5.7.1 Testing protocol
Rules of IHL attempt in broad terms to regulate conflict in order to minimize human suffering. IHL reflects this constant balance between the military necessity arising in a
45
state of war and the needs for humanitarian protection. IHL is founded upon the following principles;
- distinction between civilians and combatants - prohibition of attacks against those hors de combat - prohibition on the infliction of unnecessary suffering - principle of proportionality
- notion of necessity - principle of humanity
Each principle should be found within the specific rules and norms of IHL itself, but the principles may also help interpretation of the law when the legal issues are unclear or controversial. Depending on the issue, they balance between the principles and interest shifts. For example, during hostilities, military necessity may limit the notion of humanity by allowing for destruction, but in other situations such as the protection of the wounded and sick, the principle of humanity is at the heart of the legal rules.
(a) The principle of distinction between civilians and combatants
The principle of distinction underpinning many rules of IHL is that only fighters may be directly targeted. This is a necessary compromise that IHL provides for in order to protect civilians in armed conflict. Without the principle of distinction, there would be no limitation on the method‟s of warfare.
The principle of distinction is set out in Article 48 and 52 of Additional Protocol 1 to the Geneva Conventions. Any direct attack against a civilian or a civilian object is not only a violation of IHL but also a grave breach. Direct attacks against civilians and/or civilians objects are categorized as war crimes. Additionally, any weapon which is
46
incapable of distinguishing between civilians/civilian objects and fighters/military objects is also prohibited under IHL. The principle is also a rule of Customary International Law, binding on all states.
(b) The prohibition of attacks against those horse de combat.
The prohibition to attack any person horse de combat (those who are sick and wounded, prisoners of war) is a fundamental rule under IHL. For example, while a soldier could be targeted lawfully under normal circumstances, if that soldier surrender or is wounded and no longer poses a threat, then it is prohibited to attack that person.
Additionally, they may be entitled to extensive protection if they meet the criteria of being a prisoner of war.
(c) The prohibition on the infliction of unnecessary suffering
While IHL does not permit violence, it prohibits the infliction of unnecessary suffering and superfluous injury. While the meaning of such terms is unclear and the protection may as such be limited, even fighters who may be lawfully attacked are provided protection by this prohibition. One rule that has been established based on this principle is the prohibition on the use of blinding laser weapons.
(d) The principle of proportionality
The principle of proportionality limits and protects potential harm to civilians by demanding that the least amount of harm is caused to civilians, and when harm to civilians must occur, it needs be proportional to the military advantage. Article 51(5)(b) of API prohibits attacks when the civilian harm would be excessive in relation to the military advantage sought. The principle cannot be applied to override specific
47
protections, or create exceptions to rules where the text itself does not provide for one. As with the principle of necessity, the principle of proportionality itself is to be found within the rules of IHL themselves. For example, direct attacks against civilians are prohibited and hence a proportionality assessment is not a relevant legal assessment as any direct attack against even a single civilian who is not taking part in hostilities is a clear violation of IHL. Proportionality is only applied when a strike is made against a lawful military target.
(e) The Notion of Necessity
A dominant notion within the framework of IHL is military necessity. This principle mostly clash with humanitarian protection. Military necessity permits armed forces to engage in conduct that will result in destruction and harm being inflicted. The concept of military necessity acknowledges that under the laws of war, wining the war or battle is a legitimate consideration.
However, the concept of military necessity does not give the armed forces the freedom to ignore humanitarian considerations altogether and do what they want, it must be interpreted in the context of specific prohibitions and in accordance with other principles of IHL.
(f) The Principle of Humanity
The principle of humanity, and its absence during the battle of Solferino of 1859, was the central notion that inspired the founder of the International Committee of the Red Cross (ICRC), Henry Dunant. The principle stipulates that all humans have the capacity
48
and ability to show respect and care for all, even their sworn enemies. The notion of humanity is central to the human condition and separates humans from animals
IHL, simply looks to limit the harm, and the principle of humanity is very much at the heart of this ambition. Many rules of IHL are inspired by this notion, specifically those setting out protections for the wounded and sick.
