Other meanings of Second Optional Protocol to the International Covenant on Civil and Political Rights
International Law
The Second Optional Protocol to the International Covenant on Civil and Political Rights, aiming at the abolition of the death penalty, is a 1989 United Nations treaty that commits its parties to abolish capital punishment within their jurisdictions. Adopted by the UN General Assembly on 15 December 1989 and opened for signature in 1990, it supplements the International Covenant on Civil and Political Rights (ICCPR) by prohibiting executions and requiring states to take all necessary measures to abolish the death penalty. The Protocol has been ratified by over 90 states, reflecting a global trend toward abolition, though several major retentionist countries remain outside its framework.
The Second Optional Protocol was adopted by the UN General Assembly on 15 December 1989 by a vote of 59 in favour, 26 against, and 48 abstentions, and was opened for signature on 31 December 1989.1 It entered into force on 11 July 1991, after the tenth instrument of ratification or accession was deposited. The Protocol complements the ICCPR, which itself does not prohibit the death penalty but restricts its application; the Protocol goes further by prohibiting executions entirely and requiring states to abolish capital punishment within their jurisdiction. As of 2024, 92 states are parties, with several others having signed but not yet ratified.2
Article 1 contains the core obligation: no one within the jurisdiction of a state party shall be executed, and each state party shall take all necessary measures to abolish the death penalty. Article 2 prohibits reservations except those allowing execution in time of war for the most serious crimes of a military nature, a provision that has been used by a few states such as Brazil and Chile. Article 3 requires states to report to the Human Rights Committee on measures implementing the Protocol, and Article 4 ensures that the Protocol does not derogate from other obligations under the ICCPR or other instruments. The Protocol also establishes that its provisions apply to all parts of federal states without limitation.3
The Human Rights Committee, the treaty body for the ICCPR, monitors compliance with the Second Optional Protocol. States parties must submit periodic reports, and the Committee issues concluding observations that often urge states to ensure no executions occur and to consider withdrawing reservations. The Committee has also addressed individual communications under the First Optional Protocol, clarifying that the Second Protocol creates a non-derogable right to life in the context of capital punishment. In its General Comment No. 36 on the right to life, the Committee affirmed that the Second Protocol represents a clear step toward the universal abolition of the death penalty.4
One lesser-known aspect is the Protocol's role in regional human rights systems: it has been cited by the Inter-American Court of Human Rights and the European Court of Human Rights as evidence of an emerging international consensus against the death penalty. Another is the reservation practice: only a handful of states have entered the war-time reservation, and some have later withdrawn it, such as Spain. The Protocol also influenced the drafting of the Statute of the International Criminal Court, which excludes the death penalty from its penalties. Additionally, the Protocol's adoption was driven by a coalition of abolitionist states, including several from Europe and Latin America, and it has been used as a benchmark in UN resolutions calling for a moratorium on executions.5
The Second Optional Protocol is a landmark instrument in the global movement to abolish the death penalty, reflecting a growing international consensus that capital punishment violates the right to life.
