Overview

• Lawmakers approved the package 76–39 after late‑night debate, covering the Amparo Law, the Federal Fiscal Code and the Organic Law of the Federal Administrative Justice Tribunal.
• Key edits define legitimate interest as individual or collective and remove the requirement that the harm be “actual,” aiming to preserve access for collective and diffuse claims.
• A 90‑day deadline for issuing amparo judgments replaces a shorter proposal, and digital procedures expand with the option to proceed traditionally.
• The reform restricts suspensions in sensitive areas, including actions tied to money‑laundering and terrorism financing, UIF account freezes, activities lacking federal concessions or authorizations, and public debt matters.
• Fiscal changes seek to prevent reopening litigation over firm tax credits and curb dilatory challenges, while opposition parties denounce a rights rollback and warn about a disputed transitory clause alleged to enable retroactivity.
