Dangerous Orbits : Applying the Law of Self-defence to Hostile Acts Against Satellite Systems

Abstract: The world has found itself in the unsatisfactory position of depending greatly upon the services of satellites, all while the risk of satellites becoming targets during conflict looms ever greater. This paper assesses the lex lata of the law of self-defence as enshrined in the Charter of the United Nations, focusing on the rationae materiae aspect of the armed attack concept. It thereafter applies general conclusions in this regard to the specific context of hostile acts against satellite systems, with an aim to clarify under what conditions such hostile acts justify the exercise force in self-defence.
