The legislature of Islamic republic of Iran (Persian: قوه مقننه جمهوری اسلامی ایران) consists of two components, a unicameral[1] parliamentary chamber called Islamic Consultative Assembly and a reviewing power, the Guardian Council of the Constitution which is more powerful.
[2] According to article 93 of the Constitution of the Islamic Republic of Iran, the Parliament generally has no legal status without the simultaneous existence of the Council.
As a consequence, existence of the Council is a precondition for the efficiency of the legislative power as all bills passed by the Parliament have to be summitted to the Council in order to enact.
[2] The council has the authority to veto the bill if it finds it incompatible with sharia or the constitution.
[2] In case that the Parliament and the Council dispute over a blocked bill and refuse to accept positions by each other, the bill is submitted to the Expediency Discernment Council of the System, set up to resolve the conflicts.
