Overview

• By unanimous vote, the Court upheld INAI’s June 8, 2022 order and instructed the Presidency to deliver 15 Semar oficios—11 on appointments and adscriptions of admirals and vice admirals, and four on training and multinational exercises.
• The justices ruled that the national‑security argument, including the mosaic theory, was unpersuasive in this case because the contested data are already in the public domain.
• The ruling requires the responsible official to verify and redact any details not yet public before disclosure to mitigate potential risks.
• Minister María Estela Ríos González was formally declared impeded from the case due to her prior role as the Presidency’s legal counsel who filed the appeal.
• As the reconstituted Court implements new committees to process cases after the 2024 reform, a separate set of FGR transparency disputes exposed a 6–3 split on releasing staff data, with the Court also upholding nondisclosure in another matter based on the mosaic methodology.
