1. Rules\Rule 42
Rule 42. Works and Installations Containing Dangerous Forces
Scope of application of the rule
When works and installations containing dangerous forces are civilian objects, they may not be made the object of attack (see Rule 7). These works and installations may only be attacked in case they qualify as military objectives (see Rule 7). Practice shows that States are conscious of the high risk of severe incidental losses which can result from attacks against such works and installations when they constitute military objectives. Consequently, they recognize that particular care must be taken in case of attack.
The detailed rules contained in Article 56 of Additional Protocol I, as well as in Article 15 of Additional Protocol II, were elaborated on the basis of this recognition.[1] These rules are set forth in numerous military manuals.[2] Attacks against works and installations which result in severe losses are offences under the legislation of a number of States.[3] Military manuals and legislation of a number of other States prohibit attacks against works and installations as such.[4]
Upon ratification of Additional Protocol I, France and the United Kingdom declared that they cannot grant “absolute” protection to works and installations containing dangerous forces which are military objectives. They recognize, however, the special peril inherent in any attack against works and installations containing dangerous forces as they require, respectively, that every “necessary” and every “due” precaution be taken in the exceptional situation where such works and installations are to be attacked, in order to avoid severe incidental losses among the civilian population.[5] The Colombian government similarly expressed the need for restraint and precaution in a statement with respect to an attack by government troops on a dam in order to dislodge guerrillas.[6]
Israel and the United States stress that the proportionality test is important in assessing the legality of an attack against works and installations containing dangerous forces which are military objectives.[7] While an assessment under the principle of proportionality must be made on a case-by-case basis, this position equally reflects sensitivity to the severe losses that may ensue among the civilian population when dangerous forces of such works and installations are released. “Launching an attack against works or installations containing dangerous forces in the knowledge that such attack will cause excessive loss of life, injury to civilians or damage to civilians objects” constitutes a grave breach of Additional Protocol I.[8] Such attacks are also offences under the legislation of many States.[9]
States’ sensitivity to the possibility of the release of dangerous forces is underscored by the fact that when attacks against such works and installations have been carried out in recent decades, the attacker stressed they were executed with the greatest care possible.[10] It is further underlined by the condemnations of such attacks, denials of such attacks and generally by the restraint shown by States with respect to attacks against works and installations containing dangerous forces.[11]
It appears, therefore, that attacks could be envisaged in situations where they are indispensable to obtain an important military advantage, which could not be obtained in any other way, and all necessary precautions are taken. The importance of such a decision, given the high risk of severe incidental losses, is illustrated by the position taken by the United Kingdom and the United States that a decision to attack a work or installation containing dangerous forces has to be taken at, respectively, “a high level of command” and “at appropriately high political levels”.[12]
State practice does not see this rule as a one-sided requirement. The defender equally has an obligation to preserve or enhance the protection of works and installations containing dangerous forces by taking all feasible precautions against attacks: the works and installations should not be used in direct support of military action; military objectives should not be located at or in the vicinity of such works and installations; and such works and installations should never be used to shield military operations.[13]
Belligerent reprisals against works and installations containing dangerous forces are discussed in Chapter 41.
The Additional Protocols have limited this rule to dams, dykes and nuclear electrical generating stations.[14] Inclusion of other works and installations containing dangerous forces could not be agreed upon at the Diplomatic Conference leading to the adoption of the Additional Protocols. However, the considerations explained above should equally apply to other installations, such as chemical plants and petroleum refineries. The fact that attacks on such installations may cause severe damage to the civilian population and the natural environment implies that the decision to attack such installations, in case they become military objectives, requires that all necessary precautions be taken when attacking them.
