Background and Relevance of the New Supreme Court Justices

Following the first judicial elections held on June 1, 2025, the newly elected members of Mexico’s Supreme Court of Justice of the Nation (SCJN), along with federal magistrates and judges, are set to take their oaths in a solemn ceremony on September 1, 2025. This event marks the formal beginning of their functions in the newly transformed judicial power.

The Judicial Reform and Its Impact

These elections, part of the September 2024 judicial reform, allowed for popular election of judges, magistrates, and ministers for the first time. The reform significantly changed the system by introducing direct popular voting, which has sparked debate.

  • Criticism: The use of “acordeones” (a type of electoral strategy) by Morena was criticized, with opposition parties warning about potential impacts on judicial independence.

Symbolic Changes in the SCJN

Hugo Aguilar Ortiz, a mixteco lawyer, was elected with high votes to preside the SCJN. His selection, alongside eight other official magistrates aligned with his views, signifies a shift in the judicial power.
