CJF Sentencias

Mexico’s federal judiciary publishes public versions of its rulings. Search them by full text, with four match modes (exact phrase, at least one word, except a word, or a range of words apart) and optional date bounds, and pull any ruling’s record by its NEUN: issuing court, subject matter, topic and summary, and the record section by section.

These are public-version rulings (versiones públicas) of Mexico’s federal courts: personal data is redacted by the publisher before release.

These lookups can take longer than a typical request. They are async jobs. By default the request waits inline and returns { data }, or you can poll / use a callback_url.
