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. The double jeopardy protection in criminal prosecutions bars only an identical prosecution for the same offence except when the defendant is a servicemember as the courts have ruled that the military courts are a separate sovereign therefore servicemembers can be held in two separate trials for the exact same charges; however, a different offence may be charged on identical evidence at a second trial. Res judicata protection is stronger – it precludes any causes of action or claims that arise from a previously litigated subject matter.
A plea bargain, also known as a plea agreement or plea deal, is a legal arrangement in criminal law where the defendant agrees to plead guilty or no contest to a charge in exchange for concessions from the prosecutor. These concessions can include a reduction in the severity of the charges, the dismissal of some charges, or a more lenient sentencing recommendation. Plea bargaining serves as a mechanism to expedite the resolution of criminal cases, allowing both the prosecution and the defense to avoid the time, expense, and uncertainty of a trial. It is a prevalent practice in the United States, where it resolves the vast majority of criminal cases, and has been adopted in various forms in other legal systems worldwide.
Criminal procedure is the adjudication process of the criminal law. While criminal procedure differs dramatically by jurisdiction, the process generally begins with a formal criminal charge with the person on trial either being free on bail or incarcerated, and results in the conviction or acquittal of the defendant. Criminal procedure can be either in form of inquisitorial or adversarial criminal procedure.
A jury is a sworn body of people (jurors) convened to hear evidence, make findings of fact, and render an impartial verdict officially submitted to them by a court, or to set a penalty or judgment. Most trial juries are "petit juries", and usually consist of twelve people. A larger jury known as a grand jury has been used to investigate potential crimes and render indictments against suspects.
Jury nullification, also known in the United Kingdom as jury equity, or a perverse verdict, is when the jury in a criminal trial gives a verdict of not guilty even though they think a defendant has broken the law. The jury's reasons may include the belief that the law itself is unjust, that the prosecutor has misapplied the law in the defendant's case, that the punishment for breaking the law is too harsh, or general frustrations with the criminal justice system. Some juries have also refused to convict due to their own prejudices in favor of the defendant. Such verdicts are possible because a jury has an absolute right to return any verdict it chooses. Nullification is not an official part of criminal procedure but is the logical consequence of two rules governing the systems in which it exists:
- Jurors cannot be punished for passing an incorrect verdict.
- In many jurisdictions, a defendant who is acquitted cannot be tried a second time for the same offense.
In common law jurisdictions, an acquittal means that the prosecution has failed to prove that the accused is guilty beyond a reasonable doubt of the charge presented. It certifies that the accused is free from the charge of an offense, as far as criminal law is concerned. The finality of an acquittal is dependent on the jurisdiction. In some countries, such as the United States, an acquittal prohibits the retrial of the accused for the same offense, even if new evidence surfaces that further implicates the accused. The effect of an acquittal on criminal proceedings is the same whether it results from a jury verdict or results from the operation of some other rule that discharges the accused. In other countries, like Australia and the UK, the prosecuting authority may appeal an acquittal similar to how a defendant may appeal a conviction — but usually only if new and compelling evidence comes to light or the accused has interfered with or intimidated a juror or witness.
A hung jury, also called a deadlocked jury, is a judicial jury that cannot agree upon a verdict after extended deliberation and is unable to reach the required unanimity or supermajority. A hung jury may result in the case being tried again.
Not proven is a verdict available to a court of law in Scotland. Under Scots law, a criminal trial may end in one of three verdicts, one of conviction ("guilty") and two of acquittal.
A miscarriage of justice occurs when an unfair outcome occurs in a criminal or civil proceeding, such as the conviction and punishment of a person for a crime they did not commit. Miscarriages are also known as wrongful convictions. Innocent people have sometimes ended up in prison for years before their conviction has eventually been overturned. They may be exonerated if new evidence comes to light or it is determined that the police or prosecutor committed some kind of misconduct at the original trial. In some jurisdictions this leads to the payment of compensation.
Beyond (a) reasonable doubt is a legal standard of proof required to validate a criminal conviction in most adversarial legal systems. It is a higher standard of proof than the standard of balance of probabilities commonly used in civil cases because the stakes are much higher in a criminal case: a person found guilty can be deprived of liberty or, in extreme cases, life, as well as suffering the collateral consequences and social stigma attached to a conviction. The prosecution is tasked with providing evidence that establishes guilt beyond a reasonable doubt in order to get a conviction; albeit prosecution may fail to complete such task, the trier-of-fact's acceptance that guilt has been proven beyond a reasonable doubt will in theory lead to conviction of the defendant. A failure for the trier-of-fact to accept that the standard of proof of guilt beyond a reasonable doubt has been met thus entitles the accused to an acquittal. This standard of proof is widely accepted in many criminal justice systems, and its origin can be traced to Blackstone's ratio, "It is better that ten guilty persons escape than that one innocent suffer."
Within the criminal justice system of Japan, there exist three basic features that characterize its operations. First, the institutions—police, government prosecutors' offices, courts, and correctional organs—maintain close and cooperative relations with each other, consulting frequently on how best to accomplish the shared goals of limiting and controlling crime. Second, citizens are encouraged to assist in maintaining public order, and they participate extensively in crime prevention campaigns, apprehension of suspects, and offender rehabilitation programs. Finally, officials who administer criminal justice are allowed considerable discretion in dealing with offenders.
The judicial system of Israel consists of secular courts and religious courts. The law courts constitute a separate and independent unit of Israel's Ministry of Justice. The system is headed by the President of the Supreme Court and the Minister of Justice.
The criminal law of Canada is under the exclusive legislative jurisdiction of the Parliament of Canada. The power to enact criminal law is derived from section 91(27) of the Constitution Act, 1867. Most criminal laws have been codified in the Criminal Code, as well as the Controlled Drugs and Substances Act, Youth Criminal Justice Act and several other peripheral statutes.
Actual innocence is a special standard of review in legal cases to prove that a charged defendant did not commit the crimes that they were accused of, which is often applied by appellate courts to prevent a miscarriage of justice.
Collateral consequences of criminal conviction are the additional civil state penalties, mandated by statute, that attach to a criminal conviction. They are not part of the direct consequences of criminal conviction, such as prison, fines, or probation. They are the further civil actions by the state that are triggered as a consequence of the conviction.
United States criminal procedure derives from several sources of law: the baseline protections of the United States Constitution; federal and state statutes; federal and state rules of criminal procedure ; and state and federal case law. Criminal procedures are distinct from civil procedures in the US.
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 Italian Code of Criminal Procedure contains the rules governing criminal procedure in every court in Italy. The Italian legal order adopted four codes since the Italian Unification. After the first two codes, in 1865 and 1913, the Fascist Government established in 1930 a new code adopting an inquisitorial system. In 1988 the Italian Republic adopted a new code, that could be considered to be somewhere in between the inquisitorial system and the adversarial system.
In law, post conviction refers to the legal process which takes place after a trial results in conviction of the defendant. After conviction, a court will proceed with sentencing the guilty party. In the American criminal justice system, once a defendant has received a guilty verdict, they can then challenge a conviction or sentence. This takes place through different legal actions, known as filing an appeal or a federal habeas corpus proceeding. The goal of these proceedings is exoneration, or proving a convicted person innocent. If lacking representation, the defendant may consult or hire an attorney to exercise his or her legal rights.
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.
