6 Mampilly has found that NSAGs regularly engage in governance activities, such as “providing security from violence; developing educational and health facilities; establishing a system of food production and distribution; allocating land and other resources to provide opportunities for civilians to engage in livelihood activities (agriculture, small business, etc.); providing shelter to the displaced; regulating market transactions; taxation of civilians and commercial actors; resolving civil disputes; and addressing other social problems that commonly accompany situations of internal war”.

18 For a comprehensive analysis of what the “organization” criterion for an NSAG under IHL means, see T. Rodenhäuser, above note 5, pp. 19–120.

19 While control over territory is one element that is required for the applicability of Additional Protocol II (AP II, see Art. 1(2)), other IHL obligations – most notably those under customary IHL – are the same for all NSAGs, irrespective of whether they exercise “stable” control over territory, whether such control is exclusive, or what governance capacities a group may have. Such considerations have, however, been mentioned in discussions on whether NSAGs might be held accountable under IHRL.

22 ICRC Commentary on GC I, above note 12, para. 232. While the fact that NSAGs are bound by IHL is broadly accepted, academic debate continues on which legal theory may explain the binding effect of IHL on NSAGs. For recent examinations of the issue, see S. Sivakumaran, above note 13, pp. 238–242; Murray, Daragh, “How International Humanitarian Law Treaties Bind Non-State Armed Groups”, Journal of Conflict and Security Law, Vol. 20, No. 1, 2015CrossRefGoogle Scholar.

23 M. Sassòli, above note 13, p. 269. While AP II mentions the fact that “organized armed groups” might “exercise such control over a part of [a High Contracting Party's] territory as to enable them to carry out sustained and concerted military operations and to implement this Protocol” (Art. 1(1)), the Protocol does not contain rules on the administration of such territories, other than fundamental guarantees protecting persons who do not take a direct part in or who have ceased to take part in hostilities.

Similarly, Sassòli finds that IHL applicable in NIAC has a “certain utility for people who find themselves in territory administered by an armed group by protecting them against torture, summary executions, starvation as a method of war, looting, enforced disappearance or the destruction of their cultural heritage”. M. Sassòli, above note 13, p. 269.

29 See, for instance, Katharine Fortin, The Accountability of Armed Groups under Human Rights Law, Oxford University Press, Oxford, 2017, pp. 47–51. As Heffes points out, proponents of human rights obligations of NSAGs have argued that there are two “protection gaps” which call for such obligations. First, there is arguably a “lack of IHL rules regulating certain issues of daily life” (this will be examined further in the section below entitled “IHL Provides Important – but Limited – Rules”); and second, “issues taking place in the everyday life of individuals with no nexus to the armed conflict fall outside the scope of IHL”.

IHL of NIAC may also apply in certain areas outside the territory of the State on whose territory the conflict takes place, for instance in the context of spill-overs.

38 ICTY, Tadić, above note 35, para. 70. Two elements are commonly examined in this context: “The armed confrontation must reach a minimum level of intensity and the parties involved in the conflict must show a minimum of organisation.” ICRC, How is the Term “Armed Conflict” Defined in International Humanitarian Law?, Opinion Paper, March 2008, p. 5.

44 ICRC Commentary on GC I, above note 12, para. 491. Going in a similar direction, Sivakumaran concludes that a NIAC would end only “when the fighting declines up until the point that it dissipates entirely”. S. Sivakumaran, above note 13, p. 253. The ICRC suggests the following indicators to assess whether or not this threshold has been met: “the effective implementation of a peace agreement or ceasefire; declarations by the Parties, not contradicted by the facts on the ground, that they definitely renounce all violence; the dismantling of government special units created for the conflict; the implementation of disarmament, demobilization and/or reintegration programmes; the increasing duration of the period without hostilities; and the lifting of a state of emergency or other restrictive measures”. ICRC Commentary on GC I, above note 12, para. 495.

45 As the ICTY cautioned, if the end of IHL applicability is declared too easily, “the participants in an armed conflict may find themselves in a revolving door between applicability and non-applicability, leading to a considerable degree of legal uncertainty and confusion”.

47 Note, however, that certain rules of IHL continue to apply even after the end of a NIAC. See, for example, AP II, Art. 2(2). On the applicability of international criminal law to NSAGs, see T. Rodenhäuser, above note 5, Part 3.

48 ICRC Commentary on GC I, above note 12, para. 521. The Commentary makes reference to the ICC Elements of Crimes, which define as persons protected by common Article 3 of the Geneva Conventions: “such person or persons [who] were either hors de combat, or were civilians, medical personnel, or religious personnel taking no active part in the hostilities” (emphasis added).

This understanding can be traced back all the way to Article 44 of the Lieber Code, which prescribed severe punishment for the killing of inhabitants in an invaded country.

The notion of “nexus” is discussed further in this section.

54 As Cassese observed: “As no international rule clearly and explicitly defines the nexus under discussion, the contours and content of such nexus must be inferred from the whole spirit of IHL and international criminal law (ICL) as well as the object and purpose of the relevant international rules.” Cassese, Antonio, “The Nexus Requirement for War Crimes”, Journal of International Criminal Justice, vol. 10, no. 5, 2012, p. 1397CrossRefGoogle Scholar.

55 As the ICRC reported from the conferences of government experts preceding the actual negotiations of the Additional Protocols, some experts considered it “exaggerated to lay down the automatic application of all the Protocol provisions to the entire territory of a High Contracting Party, even though only a very small part of the country might be affected by the armed conflict”. ICRC, Draft Additional Protocols to the Geneva Conventions of August 12, 1949: Commentary, Geneva, October 1973, p. 134; see also ICRC, Conference of Government Experts on the Reaffirmation and Development of International Humanitarian Law Applicable in Armed Conflicts: Report on the Work of the Conference (Second Session, Geneva, 3 May–3 June 1972), Geneva, August 1971, p. 68.

58 Nils Melzer, Targeted Killing in International Law, Oxford University Press, Oxford, 2008, p. 143. Similarly, in an analysis of the jurisprudence of the International Military Tribunal of Nuremberg and the question of which crimes were considered to have a nexus to the Second World War, Cassese held: “There was no need to show that these civilians were up in arms against Germany or its allies, no need to show formal status of prisoners of war, and no requirement that the medical experiments were directly linked to the war efforts. The existence of the armed conflict, coupled with the fact that the medical experiments in question were carried out in unison with a persecutory plan that could not concretely have been carried out in the absence of the hostilities were sufficient to consider the conduct in question to be war crimes.” A. Cassese, above note 54, p. 1401 (emphasis in original).

59 The question of whether this understanding of the “nexus” contradicts the “equality of belligerents” principle is discussed under the heading “Caveats to a Wide Nexus Requirement” below.

This argument is further developed in Elvina Pothelet, Searching for the Nexus: A Proposal to Refine the Scope of Applicability of International Humanitarian Law and War Crimes Law, 2021 (on file with the author).

61 Official Records of the Diplomatic Conference on the Reaffirmation and Development of International Humanitarian Law applicable in Armed Conflicts, Vol. 8, CDDH/I/SR.22, Geneva, 1974–77, p. 201. In the view of Cassese, “a teleological interpretation of IHL and ICL may lead to the proper classification of the offence” (emphasis in original). Accordingly, he finds that “the aim of the whole corpus of rules of IHL is to safeguard as much as possible the life and limb of persons caught in the maelstrom of armed violence. ICL supports and enforces this aim, by providing for the prosecution and punishment of all those who, by their conduct, run counter to that aim and imperil persons involved in armed conflict”.

65 See ICRC, Protocol Additional to the Geneva Conventions of 12 August 1949, and relating to the Protection of Victims of Non-International Armed Conflicts (Protocol II): Commentary of 1987, Geneva, 1987, para. 4568, which states: “The term ‘deprived of their liberty for reasons related to the armed conflict’ is taken from Article 2 (Personal field of application), paragraph 2, of the Protocol. At this point it is appropriate to recall its far-reaching scope. … However, there must be a link between the situation of conflict and the deprivation of liberty; consequently prisoners held under normal rules of criminal law are not covered by this provision.” It is not clear what is meant by “normal rules of criminal law”.

66 Ibid., para. 4457.

67 As Bothe explains, “[r]ules concerning the punishment of war crimes are secondary rules in relation to the primary rules concerning behaviour which is prohibited in case of an armed conflict”. Michael Bothe, “War Crimes”, in Antonio Cassese, Paola Gaeta and John R. W. D. Jones (eds), The Rome Statute of the International Criminal Court: A Commentary, Oxford University Press, Oxford, 2002, p. 381. Indeed, if an act is committed as part of the “official duties” of a member of the NSAG and is found to have a nexus to a conflict, the same act will also be sufficiently linked to the conflict to bring into play IHL obligations of the NSAG.

Germain Katanga, Case No. ICC-01/04-01/07-3436-tENG, Judgement (Trial Chamber), 7 March 2014, para. 1176. Note that these elements have been criticized for being overly broad and may permit different conclusions in similar situations. See Harmen van der Wilt, “War Crimes and the Requirement of a Nexus with an Armed Conflict”, Journal of International Criminal Justice, Vol. 10, No. 5, 2012.

71 ICTY, Kunarac, above note 70, para. 59; ICTR, Rutaganda, above note 69, paras 569–570. See also ICC, Bemba, above note 70, para. 143. In the Bemba case, the ICC omitted the factor that “the victim is a member of the opposing party”.

72 As stated above, this finding is, logically, limited to issues on which IHL provides rules. As seen in the section below entitled “Do NSAGs Have Human Rights Obligations?”, there are a number of issues for which IHL does not provide any rules and for which human rights law might be relevant.

73 See ICRC Commentary on GC I, above note 12, paras 447–451; ICTY, Prosecutor v. Fatmir Limaj et al., Case No. IT-03-66, Judgment (Trial Chamber), 30 November 2005, para. 170.

74 Based on relevant case law, Cassese has argued that for a nexus to exist, “the offence must be committed to pursue the aims of the conflict or, alternatively, be carried out with a view to somehow contributing to attain the ultimate goals of a military campaign or, at a minimum, in unison with the military campaign”. A. Cassese, above note 54, p. 1397.

75 For a similar conclusion with regard to the conduct of NSAGs in Timbuktu in 2012, see ICC, Prosecutor v. Ahmad al Faqi al Mahdi, Case No. ICC-01/12-01/15-66-Conf, version publique expurgée du “Document présentant les conclusions factuelles et juridiques du Bureau du Procureur au soutien du Chef d'accusation dans l'affaire contre Ahmad al Faqi al Mahdi”, 17 December 2015, paras 258–261.

76 A nexus to the conflict might also be said to exist if the group takes control over territory and enforces pre-existing rules, such as the territorial State's criminal law. The act would still be committed by an NSAG member in the exercise of “official duties” against a person protected by IHL, and it is likely that in many cases the consolidation of territorial control – and control over the civilians living in the territory – will align with the group's military objectives. For a different view, see W. Schabas, above note 28, p. 97, arguing that “the observation that a group may be in a position to do things after it has taken power that it was not previously able to do hardly seems an adequate nexus for war crimes law to apply”.

77 While this conclusion is based on the analysis of the understanding of the nexus and indicative factors presented by criminal tribunals, it must be noted that Articles 5 and 6 of AP II do not apply to conditions of detention of persons detained for reasons unrelated to the armed conflict or to penal prosecutions of criminal offences that are not related to the conflict.

84 IHL rules and the related war crimes regime would continue to apply to those acts for which IHL defines rules and regardless of whether other bodies of international law, such as human rights law, may be said to also be relevant. This would be an approach analogous to how the law of occupation as applicable in international armed conflict would address the issue.

85 See the section entitled “Do NSAGs Have Human Rights Obligations?” below.

86 Note, however, that even in such situations a conflict nexus will exist if members of that administration capture and ill-treat a person who is suspected of spying for another party to the conflict – irrespective of who is conducting the ill-treatment.

96 A rule that does require positive steps is, for example, the obligation of all parties to armed conflicts to collect and care for the wounded and sick. See common Article 3; ICRC Customary Law Study, above note 88, Rule 109.

For more recent and comprehensive analyses of the issue, see D. Murray, above note 5; K. Fortin, above note 29; T. Rodenhäuser, above note 5; Jean-Marie Henckaerts and Cornelius Wiesener, “Human Rights Obligations of Non-State Armed Groups: An Assessment Based on Recent Practice”, in Ezequiel Heffes, Marcos D. Kotlik and Manuel J. Ventura (eds), International Humanitarian Law and Non-State Actors: Debates, Law and Practice, Asser Press, The Hague, 2020. In 2021, a group of UN human rights experts stated jointly that “at a minimum, armed non-State actors exercising either government-like functions or de facto control over territory and population must respect and protect the human rights of individuals and groups”. “Joint Statement by Independent United Nations Human Rights Experts on Human Rights Responsibilities of Armed non-State Actors”, Geneva, 25 February 2021, available at: www.ohchr.org/EN/NewsEvents/Pages/DisplayNews.aspx?NewsID=26797&LangID=E.

104 For an analysis of possible sources and legal constructs that could be invoked to argue that NSAGs have human rights obligations, see A. Clapham, above note 103; D. Murray, above note 5, pp. 167–171; K. Fortin, above note 29, pp. 273–274. See also T. Rodenhäuser, above note 5, pp. 169–177.

A/HRC/21/50, 16 August 2012, Annex II, para. 10; Human Rights Council, above note 14, para. 62; UN Human Rights, above note 34, para. 31. Indeed, only two human rights treaties address armed groups: the Optional Protocol to the Convention on the Rights of the Child on the Involvement of Children in Armed Conflict, 25 May 2000; and the African Union Convention for the Protection and Assistance of Internally Displaced Persons in Africa, 23 October 2009.

106 See “Joint Statement”, above note 103. For detailed discussions on the idea that human rights obligations devolve with territory, see T. Rodenhäuser, above note 5, pp. 173–176; K. Fortin, above note 29, pp. 275–276; D. Murray, above note 5, pp. 134–138.

107 In 2018 the International Law Commission concluded that the practice of non-State actors, including NSAGs, “is not practice that contributes to the formation, or expression, of rules of customary international law”. International Law Commission, “Draft Conclusions on Identification of Customary International Law, with Commentaries”, 2018, Conclusion 4, para. 3, para. 8 of the commentary to that conclusion. The question of whether the practice of NSAGs is relevant for the identification of customary international law has been subject to debate. See Sassòli, Marco, “Taking Armed Groups Seriously: Ways to Improve their Compliance with International Humanitarian Law”, Journal of International Humanitarian Legal Studies, vol. 1, no. 1, 2010, pp. 21–22CrossRefGoogle Scholar; Somer, Jonathan, “Jungle Justice: Passing Sentence on the Equality of Belligerents in Non-International Armed Conflict”, International Review of the Red Cross, vol. 89, no. 867, 2007, pp. 661–662CrossRefGoogle Scholar; Bellal, Annyssa and Heffes, Ezequiel, “‘Yes, I Do’: Binding Armed Non-State Actors to IHL and Human Rights Norms Through Their Consent”, Human Rights & International Legal Discourse, vol. 12, no. 1, 2018, pp. 125–126Google Scholar.

108 For a sceptical view on possible human rights obligations of NSAGs, see M. Sassòli, above note 13, pp. 270–273. Similarly, Ronen points out that “it is also difficult to locate articulations of states’ positions regarding [non-State actors’] human rights obligations”. Ronen, Yaël, “Human Rights Obligations of Territorial Non-State Actors”, Cornell International Law Journal, vol. 46, no. 1, 2013, p. 38Google Scholar. For views that NSAGs have human rights obligations as a matter of law, see J.-M. Henckaerts and C. Wiesener, above note 103, fn. 86, citing K. Fortin, above note 28, pp. 172–176; D. Murray, above note 5, pp. 120–154; A. Bellal, above note 100, pp. 26–30. In previous publications, the present author found that “practice remains somewhat unclear on the nature and scope of possible human rights obligations”, but noted that “State and human rights expert practice of addressing human rights obligations to armed groups indicates in which direction international human rights law develops”. T. Rodenhäuser, above note 5, p. 211.

109 See above notes 100–102. While these resolutions at times make reference to territorial control exercised by armed groups, this does not seem to be a condition. A rather broad approach to possible human rights obligations of armed groups is found in progressive statements by human rights experts, such as that “human rights obligations constituting peremptory international law (ius cogens) bind States, individuals and non-State collective entities, including armed groups”.

119 For instance, in 2020 the UN Working Group on Enforced or Involuntary Disappearances reported that it had started “documenting violations tantamount to enforced disappearance perpetrated by non-State actors” and that “during the reporting period, the Working Group transmitted 21 cases tantamount to enforced disappearance, namely to the Libyan National Army – Libya (4 cases); to the self-proclaimed “Donetsk People's Republic” – Ukraine (8 cases); to the de facto authorities in Sana'a – Yemen (5 cases); and to Hamas – State of Palestine (4 cases)”. Human Rights Council, Report of the Working Group on Enforced or Involuntary Disappearances, UN Doc. A/HRC/45/13, 7 August 2020, paras 23, 24. Note, however, that most human rights enforcement mechanisms, such as treaty bodies and tribunals, are currently addressing State violations of human rights, not the conduct of NSAGs.

120 On the challenge of finding a relevant reference list of human rights for different NSAGs, see T. Rodenhäuser, above note 5, pp. 177–180, 189–192, 206–208.

121 See A. Bellal, above note 100, Annex; J. Burniske, N. K. Modirzadeh and D. A. Lewis, above note 100, Annex II. Occasionally, resolutions condemn specific violations explicitly, such as violence against children and women, including child recruitment, discrimination or sexual violence, or demand protection and access for humanitarian personnel.

123 Note, however, that with regard to some issues, such as the minimum age for recruitment, IHL and IHRL address the same issue but include different standards. Compare Article 4(3)(c) of APII with the Optional Protocol to the Convention on the Rights of the Child on the Involvement of Children in Armed Conflict.

126 As the Human Rights Committee has held, “the positive obligations on States Parties to ensure [ICCPR] rights will only be fully discharged if individuals are protected by the State, not just against violations of Covenant rights by its agents, but also against acts committed by private persons or entities that would impair the enjoyment of Covenant rights in so far as they are amenable to application between private persons or entities”. Human Rights Committee, General Comment No. 31, “The Nature of the General Legal Obligation Imposed on States Parties to the Covenant”, UN Doc. CCPR/C/21/Rev.1/Add.13, 26 May 2004, para. 8.

127 However, some have cautioned that addressing human rights obligations directly to NSAGs could legitimize such groups. See UN Commission on Human Rights, Extrajudicial, Summary or Arbitrary Executions, UN Doc. E/CN.4/RES/1992/72, 5 March 1992, paras 614, 627. For discussion on this issue, see G.
