Justice and public safety in Argentina
Argentina is a federation with a distinctive division: the criminal code is national, but the courts, prosecution, police and prisons that apply it to ordinary crime are largely provincial. Its federal prosecution is a constitutionally autonomous "fourth branch", constitutional review is diffuse with no constitutional court, and the constitutional Ombudsman has stood vacant since 2009.

Argentina (the Argentine Republic) is a federation of 23 provinces and the Autonomous City of Buenos Aires, with a civil-law tradition and a United-States-style federal architecture. The provinces "keep all power not delegated by this Constitution to the federal Government" (Article 121), and each must guarantee its own administration of justice (Article 5). Judges hold office "during good behaviour" with irreducible compensation (Article 110).
At the federal level the Supreme Court of Justice of the Nation sits at the apex, the prosecution is a constitutionally autonomous body, and the four federal police forces and the federal prison service both sit under the Ministry of Security. Alongside them, each province runs its own justice system.
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 |
|---|---|---|---|---|
| Argentine Nation | federal | shared | shared | shared |
| Provincia de Buenos Aires | province | own | own | own |
| Córdoba | province | 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 Argentina: 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 Argentina (the federal and provincial forensic bodies, and the Argentine Forensic Anthropology Team) 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 Argentina involve the National Gendarmerie, the Naval Prefecture, the migration directorate and the customs agency, and could not be researched to the standard required here without risking an inaccurate description of a security-sensitive function.
- Institutional historyNot researched
- Argentina's institutional history — the 1853 Constitution and its 1994 reform, the adoption of diffuse constitutional review on the United-States model, and the ongoing shift to an accusatory federal criminal process — 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 — the 1853/1994 Constitution, the 2019 accusatory Federal Code of Criminal Procedure and its phased rollout, and the 2024 transfer of the Federal Penitentiary Service — are a start, but a responsible timeline needs primary sources for each milestone, which were not assembled here.

Constitution of the Argentine Nation (1853, reformed 1994)
Political Database of the Americas (Georgetown University) — official constitutional text · Legislation · 1853 · link verified 2026-07-27
The Constitution of the Argentine Nation (1853, comprehensively reformed 1994), confirmed verbatim in two independent passes. Supports Art. 5 (each province shall enact its own constitution and guarantee its own administration of justice); Art. 75 inc. 12 (Congress enacts the national codes — Civil, Commercial, Criminal, etc. — "without such codes altering the local jurisdictions", their application corresponding to the federal or provincial courts by subject-matter); Art. 108 (the judicial power of the Nation is exercised by a Supreme Court of Justice and inferior tribunals); Art. 110 (life tenure during good behaviour and irreducible compensation — judicial independence); Art. 114 (the Council of the Magistracy selects judges and administers the judiciary); Art. 120 (the Public Ministry is an independent organ with functional autonomy and financial self-governance — a fourth, extra-branch body); Art. 121 (the provinces keep all power not delegated to the federal Government — the reserved-powers clause); and Art. 86 (the Ombudsman, Defensor del Pueblo). Establishes the federation, the national codes applied by provincial courts, the autonomous Public Ministry, and the reserved-powers rule.
World Prison Brief — Argentina
Institute for Crime & Justice Policy Research (ICPR), Birkbeck, University of London · Academic · link verified 2026-07-27
The World Prison Brief country page for Argentina (compiled by ICPR from the Ministry of Justice SNEEP data), read directly and re-confirmed by hand. Supports a total prison population of 133,585 at 31 December 2024 — a figure that includes 12,885 people held in police lock-ups (comisarías) — a rate of 284 per 100,000, and an official capacity of 98,199 (not including police lock-ups) at the same date, giving an occupancy level of 122.9% for the prison system proper. Prisons are run at both the federal (Servicio Penitenciario Federal) and provincial levels, so this is a national aggregate; the occupancy compares the prison-system population and capacity, both excluding the police lock-ups that the total includes.
