Context

In August 2024, a team from the Innovation Laboratory of Chile's Judiciary (Corporación Administrativa del Poder Judicial) won OpenAI's first Latin America hackathon — the only public-sector team among 33 competitors — with 'Justa' (Justicia Ágil, Transparente y Automatizada), a generative-AI tool built on OpenAI models.

Objectives

Automate hearing transcription and minute-generation, and, for uncontested or mutual-consent family cases such as divorces, check submitted documents against legal requirements and draft a proposed sentence for a judge's review.

Activities

Justa was piloted first at the Juzgado de Letras y Garantía de Mulchén (Biobío Region) from December 2024, then expanded to the Juzgado de Familia de Antofagasta around April 2025. A related pilot at the Corte de Apelaciones de Temuco, with Universidad de La Frontera, automated case-comparison certifications required under Article 66 of Chile's Código Orgánico de Tribunales.

Results

The Judiciary's own figures report hearing transcription falling to 2-3 minutes per hearing, and the Temuco Article 66 certifications dropping from around 30 minutes per case to a few minutes.

Conclusions

These figures come from Poder Judicial press releases rather than an independent audit; trade-press coverage (LemonTech, Diario Financiero) has largely restated the official account rather than verified it independently. National rollout beyond the pilot courts is described as pending review by the Judiciary's Consejo Superior.

Implementation
Indicative cost
Low (< €50k) — Built in-house by the Judiciary's own Innovation Laboratory using existing OpenAI models after winning a hackathon; no separate procurement budget disclosed.
Time to results
Short (< 1 year) — Hackathon win in Aug 2024; piloted at Mulchén from Dec 2024, expanded to Antofagasta around Apr 2025 plus a related Temuco pilot; national rollout is pending Consejo Superior review.
Staffing & skills
Judiciary's Innovation Laboratory / Departamento de Desarrollo Institucional (Corporación Administrativa del Poder Judicial), pilot courts: Juzgado de Letras y Garantía de Mulchén, Juzgado de Familia de Antofagasta, Corte de Apelaciones de Temuco, academic partner: Universidad de La Frontera (Temuco Article 66 pilot)

Conditions for success

  • access to OpenAI models via an in-house build originating from a hackathon win
  • judge review retained for AI-drafted rulings (human-in-the-loop)
  • a governance gate (Consejo Superior review) before national rollout

Common failure modes

  • efficiency figures are self-reported by the Judiciary with no independent audit found
  • national scaling remains explicitly pending

Where it fits

Governance type
national judiciary / public-sector court administration
