Comparison
Read two legal systems against each other
Because every portal follows the same fifteen-section outline, the comparison is genuinely like-for-like rather than a collage of whatever each government happens to publish.

| Population | 89,000,000 | 130,000,000 |
| Division of powers | Unitary, with 31 provinces headed by governors-general appointed by the Interior Ministry, alongside elected city and village councils created by the Constitution and operating since 1999 with limited competences. | Federal. Powers not expressly granted to the union are reserved to the 32 states (Article 124). States run their own civil, family and criminal-enforcement codes, but criminal procedure, labour and commercial law were federalised to produce single national codes. |
| How law is made | A bill is introduced by the Government or by at least fifteen deputies, passes the Majlis, and goes to the Guardian Council, which has ten days, extendable, to find it consistent with Islam and the Constitution. If the Council objects, the bill returns for amendment; persistent disagreement goes to the Expediency Discernment Council, whose decision is final. Only then does the President sign and publish. | Bills may be introduced by the President, either chamber, state legislatures or by citizens with 0.13% of the electoral roll. Both chambers must pass an identical text; the President may veto, and Congress overrides with two-thirds of each chamber. Constitutional amendments need two-thirds of Congress plus a majority of state legislatures (Article 135). |
| Legal profession | Two parallel routes to practice, which is unusual and consequential: attorneys licensed by the Iranian Bar Association (Kanoon-e Vokala), a self-governing body dating to 1953, and attorneys licensed under Article 187 of the Third Development Plan directly by the judiciary. The two groups have contested each other's standing for two decades. Notaries operate licensed offices under the registration organisation, and their authentication is required for property transfers, marriage contracts and powers of attorney. | A law degree plus a cédula profesional from the Education Ministry licenses practice; there is no compulsory bar examination or single mandatory bar, which distinguishes Mexico from most of the region. Notaries public are a separate, strictly limited state-appointed profession with exclusive competence over real estate and company deeds. |
A comparison table flattens nuance by design. Where a difference matters to a decision you are making, open both portals and read the section in full — the constitutional detail behind a one-line summary is often the part that governs the outcome.
