Overview

• The Senate approved the amparo reform after a contentious overnight session, passing it 76–39 in general and 70–39 in particular.
• The package modernizes procedures with digital filing, extends the deadline for indirect amparo rulings from 60 to 90 days, and revises the definition of legitimate interest to include collective claims.
• A transitory added by Morena Senator Manuel Huerta applies the new rules to cases already in process, effectively making the changes retroactive.
• President Claudia Sheinbaum said the retroactivity was not in her initiative and argued the Constitution forbids it, tasking Legal Counsel Ernestina Godoy with reviewing the clause as the bill moves to the Chamber of Deputies.
• Opposition parties branded the plan the “Ley del Desamparo” and signaled constitutional challenges, warning that tighter limits on suspensions—such as in frozen-account and fiscal cases—could curb access to remedies.
