The principle of distinction

The IHL principle of distinction requires that the parties to the conflict must at all times distinguish between civilians and combatants. Attacks may only be directed against combatants, and correspondingly, attacks must not be directed against civilians, unless and for such time as they directly participate in hostilities.Footnote ¹⁵ Even for civilians without disabilities, fleeing from an area where hostilities are taking place can be fraught with risk of being subject to attacks while moving. This risk is especially great in dynamic and fluid situations like large-scale population movements.

Persons with disabilities – for instance, those with psychosocial or sensory disabilities – may be at even greater risk where their behaviour is misjudged by combatants as directly participating in hostilities or somehow indicating membership in a non-State armed group, which could in turn lead to direct attacks against them.Footnote ¹⁶ Against that background, ICRC recommendations to military commanders specifically made for urban warfare are particularly relevant, including that training scenarios and doctrine not only reflect the operational setting and likely conduct of an enemy, but also include realistic civilian presence (by age, gender, disability and number) and activity, the risks civilians face, and their actions and reactions, so as to familiarize and condition troops prior to deployment.Footnote ¹⁷ Furthermore, all those involved in targeting procedures (both pre-planned and dynamic) should receive comprehensive training and take part in related exercises which include a range of different aspects that help ensure targeting is lawful.Footnote ¹⁸ One aspect of such training should be the positive identification of targets to verify with reasonable certainty that, for instance, a person to be attacked constitutes a lawful target in accordance with IHL; such identification is derived through observation and analysis of target characteristics.Footnote ¹⁹ Training scenarios and doctrine should reflect the reality that persons with sensory, psychosocial or intellectual disabilities may not be able to understand or react to hostilities occurring around them. This specific awareness of potential behaviour by persons with sensory, psychosocial and intellectual disabilities should also feed into the analysis of target characteristics and therefore help to avoid any mistaken presumptions that these people, because of their behaviour, would be targets. To create such specific awareness, the involvement in such trainings of persons with disabilities and organizations of persons with disabilities (OPDs) should be explored.

The principle of proportionality

IHL prohibits attacks that may be expected to cause incidental loss of civilian life, injury to civilians, damage to civilian objects, or a combination thereof that would be excessive in relation to the concrete and direct military advantage anticipated.Footnote ²⁰ It requires military commanders to make that assessment at the planning stage before deciding upon an attack, and to cancel or suspend an attack if it becomes apparent during the attack that it would cause excessive incidental civilian harm.Footnote ²¹ Key to that proportionality evaluation is the determination of what incidental harm to civilians is foreseeable based on all information from all sources reasonably available to the commander in the circumstances, including military but also civilian sources.Footnote ²²

Particularly in urban and other populated areas, due to the intermingling of military objectives with civilians and civilian objects, it is critical that the information collected in the planning process does not only focus on target verification, including to rule out mistaken determinations that civilians with disabilities would constitute lawful targets; it should also serve to assess the incidental civilian harm expected to result from the attack.Footnote ²³ In this assessment, the fact that in many contexts barriers prevent civilians with disabilities from fleeing or being evacuated from areas where hostilities are taking place must be taken into account. Practices such as the assessment of realistic civilian presence, as well as assuming civilian presence in every civilian building unless proved otherwise, would help to take these disability-specific risks of incidental harm into account.Footnote ²⁴

Incidental civilian harm would not only include incidental loss of civilian life, injury to civilians or destruction to civilian objects but also indirect or reverberating effects, often also known as “second- and third-order”, “knock-on” or “long-term” effects. In the ICRC's view, such effects must also be taken into account in the proportionality assessment and in precautions in attack insofar as they are reasonably foreseeable.Footnote ²⁵ For example, incidental damage to critical civilian infrastructure, such as vital water and electrical facilities and supply networks, will likely entail reverberating effects on other essential services, like health-care services, water distribution, power supply and sanitation, which depend on such infrastructure.Footnote ²⁶ This in turn may lead to further deaths or disease among civilians. This is especially relevant in urban warfare, where military objectives are intermingled with civilian objects and where critical civilian infrastructure and essential service systems are largely interconnected and interdependent.

What is reasonably foreseeable varies depending on the circumstances of the attack, but patterns of incidental civilian harm can be foreseen based on past experience.Footnote ²⁷ Foreseeability will be informed and will evolve in particular through analysis of the effects of past attacks, including through the collection of sex-, age- and disability-disaggregated civilian casualty data; studies on the effects of conflicts; better modelling of weapons’ effects; better understanding of the infrastructural set-up and interdependency between services; and new technologies to better assess the presence of civilians and the condition or status of infrastructure and service delivery during the conflict.Footnote ²⁸

In this regard, what has been emphasized by the ICRC for specific gendered impacts of attacks is equally true for disability-specific impacts of attacks; while there is some general understanding of the barriers and risks faced by civilians with disabilities, there is a lack of data on the specific impacts of attacks on such civilians.Footnote ²⁹ For States party to the CRPD, this more granular analysis of barriers and risks faced by persons with disabilities resulting from specific attacks entails an obligation to collect disaggregated data to guide that analysis.Footnote ³⁰ By that token, the foreseeability of disability-specific harm could be improved by military decision-makers.

For civilians with disabilities, there could be specific articulations of such reverberating effects of attacks – for instance, where hospitals or rehabilitation centres, which may more often be needed by certain civilians with disabilities than by others, become fully or partly dysfunctional, or where damage to electricity networks affects the operation of assistive or medical devices, such as wheelchairs, scooters, communication devices, dialysis machines, ventilators or oxygen concentrators, which may be vital for the daily functioning of some civilians with disabilities.Footnote ³¹

A disability-inclusive analysis of specific attacks may also inform the value assigned to particular civilian uses when confronted with the general challenge of contemporary warfare that many objects are used simultaneously for military and civilian purposes in the assessment of incidental harm.Footnote ³² For instance, if certain objects, such as bridges, were to be attacked because by their purpose or use they have become military objectives, and the remaining evacuation options for civilians will result in alternative routes over difficult terrain with numerous physical obstacles, this would mean that some civilians, especially those with physical disabilities, will be more likely not to be able to use these routes, and as a consequence, they may have a higher likelihood of being left behind in an area where hostilities are ongoing, with greater risk of being incidentally harmed.Footnote ³³ If this specific foreseeable harm is omitted from the proportionality assessment, or is not accorded enough priority in that calculus, the fact that the death or injury which may foreseeably result from taking the more difficult route or from staying in the area of hostilities because the evacuation route is not accessible to certain individuals will likely not be considered in the assessment of incidental harm.

While omitting specific foreseeable disability-specific incidental harm confirms the general problem of lack of awareness of disability-specific impacts of the conduct of hostilities, not according priority to such harm where there might be awareness highlights in this specific context the general challenge of inherent value judgements in the application of the principle of proportionality.Footnote ³⁴

The principle of precaution

In addition to the principles of distinction and proportionality, IHL also imposes the obligation on attackers to take constant care to spare the civilian population in all military operations. Parties must take “all feasible precautions” in attack in order to avoid or at least minimize incidental civilian harm (active precautions), and must protect civilians under their control from the effects of attacks (passive precautions).Footnote ³⁵ “Feasible” entails what is possible in practice, taking into account all of the humanitarian and military considerations that prevail at the time; this may be dynamic and may evolve with time, including as a result of past practice and lessons learned.Footnote ³⁶

It is submitted that with this dynamic understanding of evolving information on barriers and risks faced by persons with disabilities, information provided by persons with disabilities themselves, by OPDs and/or by impartial humanitarian organizations should also feed into the considerations on which precautions are based.

The general obligation to take constant care supplements the basic rule of distinction. It applies to the entire range of military operations and not only for attacks within the meaning of IHL. The term “military operations” encompasses “any movements, manoeuvres and other activities whatsoever carried out by the armed forces with a view to combat” or “related to hostilities”.Footnote ³⁷

The obligation of constant care is an obligation of conduct, to mitigate risk and prevent harm. It applies constantly in the planning or execution of any military operation. As a general rule, the higher the risk for the civilian population in any given military operation, the more will be required in terms of care. The requirement to take constant care extends to every aspect of military operational training, planning and mission execution, and is interpreted by some as demanding that soldiers be trained and directed to instinctively endeavour to mitigate civilian risk in all situations.Footnote ³⁸

For instance, in troop movements with a view to attacking military objectives in a town or village, there is a high risk that persons with sensory disabilities will be unable to hear the presence of armed forces. In this regard, in certain contexts, deaf persons have been shot from behind and killed because they did not realize that military personnel were advancing and they were wrongly associated with an adversary in an armed conflict.Footnote ³⁹ What has been observed above regarding positive identification of targets with reasonable certainty is mutatis mutandis relevant here – namely, that specific awareness by parties to armed conflict in such situations may contribute to correctly appraising the behaviour of, and thereby avoiding or mitigating harm to, certain civilians with disabilities. In this context, parties to armed conflict should be alert to attempts by persons with sensory disabilities to communicate to them that a person is not a lawful target. For instance, a deaf person might wave their hand, or a piece of cloth, tree branch or handkerchief, to combatants to express this.Footnote ⁴⁰

Active precautions include those that can be taken in the choice of means and methods of attack with a view to avoiding, or in any event minimizing, incidental civilian harm.Footnote ⁴¹ Generally, this includes consideration of the timing of attacks in order to choose a moment for attacking military objectives when there are fewer civilians present, such as at night rather than in the middle of the day.Footnote ⁴² Given that civilians with disabilities face specific difficulties with regard to leaving the vicinity of military objectives for safer spaces, considerations of the timing of attacks are especially relevant; it appears that parties to armed conflict have delayed military operations because the military objective was surrounded by civilians, including civilians with disabilities.Footnote ⁴³

Another active precaution that is particularly relevant for civilians with disabilities is that parties to armed conflicts must give effective advance warnings of attacks that may affect the civilian population, unless the circumstances do not permit.Footnote ⁴⁴ The effectiveness of a warning should be assessed from the perspective of the civilian population that may be affected. It should reach and be understood by as many civilians as possible who may be affected by the attack, and it should give them time to leave, find shelter or take other measures to protect themselves.Footnote ⁴⁵ The general planning considerations for commanders for implementing effective advance warnings include varied formats of communication, ensuring that the content of messages is clear and easy to understand, what constitutes sufficient notice for the civilian population to react to the warning, and whether the population is free to react to the warning.Footnote ⁴⁶

These considerations should be appropriately contextualized in order to render them inclusive for persons with disabilities as part of the civilian population. For instance, issuing such warnings in a disability-inclusive manner requires presenting accessible information in a variety of formats that takes into account the diversity of impairments of persons with disabilities. Radio messages alone will not be heard by persons with hearing impairments, who would need the information to be presented to them in sign language. Leaflets or other exclusively visual forms of warning will not be seen by persons with visual impairments. Complex instructions and warnings, if not simplified, will not be understood by persons with intellectual impairments.Footnote ⁴⁷ Exploring options to equip parties to armed conflict with certain language competences, such as the local sign language, by relying either on already existing skills within a party to a conflict or on external experts (including civil authorities and OPDs), would help in the diversification of formats of communication and would increase the range of means of communication in a more disability-inclusive manner.Footnote ⁴⁸

Civilians with disabilities may need more time to leave an area of impending military operations, and this aspect should also be taken into account in informing the decision by attackers as to when a warning should be issued and how much time will be granted to the civilian population until the warning expires.

In terms of passive precautions for defenders, these may include the construction of safe shelters, the withdrawal of the civilian population to safer places, or temporary evacuations to allow civilians to leave for safer areas by their own free will while military operations are ongoing.Footnote ⁴⁹ Forcible evacuations, on the other hand, are prohibited as forcible transfers, deportations or displacement, unless they are undertaken for the security of civilians themselves, including that of civilians with disabilities, or are dictated by imperative military necessity.Footnote ⁵⁰ To ensure that evacuations are not forced or unlawful, they must remain limited to the time required by the circumstances. When those circumstances cease to exist, displaced persons, including displaced persons with disabilities, have a right to voluntary return in safety to their homes or places of habitual residence.Footnote ⁵¹

Taking passive precautions in a disability-inclusive manner means, for instance, ensuring that safe shelters are physically accessible to wheelchair users or that information on their location is accessible for those with intellectual disabilities. It means giving specific consideration during evacuations to identifying persons with disabilities, ensuring accessible means of transport, allowing for their personal assistants and caretakers to accompany them, and ensuring that they are able to keep assistive devices with them or have access to suitable alternatives in case those devices have been lost or damaged.Footnote ⁵²

Finally, it must be emphasized that even if civilians are not able to act on an effective advance warning, cannot access safe shelter and cannot be part of temporary evacuations, they continue to benefit from all general protections afforded to civilians, including the principles of distinction, proportionality and precaution.Footnote ⁵³ This is absolutely crucial for civilians with disabilities in light of their specific barriers to accessing warnings, shelter or evacuation operations, and/or their lack of willingness to leave their habitual homes, especially older civilians with disabilities. As a result of these factors, many will continue to be present in danger zones.

Specific protection of persons with disabilities

A disability-inclusive interpretation and implementation of IHL is also reinforced by specific protections for persons with disabilities as part of civilian populations. These specific protections do not exist in isolation from the general protections for civilians; rather, they are a recognition of the specific risks, including from military operations, faced by certain groups within the civilian population like persons with disabilities, but also older persons, women and children.

The terminology used in provisions of the Geneva Conventions (including Geneva Convention IV (GC IV)) to describe persons with disabilities, like “infirm”,Footnote ⁵⁴ and the notion that persons with disabilities deserved specific protection because they were thought to be in a state of weakness due to their physical or mental condition, were a product of the social and historical context at the time.Footnote ⁵⁵ It is well understood today that these terms and concepts, which narrowly focus on the individual condition of the person with disability through a medical perspective and arguably view them as weak and passive victims in need of protection, are certainly outdated in light of contemporary understandings of disability.Footnote ⁵⁶ Although we can and must move beyond such terms and notions, we must not discard the important recognition already present in the minds of the drafters of the Geneva Conventions that certain groups of civilians, including civilians with disabilities, require specific consideration.Footnote ⁵⁷

The gist of specific protections under IHL is encapsulated by the obligation that persons with disabilities are entitled to special respect and protection. This obligation, which is enshrined in treaty law applicable to international armed conflicts (IACs) in GC IV and in customary IHL for all types of armed conflict,Footnote ⁵⁸ requires that parties to armed conflict refrain from attacking, otherwise harming or ill-treating persons with disabilities, and that those parties take active measures to assist and protect such persons from harm. The obligation to “assist and protect” is to be broadly interpreted to cover protection or support from a wide range of harms or dangers. The harms or dangers from which persons with disabilities are to be protected include those arising from hostilities; from violence, exploitation or ill-treatment, both by combatants and by civilians; and from the risk of exacerbation of an existing impairment or secondary impairment if existing medical services or support become inaccessible.Footnote ⁵⁹

Therefore, specific protection is applicable to the conduct of hostilities but also when the person concerned is under the control of a party to a conflict.Footnote ⁶⁰ Further rules address certain aspects of the implementation of this obligation, such as the obligation under GC IV to facilitate steps taken to assist civilians (other than wounded or shipwrecked civilians) in grave danger.Footnote ⁶¹ The kind of measures to be facilitated would be similar to the feasible precautions taken to protect civilians under the control of parties to armed conflict from the dangers of military operations and may concern, for instance, evacuating persons with disabilities or providing accessible temporary safe shelters.Footnote ⁶²

From a contemporary perspective, the main challenge is to consider the diversity of impairments of persons with disabilities and the variety of barriers faced by different persons with disabilities, and tailoring measures to address these barriers in the interpretation and implementation of specific protections.

The complementarity between IHL and the obligations of States party to the CRPD assists in this regard. Article 11 of the CRPD is an explicit expression of this complementarity, as it obligates States Parties to take all necessary measures to ensure the protection and safety of persons with disabilities in situations of armed conflict, in accordance with their obligations under international law, including IHL and IHRL. A contemporary interpretation of IHL can be based on the social and human rights model of disability and the evolving concept of disability underlying the CRPD, and includes among persons with disabilities those with physical, psychosocial, intellectual or sensory impairments that – in interaction with various barriers, be they physical, communication, attitudinal or institutional – result in specific risks from military operations and prevent such persons from accessing protections under IHL.

Reading the IHL obligation of “special” respect and protection of persons with disabilities in light of the complementarity with the CRPD presupposes that not only persons with physical disabilities are identified as such but also those with less visible disabilities, including persons with sensory, intellectual or psychosocial disabilities. Identifying the location and diversity of persons with disabilities raises the issue of implementation of the obligation to collect publicly available disability-disaggregated data of sufficient quality under the CRPD as a basis for inclusive interpretation and implementation of specific protections under IHL.Footnote ⁶³ The involvement of civilian actors, including civil authorities, OPDs and impartial humanitarian organizations, may enable parties to armed conflicts to obtain more precise information on persons with disabilities when conducting their military operations and may help to temporarily remedy gaps or errors on data available in a given State. Still, coordination and centralization of the data from various sources will be necessary to ensure that the information is accurate and reliable.Footnote ⁶⁴

The complementarity between IHL and the CRPD also means that the nature and variety of the barriers faced by diverse persons with disabilities must be effectively addressed by measures other than the provision of medical services. It is important to affirm a broader approach of IHL to persons with disabilities, since IHL has been repeatedly criticized as taking an outdated, medicalized approach to such persons, focusing merely on the person's individual condition (i.e. the impairment) that requires medical treatment.Footnote ⁶⁵ In particular, as already mentioned, a person with a hearing impairment or a visual impairment will face specific communication barriers, which, if unaddressed, will lead to specific risks of that person not accessing information permitting their protection during hostilities. To address such communication barriers, it is not medical care or a medical competence which is primarily needed, but rather competence in sign language or Braille. To avoid or minimize the risk of wrongful attacks or violence against persons with psychosocial or intellectual disabilities due to misjudging their behaviour, whether in hostilities or in situations where persons with psychosocial or intellectual disabilities come under the control of combatants, it is not mental health services that would address this challenge. Rather, in attacks or troop movements, and in screening operations at military checkpoints or during house-to-house searches, more specific awareness by weapons bearers of potential reactions to their presence by persons with psychosocial or intellectual disabilities should be raised through training, and some basic guidance on appropriate military behaviour when encountering persons with psychosocial or intellectual disabilities should be provided.

The variety of lived experiences of persons with disabilities may also be captured when IHL-specific protections are complemented by the CRPD. For instance, negotiators of the 1949 Geneva Conventions had in mind the scenario of civilians trapped in air raid shelters as a particular example of persons in grave danger requiring the facilitation of specific measures to assist them.Footnote ⁶⁶ However, the wording of “other persons exposed to grave danger” and the intention of the drafters make it clear that this is to be viewed as a catch-all category aimed at ensuring that the groups of civilians explicitly mentioned would not be understood as a restrictive list.Footnote ⁶⁷ The complementarity with the CRPD, which expressly recognizes the diversity of persons with disabilities in light of their lived experiences, reinforces an interpretation of this provision that covers persons with disabilities or older persons who may not be trapped in shelters but in their homes and who are therefore at grave risk because they cannot or do not intend to flee military operations.Footnote ⁶⁸

In order for parties to armed conflict to effectively facilitate steps taken to assist civilians with disabilities in grave danger from military operations, operational cooperation and coordination between parties to armed conflict, civil authorities and other actors like OPDs and impartial humanitarian organizations are crucial. Such cooperation and coordination may also render the implementation of feasible precautions for the general protection of civilians more effective, such as evacuations. This reflects the reality that often measures like evacuations will actually be performed by actors other than parties to the armed conflict, and these actors will thereby support parties to armed conflicts in implementing their IHL obligations.Footnote ⁶⁹

Mechanisms of coordination and cooperation should be put in place in advance before an armed conflict occurs due to the fact that during an armed conflict, the obligation to facilitate steps taken by other actors than a party to a conflict itself are subject to the caveat “as far as military considerations allow”. What is feasible in terms of precautions also hinges upon military considerations besides humanitarian concerns.Footnote ⁷⁰ Military considerations like ongoing hostilities or the necessity of establishing military positions without revealing them to civilian actors, including those with enemy nationality, may temporarily prevent allowing such stakeholders to access certain areas.Footnote ⁷¹

A specific way to implement precautions both in attack and against the effects of attack in besieged and encircled areas, as well as the specific protections applicable to groups of civilians provided by GC IV, is to draft local agreements between belligerents in order to allow those groups of civilians, including persons with disabilities, to be evacuated.Footnote ⁷² Such agreements should cover, generally, details like the number of people to be evacuated, the beginning and duration of any truce to enable the evacuation to proceed, the means of transport, and the route to be taken.Footnote ⁷³ In order for persons with disabilities to be part of such evacuations, the specific considerations already elaborated above in relation to feasible precautions should also be included.

Humane treatment

In all of the aforementioned situations of being in the power of a party to a conflict, persons with disabilities benefit from certain fundamental guarantees; above all, they must be treated humanely, without any adverse distinction.Footnote ⁷⁴ This obligation is based on respect for a person's physical and mental integrity and their inherent dignity. However, the meaning of humane treatment is not defined under IHL. This omission is deliberate, as the definition is context-specific. Today, the ICRC understands this obligation to require parties to armed conflict to consider an individual's identity, including their age, sex, impairment, and social, cultural, religious or political background. Their past experiences and how these experiences, along with the person's risks or needs, are shaped by environmental factors, notably the socio-cultural, economic and political structures in place, must also be taken into account.Footnote ⁷⁵ Therefore, the meaning of what constitutes humane treatment is inherently dynamic and subject to changes in society.Footnote ⁷⁶

Specific acts of ill-treatment

While humane treatment carries an independent meaning, IHL also prohibits specific acts of ill-treatment, such as torture and other cruel, inhumane or degrading treatment or punishment. For evaluating whether specific conduct amounts to prohibited ill-treatment, the specific individual circumstances of the person ill-treated must be taken into account, including their physical or mental condition, their gender, age, social, cultural or religious background, and their past experiences, as well as environmental factors such as prevailing social and cultural conditions.Footnote ⁷⁷

The prohibition against adverse distinction, de facto equality and complementarity with CRPD obligations related to accessibility and reasonable accommodation

The obligation of humane treatment must also be considered together with the prohibition against adverse distinction. “Disability” is not explicitly mentioned as a prohibited ground of adverse distinction under IHL, but it is nevertheless encompassed by the prohibition, as adverse distinction based on “any other similar criteria” as those explicitly listed is equally prohibited.Footnote ⁷⁸ Therefore, the IHL prohibition against adverse distinction can be interpreted as converging with the prohibition against discrimination on the basis of disability which is explicit in the CRPD.Footnote ⁷⁹

Since only “adverse” distinction is prohibited, measures of differentiation or prioritization which take into account the specific risks faced by persons with disabilities may not only be allowed but may even be required. Thus, non-adverse distinctions may actually be necessary to ensure humane treatment in the different situations in which persons with disabilities may find themselves.Footnote ⁸⁰

This may require the taking of all feasible measures to remove and prevent the raising of any barriers that persons with disabilities might face in gaining equal access to services or protections provided under IHL compared with other civilians or persons hors de combat. When interpreted to include these positive obligations, IHL converges with obligations to advance the de facto or substantive equality of persons with disabilities under human rights law, in particular the CRPD.Footnote ⁸¹

Central to ensuring substantive equality between persons with disabilities and other persons are obligations under the CRPD to ensure accessibility of the physical environment, information, communications and services, as well as the provision of reasonable accommodations in individual cases when needed.Footnote ⁸² With regard to taking positive appropriate measures related to accessibility, the CRPD explicitly includes the identification and elimination of barriers to accessibility, be they physical, communicative, attitudinal or institutional.Footnote ⁸³

Screening operations

The inherently dynamic interpretations of humane treatment and the prohibition of adverse distinction under IHL, in harmony with the CRPD, allow for disability-specific contextualizations in a range of situations in which persons with disabilities are in the power of a party to a conflict.Footnote ⁸⁴ For instance, these considerations allow us to appreciate the importance of assistive devices for respecting the dignity of persons with disabilities whose movement is restricted, such as when they are at checkpoints or detained. If assistive devices that have supported a person's functioning for a long time are damaged, or are confiscated and not returned, the harm to a person's dignity becomes clear when it is understood that, for persons with disabilities, assistive devices are not simply objects but are extensions of their bodies.Footnote ⁸⁵ In a similar vein, refusing to allow a person with a disability to be accompanied through checkpoint controls by their support person, personal assistant or caretaker could also encroach on that person's dignity.Footnote ⁸⁶

In screening operations where parties to armed conflict aim to control large population movements, a disability-inclusive implementation of the obligation to treat civilians and persons hors de combat humanely and without adverse distinction would emphasize appropriate measures to ensure accessibility to information on the process of such operations.Footnote ⁸⁷ These measures would go some way to reducing the potential for violent encounters and inappropriate behaviour, including cruel, inhuman or degrading treatment by parties to armed conflicts and their representatives towards persons with disabilities.Footnote ⁸⁸

Detention conditions

In situations of conflict-related detention, specific conduct and detention conditions which have already been held by the International Criminal Tribunal for the former Yugoslavia (ICTY) to constitute torture or cruel, inhuman or degrading treatment would be specifically relevant for detainees with disabilities. Such conditions include lack of adequate medical attention;Footnote ⁸⁹ more broadly inhumane living conditions in places of detention with regard to adequate food, water, clothing, medical care, shelter or contacts with the outside world;Footnote ⁹⁰ and solitary confinement, in view of its strictness, its duration and the objective pursued.Footnote ⁹¹

The ICTY drew on the case of a detainee with a psychosocial impairment among a group of several others with mental health conditions in determining detention conditions that amount to cruel treatment in violation of Article 3 common to the four Geneva Conventions. It invoked the very restrictive detention environment of the detainee, who had no possibility of taking outdoor walks to relieve his psychological stress, leading him to adopt self-harming behaviour such as cutting off his ear and fingernails. The effects of that environment were exacerbated by the severe lack of food, which provoked extreme hunger, causing the detainee to eat insects when he caught them. Finally, the guards were aware of the existence of a group of detainees with psychosocial impairments but did not take any positive action to accommodate those detainees.Footnote ⁹² The ICTY relied on these facts to establish the severity of physical and mental consequences suffered by this person with a psychosocial disability necessary for concluding that cruel treatment had been committed.Footnote ⁹³

Severe beatings and the refusal to urgently transfer a detainee with a hearing impairment to an external hospital outside of a detention camp, whereupon this detainee died, were at the core of another finding of cruel treatment by the ICTY in the context of a non-international armed conflict (NIAC).Footnote ⁹⁴ However, what received less attention by the judges was the testimony by a witness who believed that the guards beat this detainee even more than other detainees without disabilities. This was allegedly because the guards thought that the detainee was refusing to answer their questions, but in fact his lack of response was due to his hearing impairment and inability to speak, of which they were unaware.Footnote ⁹⁵ This demonstrates the risk of ill-treatment as a reaction to persons with psychosocial or sensory disabilities when there is a lack of awareness on the part of Detaining Powers faced with such persons within their detainee population.

In another case, severe and repeated beatings which caused a detainee with physical and psychosocial disabilities to lose consciousness numerous times formed the main basis for a determination of cruel treatment, in the same way as repeated beatings constituted cruel treatment for detainees without disabilities. In addition, however, the ICTY also found that the detainee with disabilities was subjected to beatings which specifically targeted his impaired limbs.Footnote ⁹⁶ Witness testimonies further specified that this detainee had wandered off from the place of detention when going to the toilet, unaware of his surroundings and probably believing he was going home, and that the guards found him, brought him back and thereafter targeted his limbs specifically.Footnote ⁹⁷

These cases illustrate that general conditions of detention, to which persons without disabilities are also exposed, can have a specific impact on detainees with disabilities. That impact needs to be taken into account when evaluating humane treatment; the specific consequences may include an exacerbation of the impairments of detainees with disabilities. This also underscores the importance of positive measures of accessibility and, where necessary in individual cases, of specific targeted measures of reasonable accommodation, in order to ensure that detainees with disabilities have humane detention conditions, without adverse distinction, and are not exposed to ill-treatment.

In its most recent Commentary on Geneva Convention III (GC III), the ICRC emphasized that support services in camps must be available to all prisoners of war (PoWs), including those with disabilities, and that to ensure equal treatment, the specific needs and risks of individual prisoners must be identified, assessed and provided for. This in turn requires appropriate planning and preparatory measures.Footnote ⁹⁸

Aspects related to accessibility and reasonable accommodations are also highlighted in the ICRC's interpretations of specific provisions of GC III. For instance, in relation to the obligations related to toilet facilities for the use of all PoWs, day and night, the ICRC stressed that in combination with the requirement of equal treatment under GC III, “accessibility also implies that all prisoners of war, without any adverse distinction, for example based on other factors such as age or disability, have constant and easy access to toilet facilities”.Footnote ⁹⁹ It then shared as an example observed from its own detention visits the fact that some Detaining Powers had made structural adjustments to sanitary facilities in order to accommodate certain PoWs with disabilities, for instance by equipping those facilities with extra stools.Footnote ¹⁰⁰

Other feasible measures in relation to physical infrastructure may include the construction of ramps, handrails or wider corridors and doorways.Footnote ¹⁰¹ In relation to medical care and rehabilitation of PoWs, the ICRC emphasized measures of information accessibility for PoWs with visual impairments in order to include diverse communication methods, ranging from Braille to audio and large print.Footnote ¹⁰² Finally, formulations like taking all necessary measures to ensure “adequate premises” and the “necessary equipment” lend themselves to a harmonized reading with obligations related to accessibility and reasonable accommodation under the CRPD; one example of this are the obligations related to the pursuit of intellectual, educational or recreational activities, which also recognize explicitly the individual agency of prisoners, as the “individual preferences” of prisoners must be respected.Footnote ¹⁰³

Specialized health-care and rehabilitation services are also recognized for PoWs with disabilities in GC III. Article 30(2) of GC III provides that special facilities shall be afforded for the care of prisoners with disabilities, in particular prisoners who are blind, and for their rehabilitation.Footnote ¹⁰⁴ While the explicit mention of prisoners with visual impairments was included as a result of the specific experience during the Second World War, the prohibition against adverse distinction would preclude giving priority to one group of persons with specific types of impairments over others.Footnote ¹⁰⁵ On this basis, the ICRC has monitored whether therapies such as physiotherapy, psychotherapy and psychosocial counselling, if necessary for prisoners with disabilities, have been provided so that these prisoners might attain and maintain their optimal physical and mental functioning in interaction with their environments.Footnote ¹⁰⁶ Geneva Conventions III and IV also contain specific obligations in relation to assistive devices, whereby PoWs and civilian internees must benefit from “any apparatus necessary for their maintenance in good health” free of charge.Footnote ¹⁰⁷ “Maintenance in good health” would include avoiding the risk of an exacerbation of an already existing impairment of a PoW or civilian internee in the absence of the availability of assistive devices.Footnote ¹⁰⁸

Similar issues would also arise in NIAC-related detention – for instance, rendering infrastructure providing “safeguards of health and hygiene” accessible to detainees with disabilities.Footnote ¹⁰⁹ In the context of the provision of food, suggested accessibility measures and reasonable accommodations relevant for certain detainees with disabilities include longer times to eat, support with eating meals, and adapted meals.Footnote ¹¹⁰ Should it be necessary to evacuate detainees in order to remove them from the danger of military operations, similar considerations to those described above in relation to the rules on the conduct of hostilities pertaining to evacuations would also be relevant here.Footnote ¹¹¹ As in the case of detention related to IACs, the importance of the staff of Detaining Powers communicating orders and instructions in an accessible manner has also been highlighted.Footnote ¹¹²

Furthermore, consultations held by the ICRC with States on strengthening legal protections for persons deprived of their liberty, in particular in NIACs, confirmed the need for specific differentiated measures for detainees with disabilities in order to ensure humane conditions of detention for them. While the operational circumstances of NIAC-related detention may be different, these consultations also stressed the importance of advance planning for implementing specific measures in favour of detainees with disabilities, including the preparation and training of forces to identify and engage with such detainees and consideration of the specific skills necessary to identify, anticipate and address their specific needs.Footnote ¹¹³

The need for positive measures for ensuring substantive equality, including through reasonable accommodation regarding detention conditions, is also specifically reflected in Article 14(2) of the CRPD on the right to liberty and security, and the interpretation of this provision provided by the CRPD Committee.Footnote ¹¹⁴ The CRPD Committee and other IHRL bodies and experts have also supported the position that a lack of measures of accessibility and/or reasonable accommodation for persons with disabilities, as well as the exacerbation of their impairments in detention, may amount to prohibited ill-treatment.Footnote ¹¹⁵

Prevention of arbitrary or unlawful deprivation of liberty of persons with disabilities

Apart from the necessity of ensuring humane treatment, including accessible detention conditions and reasonable accommodations in detention, it is also necessary to ensure that persons with disabilities are not arbitrarily or unlawfully deprived of their liberty in armed conflicts in the first place. In this regard, the challenge already observed in relation to armed forces misinterpreting behaviour, especially by civilians with sensory, psychosocial or intellectual disabilities, has also led to detention of such persons by armed forces because of the erroneous association with non-State armed groups or interpretation of their conduct as threatening.Footnote ¹¹⁶

In order to prevent arbitrary or unlawful conflict-related detention, international law requires grounds and procedures established by law. Regarding grounds for conflict-related detention, IHL recognizes that a person may be deprived of their liberty in connection with a criminal process,Footnote ¹¹⁷ because of their status as a PoW (in IACs only), or as a measure of control to mitigate a security threat posed by the person to an opposing party to the conflict.Footnote ¹¹⁸

In IACs, PoWs are presumed to represent per se a security threat to opposing armed forces under GC III, and Article 21 of GC III reflects the agreement of States that internment on the basis of their status is permitted.Footnote ¹¹⁹

In contrast, under GC IV, internment of civilians in IACs represents an exceptional measure where the security of the Detaining Power makes it “absolutely necessary”,Footnote ¹²⁰ or for “imperative reasons of security”.Footnote ¹²¹ While for NIACs IHL mentions that internment may also occur in such situations, it does not specify the grounds or procedures for internment. Although PoW and combatant status do not exist in NIAC, in the context of the ICRC consultations with States on strengthening legal protection for persons deprived of their liberty there was some debate on whether a factual finding of membership in a non-State armed group would constitute in and of itself a sufficient ground for internment, or whether there must be an individualized determination of a specific imperative threat to security posed by that person to the Detaining Power.Footnote ¹²²

In any event, non-compliance with military instructions by persons with sensory, psychosocial or intellectual disabilities or the existence of an impairment would not be sufficient to assume that a ground for internment exists, be that PoW status, membership in a non-State armed group or an imperative threat to the security of the Detaining Power.

Combatant membership in State armed forces giving rise to PoW status, as well as membership in non-State armed groups, must be positively verified under IHL and not just lightly presumed. This is evident in IHL rules relating to the determination of PoW status in situations of doubt by a competent tribunal, which would also include situations where a captured person would claim not to have that status, bearing in mind the general implication of internment until the end of active hostilities.Footnote ¹²³

Further, even if one were to support the view that membership in a non-State armed group is sufficient as a ground for internment, as has been observed in the consultations led by the ICRC with States on strengthening legal protections of persons deprived of their liberty, detention resulting from unverified or mistaken identity may be deemed arbitrary.Footnote ¹²⁴ This would also be relevant in the case of civilians with disabilities whose conduct is wrongly assumed to be indicative of membership in a non-State armed group or direct participation in hostilities.

Generalized assumptions based on an incorrect understanding of conduct of persons with disabilities or on the existence of a disability as justification for internment and the finding that an imperative threat to security exists would also be arbitrary. This is because of the fact that the determination of such a threat is subject to an individualized assessment, without discrimination.Footnote ¹²⁵ In this regard, both State military manuals and international jurisprudence clarify that a person's identity or state of belonging to a certain group of persons, including on the basis of nationality, age or political beliefs, are not, on their own, sufficient grounds justifying internment.Footnote ¹²⁶

It is submitted that the same reasoning should be applied to persons with disabilities, including persons with sensory, psychosocial or intellectual impairments. In this regard, the CRPD absolutely prohibits deprivations of liberty based on the existence of an impairment because such deprivations of liberty have been held to be discriminatory.Footnote ¹²⁷ Generally, assuming that a person with a disability constitutes an imperative threat to security because that person cannot comply with military instructions would disproportionately and adversely affect persons with certain types of impairments compared to persons without disabilities; it would not take into account the inaccessibility of those instructions and would lead to a wrong conclusion. Such an assumption would therefore be discriminatory. The same would be true where a threat is simply presumed on the basis of an impairment, as this would affect persons with certain impairments specifically and adversely compared to persons without disabilities.

This does not mean that persons with disabilities may never be interned in an armed conflict. They could be interned if the determination of their membership in armed forces or their constituting an imperative threat to security (as a ground justifying the internment) is not based on their disability, directly or indirectly, and is made objectively and on an equal basis for each individual.Footnote ¹²⁸

In line with the general recognition that the alleged commission of a crime may provide a ground for deprivation of liberty, it is also not precluded that persons with disabilities may be detained on that basis. When the alleged crime has a sufficient nexus to an armed conflict, the treatment of the detainee is governed by IHL.Footnote ¹²⁹ In any event, procedural safeguards as well as fair trial guarantees constitute a necessary guarantee against arbitrariness of deprivations of liberty and ensure that grounds of internment or the commission of a crime are substantiated in specific cases.

In terms of internment, procedural safeguards include the guarantees found in GC IV and Additional Protocol I (AP I) to prompt access to information about the reasons for internment; the right to have the initial decision to intern reviewed; and the periodic reassessment of the continued necessity to intern.Footnote ¹³⁰ In the ICRC's view, these and other procedural safeguards should also be applied – as a matter of law and policy – in internment occurring in NIACs.Footnote ¹³¹

As regards judicial or fair trial guarantees against the arbitrariness of detention for criminal charges related to an armed conflict, these include the right of the accused to be informed of the reasons for their arrest as well as the nature and cause of the alleged offence;Footnote ¹³² the right to be promptly brought before a judicial authority at the pre-trial stage;Footnote ¹³³ the right to challenge the lawfulness of detention before a court (habeas corpus);Footnote ¹³⁴ the right to be tried before a regularly constituted, independent and impartial court;Footnote ¹³⁵ necessary rights and means of defence;Footnote ¹³⁶ and the right to be advised of one's judicial and other remedies and the time limits within which they may be exercised,Footnote ¹³⁷ given that convictions for a crime will often carry the imposition of deprivation of liberty as a sentence.

Ensuring that detained persons with disabilities have access, without adverse distinction/discrimination, to the same procedural or fair trial guarantees as detainees without disabilities in armed conflicts may allow for and even require specific measures of accessibility or procedural accommodations. One key area in this regard is information accessibility. The initial information provided to a person deprived of their liberty on the reasons for the detention and the nature and cause of the alleged offence must be conveyed in a language that the person understands; thereby, detainees are enabled to challenge the lawfulness of their detention and to exercise any necessary rights and means of defence.Footnote ¹³⁸ For detainees with disabilities, the necessary accessibility and procedural accommodations should be made to ensure their fair trial guarantees.

Specific issue: Norm conflict between IHL allowing for isolation of prisoners of war and civilian internees with psychosocial or intellectual disabilities versus CRPD prohibition of detention based on impairment

Article 30 of GC III and Article 91 of GC IV provide for “isolation wards” which shall be “set aside” for cases of “mental disease”. These provisions are placed under chapters dealing with the hygiene and medical attention devoted to PoWs and civilian internees respectively. These are restrictions to liberty additional to what would be permissible by the fact that the detainees are combatant members of the armed forces (in the case of PoWs) or are deemed to represent an imperative threat to security to the Detaining Power (in the case of civilian internees in IACs under GC IV).Footnote ¹³⁹

While there is no definition of what “isolation wards” precisely entail, in its ordinary meaning in a health context, this term usually refers to a specific room or section of a health-care facility “where people with a contagious disease are kept separate from people who are not infected”.Footnote ¹⁴⁰ As such, this form of further restriction of liberty may be necessary on the basis of containing an overriding risk of infection for other patients (or, in the case of a detention facility, other detainees), and ultimately, an epidemic that could spiral out of control.Footnote ¹⁴¹ This kind of measure may also be based on other obligations of the Detaining Power related to the prevention of epidemics and the safeguarding of health and hygiene in conflict-related detention.Footnote ¹⁴² Thus, the character of this additional deprivation of liberty from internment is based strictly on health grounds (medical isolation) and is therefore distinct from additional deprivations of liberty as a penal or disciplinary punishment, including solitary confinement (i.e., detention in a single cell for very long periods of the day without meaningful human contact)Footnote ¹⁴³ or any other form of confinement, like close confinement.Footnote ¹⁴⁴

However, isolation on the ground of “mental disease” is a completely different case, despite it being regulated in the same provision as isolation for contagious diseases. Neither Article 30 of GC III nor Article 91 of GC IV offer a definition of what isolation because of a mental health condition or psychosocial disability means, or the rationale for such isolation. The drafting history shows that “mental disease” was added very late in the negotiations at the 1949 Diplomatic Conference; it was inserted first in the Draft Third Convention upon the proposal of one delegation and then for consistency purposes also in the Draft Fourth Convention, and subsequently adopted with no further discussion.Footnote ¹⁴⁵

The 1958 Commentary on GC IV Article 91 justified the insertion of “mental disease” as a further ground for isolation; while the Commentary recognized that “segregation may seem somewhat cruel in this case, especially when it is remembered that internment itself may have been the cause of mental affliction (or have aggravated an already disturbed mental condition)”,Footnote ¹⁴⁶ it asserted that the “crowded living conditions” made such isolation “absolutely necessary in the interests of the internees as a whole”.Footnote ¹⁴⁷

From this passage in the Commentary, it is not entirely clear what would make isolation absolutely necessary, nor what segregation would precisely consist of; still, it may be discerned that even in 1958, segregation was already seen as harmful for the person with a psychosocial disability. This did not rule out forms of deprivation of liberty similar or equal to solitary or close confinement imposed as a punishment, however, and in this case the interests of the other internees were perceived as overriding the individually harmful impacts of isolation.

This precedence accorded to the interests of other detainees over the individual impact on the detainee with a psychosocial disability suggests that isolation would be based on the presumption that the detainee is perceived to represent a danger to the rest of the camp population. This general presumption has been proven wrong, however, with evidence showing that persons with psychosocial disabilities are more likely to be victims of violence than perpetrators of it.Footnote ¹⁴⁸

Still, this general assumption of dangerousness associated with persons with psychosocial disabilities as a whole is deeply entrenched and constitutes a key attitudinal barrier. When analyzed against the stringent wording of Article 14(1)(b) of the CRPD for States party to the Convention, the absolute prohibition on deprivation of liberty based on an impairment would even be violated if the element of perceived dangerousness were to be invoked as an allegedly objective ground while in fact, it would primarily affect persons with psychosocial (or intellectual) impairments. In light of this, it would constitute prohibited discrimination based on impairment under Article 5 of the CRPD, whatever the form of the additional restriction of deprivation of liberty.Footnote ¹⁴⁹ Despite this interpretation, some States explicitly reserve the possibility, for instance, of imposing isolation on PoWs or civilian internees with mental health conditions or psychosocial disabilities where this is deemed unavoidable in light of the danger that those persons pose to themselves or to others.Footnote ¹⁵⁰

Thus, prima facie, a norm conflict exists, especially for States party to the CRPD, between Article 30 of GC III and Article 91 of GC IV, on the one hand, allowing for isolation based on mental health conditions or psychosocial disabilities, as retained by some State practice, and Article 14(1)(b) of the CRPD, on the other, absolutely prohibiting any detention based on impairment. However, the IHL provisions must also be interpreted in their context, including fundamental obligations which constitute a reference for understanding these specific provisions, other obligations of the Detaining Power contained in the same provision, and other relevant obligations governing release, repatriation, return to place of residence or accommodation in a neutral country.

As regards fundamental IHL obligations which guide the interpretation of specific provisions, these include the prohibition on adverse distinction, as well as the obligations of humane treatment and related prohibitions on torture and other ill-treatment.Footnote ¹⁵¹ Firstly, the aforementioned convergence between the IHL prohibition and the explicit prohibition of non-discrimination based on impairment under the CRPD, due to the open-ended list of grounds of adverse distinction under IHL, makes a dynamic interpretation of the prohibition on adverse distinction as encompassing disability-specific deprivations of liberty in armed conflict possible.Footnote ¹⁵² Secondly, in this context, invoking obligations of humane treatment and related prohibitions – equally amenable to a dynamic understanding – is especially relevant. This is because of the reality that in certain contexts, the ICRC has observed that solitary confinement, at times for prolonged periods, has been used as a disciplinary punishment for actual or perceived non-compliance with disciplinary rules by PoWs or internees with psychosocial disabilities. These detainees would violate such disciplinary rules more easily than other detainees, as their behaviour, an outward manifestation of their psychosocial disabilities, was perceived to be disruptive or dangerous. Where such confinement was imposed, mental health services in detention facilities were often inadequate.Footnote ¹⁵³ Thus, it appears that in practice, isolation does at times amount to solitary confinement – although perhaps called by a different name.

While solitary confinement, especially where it is prolonged, has been documented to negatively affect the mental health of any person subjected to it, the impact on persons with pre-existing mental health conditions when imposed for any duration is especially severe.Footnote ¹⁵⁴ It may even amount to cruel, inhuman or degrading treatment or punishment, as it often leads to psychotic symptoms and/or significant functional impairments, self-harm or even suicide.Footnote ¹⁵⁵ Furthermore, given the fact that it is resorted to where mental health services in detention facilities are inadequate, as well as for prolonged periods, it seems to be imposed not only exceptionally but rather as a result of a general sense of no other options being available.Footnote ¹⁵⁶

This in turn raises doubts in practice in this context about the implementation of isolation, including solitary confinement, purported to be a last resort with procedural safeguards. This makes a discussion of a Detaining Power's other obligations all the more compelling, as these obligations would point to alternatives which would help to avoid situations where Detaining Powers may perceive the necessity of resorting to isolation, including solitary confinement.

In particular, according to Article 30(1) of GC III and Article 91(1) of GC IV, PoWs and internees shall have the medical attention they require in PoW or internee camps. Medical attention includes appropriate mental health services which respect applicable standards of medical ethics, including the principle of voluntary and informed consent to any medical decision that may affect the individual in question.Footnote ¹⁵⁷ As the ICRC has observed, counselling and other appropriate therapies such as psychotherapy – when employed to deal with a mental health condition or psychosocial disability rather than just the associated disruptive behaviours – can be effective in decreasing such behaviours and thus avoiding the perceived need for isolation.Footnote ¹⁵⁸

To implement this obligation, advance planning to secure the availability of appropriate mental health professionals, to identify any mental health and psychosocial needs, and to secure voluntary and informed consent for any mental health intervention may be useful to avoid situations where isolation may be perceived to be necessary.

Both Article 30 of GC III and Article 91 of GC IV, as well as associated provisions, may be interpreted to promote such preparations before actual or perceived emergency situations concerning detainees with psychosocial disabilities arise. In terms of the availability of appropriate mental health professionals, medical professionals with mental health experience should either be available on-site or made available through regular visits to the detention facility.Footnote ¹⁵⁹ Where the necessary specializations are not available through these means, the two provisions also contemplate transfers for detainees with a medical condition, including a mental health condition, in order to receive the required specialized treatment from external services.Footnote ¹⁶⁰ Such transfers should only take place where the treatment in the external environment would be more favourable for the detainee concerned in light of their health condition, in accordance with applicable standards of medical ethics.Footnote ¹⁶¹ In complementarity with the CRPD, this should preclude involuntary transfers to institutions where there would be a risk that the very practices which appropriate mental health services would seek to avoid, including isolation or involuntary treatment of detainees with psychosocial disabilities, would occur.Footnote ¹⁶²

To identify any mental health and psychosocial needs as early as possible, while not explicitly foreseen by Article 30 of GC III and Article 91 of GC IV, some State practice envisages initial medical examinations of PoWs and/or civilian internees upon their arrival at a detention facility.Footnote ¹⁶³ During internment, PoWs and civilian internees also have the right to present themselves for medical examinations.Footnote ¹⁶⁴ Finally, both GC III and GC IV also obligate the Detaining Power to conduct regular medical inspections at least once per month.Footnote ¹⁶⁵

As with all medical procedures, these medical examinations and inspections are subject to applicable standards of medical ethics and in that regard must be conducted with the voluntary and informed consent of the person subjected to them; in fact, these medical examinations and inspections also present opportunities to obtain either consent or refusal for certain types of treatment in advance.Footnote ¹⁶⁶ In line with Article 12 of the CRPD, which enshrines the right of persons with disabilities to equal recognition before the law, effective measures should support the exercise of their legal capacity to express their will and preferences in relation to any future medical treatment, including regarding mental health.Footnote ¹⁶⁷

Other alternatives to isolation because of the existence of a psychosocial disability are release, repatriation, return to place of residence or accommodation in a neutral country on humanitarian grounds. These types of measures are already contemplated by GC III and its Annex I, as well as GC IV.Footnote ¹⁶⁸ Prisoners with a serious mental health condition that is either of an indeterminate character or will not be successfully treated within one year, or where their continued internment would further undermine their physical or mental health, must be repatriated or accommodated in a neutral country, unless such repatriation is against their will or accommodation in a neutral country would not improve their condition.Footnote ¹⁶⁹ GC IV contemplates special agreements between the parties to IACs for certain groups of civilian internees for release, repatriation, return to place of residence or accommodation in a neutral country on humanitarian grounds; wounded and sick internees and internees who have been detained for a long time are explicitly listed.Footnote ¹⁷⁰

In this regard, it has been suggested for PoWs that these IHL obligations should be read in light of obligations under the CRPD and that the scope of the grounds of repatriation or accommodation in a neutral country should be broadened – that these grounds should go beyond an assessment of the severity of an impairment so as to be applicable whenever basic humane conditions of detention, in particular accessibility of health care and rehabilitation, cannot be guaranteed by the Detaining Power. In this sense, repatriation or accommodation in a neutral country should be understood as a specific example of a reasonable accommodation in accordance with the CRPD.Footnote ¹⁷¹

As opposed to IHL in IAC, IHL in NIAC does not contain an explicit rule which provides for isolation, including solitary confinement, for detainees with mental health conditions or psychosocial disabilities. Therefore, this issue must be resolved with reference to the generally applicable fundamental guarantees already analyzed above, namely humane treatment and the prohibition on adverse distinction, as well as the customary IHL obligation to afford specific respect and protection to persons with disabilities. In fact, in the implementation of these rules, it is interesting to observe that the ICRC has found that certain non-State armed groups in NIAC-related detention have refrained from detaining persons with disabilities in the first place, for humanitarian and/or operational reasons. Moreover, where detentions of persons with disabilities has taken place under their supervision, some non-State armed groups have ordered their members to release detainees as soon as possible after their capture.Footnote ¹⁷² These few examples indicate that alternatives to deprivations of liberty based on impairment, whether by refraining from deprivations of liberty of persons with disabilities in the first place or through early release based on humanitarian grounds, are not merely theoretical options in conflict-related detention.
