In July 2017 the UN Human Rights Committee finalised the first reading of its Draft General Comment no 36 on article 6 (right to life) of the International Covenant on Civil and Political Rights (ICCPR). All stakeholders, including Member States, other UN and regional human rights mechanisms, National Human Rights Institutions, NGOs, research institutions, and academics were invited to provide their observations by 6 October 2017. In November 2017, the UN Human rights Committee started the second reading of its Draft General Comment. This post aims to provide some preliminary remarks on the UK Government submissions, which should be interpreted while bearing in mind a significant difference between the UK position and the Draft Comment: according to the former, indeed, there is no hierarchical relationship among rights, and the right to life is not the ‘supreme’ right among all others, as it is, conversely, for the latter. This post will focus on three specific areas of concern for the UK: the desirability of an international treaty banning any Lethal Autonomous Weapons Systems (LAWS), the relationship between the regimes of international human rights and international humanitarian law, the linkage between the right to life and any act of aggression.
On the ban of any Lethal Autonomous Weapons Systems (LAWS)
Starting from the assumption that in the development of new kind of weapons Sates should always consider the possible implications of such weapons for the right to life, the UN Human Rights Committee, at paragraph 12 of its Draft General Comment, holds that ‘the development for use in military operations of new lethal autonomous robotics 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 therefore concludes that this kind of weapons should not be developed or put in operation; neither in time of war or peace. The UK Government, on the contrary, considers that since it is unclear whether these weapons would ever be developed, it would be pointless to have an international agreement banning them pre-emptively. Thus, the UK ‘strongly urges’ to delete the part relating to the need to avoid the development and/or ban of any LAWS. Yet, this conclusion seems to lie more on the non-existence of such weapons, which furthermore still lack of a definition, than on their legality under international law. In this respect, the UK aligns its positions to the other EU member states. As Veronique Caruana has pointed out, however, in the future we might witness «the continued development of a “class of systems capable of selecting targets and initiating the use of potentially lethal force without the deliberate and specific consideration of humans”». Considering that the issue has been broadly debated among governments, scholars, and NGOs, the prospect of developing such weapons seems in fact to be a concrete possibility.
On the relationship between International Humanitarian Law and Human Rights Law
According to paragraph 67 of the Draft General Comment, the Covenant as a whole continues to apply in time of armed conflict, as the two regimes of Human Rights Law and International Humanitarian Law (IHL) are complementary, rather than mutually exclusive. The UN Human Rights Committee concludes that during an armed conflict States have therefore an obligation to disclose, inter alia, ‘whether non-lethal alternatives for attaining the same military objective were considered. They must also investigate allegations of violations of article 6 in situations of armed conflict in accordance with the relevant international standards.’ In respect of both these points the UK Government submits that International Humanitarian Law is lex specialis applicable during an armed conflict, and under this regime there is no rule imposing upon states an obligation to consider whether a non-lethal means was available. Moreover, while it is admitted that States have an obligation to investigate breaches of IHL in accordance to international legal standards, they reject the submission that in time of an armed conflict such obligation to investigate would also apply to any violation of article 6 ICCPR. This would be somehow equal to interpret the two regimes of International Humanitarian Law and Human Rights Law as mutually exclusive, and might have serious implications when it comes to the implementation of the principles of proportionality and necessity, which are much more stringent within the context of the International Human Rights regime. This would also place the UK far from the interpretation given by the European Court of Human Rights (ECtHR) of the positive procedural obligations stemming from article 2 (Right to life) of the European Convention of Human Rights (ECHR). The ECtHR has indeed ‘held that the procedural obligation under Article 2 continues to apply in difficult security conditions, including in a context of armed conflict’. In the opinion of the Strasbourg Court these obligations include a duty to carry out an effective investigation, which might comprise criminal procedures, but also inquiries on state responsibility.  This might apply to cases of death of civilians as well as soldiers, and can also require the investigators to ‘establish basic facts about the use of indiscriminate weapons’, when the former were ‘crucial for the assessment of the causal link between their use and the casualties’. The Court has in fact found that the ‘use of explosive and indiscriminate weapons, with the attendant risk for human life, cannot be regarded as absolutely necessary’. 
On the implications for the right to life as a result of acts of aggression
The last two paragraphs of the Draft Comment no 36 are dedicated to the implications for the right to life in case of war, and even more specifically, in the event of the commission of any act of aggression contrary to the UN Charter. Paragraph 71, notably provides as follows: ‘States parties engaged in acts of aggression contrary to the United Nations Charter violate ipso facto article 6 of the Covenant. Moreover, States parties that fail to take all reasonable measures to settle their international disputes by peaceful means so as to avoid resort to the use of force do not comply in full with their positive obligation to ensure the right to life.’
The UK, at paragraph 34 of its observations, comments by stating: ‘We are rather surprised at the inclusion of paragraphs 70 and 71; these appear to be better suited to an aspirational document rather than a General Comment. We do not consider that the content is helpful, nor that it is within the Committee’s mandate.’ Thus, in the UK Government’s opinion the loss of lives resulting from the usage of an unlawful means, that is, in this specific case, an illegal war or an act of aggression, would not fall within the jurisdiction of the UN Human Rights Committee. It is however unclear where this limitation should be inferred from. In Europe, the Strasbourg Court has kept holding that article 2 ECHR (right to life) cannot be subject to any derogation, under article 15 ECHR, if not with regard to ‘lawful acts of war’. A contrario, one might argue that all other means should be considered as unlawful and cannot find any justification under the ECHR. Moreover, it rests to be shown how, under which circumstances and towards whom such paragraphs might ever end up being in any way ‘unhelpful’.
The UN Human Rights Committee is currently at its second reading of the Draft General Comment no 36 on article 6 ICCPR (right to life). Between its first and second reading, the Committee invited all stakeholders to submit their observations. This post focused on the UK position on article 6 ICCPR, which significantly departs from the Draft Comment in many aspects. First, the UK while aligning itself with the position taken by all other EU member states, differs from the UN Committee’s Draft General Comment, when the Government considers it pointless to ban or refrain from developing any LAWS. In the opinion of the UK Government, in fact, these weapons have not been developed yet and a significant amount of uncertainty surrounds their future characteristics, effects and even definition. Second, while the UN Human Rights Committee considers the Covenant to apply during an armed conflict, the UK sees the regime of International Humanitarian Law as lex specialis and deems there exists no positive obligation to investigate any violation of article 6 ICCPR. Nor do they think they have any obligation to disclose whether any non-lethal means was available. This might have huge implications on the implementation of the principles of necessity and proportionality, which refer to different standards, depending on which regime, i.e., Human Rights Law or International Humanitarian Law, is indeed applicable. In this respect, the UK would put itself far from the stance of the ECtHR’s case law. Third, the UK considers the UN Human Rights Committee went beyond its jurisdictions, when it inserted paragraphs 70-71 in the Draft General Comment. These paragraphs concern the casual relation between any unlawful armed conflicts, or more specifically any acts of aggression contrary to the UN Charter, and an automatic violation of article 6 ICCPR. However, when it comes to any possible implications for the right to life, it is unclear where the UK could infer any limitation of the UN Human Rights Committee’s ratione materiae jurisdiction. Moreover, it rests to be shown how, and especially under which circumstances and towards whom, such paragraphs could be in any way ‘unhelpful’. In sum, the UK position on the right to life differs significantly from the UN Committee, and in many occasions this would be equal to a less comprehensive protection of the individuals’ right to life. This might find an explanation in the UK vision of human rights, which according to the Government’s observations relating to the Draft General Comment no 36, would not have any hierarchical relationship, so that the right to life would not be seen as ‘the supreme’ among all other rights any more.
