15 September 2008 :

Argentina ratified the Second Optional Protocol to the International Covenant on Civil and Political Rights aimed at the abolition of the death penalty. This was followed by the government's ratification of the Protocol to the American Convention on Human Rights to Abolish the Death Penalty.
Both of these instruments were ratified without reservations.
This latest initiative paves the way for other countries to follow suit, and makes Argentina the sixth country to ratify all the human rights instruments of the inter-American system.
"To have ratified all of the important human rights instruments of the inter-American system is a very positive development, but must be followed through by their full implementation", said Susan Lee, Americas Director at Amnesty International.
