A subpoena or witness summons is a writ issued by a government agency, most often a court, to compel testimony by a witness or production of evidence under a penalty for failure. There are two common types of subpoenas:
- subpoena ad testificandum orders a person to testify before the ordering authority or face punishment. The subpoena can also request the testimony to be given by phone or in person.
- subpoena duces tecum orders a person or organization to bring physical evidence before the ordering authority or face punishment. This is often used for requests to mail copies of documents to requesting party or directly to court.
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.
Attorney–client privilege or lawyer–client privilege is the common law doctrine of legal professional privilege in the United States. Attorney–client privilege is "[a] client's right to refuse to disclose and to prevent any other person from disclosing confidential communications between the client and the attorney."
A subpoena duces tecum, or subpoena for production of evidence, is a court summons ordering the recipient to appear before the court and produce documents or other tangible evidence for use at a hearing or trial. In some jurisdictions, it can also be issued by legislative bodies such as county boards of supervisors.
Physician–patient privilege is a legal concept, related to medical confidentiality, that protects communications between a patient and their doctor from being used against the patient in court. It is a part of the rules of evidence in many common law jurisdictions. Almost every jurisdiction that recognizes physician–patient privilege not to testify in court, either by statute or through case law, limits the privilege to knowledge acquired during the course of providing medical services. In some jurisdictions, conversations between a patient and physician may be privileged in both criminal and civil courts.
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.
First adopted in 1975, the Federal Rules of Evidence codify the evidence law that applies in United States federal courts. In addition, many states in the United States have either adopted the Federal Rules of Evidence, with or without local variations, or have revised their own evidence rules or codes to at least partially follow the federal rules.
In the Catholic Church, the Seal of Confession is the absolute duty of priests or anyone who happens to hear a confession not to disclose anything that they learn from penitents during the course of the Sacrament of Penance (confession). Even where the seal of confession does not strictly apply – where there is no specific serious sin confessed for the purpose of receiving absolution – priests have a serious obligation not to cause scandal by the way they speak.
The law of evidence, also known as the rules of evidence, encompasses the rules and legal principles that govern the proof of facts in a legal proceeding. These rules determine what evidence must or must not be considered by the trier of fact in reaching its decision. The trier of fact is a judge in bench trials, or the jury in any cases involving a jury. The law of evidence is also concerned with the quantum (amount), quality, and type of proof needed to prevail in litigation. The rules vary depending upon whether the venue is a criminal court, civil court, or family court, and they vary by jurisdiction.
Witness impeachment, in the law of evidence of the United States, is the process of calling into question the credibility of an individual testifying in a trial. The Federal Rules of Evidence contain the rules governing impeachment in US federal courts.
In common law, spousal privilege is a term used in the law of evidence to describe two separate privileges that apply to spouses: the spousal communications privilege and the spousal testimonial privilege.
The Rehabilitation of Offenders Act 1974 of the UK Parliament enables some criminal convictions to be ignored after a rehabilitation period. Its purpose is that people do not have a lifelong blot on their records because of a relatively minor offence in their past. The rehabilitation period is automatically determined by the sentence. After this period, if there has been no further conviction the conviction is "spent" and, with certain exceptions, need not be disclosed by the ex-offender in any context such as when applying for a job, obtaining insurance, or in civil proceedings. A conviction for the purposes of the ROA includes a conviction issued outside Great Britain and therefore foreign convictions are eligible to receive the protection of the ROA.
The clergy–penitent privilege, clergy privilege, confessional privilege, priest–penitent privilege, pastor–penitent privilege, clergyman–communicant privilege, or ecclesiastical privilege, is a rule of evidence that forbids judicial inquiry into certain communications between clergy and members of their congregation. This rule recognises certain communication as privileged and not subject to otherwise obligatory disclosure, similar to attorney–client privilege between lawyers and clients. In many jurisdictions certain communications between a member of the clergy of some or all religious faiths and a person consulting them in confidence are privileged in law. In particular, Catholics, Lutherans and Anglicans, among adherents of other Christian denominations, confess their sins to priests, who are unconditionally forbidden by Church canon law from making any disclosure, a position supported by the law of many countries, although in conflict with civil (secular) law in some jurisdictions. It is a distinct concept from that of confidentiality.
In common law jurisdictions and some civil law jurisdictions, legal professional privilege protects all communications between a professional legal adviser and his or her clients from being disclosed without the permission of the client. The privilege is that of the client and not that of the lawyer.
The doctrine of priest–penitent privilege does not appear to apply in English law. The orthodox view is that under the law of England and Wales privileged communication exists only in the context of legal advice obtained from a professional adviser. A statement of the law on priest–penitent privilege is contained in the nineteenth century case of Wheeler v. Le Marchant:
In the first place, the principle protecting confidential communications is of a very limited character. [...] There are many communications, which, though absolutely necessary because without them the ordinary business of life cannot be carried on, still are not privileged. [...] Communications made to a priest in the confessional on matters perhaps considered by the penitent to be more important than his life or his fortune, are not protected.
In Australia, legal professional privilege is a rule of law protecting communications between legal practitioners and their clients from disclosure under compulsion of court or statute. While the rule of legal professional privilege in Australia largely mirrors that of other Commonwealth jurisdictions, there are a number of notable qualifications and modifications to the privilege specific to Australia and its states, and contentious issues about the direction of the privilege.
The Buried Bodies Case, also known as the Lake Pleasant Bodies Case, is a mid-1970s upstate New York court case where defense attorneys Frank H. Armani and Francis Belge kept secret the location of the bodies of two women murdered by their client, Robert Garrow, Sr.
Trammel v. United States, 445 U.S. 40 (1980), is a United States Supreme Court case involving the spousal privilege and its application in the law of evidence. In it, the Court held that the witness-spouse alone has a privilege to refuse to testify adversely; the witness may be neither compelled to testify nor foreclosed from testifying.
The South African law of evidence forms part of the adjectival or procedural law of that country. It is based on English common law.
The Evidence Act 2006 is an Act of the Parliament of New Zealand that codifies the laws of evidence. When enacted, the Act drew together the common law and statutory provisions relating to evidence into one comprehensive scheme, replacing most of the previous evidence law on the admissibility and use of evidence in court proceedings.
