Before the 2017 constitutional referendum, the president was not accountable for its actions and orders, except for impeachment due to high treason. All presidential decrees, except those which the president is empowered to enact on his own, had to be signed by the prime minister and the minister concerned, in accordance with the provisions of the constitution and other laws. Thus, the prime minister and the concerned ministers were accountable for these decrees, not the president. The decisions and orders signed by the president on his own initiatives may not be appealed to any judicial authority, including the Constitutional Court. The only accountability the president had was impeachment for high treason on the proposal of at least one-third of the total number of the members of the parliament and by the decision of at least three-fourths of the total number of the members.
