A federal criminal case moves through a defined sequence of stages, and understanding the stages of a criminal case from arrest to appeal helps anyone facing charges, supporting a loved one, or simply trying to follow a case see what comes next. Those stages are: arrest and initial appearance, grand jury indictment, arraignment and bail, discovery and pretrial motions, plea negotiations or trial, sentencing, direct appeal, and post-conviction relief. The Fifth and Fourteenth Amendments require due process at every step, and the prosecution carries the burden of proving guilt beyond a reasonable doubt from start to finish.1Congress.gov. Amdt14.S1.3 Due Process Generally2Legal Information Institute. In re Winship
Arrest and Initial Appearance
A case usually begins with an arrest, either on a warrant signed by a judge or without one when an officer has probable cause. The arrested person must then be brought before a federal magistrate judge without unnecessary delay.3Office of the Law Revision Counsel. Federal Rules of Criminal Procedure Rule 5 – Initial Appearance At that first appearance, the judge confirms identity, explains the charges, and takes up whether the defendant will be released or detained pending further proceedings.
The right to counsel attaches here. Under Gideon v. Wainwright, anyone facing criminal charges who cannot afford a lawyer is entitled to one at no cost.4Justia. Gideon v. Wainwright, 372 U.S. 335 (1963) If you cannot hire an attorney, ask for appointed counsel at this initial appearance. Do not wait.
The Grand Jury and Indictment
Before a federal felony prosecution moves forward, the Fifth Amendment requires an indictment from a grand jury.5Legal Information Institute. Fifth Amendment, U.S. Constitution A grand jury is a group of citizens who review the prosecutor’s evidence in private and decide whether probable cause supports formal charges. They are not deciding guilt; they are deciding whether the government has enough to put someone through a trial.
Federal Rule of Criminal Procedure 7 requires indictment for any offense punishable by more than one year in prison, unless the defendant waives that right in open court and allows the prosecution to proceed by a document called an information.6Legal Information Institute. Federal Rules of Criminal Procedure Rule 7 – The Indictment and the Information Misdemeanors can go forward on an information without a grand jury. The grand jury requirement is a federal protection; most states use their own procedures, and many rely on preliminary hearings before a judge instead.
Arraignment and Bail
Once formal charges are filed, the defendant is arraigned. The court reads the charges or provides a written copy, confirms the defendant understands them, and takes a plea of guilty, not guilty, or no contest.7Legal Information Institute. Federal Rules of Criminal Procedure Rule 10 – Arraignment Most defendants plead not guilty at arraignment even when they expect to negotiate later. A not-guilty plea preserves every option while the defense investigates.
If the defendant does plead guilty or no contest, Rule 11 requires the judge to personally confirm the plea is voluntary and to explain the maximum penalties, any mandatory minimums, and the rights being given up.8Legal Information Institute. Federal Rules of Criminal Procedure Rule 11 – Pleas
The other issue at this stage is release. Federal judges weigh four categories of factors: the nature of the charges, the weight of the evidence, the defendant’s personal characteristics (community ties, employment, criminal history, substance abuse), and the danger release would pose.9Office of the Law Revision Counsel. 18 U.S. Code 3142 – Release or Detention of a Defendant Pending Trial The court starts from a presumption favoring release on the least restrictive conditions available. That can mean personal recognizance with no money required, a financial bond, travel limits, electronic monitoring, curfews, or a combination.10Federal Judicial Center. The Bail Reform Act of 1984 Pretrial services officers prepare risk assessments evaluating prior failures to appear and employment stability to help the judge decide.11United States Courts. Pretrial Release and Detention in the Federal Judiciary
Discovery and Pretrial Motions
After arraignment, the Speedy Trial Act starts the clock. The government generally has 30 days from arrest to indict and must bring the case to trial within 70 days after the indictment or first court appearance, whichever is later.12Office of the Law Revision Counsel. 18 U.S. Code 3161 – Time Limits and Exclusions Certain delays (like time the defense requests for preparation) don’t count against those limits, so actual timelines run longer. The statutory deadlines still prevent charges from hanging indefinitely.
During this period, both sides exchange information through discovery. Rule 16 requires the government to turn over categories of evidence on request, including the defendant’s own statements, results of physical or mental examinations, and scientific test reports.13Legal Information Institute. Federal Rules of Criminal Procedure Rule 16 – Discovery and Inspection The defense reviews police reports, lab work, and witness lists to map the case.
Separately, under Brady v. Maryland, the prosecution must hand over any evidence favorable to the defendant, whether it bears on guilt or on sentencing. The duty applies whether or not the defense requests it, and whether or not the prosecutor acted in good faith.14Justia. Brady v. Maryland, 373 U.S. 83 (1963) Brady violations are among the most common grounds for overturning convictions.
Once a government witness testifies at trial, the defense can demand any prior recorded statements that witness made on the same subject. If the prosecution refuses, the judge must strike that witness’s testimony entirely.15Office of the Law Revision Counsel. Federal Rules of Criminal Procedure Rule 26.2 – Producing a Witness’s Statement
Discovery feeds pretrial motions. The most consequential is a motion to suppress evidence obtained through an illegal search or seizure. Rule 12 requires suppression motions to be filed before trial, with the deadline set at or shortly after arraignment.16Legal Information Institute. Federal Rules of Criminal Procedure Rule 12 – Pleadings and Pretrial Motions If evidence was obtained in violation of the Fourth Amendment, the exclusionary rule keeps it out of trial.17Congress.gov. Amdt4.7.1 Exclusionary Rule and Evidence A successful suppression motion can end a case when the excluded evidence was the backbone of the prosecution.
Plea Bargaining
Roughly 95 percent of federal criminal cases end in guilty pleas rather than trials.18Bureau of Justice Assistance. Plea and Charge Bargaining Research Summary Plea bargaining comes in two main forms. In charge bargaining, the defendant pleads guilty to a less serious offense and heavier charges are dropped. In sentence bargaining, both sides agree on a recommended punishment or range for the judge to consider. The two are often combined.
Any plea must be voluntary and informed. The judge questions the defendant on the record to confirm no one coerced the plea and that the defendant understands the rights being waived, including the right to a jury trial, the right to confront witnesses, and the privilege against self-incrimination.8Legal Information Institute. Federal Rules of Criminal Procedure Rule 11 – Pleas The court has final authority to accept or reject the agreement. If the judge rejects it, the defendant can withdraw the plea and continue toward trial.
One point that catches defendants off guard: if you are not a U.S. citizen, a guilty plea to certain offenses can lead to deportation, denial of future citizenship, or permanent inadmissibility, and the judge is required to warn you about this before accepting the plea.
The Trial
The Sixth Amendment guarantees a speedy, public trial by an impartial jury in the district where the crime occurred.19Congress.gov. U.S. Constitution – Sixth Amendment Jury selection begins with voir dire, where attorneys question potential jurors to surface bias. Each side can strike jurors for cause and also has a limited number of peremptory challenges that require no stated reason, though peremptory strikes cannot be used to exclude jurors based on race or sex.
After the jury is sworn, both sides give opening statements. The prosecution presents its case first through witness testimony and physical exhibits, and the defense cross-examines each witness. When the prosecution rests, the defense can move for a judgment of acquittal under Rule 29 if the evidence is too weak to sustain a conviction on any charge.20Legal Information Institute. Federal Rules of Criminal Procedure Rule 29 – Motion for a Judgment of Acquittal Judges grant these sparingly, but they catch cases that should never have reached the jury.
If the case continues, the defense may put on its own witnesses and evidence. The defendant is never required to testify. The Fifth Amendment protects against self-incrimination, the prosecution cannot comment on the choice to stay silent, and the jury cannot hold it against the defendant. After both sides rest, closing arguments follow, and the judge instructs the jury on the law.
A guilty verdict must be unanimous. If the jurors cannot agree after extended deliberation, the judge declares a mistrial, and the government can retry the case with a new jury. An acquittal is final. The Double Jeopardy Clause bars the government from prosecuting someone twice for the same offense after a not-guilty verdict, even if new evidence surfaces later.
Sentencing
Sentencing is a separate proceeding, usually held weeks or months after a conviction or plea. Before the hearing, a probation officer prepares a presentence investigation report covering the defendant’s background, criminal history, employment, family situation, and the circumstances of the offense. Rule 32 requires this investigation in nearly every case.21Office of the Law Revision Counsel. Federal Rules of Criminal Procedure Rule 32 – Sentencing and Judgment Victims may submit impact statements describing the harm caused.
Federal judges work from the U.S. Sentencing Guidelines, which calculate a recommended range based on offense seriousness and criminal history.22United States Sentencing Commission. About the United States Sentencing Commission Since United States v. Booker, the Guidelines are advisory. Judges must calculate and consider the range but may go higher or lower based on the circumstances.23Justia. United States v. Booker, 543 U.S. 220 (2005) Factors pushing a sentence up include use of a weapon, a leadership role in a criminal organization, or a vulnerable victim. Factors pushing it down include cooperation, acceptance of responsibility, and minimal criminal history.
Before the judge announces the sentence, the defendant has a right to speak personally to the court. This is called allocution, and Rule 32 requires the judge to address the defendant directly and allow a statement in support of a lighter sentence.21Office of the Law Revision Counsel. Federal Rules of Criminal Procedure Rule 32 – Sentencing and Judgment A genuine statement of remorse can carry more weight with a judge than pages of legal argument.
A federal sentence can include prison time, fines, restitution to victims, and a term of supervised release. Supervised release is the federal counterpart to parole, with conditions that typically include regular reporting to a probation officer, travel restrictions, employment requirements, and prohibitions on firearms or association with people involved in crime.24United States Courts. Overview of Probation and Supervised Release Conditions Violating these conditions can send you back to prison for part or all of the remaining term.
Appeals
A conviction is not the end. A defendant has 14 days after sentencing to file a notice of appeal. When the government appeals, which is far less common, it has 30 days.25Legal Information Institute. Federal Rules of Appellate Procedure Rule 4 – Appeal as of Right, When Taken Miss the deadline and the right to a direct appeal is almost always lost. It is one of the most unforgiving deadlines in criminal law.
An appellate court does not retry the case or hear new witnesses. It reviews the trial record, reads briefs from both sides, and sometimes hears oral argument. The question is whether the trial court made a legal error significant enough to affect the outcome. Common grounds for appeal include improper admission or exclusion of evidence, flawed jury instructions, prosecutorial misconduct, and sentences that exceed legal limits. The court can affirm the conviction, reverse it, or send the case back for a new trial or resentencing.
Post-Conviction Relief Under § 2255
Even after a direct appeal is finished, federal prisoners have one more route. Under 28 U.S.C. § 2255, a person serving a federal sentence can ask the trial 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 conviction is otherwise subject to collateral attack.26Office of the Law Revision Counsel. 28 U.S. Code 2255 – Federal Custody; Remedies on Motion Attacking Sentence
The deadline is strict. A § 2255 motion must generally be filed within one year, measured from the date the conviction becomes final (when the time for direct appeal expires or the appellate court issues its final decision). In limited situations, the clock starts later: when the government itself created an obstacle to filing, when the Supreme Court recognizes a new constitutional right that applies retroactively, or when new facts supporting the claim could not have been discovered earlier through reasonable diligence.26Office of the Law Revision Counsel. 28 U.S. Code 2255 – Federal Custody; Remedies on Motion Attacking Sentence A § 2255 motion is not a second appeal, and courts treat it as an extraordinary remedy. When it succeeds, it can produce a new trial, resentencing, or release.
