AcquittalIn 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.
Diplock courtDiplock courts were criminal courts in Northern Ireland for non-jury trial of specified serious crimes ("scheduled offences"). They were introduced by the Northern Ireland (Emergency Provisions) Act 1973 and used for serious and terrorism-related cases during the Troubles. The Justice and Security (Northern Ireland) Act 2007 ended the automatic use of non-jury trials for scheduled offences but they are still used in Northern Ireland upon certification by the Director of Public Prosecutions on a case-by-case basis.
Reception statuteA reception statute is a statutory law adopted as a former British colony becomes independent by which the new nation adopts, or receives, the English common law before its independence to the extent not explicitly rejected by the legislative body or constitution of the new nation. Reception statutes generally consider the English common law dating prior to independence, as well as the precedents originating from it, as the default law because of the importance of using an extensive and predictable body of law to govern the conduct of citizens and businesses in a new state.
Trial by combatTrial by combat (also wager of battle, trial by battle or judicial duel) was a method of Germanic law to settle accusations in the absence of witnesses or a confession in which two parties in dispute fought in single combat; the winner of the fight was proclaimed to be right. In essence, it was a judicially sanctioned duel. It remained in use throughout the European Middle Ages, gradually disappearing in the course of the 16th century.
Lay judgeA lay judge, sometimes called a lay assessor, is a person assisting a judge in a trial. Lay judges are used in some civil law jurisdictions. Lay judges are appointed volunteers and often require some legal instruction. However, they are not permanent officers. They attend proceedings about once a month, and often receive only nominal or "costs covered" pay. Lay judges are usually used when the country does not have juries. Lay judges may be randomly selected for a single trial (as jurors are), or politically appointed.
Trial by ordealTrial by ordeal was an ancient judicial practice by which the guilt or innocence of the accused was determined by subjecting them to a painful, or at least an unpleasant, usually dangerous experience. In medieval Europe, like trial by combat, trial by ordeal, such as cruentation, was sometimes considered a "judgement of God" (jūdicium Deī, Godes dōm): a procedure based on the premise that God would help the innocent by performing a miracle on their behalf.
Petit juryIn common law, a petit jury (or trial jury; pronounced 'pEt@t or p@'ti:t, depending on the jurisdiction) hears the evidence in a trial as presented by both the plaintiff (petitioner) and the defendant (respondent). After hearing the evidence and often jury instructions from the judge, the group retires for deliberation, to consider a verdict. The majority required for a verdict varies. In some cases it must be unanimous, while in other jurisdictions it may be a majority or supermajority.
Hung juryA 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. Hung juries usually result in the case being tried again. This situation can occur only in common law legal systems, because civil law systems either do not use juries at all or provide that the defendant is immediately acquitted if the majority or supermajority required for conviction is not reached during a single, solemn vote.
Jury nullificationJury nullification (US/UK), jury equity (UK), or a perverse verdict (UK) occurs when the jury in a criminal trial gives a not guilty verdict regardless of whether they believe 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.
Plea bargainA 'plea bargain' (also plea agreement or plea deal) is an agreement in criminal law proceedings, whereby the prosecutor provides a concession to the defendant in exchange for a plea of guilt or nolo contendere. This may mean that the defendant will plead guilty to a less serious charge, or to one of the several charges, in return for the dismissal of other charges; or it may mean that the defendant will plead guilty to the original criminal charge in return for a more lenient sentence.
