International armed conflict |
---|
The law of international armed conflict (IAC) applies to any armed confrontation between two or more States.[1] Some scholars have suggested that the fighting must be of a certain intensity before international humanitarian law (IHL) comes into effect,[2] but the prevailing view is that any “resort to armed force between States”,[3] however brief or intense, triggers the application of IHL.[4] The law does not prescribe any specific form for the resort to force.[5] Consequently, the hostilities between the belligerent States may involve any combination of kinetic and cyber operations, or cyber operations alone.[6]
It is unclear what effect would cyber operations unaccompanied by any use of kinetic force have to have in order for IHL to apply. Although it is generally accepted that if cyber operations have similar effects to classic kinetic operations and two or more State actors are involved, the resulting situation would qualify as an IAC,[7] the law is unsettled on whether cyber operations that merely disrupt the operation of military or civilian infrastructure amount to a resort to armed force for the purposes of IHL.[8] In the cyber context, States often act through non-State intermediaries and proxies (see also attribution). If that is the case at the outset of an armed confrontation, the relevant State must exercise sufficient degree of control over the non-State entity that commences hostilities against another State for the situation to qualify as an IAC. However, the correct legal test to use in this regard is subject of an ongoing controversy.[9] Two specific standards have emerged in international jurisprudence. The higher of the two is the “effective control” test, which requires that the State must exercise control over the entire course of the operations in question.[10] By contrast, the “overall control” test is less demanding, requiring only that the State provides some support and that it participates in the organization, co-ordination, or planning of the relevant operations.[11] According to the now prevailing view, the “effective control” test is the controlling test for the purposes of attribution under the law of State responsibility, but the “overall control” test is the correct one for conflict qualification under IHL.[12] This is also confirmed by decades of consistent practice by international criminal tribunals including the ICTY, the ECCC, and the ICC.[13] |
