Overview

• Mexico’s Senate approved the Amparo Law reform with 76–39 in general and 70–39 in particular votes and sent the minuta to the Chamber of Deputies.
• Senator Manuel Rafael Huerta introduced a first transitory clause to apply the new rules to cases already in progress, triggering constitutional objections under Article 14.
• President Claudia Sheinbaum said her initiative did not include retroactivity and called the transitory unnecessary, urging adherence to the Constitution’s ban on harmful retroactive laws.
• House leader Ricardo Monreal said the clause is legally risky and pledged a careful review in the Justice Commission without a fast track, signaling potential edits to align with non‑retroactivity.
• The reform package modernizes amparo procedures with digital filings, adjusted decision deadlines, a refined concept of legitimate interest, and tighter limits on suspensions in cases like UIF account freezes, while business group COPARMEX warned of legal uncertainty and investment risks.
