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	Nine Länder hold their own constitutions, parliaments and governments, but the federation retains far more legislative power than in Germany or Switzerland; much Länder activity is administering federal law (mittelbare Bundesverwaltung). Three separate high courts sit at the apex, for constitutional, administrative and ordinary matters respectively.	Presidential system with a Prime Minister, a bicameral Parliament of National Assembly and Senate under the 2023 text, and a judiciary headed by the Supreme Court.	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.
How law is made	Bills originate with the government, members of the Nationalrat, the Bundesrat or a popular initiative, and pass three readings in the Nationalrat. The Bundesrat may object but can normally be overridden. The Federal President authenticates the law, the Chancellor countersigns, and it is published in the Bundesgesetzblatt.	Bills are examined in committee and plenary and passed by the legislature, then promulgated by the President. The Constitutional Council may be seised before promulgation.	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.
Legal profession	A Rechtsanwalt qualifies through a law degree, five years of practical training including at least three in a law firm and some months at court, and the bar examination. Admission is via the regional bar chambers under the umbrella of the Österreichischer Rechtsanwaltskammertag. Notaries are a separate profession with appointments limited in number.	Avocats admitted through the Ordre des avocats du Tchad; the profession is concentrated in N'Djamena.	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 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.
