From Withdrawal from International Agreements: Legal Framework, the Paris Agreement, and the Iran Nuclear Agreement (R44761, May 4, 2018):
The legal procedure through which the United States withdraws from treaties and other international agreements has been the subject of long-standing debate between the legislative and executive branches. Recently, questions concerning the role of Congress in the withdrawal process have arisen in response to President Donald J. Trump’s actions related to certain high-profile international commitments. This report outlines the legal framework for withdrawal from international agreements under domestic and international law, and it applies that framework to two pacts that may be of significance to the 115th Congress: the Paris Agreement on climate change and the Joint Comprehensive Plan of Action (JCPOA) related to Iran’s nuclear program.
