Council of Magistracy of the Nation
The Council of Magistracy of the Nation (Spanish: Consejo de la Magistratura de la Nación) serves as a critical organ within the Judicial Branch of the Argentine government. Its primary purpose is to manage the lifecycle of the judiciary, ensuring a structured process for the selection and accountability of judges.
The Council holds significant authority over the federal judiciary, specifically regarding the appointment of judges. Beyond selection, it is responsible for presenting formal charges against judges to an Accusation Jury and possesses the power to suspend or depose judicial officers when necessary.

Key Facts
- Established: Created in 2002 via Law 25669 of the Argentine National Congress.
- Primary Role: Appointing, charging, suspending, and deposing judges.
- Evolution: Membership was reduced from 20 to 13 members during a 2006 reform.
- Composition: Includes representatives from the legislature, judiciary, legal profession, academia, and the executive branch.
Founding and Original Structure
When the Council was first established in 2002, it was designed as a broad representative body consisting of 20 members. This diversity was intended to balance the influence of different sectors of society and government.
The original 20-member composition included:
- The president of the Supreme Court of Justice.
- Four national judges, selected using the D'Hondt method (a mathematical formula used to allocate seats in proportional representation systems).
- Eight legislators, split equally between four Deputies and four Senators. These were distributed based on party strength: two for the majority party, one for the first minority, and one for the second minority.
- Four lawyers holding federal licenses, elected by their peers.
- One representative appointed by the Executive Branch.
- Two representatives from the scientific and academic fields, elected by their peers.
The 2006 Reform and Controversy
In 2006, the Council underwent a significant structural reform that reduced the total membership from 20 to 13. This change altered the balance of power within the organ, removing the representative of the Supreme Court and adjusting the quotas for other sectors.
Revised Membership (Post-2006)
The reformed Council consisted of:
- Six legislators.
- Three judges.
- Two lawyers.
- One academic.
- One representative of the Executive Branch.
This reform faced substantial opposition. Critics argued that the reduction transformed the Council into a more politically partisan body. At the time of the reform, the Justicialist Party—which held the majority in both houses of Congress—effectively controlled five seats: four through the legislative quota and one through the Executive Branch representative.
