2017 constitutional referendum extended the president's accountability beyond impeachment due to high treason. According to the constitutional amendments approved in the said referendum, the Grand National Assembly may initiate an investigation of the president, the vice president or any member of the Cabinet upon the proposal of simple majority of its total members, and within a period less than a month, the approval of three-fifths of the total members. The investigation would be carried out by a commission of fifteen members of the Assembly, each nominated by the political parties in proportion to their representation therein. The Commission would submit its report indicating the outcome of the investigation to the speaker within two months. If the investigation is not completed within this period, the Commission's time renewed for another month. Within ten days of its submission to the speaker, the report would be distributed to all members of the Assembly, and ten days after its distribution, the report would be discussed on the floor. Upon the approval of two-thirds of the total number of the Assembly by secret vote, the person or persons, about whom the investigation was conducted, may be tried before the Constitutional Court. The trial would be finalized within three months, and if not, a one-time additional period of three months shall be granted.
