Rows highlighted FSP mark presidents from a Foro de São Paulo member/affiliated party.
| Period | President | Party | Notes |
|---|---|---|---|
| 1989–1999 | Carlos Menem | PJ | Peronist, pre-Kirchner. |
| 1999–2001 | Fernando de la Rúa | UCR/Alianza | Resigned in the 2001 crisis. |
| 2002–2003 | Eduardo Duhalde | PJ | Appointed by Congress after interim presidents. |
| 2003–2007 | Néstor Kirchner FSP | PJ/FpV | |
| 2007–2015 | Cristina Fernández de Kirchner FSP | FpV | |
| 2015–2019 | Mauricio Macri | PRO/Cambiemos | |

High court — Corte Suprema de Justicia de la Nación
- Seats
- 5
- Appointment
- Nominated by the President, confirmed by 2/3 of the Senate.
- Appointed under FSP-party govts
- 1 of 3 sitting justices — a minority of the current bench. This is appointment provenance (who nominated each justice), not a claim about how they rule — justices serve independently.
- Changes (FSP era)
- In 1990 President Menem (Peronist, pre-Kirchner) expanded the court from 5 to 9 (Law 23.774), creating an "automatic majority". In 2006 the Kirchnerist government reduced it back to 5 (Law 26.183) and had tightened the appointment process (Decree 222/03, 2003). So the packing predates the Kirchnerist (FSP-affiliated) governments, which actually de-packed it — a useful counter to a simplistic 'FSP packs courts' reading.
- How much remains
- After the retirements of Highton (2021) and Maqueda (2024), the court fell below its 5-seat complement to 3 justices; President Milei's attempts to fill the seats by decree (Lijo, García-Mansilla) failed in the Senate (2025), leaving a deadlock as of 2026.

Court history (1990–present)
Structural changes to the court during the Foro de São Paulo era — size changes, court-packings, purges and reforms. packing/purge mark expansions and forced removals. Sources: source · source.
| Period | Type | Change | Seats | Government |
|---|---|---|---|---|
| Before 1990 (context) | composition | Earlier history: the Corte Suprema was installed in 1863 (5 justices). In 1947 Perón's Congress removed 4 of the 5 justices; the court was expanded 5→7 (1958) and returned to 5 (1966); the 1976–83 junta replaced it. Reshaping the court by incoming governments was a long-running pattern before 1990. | 5 | various (1863–1989) |
| 1990 | packing | Law 23.774 (Menem) expanded the court from 5 to 9, creating the 'automatic majority'. | 9 | Carlos Menem (PJ) |
| 2003 | reform | Decree 222/03 (Néstor Kirchner) opened Supreme Court nominations to public scrutiny, applied to the post-Menem vacancies. | 9 | Néstor Kirchner (FpV) |
| 2006 | reform | Law 26.183 (promoted by Cristina Fernández de Kirchner) reduced the court from 9 back to 5, reversing Menem's expansion. | 5 | Kirchnerist government (FpV) |
| 2024–present | composition | After Highton (2021) and Maqueda (2024) left, the court fell to 3 justices; Milei's decree appointments (Lijo, García-Mansilla) were rejected by the Senate in 2025, leaving the seats vacant amid a deadlock. ? | 3 | Javier Milei (LLA) — contested |
Bench control by appointing government
Sourced period bands: how much of the sitting high-court bench was appointed (or, where sources say so, effectively controlled) under FSP-member governments. Appointment provenance is not a claim about how judges rule — see each band's notes; documented interventions are in the court history above. Seat counts appear only where sources give them; years outside these bands are uncovered, not asserted.
| Period | Control | FSP-era appointees | Notes & sources |
|---|---|---|---|
| 1990–2002 | independent | 0 of 9 | Menem's 1990 expansion to 9 seats and its 'automatic majority' predate any FSP-linked government; no Kirchner-era appointees sat on the court. (source 1, source 2) |
| 2003–2004 | partial | bench of 9 | Néstor Kirchner's renewal under the open Decree 222/03 process seated Zaffaroni (2003), then Highton and Lorenzetti (2004), as Menem-era justices resigned or were impeached — 1 to 3 of the 9 seats. (source 1, source 2) |
| 2005–2014 | aligned | 4 | Four of the seven sitting justices (Zaffaroni, Highton, Lorenzetti, and Argibay from Feb 2005) were Kirchner appointees — a majority of the sitting bench, while Law 26.183 (2006) shrank the statutory size from 9 toward 5 by attrition. The ICJ described the openly-vetted renewal as strengthening independence, and the court repeatedly ruled against the government — notably striking down the 2013 judicial-council reform. (source 1, source 2, source 3) |
| 2015–present | partial | bench of 5 | After the 2014–15 departures of Petracchi, Argibay, Zaffaroni and Fayt, Kirchner-era appointees fell to 2 of 5 (Lorenzetti, Highton) beside Macri's 2016 appointees (Rosatti, Rosenkrantz); with Highton's exit (2021) and Maqueda's (2024), 1 of the 3 sitting justices (Lorenzetti) as the Senate rejected Milei's 2025 nominees.
