Death sentence

"Death sentence" and "death penalty" were common names for the capital punishment of execution — the state-sanctioned death of an individual for crimes of an especially grave nature, such as murder or treason. Sometimes, especially in Earth's past, or in places without clear governmental structures, it could be carried out against people for less profound crimes, or even for no substantive reason at all.

Earth
On Earth, it was a divisive issue. Some people, such as the Briton Professor Kettering, believed that the death penalty was a backwards conception of justice. (TV: The Mind of Evil) To the contrary, many Americans in Jacksonville, Kentucky on "Miracle Day" fully believed that the rapist and murderer Oswald Danes should not have been paroled after his death by lethal injection failed. (TV: The New World)

Indeed, there was a general divide between the British and American viewpoints on the issue. The death penalty was abolished in the United Kingdom at least by the late 20th century, (TV: The Mind of Evil) whereas it was still an acceptable punishment in at least the state of Kentucky as late as the year 2011. (TV: The New World)

Gallifrey
Time Lords exercised the death penalty, largely for crimes against the Laws of Time.

It was applied at least until the presidency previous to the Fourth Doctor's one (TV: The Deadly Assassin) but, by the time of Borusa's presidency, capital punishment was said to had long been abolished. (TV: Arc of Infinity)

Vapourisation was the penalty for setting oneself up as a god in a more primitive civilisation (AUDIO: False Gods) or for the murder of a Lord President. (TV: The Deadly Assassin)

The death penalty on Gallifrey was sometimes effected through a "Warrant of Termination". One was served on the Fifth Doctor. In that instance, however, he wasn't threatened with death (through molecular dispersal) because of any actual wrongdoing, but because he had become controlled by a malevolent entity that posed a grave risk to the entire universe. (TV: Arc of Infinity)

There existed a far worse death penalty for Gallifreyans, and sometimes offworlders, which was the Oubliette of Eternity where you were not only killed but your whole life was removed from the Web of Time, and, unknown to the Time Lords, became Neverpeople. This was the preferred method of sentencing death by the Celestial Intervention Agency. (AUDIO: Neverland)
