Abstract [en]

Traditionally, international humanitarian law (IHL) is conceptualized as a body of mutually binding, horizontal international legal rules that are agreed upon by States and that govern the relationships between parties to armed conflicts. Yet, there is discernible evidence that contemporary IHL – and the broader normative environment that pertains to the regulation of armed conflicts in which it is situated – is incorporating elements of unilateralization, manifested in legal and non-legal norms that regulate armed conflicts taking the form of commitments whose validity is not dependent on being reciprocated. This article examines some of the systemic implications of unilateralization of IHL and considers its pitfalls and potential.

Abstract [en]

Against the background of a significant number of compliance mechanisms that the law of armed conflict (LoAC) provides for, on the one hand, and the fact that violations remain a pervasive feature of contemporary armed conflict, on the other, the present chapter examines five distinct compliance-related clusters. It begins by a reminder of the various existent compliance mechanisms and a plea for an honest, inter-disciplinary stocktaking of their efficacy. This is followed by another plea, namely for contextualizing compliance and compliance mechanisms and for moderating the expectations as to what they can achieve as counterweights to the myriad of factors that are prevalent in armed conflicts and that cause violations of the LoAC. The chapter then proceeds with addressing three particular trends that pose particular challenges in relation to compliance: the prevalence of non-international armed conflicts; that the current discourse about compliance is dominated by a culture of repression rather than prevention; and that compliance is increasingly individualized at the expense of addressing the collective nature of the violence inherent in armed conflict as the context in which violations occur.

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.
