Abstract [en]

The "organization" of the non-State armed group and the "intensity" of the violence between it and its opponent(s) have emerged as the two key criteria to determine the temporal scope of the law of non-international armed conflict. These criteria have served to lift the fog of law in some important respects. Yet, several aspects of the temporal scope of the law of non-international armed conflict remain unsettled. This article addresses three of them, namely the assertion that the factors for ascertaining organization and intensity that have evolved in the jurisprudence of international criminal courts and tribunals are indicative rather than determinative, to whom the criterion of organization is to be applied, and whether the requisite level of intensity of armed violence can be cumulative when multiple organized armed groups are pitted against each other and government forces even though the armed violence that arises in the bilateral relations between two opposing parties does not reach the requisite level of intensity.

Abstract [en]

The International Law Association Study Group on the Conduct of Hostilities in the 21st Century was established in 2011 and held its first meeting in 2012. The Study Group has explored numerous issues arising from the relationship between international humanitarian law (IHL) and international human rights law in the conduct of military operations, technological challenges posed by new weapons systems, and the basic principles of IHL in the conduct of hostilities. In 2015, the Study Group established three working groups focusing on core issues within IHL in relation to the conduct of hostilities in modern warfare. These working group topics were military objectives, the principle of proportionality, and precautions in attacks. Each of these working group reports contributed to this final report, which the Study Group presented at the 77th International Law Association Conference in Johannesburg, South Africa on August 7–11, 2016.

Abstract [en]

Advances in technologies that could endow humans with physical or mental abilities that go beyond the statistically normal level of functioning are occurring at an incredible pace. The use of these human enhancement technologies by the military, for instance in the spheres of biotechnology, cybernetics and prosthetics, raise a number of questions under the international legal frameworks governing military technology, namely the law of armed conflict and human rights law. The article examines these frameworks with a focus on weapons law, the law pertaining to the detention of and by “enhanced individuals,” the human rights of those individuals and their responsibility for the actions they take while under the influence of enhancements.
