How Federal Criminal Cases Differ From State Cases
The Conviction Apparatus
The federal conviction rate exceeds ninety percent, and the number obscures more than it reveals. Most of that figure represents guilty pleas, not trial verdicts, because the federal system is constructed to ensure that charges are not filed until the evidence is already substantial. State prosecutions operate on a different sequence. A crime occurs, an arrest follows, and the prosecution assembles its case afterward, sometimes discovering along the way that the evidence is less complete than the initial report implied. Federal cases reverse that order. The investigation precedes the charge, often by months or years, and by the time a defendant receives notice, the government has already compiled what it regards as a finished record.
This distinction is not procedural trivia. It is the architecture of the entire system, and it determines nearly everything that follows: the plea rate, the sentence length, the advantage a prosecutor carries into every negotiation with defense counsel.
One observes this pattern across districts with remarkable consistency. The defendant is the last person to learn that the case exists.
The Grand Jury
In federal court, felony charges must originate with a grand jury indictment, a requirement rooted in the Fifth Amendment. The Constitution mandates that no person shall be held to answer for an infamous crime absent the concurrence of a grand jury. In practice, this requirement operates less as a safeguard than as a prosecutorial instrument.
A federal grand jury comprises sixteen to twenty three members. Twelve must concur to return an indictment. The proceedings are secret, the defendant has no right to be present, and defense counsel is not permitted in the room. The Federal Rules of Evidence do not apply. A prosecutor may present whatever testimony and documentation the prosecutor selects, in whatever order serves the prosecutor’s theory, and the grand jury sees nothing the prosecutor does not choose to reveal. Whether this arrangement constitutes a meaningful check on governmental power or merely an institutional formality with the appearance of deliberation is a question the system does not encourage one to ask.
State systems vary. Roughly half the states require grand jury indictments for felony prosecutions, while the rest permit prosecutors to proceed by filing an information, a formal charging document reviewed by a judge at a preliminary hearing. In states that use preliminary hearings, the defendant is present, defense counsel participates, and the standard (probable cause, the same standard the grand jury applies) is tested in an adversarial setting. The difference is not one of substance so much as procedure, but procedure determines whether the defendant has any opportunity to contest the charges before trial begins.
We encounter, with some regularity, clients who assume that an indictment means a grand jury has weighed the evidence and concluded that the case is strong. The impression is understandable. It is also, if we are being precise, not quite what occurred. The grand jury hears one side. The prosecutor selects the witnesses, frames the questions, and decides which documents to present. A grand jury that returns a “no bill,” a refusal to indict, is exceedingly rare in federal practice. The system is structured to produce indictments, and it does so with extraordinary reliability.
A federal defendant enters the case already behind. In a state prosecution that began with a preliminary hearing, defense counsel has had the opportunity to observe the prosecution’s witnesses under oath, to cross examine, and to test the state’s evidence before the case reaches trial. In a federal prosecution that began with a grand jury, the defense learns what the government possesses only through discovery. Federal discovery obligations are, in many jurisdictions, less expansive than their state counterparts.
Federal Investigation and Resources
Before any charge is filed, a federal investigation has often been running for months. The investigating agencies, the FBI, the DEA, the IRS Criminal Investigation division, the Bureau of Alcohol, Tobacco, Firearms and Explosives, among others, possess resources that most state and local law enforcement agencies cannot match. Wiretaps, cooperating witnesses, forensic accounting, surveillance operations that span multiple jurisdictions: these are standard instruments of federal investigation, not exceptional ones.
State investigations tend to be reactive. Something happens, law enforcement responds, and the case develops from that point forward. Federal investigations are proactive. A target may not know the investigation exists until agents execute a search warrant or a target letter arrives in the mail. By that time, the government may have recorded conversations, obtained financial records going back years, and secured testimony from cooperating witnesses who entered plea agreements of their own.
Three cases this year alone crossed our desks where the federal prosecution team included multiple Assistant United States Attorneys, a paralegal dedicated to the case, and agency support from two separate investigative bodies. State prosecutors, by contrast, manage hundreds of active cases. The practical effect on preparation time and trial readiness is what one would expect.
A federal case arrives at trial with a prosecution team that has lived inside the evidence for months, sometimes years.
Sentencing Under the Guidelines
Federal sentencing operates within a framework that has no true parallel in most state systems. The United States Sentencing Guidelines, established by the Sentencing Reform Act of 1984 and administered by the United States Sentencing Commission, provide advisory sentencing ranges calculated through a matrix of offense level and criminal history category. The guidelines account for the nature of the offense, the defendant’s role, the quantity of drugs or the amount of financial loss, the use of weapons, the number of victims, acceptance of responsibility, obstruction of justice, and whether the defendant occupied a position of trust or used a special skill in the commission of the offense.
Since United States v. Booker in 2005, the guidelines have been advisory rather than mandatory. A judge may vary from the guideline range, but must calculate that range and must explain any variance. In practice, the guidelines anchor the sentencing conversation.
State sentencing varies widely. Some states have their own guidelines. Others grant judges broad discretion within statutory ranges. Some maintain mandatory minimums for certain offenses. Generalizing is difficult, and perhaps irresponsible. The common thread is that state systems tend to afford judges more room to exercise judgment than the federal system does.
Federal mandatory minimum sentences deserve particular attention. For certain drug offenses, firearms violations, and other categories of crime, Congress has imposed sentence floors that neither the judge nor the guidelines can override absent specific statutory exceptions (such as cooperation with the government under Section 5K1.1 of the guidelines, or the safety valve provisions for certain nonviolent drug offenders). A prosecutor who can charge an offense carrying a ten year mandatory minimum holds a form of coercive authority that operates independently of the evidence itself, because the risk calculus changes when the floor beneath the sentence is immovable.
Most people who receive a target letter do not yet understand the difference between what the government can prove and what the government has chosen to charge. The distinction controls everything that follows.
I am less certain about this than the preceding paragraphs might suggest. Whether the advisory guidelines have produced a meaningful reduction in sentencing disparity is a question the Sentencing Commission’s own data complicates. Drug trafficking sentences in certain districts average several times longer than sentences for comparable conduct in others. The guidelines establish a shared framework for the conversation, though the results of that conversation vary more than the framework suggests.
And the sentences are served differently. Federal inmates do not receive parole. Under the Sentencing Reform Act, a federal defendant serves something like eighty five percent of the imposed sentence, with the possibility of good time credit reducing the term by no more than the remaining fraction. There are exceptions, though in practice they tend to confirm the pattern rather than complicate it. Most state systems offer parole eligibility considerably sooner. A state sentence of ten years may mean substantially less, depending on the jurisdiction and the parole board.
Dual Sovereignty and the Petite Policy
The Constitution permits both the federal government and a state government to prosecute the same defendant for the same conduct. In Gamble v. United States (2019), the Supreme Court reaffirmed this principle by a seven to two margin, holding that because each sovereign defines its own offenses, prosecution by both does not constitute double jeopardy under the Fifth Amendment. The logic is textual: an “offense” is a violation of a particular sovereign’s law, and two sovereigns produce two laws, which produce two offenses. Justice Ginsburg dissented, observing that the doctrine permits two governments to accomplish together what neither could accomplish alone.
The Department of Justice maintains an internal policy, known as the Petite policy, that constrains successive federal prosecutions following a state prosecution for the same acts. Under the policy, a federal prosecution in these circumstances requires the approval of a senior Department official and a finding that a compelling federal interest was not vindicated by the prior state proceeding. The policy is internal. It does not confer enforceable rights. Courts have held, consistently, that a defendant lacks standing to invoke it.
Whether the Petite policy provides meaningful protection or merely the architecture of restraint depends on whom one asks, and on how much faith one places in internal executive policies that carry no enforcement mechanism of their own.
What the Difference Means in Practice
The telephone call is almost always the same. A business owner, a professional, sometimes a family member, describes a visit from federal agents or a letter from a United States Attorney’s office, and the first question is whether this is the same as a state charge. It is not. By the time the federal government makes contact, the investigation has progressed well beyond the stage where early intervention can reshape the case in any fundamental way. But early intervention can still determine the scope of the charges, the government’s willingness to negotiate, and the range of outcomes that remain available.
Our approach in federal matters departs from the standard sequence in one respect we consider significant. Where the ordinary course is to wait for the indictment before engaging the prosecution, we initiate contact with the assigned Assistant United States Attorney during the pre-indictment phase whenever circumstances permit. The reasoning is practical:
- Before an indictment, the government’s charging decisions remain fluid.
- The offense level under the guidelines has not been fixed.
- The number of counts has not been determined.
- Mandatory minimums have not yet attached.
A conversation with the prosecution at this stage can influence what charges are brought, which in a system governed by mandatory minimums and sentencing guidelines, can matter more than any argument made at sentencing. We have observed that this window, narrow as it is, produces outcomes that the defensive posture most defendants assume by default does not.
There is a particular silence in a conference room at the end of a pre-indictment proffer, after the client has spoken and before anyone knows what the government will do with what it heard. That silence is the space where federal cases are either resolved or set on a course that the client did not choose.
Consultation is where this conversation begins. A first call costs nothing and assumes nothing; it is the beginning of a diagnosis. In a federal matter, the timing of that diagnosis determines whether options remain or have already closed.
