ABSTRACT
This chapter draws inspiration from the thesis propounded by Rolando Quadri which holds that principles of international law, being the immediate and direct expression of the will of the international community, are rules of general international law. It describes an ongoing evolutionary process, by using the term verticality with reference to changes in the structure of the international community. Since the 1990s, several new rules of general international law have been added to international human rights law. The principle of collective humanitarian intervention emerged at the behest of powerful states with the help of UN organs, and civil society, which supported its authority. To illustrate, on the occasion of those crises, at the behest of the hegemonic powers, there emerged a procedural principle allowing states to use force in order to re-establish peace and protect fundamental global interests, provided that the force is used on behalf of the international community and with the authorization of the Security Council.
