Overview

• The Senate approved the package 76–39 in general and 70–39 in particular, modernizing amparo with digital filings, a 90‑day limit for indirect rulings, a broader concept of legitimate interest and tighter suspensions in fiscal and UIF account‑freeze matters.
• A reserved first transitory, promoted by Morena senator Manuel Huerta Ladrón de Guevara, states that cases already in progress would continue under the new rules once the decree takes effect.
• President Claudia Sheinbaum publicly disavowed that transitory, stressing the Constitution bars harmful retroactivity and noting her original initiative did not include such a provision.
• The Senate’s minuta was sent to the Chamber of Deputies, where leadership has promised extensive debate, hundreds of reservations and commission review of the contested clause before any final vote.
• Opposition parties and legal collectives condemned the reform as curbing protections, signaled plans to challenge contentious provisions before the Supreme Court and warned the retroactivity language could be unconstitutional.
