Treaty Clause Article II, Section 2, Clause 2 of the United States Constitution, includes the Treaty Clause, which empowers the president of the United States to propose and chiefly negotiate agreements, which must be confirmed by the Senate, between the United States and other countries, which become treaties between the United States and other countries after the advice and consent of a supermajority of the United States Senate.
United Nations Charter The Charter of the United Nations (also known as the UN Charter) of 1945 is the foundational treaty of the United Nations, an intergovernmental organization.[1] The UN Charter articulated a commitment to uphold human rights of citizens and outlined a broad set of principles relating to achieving ‘higher standards of living’, addressing ‘economic, social, health, and related problems,’ and ‘universal respect for, and observance of, human rights and fundamental freedoms for all without distinction as to race, sex, language, or religion.’[2] As a charter, it is a constituent treaty, and all members are bound by its articles. Furthermore, Article 103 of the Charter states that obligations to the United Nations prevail over all other treaty obligations.[1][3]
