ARGENTINA: New justice minister seeks to appoint 200 judges
Days after his appointment last week as Argentina’s new justice minister, Juan Bautista Mahiques has announced plans to appoint 200 new judges. Mahiques replaces Mariano Cúneo Libarona who served for two years. No specific public reason was given for the change, but it is known that the incumbent had wanted to step down for some time, and his departure was on friendly terms with President Javier Milei, who thanked him for “over two years of tireless work”.
The new man in the ministry is a former attorney general for the city of Buenos Aires and close associate of former president Mauricio Macri (2015-2019). He is also linked to a former president of Boca Juniors football team. On taking over the justice minister slot, Mahiques pledged to seek a “judicial system with clear and stable rules, which can rebuild public confidence and deliver real security and a predictable framework for those who obey the law”. As the Buenos Aires attorney general, Mahiques himself came under investigation in late 2022 for suspected “breach of duty as a public official and acceptance of gifts”.
- Lago Escondido case
The case in which Juan Bautista Mahiques came under investigation related to his acceptance of an invitation to the Lago Escondido mansion of Joe Lewis, a British tycoon [WR-22-49], in the Patagonian province of Río Negro, along with other officials including his father, Carlos Mahiques, a judge on the Cámara de Casación; federal judge Julián Ercolini, who indicted former president Cristina Fernández (2007-2015) for fraud and illicit association; and the then-justice and security minister of the government of the city of Buenos Aires, Marcelo D’Alessandro. The case was closed in December 2023 by a judge who ruled that the visit had been an entirely private matter.
The new minister lost no time in announcing appointments of new staff across the justice system. A total of 200 judges, 72 defence lawyers, and 65 public prosecutors will be recruited to fill existing vacancies. Candidates will be vetted to keep out any with a criminal record or with tax irregularities. The Council of Magistrates will then submit short lists for the president to select, with his choices subject to two-thirds majority endorsement in the senate. Mahiques says the main aim of the new appointments is to speed up the notoriously slow workings of the justice system.
Mahiques is also prioritising the government’s legal defence in a New York-based court case relating to state oil and gas company YPF and filed by investors Burford Capital (UK) and Eton Park Capital (US). The case is about alleged irregularities in the treatment of minority shareholders in the 2012 nationalisation of the company. In 2023 the court found Argentina liable, with damages later set at a near record US$16bn, a decision Argentina is appealing.
On Mahiques’ advice, President Milei has appointed Sebastián Amerio as the new treasury prosecutor (Procuración del Tesoro de la Nación – PTN) who will be a key figure presenting Argentina’s case. Under his guidance Argentina is seeking a postponement of the discovery process.
Labour reform signed into law
On 6 March President Milei signed the new labour reforms into law, after the approval of various drafts by the two chambers of congress. The last vote was in the senate, where the bill was approved in a 42-28 vote with two abstentions [WR-26-09].
The reforms seek to give employers greater flexibility to hire and fire, while reducing trade union powers. They replace the more than 50-year-old Labour Contracts Law of 1974. The government says they are vital to increase labour productivity and reduce informality (around 40% of the workforce is informal).
In the first two months of the year strikes and demonstrations were called to oppose the changes. However, the Confederación General del Trabajo (CGT) -the country’s main labour group - appears to have paused the protests temporarily, as it concentrates instead on a legal challenge.
CGT lawyers say the reform violates Article 14 of the constitution, which protects workers from arbitrary dismissal and guarantees minimum terms of employment. The unions also claim that the reforms may violate international agreements with the International Labour Organisation (ILO) to which Argentina is a party.
