The ARA San Juan (S-42) departed from the city of Ushuaia on an exercise and all contact with it was lost on November 15, 2017.
A search and rescue operation that lasted over a year was launched with the participation of 15 countries and the use of advanced technology.
Sometime after, the Ocean Infinity company was hired and found the remains of the submarine a year later.
The relatives of all 44 officers who died in the event are accusing Macri of alleged illegal surveillance against them while they waited for information on their loved ones.
A session on the case was scheduled for Tuesday, but it was postponed for April 26.
Martin Bava, judge of Dolores, Buenos Aires, prosecuted Macri on December 2021 for his direct responsibility in the illegal monitoring of the sailors’ relatives.
Bava stated that the former president ordered and made it possible, from his post, that intelligence tasks expressly prohibited by law were carried out, among which are obtaining and storing information on citizens selected for their political opinion or their membership in a party, social, trade union, community and human rights organizations.
