The Iranian legal system is primarily based on Islamic law, also known as Sharia, which influences both civil and criminal law. It operates under a combination of Islamic principles and civil law, with the Islamic Republic of Iran established after the 1979 revolution. The system includes various courts, such as Islamic courts and civil courts, which handle different types of cases. Judges in the Iranian legal system are often trained in Islamic jurisprudence and have significant discretion in interpreting laws. The Supreme Court serves as the highest judicial authority, ensuring that laws align with Islamic values and the Constitution of Iran.
