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 | Power is concentrated in the Supreme Pontiff, exercised through the Pontifical Commission for Vatican City State (legislative), the Governorate (executive) and the Vatican tribunals (judicial). | The executive sits inside the legislature. Judicial independence was strengthened in 2005 when the Supreme Court replaced the Appellate Committee of the House of Lords. |
| How law is made | Laws are prepared by the Pontifical Commission and take effect with the Pope’s approval, published in the Acta Apostolicae Sedis supplement. | First reading, second reading, committee stage, report stage and third reading in each House, then ping-pong on amendments, then Royal Assent. |
| Legal profession | Advocates are enrolled with the Vatican tribunals; canon lawyers (canonists) practise before ecclesiastical courts. | A split profession: solicitors (regulated by the SRA) advise and conduct litigation; barristers (Bar Standards Board) hold rights of audience in the higher courts. |
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.
