The Prespa Agreement (Greek: Romanized: Symfonia ton Prespon, Macedonian: , Romanized: Prespanski Dogovor), also known as the prespes agreement, the Prespa agreement or the Treaty of Prespa, is an agreement reached on 12 June 2018 between Greece and the Republic of Macedonia under the aegis of the United Nations and which has established a long-standing dispute over the name of the Republic of Macedonia. In the end, the reference to erga omnes in the Prespa agreement serves only a descriptive function that does not have concrete legal consequences but merely states that “the agreed solution [name of the name] must serve all international objectives of state representation.”  International law is no stranger to the descriptive use of the Erga Omnes concept. In the case of nuclear tests, for example, the ICJ stated that France`s unilateral declarations on stopping atmospheric nuclear tests were binding on it because they were “made public and erga omnes”.  In this case, the use of the term exclusively described to which the statements were addressed and the absence of direct legal consequences result from the fact that they were addressed to erga omnes, in addition to the realisation that France was obliged not to conduct atmospheric nuclear tests with respect to each state in the international community.  This prominent use of Erga omnes in the Prespa agreement appears all the more inappropriate when one considers the commitments that North Macedonia has to fulfill the promise of the omnes erga regarding its new official name. Specifically, in addition to the obligation not to use any other name in the implementation of its international relations, the means to achieve the ambitious goal of achieving the use of the new official name by other states and by all international organizations and institutions are limited to a rather light and light obligation of behaviour (i.e. due diligence to simply notify and request that name). (Article 1, paragraph 6, points a) and b). This commitment is much lower than the commitment made by the parties to the Prespa agreement with regard to irredentist claims and propaganda activities when the parties commit to preventing, preventing and repressing such phenomena (Articles 3 and 6 of the agreement).
