It is good to recall that the work of elected representatives in Tunisia took two years, three months and three days to complete the drafting of the new Const. Oct. 23, 2011, when the National Constituent Assembly (NCA) was elected, until Jan. 26, 2014, the constitution was being written word by word, article by article. This occurred under the watchful eyes of observers and civil society, under the spotlight of the media and commentators and sometimes under pressure from the street and the echoes of public opinion.
Anyhow, I think this text does worth reading and learning. There are many innovative formulations for protection of the state from return of authoritarianism..for instance look at the Art. 17, 18 AND 19 On military and security forces: It stipulates that these forces ‘HAVE TO REMAIN IMPRATIAL TOTALLY’. When we compare this with the place of army and revolutionary guards in the Islamic Republic of Iran's constitutional system we can easily understand how significant is this clause. The Art. 144 of the post revolutionary Iranian Const. of 1980 provides that "The Army of the Islamic Republic of Iran must be an Islamic Army, i.e., committed to Islamic ideology and the people, and must recruit into its service individuals who have faith in the objectives of the Islamic Revolution and are devoted to the cause of realizing its goals." Art. 150 stiplutes "The Islamic Revolution Guards Corps, organized in the early days of the triumph of the Revolution, is to be maintained so that it may continue in its role of guarding the Revolution and its achievements. The scope of the duties of this Corps, and its areas of responsibility, in relation to the duties and areas of responsibility of the other armed forces, are to be determined by law, with emphasis on brotherly cooperation and harmony among them."
