What You Need to Know About the Decree Published on June 2, 2026

In the context of the 2024 Judicial Reform, on June 2, 2026, the evening edition of Mexico’s Official Gazette (DOF) published the Decree amending and supplementing various provisions of the Political Constitution of the United Mexican States concerning Judicial Reform. This reform modifies several aspects of Mexico’s legal and constitutional framework, in harmony with the 2024 reform that fundamentally transformed the Judicial Branch of the Mexican State.

This publication modifies key provisions at both the federal and local levels and adjusts the timelines for the transition toward the election of judges, magistrates, and justices by popular vote.

Below, we break down the most important points you should know about this decree:

1. Amendment to the Date of the Judicial Election (Art. 35)

The constitutional text was amended so that Judicial Branch elections will be held on the first Sunday of June in the fourth year of the constitutional term. The transitional provisions clarify that the next elections will take place on the first Sunday of June 2028.

2. New Structure of the Supreme Court of Justice of the Nation (Art. 94)

The reform structurally changes the operation of the Supreme Court of Justice of the Nation (SCJN). The Court will operate in Plenary Session, but it may also be divided and function through two sections, subject to the approval and determination of the Plenary itself. The presidency of the Court will no longer be held for fixed terms; instead, it will rotate every two years, with the position assigned to the justice who obtained the highest number of votes in the corresponding judicial election.

3. A New Screening Mechanism for Candidates: Evaluation Committees and Coordinating Commission (Art. 96)

To ensure that candidates possess the technical knowledge and suitability required to hold a judicial office, a more detailed selection process has been established:

• Evaluation Committees: Each of the three Branches of the Union (Executive, Legislative, and Judicial) will establish a committee composed of five individuals recognized for their experience and standing in judicial activities.
• Coordinating Commission: The coordinators of these three committees will form a commission responsible for standardizing knowledge examinations, evaluation criteria, and assessment methodologies.

The committees will prepare a list of the four highest-rated candidates for each position and, through a public lottery process, will reduce the list to only two candidates per position, while ensuring gender parity at all times.

4. Nomination and Election by Popular Vote (Arts. 35 and 96)

Once the Coordinating Commission’s screening process has been completed, each Branch of the Union will officially nominate two candidates for each position. The Executive Branch will do so through the Presidency; the Legislative Branch will require a qualified majority (two-thirds) in each chamber; and the Judicial Branch will do so through a majority of six votes from the Plenary of the Supreme Court of Justice of the Nation (SCJN). The National Electoral Institute will organize the elections by dividing the judicial circuits into districts to facilitate citizen participation in the voting process.

5. Permanent Vacancies (Art. 98)

If a Justice of the Supreme Court, a Magistrate of the Judicial Discipline Tribunal, or a Magistrate of the Electoral Tribunal dies, resigns, or permanently leaves office, the vacancy will be filled directly by the candidate of the same gender who obtained the second-highest number of votes in the election for that position. The Senate will be responsible for administering the oath of office for the remainder of the term.

6. Harmonization in the Federal Entities and Mexico City (Arts. 116 and 122)

La reforma no es exclusiva de la Federación. Los Poderes Judiciales Locales de los estados y de la Ciudad de México deberán sujetarse a las mismas bases establecidas a nivel federal.

7. Particularidades en Materia de Justicia Electoral

Los Magistrados del Tribunal Electoral del Poder Judicial de la Federación que se encuentran activos en la actualidad permanecerán en sus encargos hasta el 2028 para alinearse al nuevo calendario electoral, pudiendo ser reelegibles para dichas elecciones.

8. Plazos legislativos

El Congreso de la Unión tiene 90 días naturales para realizar las adecuaciones a las leyes secundarias. Las entidades federativas cuentan con 60 días naturales para adecuar sus constituciones locales y 90 días para sus leyes locales.

Conclusión

Este decreto del 2026 marca el inicio de una serie de adecuaciones a la reforma al poder judicial del 2024, ajustando cuestiones clave para asegurar que se lleve a cabo de manera efectiva el próximo proceso electoral. Con la mirada puesta en las elecciones judiciales masivas del año 2028 y la adición de dos secciones a la SCJN, los reflectores se colocan ahora sobre los Comités de Evaluación que definirán a los aspirantes que aparecerán en las boletas.
