The way in which international law has been constructed and reconstructed over the ages in favour of the Western countries has driven some Third-World scholars to perceive international law as 'a global law made by the West' for the purpose of controlling global undertakings. In the past, international law was used by the Westerners to legitimise colonialism and all their acts of exploitation in the developing countries. In the modern period, international law is predominantly used to protect, project and promote (3Ps) the interest of the Westerners. This includes their multinational businesses scattered globally, and protectionist bid against terrorist attacks. This paper uses theoretical, critical and multidisciplinary approaches to examine this perception of international law. It concludes that construction and reconstruction of international law in favour of Western countries has been one key instrument that perpetuate severe inequality between the Global North and Global South, which in turn hampers efforts toward global-peace and security.
