Mexico’s Contentious Judiciary Overhaul Becomes Law

Mexico’s sweeping judicial overhaul became part of the constitution on September 15, 2024, after President Andrés Manuel López Obrador signed and published the decree. The reform replaced appointments with popular elections for judges at every federal level, including the Supreme Court, and triggered an unprecedented institutional transition.

Congress approved a constitutional amendment

Morena and allied parties passed the proposal through the Chamber of Deputies and secured the required two-thirds Senate majority. More than half of state legislatures then ratified it, satisfying Mexico’s amendment process.

Protests and a judicial-workers’ strike accompanied the rapid legislative debate.

Voters would choose federal judges

The new system scheduled elections for Supreme Court justices, electoral judges, circuit magistrates and district judges. A first vote in 2025 would fill the Supreme Court and other posts, with remaining positions following in 2027.

Candidate screening involved nominations by the executive, legislature and judiciary.

The Supreme Court was reduced

The number of justices fell from 11 to nine and terms shortened from 15 years to 12. The presidency of the court would follow the new electoral arrangement rather than the previous internal convention.

Sitting judges faced elections or departure under transitional provisions.

Governance bodies were replaced

The Federal Judiciary Council was divided into a judicial administration body and a new discipline tribunal. Supporters said the structure would improve accountability.

Critics warned that a powerful disciplinary institution could pressure judges if its independence was weak.

López Obrador argued corruption demanded change

The outgoing president said courts were remote from ordinary citizens, protected privilege and sometimes released criminals improperly. Direct election, he argued, would give the public control and make justice more democratic.

Those diagnoses were politically powerful but did not establish that elections would correct each problem.

Opponents feared partisan capture

Judges, bar groups, opposition parties and international observers warned that candidates could depend on party structures, wealthy donors or criminal organizations. Popularity contests might also reward simple promises over legal competence.

Campaign finance, ballot design and vetting therefore became essential safeguards.

Markets and partners raised concerns

Investors depend on predictable enforcement of contracts, while the United States and Canada rely on Mexican courts under their trade relationship. Critics said sudden turnover could weaken expertise and confidence.

Mexico’s government rejected foreign criticism as interference in a sovereign decision.

Independence and accountability are both necessary

An appointed judiciary can suffer nepotism, delay and corruption; an elected one can suffer campaign influence and majoritarian pressure. Selection method alone does not guarantee impartial decisions.

Transparent qualifications, secure tenure, reasoned judgments and enforceable ethics matter under either model.

Implementation became the decisive test

Election authorities had to organize an enormous new ballot while legislators enacted secondary laws. Courts simultaneously continued ordinary cases despite uncertainty over personnel.

The decree legally settled that the system would change, not whether it would improve justice. That judgment required tracking candidate quality, participation, case delays, disciplinary practice and decisions involving the government. Responsible coverage should present the reform’s democratic promise and independence risks without assuming either outcome in advance.

Mexico’s first judicial ballots would provide evidence, but institutional effects would take years to assess.
