Overview

• The Senate approved the Ley de Amparo overhaul 76–39 and, as of Friday evening, had not yet delivered the minute to the Chamber of Deputies, the lower house president said.
• Supreme Court President Hugo Aguilar Ortiz called the streamlining reform necessary but said the retroactivity provision must be adjusted and signaled the Court would correct it if Congress leaves it intact.
• President Claudia Sheinbaum urged deputies to strike the retroactive transitory clause, citing the Constitution’s prohibition on laws that harm persons retroactively.
• Business leaders from Concamin, CCE and Coparmex warned the changes—particularly retroactivity and tighter suspension rules—threaten legal certainty, investment and jobs, and pressed deputies to revise the bill.
• The package promotes online amparo proceedings, clarifies individual and collective legitimate interest, tightens suspensions in fiscal cases, and preserves sanctions for officials who defy rulings; controversy stems from a transitory clause adopted by economic vote to apply the new rules to cases in progress.
