Composition

Serving on a jury is normally compulsory for those individuals who are qualified for jury service. Since a jury is intended to be an impartial panel capable of reaching a verdict, there are often procedures and requirements, for instance, fluent understanding of the language, or the ability to test jurors or otherwise exclude jurors who might be perceived as less than neutral or more partial to hear one side or the other. Juries are initially chosen randomly from the eligible population residing in the court's jurisdictional area (unless a change of venue

 jury discussions, and sometimes to read the verdict of the jury. Since there is always the possibility of jurors not completing the trial for health or other reasons, often one or more alternate jurors are nominated. Alternates hear the trial but do not take part in deciding the verdict unless a juror is unable to deliberate. In Connecticut, alternate jurors are dismissed before the panel of sworn jurors begin deliberation. Connecticut General Statutes 51-243(e) and 54-82h do not allow alternate jurors to be segregated from the regular sworn jurors. In civil cases in Connecticut, C.G.S. 51-243(e) declares that alternate jurors "shall be dismissed." This differs from the power given to the Court in criminal trials under C.G.S. 54-82h, permitting the Court to not dismiss the alternate jurors, and have the regular jury panel begin deliberations.

 tribes whereby a group of men of good character was used to investigate crimes and/or judge the accused. The same custom evolved into the vehmic court system in medieval Germany. In Anglo-Saxon England, juries investigated crimes. After the Norman Conquest, some parts of the country preserved juries as the means of investigating crimes. The use of ordinary members of the community to consider crimes was unusual in ancient cultures, but was nonetheless also found in ancient Greece.

The modern jury trial evolved out of this custom in the mid 12th century during the reign of Henry II
Henry II of England
Henry II ruled as King of England , Count of Anjou, Count of Maine, Duke of Normandy, Duke of Aquitaine, Duke of Gascony, Count of Nantes, Lord of Ireland and, at various times, controlled parts of Wales, Scotland and western France. Henry, the great-grandson of William the Conqueror, was the...

. Juries, usually 6 or 12 men, were an "ancient institution" in some parts of England. ("Henry II" 286) Members consisted of representatives of the basic units of local government—hundreds (an administrative sub-division of the shire, embracing several vills) and villages. Called juries of presentment, these men testified under oath to crimes committed in their neighborhood and indicted. The Assize of Clarendon

 in 1166 caused these juries to be adopted systematically throughout the country. The jury in this period was "self-informing," meaning it heard very little evidence or testimony in court. Instead, jurors were recruited from the locality of the dispute and were expected to know the facts before coming to court. The source of juror knowledge could include first-hand knowledge, investigation, and less reliable sources such as rumor and hearsay.

Between 1166 and 1179 new procedures including a division of functions between the sheriff, the jury of local men, and the royal justices ushered in the era of the English Common Law. Sheriffs prepared cases for trial and found jurors with relevant knowledge and testimony. Jurors 'found' a verdict by witnessing as to fact, even assessing and apply information from their own and community memory — little was written at this time and what was: deeds, writs, were subject to fraud. Royal justices supervised trials, answered questions as to law and announced the court's decision which was subject to appeal. Sheriffs executed the decision. These procedures enabled Henry II to delegate authority without endowing his subordinates with too much power. ("Henry II" 293)

 removed its sanction from all forms of ordeal — procedures by which suspects were 'tested' as to guilt (e.g., the ordeal of hot metal was applied to a suspected thief by pouring molten metal into his hand, if the wound healed rapidly and well, it was believed God found the suspect innocent, if not then guilty). With the ordeals banned, establishing guilt would have been problematic, had England not had forty years of judicial experience. Justices were accustomed to asking jurors of presentment about points of fact in assessing indictments; it was a short step to ask jurors if the accused was guilty as charged. ("Henry II" 358)

18th century England

In 1730, the British Parliament passed the Bill for Better Regulation of Juries. The Act stipulated that the list of all those liable for jury service was to be posted in each parish and that jury panels would be selected by lot, also known as sortition

, from these lists. Its aim was to prevent middle-class citizens from evading their responsibilities by financially putting into question the neutrality of the under-sheriff, the official entrusted with impanelling juries.

Prior to the Act, the main means of ensuring impartiality was by allowing legal challenges to the sheriff’s choices. The new provisions did not specifically aim at establishing impartiality, but had the effect of reinforcing the authority of the jury by guaranteeing impartiality at the point of selection.

The example of early 18th century England legal reform shows how civic lotteries can be used to organize the duties and responsibilities of the citizen body in relation to the state. It established the impartiality and neutrality of juries as well as reiterating the dual nature of the citizen-state relationship.

In Scotland, a jury in a criminal trial consists of 15 jurors, which is thought to be the largest in the world. In 2009 a review by the Scottish Government regarding the possibility of reduction, led to the decision to retain 15 jurors, with the Secretary for Justice stating that after extensive consultation, he had decided that Scotland had got it "uniquely right".

For juries to fulfill their role to analyze the facts of the case, there are strict rules about their use of information during the trial. Juries are often instructed to avoid learning about the case from any source other than the trial (such as from media

, or other means. Jurors themselves can also be held liable if they deliberately compromise their impartiality.

Role

The role of the jury is seemingly accurate to a finder of fact, while the judge is seen as having the sole responsibility of interpreting the appropriate law and instructing the jury accordingly. The jury will render a verdict on the defendant's guilt, or civil liability. Sometimes a jury will also make specific findings of fact in what is called a "special verdict." A verdict without specific findings of fact that includes only findings of guilt, civil liability and an overall amount of civil damages, if awarded, is called a "general verdict."

Juries are often justified because they leaven the law with community norms. Jury trial verdicts are not, however, legally binding precedents in other cases. For example, it would be possible for one jury to find that particular conduct is negligent, and another jury to find that it is not negligent, without either verdict being legally invalid, on precisely the same factual evidence. Occasionally, if jurors find the law to be invalid or unfair, they may acquit the defendant, regardless of the evidence that the defendant violated the law. This is commonly referred to as "jury nullification of law" or simply jury nullification
Jury nullification
Jury nullification occurs in a trial when a jury reaches a verdict contrary to the judge's instructions as to the law.A jury verdict contrary to the letter of the law pertains only to the particular case before it; however, if a pattern of acquittals develops in response to repeated attempts to...

. When there is no jury ("bench trial"), the judge makes rulings on both questions of law and of fact. In most continental European jurisdictions, the judges have more power in a trial and the role and powers of a jury are often restricted. Actual jury law and trial procedures differ between countries.

The collective knowledge and deliberate nature of juries are also given as reasons in their favor:

Detailed interviews with jurors after they rendered verdicts in trials involving complex expert testimony have demonstrated careful and critical analysis. The interviewed jurors clearly recognized that the experts were selected within an adversary process. They employed sensible techniques to evaluate the experts’ testimony, such as assessing the completeness and consistency of the testimony, comparing it with other evidence at the trial, and evaluating it against their own knowledge and life experience. Moreover, the research shows that in deliberations jurors combine their individual perspectives on the evidence and debate its relative merits before arriving at a verdict.


In the United States, juries are also entitled, when asked to do so by a judge in their jury instructions, to make factual findings on particular aggravating circumstances which will be used to elevate the defendant's sentence, if the defendant is convicted. This practice was required in all death penalty cases in Blakely v. Washington
Blakely v. Washington

,
expanded the requirement to all cases, holding that "any fact that increases the penalty for a crime beyond the prescribed statutory maximum must be submitted to a jury and proved beyond a reasonable doubt".

Many U.S. jurisdictions permit the seating of an advisory jury in a civil case in which there is no right to trial by jury to provide non-binding advice to the trial judge, although this procedural tool is rarely used. For example, a judge might seat an advisory jury to guide the judge in awarding non-economic damages in a case where there is no right to a jury trial, such as a personal injury suit brought against a state government.

In Canada, juries are also allowed to make suggestions for sentencing periods and at the time of sentencing, the suggestions of the jury are presented before the judge by the Crown prosecutor(s) before the sentence is handed down. A small number of U.S. jurisdictions, including Texas, give juries the right to set sentences as well as to find guilt or innocence.

However, this is not the practice in most other legal systems based on the English tradition, in which judges retain sole responsibility for deciding sentences according to law. The exception is the award of damages

 cases, although a judge is now obliged to make a recommendation to the jury as to the appropriate amount.

In legal systems based on English tradition, findings of fact by a jury and jury conclusions that could be supported by jury findings of fact when the specific factual basis for the verdict is not known, are entitled to great deference on appeal. In other legal systems, it is generally possible to reconsidered both findings of fact and findings of law made at the trial court level and evidence may be presented to appellate courts in what amounts to a trial de novo of appealled findings of fact made by the court of first instance in a case. The finality of trial court findings of fact in legal systems based on the English tradition has major impact on court procedure in these systems. This finality makes it imperative that lawyers be highly prepared for trial in the first instance in high stakes cases with jury trials based on the English tradition, because errors and misjudgments related to the presentation of evidence at trial to a jury cannot generally be corrected later on appeal. Surprises at trial are much more consequential in jury trials in systems based on the English tradition than they are in other legal systems as a result, so in these systems trial preparation to avoid any possibility of surprise is more important than it might be otherwise.

Jury nullification

Jury nullification means making a law void by jury decision, in other words "the process whereby a jury in a criminal case effectively nullifies a law by acquitting a defendant regardless of the weight of evidence against him or her."

Today in the United States, juries are instructed by the judge to follow his or her instructions concerning what is the "law", in his or her opinion, and to render a verdict solely on the evidence presented in court.

Modern American jurisprudence is generally intolerant of the practice, and a juror can be removed from a case if the judge believes that the juror is aware of the power of nullification.

Jury equity

In the United Kingdom, a similar power exists, often called "jury equity". This enables a jury to reach a decision in direct contradiction with the law if they feel the law is unjust. This can create a persuasive precedent for future cases, or render prosecutors reluctant to bring a charge – thus a jury has the power to influence the law.

 trials in any Australian State. The use of a Jury in criminal trials is generally by unanimous verdict of 12 lay members of the public.

 could be tried 'on indictment.' This interpretation has been criticised a 'mockery' of the section, rendering it useless: R v Federal Court of Bankruptcy; Ex parte Lowenstein (1939) 59 CLR 556 (Dixon and Evatt JJ dissenting).

Where a trial 'on indictment' has been prescribed, it is an essential element that it be found by a unanimous verdict of guilty by 12 lay members of the public. This requirement stems from the (historical) meaning of 'jury' at the time that the Constitution was written and is (in principle) thus an integral element of trial by jury:Cheatle v The Queen (1993) 177 CLR 541 (per curiam). Unlike States, an accused person cannot elect a Judge-only trial.

Belgium

The Belgian Constitution provides that all cases involving the most serious crimes be judged by juries. As a safeguard against libel cases, press crimes can also only be tried by jury. Racism is excluded from this safeguard.

Twelve jurors decide by majority whether the defendant is guilty or not. A tied vote results in 'not guilty'; a '7 guilty - 5 not guilty' vote is transferred to the 3 professional judges who can, by unanimity, reverse the majority to 'not guilty'. The sentence is delivered by a majority of the 12 jurors and the 3 professional judges. As a result of the Taxquet ruling the juries give nowadays the most important motives that lead them to their verdict. The procedural codification has been altered to meet the demands formulated by the European Court of Human Rights.

Although Article 86 of the Basic Law states that ‘the principle of trial by jury previously practised in Hong Kong shall be maintained’, it does not guarantee that every case is to be tried by jury. In Chiang Lily v. Secretary for Justice (2010), the Court of Final Appeal agreed that ‘there is no right to trial by jury in Hong Kong.’

India

Juries were formerly used in India up until the famous KM Nanavati v State of Maharashtra (1959), which led to the abolition of jury trials, although minor issues in rural areas are still handled by the panchayat raj system of village assemblies.

In the Nanavati case, Kawas Manekshaw Nanavati was tried for the murder of his wife Sylvia's paramour, Prem Ahuja. The incident shocked the nation, got unprecedented media coverage, and inspired several books and movies. The case was the last jury trial held in India.
The central question of the case was whether the gun went off accidentally or whether it was a premeditated murder.

In the former scenario, Nanavati would be charged under the Indian penal code, for culpable homicide, with a maximum punishment of 10 years. In the latter, he would be charged with murder, with the sentence being death or life imprisonment. Nanavati pleaded not guilty. His defence team argued it was a case of culpable homicide not amounting to murder, while the prosecution argued it was premeditated murder.

The jury in the Greater Bombay sessions court pronounced Nanavati not guilty with an 8–1 verdict. The sessions judge considered the acquittal as perverse and referred the case to the high court. The prosecution argued that the jury had been misled by the presiding judge on four crucial points. One, the onus of proving that it was an accident and not premeditated murder was on Nanavati. Two, was Sylvia's confession of the grave provocation for Nanavati, or any specific incident in Ahuja's bedroom or both. Three, the judge wrongly told the jury that the provocation can also come from a third person. And four, the jury was not instructed that Nanavati's defence had to be proved, to the extent that there is no reasonable doubt in the mind of a reasonable person. The court accepted the arguments, dismissed the jury's verdict and the case was freshly heard in the high court. Since the jury had also been influenced by media and public support for Nanavati and was also open to being misled, the Indian government abolished jury trials after the case.

The constitutional provisions regulating the Trial of Offences are set out in article 37 of the Irish Constitution. DPP v MC Nally sets out that a jury has the right to reach a not guilty verdict even in direct contradiction of the evidence. The principal statute regulating the selection, obligations and conduct of juries is the Juries Act 1976 as amended by the Civil Law (Miscellaneous Provisions) Act 2008, which scrapped the upper age limit of 70. Juries are not paid, nor do they receive travel expenses, however they do receive lunch for the days that they are serving.

"). The jury consists of 10 people, and has to reach a majority verdict consisting of seven or more of the jurors. The jury never gives a reason for its verdict, rather it simply gives a "guilty" or "non-guilty" verdict.

In a sense, the concept of being judged by one's peers exists on both the first and second tier of the Norwegian court system: In Tingretten, one judge and two lay judges preside, and in Lagmannsretten three judges and four lay judges preside (if a jury is not used). The lay judges do not hold any legal qualification, and represent the peers of the person on trial, as members of the general public. As a guarantee against any abuse of power by the educated elite, the number of lay judges always exceeds the number of appointed judges. In the Supreme Court

, legislates the right to a trial by jury, called "popular jury" as opposed to a "magistrates jury". The provision is arguably somewhat vague: "Section 125 - Citizens may engage in popular action and take part in the administration of justice through the institution of the jury, in the manner and with respect to those criminal trials as may be determined by law, as well as in customary and traditional courts."

Jury trials have been very slowly introduced in Spain and have often produced less than desirable results. One of the first cases was that of Mikel Otegi who was tried in 1997 for the murder of two police officers. After a confused trial, five jury members of a total of nine voted to acquit and the judge ordered the accused set free. This verdict shocked the nation.

 and sent for trial. In each court district where a grand jury is required, a group of 16–23 citizens holds an inquiry on criminal complaints brought by the prosecutor and decides if a trial is warranted (based on the standard that probable cause that a crime was committed exists), in which case an indictment is issued. In general, the size of juries tends to be larger if the crime alleged is more serious. If a grand jury rejects a proposed indictment it is known as a "no bill"; if they accept to endorse a proposed indictment it is known as a "true bill". Grand jury proceedings are ex parte: only the prosecutor may present evidence to the grand jury and defendants are not allowed to present mitigating evidence or even to know the testimony that was presented to the grand jury, and hearsay evidence is permitted. Grand juries vote to indict in the overwhelming majority of cases, and prosecutors are not prohibited from presenting the same case to a new grand jury if a "no bill" was returned by a previous grand jury. A typical grand jury considers a new criminal case every fifteen minutes. In some jurisdictions, in addition to indicting people for crimes, a grand jury may also issue reports on matters that they investigate apart from the criminal indictments that it produces, particularly when the grand jury investigation involves a public scandal. Historically, grand juries were sometimes used in American law to serve a purpose similar to an investigatory commission.

, and only about 2% of civil cases go to trial, with only about half of those trials being conducted before juries.

In 1898 the Supreme Court held that the jury must be composed of at least twelve persons, although this was not necessarily extended to state civil jury trials. In 1970, however, the Supreme Court held that the twelve persons requirement was a "historical accident", and upheld six-person juries in both criminal and civil cases. There is controversy over smaller juries, with proponents arguing that they are more efficient and opponents arguing that they lead to fluctuating verdicts. In later case, however, the court rejected the use of 5-person juries in criminal cases. Juries go through a selection process called voir dire

" has become popular.

Unanimous jury verdicts have been standard in Western law. This standard was upheld by the Supreme Court in 1897, but it was rejected in 1972 in two criminal cases. As of 1999 over thirty states had laws allowing less than unanimity in civil cases, but Oregon and Louisiana are the only states which have laws allowing less than unanimous jury verdicts for criminal cases. When the required number of jurors cannot agree on a verdict (a situation sometimes referred to as a hung jury

), a mistrial is declared, and the case may be retried with a newly constituted jury. The practice generally was that the jury rules only on questions of facts on guilt; setting the penalty was reserved for the judge. This has not been changed by rulings of the U.S. Supreme Court such as in Ring v. Arizona
Ring v. Arizona
Ring v. Arizona, , is a case in which the United States Supreme Court applied the rule of Apprendi v. New Jersey, , to capital sentencing schemes, holding that the Sixth Amendment requires a jury to find the aggravating factors necessary for imposing the death penalty. Ring overruled a portion of...

, , which found Arizona's practice, having the judge decide on aggravating factors making a defendant eligible for the death penalty, to be unconstitutional, and reserved that decision for the jury. However, in some states (such as Alabama or Florida), the ultimate decision on the punishment is made by the judge, and the jury gives only a non binding recommendation. The judge can impose the death penalty even if the jury recommends life without parole.

There is no set format for jury deliberations, and the jury will take a period of time to settle into discussing the evidence. Electing a foreperson is usually the first step, although for a particularly short or straightforward case, this may not happen until the delivery of the verdict. If a foreman is elected at the beginning, he or she will chair the discussions. The first step will typically be to find out the initial feeling or reaction to the case, which may be by a show of hands, or via secret ballot. The jury will then attempt to arrive at a consensus verdict. The exchanges of views caused by people whose opinions differ from the emerging consensus will air the issues involved in the case, and consequently points will often arise from the trial that were not specifically discussed during it. The result of these discussions is likely to be that one interpretation is shown to be the most reasonable, and a verdict is thus achieved.

In civil cases, a petit jury determines liability and damages based upon jury instructions provided by the judge.

In criminal cases, after it is determined that a case will proceed to trial, a separate petit jury (formed of petit jurors) is then convened to hear the trial
Trial (law)
In law, a trial is when parties to a dispute come together to present information in a tribunal, a formal setting with the authority to adjudicate claims or disputes. One form of tribunal is a court...

. In a few states and in death penalty cases, depending upon the law, a third jury or more often the same jury, will determine what the penalty should be or recommend what the penalty should be in the penalty phase. Usually, however, sentencing will be handled by the judge at a separate hearing. At a sentencing hearing, the burden of proof is now preponderance of the evidence, not proof beyond a reasonable doubt and hearsay is allowed. This practice gives the judge the power to change the finding of the jury when deciding on a sentence.

When used alone the term jury usually refers to a petit jury, rather than a grand jury.

Jury selection

Jurors are selected from a jury pool formed for a specified period of time—usually from one day to two weeks—from lists of citizens living in the jurisdiction of the court. The lists may be electoral rolls (i.e., a list of registered voters in the locale), people who have driver's licenses or other relevant data bases. When selected, being a member of a jury pool is, in principle, compulsory. Prospective jurors are sent a summons
Summons
Legally, a summons is a legal document issued by a court or by an administrative agency of government for various purposes.-Judicial summons:...

 and are obligated to appear in a specified jury pool room on a specified date.

However, jurors can be released from the pool for several reasons including illness, prior commitments that can't be abandoned without hardship, change of address to outside the court's jurisdiction, travel or employment outside the jurisdiction at the time of duty, and others. Often jurisdictions pay token amounts for jury duty and many issue stipends to cover transportation expenses for jurors. Work places cannot penalize employees who serve jury duty. Payments to jurors varies by jurisdiction.

In the United States jurors for grand juries are selected from jury pools.

Selection of jurors from a jury pool occurs when a trial is announced and juror names are randomly selected and called out by the jury pool clerk. Depending on the type of trial—whether a 6 person or 12 person jury is needed, in the United States—anywhere from 15 to 30 prospective jurors are sent to the courtroom to participate in voir dire
Voir dire
Voir dire is a phrase in law which comes from the Anglo-Norman language. In origin it refers to an oath to tell the truth , i.e., to say what is true, what is objectively accurate or subjectively honest, or both....

, pronounced vwaʁ diʁ in French, and defined as the oath to speak the truth in the examination testing competence of a juror, or in another application, a witness. Once the list of prospective jurors has assembled in the courtroom the court clerk assigns them seats in the order their names were originally drawn. At this point the judge often will ask each prospective juror to answer a list of general questions such as name, occupation, education, family relationships, time conflicts for the anticipated length of the trial. The list is usually written up and clearly visible to assist nervous prospective jurors and may include several questions uniquely pertinent to the particular trial. These questions are to familiarize the judge and attorneys with the jurors and glean biases, experiences, or relationships that could jeopardize the proper course of the trial.

After each prospective juror has answered the general slate of questions the attorneys may ask followup questions of some or all prospective jurors. Each side in the trial is allotted a certain number of challenges to remove prospective jurors from consideration. Some challenges are issued during voir dire while others are presented to the judge at the end of voir dire. The judge calls out the names of the anonymously challenged prospective jurors and those return to the pool for consideration in other trials. A jury is formed, then, of the remaining prospective jurors in the order that their names were originally chosen. Any prospective jurors not thusly impaneled return to the jury pool room.

Jury behavior

Scholarly research on jury behavior in American non-capital criminal felony trials reveals that juror outcomes appear to track the opinions of the median juror, rather than the opinions of the extreme juror on the panel, although juries were required to render unanimous verdicts in the jurisdictions studied. Thus, although juries must render unanimous verdicts, in run-of-the-mill criminal trials they behave in practice as if they were operating using a majority rules voting system.

 for determining guilt does not exist, the criminal justice system must rely on rulings handed down by juries. Even after a decision has been made, it is virtually impossible to know whether a jury has been correct or incorrect in freeing or accusing a defendant of a crime. Although establishing the effectiveness of juries is an arduous task, contemporary research has provided partial support for the proficiency of juries as decision makers.

The role of a Juror

Evidence has shown that jurors typically take their roles very seriously. According to Simon (1980), jurors approach their responsibilities as decision makers much in the same way as a court judge – with great seriousness, a lawful mind, and a concern for consistency that is evidence-based. By actively processing evidence, making inferences, using common sense and personal experiences to inform their decision-making, research has indicated that jurors are effective decision makers that seek thorough understanding, rather than passive, apathetic participants unfit to serve on a jury.

Judge-jury agreement

Evidence supporting jury effectiveness has also been illustrated in studies that investigate the parallels between judge and jury decision-making. According to Kalven and Zeisel (1966), it is not uncommon to find that the verdicts passed down by juries following a trial match the verdicts held by the appointed judges. Upon surveying judges and jurors of approximately 8000 criminal and civil trials, it was discovered that the verdicts handed down by both parties were in agreement 80% of the time. Such unpremeditated judge-jury agreement supports the notion that juries are effective decision-making bodies.

Buffering effects

Jurors, like most individuals, are not free from holding social and cognitive biases. Oftentimes people negatively judge individuals who do not adhere to established social norms (e.g., individuals who dress “freakishly”) or do not meet societal standards of success. Although these biases tend to influence jurors’ individual decisions during a trial, while working as part of a group (i.e., jury), these biases are typically controlled. Groups tend to exert buffering effects that allow jurors to disregard their initial personal biases when forming a credible group decision.
