Mexico’s First-Ever Judicial Elections: Overview and Voter Turnout

On Sunday, Mexicans went to the polls to vote in the country’s first-ever judicial elections. Nearly 13 million people voted in the 2025 judicial election in Mexico, constituting just 13% of the country’s voting-eligible population. This marks the lowest voter turnout in an election in the past 30 years. While supporters of the judicial elections argued that low turnout in non-presidential contests was to be expected, the actual level of voter participation was quite low, though within the National Electoral Institute’s (INE) turnout estimates, which ranged from 8 to 20%. Of the 116.6 million votes cast, only 77% were valid votes. 12.6 million ballots (10.8%) were annulled votes, and another 14 million ballots (12%) were left blank. According to El Economista, the number of annulled votes in this election surpassed the previous record of 5.4% annulled votes in the 2009 midterm election.

Partisan Influence Despite Non-Partisan Rules

Though the elections were ostensibly non-partisan, with candidates barred from receiving endorsements from current politicians and/or political parties, partisan interference certainly played a role in the election outcome. As of today, June 4^th, the INE has received 29 election violation complaints accusing both Morena (the current ruling party) and Movimiento Ciudadano (MC) of distributing “acordeones” – physical and digital guides directing voters how to vote for candidates supported by each party.¹ The site for Morena, called Poder Judicial 4T (Judicial Power 4^th Transformation), can be found here. The site is comprehensive, listing each of Mexico’s 32 federal entities. On each of the 32 state-specific site pages are examples of the ballots with the preferred candidates selected. It’s worth noting that days before the election, the INE explicitly prohibited the use of acordeones. It’s also worth noting that all nine candidates listed on Morena’s acordeón won seats on the Supreme Court.

Who are the newly elected Supreme Court justices?

With 91.7% of the votes counted, the nine candidates who received the greatest vote share for the position of Supreme Court Justice have been identified. The election results will be certified on June 15. Of the nine seats, five are legally required to be held by women and four by men. Of the nine judges, five are closely affiliated with Morena in some capacity. Three of the newly elected Supreme Court justices are currently serving on the Supreme Court and were initially appointed by AMLO during his presidency. One judge previously served as a legal advisor to AMLO, while another worked as a congressional advisor to Morena.

Hugo Aguilar Ortiz

6.19 million votes (5.3%)²

A Mixtec lawyer from the state of Oaxaca, Hector Aguilar Ortiz secured the greatest number of votes in the election, thus making him the Chief Justice of the Supreme Court. Aguilar has dedicated his career to the legal defense of indigenous affairs.

He previously represented the Zapatista National Liberation Army during the San Andrés Larraízar peace talks in Chiapas in 1996. Throughout his career, Aguilar has held various roles in public service defending Mexico’s indigenous communities, including serving as the Undersecretary of Indigenous Rights in the Secretariat of Indigenous Affairs of the Government of Oaxaca. He is only the second person of indigenous heritage to serve as chief justice of the Supreme Court, the other being the former president of Mexico, Benito Juárez. Of note, Aguilar does not have any prior experience as a judge. He is not explicitly affiliated with Morena, but joined the federal government during AMLO’s term. He worked with the AMLO administration on various consultation projects, including the Tren Maya and the Felipe Ángeles International Airport.

Lenia Batres Guardarrama

5.8 million votes (4.97%)

Lenia Batres Guardarrama is currently a judge on Mexico’s Supreme Court, directly appointed by AMLO in 2023 after the Senate failed to confirm any of his three nominees. This direct appointment was unprecedented and raised significant concerns about the politicization of Mexico’s highest court.

Originally from Mexico City, Batres’ career spans 35 years. An attorney by training, Batres’ public service career began in 1988 when she joined INEGI. For the next decade, she worked as a journalist and eventually became an advisor to the Chamber of Deputies in 1994. She was elected as a federal deputy, representing the Partido de la Revolución Democrática (PRD, the forerunner to Morena), in 1997. She served in the local Federal District government in the early 2000s, eventually becoming the advisor to AMLO when he served as the Head of Government of the Federal District.

Batres served as an advisor to Claudia Sheinbaum from 2015 to 2018 when the latter served as Mayor of Tlalpan. She continued her work with Sheinbaum during her term as Head of Government of Mexico City, working as a legal advisor to the Secretariat of Urban Development and Housing. She left this role in 2021 to serve on the legal counsel team of then-president AMLO. Batres has been a member of Morena since the party’s inception in 2014, and her family maintains close ties to the party. Her brother, Martí Batres, currently serves as the Sheinbaum administration’s head of the ISSSTE (Institute for Social Security and Services for State Workers).

Esquivel is known for her efforts to modernize Mexico’s judicial system, specifically through gender parity. However, she was at the center of controversy in 2022 after a journalistic investigation into her undergraduate thesis revealed “high levels of similarities” between her thesis, written in 1987, and another thesis published the year prior. A civil court determined that she was the legitimate author of the thesis. While Esquivel’s party affiliation is not explicitly listed, she is a close ally of Morena, and has cast votes in favor of several key reforms during the AMLO administration, including the including the constitutionality of the electoral reform, known as “Plan B”, and changes to Mexico’s Electric Industry Law – both of which were ultimately deemed unconstitutional by the Supreme Court.

She worked closely with the AMLO administration on various pacification projects around the country, and in 2018, AMLO mentioned Ortiz as a potential candidate for the Supreme Court. As such, Ortiz left Morena that same year, citing impartiality, and remains politically unaffiliated. In 2021, she was named to the court and played a key role in supporting reforms proposed by AMLO, including the electoral reform and changes to the Electricity Industry Law.

President Sheinbaum’s Comments on the Election Results

Unsurprisingly, President Sheinbaum’s comments about the judicial elections have been resoundingly positive, regardless of the low voter turnout. Throughout her mañaneras this week, Sheinbaum has consistently underscored the success of the elections and went so far as to characterize Mexico as the “most democratic country in the world.” She highlighted that voter turnout for the judicial elections (13 million) was greater than the number of individuals who voted for the PRI (5.7 million) and the PAN (9.6 million) in the 2024 presidential election in an attempt to discredit claims of election illegitimacy due to low voter turnout. In the face of threats of protest against the election, the head of the INE, Guadalupe Taddei, has affirmed the constitutionality of the elections, stating that there would be no constitutional crisis.

Why Mexico’s Judicial Elections Matter: Implications for Mexico and the US-Mexico Relationship

Exactly one year and one day after the historic election of Claudia Sheinbaum, Morena made history again as the only political party to control all three branches of Mexico’s government. Though no longer in office, AMLO’s specter shines bright and will continue to shine as the newly appointed court adjudicates reforms that trace their roots back to the former president. Ironically, AMLO has remained largely out of the public eye since leaving office last year, only emerging on Sunday to vote in the judicial elections. And yet, AMLO’s presence in Mexican politics remains outsized, embodied in these consequential elections that will define his legacy. Maybe even more enduring, however, are their implications for the future of democracy in Mexico.

These elections, but perhaps more importantly, Morena’s now-solidified control of the judicial branch represents the crowning glory of the 4T movement, a long-sought-after achievement in further expanding and securing the party’s far-reaching and wide-ranging political control. While time will only tell how these justices will vote, if precedent teaches us anything, we can expect allegiance to the 4T and support for the reforms that the president and party put forth. AMLO made clear that loyalty to the 4th Transformation is rewarded with key positions of influence and authority. This election reaffirmed as much.

As for the US-Mexico relationship, the judicial elections present another layer of uncertainty in an already volatile landscape, heightened by rapidly evolving policy decisions on the US side, particularly in terms of trade. The Trump administration’s unpredictable and unwieldy use of trade policy to non-trade-related issues has already caused significant challenges in the investment landscape as companies struggle to plan accordingly, with tariffs seemingly changing on a month-to-month basis. Now, Mexico is adding to the uncertainty of the investment climate with companies reconsidering investments in Mexico amid concerns over whether they will receive impartial treatment in the face of legal disputes.
