Overview

• Deputies passed the reform in general by 345–131 with three abstentions and returned the amended minuta to the Senate after a marathon session.
• Lawmakers approved a reserve from Hugo Eric Flores 322–128 that applies the new law to procedural steps still pending in ongoing amparos, which supporters frame as immediate procedural application and opponents denounce as disguised retroactivity.
• Key changes tighten standing by elevating the threshold for legítimo interés, replace the “interés público” criterion with “disposiciones de orden público,” and establish a digital amparo process.
• Suspensions are narrowed, including limits in cases such as UIF-ordered account freezes and when parties seek to continue activities requiring federal permits or after revocation of permits, authorizations or concessions.
• The vote exposed ruling-bloc dissent, with abstentions by Olga Sánchez Cordero and others and a handful of allied votes against, as Fitch warned the overhaul could raise regulatory risk for permit‑dependent sectors like energy, transport, telecoms, mining and infrastructure.
