The Mexico pages rest on the 1917 Constitution (the Supreme Court's per-article texts and a current-text mirror), the official gazette for the 2024 judicial reform, the IACHR and the OAS for the contested assessments, and the World Prison Brief for the prison figures. Each was confirmed on 27 July 2026 and independently re-checked; the federalism articles and the reform texts were confirmed verbatim, and the World Prison Brief figures re-confirmed by hand.

The official gazette (Diario Oficial de la Federación) publication of the 2024 constitutional decree "en materia de reforma del Poder Judicial", read directly and re-confirmed. Cited, with its date, for the enacted facts of the judicial reform: judges of the Supreme Court, circuit magistrates and district judges are to be "elegidos de manera libre, directa y secreta por la ciudadanía" (Art. 96); the model is imposed on the state judiciaries, which must provide for election by direct citizen vote and create a Judicial Discipline Tribunal and a judicial-administration body (Art. 116-III); and the Supreme Court is reduced to nine Ministers with the Council of the Federal Judiciary replaced by the two new bodies (Art. 94). Recorded neutrally as enacted law with its date; assessments of the reform are attributed separately to the IACHR and the OAS observation mission.

The OAS Electoral Observation Mission's preliminary report on the June 2025 judicial elections (mission chaired by Heraldo Muñoz), confirmed in two passes. Cited, by attribution and with its date, that the Mission reported a turnout of about 13% ("one of the lowest turnout levels in the region"), described the process as "extremely complex" and "polarizing", and concluded that it does not recommend this model of judge selection be replicated in other countries in the region.

The World Prison Brief country page for Mexico (compiled by ICPR from the national prison administration), read directly and re-confirmed by hand on the day of authoring — its figures had updated since the research pass, so the current values are used. Supports a total prison population of 268,245 including pre-trial detainees at 31 May 2026 (source: the national prison administration); a rate of 197 per 100,000 (UN population estimate); an official capacity of 227,658 at the same date; and an occupancy level of 117.8% at 31 May 2026 — above capacity, population and capacity carrying the same date. The page names the administering body as the Órgano Administrativo Desconcentrado de Prevención y Readaptación Social; its "ministry responsible" label ("Comisión Nacional de Seguridad") is out of date (that body was dissolved in 2018).
