Sixth Amendment

Modern doctrine (Annotated Constitution, Amdt6.1-6.6.3.3)

This Amendment applies in criminal prosecutions — actions defined by Congress as crimes with penalties attached — but not to civil penalty actions, deportation proceedings, or post-conviction collateral relief; criminal contempt, once excluded, is now treated as a criminal prosecution for the Amendment's purposes. Though its terms bind only federal courts, the Supreme Court has come to protect all its guarantees against state abridgment through the Fourteenth Amendment Due Process Clause.

Speedy Trial Clause. The right protects against undue prosecutorial delay through the four-factor Barker v. Wingo balancing test (length of delay, reason for delay, assertion of the right, prejudice), attaching at arrest or formal charge (United States v. Marion) and detaching at conviction (Betterman v. Montana). Doggett v. United States holds sufficiently long, government-caused delay can support a presumption of prejudice without particularized proof, and Klopfer v. North Carolina both incorporates the right against the states and bars indefinitely deferring filed charges. A proven violation requires dismissal with prejudice.

Public Trial Clause. Incorporated against the states in In re Oliver, the right extends to suppression hearings and voir dire, not only the trial itself, under the four-part closure test from Waller v. Georgia — an overriding interest, closure no broader than necessary, consideration of alternatives, and adequate findings — later applied to jury selection in Presley v. Georgia. The public itself holds a separate, First Amendment-based right to attend, established in Richmond Newspapers, Inc. v. Virginia. Application to summary criminal contempt proceedings remains unsettled between In re Oliver and Levine v. United States (1960). A preserved violation is structural error, remediable without a showing of prejudice.

Jury Trial Clause (Amdt6.4.1-6.4.6.2). The Constitution guarantees criminal jury trial both here and in Art. III sec. 2 cl. 3, analyzed primarily under the Sixth Amendment; the right applies to both federal and state prosecutions by incorporation (see Duncan v. Louisiana). A defendant may waive it for a bench trial with express, intelligent consent plus the consent of the court and prosecution (Patton v. United States), or waive it via a knowing and intelligent guilty plea. The right does not reach petty offenses (see Petty Offense Doctrine), and for offenses serious enough to trigger it, any fact other than a prior conviction that increases the authorized sentence must be found by a jury beyond a reasonable doubt (see Apprendi Rule). The jury itself must have at least six members and, since Ramos v. Louisiana (2020) overruled Apodaca v. Oregon, must reach a unanimous verdict in both federal and state trials. Impartiality requires a venire representing a fair cross-section of the community (Taylor v. Louisiana) and jurors free of bias, including limits on death-qualification (Witherspoon v. Illinois) and race-based peremptory strikes (Batson v. Kentucky, an Equal Protection rather than Sixth Amendment holding).

Vicinage and Right to Local Jury (Amdt6.4.6.2). The vicinage requirement — trial by "a jury of the State and district wherein the crime shall have been committed" — has so far been applied only in federal prosecutions; the Court has not decided whether it also binds the states through the Fourteenth Amendment Due Process Clause. The "location of the commission of the criminal acts" fixes proper venue: a defendant charged only with money-laundering could not be tried where the underlying drug trafficking occurred, only where the laundering transactions themselves took place (Cabrales v. United States, 1998; United States v. Rodriguez-Moreno, 1999). Where criminal acts span multiple districts, trial may proceed in any one of them — a conspiracy may be tried where it was formed or in any district where the defendant or a co-conspirator committed an overt act (Burton v. United States, 1906; United States v. Socony-Vacuum Oil Co., 1940), and offenses consisting of interstate transportation or mailing may be tried in any district the forbidden material passes through, subject to congressional narrowing by statute (Armour Packing Co. v. United States, 1908; United States v. Johnson, 1944). A defendant has no Sixth Amendment right to a preliminary hearing before removal to the district where the offense is alleged to have occurred (United States ex rel. Hughes v. Gault, 1926), and reassigning a judge from one district to another does not itself violate vicinage by creating an undefined new judicial district (Lamar v. United States, 1916). For federal offenses committed outside any state, Congress alone may designate the place of trial, even retroactively (Jones v. United States, 1890; Cook v. United States, 1891). As with most Sixth Amendment violations, a vicinage defect is remedied by retrial before a proper jury rather than by barring retrial outright — Smith v. United States (2023) holds the Double Jeopardy Clause does not bar retrial after a conviction is vacated for improper venue or vicinage, because such a defect, unlike an acquittal, is unrelated to factual guilt or innocence.

Notice of Accusation (Amdt6.4.7). The right to be "informed of the nature and cause of the accusation" guarantees a defendant "adequate notice of the charges against [them]" — specific enough to prepare a defense and to protect against a later prosecution for the same offense (Lopez v. Smith, 574 U.S. 1, 5-6 (2014)). The Court has not gone beyond that "general proposition" to fix a specific rule, though it applied the principle to strike a conviction where the government failed to identify the subject matter of a congressional investigation a witness was charged with obstructing (Russell v. United States, 369 U.S. 749, 766-68 (1962)). The right applies to the states through the Fourteenth Amendment Due Process Clause.

Confrontation Clause. The right to be "confronted with the witnesses against him," incorporated against the states in Pointer v. Texas (1965), was governed for decades by a reliability inquiry (California v. Green, Ohio v. Roberts) before Crawford v. Washington (2004) replaced it with a categorical rule keyed to whether a statement is testimonial — testimonial statements may be admitted only if the declarant is available for cross-examination, or was unavailable but previously cross-examined. Davis v. Washington supplies the primary-purpose test separating non-testimonial statements made during an ongoing emergency from testimonial ones; Melendez-Diaz v. Massachusetts extends the standard to forensic lab certifications; and Giles v. California confirms dying declarations and forfeiture by wrongdoing as the only exceptions "established at the time of the founding."

Compulsory Process Clause (Amdt6.5.4). The right "to have compulsory process for obtaining witnesses in his favor," incorporated against the states and given its founding modern statement in Washington v. Texas (1967), guarantees the "right to present a defense" on no lesser footing than the confrontation right, subject to limits for willful discovery violations and a materiality showing where a witness becomes unavailable through no fault of the state.

Right to Counsel Clause, Right to Choose Counsel, and Effective Assistance of Counsel. The right to "the Assistance of Counsel" began as a narrow due-process holding for capital defendants unable to mount their own defense (Powell v. Alabama, 1932), became an absolute rule in federal court (Johnson v. Zerbst, 1938), and was extended to the states in full by Gideon v. Wainwright (1963), overruling Betts v. Brady's case-by-case approach. The right attaches only once adversary judicial proceedings begin (Kirby v. Illinois) and applies only to critical stages, including post-indictment interrogation in counsel's absence (Massiah v. United States, 1964), postindictment lineups (United States v. Wade, Gilbert v. California, both 1967) but not photographic displays outside the defendant's presence (United States v. Ash, 1973), and pretrial proceedings where counsel's presence could materially affect the outcome. A defendant may choose retained counsel subject to conflict-of-interest limits (Wheat v. United States), erroneously denied only at the cost of structural, non-harmless error (United States v. Gonzalez-Lopez); may lose access to forfeitable or frozen assets for that purpose (Caplin & Drysdale v. United States, United States v. Monsanto) subject to a carve-out for untainted assets (Luis v. United States); and may waive counsel altogether to represent himself (Faretta v. California), subject to standby-counsel limits (McKaskle v. Wiggins). Once counsel exists, deficient representation violates the Clause only where counsel's performance falls below an objective standard of reasonableness and the deficiency prejudices the defense to a degree undermining confidence in the outcome (Strickland v. Washington, formalizing McMann v. Richardson's founding phrase), a standard governing advice on pleas as much as at trial, including a duty to advise on deportation risk (Padilla v. Kentucky). Court interference with counsel's trial function (Geders v. United States, Herring v. New York) and uninquired-into joint-representation conflicts (Glasser v. United States, Holloway v. Arkansas, Cuyler v. Sullivan) can independently violate the right. A narrow class of cases presumes prejudice instead of requiring its proof, where the adversarial process itself has broken down (United States v. Cronic). Separately, and outside the Strickland framework entirely, a small set of fundamental decisions — including whether to maintain innocence at trial — belongs to the accused alone; counsel who overrides the client's express wishes on such a decision commits structural error regardless of strategic reasonableness (McCoy v. Louisiana).
