Overview of the U.S. Criminal Justice Process

The U.S. federal criminal justice process is the sequence of steps a case moves through after a federal crime is suspected. It runs from the first investigation by a federal agency to the final appeal. The stages are investigation, charging, arrest, initial appearance, arraignment, discovery, plea bargaining, trial, sentencing, and appeal. Most cases never reach a jury. About 97 to 98 percent of federal defendants who are convicted plead guilty rather than go to trial.

The rules come from a few sources. The Constitution sets the floor through the Fourth, Fifth, Sixth, and Eighth Amendments. The Federal Rules of Criminal Procedure govern how cases move through court. Title 18 of the United States Code defines most federal crimes and penalties. The federal system is separate from the fifty state systems. A state crime and a federal crime are charged in different courts, under different rules, by different prosecutors. This page covers the federal process only.

Overview

Federal cases are prosecuted by the Department of Justice, usually through one of the 94 United States Attorney's Offices. The judge is an Article III district judge or a magistrate judge. The defendant has a lawyer, either retained privately or, for those who cannot afford one, appointed under the Criminal Justice Act.

The process is built around the idea that the government carries the burden. The defendant is presumed innocent. To convict at trial, the prosecution must prove every element of the charge beyond a reasonable doubt. Several rights run through the whole case. A defendant has the right to counsel, the right to remain silent, the right to a speedy and public trial, and the right to confront the witnesses against him. Those rights do not disappear when a case settles by plea.

Federal felony cases run in the tens of thousands each year. State systems handle the far larger share of criminal volume, but the federal docket concentrates on offenses such as drug trafficking, immigration crimes, firearms violations, fraud, and white-collar cases.

Investigation and Charging

A federal case usually starts with an investigation. Agencies such as the FBI, DEA, ATF, IRS Criminal Investigation, and the U.S. Postal Inspection Service gather evidence. They interview witnesses, issue grand jury subpoenas, and seek search warrants from a judge. A search warrant requires probable cause and a sworn affidavit. Surveillance and undercover work are common in drug and fraud cases.

There are two main ways the government brings a federal felony charge. The first is a grand jury indictment. The Fifth Amendment requires a grand jury for any "capital, or otherwise infamous crime," which the courts read to mean any felony. A grand jury is a group of citizens who hear the prosecutor's evidence in private and decide whether there is probable cause to charge. If they find it, they return an indictment, also called a "true bill." The grand jury does not decide guilt. It only decides whether the case can go forward.

The second way is an information. A prosecutor can file an information, which is a charging document signed by the government rather than voted on by a grand jury. A defendant has to waive the right to a grand jury for a felony to proceed by information. This often happens when someone has already agreed to plead guilty.

Some cases begin with a complaint instead. A criminal complaint is a sworn statement of the facts and the alleged crime. It lets agents arrest a suspect quickly, before a grand jury has met. When the case starts on a complaint, the government still has to get an indictment or file an information within the time limits that follow.

Pretrial Process

After charges are filed, the defendant is taken into custody on a warrant or appears on a summons. An arrest in custody triggers Miranda warnings before any questioning. The defendant does not have to answer questions and has the right to a lawyer.

The first court date is the initial appearance. It happens without unnecessary delay, generally within a day or two of arrest. A magistrate judge tells the defendant the charges, explains his rights, and addresses release. Release is governed by the Bail Reform Act. The judge can release the person on his own recognizance, set conditions, or order detention. The government can move to detain someone it considers a flight risk or a danger, and the court holds a detention hearing to decide.

Next comes the arraignment. The defendant hears the indictment or information read and enters a plea. The choices are guilty, not guilty, or, with the court's consent, nolo contendere. Most defendants plead not guilty at this stage even when the case will later settle. A not-guilty plea opens the pretrial period.

During pretrial, both sides exchange information through discovery. Rule 16 sets out what the government must turn over, including the defendant's statements, his criminal record, documents, and the reports of expert witnesses. Two constitutional duties sit on top of the rule. Under Brady v. Maryland, the prosecution must disclose evidence that is favorable to the defendant. Under Giglio v. United States, it must disclose information that could be used to impeach a government witness, such as a cooperation deal.

This is also when lawyers file pretrial motions. A motion to suppress asks the judge to throw out evidence that was obtained in violation of the Fourth or Fifth Amendment. Other motions ask to dismiss counts, sever defendants, or limit what the jury can hear.

The Speedy Trial Act sets the clock. Trial generally has to start within 70 days of the indictment or the initial appearance, whichever is later, though the law allows long lists of excludable delay for motions, plea talks, and other reasons.

Plea bargaining runs through the entire pretrial period. A plea agreement is a contract between the defendant and the government. The defendant agrees to plead guilty, often to fewer counts than charged, in exchange for a recommendation or some other benefit. Some agreements include cooperation, where the defendant provides substantial assistance against others. That can lead the government to file a motion under § 5K1.1 of the Sentencing Guidelines asking the judge to reduce the sentence. Before accepting a guilty plea, the judge questions the defendant in open court to confirm the plea is knowing and voluntary and that there is a factual basis for it.

Trial and Sentencing

If the case does not settle, it goes to trial. A federal criminal jury has 12 members, and the verdict must be unanimous. A defendant can also waive the jury and have the judge decide the case in a bench trial. The defendant does not have to testify, and the jury cannot hold his silence against him.

The trial follows a set order. The prosecution gives an opening statement, then the defense may do the same. The government puts on its witnesses first, and the defense cross-examines them. The defense can then present its own case but is not required to. After closing arguments, the judge instructs the jury on the law. The jury deliberates in private. If all 12 jurors agree the government has proven guilt beyond a reasonable doubt, they convict. If they cannot agree, the result is a hung jury, and the government may retry the case.

Sentencing is a separate proceeding that comes weeks or months after a conviction or guilty plea. A probation officer prepares a presentence investigation report. The report calculates a range under the United States Sentencing Guidelines based on the offense level and the defendant's criminal history. The Guidelines are advisory, not mandatory. After United States v. Booker in 2005, the judge must consult the range but is not bound by it. The judge weighs the factors in 18 U.S.C. § 3553(a), which include the nature of the offense, the history of the defendant, deterrence, and the need to protect the public.

A federal sentence can include prison time, supervised release, fines, and restitution to victims. There is no parole in the federal system for crimes committed after November 1, 1987. A defendant serves the term imposed, reduced only by good-conduct time and earned credits.

Appeals

A convicted defendant can appeal to the United States Court of Appeals for the circuit that covers the trial court. The appeal is not a new trial. The appellate court reviews the record for legal error. It does not hear new evidence or new witnesses. Common grounds include a wrong ruling on a suppression motion, a flawed jury instruction, or a sentence that was calculated incorrectly. A notice of appeal in a criminal case usually has to be filed within 14 days of the judgment.

If the court of appeals rules against the defendant, the next step is a petition to the Supreme Court of the United States. The Supreme Court grants review through a writ of certiorari, and it accepts only a small fraction of the petitions it receives.

After the direct appeal is over, a separate path remains. Under 28 U.S.C. § 2255, a federal prisoner can file a motion to vacate the sentence, often on grounds the direct appeal could not reach, such as ineffective assistance of counsel. This is a form of habeas corpus relief and carries strict deadlines and limits. A separate provision, compassionate release under 18 U.S.C. § 3582(c)(1)(A), lets a court reduce a sentence for extraordinary and compelling reasons after the prisoner asks the Bureau of Prisons first.

Frequently Asked Questions

Q: What is the difference between an indictment and an information?

An indictment is a charge voted on by a grand jury, which the Fifth Amendment requires for federal felonies. An information is a charge filed by the prosecutor without a grand jury. A defendant has to waive the grand jury right for a felony to proceed by information, which usually happens when the defendant has agreed to plead guilty.

Q: How long does a federal criminal case take?

It varies widely. The Speedy Trial Act sets a 70-day target from indictment to trial, but the law allows long periods of excludable delay for motions and plea negotiations. In practice, many federal cases take close to a year from charge to sentencing, and complex cases take longer.

Q: Do most federal cases go to trial?

No. About 97 to 98 percent of federal defendants who are convicted plead guilty rather than go to trial. Trials are the exception in the federal system, not the rule.

Q: Is parole available in the federal system?

No. Federal parole was abolished for crimes committed after November 1, 1987. A federal prisoner serves the sentence imposed, reduced only by good-conduct time and earned credits such as those under the First Step Act.

Q: What does it mean that the Sentencing Guidelines are advisory?

Before 2005, judges had to sentence within the Guidelines range. After United States v. Booker, the Guidelines became advisory. A judge must calculate and consider the range but can sentence above or below it based on the factors in 18 U.S.C. § 3553(a).

Q: What is the difference between an appeal and a habeas motion?

A direct appeal asks a higher court to review the trial record for legal error and must be filed soon after judgment. A habeas motion under 28 U.S.C. § 2255 is a separate later challenge, often raising issues such as ineffective assistance of counsel that the direct appeal could not address.

Q: What rights does a federal defendant have?

A federal defendant is presumed innocent and has the right to counsel, the right to remain silent, the right to a speedy and public trial by jury, the right to confront witnesses, and protection against unreasonable searches and double jeopardy. The government must prove guilt beyond a reasonable doubt.
