Royal prerogative of mercy


In the English and British tradition, the royal prerogative of mercy is one of the historic royal prerogatives of the British monarch, by which he or she can grant pardons to convicted persons. The royal prerogative of mercy was originally used to permit the monarch to withdraw, or provide alternatives to death sentences; the alternative of penal transportation to "partes abroade" has been used since at least 1617. It is now used to change any sentence or penalty. A royal pardon does not itself overturn a conviction.
Officially, this is a power of the monarch. Formally, in Commonwealth realms, this has been delegated to the governor-general of the realm, which in practice means to government ministers who advise the monarch or viceroy, usually those responsible for justice. Specifically, it has been delegated to the Lord Chancellor in England and Wales, the Scottish Ministers in Scotland, and the federal and provincial cabinets in Canada, in respect of federal and provincial offences.
In the important case of Derek Bentley, a court found that this royal prerogative power is "probably" entirely a matter of policy, and thus not justiciable.

Examples in Britain

In 2001 two inmates at HMP Prescoed, south Wales, received early release under the prerogative of mercy as a reward for saving the life of the manager of the prison farm when he was attacked and gored by a captive wild boar.
In 2013 a posthumous pardon was awarded to Alan Turing under the prerogative of mercy. Wartime codebreaker Turing had been convicted in 1952 of gross indecency for a consensual homosexual relationship with an adult.

In other Commonwealth realms

In Australia, the governor-general acts on the advice of the attorney-general or minister for justice, and may only exercise the prerogative of mercy in relation to a federal offender convicted of a Commonwealth offence. The pardon may be a full pardon, a conditional pardon, a remission or partial remission of a penalty, or the ordering of an inquiry. Each state and territory has also enacted legislation providing for the reconsideration of convictions or sentences.
In New Zealand, the prerogative of mercy is exercised by the governor-general, as the Queen's representative, with the power being delegated by the Letters Patent 1983. The governor-general will act on the advice of the minister of justice, and has the power to grant a pardon, refer a case back to the courts for reconsideration, and to reduce a person's sentence.
