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.

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.	Unitary, with meaningful local autonomy under the Local Autonomy Act: 17 first-level divisions with directly elected governors, mayors and councils. Local ordinances must not contravene statute, and the central government retains extensive supervisory powers. There is no federal division of legislative competence.
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 government or by ten or more members of the Assembly. They go to a standing committee, then to the Legislation and Judiciary Committee for legal scrutiny, then to plenary. The President may veto a bill within fifteen days, and the Assembly may override with two-thirds of members present and a majority of those on the roll. A 2012 amendment to the National Assembly Act — the so-called Assembly Advancement Act — requires a three-fifths supermajority to bring most contested bills to a vote, which materially raises the threshold for legislating.
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.	Unified: an attorney-at-law (변호사) may appear at every level. Since 2009 the route is a three-year professional law school degree followed by the bar examination, replacing the old system of a single national examination and two years at the Judicial Research and Training Institute; the old route closed fully in 2017. Judges and prosecutors are now recruited from practising lawyers rather than straight from training. The Korean Bar Association regulates admission and discipline.

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.
