Mexico is entering uncharted territory this week as its first elected Supreme Court is officially seated in Mexico City. This new chapter for the nation’s highest judicial body is set to begin on Monday, September 1, 2025, and all eyes—both domestic and international—are watching to see whether the court will chart an independent course or fall under the sway of the governing party that engineered the country’s inaugural judicial elections.
The historic shake-up comes after sweeping reforms initiated by former President Andrés Manuel López Obrador, who argued that electing judges would make them more accountable to the public and less susceptible to corruption. According to the Associated Press, López Obrador’s vision was that judges “elected by the people would be more accountable and less corrupt.” But critics weren’t convinced, warning that the move could further politicize the judiciary and undermine its independence.
The numbers alone were staggering. More than 7,700 candidates vied for over 2,600 judicial positions nationwide, and the process was anything but simple. Many voters, faced with a dizzying array of names and affiliations, found themselves overwhelmed. Despite the election’s official nonpartisan status, reports surfaced of voting pamphlets linking certain candidates to Morena—the governing party, which now also holds majorities in both chambers of Congress. This raised concerns about the true independence of the process, even before the new justices took their seats.
Among the nine members of the new Supreme Court, only three have prior experience on the high court. The rest, including the court’s new president, Hugo Aguilar, are newcomers. Aguilar, a lawyer renowned for his work defending Indigenous rights, now faces the daunting task of steering a court that must quickly prove its impartiality.
“If the court wants to ensure its independence, it cannot rule in a partisan manner simply to support the government’s position,” said Juanita Goebertus, Americas director for Human Rights Watch, as quoted by the Associated Press. “It must base its positions on law.”
The stakes are high. The court inherits a docket brimming with nearly 1,400 pending cases, many of which touch on issues at the heart of Mexico’s social and political fabric. Among the most pressing is the controversial policy of automatic pretrial detention, which was expanded under López Obrador’s administration. While the government argues that this measure is essential for combating criminal activity and protecting judges, critics and international observers say it flagrantly violates human rights treaties to which Mexico is a signatory.
The United Nations High Commissioner for Human Rights and the Inter-American Court on Human Rights have both called for Mexico to repeal the policy. The numbers are sobering: as of 2023, four out of every ten people in Mexican prisons had not been convicted of a crime, according to the Federal and State Penitentiary Systems census. In a country where legal proceedings can drag on for years without resolution, and only one in five of those charged are ultimately convicted, the policy’s human toll is impossible to ignore.
Yet, the previous Supreme Court sidestepped the issue in its final days, leaving the new justices to tackle one of the most contentious and closely watched questions facing the Mexican legal system today.
Another area where the new court’s independence will be tested is reproductive rights. The previous court made history in 2021 and 2023 by expanding access to abortion, ruling that federal criminal penalties were unconstitutional and violated women’s human rights. However, under Mexico’s complex legal system, the 2023 ruling did not automatically invalidate state-level statutes—meaning that abortion remains criminalized in many states. The new court is expected to face challenges from states that have yet to update their penal codes, and there is widespread uncertainty about whether the justices will maintain the progressive legal reasoning of their predecessors.
“Uncertainty will prevail about whether the new court will preserve the same line of legal reasoning of recent years on the issue until the justices take up the cases,” explained Ana Cárdenas, director of justice projects in Mexico for the World Justice Project, in comments reported by the Associated Press.
Transgender rights are also poised to come before the court again. Previous justices handed down landmark decisions allowing transgender individuals to change the gender on their birth certificates through a simple administrative procedure, eliminating the need to go before a judge. In 2022, the court extended this right to children. However, Human Rights Watch points out that only seven of Mexico’s 32 states currently allow children to modify their identity documents to reflect their self-perceived gender identity. The new court may soon be called upon to address this uneven legal landscape.
Meanwhile, economic and environmental issues are also in play. In 2023, the governing party pushed through significant changes to the country’s mining laws, cutting the maximum length of mining concessions from 50 to 30 years and allowing authorities to cancel concessions if no work is done within two years. This move was met with both applause and criticism. While some praised the effort to curb speculation and address ecological damage, others—especially in the mining industry, much of which is foreign-owned—warned of unintended consequences for investment and local economies. Communities near mines, which often remain among the poorest in Mexico, have also voiced concerns about the impact of these changes. Challenges to the new mining laws are among the cases awaiting the Supreme Court’s review.
All told, the new court is stepping into a role that is both powerful and fraught with risk. The sheer volume and complexity of the cases before it would be daunting in any context. But the added pressure of proving its independence—especially after an election process criticized for its opacity and apparent partisanship—raises the stakes even higher.
International observers, civil society groups, and legal experts will be watching closely as the court begins its work. The outcome could reverberate far beyond Mexico’s borders, shaping not only the country’s legal landscape but also its standing as a democracy committed to the rule of law.
For now, the justices face a simple but profound choice: to serve as a genuine check on political power, or to become another arm of the government they are meant to oversee. The coming months will reveal whether Mexico’s first elected Supreme Court can rise to the occasion—or whether the experiment in judicial democracy will fall short of its lofty goals.
