Juan Bautista Mahiques officially took the oath as Argentina's new Minister of Justice during a ceremony at the Casa Rosada, led by President Javier Milei. This appointment follows the departure of Mariano Cúneo Libarona, who was present at the event and participated in an embrace with both Mahiques and Milei after the swearing-in. The transition signifies a shift within Argentina's political landscape, particularly within the libertarian faction represented by Milei.

The decision to appoint Mahiques, alongside his deputy Santiago Viola, has been perceived as a consolidation of power by Karina Milei, the President's Secretary General, as they navigate internal party dynamics against the backdrop of adviser Santiago Caputo’s faction. Mahiques' ascension to the ministry is viewed as a strategic move to strengthen the government's legal and judicial stance, particularly in light of recent controversies involving his father, Carlos Mahiques, a prominent judge.

As the new Minister of Justice, Mahiques will face significant challenges, including reforming key aspects of the judicial system and addressing public concerns regarding the judiciary's integrity. His background and connections may also play a crucial role as the government seeks to implement changes that align with President Milei's broader libertarian agenda, which has generated extensive debate within Argentine politics.
