In jurisprudence, double jeopardy is a procedural defence that prevents an accused person from being tried again on the same charges following an acquittal or conviction and in rare cases prosecutorial and/or judge misconduct in the same jurisdiction. Double jeopardy is a common concept in criminal law. In civil law, a similar concept is that of res judicata. Variation in common law countries is the peremptory plea, which may take the specific forms of autrefois acquit or autrefois convict. These doctrines appear to have originated in ancient Roman law, in the broader principle non bis in idem.
The Scottsboro Boys were nine African American teenage males accused in Alabama of raping two white women in 1931. The landmark set of legal cases from this incident dealt with racism and the right to a fair trial. The cases included a lynch mob before the suspects had been indicted, all-white juries, rushed trials, and disruptive mobs. It is commonly cited as an example of a legal injustice in the United States legal system.
Trial in absentia is a criminal proceeding in a court of law in which the person who is subject to it is not physically present at those proceedings. In absentia is Latin for "in (the) absence". Its meaning varies by jurisdiction and legal system.
United States v. Gonzalez-Lopez, 548 U.S. 140 (2006), is a United States Supreme Court ruling that the erroneous deprivation of a defendant's attorney of choice entitles him to a reversal of his conviction under the Sixth Amendment to the United States Constitution.
Estelle v. Smith, 451 U.S. 454 (1981), was a United States Supreme Court case in which the Court held that, per Miranda v. Arizona (1966), the state may not force a defendant to submit to a psychiatric examination solely for the purposes of sentencing. Any such examination violates the defendant's Fifth Amendment rights against self-incrimination as well as the Sixth Amendment right to counsel, and is therefore inadmissible at sentencing.
Barefoot v. Estelle, 463 U.S. 880 (1983), is a United States Supreme Court case. The Court ruled on the admissibility of clinical opinions given by two psychiatrists hired by the prosecution in answer to hypothetical questions regarding the defendant's future dangerousness and the likelihood that he would present a continuing threat to society in this Texas death penalty case. The American Psychiatric Association submitted an amicus curiae brief in support of the defendant's position that such testimony should be inadmissible and urging curtailment of psychiatric testimony regarding future dangerousness and a prohibition of such testimony based on hypothetical data.
The Double Jeopardy Clause of the Fifth Amendment to the United States Constitution provides: "[N]or shall any person be subject for the same offence to be twice put in jeopardy of life or limb..." The four essential protections included are prohibitions against, for the same offense:
The Compulsory Process Clause within the Sixth Amendment to the United States Constitution lets criminal case defendants attain witnesses in their favor by way of a court-ordered subpoena. The Clause is generally interpreted as letting defendants present their own case at trial, though several specific limitations have been placed by the Supreme Court of the United States since this rule began.
United States v. Dinitz, 424 U.S. 600 (1976), was a case in which the Supreme Court of the United States determined that the U.S. Const., Amend. V protection against double jeopardy did not prevent a retrial of a defendant, who had previously requested a mistrial.
Deck v. Missouri, 544 U.S. 622 (2005), was a United States Supreme Court case that dealt with the constitutionality of shackling a prisoner during the sentencing phase of a trial. In a 7–2 opinion delivered by Justice Breyer, the court held that it is against due process, a right prescribed by the 5th and 14th Amendments, to shackle a defendant in the sentencing portion of a trial unless the shackling relates to a specific defendant and certain state interests.
United States v. Valenzuela-Bernal, 458 U.S. 858 (1982), is a United States Supreme Court case that determined the constitutionality of deporting aliens who might give testimony in criminal alien smuggling prosecutions. Because deporting alien witnesses might take away a testimony that would be both “material and favorable” to the defendant, it gives rise to a potential motion from the defense to dismiss the indictment under the Compulsory Process Clause of the Sixth Amendment and the Due Process Clause of the Fifth Amendment.
Vasquez v. Hillery, 474 U.S. 254 (1986), is a United States Supreme Court case, which held that a defendant's conviction must be reversed if members of their race were systematically excluded from the grand jury that indicted them, even if they were convicted following an otherwise fair trial.
The United States Constitution contains several provisions regarding the law of criminal procedure.
Glasser v. United States, 315 U.S. 60 (1942), was a landmark decision of the US Supreme Court on two issues of constitutional criminal procedure. Glasser was the first Supreme Court decision to hold that the Assistance of Counsel Clause of the Sixth Amendment required the reversal of a criminal defendant's conviction if his lawyer's representation of him was limited by a conflict of interest.
Ham v. South Carolina, 409 U.S. 524 (1973), was a United States Supreme Court decision concerning examinations of prospective jurors during voir dire. The Court held that the trial court's failure to "have the jurors interrogated on the issue of racial bias" violated the petitioner's due process right under the Fourteenth Amendment. This right does not extend to any question of bias, but it does not preclude questions of relevant biases.
North Carolina v. Pearce, 395 U.S. 711 (1969), is a United States Supreme Court case that forbids judicial “vindictiveness” from playing a role in the increased sentence a defendant receives after a new trial. In sum, due process requires that a defendant be “free of apprehension” of judicial vindictiveness. Time served for a new conviction of the same offense must be “fully credited,” and a trial judge seeking to impose a greater sentence on retrial must affirmatively state the reasons for imposing such a sentence.
The Bahrain health worker trials were a series of legal cases in which forty-eight doctors, nurses, and dentists faced charges for their actions during the Bahraini uprising of 2011. In September 2011, twenty of the health workers were convicted by a military court of felonies including "stockpiling weapons" and "plotting to overthrow the government". The remaining twenty-eight were charged with misdemeanors and tried separately. The following month, the felony sentences were overturned, and it was announced that the defendants would be retried by a civilian court. Retrials began in March 2012, but were postponed until June 14. Convictions against nine of the defendants were quashed and reduced against another nine. The Court of Cassation upheld the sentences against the remaining nine on 1 October.
Kimmelman v. Morrison, 477 U.S. 365 (1986), was a decision of the U.S. Supreme Court that clarified the relationship of the right to effective assistance of counsel under the Sixth Amendment to other constitutional rights in criminal procedure. In this case, evidence against the defendant was probably seized illegally, violating the Fourth Amendment, but he lost the chance to argue that point due to his lawyer's ineffectiveness. The prosecution argued that the defendant's attempt to make a Sixth Amendment argument via a habeas corpus petition was really a way to sneak his Fourth Amendment argument in through the back door. The Court unanimously disagreed, and held that the Fourth Amendment issue and the Sixth Amendment issue represented different constitutional values, and had different requirements for prevailing in court, and therefore were to be treated separately by rules of procedure. Therefore, the habeas corpus petition could go forward. In its opinion, the Court also gave guidance on how to apply its decisions in Stone v. Powell and Strickland v. Washington.
Stone v. Powell, 428 U.S. 465 (1976), was decision of the Supreme Court of the United States that limited which claims of Fourth Amendment violations could be made by state prisoners in habeas corpus petitions in federal courts. Specifically, a claim that the exclusionary rule had been broken would be barred if state courts had already given it a full and fair hearing. The decision combined two cases that were argued before the Supreme Court on the same day with similar issues, one filed by Lloyd Powell and the other, titled Wolff v. Rice, filed by David Rice.
Chapman v. California, 386 U.S. 18 (1967), was a decision by the Supreme Court of the United States that a federal "harmless error" rule must apply, instead of equivalent state rules, for reviewing trials where federally-protected rights had been violated.
