This chapter identifies and examines the elements determining the legal content of any given theory of, or positive law provision for, the human right to resist. It reviews the primary triggers or conditions for activation, indicating the ‘right to resist what’, including ‘tyranny’, ‘oppression’, and ‘other violations’. It reviews the secondary triggers or conditions for activation, indicating the ‘right to resist when’, in particular the necessity condition. It also reviews both aspects of the personal scope, being the rights-holders, indicating ‘who may resist’, and also the duty-bearers, indicating ‘whose corresponding duty’. It identifies a four-fold typology of legitimate ‘object and purpose’, or ‘right to resist why’, being for human rights enforcement, for self-defence, for self-determination, and for ‘peace’ or human security. The final element examined is the material scope of application, or ‘right to resist how’, identifying three competing approaches to permissible means, and affirming proportionality limitations and other applicable limitations in international human rights law and international criminal law, as well as grounds for discretionary non-exercise. This general analytical template for identification and comparison of elements and therefore content is then applied to the evidence of legal sources of the right considered in Chapters 5–7.
