Second, under Article 175 of the Constitution and Article 94 of the National Assembly’s Rules of Procedure,8 the voting had to take place by secret ballot. Indeed, Article 175 of the Constitution stipulates that “the adoption of a proposal for an /constitutional/ amendment shall require a three-fifths majority of the total number of members of the Assembly by a secret ballot”. The Rules of Procedure of the Grand National Assembly of Turkey specify that for the purpose of a secret vote, “three circular ballot papers, one white, one green and one red, are simultaneously given to each deputy. The circular ballot paper to be used in voting shall be placed into the related box. The other two are left at the indicated space” (Article 148).
