In Mexico, the institutional framework of the judiciary consists of various components that make up the formal court system. The interaction between the formal court system and traditional justice mechanisms, particularly within indigenous communities, is a complex and evolving process.

The formal court system in Mexico includes federal and state courts. At the federal level, the highest judicial authority is the Supreme Court of Justice of the Nation (Suprema Corte de Justicia de la Nación, SCJN), Mexico’s constitutional court. It is responsible for interpreting the Constitution, resolving constitutional controversies, and ensuring that laws and acts of public authorities comply with constitutional and human rights standards. Following the 2024 judicial reform, the Supreme Court is composed of nine Justices (Ministras y Ministros) and operates exclusively in plenary session. Its current composition took office on 1 September 2025, following the 2025 federal judicial election. Below the Supreme Court, the federal judiciary includes Circuit Courts (Tribunales de Circuito) and District Courts (Juzgados de Distrito), which hear cases involving federal law and constitutional matters.

At the state level, each state has its own judicial structure. State supreme courts (Tribunales Superiores de Justicia) oversee the administration of justice within their respective states. Below the state supreme courts, there are appellate courts (Tribunales de Apelación) and trial courts (Juzgados de Primera Instancia) that handle state law cases.

Regarding the interaction with traditional justice mechanisms, Mexico recognizes the rights of indigenous peoples and their customary legal systems. The Mexican legal framework, particularly the Constitution and international human rights instruments, acknowledges the importance of indigenous justice and the right of indigenous communities to use their traditional dispute resolution mechanisms.

In practice, the interaction between the formal court system and traditional justice mechanisms can vary depending on the specific circumstances and the community involved. In some cases, there are mechanisms for collaboration and coordination between the formal courts and traditional authorities, aimed at respecting indigenous rights and ensuring access to justice. This may involve referrals of cases between the two systems, dialogue, and mutual recognition of decisions.

However, challenges exist in harmonizing the two systems, such as differences in legal procedures, language barriers, cultural sensitivity, and ensuring the protection of individual rights within traditional justice mechanisms. Efforts are ongoing to strengthen the dialogue and cooperation between the formal court system and traditional justice mechanisms, aiming to strike a balance between respecting indigenous autonomy and ensuring access to justice for all individuals.
