⁴ For instance, military courts may fail to be sufficiently independent from the military chain of command and therefore subject to interference; they may impose secrecy regulations or operate in closed proceedings; military judges may lack legal training or expertise on a par with that of civilian judges; see, eg, Duxbury, Alison and Groves, Matthew (eds), Military Justice in the Modern Age (Cambridge 2016)CrossRefGoogle Scholar; Dan Maurer, ‘Are Military Courts Really Just Like Civilian Criminal Courts?’ Lawfare, 13 July 2018, https://www.lawfareblog.com/are-military-courts-really-just-civilian-criminal-courts.

⁵ In Mustafa v Bulgaria, for example, the European Court of Human Rights (ECtHR) found that the military courts did not meet the requirements for a fair trial (specifically independence and impartiality) over a civilian (tried for committing a crime alongside a service member) on the ground that both the judges and jurors were members of the military, and that there was no ‘compelling’ reason to try a civilian in a military court: ECtHR, Mustafa v Bulgaria, App no 1230/17, 28 Nov 2019; see also ECtHR, Incal v Turkey, App no 22678/93, 9 June 1998. In Durand y Ugarte v Peru, the Inter-American Court of Human Rights (Inter-AmCtHR) found that military courts could not adequately investigate and punish military members for human rights violations as such crimes could not be considered to be of a ‘military’ nature and did not meet the requirements of an independent or impartial court as laid out in the American Convention on Human Rights: Case of Durand y Ugarte v Peru (2000) Inter-AmCtHR (ser C) No 68. In Castillo Petruzzi et al v Peru, it was found that military courts could not be established to supplant the jurisdiction of the ordinary courts: Case of Castillo Petruzzi et al v Peru (1999) Inter-AmCtHR, Judgment of 30 May 1999 (ser C) No 52.

In general, these critiques evaluate military trials of civilians that are not taking place in the context of armed conflict. These analyses rarely address the issue of civilians directly participating in hostilities and how that might have an impact on the competence of a military court or its legitimacy to try such civilians. Another issue that requires more attention is how civilian courts can manage the necessity of IHL expertise, a difficult and highly technical area of law; see Weill, Sharon, The Role of National Courts in Applying International Humanitarian Law (Oxford University Press 2014)CrossRefGoogle Scholar (taking a Gramscian approach in analysing the application of IHL by national courts, and instead advocating the use of international courts). It is unclear, however, whether international courts are necessarily more competent in addressing IHL issues (as is discussed below) or are freer from the politics and structural deficiencies she challenges; see, eg, Jinks, Derek, Maogoto, Jackson Nyamuya and Solomon, Solon, ‘Introducing International Humanitarian Law to Judicial and Quasi-Judicial Bodies’ in Jinks, Derek, Maogoto, Jackson Nyamuya and Solomon, Solon (eds) Applying International Humanitarian Law in Judicial and Quasi-Judicial Bodies: International and Domestic Aspects (TMC Asser Press 2014) 1, 1–2Google Scholar (noting that international courts have not always adequately addressed IHL).

³⁹ The Inter-American and European regional systems also have a considerable body of output on military courts, but they have been analysed extensively in the academic literature. In contrast, the African human rights bodies have been less a topic of focus, but no less deserving of study and analysis; see, eg, Sang (30) 2 and n 2 (commenting that examination of the African system has ‘not received as much, as detailed, or as sustained attention as that given to the same questions in the practice of other human rights treaty mechanisms’).

⁴⁰ It is important to note that almost all of the policy work of the Human Rights Council and the Commission is conducted under the auspices of the OHCHR, and the special procedures mandate holders, advisers and other rapporteurs are engaged by the OHCHR. Although this section discusses initiatives that take place under the auspices of the Council, it is the OHCHR staff, mandate holders and consultants who engage in the actual work. In some cases these individuals are appointed and approved by the member states of the Council; in others they are selected and hired by the OHCHR.

⁴¹ The Human Rights Council began operating in June 2006.

⁴² The Commission was disbanded in 2005.

⁴³ eg, Mohammed Ahmed Abu Rannat, Equality in the Administration of Justice (1969), UN Doc E/CN.4/Sub.2/296/Rev.1. In 1994 the Sub-Commission on Prevention of Discrimination and Protection of Minorities presented draft principles on fair trials and remedies. One provision sought to greatly narrow the scope of when civilians could be tried by military courts (‘Military courts do not have legal authority over civilians except in narrowly defined circumstances, for example, when the civilian has committed an offence in a military facility’: UN Economic and Social Council, Commission on Human Rights, Draft Body of Principles on the Right to a Fair Trial and Remedy (3 June 1994), UN Doc E/CN.4/Sub.2/1994/24, Annex II, para 44).

⁴⁴ eg, Principle 38 of the 1997 version of the United Nations Principles to Combat Impunity includes the following: ‘Because military courts do not have sufficient statutory independence, their jurisdiction must be limited to specifically military infractions committed by members of the military, to the exclusion of human rights violations, which must come within the jurisdiction of the ordinary courts’: Louis Joinet, Question of the Impunity of Perpetrators of Human Rights Violations (Civil and Political) (2 October 1997), UN Doc E/CN.4/Sub.2/1997/20/Rev.1, 38; the 1992 Declaration of the Protection of all Persons from Enforced Disappearance, art 16, states that persons charged with acts of enforced disappearances ‘shall be tried only by the competent ordinary courts in each State, and not by any other special tribunal, in particular military courts’: UN General Assembly, Declaration on the Protection of All Persons from Enforced Disappearance (12 February 1993), UN Doc A/RES/47/133; Principle 5 of the 1985 Singhvi Basic Principles on the independence of the judiciary (adopted by the Commission in 1989) limited military court jurisdiction solely to ‘military offences’: UN Economic and Social Council, Commission on Human Rights, Final Report by the Special Rapporteur, Mr L.M. Singhvi: Draft Universal Declaration on the Independence of Justice (24 August 1987), UN Doc E/CN.4/Sub.2/1985/18/Add.5/Rev; Principle 22(b) of the Johannesburg Principles forbids military courts from trying civilians for ‘security related crimes’: UN Economic and Social Council, Commission on Human Rights, Johannesburg Principles on National Security, Freedom of Expression and Access to Information (2 March 1996), UN Doc E/CN.4/1996/39, Annex; see Andreu-Guzmán (n 20) for more information on these instruments. Similarly, the UN Working Group on Arbitrary Detention commented that the legitimacy of military courts hinges on the observance of four rules: ‘(a) It should be incompetent to try civilians; (b) It should be incompetent to try military personnel if the victims include civilians; (c) It should be incompetent to try civilians and military personnel in the event of rebellion, sedition or any offence that jeopardizes or involves risk of jeopardizing a democratic regime; and (d) It should be prohibited from imposing the death penalty under any circumstances’; see Andreu-Guzmán (n 20) 92, 95.

⁴⁵ OHCHR, ‘Special Procedures’, https://www.ohchr.org/EN/HRBodies/HRC/Pages/SpecialProcedures.aspx; OHCHR, ‘Advisory Committee’, https://www.ohchr.org/EN/HRBodies/HRC/AdvisoryCommittee/Pages/HRCACIndex.aspx.

⁴⁶ The Special Procedures involved in this work have included the Working Group on Arbitrary Detention, the Committee on Enforced Disappearances, and the Special Rapporteur on the independence of judges and lawyers.

⁴⁷ Other international guidelines such as those mentioned in n 46 briefly address the issue of military courts as part of broader issues (eg, judicial independence, enforced disappearances, impunity) but did not do so in a comprehensive way.

⁴⁸ This section covers in considerable detail the process leading to the creation of the Draft Principles and their later promotion. This is not only because of the insight it provides into how the Human Rights Council and subsidiary bodies view military courts but also because it provides an interesting case study of how an issue works its way through the UN human rights system. It also demonstrates how the choice of drafter and his or her personal experiences affect and shape the creation of human rights instruments. As noted by Haldemann and Unger, ‘[w]hile the Principles figure prominently in contemporary human rights discourse, their drafting history is often unknown. This has much to do with the fact that there are no travaux préparatoires documenting multilateral work of the UN in the arena of human rights. The knowledge of who was behind a particular initiative is therefore often lost or transferred within a very small circle of experts. Some information can be found in sources such as decisions, requests, resolutions by the different multilateral human rights entities, but a systematic review of the drafting history is rarely provided. This leaves room for misinterpretation and distortion of the real meaning, ideas, and dynamics behind this initiative’: Frank Haldemann and Thomas Unger, ‘Introduction’ in Haldemann and Unger (n 26) 4, 6. So, too, a summary of the proceedings relating to the Decaux Principles (Section 4.2 below) is useful.

⁴⁹ OHCHR, ‘The Sub-Commission on the Promotion and Protection of Human Rights 2005’, https://www.ohchr.org/Documents/HRBodies/SC/Leaflet2005_En.pdf.

⁵⁰ The Sub-Commission ‘since the 1960s, … has played a pioneering role in drawing the attention of the Commission on Human Rights to the risks of human rights violations arising when the justice is administered by military tribunals’: Louis Joinet, ‘Issue of the Administration of Justice through Military Tribunals’ (9 July 2002), UN Doc E/CN.4/Sub.2/2002/4, para 1 (Joinet Report).

⁵¹ ibid.

⁵² Diane Orentlicher, ‘Prologue’ in Haldemann and Unger (n 26) 1. According to Ní Aoláin, ‘[t]he phrasing of Principle 38 is somewhat more tenuous than its revised form in the Orentlicher 2005 Updated Set of Principles. In the 1997 version, the provision qualifies the exclusion of military courts exclusively because they “do not have sufficient statutory independence”. By 2005, the ouster is definitive and without qualification: “The jurisdiction of military tribunals must be restricted solely to specifically military offences committed by military personnel”’: Ní Aoláin (n 26) 316.

⁵³ Joinet Report (n 50) para 13. Joinet's examples to reflect the ‘growing consensus’ are ‘the positions of the Special Rapporteur on the independence of judges and lawyers, the Working Group on Arbitrary Detention, the Special Rapporteur on extrajudicial, summary or arbitrary executions and the Special Representative of the Commission on Human Rights to monitor the situation of human rights in Equatorial Guinea’: ibid para 37. It should be noted that Joinet's history linking the broadening of military jurisdiction over civilians to ‘colonial wars’, decolonisation and ‘dictatorships in Latin America’ as opposed to ‘conventional wars’ is lacking. However, according to a former Sub-Commission member interviewed by the author, Joinet was particularly affected by his experiences in monitoring military courts in Latin America and this substantially influenced his approach to the issue. Nevertheless, his rhetoric that military jurisdiction has been expanded to target ‘peaceful civil society’ cannot be universally applied, given the very real contexts of civil unrest, terrorism and violent insurgencies that surrounds much use of military courts.

⁵⁴ Joinet Report (n 50) para 5.

⁵⁵ ibid 4, paras 4, 17.

⁵⁶ It could be argued that Joinet relied on the ICCPR (n 28) as it is the primary source of such protection in IHRL. However, IHL instruments from the outset have also embedded concepts of due process. See, eg, arts 12 (death sentences issued by military courts must be reviewed by a higher authority before being carried out), 13 (limits the jurisdiction of military courts), and 148 (prohibition of summary execution of captives) of the Lieber Code: Francis Lieber, ‘General Orders No 100: Instructions for the Government of Armies of the United States in the Field’, 24 April 1863, https://ihl-databases.icrc.org/ihl/INTRO/110.

⁶⁸ Decaux states: ‘In the light of this situation, two solutions are possible, without being incompatible: one can recommend the abolition …’ (Decaux (n 61) para 9). Perhaps as a result of an editing error, he does not provide the second solution in the text, creating confusion as to whether he supports abolition as an ultimate goal. Nevertheless, his recommendations appear to support permanent integration rather than abolition.

⁶⁹ It appears that his more moderate stance was affected by a working paper prepared by Sub-Commission member Françoise Hampson, pursuant to Sub-Commission Decision 2002/104, on the scope of the activities and accountability of armed forces, UN civilian police, international civil servants and experts taking part in peace support operations: UN Economic and Social Council, Commission on Human Rights, Working Paper on the Scope of Activities and Accountability in Peace Support Operations submitted by Françoise Hampson (7 July 2005), UN Doc E/CN.4/Sub.2/2005/42. Hampson notes that members of the armed forces could be held accountable via courts martial conducted by the sending states and recommends that the issue is discussed further in the process spearheaded by Decaux (n 61) paras 10, 32.

Notably, the countries in favour of the resolution have almost all been charged with employing military courts that do not comply with any of these standards and engage in serious abuses: Algeria, Argentina, Botswana, Brazil, Burkina Faso, Chile, China, Congo, Costa Rica, Cuba, Ethiopia, India, Indonesia, Kazakhstan, Kuwait, Mexico, Morocco, Namibia, Pakistan, Peru, Philippines, Russia, Sierra Leone, South Africa, United Arab Emirates, Venezuela and Vietnam. The US voted against, while all other western countries abstained: Austria, Benin, Côte d'Ivoire, Czech Republic, Estonia, France, Gabon, Germany, Ireland, Italy, Japan, Kenya, Macedonia, Maldives, Montenegro, Romania, Saudi Arabia, South Korea, and the United Kingdom.

¹³⁶ The Council called for the ‘participation of representatives of States, the special procedures, including the Special Rapporteur on the independence of judges and lawyers, the chairperson-rapporteurs of the Working Group on Enforced or Involuntary Disappearances, and the Working Group on Arbitrary Detention, the treaty bodies and regional human rights mechanisms, as well as non-governmental organizations and national human rights institutions’: ibid para 12. Surprisingly, the Council did not call explicitly for the participation of military officials or IHL experts.

¹⁶³ Summary of Expert Consultation (n 159) para 77. In March 2018 and November 2019, Yale Law School hosted a group of legal experts to revise the Decaux Principles such that they would gain more international acceptance. That process is still ongoing, though a draft of their proposed revisions can be found at: Global Military Justice Reform, ‘Decaux Principles Workshop’, http://globalmjreform.blogspot.com/2018/04/decaux-principles-workshop.html. As noted by Naluwairo (one of the experts at the Yale conference), the Yale version offers a more nuanced approach than Decaux on the issue of whether military courts may try civilians, and it clearly acknowledges the role of IHL: Naluwairo, Ronald, ‘Improving the Administration of Justice by Military Courts in Africa: An Appraisal of the Jurisprudence of the African Commission on Human and Peoples’ Rights’ (2019) 19 African Human Rights Law Journal 43, 60CrossRefGoogle Scholar.

In its 2006 and 2009 Concluding Observations on the Periodic Report of Uganda, the Commission refers to the Principles, noting that it ‘clearly prohibits the trial of civilians by military tribunals’: AComHPR, ‘Concluding Observations and Recommendations on the Second Periodic Report of the Republic of Uganda’, 40th Session, 15–29 November 2006; AComHPR, ‘Concluding Observations and Recommendations on the Second Periodic Report of the Republic of Uganda’, 45th Session, 13–27 May 2009.

¹⁸³ At the same time the Commission recognises IHL, it recommends fundamental changes to the framework of IHL such as advocating the capture of combatants; proscribing that the use of weaponry that does not strengthen the right to life; and that new technologies should conform to ‘international law’ but not specifically to IHL; see AComHPR, General Comment No 3 on the African Charter on Human And Peoples’ Rights: The Right To Life (Article 4), 57th Session, 4–18 November 2015 (General Comment No 3): ‘F.

The in-depth Commission study and its characterisation as the authoritative view of the Commission going forward appears to mark an important milestone in the regional human rights systems.

²⁵⁰ For example, in the Las Palmeras case, the Inter-American Court of Human Rights noted that under the American Convention on Human Rights, it only has ‘competence to determine whether the acts or norms of the State are compatible with the Convention itself, and not with the 1949 Geneva Conventions’: Case of Las Palmeras v Colombia, Inter-AmCtHR, Judgment of 4 February 2000, (Ser C) No 67, [28]–[33].

²⁵¹ This perception is misguided because IHL contains almost identical due process protections as IHRL and, unlike many aspects of human rights law, cannot be derogated from during armed conflict.

²⁵² See, eg, critiques on the rise of ‘effects-based’ analysis of targeting as opposed to the intent-based framework established under IHL: Corn, Geoffrey S, ‘Targeting, Distinction, and the Long War: Guarding Against Conflation of Cause and Responsibility’ (2016) 46 Israel Yearbook of Human Rights 135Google Scholar.

²⁵³ One notable example where this is taking place is in a European Union-sponsored project in the DRC to create ‘prosecution support units’. The goal of these units is to help civil and military authorities in bringing ‘perpetrators of serious offences, such as war crimes, crimes against humanity, homicide and sexual violence, to justice’. The programme has improved rule of law and respect for human rights. According to the programme manager, ‘one of the benefits has been the link between the military and civil justice systems’. He explains that this work has fostered a ‘culture of cooperation’ rather than ‘competition’: ‘Military justice was more developed in the Democratic Republic of the Congo in the past, but we have reinforced the strength of civil justice’: European Commission, ‘Service for Foreign Policy Instruments’, https://ec.europa.eu/fpi/showcases/restoring-faith-justice-democratic-republic-congo_en.
