The right to silence is a legal principle which guarantees any individual the right to refuse to answer questions from law enforcement officers or court officials. It is a legal right recognized, explicitly or by convention, in many of the world's legal systems.
The right covers a number of issues centered on the right of the accused or the defendant to refuse to comment or provide an answer when questioned, either prior to or during legal proceedings in a court of law. This can be the right to avoid self-incrimination or the right to remain silent when questioned. The right may include the provision that adverse inferences cannot be made by the judge or jury regarding the refusal by a defendant to answer questions before or during a trial, hearing or any other legal proceeding. This right constitutes only a small part of the defendant's rights as a whole.
The origin of the right to silence is attributed to Sir Edward Coke's challenge to the ecclesiastical courts and their ex officio oath. In the late 17th century, it became established in the law of England as a reaction to the excesses of the royal inquisitions in these courts. In the United States, informing suspects of their right to remain silent and of the consequences for giving up that right forms a key part of the Miranda warning.
History
Neither the reasons nor the history behind the right to silence are entirely clear. The Latin brocard nemo tenetur se ipsum accusare ('no man is bound to accuse himself') became a rallying cry for religious and political dissidents who were prosecuted in the Star Chamber and High Commission of 16th-century England. People coming before these tribunals were forced to make the ex officio oath by which they swore to truthfully answer the questions to be put before them without knowing what they were being accused of. This created what has been termed the cruel trilemma whereby these accused were forced to choose between committing the mortal sin of perjury (if they lied under oath to protect themselves), harsh punishment for contempt of court (if they refused to answer), or betraying their "natural" duty of self-preservation (if they told the truth to honour their oath). Sir Edward Coke's challenge to the ecclesiastical courts and their ex officio oath is seen as the origin of the right to silence. With his decision that common law courts could issue writs of prohibition against such oaths and his arguments that such oaths were contrary to the common law (as found in his Reports and Institutes), Coke "dealt the crucial blow to the oath ex officio and to the High Commission".
After the parliamentary revolutions of the late 17th century, according to some historical accounts, the right to silence became established in the law as a reaction to the excesses of the royal inquisitions in these courts. The rejection of the procedures of the Courts of Star Chamber and High Commission eventually resulted in the emergence of the principle, according to US jurist and law of evidence expert John Henry Wigmore, "that no man is bound to incriminate himself, on any charge (no matter how properly instituted), or in any Court (not merely in the ecclesiastical or Star Chamber tribunals)". It was extended during the English Restoration (from 1660 on) to include "an ordinary witness, and not merely the party charged".
However, the right to silence was not always a practical reality for all accused in the English courts for some period afterwards. With limited access to legal counsel (often depending on the social status of the accused), a shifting standard of proof, and a system generally distrustful of silent defendants, a criminal accused who remained silent was often believed to be guilty and was sentenced. Nevertheless, it remained a basic right available to the accused and has been an accepted practice over the past few centuries. In England, the practice of judicial questioning of accused persons at trial (as distinct from questioning prior to trial), did not really disappear until well into the 18th century, but by the 19th century, the accused were not allowed to give evidence on oath even if they wanted to – also said to be a reaction to the inequities of the Star Chamber and High Commission.
