The three judges of the National Chamber of Criminal Cassation Tuesday unanimously opted to close the file regarding a complaint filed by the late prosecutor Alberto Nisman against President Fernandez.
Nisman had accused the president of orchestrating a cover-up in relation to the 1994 bombing of a Jewish community center in Buenos Aires.
The decision by the high level court affirms several rulings by lower courts that determined there was no evidence of a crime by the president.
Prosecuting attorney Javier de Luca said in April that none of the events in Nisman's report constitute a crime.
Judge Daniel Rafecas, who first reviewed and dismissed the complaint, said that there was no reason to continue with the investigation, because the documents originally filed by Nisman did not meet the necessary standards for a criminal investigation.
Nisman, who was found dead in his apartment in January in an apparent suicide, accused President Fernandez, Foreign Minister Hector Timerman and Congressman Andres Larroque of deliberately covering-up the alleged role of a group of Iranians in the bombing due to a secret deal with the Iranian government.
In a broadcast to the country, President Fernandez rejected any notion of a secret deal in exchange for oil and affirmed that Iranian oil cannot even be refined in Argentina.
Opposition politicians opportunistically accused the president of having Nisman killed as a result of his accusations. However, forensic experts recently concluded that Nisman likely died as a result of a self-inflicted gunshot.
