The crude oil file in Iraq is the biggest and most concerning problem faced by consecutive Iraqi governments formed since 2003, due to the importance of this file at the national level. Perhaps the most significant part of the complexity that permeates this file is the conflict between the Federal Central Government and the Territorial Government, which is nurtured mainly by opposing legal and political perspectives resulting from viewing the constitutional texts of the 2005 Iraq's Federal Constitution from different angles. These differences caused huge imbalances and led to many conflicts between the two parties. Therefore, we need a deep understanding of the root causes of this issue in order to present effective legal solutions to the management of this file.
