1. When a Criminal Case Falls under Federal Jurisdiction
Federal criminal jurisdiction applies when Congress has made the alleged conduct a federal offense and the government can establish any required jurisdictional element. Federal crimes may arise under Title 18, Title 21, Title 26, or other provisions of the United States Code. Agencies such as the FBI, DEA, and IRS Criminal Investigation investigate federal offenses within their respective statutory authority.
2. Federal Case Timeline from Arrest to Indictment
Some federal investigations become apparent through target letters, subpoenas, search warrants, or agent contact, while others remain undisclosed until an arrest or charging action occurs. Under DOJ policy, a target is a person whom the prosecutor or grand jury has substantial evidence linking to a crime and whom the prosecutor considers a putative defendant. A target letter can advise that person of target status, but federal law does not require such a letter in every investigation.
Sequential Stages in Federal Prosecution
- Initial Appearance: After an arrest, the defendant appears before a federal magistrate judge and is advised of the charges and applicable rights, while release or detention may also be addressed.
- Preliminary Hearing or Grand Jury Action: Rule 5.1 generally provides for a preliminary hearing in qualifying cases unless an exception applies, including waiver, indictment, or the filing of an information authorized by the rule.
- Indictment or Information: A grand jury may return an indictment upon finding probable cause, while a felony information may be used when indictment is lawfully waived under Rule 7(b).
- Arraignment: Under Rule 10, the defendant is informed of the indictment or information and called upon to enter a plea.

3. Constitutional Rules during Federal Agent Contact
Federal agents may request interviews before or after formal charges exist. The Fifth Amendment protects against compelled self-incrimination, while Miranda safeguards apply to custodial interrogation; the Sixth Amendment right to counsel attaches after formal adversarial proceedings begin. During a voluntary, non-custodial interview, a person generally may decline to answer questions or end the conversation.
Under 18 U.S.C. § 1001, knowingly and willfully making a materially false statement in a matter within federal jurisdiction can carry up to five years in prison, with higher limits in specified cases. False statements can create separate criminal exposure when the statutory requirements, including knowledge, willfulness, and materiality, are satisfied. Declining to participate in a voluntary interview is legally different from knowingly providing materially false information.
4. Federal Discovery under Rule 16, Brady, and Giglio
Federal pre-trial discovery follows several rules and constitutional requirements governing disclosure. Rule 16 of the Federal Rules of Criminal Procedure and separate disclosure duties address different categories of evidence. The timing and scope of disclosure therefore depend on the governing rule or constitutional requirement.
Rule 16 Discovery
Rule 16 covers specified categories of defendant statements, criminal records, documents, objects, reports, and expert information when its applicable requirements are met. Its provisions govern defined categories of pre-trial disclosure rather than creating a general right to all material held by the government.
Brady, Giglio, and Jencks Disclosures
Under Brady v. Maryland, prosecutors must disclose material evidence favorable to the defense regarding guilt or punishment. Under Giglio v. United States, this disclosure obligation includes material impeachment evidence concerning government witnesses. These duties operate separately from Rule 16.
Under the Jencks Act, 18 U.S.C. § 3500, qualifying statements of a government witness generally are not subject to compelled disclosure under that statute until after the witness has testified on direct examination. Separate constitutional or procedural disclosure obligations may require particular material to be disclosed earlier.
5. Plea Agreements and Federal Sentencing
Federal plea proceedings and sentencing follow separate rules even when both arise from a negotiated resolution. Rule 11 governs the acceptance of a guilty plea, while sentencing requires consideration of the applicable statutes, advisory Guidelines, and statutory sentencing factors.
Guilty Pleas under Rule 11
Rule 11 of the Federal Rules of Criminal Procedure requires the court to address matters including the defendant's understanding of the charge, rights, and consequences of the plea. Plea agreements may address guideline calculations, factual stipulations, charging terms, or appeal waivers, depending on their terms. The court must also determine that a guilty plea is voluntary and supported by an adequate factual basis.
Sentencing Guidelines and Statutory Minimums
Federal courts calculate and consider the advisory U.S. Sentencing Guidelines range before considering that range with the other sentencing factors in 18 U.S.C. § 3553(a). Guideline calculations can involve the offense level, specific offense characteristics, adjustments, acceptance of responsibility, and criminal history, while a statutory mandatory minimum may independently restrict sentencing discretion. Additional sentencing procedures are addressed in Sentencing Advocacy.
6. Federal Appeals and Section 2255 Motions
A federal conviction or sentence may be challenged through direct appellate review or, when statutory requirements are satisfied, collateral proceedings. These mechanisms serve different purposes and follow separate procedural rules.
Direct Appeals
A defendant generally must file a notice of appeal within 14 days after the triggering event specified in Federal Rule of Appellate Procedure 4(b). Appellate review can address preserved legal errors, evidentiary rulings, sentencing issues, and other matters properly presented on appeal. The procedures governing review in the U.S. Courts of Appeals are addressed further under Federal Appeals.
Section 2255 Collateral Review
A motion under 28 U.S.C. § 2255 can raise qualifying constitutional, jurisdictional, or other grounds recognized by the statute, including certain ineffective-assistance-of-counsel claims. Section 2255(f) generally imposes a one-year limitation period calculated from the latest applicable statutory triggering date. A Section 2255 motion is a collateral remedy rather than a substitute for a direct appeal.
