A prosecutor is a legal representative of the prosecution in states with either the adversarial system, which is adopted in common law, or inquisitorial system, which is adopted in civil law. The prosecution is the legal party responsible for presenting the case in a criminal trial against the defendant, an individual accused of breaking the law. Typically, the prosecutor represents the state or the government in the case brought against the accused person.
In the legal system of the United States, a Brady disclosure consists of exculpatory or impeaching information and evidence that is material to the guilt or innocence or to the punishment of a defendant. The term comes from the 1963 U.S. Supreme Court case Brady v. Maryland, in which the Supreme Court ruled that suppression by the prosecution of evidence favorable to a defendant who has requested it violates due process.
Randall Dale Adams was an American man wrongfully convicted of murder and sentenced to death after the 1976 shooting of Dallas police officer Robert W. Wood. His conviction was overturned in 1989.
Wee Care Nursery School, located in Maplewood, New Jersey, was the subject of a day care child abuse case that was tried during the 1980s. Although Margaret Kelly Michaels was prosecuted and convicted, the decision was reversed after she spent five years in prison. An appellate court ruled that several features of the original trial had produced an unjust ruling and the conviction was reversed. The case was studied by several psychologists who were concerned about the interrogation methods used and the quality of the children's testimony in the case. This resulted in research concerning the topic of children's memory and suggestibility, resulting in new recommendations for performing interviews with child victims and witnesses.
United States v. Hubbell, 530 U.S. 27 (2000), was a United States Supreme Court case involving Webster Hubbell, who had been indicted on various tax-related charges, and mail and wire fraud charges, based on documents that the government had subpoenaed from him. The Fifth Amendment provides that no person "shall be compelled in any criminal case to be a witness against himself." The Supreme Court has, since 1976, applied the so-called "act-of-production doctrine". Under this doctrine, a person can invoke his Fifth Amendment rights against the production of documents only where the very act of producing the documents is incriminating in itself.
Shareef Cousin is an African-American man from New Orleans who was convicted of the first-degree murder of Michael Gerardi in 1996 and sentenced to death as a juvenile in Louisiana. At age 17, he became the youngest condemned convict to be put on death row in Louisiana, and one of the youngest in the United States.
Witness immunity from prosecution occurs when a prosecutor agrees not to prosecute a witness in exchange for testimony or production of other evidence.
Bronston v. United States, 409 U.S. 352 (1973), is a seminal United States Supreme Court decision strictly construing the federal perjury statute. Chief Justice Warren Burger wrote for a unanimous Court that responses to questions made under oath that relayed truthful information in and of themselves but were intended to mislead or evade the examiner could not be prosecuted. Instead, the criminal-justice system had to rely on more carefully worded follow-up questions.
The Fifth Amendment to the United States Constitution creates several constitutional rights, limiting governmental powers focusing on criminal procedures. It was ratified, along with nine other amendments, in 1791 as part of the Bill of Rights.
Melendez-Diaz v. Massachusetts, 557 U.S. 305 (2009), is a United States Supreme Court case in which the Court held that it was a violation of the Sixth Amendment right of confrontation for a prosecutor to submit a chemical drug test report without the testimony of the person who performed the test. While the court ruled that the then-common practice of submitting these reports without testimony was unconstitutional, it also held that so called "notice-and-demand" statutes are constitutional. A state would not violate the Constitution through a "notice-and-demand" statute by both putting the defendant on notice that the prosecution would submit a chemical drug test report without the testimony of the scientist and also giving the defendant sufficient time to raise an objection.
Evidence-based prosecution refers to a collection of techniques utilized by prosecutors in domestic violence cases to convict abusers without the cooperation of an alleged victim. It is widely practiced within the American legal system by specialized prosecutors and state's attorneys and relies on utilizing a variety of evidence to prove the guilt of an abuser with limited or adverse participation by the abuser's victim, or even no participation at all.
Giles v. California, 554 U.S. 353 (2008), was a case decided by the Supreme Court of the United States that held that for testimonial statements to be admissible under the forfeiture exception to hearsay, the defendant must have intended to make the witness unavailable for trial.
Giglio v. United States, 405 U.S. 150 (1972), is a United States Supreme Court case in which the Court held that the prosecution's failure to inform the jury that a witness had been promised not to be prosecuted in exchange for his testimony was a failure to fulfill the duty to present all material evidence to the jury, and constituted a violation of due process, requiring a new trial. This is the case even if the failure to disclose was a matter of negligence and not intent. The case extended the Court's holding in Brady v. Maryland, requiring such agreements to be disclosed to defense counsel. As a result of this case, the term Giglio material is sometimes used to refer to any information pertaining to deals that witnesses in a criminal case may have entered into with the government.
Connick v. Thompson, 563 U.S. 51 (2011), is a United States Supreme Court case in which the Court considered whether a prosecutor's office can be held liable for a single Brady violation by one of its members on the theory that the office provided inadequate training.
Washington v. Texas, 388 U.S. 14 (1967), is a United States Supreme Court case in which the Court decided that the Compulsory Process Clause of the Sixth Amendment to the Constitution is applicable in state courts as well as federal courts. Jackie Washington had attempted to call his co-defendant as a witness, but was blocked by Texas courts because state law prevented co-defendants from testifying for each other, under the theory that they would be likely to lie for each other on the stand.
Taylor v. Illinois, 484 U.S. 400 (1988), is a United States Supreme Court decision in which the Court held that defense witnesses can be prevented from testifying under certain circumstances, even if that hurts the defense's case. Taylor was the first case to hold that there is no absolute bar to blocking the testimony of a surprise witness, even if that is an essential witness for the defendant, a limitation of the broad right to present a defense recognized in Washington v. Texas (1967).
Pointer v. Texas, 380 U.S. 400 (1965), was a decision by the United States Supreme Court involving the application of the right of to confront accusers in state court proceedings. The Sixth Amendment in the Bill of Rights states that, in criminal prosecutions, the defendant has a right "...to be confronted with the witnesses against him; to have compulsory process for obtaining witnesses in his favor..." In this case, a person arrested in Texas for robbery was deprived of the ability to cross-examine a witness when the lower court allowed the introduction of a transcript of that witness's earlier testimony at a preliminary proceeding instead of compelling attendance by the witness at trial.
Burks v. United States, 437 U.S. 1 (1978), is a United States Supreme Court decision that clarified both the scope of the protection against double jeopardy provided by the Fifth Amendment to the United States Constitution and the limits of an appellate court's discretion to fashion a remedy under section 2106 of Title 28 to the United States Code. It established the constitutional rule that where an appellate court reverses a criminal conviction on the ground that the prosecution failed to present sufficient evidence to prove the defendant's guilt beyond a reasonable doubt, the Double Jeopardy Clause shields the defendant from a second prosecution for the same offense. Notwithstanding the power that appellate courts have under section 2106 to "remand the cause and direct the entry of such appropriate judgment, decree, or order, or require such further proceedings to be had as may be just under the circumstances," a court that reverses a conviction for insufficiency of the evidence may not allow the lower court a choice on remand between acquitting the defendant and ordering a new trial. The "only 'just' remedy" in this situation, the Court held, is to order an acquittal.
Napue v. Illinois, 360 U.S. 264 (1959), was a United States Supreme Court case in which the Court held that the knowing use of false testimony by a prosecutor in a criminal case violates the Due Process Clause of the Fourteenth Amendment to the United States Constitution, even if the testimony affects only the credibility of the witness and does not directly relate to the innocence or guilt of the defendant.
United States v. Bagley, 473 U.S. 667 (1985), was a Supreme Court of the United States case that established the standard for materiality under Brady v. Maryland.
