The criminal court process moves an accused person through a defined sequence of stages: initial appearance and bail, a probable cause screening, arraignment and pre-trial motions, either a negotiated plea or a trial, sentencing, and appeal. The Fifth and Fourteenth Amendments require the government to follow established procedures before taking anyone’s freedom or property, and every step below flows from that principle.1Constitution Annotated. Amdt5.5.1 Overview of Due Process The prosecution carries the burden of proving guilt beyond a reasonable doubt, and the defendant is presumed innocent until that burden is met. Most people picture a jury trial when they think of criminal court, but roughly 98 percent of federal convictions come from negotiated plea agreements, not verdicts.
Initial Appearance and Bail
The first court event after an arrest is the initial appearance before a judge or magistrate. Federal rules require this to happen “without unnecessary delay,” and most jurisdictions set a hard deadline between 24 and 72 hours after arrest.2Legal Information Institute. Federal Rules of Criminal Procedure Rule 5 – Initial Appearance At the hearing, the judge tells the defendant what charges have been filed, explains the right to remain silent, and addresses the right to an attorney.
The Supreme Court held in 1963 that every person accused of a serious crime has the right to court-appointed counsel if they cannot afford one.3Justia U.S. Supreme Court. Gideon v Wainwright, 372 US 335 (1963) The Sixth Amendment guarantees that right from the moment formal proceedings begin, which includes the initial appearance itself.4Constitution Annotated. Amdt6.6.3.1 Overview of When the Right to Counsel Applies Each federal district maintains its own plan for determining who qualifies financially, so there is no single nationwide income cutoff.5United States Courts. Chapter 2, Section 210 – Representation Under the CJA
The judge also decides whether the defendant can be released while the case is pending. Bail may be set as a cash amount, or the court may allow release on personal recognizance, meaning the defendant promises to return without paying anything. The Eighth Amendment prohibits bail set higher than what is reasonably needed to ensure the defendant shows up for court.6Constitution Annotated. Amdt8.2.2 Modern Doctrine on Bail Judges weigh community ties, criminal history, the seriousness of the charges, and whether the defendant poses a danger to others. A defendant who cannot post bail or meet the release conditions stays in custody as the case moves forward.
Probable Cause: Preliminary Hearing or Grand Jury
Before a felony case can go to trial, the prosecution must show probable cause to believe the defendant committed the crime. This checkpoint screens out baseless charges early, and it takes one of two forms.
In a preliminary hearing, a judge reviews the evidence in open court. The prosecutor calls witnesses, and the defense cross-examines them. The standard is much lower than “beyond a reasonable doubt.” The judge is asking only whether the evidence would allow a reasonable person to believe a crime occurred and the defendant was involved. If yes, the case advances.
A grand jury works differently. A group of citizens meets behind closed doors to hear evidence presented only by the prosecutor. The defense does not participate. If the grand jury finds enough evidence, it returns a formal charging document called an indictment.7United States Department of Justice. Justice Manual 9-11.000 – Grand Jury The Fifth Amendment requires a federal grand jury indictment for all serious federal crimes, and about half of states use grand juries as well.
Arraignment, Discovery, and Pre-Trial Motions
Once charges are formally filed, the defendant appears for arraignment. Federal rules require the arraignment to be held in open court: the judge confirms the defendant has a copy of the charges, reads or summarizes them, and asks for a plea of guilty, not guilty, or no contest.8Legal Information Institute. Federal Rules of Criminal Procedure Rule 10 – Arraignment A no-contest plea has the same immediate effect as a guilty plea for sentencing, but it cannot be used as an admission of fault in a later civil lawsuit.
Arraignment also opens discovery. Under the federal rules, the government must share a wide range of material with the defense, including the defendant’s own statements, documents, physical evidence, and expert witness information.9Legal Information Institute. Federal Rules of Criminal Procedure Rule 16 – Discovery and Inspection On top of that, the Supreme Court held in Brady v. Maryland that prosecutors must turn over any evidence favorable to the defendant that is relevant to guilt or punishment. Suppressing it violates due process, whether or not the prosecutor acted in bad faith.10Justia U.S. Supreme Court. Brady v Maryland, 373 US 83 (1963)
The pre-trial period is also when defense attorneys file motions that can narrow or end a case. A motion to suppress asks the court to exclude evidence obtained through an illegal search or seizure, drawing on the Fourth Amendment’s exclusionary rule.11Constitution Annotated. Amdt4.7.3 Standing to Suppress Illegal Evidence A motion to dismiss argues that the charges are legally insufficient even if every fact alleged is true. Judges resolve these disputes before anyone picks a jury.
Speedy Trial Deadlines
Federal law imposes firm deadlines on the prosecution. An indictment or information must be filed within 30 days of arrest, and trial must begin within 70 days after the charges are filed or the defendant’s first court appearance, whichever comes later.12Office of the Law Revision Counsel. 18 US Code 3161 – Time Limits and Exclusions Those clocks can be paused for things like competency evaluations, interlocutory appeals, and time the defense needs to prepare, so the calendar days from arrest to trial often exceed 70. When no excludable delays apply and the government misses its deadline, the charges can be dismissed. Most states have their own speedy-trial rules, and the Sixth Amendment provides a broader constitutional right enforced through a case-by-case balancing test.
Plea Bargaining
Most criminal cases never reach a jury. Plea agreements resolve an estimated 98 percent of federal convictions and around 95 percent of state convictions. When a judge accepts a guilty plea, the court must follow specific procedures: the defendant is addressed personally in open court, informed of every right being waived (including the right to a jury trial, the right to confront witnesses, and the protection against self-incrimination), and asked to confirm the plea is voluntary.13Legal Information Institute. Federal Rules of Criminal Procedure Rule 11 – Pleas The judge must also find a factual basis for the plea before entering judgment.
Negotiations take several forms. In charge bargaining, the defendant pleads guilty to a less serious offense than the one originally charged. In sentence bargaining, the defendant pleads to the original charge in exchange for the prosecutor recommending a lighter sentence. Count bargaining involves pleading to some charges while the prosecutor drops others. Judges are not bound by the prosecutor’s sentencing recommendations and can reject plea agreements entirely if the terms seem inappropriate.
Accepting a plea deal is one of the highest-stakes decisions a defendant faces. The defendant gives up the right to trial, the right to appeal most pre-trial issues, and sometimes even the right to appeal the sentence itself. The calculus depends on the strength of the evidence, the severity of the charges, and the sentencing exposure at trial compared with what the deal offers.
The Criminal Trial
Cases that don’t settle move to trial in a structured sequence.
Jury Selection
Trial begins with voir dire, where the judge and attorneys question potential jurors to uncover biases or conflicts.14United States Courts. Juror Selection Process Attorneys can remove jurors “for cause” when a specific bias is identified, and each side gets a limited number of peremptory challenges to remove jurors without stating a reason. Peremptory challenges cannot be used to exclude jurors based on race or sex.
Presentation of Evidence
After opening statements, the prosecution presents its case first. Witnesses testify, physical evidence is introduced, and the defense cross-examines each witness. The prosecution carries the full burden of proof throughout. The defense does not have to prove anything.
Once the prosecution rests, the defense can ask the judge to enter a judgment of acquittal if the evidence so far would not allow any reasonable jury to convict. Under the federal rules, the judge must grant this motion when the evidence is “insufficient to sustain a conviction.”15Legal Information Institute. Federal Rules of Criminal Procedure Rule 29 – Motion for a Judgment of Acquittal The bar is high, but it exists as a check against prosecutions that have not produced enough evidence to warrant sending the case to a jury.
If the case continues, the defense may call its own witnesses, but it is not required to. The defendant has an absolute right not to testify, and the jury cannot hold that silence against them.16Constitution Annotated. Amdt5.4.3 General Protections Against Self-Incrimination Doctrine and Practice After both sides rest, closing arguments give each attorney a final chance to tie the evidence together. The judge then instructs the jury on the legal standards to apply.
Verdict and Hung Jury
The jury deliberates in private until it reaches a unanimous verdict. Unanimity is required for all serious criminal offenses in both federal and state courts.17Constitution Annotated. Amdt6.4.4.3 Unanimity of the Jury If the jurors cannot agree, the result is a hung jury and the judge declares a mistrial. A mistrial does not free the defendant. The prosecution can retry the case with a new jury, and double jeopardy protections do not bar a retrial after a genuine hung jury. In practice, prosecutors sometimes offer more favorable plea deals after a hung jury, or drop charges if the split ran heavily in the defendant’s favor.
Sentencing
After a guilty verdict or plea, the case moves to sentencing. Federal judges work from guidelines published by the U.S. Sentencing Commission. The guidelines use a grid: one axis represents the seriousness of the offense (43 levels), and the other tracks the defendant’s criminal history (six categories). The intersection produces a recommended range of months in prison, from zero to six at the low end up to life at the top.18United States Sentencing Commission. Annotated 2025 Chapter 5 – Sentencing Table These ranges are advisory, not mandatory, so judges can depart from them when circumstances warrant.
Fines add another dimension. Federal law caps individual felony fines at $250,000, or twice the financial gain or loss involved in the offense, whichever is greater.19Office of the Law Revision Counsel. 18 USC 3571 – Sentence of Fine A fraud case causing $5 million in losses could carry a fine of $10 million. Class A misdemeanors cap at $100,000 for individuals. State fine structures vary but follow a similar graduated approach.
Judges also weigh aggravating and mitigating factors. A leadership role in a criminal scheme, use of a weapon, or targeting of vulnerable victims can push a sentence upward. A clean record, cooperation with investigators, acceptance of responsibility, or documented mental health challenges can bring it down. Victims and their families often speak at sentencing hearings, and their statements can influence the judge’s decision.
Restitution and Supervised Release
A prison sentence or fine is rarely the whole picture. Federal courts must order restitution to victims for crimes of violence, property offenses, and fraud. Restitution covers the value of lost or damaged property, medical and therapy costs, lost income, and funeral expenses when the crime results in a death.20Office of the Law Revision Counsel. 18 US Code 3663A – Mandatory Restitution to Victims of Certain Crimes Unlike a fine paid to the government, restitution goes directly to the people harmed.
Most federal sentences also include supervised release, which begins after prison. For the most serious felonies, supervised release can last up to five years; for lower-level felonies, up to three; and for misdemeanors, up to one year.21Office of the Law Revision Counsel. 18 USC 3583 – Inclusion of a Term of Supervised Release After Imprisonment A probation officer monitors the defendant, who must follow conditions such as maintaining employment, submitting to drug testing, and avoiding contact with certain people. Violating those conditions can send the defendant back to prison.
Appeals
A convicted defendant can appeal to a higher court, but an appeal is not a second trial. The appellate court reviews the written record from the original case, looking for legal errors that may have affected the outcome. Common grounds include a judge improperly admitting or excluding evidence, giving incorrect jury instructions, or applying the wrong legal standard at sentencing. The defendant must show that an error occurred and that it was significant enough to have influenced the result. No new evidence is presented, no witnesses testify, and the appellate judges do not re-weigh the facts.
If the appellate court finds a significant error, it can reverse the conviction, order a new trial, or send the case back for resentencing. If it finds no reversible error, the conviction stands. A defendant who loses at the first level can petition a higher appellate court or, in rare cases, seek review from the U.S. Supreme Court, which accepts only a tiny fraction of the petitions it receives.
Collateral Consequences of a Conviction
The sentence a judge announces is only part of what a conviction costs. Federal and state laws impose restrictions that follow people long after they finish serving time, and many defendants do not learn about them until they are already affected.
A felony conviction triggers a federal prohibition on possessing firearms or ammunition. This applies to anyone convicted of a crime punishable by more than one year in prison, whether or not the person actually served that long.22Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts Voting rights vary by jurisdiction: some states restore them automatically after release, while others require a petition or impose a waiting period. Professional licenses for healthcare, law, education, and finance can be revoked or denied. Public housing applications, student loan eligibility, and government contracting can also be affected. These consequences apply broadly, often without regard to how much time has passed or what steps someone has taken toward rehabilitation.
Understanding these downstream effects matters when deciding whether to accept a plea deal or go to trial. A conviction for what looks like a relatively minor offense can quietly close doors to employment and civic participation for years, sometimes permanently. Defense attorneys have a constitutional duty to advise clients about immigration consequences of a guilty plea, and courts increasingly expect similar warnings about other major collateral effects before accepting a plea.
