On March 4, 2023, Argentine President Javier Milei announced the appointment of Juan Bautista Mahiques as the new Minister of Justice, replacing Mariano Cúneo Libarona who formally resigned. The change is seen as significant as it alters the internal power dynamics within Milei's government. The decision was made public via a post on President Milei's official social media account after a meeting at the Quinta de Olivos, the presidential residence.

Juan Bautista Mahiques, before his current appointment, was the head of the Buenos Aires Public Prosecutor's Office and has strong connections to the national judiciary. He has previously served as the Executive Representative in the Council of Magistracy during Mauricio Macri's presidency, thus bringing a wealth of experience in legal and governmental affairs. His background is considered apt for the role, especially as the new administration seeks to make its mark on the justice system.

Mahiques' appointment may also signal a shift in the government's approach to justice and law enforcement, potentially affecting both political and judicial landscapes in Argentina. As the new Minister of Justice, Mahiques will be expected to navigate complex legal challenges amidst ongoing reforms in the national administration, making his role critical in shaping future policies and maintaining stability within the judicial framework.
