Final answer:
Iran's judiciary is unique due to the integration of Islamic law and the strong influence of the Supreme Leader, in contrast to the common law system of the U.S.
Step-by-step explanation:
The judiciary in Iran is unique due to its integration of religious law and a Supreme Leader with significant influence over the courts. Unlike the dual court system of the United States, where federal and state courts have separate jurisdictions and the Supreme Court is the highest appellate court, Iran's judicial system is characterized by the incorporation of Islamic Sharia law and is overseen by the Supreme Leader.
This system attempts to blend elements of theocracy and democracy, even often being described as paradoxical, as it functions within a predominantly religious framework while also having seemingly democratic structures. What makes Iran's judiciary particularly distinct is the way it entwines religious doctrine with civil governance, resulting in a legal system that is significantly different from the common law or civil law systems seen in many other nations.
