The Constitution of the Dominican Republic at Art. 8 (1) refers to "the inviolability of life" and states: "Therefore, neither the death penalty, torture nor any other punishment or oppressive procedure or penalty that implies loss or diminution of the physical integrity or health of the individual may be established." The Dominican Republic has been fully abolitionist since 1966, and the death penalty was replaced with 30 years hard labour way back in 1911. Hard labour penalty was replaced by imprisonment with the Prison Reform Act, which states prisoners shall not be subjected to torture, ill treatment, harmful practices or humiliation of any kind.
On 23 September 2016, the Dominican Republic acceded to the Second Optional Protocol to the International Covenant on Civil and Political Rights, aiming at the abolition of the death penalty.
