In case of a dispute among citizens...
In case of a dispute among citizens, or among organs, or between the citizens and the government, as well as in relation to the violation of the rights of people, the only authorized agency to adjudicate, attend to and adapt laws to those cases is the judicial power. Mere ratification of laws in parliament cannot solve any problem, because in times of dispute and discord, everyone deems himself rightful and interprets the law in his favor. 3.
Executive power Undoubtedly, In order to achieve its objectives, society is in need of law, but all people do not observe the laws. In fact, there are various motives to violate them. The law needs an executive power which possesses sufficient clout to implement the rules and regulations. The executive power is expected to implement laws, deter violations and implement judicial decrees passed in judicial courts.
Along this line, if naked force is needed to implement laws and punish violators and criminals, disciplinary forces can be employed. We briefly stated the theory of separation of powers in democratic and popular systems.
We do not intend to explain the Islamic viewpoint on the theory of separation of powers but we deem it necessary to note that in the Constitution of the Islamic Republic of Iran, the principle of separation of powers has been accepted, while the principle of wilayah al-faqih , which emanates from the Islamic nature of the system, serves as the point of connection between the powers.
Legitimacy of powers in the Islamic system lies in the Islamic and divine structure, and in a sense in their connection to the Origin of creation, but wilayah al-faqih is the system’s link to God and its basis of legitimacy.
Once we talk about the enactment and implementation of laws in the realm of Islamic political system and claim that the aggregate of approved laws and rules should be Islamic and religious, we make it clear that Islam is concerned not only with issues pertaining to prayer and fasting, worship and supplication, but it is a comprehensive code of life that embraces social law, corporate law, civil law, commercial law, international law and other laws needed by society.
Thus, as principle and rule, we have accepted that Islam has social laws that bind the government to regard them as credible and strive to implement them. According to Islam if a government neither regards the laws of Islam as credible, nor strives to implement them, it is an illegitimate government.
