This chapter examines UN Security Council practice with respect to the use of force in no-fly zones and maritime exclusion zones. It considers whether the law governing the zone is based or not based on the law of armed conflict (LOAC) and whether the law on the use of force inside the zone is essentially the same as that outside it. It also assesses the effect of the Security Council’s act of declaring or acquiescing in the zone on the law that is normally applicable in the ocean or airspace enclosed by the zone. The chapter also analyses whether the Security Council can authorize the use of lethal force for the purpose of enforcing a mandate despite the absence of LOAC authorization. It discusses the notion of a ‘third paradigm’ for use of lethal force and the concept of ‘self-defence’ endorsed by the Security Council (and the UN more generally).
