The Argentine Supreme Court overturned the acquittal of two former judges and two judicial workers of the country’s last dictatorship who had been involved in the process of illegal appropriation of Manuel Gonçalves Granada as a baby.

Gonçalves Granada, now 50, was born to dictatorship victims killed during an operation at their home in 1976. He is currently a human rights leader, member of the board of Grandmothers of Plaza de Mayo and head of the National Identity Commission, which is dedicated to finding babies stolen between 1976-1983.

Grandmothers of Plaza de Mayo celebrated the Supreme Court’s decision in a statement on Wednesday, saying the judges accepted the organization’s appeals and revoked the acquittals on Friday.

The move, they added, means there will be a new sentence of the former magistrates and judicial workers “respecting the principles of truth and justice.”

The decision affects former San Nicolás Juvenile Court judge Juan Carlos Marchetti, former Lomas de Zamora civil judge Juan Delfín Castro, and ex-juvenile advisors Juan Carlos Magni and Francisco García Cortina.
