The death penalty has been in Ghana’s statute books...

The death penalty has been in Ghana’s statute books since the inception of English common law in the country in 1874. 
Ghana still retains the death penalty for armed robbery, treason and first-degree murder.
Under Article 72 of the Constitution the president may exercise the Prerogative of Mercy and grant amnesty.
According to human rights activists and the Ghana Bar Association, at least 155 people were executed between 1984 and 1993 when former President Jerry Rawlings headed an iron-fisted military government. Many were soldiers suspected of coup plotting.
The 2000 presidential and parliamentary elections – the first in the country that saw a transfer of power through elections – saw John Kufuor take over from Jerry Rawlings, who had been in power for over 20 years as coup leader first, then as democratically-elected president since 1992.
In April 2000, 100 people had their death sentences commuted to life terms. In February 2001, the then Justice Minister, and present Foreign Minister, Nana Akufo-Addo, spoke out publicly against the death penalty. In June 2003, nearly ten years after the last execution (July 1993), President John Agyekum Kufuor, known as the "Gentle Giant", granted amnesty to 179 prisoners that had spent at least ten years on death row.
No executions have taken place since July 1993, when 12 prisoners who had been convicted of armed robbery or murder were executed by firing squad. Executions may also be carried out by hanging but Ghana's last hanging was performed in 1968.
On March 6, 2007 Ghana’s President, John Kufuor, freed or commuted the sentences of 1,206 prisoners to mark the 50th anniversary of independence, according to an Interior Ministry statement. Thirty-six prisoners who were on death row have had their sentences commuted to life in prison.
Three prisoners who were serving life sentences had their jail terms reduced to 20 years. And 1,167 detainees serving lesser sentences have been freed, said the statement.
The statement did not say exactly when the changes would take effect.
Ghana's prison population stands at just under 12,000. The provision is part of a long series of amnesties in the past years on the part of President John Kufuor, devoted Catholic and known as “the good giant of Africa.”
On December 18, 2007 Ghana abstained on the Resolution on a Moratorium on the Use of the Death Penalty at the UN General Assembly.
