In the United States, the Miranda warning is a type of notification customarily given by police to criminal suspects in police custody advising them of their right to silence and, in effect, protection from self-incrimination; that is, their right to refuse to answer questions or provide information to law enforcement or other officials. Named for the U.S. Supreme Court's 1966 decision Miranda v. Arizona, these rights are often referred to as Miranda rights. The purpose of such notification is to preserve the admissibility of their statements made during custodial interrogation in later criminal proceedings. The idea came from law professor Yale Kamisar, who subsequently was dubbed "the father of Miranda."
A search warrant is a court order that a magistrate or judge issues to authorize law enforcement officers to conduct a search of a person, location, or vehicle for evidence of a crime and to confiscate any evidence they find. In most countries, a search warrant cannot be issued in aid of civil process.
An arrest warrant or bench warrant is a warrant issued by a judge or magistrate on behalf of the state which authorizes the arrest and detention of an individual or the search and seizure of an individual's property.
Bail is a set of pre-trial restrictions that are imposed on a suspect to ensure that they will not hamper the judicial process. Court bail may be offered to secure the conditional release of a defendant with the promise to appear in court when required. In some countries, especially the United States, bail usually implies a bail bond, a deposit of money or some form of property to the court by the suspect in return for the release from pre-trial detention. If the suspect does not return to court, the bail is forfeited and the suspect may be charged with the crime of failure to appear. If the suspect returns to make all their required appearances, bail is returned after the trial is concluded.
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.
A citizen's arrest is an arrest made by a private citizen – a person who is not acting as a sworn law-enforcement official. In common law jurisdictions, the practice dates back to medieval England and the English common law, in which sheriffs encouraged ordinary citizens to help apprehend law breakers.
False arrest, unlawful arrest or wrongful arrest is a common law tort, where a plaintiff alleges they were held in custody without probable cause, or without an order issued by a court of competent jurisdiction. Although it is possible to sue law enforcement officials for false arrest, the usual defendants in such cases are private security firms.
In criminal law, self-incrimination is the act of making a statement that exposes oneself to an accusation of criminal liability or prosecution. Self-incrimination can occur either directly or indirectly: directly, by means of interrogation where information of a self-incriminatory nature is disclosed; or indirectly, when information of a self-incriminatory nature is disclosed voluntarily without pressure from another person.
The Police and Criminal Evidence Act 1984 (PACE) is an act of Parliament which instituted a legislative framework for the powers of police officers in England and Wales to combat crime, and provided codes of practice for the exercise of those powers. Part VI of PACE required the Home Secretary to issue Codes of Practice governing police powers. The aim of PACE is to establish a balance between the powers of the police in England and Wales and the rights and freedoms of the public. Equivalent provision is made for Northern Ireland by the Police and Criminal Evidence Order 1989 (SI 1989/1341). The equivalent in Scots Law is the Criminal Procedure (Scotland) Act 1995.
A police caution is a formal alternative to prosecution in minor cases, administered by the police in England and Wales. It is commonly used to resolve cases where full prosecution is not seen as the most appropriate solution. Accepting a caution requires an admission of guilt.
A duty solicitor, duty counsel, or duty lawyer, is a solicitor whose services are available to a person either suspected of, or charged with, a criminal offence free of charge, if that person does not have access to a solicitor of their own and usually if it is judged by a means test that they cannot afford one. The system is operative in several Commonwealth countries, including the United Kingdom, Australia, New Zealand and Canada.
The right to silence in England and Wales is the protection given to a person during criminal proceedings from adverse consequences of remaining silent. It is sometimes referred to as the privilege against self-incrimination. It is used on any occasion when it is considered the person being spoken to is under suspicion of having committed one or more criminal offences and consequently thus potentially being subject to criminal proceedings.
Pre-trial detention, also known as jail, preventive detention, provisional detention, or remand, is the process of detaining a person until their trial after they have been arrested and charged with an offence. A person who is on remand is held in a prison or detention centre or held under house arrest. Varying terminology is used, but "remand" is generally used in common law jurisdictions and "preventive detention" elsewhere. However, in the United States, "remand" is rare except in official documents and "jail" is instead the main terminology. Detention before charge is commonly referred to as custody and continued detention after conviction is referred to as imprisonment.
The youth justice system in England and Wales comprises the organs and processes that are used to prosecute, convict and punish persons under 18 years of age who commit criminal offences. The principal aim of the youth justice system is to prevent offending by children and young persons.
Bail in Canada refers to the release of a person charged with a criminal offence prior to being tried in court or sentenced. The Canadian Bill of Rights and the Canadian Charter of Rights and Freedoms guarantee the right not to be denied reasonable bail without just cause. That right is implemented by the Criminal Code, which provides several ways for a person to be released prior to a court appearance. A person may be released by a peace officer or by the courts. A release by the courts is officially known as a judicial interim release. There are also a number of ways to compel a person's appearance in court without the need for an arrest and release.
The powers of the police in Scotland, as with much of Scots law, are based on mixed elements of statute law and common law.
The powers of the police in England and Wales are defined largely by statute law, with the main sources of power being the Police and Criminal Evidence Act 1984 and the Police Act 1996. This article covers the powers of police officers of territorial police forces only, but a police officer in one of the UK's special police forces can utilise extended jurisdiction powers outside of their normal jurisdiction in certain defined situations as set out in statute. In law, police powers are given to constables. All police officers in England and Wales are "constables" in law whatever their rank. Certain police powers are also available to a limited extent to police community support officers and other non warranted positions such as police civilian investigators or designated detention officers employed by some police forces even though they are not constables.
Following the common law system introduced into Hong Kong when it became a Crown colony, Hong Kong's criminal procedural law and the underlying principles are very similar to the one in the UK. Like other common law jurisdictions, Hong Kong follows the principle of presumption of innocence. This principle penetrates the whole system of Hong Kong's criminal procedure and criminal law. Viscount Sankey once described this principle as a 'golden thread'. Therefore, knowing this principle is vital for understanding the criminal procedures practised in Hong Kong.
The Code of Criminal Procedure, commonly called Criminal Procedure Code (CrPC), was the main legislation on procedure for administration of substantive criminal law in India. It was enacted in 1973 and came into force on 1 April 1974. It provides the machinery for the investigation of crime, apprehension of suspected criminals, collection of evidence, determination of guilt or innocence of the accused person and the determination of punishment of the guilty. It also deals with public nuisance, prevention of offences and maintenance of wife, child and parents.
Criminal procedure in South Africa refers to the adjudication process of that country's criminal law. It forms part of procedural or adjectival law, and describes the means by which its substantive counterpart, South African criminal law, is applied. It has its basis mainly in English law.
