About one month before the May 27 coup d'état, a protest, initiated by university students in Ankara, was held in Istanbul following the decision to establish an investigation commission in the Turkish Grand National Assembly. The attitude of the government to this demonstration was tough and a martial law was proclaimed. The Istanbul and Ankara martial law administrative brought bans with the communiqués published and closed some newspapers for a certain period of time. According to the deputy Adnan Menderes, these protests were organized by a superior intelligence and were trying to move against the ruler by deceiving people with completely false news. After the street actions that could not be controlled, the May 27th coup took place. Prosecutors in DP Yassıada courts were counted among the judges on charges of violation of the Constitution and the asylum seekers living in the Istanbul-Ankara incidents. As a result of the judgments, Adnan Menderes, Fatin Rüştü Zorlu and Hasan Polatkan were executed for the constitutional violation.
