State Sovereignty is an inherent power of a State and a principle of international law for which no derogation is allowed. Although it is an exclusive right of States, however, these powers can be shared or donated to international institutions by States when they decide to setup international institutions for their benefits. No matter the method in which the powers are transferred to the institutions, even where the agency relationship is maintained between the States and international institutions, the States are the principal while the institutions are the agents
of the States. As good as these may sound, it has been discovered that international institutions do not limit their activities to the
enabling instruments that set them up. The activities of the overzealous international institutions conflict with the principles
of non-intervention in domestic affairs of member States as provided in the United Nation Charter. It is therefore recommended that international institutions restrict their functions and activities to the enabling instruments setting them up. The conditionalities of international institutions which go to
whittle down the Sovereignty of Member States must be discouraged by including appropriate checks and balances in the enabling instruments or articles of agreement.
Key words: International Institutions, State Sovereignty, and Non-Intervention.
