All entities to which the international community recognizes subjectivity under international law are subjects of international law. These are primarily states. Subjectivity under international law implies that an entity, as a person, is the bearer of international rights and obligations (according to international law) and that it is directly subject to the international legal order. These are legal entities with the legal capacity to possess international rights and international obligations and responsibilities, and especially the ability of persons to sue, contract and conclude international agreements and join international organizations, to acquire and dispose of property, have international immunities and privileges, represent is diplomatic, and performs all other international legal acts, as well as legal processes and affairs inherent in such legal entities. According to Article 1 of the Montevideo Convention, “A State, as a person under international law, must have the following characteristics: a) permanent population; b) defined territory; c) authority; and d) the ability to build relations with other States." Recently, as the power of supranational institutions grows, many people (especially proponents of the constitutive theory of international law) reject the notion of sovereignty as outdated and view the state only as a unit of political division of the world.
