After being forced to leave his position as deputy Justice Minister, Sebastián Amerio will become the new Treasury Prosecutor amid a restructuring driven by Karina Milei. Juan Bautista Mahiques assumed as Justice Minister and requested mass resignations from officials. The move highlights internal tensions in La Libertad Avanza between Karina Milei and Santiago Caputo.
Juan Bautista Mahiques assumed as Justice Minister on March 5, 2026, with Karina Milei's approval, and immediately requested resignations from heads of key agencies like the Anti-Corruption Office, the Financial Information Unit, and the General Justice Inspection. This aims to place loyal figures in sensitive areas, though the Treasury Prosecutor's Office remained untouched due to its delicacy in state litigations. Sebastián Amerio, seen as close to Santiago Caputo, leaves the deputy ministry to replace Santiago Castro Videla as Treasury Prosecutor, allowing Caputo to retain influence despite the internal libertarian defeat.
Santiago Viola, another ally of Karina Milei and the Menem family, will take the Justice Secretariat and represent the Executive in the Magistracy Council to speed up filling over 300 judicial vacancies. Mahiques stressed on his X account the need for independent and impartial justice: “Without justice, there is no possible future. That course demands institutions that function in accordance with the Rule of Law.” He thanked Javier Milei, Karina Milei, and his predecessor Mariano Cúneo Libarona.
Deputy Rodolfo Tailhade criticized the changes on a Canal E program, stating that Karina Milei delegates control to a “judicial corporation” linked to Comodoro Py, with possible ties to the Macri era and risks of opposition persecution. Tailhade pointed to networks of judicial operators with political influence, citing the Lago Escondido scandal as an example of these dynamics. The planning was conducted secretly between Karina Milei and Caputo, prioritizing judicial nominations requiring only a simple majority in the Senate.
