[4] In 2007, within the framework of the Causa Contraofensiva (proceedings involving charges relating to crimes committed against Montoneros), he was sentenced to 25 years in prison,[5] and in 2008, he was spared another trial,[6] but until the day he died, he had to live under house arrest, accused in various criminal cases.

On 30 November 1983. one week before leaving power and being demoted, Cristino Nicolaides signed the decree condemning Colonel Juan Jaime Cesio (57) for denouncing the disappearances.

Gangs made up of military officers have usurped the Government, and – with the mendacious purpose of fighting "subversion" – they committed aberrant crimes, such as kidnapping, torture and murder of thousands of persons.On 16 December 1983, Nicolaides was sent into retirement by the new constitutional (that is, not simply de facto) president, Raúl Alfonsín.

[16] Nevertheless, the last junta's members, and their last president, too, were indicted in connection with signing the so-called Final Document on the Fight against Subversion and Terrorism (Spanish: Documento Final sobre la Lucha contra la Subversión y el Terrorismo), and with sanctioning a "self-amnesty law" (Spanish: ley de autoamnistía) in 1983, under which they sought to grant themselves amnesty from prosecution before the new democratic government had a chance to try them for any wrongdoing.

Nicolaides was likewise accused of being responsible for the so-called Margarita Belén massacre and for the disappearances that took place at Regiment 9 in Corrientes while he held sway in the region,[19] but he died on 22 January 2011 at the age of 86, before the sentence was handed down, and was thus not named in it.
