Among many agreements, there was a separate agreement with the United States, the Chester concession. In the United States, the treaty was opposed by several groups, including the Committee Opposed to the Lausanne Treaty (COLT), and on 18 January 1927, the United States Senate refused to ratify the treaty by a vote of 50–34, six votes short of the two-thirds required by the Constitution.[22] Consequently, Turkey annulled the concession.[2]
