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.

| System of government | Unitary Islamic absolute monarchy | Constitutional monarchy |
| Constitution | Basic Law of Governance | Constitution of the Independent State of Papua New Guinea |
| In force since | 1992 | 1975 |
| Capital | Riyadh | Port Moresby |
| Official languages | Arabic | English, Tok Pisin, Hiri Motu |
| Currency | Saudi riyal (SAR) | Papua New Guinean kina (PGK) |
| Population | 36,900,000 | 10,300,000 |
| Division of powers | Unitary. Thirteen provinces headed by governors drawn from the royal family and appointed by the King, each with an appointed provincial council. No legislative competence exists below the national level. | Decentralised but not federal. Twenty-two provinces, including the National Capital District, have provincial governments with limited legislative power under the Organic Law on Provincial Governments and Local-level Governments 1995. The Autonomous Region of Bougainville has a distinct constitutional status: its 2019 non-binding referendum returned 97.7% for independence, and the Constitution was amended in 2024 to provide a ratification pathway. |
| How law is made | There is no legislature with power to enact law. Proposals originate in ministries or the Shura Council, are considered by the Council of Ministers, and take effect as royal decrees signed by the King and published in Umm al-Qura. The Shura Council may study and recommend but its resolutions require royal approval, and the King may legislate without consulting it. | Bills pass through three readings in the single chamber and receive the Governor-General's assent. Constitutional amendments must be published in advance, and depending on the provision require an absolute majority, two-thirds or three-quarters of all members, voted on at two sittings at least two months apart. Organic Laws follow the same entrenched process. The Speaker certifies that the constitutional requirements were met, and failure to follow them has led the Supreme Court to strike amendments down. |
| Legal profession | Advocates are licensed under the Code of Law Practice and must be Saudi nationals to appear in court, though licensed foreign firms may advise and now associate more freely following the 2024 opening. Judges are appointed from graduates of Sharia faculties by the Supreme Judicial Council and the King. Notarisation is a judicial function performed by notaries within the Ministry of Justice, and most commercial documentation must be executed in Arabic to be enforceable onshore. | A fused profession under the Lawyers Act 1986: lawyers are admitted by the National Court and hold an unrestricted or restricted practising certificate issued by the Papua New Guinea Law Society. Most qualify through the University of Papua New Guinea law degree and the Legal Training Institute's practical course. The Law Society regulates admission and discipline, and the Public Solicitor is the main provider of representation for those who cannot pay. |
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.
