BUENOS AIRES, March 4 (Reuters) – Argentine President Javier Milei said on Wednesday he has appointed ​chief Buenos Aires prosecutor Juan Bautista ‌Mahiques as the country’s new justice minister.

Mahiques, who has been the attorney general of the Argentine capital since October 2019, will replace ‌Mariano ​Cuneo Libarona, who ⁠had been justice minister ⁠since December 2023, Milei announced in a posting on X.

Local newspaper La Nacion reported that Libarona had cited personal ​reasons for his departure.

“I assume this role with the conviction that without ⁠legal certainty there is ⁠no investment, without stable rules ​there is no development, and without independent ​judges there is no republic,” Mahiques ‌said in a separate post on X.

In a speech before Congress last Sunday, Milei announced that this year he ⁠will seek to pass more reforms to the penal code to introduce harsher sentences for ⁠criminals.

The ‌government won several legislative victories ⁠last week when Congress approved ​a ‌controversial labor reform and a ​change to ⁠the penal code that lowers the age of criminal responsibility from 16 to 14.
