Ley General de Transparencia y Acceso a la Información Pública
LGTAIP (DOF 4-5-2015)
Mexico's general transparency law, filed through the Plataforma Nacional de Transparencia. INAI, the independent oversight body, was dissolved in 2025 and its functions moved into the federal executive.
The clock
20 business days
20 días hábiles, extendable by 10 with cause.
SEDENA answers in Spanish and leans on the seguridad-nacional reserve for operational detail.
Reading the statute itself
The text of this one is not reproduced here: foreign legislation is published under its own country’s copyright rules, so it is linked instead. Everything on this page — the deadline, the appeal path, the fee standard — is Aletheca’s summary of that text, and the official source is one click away.
If they refuse
- Appeal deadline
- 15 days — días hábiles to file a recurso de revisión
- Appeal route
- Recurso de revisión within 15 business days — heard since 2025 by Transparencia para el Pueblo, under the anti-corruption secretariat, after INAI's dissolution.
- Litigation
- Juicio de amparo before the federal courts.
Fees and expedition
Fee-waiver standard
Free; reproduction and delivery at cost.
Aletheca argues this on every request it files here. A service that publishes every page it receives, free, to a public archive has an unusually strong showing — considerably stronger than a private requester’s.
Exemptions it allows
- Seguridad nacional
- Información reservada (up to 5 years, renewable)
- Datos personales
Quirks worth knowing
The independent appeals body no longer exists; the review now sits inside the executive branch it reviews, which should temper appeal expectations.
