Day 610 — Three Judicial and Electoral Reforms Enter Into Force: Judicial Election Postponed to 2028, 'Ley Monreal' Now Law

On June 3, 2026 (Day 610), the three electoral and judicial reform decrees published in the Diario Oficial de la Federación on June 2 officially entered into force. Key changes now in effect: (1) JUDICIAL ELECTION TIMELINE: The next round of judicial elections — covering the remaining 2,681 federal judicial posts — is formally postponed from June 2027 to June 4, 2028. The postponement avoids calendar conflict with 18 gubernatorial elections and creates additional time for the new INE integrity commission to develop vetting standards. (2) 'LEY MONREAL': Foreign interference in Mexican electoral processes is now formally sanctioned as a ground for electoral nullity, with criminal penalties for foreign nationals and entities. Senate leader Ricardo Monreal presented the reform as 'a legal shield for Mexico's sovereignty.' The law is part of the broader sovereignty narrative Sheinbaum advanced in her May 31 Second Government Report and the confrontation with U.S. Ambassador Johnson. (3) INE INTEGRITY COMMISSION: A new commission within the National Electoral Institute began operating, with jurisdiction to pre-screen judicial candidates for disqualifying conflicts of interest. Opposition parties — PAN, PRI, Movimiento Ciudadano — challenged the decrees as unconstitutional, arguing the judicial election postponement effectively alters the constitution without following proper amendment procedures. Legal challenges were filed before the newly constituted Supreme Court.
