gets the case. Either way, you’re at risk of double prosecution anytime you’re conduct could violate both state and federal law.

Jurisdiction Triggers – When Feds Can Prosecute vs When States Prosecute

Understanding jurisdiction is critical because it determines which system – state or federal – has the power to prosecute you. Many, many cases falls into what lawyers calls “concurrent jurisdiction,” meaning both state and federal prosecutors can bring charges. But first, let’s break down when federal jurisdiction gets triggered versus when state jurisdiction applies.

Federal Jurisdiction Gets Triggered When:

• Interstate commerce is involved: If you’re crime affects interstate commerce – which federal courts interprets extremely broadly – then federal prosecutors can charge you. Drug trafficking across state lines, wire fraud using the internet, even local drug dealing (because drugs was transported across state lines at some point) can trigger federal jurisdiction based off the Commerce Clause.
• Crime occurs on federal property: National parks, military bases, federal buildings, post offices, Native American reservations (in many circumstances) – any crime committed on federal property falls under federal jurisdiction irregardless of whether it violates state law too.
• Federal agency is involved in investigation: If the FBI, DEA, ATF, IRS, Secret Service, or any other federal agency investigates you’re case, federal prosecutors is likely gonna adopt it. Federal agencies doesn’t hand off investigations to state prosecutors unless there’s a compelling reason.
• Federal statute is violated: Certain crimes only exists under federal law: bank robbery (federally insured banks), mail fraud, wire fraud, federal firearms violations, immigration violations, federal tax crimes, RICO (racketeering), terrorism offenses, federal drug trafficking statutes, child exploitation under federal law, public corruption cases involving federal funds.
• Crime crosses state lines: Kidnapping across state lines, transporting stolen property across state lines, sex trafficking, drug trafficking – anything where the criminal conduct don’t stay within one state’s boundaries typically triggers federal jurisdiction.
• Federal interests are implicated: Even if the crime occurred entirely within one state, federal prosecutors can adopt the case if substantial federal interests is at stake. This includes cases involving national security, terrorism, civil rights violations, large-scale fraud, organized crime, or public corruption.

State Jurisdiction Gets Triggered When:

• Crime occurs within state boundaries: Most criminal conduct – assault, theft, robbery, murder, DUI, drug possession – occurs entirely within one state and violates state criminal statutes. State prosecutors handles the vast majority of criminal cases in America.
• State statute is violated: Each state has its own criminal code. If you violates a state statute, state prosecutors in that jurisdiction has authority to charge you.
• Local law enforcement investigates: When local police or state police investigates you’re case, it typically stays in state court unless federal agencies gets involved later.
• State/local interests are implicated: Crimes affecting local communities – domestic violence, local drug dealing, property crimes, DUI – typically stays in state court because state prosecutors prioritizes local public safety.

Concurrent Jurisdiction – When BOTH Can Prosecute:

This is where it gets dangerous for defendants. Many crimes creates concurrent jurisdiction, meaning both state AND federal prosecutors can charge you, irregardless of where the case starts. Common examples includes:

• Bank robbery: Violates state robbery laws + federal bank robbery statute (18 USC § 2113)
• Drug trafficking: Violates state controlled substance laws + federal drug trafficking statutes (21 USC § 841)
• Fraud schemes: Violates state fraud laws + federal wire fraud (18 USC § 1343) or mail fraud (18 USC § 1341)
• Weapons offenses: Violates state gun laws + federal firearms statutes (18 USC § 922, § 924)
• Child exploitation: Violates state child abuse/pornography laws + federal CSAM statutes (18 USC § 2251, § 2252)

When concurrent jurisdiction exists, prosecutors on both sides has to decide who’s gonna prosecute. Sometimes they negotiates. Sometimes federal prosecutors adopts the case from state prosecutors (more on that below). Sometimes both prosecutes separately under the dual sovereignty doctrine. You doesn’t get a say in this – the prosecutors makes the call behind closed doors, and you finds out when the indictment drops.

Conviction Rate Reality – 95% Federal vs 68% State

If there’s one statistic that should terrify you about federal prosecution, it’s this: federal prosecutors maintains a conviction rate above 95%. State prosecutors, by contrast, convicts at around 68% on average across all states. That’s a 27-point difference, and it ain’t because federal prosecutors is smarter. It’s because the entire federal system is engineered to produce convictions through plea bargains.

Here’s what them numbers actually means for you: If you’re charged in federal court, you has a 95% chance of being convicted. If you’re charged in state court, you has a 68% chance of being convicted. The forum – state versus federal – determines you’re odds of walking free or spending decades in prison. Irregardless of how strong you thinks you’re defense is, the statistics doesn’t lie.

Why Federal Conviction Rates Is So Much Higher:

1. Selective prosecution (cherry-picking cases): Federal prosecutors doesn’t prosecute everything. They only takes cases where the evidence is overwhelming and conviction is virtually certain. The FBI, DEA, and other federal agencies spends months or even years building cases before seeking indictments. By the time you’re indicted in federal court, prosecutors already has you on wiretaps, cooperating witnesses, financial records, and forensic evidence. They don’t bring weak cases.

2. Trial penalty creates massive plea pressure: The federal system uses what’s called the “trial penalty” to coerce guilty pleas. If you pleads guilty early and “accepts responsibility,” you gets a 2-3 level reduction under the sentencing guidelines. If you goes to trial and loses, you doesn’t get that reduction and you likely faces additional charges that was held back during plea negotiations. The result? Defendants who goes to trial and gets convicted receives sentences that’s 3-5 times longer then defendants who pleaded guilty for the same conduct. This is gonna pressure you into pleading guilty even if you was innocent, because the risk of trial is too high.

3. Resource advantage (FBI vs local police): Federal prosecutors has unlimited resources compared to state prosecutors. The FBI can dedicate agents to you’re case full-time for years. They has forensic accountants, digital forensics experts, wiretap capabilities, and national databases. Local police departments is overworked and under-resourced. The investigation quality in federal cases is dramatically higher, which leads to stronger evidence at trial.

4. Grand jury indictments signals strong evidence: Federal cases requires grand jury indictments (except for misdemeanors). If a grand jury votes to indict you after reviewing the evidence, that signals to trial juries that the case is strong. State prosecutors in many states can proceed by complaint or information without grand jury review, so there’s less external validation of the evidence.

5. Less than 5% of federal cases goes to trial: Federal prosecutors knows they has a 95%+ conviction rate, so they don’t offer good plea deals. Why would they? Defendants folds under the pressure because going to trial in federal court is suicidal. You’re lawyer is gonna tell you the truth: plead guilty and get 5-7 years, or go to trial and risk 20-25 years. Most defendants takes the plea, which means prosecutors almost never has to prove their case at trial. This system perpetuates itself – high conviction rates leads to worse plea offers, which leads to more guilty pleas, which leads to even higher conviction rates.

Why State Conviction Rates Is Lower:

State prosecutors doesn’t have it easy. They prosecutes everything – DUIs, misdemeanor assaults, theft cases, domestic violence, drug possession, all the way up to murder. They can’t cherry-pick only strong cases because they has to respond to every arrest made by local police. Many state cases is weak: witness credibility issues, Fourth Amendment problems, identification issues, lack of physical evidence. State prosecutors also faces resource constraints – overloaded dockets, underfunded public defender offices that actually fights cases, and local juries that’s more sympathetic to defendants then federal juries.

Between you and I, state prosecutors loses cases all the time. Juries acquits. Judges suppresses evidence. Witnesses recants. This is normal in state court. In federal court, acquittals is so rare that it makes the news when it happens. Even more worse, if you somehow beats the feds at trial, they can appeal or bring new charges based off conduct that wasn’t charged initially. The federal system doesn’t like losing.

Sentencing Differences – Federal Guidelines vs State Discretion

Conviction rates ain’t the only difference – sentencing in federal versus state court is night and day. If you’re convicted in federal court, you’re gonna serve dramatically more time then you would for the same offense in state court, irregardless of the specific crime. Here’s why:

Federal Sentencing System:

• Sentencing Guidelines is functionally mandatory: The U.S. Sentencing Guidelines was technically made “advisory” by the Supreme Court in United States v. Booker (2005), but federal judges still follows them in the vast majority of cases. Judges has to calculate the guideline range and can only depart with written justification. If the judge deviates too far, the government appeals and usually wins. So even though guidelines is “advisory,” they operates like mandatory minimums in practice.
• NO parole in federal system: Congress eliminated parole in the federal system in 1987. If you’re sentenced to 10 years in federal prison, you serves approximately 8.5 years minimum (85% of the sentence). There’s no parole board that can release you early based off good behavior. You gets a maximum of 15% “good time” credit, and that’s it. Federal prisoners serve 85% of their sentence minimum – there is no early release.
• Harsh mandatory minimums: Federal drug trafficking statutes has mandatory minimum sentences based off drug quantities. For example, trafficking 500 grams or more of cocaine triggers a 5-year mandatory minimum. Trafficking 5 kilograms or more triggers a 10-year mandatory minimum. Federal firearms statutes also has mandatory minimums – 18 USC § 924(c) requires a 5-year mandatory consecutive sentence if you uses or carries a firearm during a drug trafficking crime or crime of violence. Judges can’t go below these mandatory minimums even if they wants to.
• Supervised release follows prison: After you serves you’re federal prison sentence, you then serves a period of “supervised release” (basically federal probation). If you violates supervised release conditions, you goes back to prison. This can add years to you’re total time under federal custody.

State Sentencing System (Varies by State):

• More judicial discretion: Many states doesn’t have sentencing guidelines at all. Judges has broad discretion to sentence anywhere within the statutory range based off mitigating and aggravating factors. Even in states with guidelines, they’re typically more flexible then federal guidelines.
• Parole still exists in many states: Most states still has parole systems where defendants becomes eligible for parole after serving a percentage of their sentence – often 25-50% depending on the offense and state. Parole boards can release defendants early if they demonstrates rehabilitation. This means a 10-year state sentence might result in 2.5-5 years actually served if parole is granted.
• Probation and suspended sentences is common: State judges can suspend all or part of a sentence and place defendants on probation. This is extremely rare in federal court for felonies but common in state court, especially for first-time offenders or non-violent crimes.
• Mandatory minimums exists but typically less harsh: Some states has mandatory minimums for certain offenses (drug trafficking, firearms crimes), but they’re generally less severe then federal mandatory minimums. State mandatory minimums might requires 2-3 years for conduct that triggers 5-10 years federally.

Real Impact on You’re Sentence:

Let’s compare two identical defendants convicted of the same drug trafficking offense:

Federal defendant: Sentenced to 10 years under federal guidelines. Serves 8.5 years minimum (85% of sentence). NO possibility of parole. Then serves 3-5 years of supervised release after prison. Total time under federal custody: 11.5-13.5 years minimum.

State defendant: Sentenced to 10 years under state law. Becomes eligible for parole after 2.5 years (25% in many states). Parole board releases defendant after 4 years served based off good behavior. Total time in prison: 4 years.

Same crime. Same sentence on paper. The federal defendant serves 8.5 years while the state defendant serves 4 years. That’s the difference between federal and state sentencing, and it’s why federal prosecutors has so much leverage in plea negotiations. Defendants knows that federal time is real time – you serves almost every day of you’re sentence with no hope of early release.

Irregardless of what you was told, federal sentencing is dramatically harsher then state sentencing for equivalent conduct. If you has a choice between federal and state prosecution – and sometimes you does through strategic lawyering – you wants state court every single time based off sentencing alone.

Concurrent Jurisdiction and Forum Shopping

When both federal and state prosecutors can charge you (concurrent jurisdiction), they engages in what’s called “forum shopping” – deciding which court system gives them the best advantage. Prosecutors is gonna negotiate behind closed doors to decide who prosecutes you’re case, and this decision determines you’re entire future. You doesn’t get a vote. You’re lawyer can advocate for state prosecution, but ultimately prosecutors makes the call based off their own strategic considerations.

What Factors Prosecutors Considers When Forum Shopping:

1. Conviction likelihood: Federal prosecutors knows they has a 95%+ conviction rate. State prosecutors knows they has a 68% average conviction rate. If the case has any weaknesses – witness credibility issues, Fourth Amendment problems, identification concerns – federal prosecutors is more likely to adopt it because they has better resources to overcome them weaknesses. If the case is real weak, sometimes prosecutors agrees to keep it in state court where conviction ain’t guaranteed.

2. Sentencing severity: Federal prosecutors can threaten dramatically longer sentences then state prosecutors for the same conduct. This gives federal prosecutors more leverage in plea negotiations. If prosecutors wants to “send a message” or punish a defendant harshly, they moves the case to federal court. If they wants some flexibility or believes the conduct don’t warrant decades in prison, they might keeps it in state court.

3. Investigative resources: The FBI, DEA, ATF, and other federal agencies has resources that local police departments doesn’t have. If the case requires wiretaps, extensive financial analysis, multi-state coordination, or digital forensics, federal prosecutors is better equipped to handle it. Many, many cases gets adopted by federal prosecutors simply because the investigation is too complex for local law enforcement.

4. Jury pool demographics: Federal district courts draws jurors from multiple counties or even entire regions. State courts draws jurors from single counties. Prosecutors analyzes where the jury pool is more likely to convict. If you’re charged in a conservative rural county, state prosecutors might prefer to keep the case local. If you’re charged in a liberal urban county where juries is skeptical of police, federal prosecutors might adopt the case to get a different jury pool.

5. Political considerations: Federal prosecutors is appointed (by the President and confirmed by the Senate) and serves at the pleasure of the Attorney General. State prosecutors (district attorneys) is typically elected by local voters. This creates different incentives. Elected state prosecutors might declines to prosecute cases that’s politically unpopular in their jurisdiction. Federal prosecutors doesn’t face them political constraints and can prosecute cases irregardless of local sentiment.

Common Crimes Where Forum Shopping Occurs:

• Bank robbery: Federal statute (18 USC § 2113) gives feds jurisdiction, but state robbery laws also applies. If the defendant used a firearm, federal prosecutors almost always adopts the case because 18 USC § 924(c) adds a mandatory 5-year consecutive sentence on top of the robbery sentence.
• Drug trafficking: Federal and state drug laws overlaps extensively. Federal prosecutors typically adopts cases involving large quantities, interstate trafficking, or organized distribution networks. Smaller cases stays in state court unless federal agents was involved in the investigation.
• Fraud schemes: Wire fraud and mail fraud is federal crimes, but most states also has fraud statutes. Federal prosecutors adopts cases involving sophisticated schemes, large dollar amounts, multiple victims across states, or use of the internet/mail.
• Child exploitation: Both federal and state laws prohibits child sexual abuse material (CSAM). Federal prosecutors adopts cases involving distribution, production, or large collections because federal mandatory minimums is 5-15 years versus more lenient state sentences.

I seen cases where state prosecutors arrests someone and then federal prosecutors adopts the case three days later because the feds wants the higher conviction rate and harsher sentences. The defendant goes from facing 3-5 years in state court to facing 10-20 years in federal court for the exact same conduct. This is forum shopping in action, and it’s perfectly legal.

Between you and I, prosecutors is gonna forum shop to maximize their advantage every single time. They doesn’t care about fairness – they cares about convictions and sentences. If federal prosecution gives them a better chance of convicting you and putting you away for longer, they’re gonna take the case federal. You’re only hope is having a lawyer who understands these dynamics and can advocate for state prosecution before the decision is made. Once the federal indictment drops, it’s too late.

When Federal Prosecutors Adopts State Cases

One of the most critical moments in any criminal case involving concurrent jurisdiction is when federal prosecutors decides whether to “adopt” the case from state prosecutors. Federal adoption means the feds takes over prosecution, files federal charges, and moves the case to federal court. Once federal prosecutors adopts you’re case, you’re almost certainly gonna be convicted (95%+ rate) and you’re gonna serve dramatically longer sentences then you would’ve in state court. This section is gonna explain when and why federal prosecutors adopts state cases, irregardless of whether state prosecutors wants to give up the case.

DOJ Criteria for Federal Adoption (Justice Manual 9-116.000 and 9-27.000):

The Department of Justice Justice Manual provides guidelines for when federal prosecutors should adopt state/local cases. Here’s what federal prosecutors looks at:

1. Substantial federal interest exists: Federal prosecutors only adopts cases where there’s a “substantial federal interest” in prosecution. This is determined case-by-case, but typically includes cases involving federal law violations, interstate conduct, federal agencies, or federal enforcement priorities. If you’re conduct only violates state law and has no federal dimension, federal prosecutors ain’t gonna touch it.

2. State lacks resources or expertise: Complex cases requiring extensive resources – financial fraud investigations, multi-state drug trafficking conspiracies, cybercrime, public corruption – often gets adopted by federal prosecutors because state prosecutors doesn’t have the investigative tools or expertise to prosecute effectively. The FBI, DEA, IRS, and other federal agencies can dedicate agents full-time to one case for years. Local police can’t.

3. Federal penalties is more severe: Sometimes federal prosecutors adopts cases specifically because federal mandatory minimums is harsher then state penalties. If prosecutors wants to ensure a defendant serves significant prison time, federal adoption guarantees longer sentences with no parole. This is particularly common in drug trafficking and firearms cases where federal mandatory minimums is 5-10+ years while state sentences might be 2-5 years.

4. DOJ enforcement priorities: The Attorney General sets national enforcement priorities each year – public corruption, organized crime, civil rights violations, violent crime, opioid trafficking, cybercrime, etc. If you’re case falls within current DOJ priorities, federal prosecutors is much more likely to adopt it irregardless of whether the state could prosecute. For example, during opioid enforcement pushes, federal prosecutors adopted many, many state-level fentanyl trafficking cases to send a message.

5. Federal forfeiture opportunities: Federal civil asset forfeiture laws is more expansive then most state forfeiture laws. If defendants has significant assets – real estate, cash, vehicles, bank accounts – federal prosecutors can seize them through civil forfeiture even if you ain’t convicted. This financial incentive leads to federal adoption of cases where substantial assets is involved. State prosecutors might not have the same forfeiture tools, so they defers to federal prosecutors who can seize everything.

6. Multi-district or interstate elements: Cases involving conduct across multiple states or federal judicial districts is better suited for federal prosecution because federal prosecutors has jurisdiction nationwide. State prosecutors is limited to their state boundaries. If you was trafficking drugs from California to New York, federal prosecutors can charge the entire conspiracy in one case. State prosecutors would needs separate prosecutions in each state, which is inefficient.

Common Examples of Federal Adoption:

• Public corruption: Federal bribery statutes (18 USC § 201, § 666) is broader then state bribery laws and applies to state/local officials who receives federal funds. Federal prosecutors routinely adopts state corruption cases because federal penalties is harsher and FBI resources is superior.
• Large-scale drug trafficking: Federal drug mandatory minimums is much harsher then state penalties. A defendant facing 5-10 years in state court for trafficking might face 10-20 years federally for the same drug quantities. Federal prosecutors adopts these cases to guarantee longer sentences.
• Organized crime / RICO: The federal RICO statute (18 USC § 1961-1968) allows prosecutors to charge entire criminal organizations and hold leaders accountable for crimes committed by subordinates. Most states doesn’t have equivalent RICO statutes, so federal prosecutors adopts organized crime cases to use this powerful tool.
• Child exploitation: Federal CSAM statutes (18 USC § 2251, § 2252) has 5-15 year mandatory minimums for production and distribution, while state penalties is often more lenient. Federal prosecutors also has better digital forensics resources to trace online conduct. These cases almost always gets adopted if any federal jurisdictional hook exists (interstate transmission, use of the internet).
• Cybercrime: The FBI’s Cyber Division has expertise that state/local law enforcement doesn’t. Cases involving hacking, ransomware, identity theft, or online fraud typically gets adopted by federal prosecutors because they has the technical resources to investigate and prosecute effectively.
• Civil rights violations: Federal civil rights statutes (18 USC § 242, § 245) allows prosecution of state actors (police officers, corrections officers) who violates individuals’ constitutional rights. These cases almost always goes federal because state prosecutors is reluctant to prosecute local law enforcement officers they works with daily.

Federal adoption ain’t no blessing for defendants. Once the feds adopts you’re case, you’re conviction odds jumps to 95%+, you’re potential sentence doubles or triples, and you loses any hope of parole. I seen defendants who was looking at 3-5 years in state court end up with 15-20 years in federal court after adoption, irregardless of the fact that the conduct was identical. The forum change is everything.

What defendants needs to understand: Federal adoption decisions happens early, often before you’re even indicted. If federal agents is investigating you – FBI, DEA, ATF, IRS – then federal prosecutors is already considering adoption. You’re lawyer needs to engage with federal prosecutors immediately to argue against federal adoption. Once the federal grand jury returns an indictment, the adoption decision is final. You can’t appeal it. You can’t challenge it. You’re stuck in federal court with 95% conviction odds and sentences that’s gonna keep you locked up for decades without nothing like parole to give you hope.

DOJ Petite Policy – Limits on Dual Prosecution (and Exceptions)

You might be thinking: “If I gets prosecuted in state court first, doesn’t that protect me from federal prosecution for the same conduct?” The answer is: sometimes, but don’t count on it. The Department of Justice has a policy called the “Petite Policy” (named after Petite v. United States) that’s supposed to limit successive federal prosecutions after state prosecutions. But the policy has so many exceptions that it doesn’t provide much protection, irregardless of what some lawyers might tell you.

The General Rule (Petite Policy):

According to DOJ Justice Manual 9-27.000, federal prosecutors should generally decline to prosecute defendants who has already been prosecuted by state authorities for “substantially the same act or acts” unless certain conditions is met. The policy recognizes that dual prosecutions creates unfairness and wastes resources, so federal prosecutors is supposed to defer to state prosecutions in most cases.

This sounds protective, but here’s the problem: the Petite Policy is just a policy, not a law. It doesn’t creates any constitutional rights. Courts can’t enforce it. If federal prosecutors decides to ignore the policy and prosecute you anyway, you doesn’t have no legal remedy. The policy is entirely discretionary – federal prosecutors decides whether to follow it on a case-by-case basis.

Exceptions – When Federal Prosecutors CAN Still Prosecute After State Prosecution:

The Petite Policy lists several exceptions where federal prosecutors can prosecute you even after state prosecution for the same conduct. These exceptions is so broad that they swallows the general rule:

1. Critical federal interest was not vindicated by state prosecution: If the state conviction doesn’t adequately address federal enforcement goals, federal prosecutors can bring federal charges. For example, if you was convicted of simple assault in state court but the conduct also violated federal civil rights laws, federal prosecutors can prosecute you federally because the state conviction doesn’t vindicate the federal interest in protecting civil rights.

2. State prosecution was inadequate: If federal prosecutors believes the state proceeding was inadequate – too lenient a sentence, biased judge, corrupt process, insufficient investigation – they can prosecute you federally. This exception is extremely subjective. Federal prosecutors essentially gets to second-guess state prosecutors and decides whether the state “did it right.” Many times federal prosecutors argues that state sentences was too lenient, so they brings federal charges to get a harsher sentence.

3. Civil rights violations: Cases involving federal civil rights statutes (18 USC § 242, § 245) almost always meets the exception criteria. Even if a police officer is prosecuted and acquitted in state court for excessive force, federal prosecutors can bring federal civil rights charges for the same conduct. This has happened in many, many high-profile cases – state acquittal followed by federal conviction.

4. National security concerns: Any case involving terrorism, espionage, or national security automatically meets the exception. Federal prosecutors doesn’t defer to state prosecutors when national security is at stake, irregardless of what the state court does.

5. Substantial federal interest in prosecution: This is the broadest exception. Federal prosecutors can prosecute whenever they determines there’s a “substantial federal interest,” which they defines subjectively. Organized crime, public corruption, large-scale drug trafficking, financial fraud – all of these potentially qualifies as substantial federal interests justifying dual prosecution.

Real-World Application:

Here’s what the Petite Policy looks like in practice: You gets convicted in state court and serves you’re state sentence. You thinks you’re done. Then, years later, federal prosecutors decides that the state sentence was inadequate or that federal interests wasn’t vindicated. They obtains a federal indictment for the same conduct. You gets arrested again, prosecuted again in federal court, and sentenced to additional federal prison time on top of what you already served in state prison. The Petite Policy doesn’t stop this because federal prosecutors invoked one of the exceptions.

I seen this happens in civil rights cases repeatedly. A police officer shoots someone, gets tried in state court, and is acquitted by a local jury. Federal prosecutors then brings federal civil rights charges for the exact same shooting. The officer is convicted in federal court and sentenced to federal prison. The state acquittal doesn’t matter because federal prosecutors argued that the state prosecution was inadequate and federal civil rights interests wasn’t vindicated. Courts upholds these dual prosecutions under the dual sovereignty doctrine, and the Petite Policy doesn’t help because exceptions applies.

What you needs to understand: The Petite Policy provides minimal protection. It’s a guideline for federal prosecutors, not a right you can enforce. If federal prosecutors wants to charge you after state prosecution, they almost always can find an exception that applies. Don’t assumes that state prosecution – even if you’re acquitted or serves you’re sentence – protects you from federal charges. Dual sovereignty means the feds can come after you anytime within the statute of limitations (typically 5 years for most federal felonies), irregardless of what happened in state court.

Immigration Consequences – Federal Convictions Is Worse

If you’re not a U.S. citizen, the difference between state and federal prosecution is potentially life or death for you’re immigration status. I needs to tell you straight: federal criminal convictions is treated more harshly by immigration courts then state convictions, and certain federal convictions triggers mandatory deportation with no possibility of relief. If you has a green card, temporary visa, or any other non-citizen status, you needs to understand how forum (state vs federal) affects you’re deportation risk.

Why Federal Convictions Is Worse for Immigration:

1. Federal aggravated felonies triggers mandatory deportation: Under the Immigration and Nationality Act (INA § 237(a)(2)(A)(iii)), conviction of an “aggravated felony” makes you deportable and ineligible for most forms of relief. Many federal offenses is automatically classified as aggravated felonies: drug trafficking (21 USC § 841), firearms trafficking (18 USC § 922, § 924), fraud with loss over $10,000, certain theft offenses, violent crimes, child exploitation offenses. If you’re convicted of a federal aggravated felony, you will be deported – no discretion, no waiver, no relief.

2. Immigration courts examines the federal conviction specifically: When determining deportability, immigration judges applies the “categorical approach” – they looks at the statute of conviction, not the underlying facts. Federal criminal statutes is often drafted more broadly then state statutes, which means federal convictions is more likely to qualifies as aggravated felonies or crimes involving moral turpitude (CIMTs). A drug offense that wouldn’t be an aggravated felony under state law might be an aggravated felony under federal law because the federal statute is broader.

3. Less discretionary relief available: Even if you’re conviction doesn’t triggers mandatory deportation, federal convictions carries more weight in discretionary relief proceedings. Immigration judges has less discretion to grant cancellation of removal or other relief when the conviction is federal versus state. Federal convictions signals to immigration courts that the conduct was serious enough to warrant federal prosecution, which makes judges less sympathetic.

4. Immigration agencies ignores expungements and pardons: Some states allows expungement of criminal convictions. Federal law doesn’t (except for very limited circumstances under 18 USC § 3607 for first-time drug offenders under 21). But even if you gets a state conviction expunged, immigration authorities essentially ignores the expungement and treats you as convicted anyway based off Board of Immigration Appeals precedent. Federal convictions can’t be expunged at all, so you’re stuck with it permanently for immigration purposes.

State Convictions vs Federal Convictions for Non-Citizens:

Green card holders has discovered this the hard way: identical conduct prosecuted in state court versus federal court can means the difference between keeping you’re green card and being deported to a country you hasn’t lived in for decades. Here’s why:

• State conviction for drug possession (simple possession): Might not be an aggravated felony depending on state statute. Immigration judge has discretion to grant cancellation of removal if you demonstrates rehabilitation, family ties, and hardship. You might keeps you’re green card.
• Federal conviction for drug possession with intent to distribute (21 USC § 841): Automatically classified as aggravated felony (drug trafficking). Mandatory deportation. No discretionary relief available. You loses you’re green card, gets deported, and is barred from ever returning to the U.S. Same underlying conduct, different forum, completely different immigration outcome.

This is why non-citizens facing criminal charges needs immigration lawyers involved from day one. You’re criminal defense lawyer might not understand immigration consequences. They might negotiates a plea deal that seems favorable from a criminal law perspective but triggers mandatory deportation from an immigration perspective. I seen defendants pleads guilty to federal charges without realizing they just signed their own deportation orders, irregardless of how long they been in the U.S. or whether they has U.S. citizen children.

Critical for non-citizens: If you’re facing charges in concurrent jurisdiction (both state and federal can prosecute), you needs to fight like hell to keep the case in state court. State prosecution gives you better odds of avoiding aggravated felony classifications and preserves more discretionary relief options. Federal prosecution is a death sentence for you’re immigration status in many cases. The stakes is high enough that you needs both a federal criminal defense attorney and an immigration attorney working together on you’re case from the beginning.

Defense Strategy – Why Forum Matters and What You Can Do

If there’s one thing you should takes away from this article, it’s this: the forum – state court versus federal court – determines everything about you’re case. Conviction odds, sentence length, parole eligibility, immigration consequences, even jury composition all depends on whether you’re prosecuted in state or federal court. Understanding forum differences ain’t just academic – it’s the difference between 5 years and 20 years, between probation and mandatory prison time, between keeping you’re green card and being deported.

Why Forum Is Everything:

• Conviction rates: 95%+ federal vs 68% state. You has a much better chance of winning at trial in state court, irregardless of the strength of you’re defense.
• Sentencing severity: Federal sentences is longer, with mandatory minimums and no parole (85% served minimum). State sentences is typically shorter with parole eligibility after 25-50% served in many states.
• Immigration consequences: Federal convictions is treated more harshly by immigration courts and is more likely to trigger mandatory deportation for non-citizens.
• Resources: Federal prosecutors has FBI, DEA, and unlimited investigative resources. State prosecutors is overworked and under-resourced. This affects both the strength of the government’s case and you’re defense costs.
• Jury pool: Federal juries is drawn from broader geographic areas (entire districts) and tends to be more conviction-prone. State juries is local and might be more sympathetic depending on county demographics.

Strategic Considerations for Defendants:

1. Fight federal adoption before indictment: Once federal prosecutors adopts you’re case and the grand jury returns an indictment, it’s too late to challenge federal jurisdiction. But before the indictment, you’re lawyer can advocate with federal prosecutors to decline the case and leave it in state court. Arguments that works includes: state prosecution is adequate, no substantial federal interest, state penalties is sufficient, defendant is cooperating with state authorities. This requires early engagement with federal prosecutors – you can’t wait until after arrest.

2. Negotiate with federal prosecutors EARLY: If federal agents is investigating you (FBI, DEA, ATF knocks on you’re door or executes a search warrant), federal prosecution is likely. Don’t waits for the indictment. You’re lawyer should contacts the Assistant U.S. Attorney immediately to negotiate. Sometimes federal prosecutors agrees to let state prosecutors handle the case if defendant cooperates, pleads guilty quickly, or agrees to favorable terms. Once the federal grand jury indicts you, negotiation leverage disappears.

3. Assess dual sovereignty risk if charged in state court: Just because you’re charged in state court doesn’t mean you’re safe from federal prosecution. If you’re conduct also violates federal law, assess the risk of dual prosecution. Factors that increases risk: federal agency involvement in investigation, substantial federal interest (drug trafficking, fraud, civil rights), high-profile case, inadequate state sentence from federal prosecutors’ perspective. If dual sovereignty risk is high, you’re lawyer might negotiates with federal prosecutors preemptively to get assurance they won’t prosecute federally.

4. Immigration consequences demands federal conviction avoidance: Non-citizens should avoids federal convictions at all costs. If you has concurrent jurisdiction, fight to keeps the case in state court where penalties is more lenient and aggravated felony classifications is less likely. If you’re already facing federal charges, you’re plea negotiations must involves immigration counsel to ensure the conviction doesn’t triggers mandatory deportation.

5. Understand you’re odds before trial: Federal trial is extremely risky – 95%+ conviction rate, and defendants who goes to trial and loses receives sentences 3-5x longer then defendants who pleaded guilty. State trial is less risky but still carries conviction risk. You’re lawyer needs to give you realistic odds based off the evidence, not false hope. Many times the strategic move is negotiating the best possible plea deal rather then rolling the dice at trial, particularly in federal court.

When You Needs Federal Criminal Defense:

You needs an experienced federal criminal defense lawyer immediately if:

• Federal agents (FBI, DEA, ATF, IRS, Secret Service) is investigating you or has executed a search warrant
• You receives a target letter or grand jury subpoena from a U.S. Attorney’s Office
• You’re conduct crossed state lines or involved interstate commerce
• Federal agencies was involved in you’re arrest even if state prosecutors filed charges
• You’re facing charges that falls under concurrent jurisdiction (bank robbery, drug trafficking, fraud, firearms offenses)
• You’re a non-citizen facing any criminal charges (immigration consequences requires federal expertise)

Spodek Law Group Approach:

Todd Spodek has handled both state and federal criminal cases and understands that forum selection often determines case outcomes. Federal prosecution ain’t just “more serious” then state prosecution – it’s a completely different system with different rules, different procedures, and vastly different consequences. The strategies that works in state court doesn’t works in federal court, irregardless of how experienced you’re lawyer is with state cases.

Early intervention is critical. Once federal prosecutors decides to adopt you’re case and obtains an indictment, you’re options narrows dramatically. But before the indictment, skilled advocacy can sometimes convince federal prosecutors to decline the case and defer to state prosecution. This requires understanding federal prosecutors’ priorities, DOJ policies (Petite Policy, adoption criteria), and the specific facts that makes federal prosecution more or less attractive.

If federal charges is inevitable, aggressive federal defense is essential. Federal prosecutors has unlimited resources, but they ain’t infallible. Suppression motions (Fourth Amendment, Fifth Amendment), challenges to search warrants, witness credibility attacks, and sentencing advocacy can reduces exposure even in federal court. The difference between a 10-year sentence and a 20-year sentence in federal court is often determined by how aggressively you’re lawyer challenges enhancements, argues for departures, and presents mitigating evidence.
