The law of international responsibility sets out the legal consequences arising from a breach by a State of its international obligations. It should be distinguished from ‘primary rules’ of international law, which lay down international obligations. International responsibility arises when a certain act or omission is wrongful, ie it is attributed to a State and it amounts to a violation of its ‘primary’ obligations. The international responsibility may be excused under certain strict circumstances, such as consent or necessity. Otherwise, the responsible State should cease the wrongful conduct and, in case of damage, it should provide reparation to the injured State, in the form of restitution, compensation, and satisfaction.
