The University Senate was established by the trustees after a university-wide referendum in 1969. It succeeded to the powers of the University Council, which was created in 1890 as a body of faculty, deans, and other administrators to regulate inter-Faculty affairs and consider issues of university-wide concern. The University Senate is a unicameral body consisting of 107 members drawn from all constituencies of the university. These include the president of the university, the provost, the deans of Columbia College and the Graduate School of Arts and Sciences, all who serve ex officio, and five additional representatives, appointed by the president, from the university's administration. The president serves as the Senate's presiding officer. The Senate is charged with reviewing the educational policies, physical development, budget, and external relations of the university. It oversees the welfare and academic freedom of the faculty and the welfare of students.
