A federal criminal case moves through a defined sequence of steps: investigation, grand jury indictment, initial appearance, arraignment, discovery and pretrial motions, either a plea agreement or a trial, sentencing, and appeal. The steps in the federal criminal process are governed primarily by the Federal Rules of Criminal Procedure, and each stage carries its own deadlines, decision points, and consequences. Knowing what happens at each one tells you where the leverage is, where the clock is running, and where a mistake can cost the most.
Investigation and the Grand Jury
Most federal cases begin quietly. Agents at the FBI, DEA, ATF, or another federal agency gather evidence, interview witnesses, and execute search warrants, often for months before any charge is filed. When investigators believe they have probable cause, a federal agent or prosecutor can file a criminal complaint supported by an affidavit, which allows an arrest before a formal indictment.
For most federal felonies, the Fifth Amendment requires a grand jury indictment before prosecution can go forward. Under Rule 6, a grand jury of 16 to 23 citizens meets in closed sessions to review the prosecutor’s evidence. At least 12 must vote to return a “true bill” for the indictment to stand. If the grand jury finds the evidence insufficient, it returns a “no bill.” The grand jury has broad subpoena power to compel documents and testimony, and unlike at trial, the defendant generally has no right to be present, no right to put on evidence, and the standard is only probable cause.
The Speedy Trial Act sets the first hard deadline in the process. The government must file an indictment or information within 30 days of arrest or service of a summons. Some delays, including time for pretrial motions or mental competency evaluations, are excluded, but the clock is always running.
Target Letters
Before an indictment is returned, a person under investigation sometimes receives a “target letter” from the U.S. Attorney’s Office. The letter means prosecutors consider the recipient someone against whom substantial evidence of criminal conduct exists. A target letter does not guarantee charges, but the window to negotiate or cooperate before an indictment is narrow, and it is the moment to involve a federal criminal defense lawyer.
Initial Appearance and Pretrial Release
Rule 5 requires that an arrested defendant be brought before a magistrate judge “without unnecessary delay.” At this first hearing, the judge explains the charges, confirms the right to counsel, and takes up the question of pretrial release.
Defendants who cannot afford a lawyer are entitled to court-appointed counsel under the Criminal Justice Act. The test is not strict poverty. The court looks at whether the person is “financially unable to obtain counsel” after considering the cost of living for the defendant and any dependents, the cost of securing pretrial release, and the likely cost of hiring a private attorney. Doubts about eligibility are resolved in the defendant’s favor, and law enforcement plays no role in the determination.
The Bail Reform Act of 1984 starts from a presumption of release. When the government seeks detention, the judge weighs four groups of factors under 18 U.S.C. § 3142(g):
- The nature of the offense, including whether it involves violence, terrorism, a controlled substance, a firearm, or a minor victim.
- The weight of the evidence against the defendant.
- The defendant’s personal characteristics, including community ties, employment, criminal history, substance abuse history, and whether the defendant was on probation or parole at the time of arrest.
- The danger the defendant’s release would pose to the community.
For certain serious offenses, including major drug crimes and crimes of violence, a rebuttable presumption kicks in that no combination of conditions can ensure public safety. The defendant can try to overcome it, but the starting point shifts sharply toward detention.
Arraignment
At the arraignment under Rule 10, the court formally presents the charges and the defendant enters a plea of not guilty, guilty, or nolo contendere. Most defendants plead not guilty here, even if they later plan to negotiate a plea. The judge then sets deadlines for motions and discovery.
Discovery and Pretrial Motions
The stretch between arraignment and trial is where most of the real work happens. Both sides exchange information, file motions, and shape what the case will look like.
What the Government Must Turn Over
Rule 16 requires the government, upon request, to turn over the defendant’s own written or recorded statements, the defendant’s prior criminal record, documents or physical evidence the government intends to use or that is material to the defense, and the results of scientific tests or examinations. The defense has reciprocal obligations if it plans to use certain evidence or call expert witnesses.
The Constitution adds a broader obligation. Under the Brady doctrine, prosecutors must disclose any evidence favorable to the defendant that is material to guilt or punishment, including evidence that undermines the credibility of a government witness. This duty applies whether or not the defense asks. Brady violations are a frequent basis for overturned convictions.
A third disclosure layer governs witness statements. Under the Jencks Act, 18 U.S.C. § 3500, once a government witness testifies on direct examination, the defense can demand any prior statements that witness made to the government relating to the testimony. If the government refuses, the judge must strike the testimony or declare a mistrial. The defense does not get Jencks material in advance; it arrives only after the witness takes the stand.
Pretrial Motions and the 70-Day Clock
Rule 12 governs pretrial motions. Certain challenges must be raised before trial if the basis for them is reasonably available, including defects in how the prosecution was initiated, defects in the indictment, and motions to suppress evidence. A suppression motion typically argues that agents violated the Fourth Amendment during a search or seizure. A single suppression ruling can gut the government’s case.
The Speedy Trial Act creates another deadline here. Once a not-guilty plea is entered, trial must begin within 70 days from the filing of the indictment or the defendant’s first court appearance, whichever is later. If the government misses that window without an excluded-time justification, the defense can move to dismiss.
Plea Bargaining
Between 90 and 95 percent of federal criminal cases are resolved by plea rather than trial, which makes this the most consequential stage for nearly every defendant.
Rule 11 governs the process. Before accepting a guilty plea, the judge must personally address the defendant in open court and confirm that the plea is voluntary and free of force, threats, or undisclosed promises. The judge must also make sure the defendant understands:
- The nature of each charge and the maximum penalty, including any mandatory minimum.
- The right to plead not guilty and go to trial with a jury.
- The rights being waived by pleading guilty, including the right to confront witnesses, the right against self-incrimination, and the right to present evidence.
- The court’s obligation to calculate the sentencing guidelines range.
- Any provision in the plea agreement waiving the right to appeal.
- For non-citizens, that a conviction may result in deportation.
The judge must also find a factual basis for the plea, meaning the defendant has to admit conduct that actually constitutes the charged offense. A plea hearing that skips any of these steps can be attacked later.
Rule 11(a)(2) allows a “conditional plea,” where the defendant pleads guilty but reserves the written right to appeal a specific pretrial ruling, such as the denial of a suppression motion. Both the government and the court must agree. If the appeal succeeds, the defendant can withdraw the plea.
Trial
If the case does not resolve by plea, it moves to trial in a predictable order: jury selection, opening statements, the government’s case, the defense’s case, closing arguments, jury instructions, and deliberation.
Jury Selection
Under Rule 24, the judge and attorneys question prospective jurors in a process called voir dire to seat an impartial panel of 12. Either side can challenge a juror “for cause” with a specific reason that juror cannot be fair. Each side also gets peremptory challenges, which require no reason: for felonies punishable by more than one year, the defense gets 10 and the government gets 6.
Evidence and Verdict
The government goes first, calling witnesses and introducing exhibits. The defense cross-examines every government witness. After the government rests, the defense may put on its own evidence but has no obligation to do so. The defendant has no obligation to testify, and the jury is instructed not to hold silence against the defendant.
After closing arguments, the judge instructs the jury under Rule 30 on the elements of each offense, the burden of proof, and any defenses raised. Under Rule 31, the verdict must be unanimous. If the jury cannot reach unanimity, the judge may declare a mistrial.
A defendant can waive the jury and ask for a bench trial, where the judge decides guilt alone. Under Rule 23, the waiver must be in writing, the government must consent, and the court must approve. Bench trials are uncommon in federal court.
Sentencing
Sentencing is a separate proceeding, usually held weeks or months after conviction or plea. It is more structured than most people expect.
The Presentence Investigation Report
Rule 32 requires the United States Probation Office to prepare a presentence investigation report, or PSR, before sentencing. The PSR covers criminal history, personal background, financial situation, and the facts of the offense, and it calculates a recommended range under the United States Sentencing Guidelines. Both sides can review the report and object to factual errors or disputed guideline calculations before the hearing.
How the Sentence Is Decided
At the hearing, the judge weighs the factors in 18 U.S.C. § 3553(a): the nature of the offense, the defendant’s history and characteristics, the need to deter future criminal conduct, the need to protect the public, and the goal of providing the defendant with needed training or treatment. The Sentencing Guidelines are advisory, but they are the starting point, and significant deviations have to be explained on the record. Victims have a right to be reasonably heard at sentencing under the Crime Victims’ Rights Act, 18 U.S.C. § 3771, either in writing or in person.
Safety Valve Relief From Mandatory Minimums
Certain federal drug offenses carry mandatory minimums the judge normally cannot go below. Under 18 U.S.C. § 3553(f), a judge may sentence below the mandatory minimum if the defendant meets all five of these criteria:
- The defendant has a minimal criminal history (no more than 4 criminal history points, excluding 1-point offenses, and no prior serious convictions as defined in the guidelines).
- The defendant did not use violence, threaten violence, or possess a firearm in connection with the offense.
- The offense did not result in death or serious bodily injury.
- The defendant was not a leader, organizer, or manager of others in the offense.
- The defendant truthfully disclosed to the government everything they know about the offense before sentencing.
The safety valve applies only to specific drug offenses under the Controlled Substances Act and related statutes. It does not reach other crimes carrying mandatory minimums.
Supervised Release
Federal parole was abolished for offenses committed after November 1, 1987. In its place, supervised release is a separate term of supervision that starts after the prison sentence ends. The maximum length tracks the severity of the offense: up to five years for Class A and B felonies, up to three years for Class C and D felonies, and up to one year for Class E felonies and misdemeanors. Violating conditions can send the defendant back to prison, and possession of a controlled substance or firearm while on supervised release triggers mandatory revocation.
Appeals and Post-Conviction Relief
A conviction is not necessarily the final word. Federal defendants have a right to appeal and, in narrow situations, can challenge a conviction or sentence after that appeal is over.
Direct Appeal
A defendant must file a notice of appeal within 14 days after entry of judgment. This is one of the most unforgiving deadlines in federal practice; missing it by a day can forfeit the appeal, though the district court can grant a limited extension of up to 30 days for excusable neglect or good cause. If post-trial motions for acquittal, new trial, or arrest of judgment were filed, the 14-day clock restarts from the date the court rules on the last of them.
Most appeals follow a final judgment. In rare cases, a defendant can seek an interlocutory appeal of a pretrial ruling under the collateral order doctrine, where the ruling conclusively resolves a legal issue completely separate from guilt or innocence that would be effectively unreviewable later. Denied double jeopardy motions are the most common example.
Collateral Attack Under 28 U.S.C. § 2255
Once the direct appeal is over, a federal prisoner can file a motion under 28 U.S.C. § 2255 asking the sentencing court to vacate, set aside, or correct the sentence. The grounds are narrow: the sentence violated the Constitution or federal law, the court lacked jurisdiction, the sentence exceeded the legal maximum, or the judgment is otherwise subject to collateral attack. Ineffective assistance of counsel is the most common basis.
A one-year statute of limitations applies, running from the date the conviction becomes final or from other triggering events, such as the discovery of new facts or a newly recognized constitutional right. Defendants generally get only one § 2255 motion. A second or successive motion requires prior authorization from the court of appeals, granted only on very limited grounds.
Collateral Consequences of a Federal Conviction
A federal conviction reaches well past the prison sentence, and several of its consequences are automatic.
Under 18 U.S.C. § 922(g), anyone convicted of a crime punishable by more than one year in prison is prohibited from possessing firearms or ammunition. The ban is not limited to violent offenses. Violating it is itself a federal crime. Defendants with three or more prior convictions for violent felonies or serious drug crimes face a 15-year mandatory minimum under the Armed Career Criminal Act.
Non-citizens face potential deportation, denial of citizenship, or denial of future admission to the United States. Rule 11 requires the judge to warn of this at the plea hearing, but immigration proceedings themselves are handled separately. Federal felony convictions can also mean the loss of voting rights (the rules vary by state), disqualification from certain professional licenses, and ineligibility for some federal benefits. These downstream effects often outlast the sentence itself and, for many people, matter more in daily life than the prison term did.
