After the Ottoman Parliament was closed by the Allies of World War I on 18 March 1920, he returned to Ankara, the capital of the nationalists (via Beirut and Silifke).

After the Republic was proclaimed on 29 October 1923, he served as a member and chief of various Independence Tribunals,[1][2] also in the one established in Diyarbakır in order to counter the Sheikh Said rebellion.
