Death row is a special section of a prison that houses inmates who are awaiting execution after being sentenced to death for the conviction of capital crimes. The term is also used figuratively to describe the state of awaiting execution ("being on death row"), even in places where no special facility or separate unit for condemned inmates exists. After a person is found guilty of a capital offense, the judge will give the jury the option of imposing a death sentence or life imprisonment without the possibility of parole. It is then up to a jury to decide whether to give the death sentence; this usually has to be a unanimous decision. If the jury agrees on death, the defendant will remain on death row during appeal and habeas corpus procedures, which can drag on for many years.
Opponents of capital punishment claim that a prisoner's isolation and uncertainty over his or her fate constitute a form of mental cruelty and that especially long-time death row inmates are liable to become mentally ill, if they are not already. This is referred to as the death row phenomenon. In extreme cases some inmates may attempt to commit suicide.
In the United States, prisoners may wait many years before execution can be carried out due to the complex and time-consuming appeals procedures mandated in the jurisdiction. The time between sentencing and execution has increased relatively steadily between 1977 and 2010, including a 22% jump between 1989 and 1990 and a similar jump between 2008 and 2009. In 2010, a death row inmate waited an average of 178 months (roughly 15 years) between sentencing and execution. Nearly a quarter of inmates on death row in the U.S. die of natural causes while awaiting execution.
When the United Kingdom had capital punishment, sentenced inmates were given one appeal. If that appeal was found to involve an important point of law it was taken up to the House of Lords, and if the appeal was successful, at that point the sentence was changed to life in prison. The Home Secretary in the United Kingdom had the power to exercise the Sovereign's royal prerogative of mercy to grant a reprieve on execution and change the sentence to life imprisonment.
