Subpoena in the context of "Witnesses"

A grand jury is a jury empowered by law to conduct legal proceedings, investigate potential criminal conduct, and determine whether criminal charges should be brought. A grand jury may subpoena physical evidence or a person to testify. A grand jury is separate from the courts, which do not preside over its functioning.

Originating in England during the Middle Ages, modern examples include grand juries in the United States, and to a lesser extent, Liberia. In Japan, there are citizen Prosecutorial Review Commissions which review cases that have been dropped by the prosecution, but they are not required for an indictment like in the previous two. Grand juries perform both accusatory and investigatory functions. The investigatory functions of grand juries include obtaining and reviewing documents and other evidence, and hearing sworn testimonies of witnesses who appear before it; the accusatory function determines whether there is probable cause to believe that one or more persons committed a particular offense within the jurisdiction of a court. While most grand juries focus on criminal matters, some civil grand juries serve an independent watchdog function. Around the 18th and 19th-century in Ireland and the U.S., grand juries were occasionally formed to pass or approve public policy.

In common law, a writ is a formal written order issued by a body with administrative or judicial jurisdiction; in modern usage, this body is generally a court. Warrants, prerogative writs, subpoenas, and certiorari are common types of writs, but many forms exist and have existed.

In its earliest form, a writ was simply a written order made by the English monarch to a specified person to undertake a specified action; for example, in the feudal era, a military summons by the king to one of his tenants-in-chief to appear dressed for battle with retinue at a specific place and time. An early usage survives in the United Kingdom, Canada, Australia, and some other Commonwealth countries in a writ of election, which is a written order issued on behalf of the monarch (in Canada, by the Governor General and, in Australia, by the Governor-General for elections for the House of Representatives, or state governors for state elections) to local officials to hold a general election. Writs were used by the medieval English kings to summon people to Parliament (then consisting primarily of the House of Lords) whose advice was considered valuable or who were particularly influential, and who were thereby deemed to have been created "barons by writ".

In law, a witness is someone who, either voluntarily or under compulsion, provides testimonial evidence, either oral or written, of what they know or claim to know.

A witness might be compelled to provide testimony in court, before a grand jury, before an administrative tribunal, before a deposition officer, or in a variety of other legal proceedings. A subpoena is a legal document that commands a person to appear at a proceeding. It is used to compel the testimony of a witness in a trial. Usually, it can be issued by a judge or by the lawyer representing the plaintiff or the defendant in a civil trial or by the prosecutor or the defense attorney in a criminal proceeding, or by a government agency. In many jurisdictions, it is compulsory to comply with the subpoena and either take an oath or solemnly affirm to testify truthfully under penalty of perjury.

Legal process (sometimes simply process) is any formal notice or writ by a court obtaining jurisdiction over a person or property. Common forms of process include a summons, subpoena, mandate, and warrant. Process normally takes effect by serving it on a person, arresting a person, posting it on real property, or seizing personal property.

Alger Hiss (November 11, 1904 – November 15, 1996) was an American government official who, in 1948, was accused of spying for the Soviet Union in the 1930s. The statute of limitations had expired for espionage, but he was convicted of perjury in connection with this charge in 1950. Before the trial, Hiss was involved in the establishment of the United Nations, both as a U.S. State Department official and as a UN official. In later life, he worked as a lecturer and author.

On August 3, 1948, Whittaker Chambers, a former Communist Party USA member, testified under subpoena before the House Un-American Activities Committee (HUAC) that Hiss had secretly been a communist while in federal service. Hiss categorically denied the charge and subsequently sued Chambers for libel. During the pretrial discovery process of the libel case, Chambers produced new evidence allegedly indicating that he and Hiss had been involved in espionage. A federal grand jury indicted Hiss on two counts of perjury. After a mistrial due to a hung jury, Hiss was tried a second time, and in January 1950 he was found guilty and received two concurrent five-year sentences, of which he eventually served three and a half years.

In Greek mythology, Poena or Poine (Ancient Greek: Ποινή, romanized: Poinḗ, lit. 'recompense, punishment') is the spirit of punishment and the attendant of punishment to Nemesis, the goddess of divine retribution. Some depictions are of a single being, and some depictions are of multiple beings—in the plural, the name is Poenai (Ποιναί); the Poenai are akin to the Erinyes.

The Greek word ποινή (poinḗ) means "a recompense or a punishment". From this word is derived the Latin word poena meaning "pain, punishment, penalty", which in turn gave rise to English words such as subpoena and pain.

Contempt of court, often referred to simply as "contempt", is the crime of being disobedient to or disrespectful toward a court of law and its officers in the form of behavior that opposes or defies the authority, justice, and dignity of the court. A similar attitude toward a legislative body is termed contempt of Parliament or contempt of Congress. The verb for "to commit contempt" is contemn (as in "to contemn a court order") and a person guilty of this is a contemnor or contemner.

There are broadly two categories of contempt: being disrespectful to legal authorities in the courtroom, or willfully failing to obey a court order. Contempt proceedings are especially used to enforce equitable remedies, such as injunctions. In some jurisdictions, the refusal to respond to subpoena, to testify, to fulfill the obligations of a juror, or to provide certain information can constitute contempt of the court.

The impeachment process against Richard Nixon was initiated by the United States House of Representatives on October 30, 1973, during the course of the Watergate scandal, when multiple resolutions calling for the impeachment of President Richard Nixon were introduced immediately following the series of high-level resignations and firings widely called the "Saturday Night Massacre". The House Committee on the Judiciary soon began an official investigation of the president's role in Watergate, and, in May 1974, commenced formal hearings on whether sufficient grounds existed to impeach Nixon of high crimes and misdemeanors under Article II, Section 4, of the United States Constitution. This investigation was undertaken one year after the United States Senate established the Select Committee on Presidential Campaign Activities to investigate the break-in at the Democratic National Committee headquarters at the Watergate office complex during the 1972 presidential election, and the Republican Nixon administration's attempted cover-up of its involvement; during those hearings the scope of the scandal became apparent and the existence of the Nixon White House tapes was revealed.

Following an April 1974 subpoena from the Judiciary Committee, edited transcripts of 42 taped White House conversations relevant to the Watergate cover-up were finally made public by Nixon. However, the committee pressed for the audio tapes themselves, and subsequently issued subpoenas for additional tapes, all of which Nixon had refused. That same month, Nixon also refused to comply with a subpoena from special prosecutor Leon Jaworski for 64 Watergate-related tapes. Ultimately, on July 24, 1974, the United States Supreme Court issued a unanimous decision against Nixon, which ordered him to comply. On May 9, 1974, formal hearings in the impeachment inquiry of Nixon began, culminating on July 27–30, 1974, when members of the Democratic-led Judiciary Committee eventually approved three articles of impeachment. These articles charged Nixon with: (1) obstruction of justice in attempting to impede the investigation of the Watergate break-in, protect those responsible, and conceal the existence of other illegal activities; (2) abuse of power by using the office of the presidency on multiple occasions, dating back to the first year of his administration (1969), to unlawfully use federal agencies, such as the Internal Revenue Service and the Federal Bureau of Investigation, as well as establishing a covert White House special investigative unit, to violate the constitutional rights of citizens and interfere with lawful investigations; and (3) contempt of Congress by refusing to comply with congressional subpoenas. These articles were reported to the House of Representatives for final action, with 7 of the committee's 17 Republicans joining all 21 of its Democrats in voting in favor of one or more of the articles. Two other articles were debated in committee but were rejected. Based on the strength of the evidence presented and the bipartisan support for the articles in committee, House leaders of both political parties concluded that Nixon's impeachment by the full House was a certainty if it reached the House floor for a final vote, and that his conviction in a Senate trial was a distinct possibility.

Discovery, in the law of common law jurisdictions, is a phase of pretrial procedure in a lawsuit in which each party, through the law of civil procedure, can obtain evidence from other parties. This is by means of methods of discovery such as interrogatories, requests for production of documents, requests for admissions and depositions. Discovery can be obtained from nonparties using subpoenas. When a discovery request is objected to, the requesting party may seek the assistance of the court by filing a motion to compel discovery. Conversely, a party or nonparty resisting discovery can seek the assistance of the court by filing a motion for a protective order.
