Use of AI in Commercial Trials (Código de Comercio (Commercial Code), arts. 1055 Ter to 1055 Sexies)

What it is. Adds Chapter I Bis to Book Five 'On Commercial Trials' of the Código de Comercio (Commercial Code) to regulate the use of AI tools in commercial trials.

Who. Sen. Agustín Dorantes Lámbarri (PAN). When. Presented before the Comisión Permanente (Standing Committee) on July 8, 2026. Status. Referred to the Joint Commissions on Justice; Analysis, Monitoring and Evaluation on Artificial Intelligence in Mexico; and Legislative Studies, Second.

The Principles It Imposes

Subjects the use of AI tools to ten guiding principles: legality, transparency, traceability, human supervision, explainability, protection of personal data, non-discrimination, accountability, proportionality, and information security. Responsibility for actions and resolutions remains with judges and public officials with jurisdictional functions (jueces y servidores públicos con funciones jurisdiccionales): AI cannot substitute for legal reasoning, evaluate evidence automatically, determine disputed facts, or adopt decisions without human intervention.

Why It Matters

It is one of the 14 mirror initiatives that Senator Dorantes presented on July 8, 2026 to insert the same chapter, "On the use of AI tools," across nearly all Mexican procedural law—from administrative litigation (contencioso administrativo) and labor law to criminal, commercial, agrarian, and military law—plus a reform to Constitutional Article 17. Together they pursue a single standard: AI as an auxiliary tool, under human supervision and without substituting the judgment of those who judge or decide.
