The Death Penalty in the OSCE Area–Background Paper 2017 6. While it follows from article 6 (2) to (6) that States parties are not obliged to abolish the death penalty totally they are obliged to limit its use and, in particular, to abolish it for other than the “most serious crimes”. Accordingly, they ought to consider reviewing their criminal laws in this light and, in any event, are obliged to restrict the application of the death penalty to the “most serious crimes”. The article also refers generally to abolition in terms which strongly suggest (paras. 2 (2) and (6)) that abolition is desirable.

The procedural guarantees therein prescribed must be observed, including the right to a fair hearing by an independent tribunal, the presumption of innocence, the minimum guarantees for the defence, and the right to review by a higher tribunal. These rights are applicable in addition to the particular right to seek pardon or commutation of the sentence. United Nations General Assembly Resolution 62/149: Moratorium on the use of the death penalty (2007) The General Assembly, […] Considering that the use of the death penalty undermines human dignity, and convinced that a moratorium on the use of the death penalty contributes to the enhancement and progressive development of human rights, that there is no conclusive evidence of the deterrent value of the death penalty and that any miscarriage or failure of justice in the implementation of the death penalty is irreversible and irreparable, Welcoming the decisions taken by an increasing number of States to apply a moratorium on executions, followed in many cases by the abolition of the death penalty, 55
