Among many agreements was a separate agreement with the United States, the Chester concession. In the United States, the treaty was rejected by several political groups, including the Committee against the Treaty of Lausanne (COLT), and on January 18, 1927, the U.S. Senate refused to ratify the treaty by 50 votes to 34, six votes less than the two-thirds requested by the Constitution.  As a result, Turkey cancelled the concession.  Turkey also waived its privileges in Libya, defined in 1912 by Article 10 of the Treaty of Ouchy (in accordance with Article 22 of the 1923 Treaty of Lausanne).  A secret annex to the Treaty, called the “Declaration of Amnesty,” gave the perpetrators immunity for all crimes committed between 1914 and 1922, in particular the Armenian Genocide, assyrian genocide and Greek genocide, which were then illegal under international law.   The treaty thus put an end to efforts to prosecute Ottoman war criminals.   Thus, the treaty codified impunity for the Armenian genocide.  A secret annex of the treaty granted immunity to Turkish perpetrators for crimes committed between 1914 and 1922, in particular the Armenian genocide.
Turkey has also officially surrendered all claims on the Dodecanese Islands (Article 15); Cyprus (Article 20);  Egypt and Sudan (Article 17); Syria and Iraq (Article 3); and (with the Treaty of Ankara) to regulate the borders of these last two nations.  The territories in southern Syria and Iraq in the Arabian Peninsula, which were still under Turkish control when the Mudros ceasefire was signed on 30 October 1918, were not explicitly identified in the text of the treaty. However, the definition of Turkey`s southern border in Article 3 also meant that Turkey had officially ceded it. These areas included the mutawakkilite kingdom of Yemen, Asir and parts of Hejaz, such as the city of Medina. They were held by Turkish forces until 23 January 1919.   By Articles 25 and 26 of the Treaty of Lausanne, Turkey officially ceded the danube island of Adakale to Romania by formally recognizing the corresponding provisions of the 1920 Treaty of Trianon.   Following a diplomatic irregularity at the Berlin Congress in 1878, the island remained technically part of the Ottoman Empire.
