The need for consistency is identified regularly in the literature on the persistent objector rule, but this is often implicit or amalgamated/confused with the persistence criterion. This chapter aims to confirm the need for consistent objection, which is a requirement related to, but distinct from, persistence. It then assesses the rationale for the consistency criterion, before turning to the important question of what ‘consistent objection’ in fact entails. The chapter then considers whether a state's objections must be ‘absolutely consistent’ (in the sense of any contrary practice being terminal for its exemption from the relevant norm), or whether a generally consistent pattern of objection will suffice. The chapter also asks whether the silence of a state — in circumstances where it might reasonably be expected to object — can be interpreted as inconsistent practice. Finally, the chapter considers the notion of ‘substantive consistency’, meaning the consistency of a state's position as between related norms: does a persistent objector need to have a principled stance of objection across comparable norms?
