Overview

• The Senate approved changes to the Ley de Amparo with recorded votes of 76–39 in general and 70–39 in particular, moving the bill to the Chamber of Deputies.
• A last‑minute transitory from Senator Manuel Huerta would apply the reform to pending cases, drawing objections that it violates Article 14’s ban on retroactive laws.
• Morena floor leader in the lower house Ricardo Monreal signaled the controversial transitory could be corrected during the Chamber’s review.
• Core changes tighten the standard for legitimate interest to a real, current and differentiated injury, curb suspensions including against UIF account freezes, extend some judicial deadlines to 60–90 days and expand digital procedures.
• Opposition leaders announced a wave of amparos against the reform, business groups such as Coparmex and Canacintra warned of weaker protections and legal uncertainty, and former justice Margarita Ríos‑Farjat voiced concern as scholar Jaime Cárdenas defended the measure’s anti‑evasion goals.
