I. General remarks

1. This general comment replaces earlier general comments No. 6 (16th session) and 14 (23rd session) adopted by the Committee in 1982 and 1984, respectively.

2. Article 6 recognizes and protects the right to life of all human beings. It is the supreme right from which no derogation is permitted even in situations of armed conflict and other public emergencies which threatens the life of the nation.[Footnote 1] The right to life has crucial importance both for individuals and for society as a whole. It is most precious for its own sake as a right that inheres in every human being, but it also constitutes a fundamental right [Footnote 2] whose effective protection is the prerequisite for the enjoyment of all other human rights and whose content can be informed by other human rights.

3. The right to life is a right which should not be interpreted narrowly. It concerns the entitlement of individuals to be free from acts and omissions that are intended or may be expected to cause their unnatural or premature death, as well as to enjoy a life with dignity. Article 6 guarantees this right for all human beings, without distinction of any kind, including for persons suspected or convicted of even the most serious crimes.

4. Paragraph 1 of article 6 of the Covenant provides that no one shall be arbitrarily deprived of his life and that the right shall be protected by law. It lays the foundation for the obligation of States parties to respect and to ensure the right to life, to give effect to it through legislative and other measures, and to provide effective remedies and reparation to all victims of violations of the right to life.

5. Paragraphs 2, 4, 5 and 6 of article 6 of the Covenant set out specific safeguards for ensuring that in States parties which have not yet abolished the death penalty, it must not be applied except for the most serious crimes, and then only in the most exceptional cases and under the strictest limits. [Footnote 3] The prohibition on arbitrary deprivation of life contained in article 6, paragraph 1 further limits the ability of States parties to apply the death penalty. The provisions of paragraph 3 regulate specifically the relationship between Article 6 of the Covenant and the Convention on the Prevention and Punishment of the Crime of Genocide (‘the Genocide Convention’).

6. Deprivation of life involves an intentional [Footnote 4] or otherwise foreseeable and preventable life-terminating harm or injury, caused by an act or omission. It goes beyond injury to bodily or mental integrity or threat thereto. [Footnote 5]

7. States parties must respect the right to life and have the duty to refrain from engaging in conduct resulting in arbitrary deprivation of life. States parties must also ensure the right to life and exercise due diligence to protect the lives of individuals against deprivations caused by persons or entities, whose conduct is not attributable to the State. [Footnote 6] The obligation of States parties to respect and ensure the right to life extends to reasonably foreseeable threats and life-threatening situations that can result in loss of life. States parties may be in violation of article 6 even if such threats and situations do not result in loss of life. [Footnote 7]

8. Although States parties may adopt measures designed to regulate voluntary terminations of pregnancy, such measures must not result in violation of the right to life of a pregnant woman or girl, or her other rights under the Covenant. Thus, restrictions on the ability of women or girls to seek abortion must not, inter alia, jeopardize their lives, subject them to physical or mental pain or suffering which violates article 7, discriminate against them or arbitrarily interfere with their privacy. States parties must provide safe, legal and effective access to abortion where the life and health of the pregnant woman or girl is at risk, or where carrying a pregnancy to term would cause the pregnant woman or girl substantial pain or suffering, most notably where the pregnancy is the result of rape or incest or is not viable. [Footnote 8] In addition, States parties may not regulate pregnancy or abortion in all other cases in a manner that runs contrary to their duty to ensure that women and girls do not have to undertake unsafe abortions, and they should revise their abortion laws accordingly. [Footnote 9] For example, they should not take measures such as criminalizing pregnancies by unmarried women or apply criminal sanctions against women and girls undergoing abortion [Footnote 10] or against medical service providers assisting them in doing so, since taking such measures compel women and girls to resort to unsafe abortion. States parties should not introduce new barriers and should remove existing barriers [Footnote 11] that deny effective access by women and girls to safe and legal abortion [Footnote 12], including barriers caused as a result of the exercise of conscientious objection by individual medical providers. [Footnote 13] States parties should also effectively protect the lives of women and girls against the mental and physical health risks associated with unsafe abortions. In particular, they should ensure access for women and men, and, especially, girls and boys, [Footnote 14] to quality and evidence-based information and education about sexual and reproductive health [Footnote 15] and to a wide range of affordable contraceptive methods, [Footnote 16] and prevent the stigmatization of women and girls seeking abortion. [Footnote 17] States parties should ensure the availability of, and effective access to, quality prenatal and post-abortion health care for women and girls, [Footnote 18] in all circumstances, and on a confidential basis. [Footnote 19]

9. While acknowledging the central importance to human dignity of personal autonomy, States should take adequate measures, without violating their other Covenant obligations, to prevent suicides, especially among individuals in particularly vulnerable situations, [Footnote 20] including individuals deprived of their liberty. States parties that allow medical professionals to provide medical treatment or the medical means in order to facilitate the termination of life of afflicted adults, such as the terminally ill, who experience severe physical or mental pain and suffering and wish to die with dignity, [Footnote 21] must ensure the existence of robust legal and institutional safeguards to verify that medical professionals are complying with the free, informed, explicit and, unambiguous decision of their patients, with a view to protecting patients from pressure and abuse. [Footnote 22]

II. The Prohibition against Arbitrary Deprivation of Life

10. Although it inheres in every human being [Footnote 23] the right to life is not absolute. The Covenant does not provide an enumeration of permissible grounds for deprivation of life, but by requiring that deprivations of life must not be arbitrary, Article 6, paragraph 1 implicitly recognizes that some deprivations of life may be non-arbitrary. For example, the use of lethal force in self-defence, under the conditions specified in paragraph 12 below would not constitute an arbitrary deprivation of life. Even those exceptional measures leading to deprivations of life which are not arbitrary per se must be applied in a manner which is not arbitrary in fact. Such exceptional measures should be established by law and accompanied by effective institutional safeguards designed to prevent arbitrary deprivations of life. Furthermore, States which have not abolished the death penalty and which are not parties to the Second Optional Protocol or other treaties providing for the abolition of the death penalty can only apply the death penalty in a non-arbitrary manner, with regard to the most serious crimes and subject to a number of strict conditions elaborated in part IV below.

11. The second sentence of paragraph 1 of Article 6 requires that the right to life be protected by law, while the third sentence requires that no one should be arbitrarily deprived of life. The two requirements partly overlap in that a deprivation of life that lacks a legal basis or is otherwise inconsistent with life-protecting laws and procedures is, as a rule, arbitrary in nature. For example, a death sentence issued following legal proceedings conducted in violation of domestic laws of criminal procedure or evidence will generally be both unlawful and arbitrary.

12. Deprivation of life is, as a rule, arbitrary if it is inconsistent with international law or domestic law. [Footnote 24] A deprivation of life may, nevertheless, be authorized by domestic law and still be arbitrary. The notion of “arbitrariness” is not to be fully equated with “against the law”, but must be interpreted more broadly to include elements of inappropriateness, injustice, lack of predictability, and due process of law [Footnote 25] as well as elements of reasonableness, necessity, and proportionality. In order not to be qualified as arbitrary under article 6, the application of potentially lethal force by a private person acting in self-defense, or by another person coming to his or her defence, must be strictly necessary in view of the threat posed by the attacker; it must represent a method of last resort after other alternatives have been exhausted or deemed inadequate; [Footnote 26] the amount of force applied cannot exceed the amount strictly needed for responding to the threat; the force applied must be carefully directed only against the attacker; [Footnote 27] and the threat responded to must involve imminent death or serious injury. [Footnote 28] The use of potentially lethal force for law enforcement purposes is an extreme measure [Footnote 29], which should be resorted to only when strictly necessary in order to protect life or prevent serious injury from an imminent threat. [Footnote 30] It cannot be used, for example, in order to prevent the escape from custody of a suspected criminal or a convict who does not pose a serious and imminent threat to the lives or bodily integrity of others. [Footnote 31] The intentional taking of life by any means is permissible only if it is strictly necessary in order to protect life from an imminent threat. [Footnote 32]

13. States parties are expected to take all necessary measures intended to prevent arbitrary deprivations of life by their law enforcement officials, including soldiers charged with law enforcement missions. These measures include appropriate legislation controlling the use of lethal force by law enforcement officials, procedures designed to ensure that law enforcement actions are adequately planned in a manner consistent with the need to minimize the risk they pose to human life, [Footnote 33] mandatory reporting, review, and investigation of lethal incidents [Footnote 34] and other life-threatening incidents, and the supplying of forces responsible for crowd control with effective “less-lethal” means and adequate protective equipment in order to obviate their need to resort to lethal force. [Footnote 35] In particular, all operations of law enforcement officials should comply with relevant international standards, including the Code of Conduct for Law Enforcement Officials (General Assembly resolution 34/169)(1979) and the Basic Principles on the Use of Force and Firearms by Law Enforcement Officials (1990), [Footnote 36] and law enforcement officials should undergo appropriate training designed to inculcate these standards [Footnote 37] so as to ensure, in all circumstances, the fullest respect for the right to life. [Footnote 38]

14. While preferable to more lethal weapons, States parties should ensure that “less-lethal” weapons are subject to strict independent testing and evaluate and monitor the impact on the right to life of weapons such as electro-muscular disruption devices (Tasers), [Footnote 39] rubber or foam bullets, and other attenuating energy projectiles, [Footnote 40] which are designed for use or are actually used by law enforcement officials, including soldiers charged with law enforcement missions. [Footnote 41] The use of such weapons must be restricted to law enforcement officials who have undergone appropriate training, and must be strictly regulated in accordance with applicable international standards, including the Basic Principles on the Use of Force and Firearms by Law Enforcement Officials. [Footnote 42] Furthermore, such “less-lethal” weapons can only be employed, subject to strict requirements of necessity and proportionality, in situations in which other less harmful measures have proven to be, or clearly are ineffective to address the threat. [Footnote 43] States parties should not resort to “less-lethal” weapons in situations of crowd control which can be addressed through less harmful means, [Footnote 44] especially situations involving the exercise of the right to peaceful assembly.

15. When private individuals or entities are empowered or authorized by a State party to employ force with potentially lethal consequences, the State party is under an obligation to ensure that such employment of force actually complies with article 6 and remains responsible for any failure to comply. [Footnote 45] Among other things, a State party must rigorously limit the powers afforded to private actors, and ensure that strict and effective measures of monitoring and control, and adequate training, are in place, in order to guarantee, inter alia, that the powers granted are not misused, and do not lead to arbitrary deprivation of life. For example, a State party must take adequate measures to ensure that persons who were involved or are currently involved in serious human rights violations or abuses are excluded from private security entities empowered or authorized to employ force. [Footnote 46] It must also ensure that victims of arbitrary deprivation of life by private individuals or entities empowered or authorized by the State party are granted an effective remedy. [Footnote 47]

16. Article 6, paragraphs 2, 4 and 5 implicitly recognize that countries which have not abolished the death penalty and that have not ratified the Second Optional Protocol are not legally barred under the Covenant from applying the death penalty with regard to the most serious crimes subject to a number of strict conditions. Other procedures regulating activity that may result in deprivation of life, such as protocols for administering new drugs, must be established by law, accompanied by effective institutional safeguards designed to prevent arbitrary deprivation of life, and be compatible with other provisions of the Covenant.

17. The deprivation of life of individuals through acts or omissions that violate provisions of the Covenant other than article 6 is, as a rule, arbitrary in nature. This includes, for example, the use of force resulting in the death of demonstrators exercising their right of freedom of assembly; [Footnote 48] and the passing of a death sentence following a trial which failed to meet the due process requirements of article 14 of the Covenant. [Footnote 49]

III. The Duty to Protect Life

18. The second sentence of paragraph 1 provides that the right to life “shall be protected by law”. This implies that States parties must establish a legal framework to ensure the full enjoyment of the right to life by all individuals as may be necessary to give effect to the right to life. The duty to protect the right to life by law also includes an obligation for States parties to adopt any appropriate laws or other measures in order to protect life from all reasonably foreseeable threats, including from threats emanating from private persons and entities.

19. The duty to protect by law the right to life entails that any substantive ground for deprivation of life must be prescribed by law, and defined with sufficient precision to avoid overly broad or arbitrary interpretation or application. [Footnote 50] Since deprivation of life by the authorities of the State is a matter of the utmost gravity, the law must strictly control and limit the circumstances in which a person may be deprived of his life by such authorities [Footnote 51] and the States parties must ensure full compliance with all of the relevant legal provisions. The duty to protect by law the right to life also requires States parties to organize all State organs and governance structures through which public authority is exercised in a manner consistent with the need to respect and ensure the right to life, [Footnote 52] including establishing by law adequate institutions and procedures for preventing deprivation of life, investigating and prosecuting potential cases of unlawful deprivation of life, meting out punishment and providing full reparation.

20. States parties must enact a protective legal framework which includes effective criminal prohibitions on all manifestations of violence or incitement to violence that are likely to result in a deprivation of life, such as intentional and negligent homicide, unnecessary or disproportionate use of firearms, [Footnote 53] infanticide, [Footnote 54] “honour” killings, [Footnote 55] lynching, [Footnote 56] violent hate crimes, [Footnote 57] blood feuds, [Footnote 58] ritual killings. [Footnote 59], death threats, and terrorist attacks. The criminal sanctions attached to these crimes must be commensurate with their gravity, [Footnote 60] while remaining compatible with all provisions of the Covenant.

21. The duty to take positive measures to protect the right to life derives from the general duty to ensure the rights recognized in the Covenant, which is articulated in article 2, paragraph 1, when read in conjunction with article 6, as well as from the specific duty to protect the right to life by law which is articulated in the second sentence of article 6. States parties are thus under a due diligence obligation to undertake reasonable positive measures, which do not impose on them disproportionate burdens, [Footnote 61] in response to reasonably foreseeable threats to life originating from private persons and entities, whose conduct is not attributable to the State. [Footnote 62] Hence, States parties are obliged to take adequate preventive measures in order to protect individuals against reasonably foreseen threats of being murdered or killed by criminals and organized crime or militia groups, including armed or terrorist groups. [Footnote 63] States parties should also disband irregular armed groups, such as private armies and vigilante groups, that are responsible for deprivations of life [Footnote 64] and reduce the proliferation of potentially lethal weapons to unauthorized individuals. [Footnote 65] States parties must further take adequate measures of protection, including continuous supervision, [Footnote 66] in order to prevent, investigate, punish and remedy arbitrary deprivation of life by private entities, such as private transportation companies, private hospitals [Footnote 67] and private security firms. [Footnote 68]

22. States parties must take appropriate measures to protect individuals against deprivation of life by other States, international organizations and foreign corporations operating within their territory [Footnote 69] or in other areas subject to their jurisdiction. They must also take appropriate legislative and other measures to ensure that all activities taking place in whole or in part within their territory and in other places subject to their jurisdiction, but having a direct and reasonably foreseeable impact on the right to life of individuals outside their territory, including activities taken by corporate entities based in their territory or subject to their jurisdiction, [Footnote 70] are consistent with article 6, taking due account of related international standards of corporate responsibility, [Footnote 71] and of the right of victims to obtain an effective remedy.

23. The duty to protect the right to life requires States parties to take special measures of protection towards persons in situation of vulnerability whose lives have been placed at particular risk because of specific threats [Footnote 72] or pre-existing patterns of violence. These include human rights defenders, [Footnote 73] officials fighting corruption and organized crime, humanitarian workers, journalists, [Footnote 74] prominent public figures, witnesses to crime, [Footnote 75] and victims of domestic and gender-based violence and human trafficking. They may also include children, [Footnote 76] especially children in street situations, unaccompanied migrant children and children in situations of armed conflict, members of ethnic and religious minorities [Footnote 77] and indigenous peoples, [Footnote 78] lesbian, gay, bisexual, transgender and inter-sex (LGBTI) persons, [Footnote 79] persons with albinism, [Footnote 80] alleged witches, [Footnote 81] displaced persons, asylum seekers, refugees [Footnote 82] and stateless persons. States parties must respond urgently and effectively in order to protect individuals who find themselves under a specific threat, by adopting special measures such as the assignment of around-the-clock police protection, the issuance of protection and restraining orders against potential aggressors and, in exceptional cases, and only with the free and informed consent of the threatened individual, protective custody.

24. Persons with disabilities, including psychosocial and intellectual disabilities, are also entitled to specific measures of protection so as to ensure their effective enjoyment of the right to life on equal basis with others. [Footnote 83] Such measures of protection shall include the provision of reasonable accommodation when necessary to ensure the right to life, such as ensuring access of persons with disabilities to essential facilities and services, [Footnote 84] and specific measures designed to prevent unwarranted use of force by law enforcement agents against persons with disabilities. [Footnote 85]

25. States parties also have a heightened duty of care to take any necessary measures [Footnote 86] to protect the lives of individuals deprived of their liberty by the State, since by arresting, detaining, imprisoning or otherwise depriving individuals of their liberty, States parties assume the responsibility to care for their life [Footnote 87] and bodily integrity, and they may not rely on lack of financial resources or other logistical problems to reduce this responsibility. [Footnote 88] The same heightened duty of care attaches to individuals held in private incarceration facilities operating pursuant to an authorization by the State. The duty to protect the life of all detained individuals includes providing them with the necessary medical care and appropriately regular monitoring of their health, [Footnote 89] shielding them from inter-prisoner violence, [Footnote 90] preventing suicides and providing reasonable accommodation for persons with disabilities. [Footnote 91] A heightened duty to protect the right to life also applies to individuals quartered in liberty-restricting State-run facilities, such as mental health facilities, [Footnote 92] military camps, [Footnote 93] refugee camps and camps for internally displaced persons, [Footnote 94] juvenile institutions and orphanages.

26. The duty to protect life also implies that States parties should take appropriate measures to address the general conditions in society that may give rise to direct threats to life or prevent individuals from enjoying their right to life with dignity. These general conditions may include high levels of criminal and gun violence, [Footnote 95] pervasive traffic and industrial accidents, [Footnote 96] degradation of the environment, [Footnote 97], deprivation of land, territories and resources of indigenous peoples, [Footnote 98] the prevalence of life threatening diseases, such as AIDS, tuberculosis or malaria, [Footnote 99] extensive substance abuse, widespread hunger and malnutrition and extreme poverty and homelessness. [Footnote 100] The measures called for addressing adequate conditions for protecting the right to life include, where necessary, measures designed to ensure access without delay by individuals to essential goods and services such as food, [Footnote 101] water, shelter, health-care, [Footnote 102] electricity and sanitation, and other measures designed to promote and facilitate adequate general conditions such as the bolstering of effective emergency health services, emergency response operations (including fire-fighters, ambulances and police forces) and social housing programs. States parties should also develop strategic plans for advancing the enjoyment of the right to life, which may comprise measures to fight the stigmatization associated with disabilities and diseases, including sexually transmitted diseases, which hamper access to medical care; [Footnote 103] detailed plans to promote education to non-violence; and campaigns for raising awareness of gender-based violence [Footnote 104] and harmful practices, [Footnote 105] and for improving access to medical examinations and treatments designed to reduce maternal and infant mortality. [Footnote 106] Furthermore, States parties should also develop, when necessary, contingency plans and disaster management plans designed to increase preparedness and address natural and man-made disasters, which may adversely affect enjoyment of the right to life, such as hurricanes, tsunamis, earthquakes, radio-active accidents and massive cyber-attacks resulting in disruption of essential services.

27. An important element of the protection afforded to the right to life by the Covenant is the obligation on the States parties, where they know or should have known of potentially unlawful deprivations of life, to investigate and, where appropriate, prosecute such incidents including allegations of excessive use of force with lethal consequences. [Footnote 107] The duty to investigate also arises in circumstances in which a serious risk of deprivation of life was caused by the use of potentially lethal force, even if the risk did not materialize [Footnote 108] This obligation is implicit in the obligation to protect and is reinforced by the general duty to ensure the rights recognized in the Covenant, which is articulated in article 2, paragraph 1, when read in conjunction with article 6, paragraph 1, and the duty to provide an effective remedy to victims of human rights violations [Footnote 109] and their relatives, [Footnote 110] which is articulated in article 2, paragraph 3 of the Covenant, when read in conjunction with article 6, paragraph 1. Investigations and prosecutions of potentially unlawful deprivations of life should be undertaken in accordance with relevant international standards, including the Minnesota Protocol on the Investigation of Potentially Unlawful Death (2016), and must be aimed at ensuring that those responsible are brought to justice, [Footnote 111] at promoting accountability and preventing impunity, [Footnote 112] at avoiding denial of justice [Footnote 113] and at drawing necessary lessons for revising practices and policies with a view to avoiding repeated violations. [Footnote 114] Investigations should explore, inter alia, the legal responsibility of superior officials with regard to violations of the right to life committed by their subordinates. [Footnote 115] Given the importance of the right to life, States parties must generally refrain from addressing violations of article 6 merely through administrative or disciplinary measures, and a criminal investigation is normally required, which should lead, if enough incriminating evidence is gathered, to a criminal prosecution. [Footnote 116] Immunities and amnesties provided to perpetrators of intentional killings and to their superiors, and comparable measures leading to de facto or de jure impunity, are, as a rule, incompatible with the duty to respect and ensure the right to life, and to provide victims with an effective remedy. [Footnote 117]

28. Investigations into allegations of violation of article 6 [Footnote 118] must always be independent, [Footnote 119] impartial, [Footnote 120] prompt, [Footnote 121] thorough, [Footnote 122] effective, [Footnote 123] credible [Footnote 124] and transparent, [Footnote 125] and in the event that a violation is found, full reparation must be provided, including, in view of the particular circumstances of the case, adequate measures of compensation, rehabilitation and satisfaction. [Footnote 126] States parties are also under an obligation to take steps to prevent the occurrence of similar violations in the future. [Footnote 127] Where relevant, the investigation should include an autopsy of the victim's body, [Footnote 128] whenever possible, in the presence of a representative of the victim's relatives. [Footnote 129] States parties need to take, among other things, appropriate measures to establish the truth relating to the events leading to the deprivation of life, including the reasons and legal basis for targeting certain individuals and the procedures employed by State forces before, during and after the time in which the deprivation occurred, [Footnote 130] and identifying bodies of individuals who had lost their lives. [Footnote 131] States parties should also disclose relevant details about the investigation to the victim's next of kin, [Footnote 132] allow them to present new evidence, afford them with legal standing in the investigation, [Footnote 133] and make public information about the investigative steps taken and the investigation's findings, conclusions and recommendations, [Footnote 134] subject to absolutely necessary redactions justified by a compelling need to protect the public interest or the privacy and other legal rights of directly affected individuals. States parties must also take the necessary steps to protect witnesses, victims and their relatives and persons conducting the investigation from threats, attacks and any act of retaliation. An investigation into violations of the right to life should commence when appropriate ex officio. [Footnote 135] States should support and cooperate in good faith with international mechanisms of investigation and prosecutions addressing possible violations of article 6. [Footnote 136]

29. Loss of life occurring in custody, in unnatural circumstances, creates a presumption of arbitrary deprivation of life by State authorities, which can only be rebutted on the basis of a proper investigation which establishes the State's compliance with its obligations under article 6. [Footnote 137] States parties also have a particular duty to investigate allegations of violations of article 6 whenever State authorities have used or appear to have used firearms or other potentially lethal force outside the immediate context of an armed conflict, for example, when live fire had been used against demonstrators, [Footnote 138] or when civilians were found dead in circumstances fitting a pattern of alleged violations of the right to life by State authorities. [Footnote 139]

30. The duty to respect and ensure the right to life requires States parties to refrain from deporting, extraditing or otherwise transferring individuals to countries in which there are substantial grounds for believing that a real risk exists that their right to life under article 6 of the Covenant would be violated. [Footnote 140] Such a risk must be personal in nature [Footnote 141] and cannot derive merely from the general conditions in the receiving State, except in the most extreme cases. [Footnote 142] For example, as explained in paragraph 34 below, it would be contrary to article 6 to extradite an individual from a country that abolished the death penalty to a country in which he or she may face the death penalty. [Footnote 143] Similarly, it would be inconsistent with article 6 to deport an individual to a country in which a fatwa had been issued against him by local religious authorities, without verifying that the fatwa is not likely to be followed; [Footnote 144] or to deport an individual to an extremely violent country in which he has never lived, has no social or family contacts and cannot speak the local language. [Footnote 145] In cases involving allegations of risk to the life of the removed individual emanating from the authorities of the receiving State, the situation of the removed individual and the conditions in the receiving States need to be assessed inter alia, based on the intent of the authorities of the receiving State, the pattern of conduct they have shown in similar cases, [Footnote 146] and the availability of credible and effective assurances about their intentions. When the alleged risk to life emanates from non-state actors or foreign States operating in the territory of the receiving State, credible and effective assurances for protection by the authorities of the receiving State may be sought and internal flight options could be explored. When relying upon assurances from the receiving State of treatment upon removal, the removing State should put in place adequate mechanisms for ensuring compliance with the issued assurances from the moment of removal onwards. [Footnote 147]

31. The obligation not to extradite, deport or otherwise transfer pursuant to article 6 of the Covenant may be broader than the scope of the principle of non refoulement under international refugee law, since it may also require the protection of aliens not entitled to refugee status. States parties must, however, allow all asylum seekers claiming a real risk of a violation of their right to life in the State of origin access to refugee or other individualized or group status determination procedures that could offer them protection against refoulement. [Footnote 148]

IV. Imposition of the death penalty

32. Paragraphs 2, 4, 5 and 6 of article 6 regulate the imposition of the death penalty by those countries which have not yet abolished it.

33. Paragraph 2 of article 6 strictly limits the application of the death penalty, firstly, to States parties that have not abolished the death penalty, and secondly, to the most serious crimes. Given the anomalous nature of regulating the application of the death penalty in an instrument enshrining the right to life, the contents of paragraph 2 have to be narrowly construed. [Footnote 149]

34. States parties to the Covenant that have abolished the death penalty, through amending their domestic laws, becoming parties to the Second Optional Protocol to the Covenant or adopting another international instrument obligating them to abolish the death penalty, are barred from reintroducing it. Like the Covenant, the Second Optional Protocol does not contain termination provisions and States parties cannot denounce it. Abolition of the death penalty is therefore legally irrevocable. Furthermore, States parties may not transform an offence, which upon ratification of the Covenant, or at any time thereafter, did not entail the death penalty, into a capital offence. Nor can they remove legal conditions from an existing offence with the result of permitting the imposition of the death penalty in circumstances in which it was not possible to impose it before. States parties that abolished the death penalty cannot deport, extradite or otherwise transfer persons to a country in which they are facing criminal charges that carry the death penalty, unless credible and effective assurances against the imposition of the death penalty have been obtained. [Footnote 150] In the same vein, the obligation not to reintroduce the death penalty for any specific crime requires States parties not to deport, extradite or otherwise transfer an individual to a country in which he or she is expected to stand trial for a capital offence, if the same offence does not carry the death penalty in the removing State, unless credible and effective assurances against exposing the individual to the death penalty have been obtained.

35. The term “the most serious crimes” must be read restrictively [Footnote 151] and appertain only to crimes of extreme gravity, [Footnote 152] involving intentional killing. [Footnote 153] Crimes not resulting directly and intentionally in death, [Footnote 154] such as attempted murder, [Footnote 155] corruption and other economic and political crimes, [Footnote 156] armed robbery, [Footnote 157] piracy, [Footnote 158] abduction, [Footnote 159] drug [Footnote 160] and sexual offences, although serious in nature, can never serve as the basis, within the framework of article 6, for the imposition of the death penalty. In the same vein, a limited degree of involvement or of complicity in the commission of even the most serious crimes, such as providing the physical means for the commission of murder, cannot justify the imposition of the death penalty. States parties are under an obligation to review their criminal laws so as to ensure that the death penalty is not imposed for crimes which do not qualify as the most serious crimes. [Footnote 161] They should also revoke death sentences issued for crimes not qualifying as the most serious crimes and pursue the necessary legal procedures to re-sentence those convicted for such crimes.

36. Under no circumstances can the death penalty ever be applied as a sanction against conduct whose very criminalization violates the Covenant, including adultery, homosexuality, apostasy, [Footnote 162] establishing political opposition groups, [Footnote 163] or offending a head of state. [Footnote 164] States parties that retain the death penalty for such offences commit a violation of their obligations under article 6 read alone and in conjunction with article 2, paragraph 2 of the Covenant, as well as of other provisions of the Covenant.

37. In all cases involving the application of the death penalty, the personal circumstances of the offender and the particular circumstances of the offence, including its specific attenuating elements [Footnote 165] must be considered by the sentencing court. Hence, mandatory death sentences that leave domestic courts with no discretion on whether or not to designate the offence as a crime entailing the death penalty, and on whether or not to issue the death sentence in the particular circumstances of the offender, are arbitrary in nature. [Footnote 166] The availability of a right to seek pardon or commutation on the basis of the special circumstances of the case or the accused is not an adequate substitute for the need for judicial discretion in the application of the death penalty. [Footnote 167]

38. Article 6, paragraph 2 also requires States parties to ensure that any death sentence would be “in accordance with the law in force at the time of the commission of the crime”. This application of the principle of legality complements and reaffirms the application of the principle of nulla poena sine lege found in article 15, paragraph 1 of the Covenant. As a result, the death penalty can never be imposed, if it was not provided by law for the offence at the time of its commission. Nor can the imposition of the death penalty be based on vaguely defined criminal provisions, [Footnote 168] whose application to the convicted individual would depend on subjective or discretionary considerations [Footnote 169] the application of which is not reasonably foreseeable. [Footnote 170] On the other hand, the abolition of the death penalty should apply retroactively to individuals charged or convicted of a capital offence in accordance with the retroactive leniency (lex mitior) principle, which finds partial expression in the third sentence of article 15, paragraph 1, requiring States parties to grant offenders the benefit of lighter penalties adopted after the commission of the offence. The retroactive application of the abolition of the death penalty to all individuals charged or convicted of a capital crime also derives from the fact that the need for applying the death penalty cannot be justified once it had been abolished.

39. Article 6, paragraph 3 reminds all States parties who are also parties to the Genocide Convention of their obligations to prevent and punish the crime of genocide, which include the obligation to prevent and punish all deprivations of life, which constitute part of a crime of genocide. Under no circumstances can the death penalty be imposed as part of a policy of genocide against members of a national, ethnical, racial or religious group.

40. States parties that have not abolished the death penalty must respect article 7 of the Covenant, which bars certain methods of execution. Failure to respect article 7 would inevitably render the execution arbitrary in nature and thus also in violation of article 6. The Committee has already opined that stoning, [Footnote 171] injection of untested lethal drugs, [Footnote 172] gas chambers, [Footnote 173] burning and burying alive, [Footnote 174] and public executions, [Footnote 175] are contrary to article 7. For similar reasons, other painful and humiliating methods of execution are also unlawful under the Covenant. Failure to provide individuals on death row with timely notification about the date of their execution constitutes, as a rule, a form of ill-treatment, which renders the subsequent execution contrary to articles 7 of the Covenant. [Footnote 176] Extreme delays in the implementation of a death penalty sentence, which exceed any reasonable period of time necessary to exhaust all legal remedies, [Footnote 177] may also entail the violation of article 7 of the Covenant, especially when the long time on death row exposes sentenced persons to harsh [Footnote 178] or stressful conditions, including, solitary confinement, [Footnote 179] and when they are particularly vulnerable due to factors such as age, health or mental state. [Footnote 180]

41. Violation of the fair trial guarantees provided for in article 14 of the Covenant in proceedings resulting in the imposition of the death penalty would render the sentence arbitrary in nature, and in violation of article 6 of the Covenant. [Footnote 181] Such violations might involve the use of forced confessions; [Footnote 182] inability of the accused to question relevant witnesses; [Footnote 183] lack of effective representation involving confidential attorney-client meetings during all stages of the criminal proceedings, [Footnote 184] including during criminal interrogation, [Footnote 185] preliminary hearings, [Footnote 186] trial [Footnote 187] and appeal [Footnote 188]; failure to respect the presumption of innocence which may manifest itself in the accused being placed in a cage or handcuffed during the trial; [Footnote 189] lack of an effective right of appeal; [Footnote 190] lack of adequate time and facilities for the preparation of the defense, including inability to access legal documents essential for conducting the legal defense or appeal, such as access to official prosecutorial applications to the court, [Footnote 191] the court's judgment [Footnote 192] or the trial transcript; lack of suitable interpretation; [Footnote 193] failure to provide accessible documents and procedural accommodation for persons with disabilities; excessive and unjustified delays in the trial [Footnote 194] or the appeal process; [Footnote 195] and general lack of fairness of the criminal process, [Footnote 196] or lack of independence or impartiality of the trial or appeal court.

42. Other serious procedural flaws, not explicitly covered by article 14 of the Covenant, may nonetheless render the imposition of the death penalty contrary to article 6. For example, a failure to promptly inform detained foreign nationals of their right to consular notification pursuant to the Vienna Convention on Consular Relations resulting in the imposition of the death penalty, [Footnote 197] and failure to afford individuals about to be deported to a country in which their lives are claimed to be at real risk with the opportunity to avail themselves of available appeal procedures [Footnote 198] would violate article 6, paragraph 1 of the Covenant.

43. The execution of sentenced persons whose guilt has not been established beyond reasonable doubt also constitutes an arbitrary deprivation of life. States parties must therefore take all feasible measures in order to avoid wrongful convictions in death penalty cases, [Footnote 199] to review procedural barriers to reconsideration of convictions and to re-examine past convictions on the basis of new evidence, including new DNA evidence. States parties should also consider the implications for the evaluation of evidence presented in capital cases of new reliable studies, including studies suggesting the prevalence of false confessions and the unreliability of eyewitness testimony.

44. The death penalty must not be imposed in a discriminatory manner contrary to the requirements of articles 2(1) and 26 of the Covenant. Data suggesting that members of religious, racial or ethnic minorities, indigent persons or foreign nationals are disproportionately likely to face the death penalty may indicate an unequal application of the death penalty, which raises concerns under article 2(1) read in conjunction with article 6, as well as under article 26. [Footnote 200]

45. According to the last sentence of article 6, paragraph 2, the death penalty can only be carried out pursuant to a judgment of a competent court. Such a court must be established by law within the judiciary, be independent of the executive and legislative branches and impartial. [Footnote 201] It should be established before the commission of the offence. As a rule, civilians must not be tried for capital crimes before military tribunals [Footnote 202] and military personnel can only be tried for offences carrying the death penalty before a tribunal affording all fair trial guarantees. Furthermore, the Committee does not consider courts of customary justice as judicial institutions offering sufficient fair trial guarantees that would enable them to try capital crimes. [Footnote 203] The issuance of a death penalty without any trial, for example in the form of a religious edict [Footnote 204] or military order which the State plans to carry out or allows to be carried out, violates both article 6 and 14 of the Covenant.

46. Any penalty of death can only be carried out pursuant to a final judgment, after an opportunity to resort to all judicial appeal procedures has been provided to the sentenced person, and after petitions to all other available non-judicial avenues have been resolved, including supervisory review by prosecutors or courts, and consideration of requests for official or private pardon. Furthermore, death sentences must not be carried out as long as international interim measures requiring a stay of execution are in place. Such interim measures are designed to allow review of the sentence before, international courts, human rights courts and commissions, and international monitoring bodies, such as the UN Treaty Bodies. Failure to implement such interim measures is incompatible with the obligation to respect in good faith the procedures established under the specific treaties governing the work of the relevant international bodies. [Footnote 205]

47. States parties are required pursuant to Article 6, paragraph 4, to allow individuals sentenced to death to seek pardon or commutation, to ensure that amnesties, pardons and commutation can be granted to them in appropriate circumstances, and to ensure that sentences are not carried out before requests for pardon or commutation have been meaningfully considered and conclusively decided upon according to applicable procedures. [Footnote 206] No category of sentenced persons can be a priori excluded from such measures of relief, nor should the conditions for attainment of relief be ineffective, unnecessarily burdensome, discriminatory in nature or applied in an arbitrary manner. [Footnote 207] Article 6, paragraph 4 does not prescribe a particular procedure for the exercise of the right to seek pardon or commutation and States parties consequently retain discretion in spelling out the relevant procedures. [Footnote 208] Still, such procedures should be specified in domestic legislation, [Footnote 209] and they should not afford the families of crime victims a preponderant role in determining whether the death sentence should be carried out. [Footnote 210] Furthermore, pardon or commutation procedures must offer certain essential guarantees, including certainty about the processes followed and the substantive criteria applied; a right for individuals sentenced to death to initiate pardon or commutation procedures and to make representations about their personal or other relevant circumstances; a right to be informed in advanced when the request will be considered; and a right to be informed promptly about the outcome of the procedure.[Footnote 211]

48. Article 6, paragraph 5 prohibits imposing the death penalty for crimes committed by persons below the age of 18 at the time of the offence. [Footnote 212] This necessarily implies that such persons can never face the death penalty for that offence, regardless of their age at the time of sentencing or at the time foreseen for carrying out the sentence. [Footnote 213] If there is no reliable and conclusive proof that the person was not below the age of 18 at the time in which the crime was committed, he or she will have the right to the benefit of the doubt and the death penalty cannot be imposed. [Footnote 214] Article 6, paragraph 5 also prohibits the carrying out the death penalty on pregnant women.

49. States parties must refrain from imposing the death penalty on individuals who face special barriers in defending themselves on an equal basis with others, such as persons whose serious psycho-social and intellectual disabilities impeded their effective defense, [Footnote 215] and on persons that have limited moral culpability. They should also refrain from executing persons that have diminished ability to understand the reasons for their sentence, and persons whose execution would be exceptionally cruel or would lead to exceptionally harsh results for them and their families, such as persons at an advanced age [Footnote 216], parents to very young or dependent children, and individuals who have suffered in the past serious human rights violations. [Footnote 217]

50. Article 6, paragraph 6 reaffirms the position that States parties that are not yet totally abolitionist should be on an irrevocable path towards complete eradication of the death penalty, de facto and de jure, in the foreseeable future. The death penalty cannot be reconciled with full respect for the right to life, and abolition of the death penalty is both desirable [Footnote 218] and necessary for the enhancement of human dignity and progressive development of human rights. [Footnote 219] It is contrary to the object and purpose of article 6 for States parties to take steps to increase de facto the rate and extent in which they resort to the death penalty, [Footnote 220] or to reduce the number of pardons and commutations they grant.

51. Although the allusion to the conditions for application of the death penalty in article 6, paragraph 2 suggests that when drafting the Covenant the States parties did not universally regard the death penalty as a cruel, inhuman or degrading punishment per se, [Footnote 221] subsequent agreements by the States parties or subsequent practice establishing such agreements, may ultimately lead to the conclusion that the death penalty is contrary to article 7 of the Covenant under all circumstances. [Footnote 222] The increasing number of States parties to the Second Optional Protocol, as well as by other international instruments prohibiting the imposition or carrying out of the death penalty, and the growing number of non-abolitionist States that have nonetheless introduced a de facto moratorium on the exercise of the death penalty, suggest that considerable progress may have been made towards establishing an agreement among the States parties to consider the death penalty as a cruel, inhuman or degrading form of punishment. [Footnote 223] Such a legal development is consistent with the pro-abolitionist sprit of the Covenant, which manifests itself, inter alia, in the texts of article 6, paragraph 6 and the Second Optional Protocol.

V. Relationship of article 6 with other articles of the Covenant and other legal regimes

52. The standards and guarantees of article 6 both overlap and interact with other provisions of the Covenant. Some forms of conduct simultaneously violate both article 6 and another article. For example, applying the death penalty in response to a crime not constituting a most serious crime, [Footnote 224] would violate both article 6, paragraph 2 and, in light of the extreme nature of the punishment, also article 7. [Footnote 225] At other times, the contents of article 6, paragraph 1, are informed by the contents of other articles. For example, application of the death penalty may amount to an arbitrary deprivation of life under article 6 by virtue of the fact that it represents a punishment for exercising freedom of expression, in violation of article 19. [Footnote 226]

53. Article 6 also reinforces the obligations of States parties under the Covenant and the Optional Protocol to protect individuals against reprisals for promoting and striving to protect and realize human rights, including through cooperation or communication with the Committee. [Footnote 227] States parties must take the necessary measures to respond to death threats and to provide adequate protection to human rights defenders, [Footnote 228] including the creation and maintenance of a safe and enabling environment for defending human rights.

54. Torture and ill-treatment, which may seriously affect the physical and mental health of the mistreated individual could also generate the risk of deprivation of life. Furthermore, criminal convictions resulting in the death penalty, which are based on information procured by torture or cruel, inhuman or degrading treatment of interrogated persons, would violate articles 7 and 14, paragraph 3(g) of the Covenant, as well as article 6. [Footnote 229]

55. Returning individuals to countries where there are substantial grounds for believing that they face a real risk to their lives violates articles 6 and 7 of the Covenant. [Footnote 230] In addition, making an individual sentenced to death believe that the sentence was commuted only to inform him later that it was not, [Footnote 231] and placing an individual on death row pursuant to a death sentence that is void ab initio, [Footnote 232] would run contrary to both articles 6 and 7.

56. The arbitrary deprivation of life of an individual may cause his or her relatives mental suffering, which could amount to a violation of their own rights under article 7 of the Covenant. Furthermore, even when the deprivation of life is not arbitrary, failure to provide relatives with information on the circumstances of the death of an individual may violate their rights under article 7, [Footnote 233] as could failure to inform them of the location of the body, [Footnote 234] and, where the death penalty is applied, of the date in which the carrying out of the death penalty is anticipated. [Footnote 235] Relatives of individuals deprived of their life by the State must be able to receive the remains, if they so wish. [Footnote 236]

57. The right to life guaranteed by article 6 of the Covenant, including the right to protection of life under article 6, paragraph 1, may overlap with the right to security of person guaranteed by article 9, paragraph 1. Extreme forms of arbitrary detention that are themselves life-threatening, in particular enforced disappearances, violate the right to personal liberty and personal security and are incompatible with the right to life. [Footnote 237] Failure to respect the procedural guarantees found in article 9, paragraphs 3 and 4, designed inter alia to prevent disappearances, could also result in a violation of article 6. [Footnote 238]

58. Enforced disappearance constitutes a unique and integrated series of acts and omissions representing a grave threat to life. [Footnote 239] The deprivation of liberty, followed by a refusal to acknowledge that deprivation of liberty or by concealment of the fate of the disappeared person, in effect removes that person from the protection of the law and places his or her life at serious and constant risk, for which the State is accountable. [Footnote 240] It thus results in a violation of the right to life as well as other rights recognized in the Covenant, in particular, article 7 (prohibition of torture or cruel, inhuman or degrading treatment or punishment), article 9 (liberty and security of persons), and article 16 (right to recognition of a person before the law). States parties must take adequate measures to prevent the enforced disappearance of individuals, and conduct an effective and speedy inquiry to establish the fate and whereabouts of persons who may have been subject to enforced disappearance. States parties should also ensure that the enforced disappearance of persons is punished with appropriate criminal sanctions and introduce prompt and effective procedures to investigate cases of disappearances thoroughly, by independent and impartial bodies [Footnote 241] that operate, as a rule, within the ordinary criminal justice system. They should bring to justice the perpetrators of such acts and omissions and ensure that victims of enforced disappearance and their relatives are informed about the outcome of the investigation and are provided with full reparation. [Footnote 242] Under no circumstances should families of victims of enforced disappearance be obliged to declare them dead in order to be eligible for reparation. [Footnote 243] States parties should also provide families of victims of disappeared persons with means to regularize their legal status in relation to the disappeared persons after an appropriate period of time. [Footnote 244]

59. A particular connection exists between article 6 and article 20, which prohibits any propaganda for war and certain forms of advocacy constituting incitement to discrimination, hostility or violence. Failure to comply with these obligations under article 20, may also constitute a failure to take the necessary measures to protect the right to life under article 6. [Footnote 245]

60. Article 24, paragraph 1, of the Covenant entitles every child “to such measures of protection as are required by his status as a minor on the part of his family, society and the State.” This article requires adoption of special measures designed to protect the life of every child, in addition to the general measures required by article 6 for protecting the lives of all individuals. [Footnote 246] When taking special measures of protection, States parties should be guided by the best interests of the child, [Footnote 247] by the need to ensure the survival and development of all children, [Footnote 248] and their well-being. [Footnote 249]

61. The right to life must be respected and ensured without distinction of any kind, such as race, color, sex, language, religion, political or other opinion, national or social origin, property, birth, or any other status, including caste, [Footnote 250] ethnicity, membership of an indigenous group, sexual orientation or gender identity, [Footnote 251] disability, [Footnote 252] socio-economic status, [Footnote 253] albinism [Footnote 254] and age. [Footnote 255] Legal protections for the right to life must apply equally to all individuals and provide them with effective guarantees against all forms of discrimination, including multiple and intersectional forms of discrimination. [Footnote 256] Any deprivation of life based on discrimination in law or fact is ipso facto arbitrary in nature. Femicide, which constitutes an extreme form of gender-based violence that is directed against girls and women, is a particularly grave form of assault on the right to life. [Footnote 257]

62. Environmental degradation, climate change and unsustainable development constitute some of the most pressing and serious threats to the ability of present and future generations to enjoy the right to life. [Footnote 258] Obligations of States parties under international environmental law should thus inform the contents of article 6 of the Covenant, and the obligation of States parties to respect and ensure the right to life should also inform their relevant obligations under international environmental law. [Footnote 259] Implementation of the obligation to respect and ensure the right to life, and in particular life with dignity, depends, inter alia, on measures taken by States parties to preserve the environment and protect it against harm, pollution and climate change caused by public and private actors. States parties should therefore ensure sustainable use of natural resources, develop and implement substantive environmental standards, conduct environmental impact assessments and consult with relevant States about activities likely to have a significant impact on the environment, provide notification to other States concerned about natural disasters and emergencies and cooperate with them, provide appropriate access to information on environmental hazards and pay due regard to the precautionary approach. [Footnote 260]

63. In light of article 2, paragraph 1, of the Covenant, a State party has an obligation to respect and to ensure the rights under article 6 of all persons who are within its territory and all persons subject to its jurisdiction, that is, all persons over whose enjoyment of the right to life it exercises power or effective control. [Footnote 261] This includes persons located outside any territory effectively controlled by the State, whose right to life is nonetheless impacted by its military or other activities in a direct and reasonably foreseeable manner. [Footnote 262] States also have obligations under international law not to aid or assist activities undertaken by other States and non-State actors that violate the right to life. [Footnote 263] Furthermore, States parties must respect and protect the lives of individuals located in places, which are under their effective control, such as occupied territories, and in territories over which they have assumed an international obligation to apply the Covenant. States parties are also required to respect and protect the lives of all individuals located on marine vessels or aircrafts registered by them or flying their flag, and of those individuals who find themselves in a situation of distress at sea, in accordance with their international obligations on rescue at sea. [Footnote 264] Given that the deprivation of liberty brings a person within a State's effective control, States parties must respect and protect the right to life of all individuals arrested or detained by them, even if held outside their territory. [Footnote 265]

64. Like the rest of the Covenant, article 6 continues to apply also in situations of armed conflict to which the rules of international humanitarian law are applicable, including to the conduct of hostilities. [Footnote 266] While rules of international humanitarian law may be relevant for the interpretation and application of article 6 when the situation calls for their application, both spheres of law are complementary, not mutually exclusive. [Footnote 267] Use of lethal force consistent with international humanitarian law and other applicable international law norms is, in general, not arbitrary. By contrast, practices inconsistent with international humanitarian law, entailing a risk to the lives of civilians and other persons protected by international humanitarian law, including the targeting of civilians, civilian objects and objects indispensable to the survival of the civilian population, indiscriminate attacks, failure to apply the principles of precaution and proportionality, and the use of human shields, would also violate article 6 of the Covenant. [Footnote 268] States parties should, in general, disclose the criteria for attacking with lethal force individuals or objects whose targeting is expected to result in deprivation of life, including the legal basis for specific attacks, the process of identification of military targets and combatants or persons taking a direct part in hostilities, the circumstances in which relevant means and methods of warfare have been used, [Footnote 269] and whether less harmful alternatives were considered. They must also investigate alleged or suspected violations of article 6 in situations of armed conflict in accordance with the relevant international standards. [Footnote 270]

65. States parties engaged in the deployment, use, sale or purchase of existing weapons and in the study, development, acquisition or adoption of weapons, and means or methods of warfare, must always consider their impact on the right to life. [Footnote 271] For example, the development of autonomous weapon systems lacking in human compassion and judgement raises difficult legal and ethical questions concerning the right to life, including questions relating to legal responsibility for their use. The Committee is therefore of the view that such weapon systems should not be developed and put into operation, either in times of war or in times of peace, unless it has been established that their use conforms with article 6 and other relevant norms of international law. [Footnote 272]

66. The threat or use of weapons of mass destruction, in particular nuclear weapons, which are indiscriminate in effect and are of a nature to cause destruction of human life on a catastrophic scale is incompatible with respect for the right to life and may amount to a crime under international law. States parties must take all necessary measures to stop the proliferation of weapons of mass destruction, including measures to prevent their acquisition by non-state actors, to refrain from developing, producing, testing, acquiring, stockpiling, selling, transferring and using them, to destroy existing stockpiles, and to take adequate measures of protection against accidental use, all in accordance with their international obligations. [Footnote 273] They must also respect their international obligations to pursue in good faith negotiations in order to achieve the aim of nuclear disarmament under strict and effective international control. [Footnote 274] and to afford adequate reparation to victims whose right to life has been or is being adversely affected by the testing or use of weapons of mass destruction, in accordance with principles of international responsibility. [Footnote 275]

67. Article 6 is included in the list of non-derogable rights of article 4, paragraph 2 of the Covenant. Hence, the guarantees against arbitrary deprivation of life contained in article 6 continue to apply in all circumstances, including in situations of armed conflict and other public emergencies. [Footnote 276] The existence and nature of a public emergency which threatens the life of the nation may, however, be relevant to a determination of whether a particular act or omission leading to deprivation of life is arbitrary and to a determination of the scope of the positive measures that States parties must undertake. Although some Covenant rights other than the right to life may be subject to derogation, derogable rights which support the application of article 6 must not be diminished by measures of derogation. [Footnote 277] Such rights include procedural guarantees, such as the right to fair trial in death penalty cases, and accessible and effective measures to vindicate rights, such as the duty to take appropriate measures to investigate, prosecute, punish and remedy violations of the right to life.

68. Reservations with respect to the peremptory and non-derogable obligations set out in article 6 are incompatible with the object and purpose of the Covenant. In particular, no reservation to the prohibition against arbitrary deprivation of life of persons and to the strict limits provided in Article 6 with respect to the application of the death penalty is permitted. [Footnote 278]

69. Wars and other acts of mass violence continue to be a scourge of humanity resulting in the loss of lives of many thousands of lives every year. [Footnote 279] Efforts to avert the risks of war, and any other armed conflict, and to strengthen international peace and security, are among the most important safeguards for the right to life. [Footnote 280]

70. States parties engaged in acts of aggression as defined in international law, resulting in deprivation of life, violate ipso facto article 6 of the Covenant. At the same time, all States are reminded of their responsibility as members of the international community to protect lives and to oppose widespread or systematic attacks on the right to life, [Footnote 281] including acts of aggression, international terrorism, genocide, crimes against humanity and war crimes, while respecting all of their obligations under international law. States parties that fail to take all reasonable measures to settle their international disputes by peaceful means might fall short of complying with their positive obligation to ensure the right to life.
