Treason is the crime of attacking a state authority to which one owes allegiance. This typically includes acts such as participating in a war against one's native country, attempting to overthrow its government, spying on its military, its diplomats, or its secret services for a hostile and foreign power, or attempting to kill its head of state. A person who commits treason is known in law as a traitor.
In jurisprudence, duress or coercion refers to a situation whereby a person performs an act as a result of violence, threat, or other pressure against the person. Black's Law Dictionary defines duress as "any unlawful threat or coercion used... to induce another to act [or not act] in a manner [they] otherwise would not [or would]". Duress is pressure exerted upon a person to coerce that person to perform an act they ordinarily would not perform. The notion of duress must be distinguished both from undue influence in the civil law. In criminal law, duress and necessity are different defenses.
Capital punishment in the United Kingdom predates the formation of the UK, having been used in Britain and Ireland from ancient times until the second half of the 20th century. The last executions in the United Kingdom were by hanging, and took place in 1964; capital punishment for murder was suspended in 1965 and finally abolished in 1969. Although unused, the death penalty remained a legally defined punishment for certain offences such as treason until it was completely abolished in 1998; the last person to be executed for treason was William Joyce, in 1946. In 2004, Protocol No. 13 to the European Convention on Human Rights became binding on the United Kingdom; it prohibits the restoration of the death penalty as long as the UK is a party to the convention.
In common law jurisdictions, an acquittal means that the criminal prosecution has failed to prove that the accused is guilty beyond a reasonable doubt of the charge presented. It certifies that the accused is free from the charge of an offense, as far as criminal law is concerned. The finality of an acquittal is dependent on the jurisdiction. In some countries, such as the United States, an acquittal prohibits the retrial of the accused for the same offense, even if new evidence surfaces that further implicates the accused. The effect of an acquittal on criminal proceedings is the same whether it results from a jury verdict or results from the operation of some other rule that discharges the accused. In other countries, like Australia and the UK, the prosecuting authority may appeal an acquittal similar to how a defendant may appeal a conviction — but usually only if new and compelling evidence comes to light or the accused has interfered with or intimidated a juror or witness.
Capital punishment is a legal penalty in the U.S. state of Indiana. The last person executed in the state, excluding federal executions in Terre Haute, was mass murderer Joseph Edward Corcoran in 2024.
Under the law of the United Kingdom, high treason is the crime of disloyalty to the Crown. Offences constituting high treason include plotting the murder of the sovereign; committing adultery with the sovereign's consort, with the sovereign's eldest unmarried daughter, or with the wife of the heir to the throne; levying war against the sovereign and adhering to the sovereign's enemies, giving them aid or comfort; and attempting to undermine the lawfully established line of succession. Several other crimes have historically been categorised as high treason, including counterfeiting money and being a Catholic priest.

Attempted murder is a crime of attempt in various jurisdictions.
Gregg v. Georgia, Proffitt v. Florida, Jurek v. Texas, Woodson v. North Carolina, and Roberts v. Louisiana, 428 U.S. 153 (1976), is a landmark decision of the U.S. Supreme Court. It reaffirmed the Court's acceptance of the use of the death penalty in the United States, upholding, in particular, the death sentence imposed on Troy Leon Gregg. The set of cases is referred to by a leading scholar as the July 2 Cases, and elsewhere referred to by the lead case Gregg. The court set forth the two main features that capital sentencing procedures must employ in order to comply with the Eighth Amendment ban on "cruel and unusual punishments". The decision essentially ended the de facto moratorium on the death penalty imposed by the Court in its 1972 decision in Furman v. Georgia (1972). Justice Brennan's dissent famously argued that "The calculated killing of a human being by the State involves, by its very nature, a denial of the executed person's humanity ... An executed person has indeed 'lost the right to have rights.'"
The Treason Act 1351 is an Act of the Parliament of England wherethrough, according to William Blackstone, common law treason offences were enumerated and no new offences were, by statute, created. It is one of the earliest English statutes still in force, although it has been very significantly amended. It was extended to Ireland in 1495 and to Scotland in 1708. The Act was passed at Westminster in the Hilary term of 1351, in the 25th year of the reign of Edward III and was entitled "A Declaration which Offences shall be adjudged Treason". It was passed to clarify precisely what was treason, as the definition under common law had been expanded rapidly by the courts until its scope was controversially wide. The Act was last used to prosecute William Joyce in 1945 for collaborating with Germany in World War II.
Capital murder refers to a category of murder in some parts of the US for which the perpetrator is eligible for the death penalty. In its original sense, capital murder was a statutory offence of aggravated murder in Great Britain, Northern Ireland, and the Republic of Ireland, which was later adopted as a legal provision to define certain forms of aggravated murder in the United States. Some jurisdictions that provide for death as a possible punishment for murder, such as California, do not have a specific statute creating or defining a crime known as capital murder; instead, death is one of the possible sentences for certain kinds of murder. In these cases, "capital murder" is not a phrase used in the legal system but may still be used by others such as the media.
Capital punishment is a legal penalty in the U.S. state of Texas for murder, and participation in a felony resulting in death if committed by an individual who has attained or is over the age of 18.

A threat is a communication of intent to inflict harm or loss on another person. Intimidation is a tactic used between conflicting parties to make the other timid or psychologically insecure for coercion or control. The act of intimidation for coercion is considered a threat.
Capital punishment in Ireland was abolished in statute law in 1990, having been abolished in 1964 for most offences including ordinary murder. The last person to be executed was Michael Manning, hanged for murder in 1954. All subsequent death sentences in Ireland, the last handed down in 1985, were commuted by the President, on the advice of the Government, to terms of imprisonment of up to 40 years. The Twenty-first Amendment to the constitution, passed by referendum in 2001, prohibits the reintroduction of the death penalty, even during a state of emergency or war. Capital punishment is also forbidden by several human rights treaties to which the state is a party.
Marital coercion was a defence to most crimes under English criminal law and under the criminal law of Northern Ireland. It is similar to duress. It was abolished in England and Wales by section 177 of the Anti-social Behaviour, Crime and Policing Act 2014, which came into force on 13 May 2014. The abolition does not apply in relation to offences committed before that date.
Threatening the president of the United States is a federal felony under United States Code Title 18, Section 871. It consists of knowingly and willfully mailing or otherwise making "any threat to take the life of, to kidnap, or to inflict great bodily harm upon the president of the United States". The law also includes presidential candidates, vice presidents, and former presidents. The Secret Service investigates suspected violations of this law and monitors those who have a history of threatening the president. Threatening the president is considered a political offense. Immigrants who commit this crime can be deported.
In the United States, the law for murder varies by jurisdiction. In many US jurisdictions there is a hierarchy of acts, known collectively as homicide, of which first-degree murder and felony murder are the most serious, followed by second-degree murder and, in a few states, third-degree murder, which in other states is divided into voluntary manslaughter, and involuntary manslaughter such as reckless homicide and negligent homicide, which are the least serious, and ending finally in justifiable homicide, which is not a crime. However, because there are at least 52 relevant jurisdictions, each with its own criminal code, this is a considerable simplification.
Capital punishment in Delaware was formally abolished in 2024, however it has not been enforced after Delaware’s capital punishment statues were declared unconstitutional by the Delaware Supreme Court on August 2, 2016. The ruling retroactively applies to earlier death sentences, and remaining Delaware death row inmates had their sentences commuted to life imprisonment. The capital statute for first-degree murder under Title 11, Chapter 42, Section 09, of the Delaware Code was fully repealed on September 26, 2024.
Capital punishment in Malawi is a legal punishment for certain crimes. The country abolished the death penalty following a Malawian Supreme Court ruling in 2021, but it was soon reinstated. However, the country is currently under a death penalty moratorium, which has been in place since the latest execution in 1992.
