This article examines the constitutional and international legal issues that would result from a state unilaterally terminating Memoranda of Understanding (MoUs) with Turkey and Azerbaijan. The sudden termination of a memorandum of understanding (MoU) can have far-reaching implications, both domestically and globally, despite the fact that it is commonly considered to be a non-binding agreement. This article investigates the ways in which such cancellations may pose a threat to constitutional frameworks, especially the roles that the executive branch and the legislative play in matters pertaining to international relations. It also takes into account the way in which international law evaluates the legality and enforceability of memorandums of understanding, as well as the potential diplomatic repercussions. By doing this research, the goal is to shed light on the political realities and legal norms that are associated with the unilateral termination of international accords.
