States must investigate possible violations of international humanitarian law in armed conflict, and many States use military procedures for all or part of the investigation process. Particular tensions can arise with regard to the perception of justice in the context of military judicial procedures, especially surrounding questions of independence and impartiality. This article lays out the international legal framework which should be used to solve these challenges, arguing that a State must address both the specificities of military institutions and the need for a perception of justice by the affected communities in considering the proper administration of justice in armed conflict.

28 It is suggested that the standards of independence and impartiality in such cases also need to respond to the effectiveness of the investigation as a whole. In some cases, this may mean that it is perfectly acceptable for the commander of a unit implicated in an incident to investigate.

31 The effects of in-group loyalty on cover-up attempts are not unique to armed forces, and have been observed, for example, within private companies (Kundro, Timothy G. and Nurmohamed, Samir, “Understanding When and Why Coverups Are Punished Less Severely”, Academy of Management Journal, Vol. 64, No. 2, 2021CrossRefGoogle Scholar). The phenomenon is, however, particularly problematic in contexts involving potential use of State-sanctioned lethal force such as police and military personnel (Ouellet, Marie, Hashimi, Sadaf, Gravel, Jason and Papachristos, Andrew V., “Network Exposure and Excessive Use of Force: Investigating the Social Transmission of Police Misconduct”, Criminology & Public Policy, Vol. 18, No. 3, 2019, p. 679CrossRefGoogle Scholar).

55 This is evident through the subsidiary and complementary nature of most international mechanisms, such as regional human rights courts and the ICC. It is also observable through mechanisms set up by different UN bodies, often in response to “gross and systematic” violations at the domestic level.
