On 1 July 2017, entered into force the new Criminal Code that abolishes the death penalty for all crimes, approved in 2015.
The last execution in Mongolia was in 2008 and the death penalty remained classified as a state secret. 
Since then, the country has taken a series of steps towards abolition culminating in the historic parliamentary vote. In 2010, the country’s President, Tsakhia Elbegdorj, commuted all death sentences and announced a moratorium on all executions. In 2012, Mongolia acceded to the Second Optional Protocol to the International Covenant on Civil and Political Rights (ICCPR), committing the country to the abolition of the death penalty. 
In 2011 Hands off Cain awarded President Tsakhia Elbegdorj with the “Abolitionist of the Year Prix.”
However, the new President Khaltmaagiin Battulga repeatedly invoked the death penalty and on 27 November presented a proposal to the Ministry of Justice to reintroduce the death penalty.

On 29 September 2017, Mongolia voted again in favour of the Resolution on the Death Penalty at the 36° session of the UN Council on Human Rights. 
On 17 December 2018, Mongolia co-sponsored and voted again in favour of the Resolution on a Moratorium on the Use of the Death Penalty at the UN General Assembly.
