Justice and public safety in Singapore
Singapore is a unitary, common-law city-state with all justice functions national. Its most distinctive feature is that the Attorney-General is at once the Government's legal adviser and the Public Prosecutor. It has a single national judiciary topped by the Court of Appeal, diffuse constitutional review with no constitutional court, and police and prisons both under the Ministry of Home Affairs — and, recorded honestly, no general ombudsman, no national human-rights institution, and no independent police-complaints body.

Singapore is a unitary, common-law sovereign city-state. The Constitution vests judicial power in a single Supreme Court and such subordinate courts as written law provides (Article 93), and establishes one Legislature — there is no federal, state or provincial tier, and no distribution-of-powers lists. So all four justice functions sit at the national level, and judicial independence is protected by tenure and a removal procedure requiring a tribunal of Supreme Court judges (Article 98).
The system runs through national institutions: a single judiciary topped by the Court of Appeal, the Attorney-General as Public Prosecutor, the Singapore Police Force, and the Singapore Prison Service — the last two both under the Ministry of Home Affairs. Constitutional review is diffuse, decided by the ordinary Supreme Court, with no dedicated constitutional court.
Jurisdictions modelled
A territory can exist administratively without being a separate legal jurisdiction. This table records, for each modelled tier and territory, whether it has its own arrangement for a function, whether the function is organised nationally, or whether we have simply not researched it.
| Jurisdiction | Level | Courts | Prosecution | Policing |
|---|---|---|---|---|
| Singapore | country | own | own | own |
unknown means not researched. It is never a synonym for none: an unresearched territory does not inherit the metropolitan arrangement.
What has not been researched
These areas have no page. That is a statement about our research, not about Singapore: each of these institutions exists, and we have simply not established enough from primary sources to write about it responsibly.
- Forensic systemNot researched
- The organisation of forensic science in Singapore (the Health Sciences Authority's forensic services) has not been read to the standard required, and forensics is a safety-sensitive section where an under-sourced description is specifically forbidden.
- Border and customsNot researched
- Border and customs in Singapore involve the Immigration & Checkpoints Authority and Singapore Customs, and could not be researched to the standard required here without risking an inaccurate description of a security-adjacent function.
- Institutional historyNot researched
- Singapore's institutional history — independence in 1965, the reception of English common law, the end of Privy Council appeals, and the 2019/2021 restructuring of the Supreme Court — cannot be written responsibly from general knowledge and requires scholarly and archival sources not consulted here.
- Institutional timelineNot researched
- A timeline requires each milestone to carry its own verified source and date. The dated facts established in this pilot — independence in 1965, the 2019/2021 Supreme Court restructuring — are a start, but a responsible timeline needs primary sources for each milestone, which were not assembled here.
