Overview

• The Senate approved an Amparo reform with a transitory granting retroactive effect to cases already in progress and sent the bill to the Chamber of Deputies.
• President Claudia Sheinbaum said her initiative did not include the clause and stressed that the Constitution prohibits harmful retroactivity, with her legal counsel set to review the text.
• Senate commission leaders Enrique Inzunza and Javier Corral opposed the reserve, left the floor, and called the retroactive provision absolutely unconstitutional.
• Morena senator Manuel Huerta reintroduced the transitory after midnight and argued that Supreme Court theses allow such application when acquired rights are not affected.
• Opposition lawmakers, legal scholars, and business groups warned of risks to due process and collective remedies as the package also accelerates rulings and restricts certain suspensions, including in money‑laundering and Supreme Court contexts.
