Key facts: The Fourth, Fifth, Sixth, and Eighth Amendments set out core rights for criminal defendants, and the Fourteenth Amendment's Due Process Clause has made most of these protections binding on the states.[5]

The U.S. Constitution gives people accused of crimes a set of specific protections, found mainly in the Fourth, Fifth, Sixth, and Eighth Amendments.[1][2][3][4]The Fourteenth Amendment's Due Process Clause extends most of these federal protections to apply against state governments as well.[5]

Several amendments to the U.S. Constitution work together to protect people who are suspected of or charged with crimes, covering the stages from investigation through trial and punishment.[1][2][3][4]These protections apply throughout the criminal process step by step, from arrest through the criminal trial.

Fourth Amendment

The Fourth Amendment protects the right of people to be secure in their persons, houses, papers, and effects against unreasonable searches and seizures, and requires that warrants be supported by probable cause and describe with particularity the place to be searched and the persons or things to be seized.[1]It is the constitutional basis for rules governing search warrants, stop-and-frisk encounters, and other forms of surveillance.[1]More detail on these rules appears on the page about the Fourth Amendment: searches and seizures, and the landmark case Mapp v. Ohio (1961) addresses how illegally obtained evidence can be excluded.

Fifth Amendment

The Fifth Amendment guarantees the right to a grand jury in certain cases, forbids double jeopardy, and protects against self-incrimination, while also requiring due process of law before the government may deprive a person of life, liberty, or property.[2]The privilege against self-incrimination underlies the warnings police must give before a custodial interrogation, discussed further on the pages about Fifth Amendment rights and Miranda rights, with background in Miranda v. Arizona (1966).

Sixth Amendment

The Sixth Amendment guarantees the rights of criminal defendants to a speedy and public trial by an impartial jury, to be informed of the nature and cause of the accusation, to confront witnesses, to compel favorable witnesses to testify, and to have the assistance of counsel for a defense.[3]The right to counsel is central to public defenders and is explored in Gideon v. Wainwright (1963); more on these guarantees appears on the page about Sixth Amendment rights.

Eighth Amendment

The Eighth Amendment prohibits excessive bail, excessive fines, and cruel and unusual punishments, and is most often discussed in connection with the death penalty, but it also applies to civil and criminal forfeiture, such as when property is seized during a drug raid.[4]These limits affect decisions made during bail and pretrial release and at criminal sentencing; further detail is on the page about the Eighth Amendment: bail, fines and punishment.

Due process and incorporation

The Due Process Clause of the Fifth Amendment binds the federal government, requiring that no person be deprived of life, liberty, or property without due process of law, while the Fourteenth Amendment uses the same words to extend that obligation to the states.[5]Originally the Bill of Rights applied only against the federal government, but a series of Supreme Court decisions in the middle of the twentieth century found that the Due Process Clause incorporated most of the Bill of Rights' protections and made them applicable to the states, so that when a guarantee is incorporated, state and federal obligations become the same.[5]The Fourteenth Amendment also guarantees equal protection of the laws, a phrase that has figured in many landmark constitutional cases.[6]

Which constitutional rights protect people accused of crimes?

The Fourth Amendment protects against unreasonable searches and seizures and requires warrants based on probable cause.[1]The Fifth Amendment guarantees a grand jury in certain cases, forbids double jeopardy, protects against self-incrimination, and requires due process of law.[2]The Sixth Amendment guarantees a speedy public trial, an impartial jury, notice of charges, confrontation of witnesses, and the assistance of counsel[3], while the Eighth Amendment bars excessive bail, excessive fines, and cruel and unusual punishment.[4]

How do these rights apply to the states?

The Bill of Rights originally applied only against the federal government.[5]Through a series of twentieth-century Supreme Court decisions, the Fourteenth Amendment's Due Process Clause has incorporated most Bill of Rights protections, making them binding on state governments in the same way they bind the federal government.[5]

What does the Fourth Amendment protect against?

The Fourth Amendment protects the right of people to be secure in their persons, houses, papers, and effects against unreasonable searches and seizures, and requires warrants supported by probable cause.[1]It underlies rules on search warrants, stop-and-frisk, and surveillance.[1]

What is the privilege against self-incrimination?

The Fifth Amendment provides that no person shall be compelled in any criminal case to be a witness against himself.[2]This protection is part of what the Fifth Amendment guarantees alongside the right to a grand jury, protection against double jeopardy, and due process of law.[2]

What does the right to counsel under the Sixth Amendment cover?

The Sixth Amendment guarantees that in all criminal prosecutions the accused shall enjoy the assistance of counsel for a defense, along with a speedy and public trial by an impartial jury and the right to confront witnesses.[3]

Does the Eighth Amendment only apply to the death penalty?

No. While the Eighth Amendment is most often discussed in connection with the death penalty, it also prohibits excessive bail and excessive fines, including in cases of civil and criminal forfeiture, such as property seized during a drug raid.[4]
