Raúl Pleé, a federal prosecutor, is trying to revive a criminal complaint filed by Alberto Nisman, a prosecutor who died in mysterious circumstances earlier this year.
Mr. Nisman had accused former president Cristina
Fernandez de Kirchner, of trying to shield former Iranian officials that allegedly were involved in the 1994 bombing of a Jewish center, all in exchange for trade benefits.
Mr. Nisman’s complaint, which Mrs. Kirchner believed was part of a plot to destabilize her administration, dissolved in Argentina’s courts when a three-judge panel ruled unanimously to drop the case.
Mr. Nisman led the investigation into the 1994 bombing for a decade before he was found dead in January of a gunshot wound to the head at his apartment here. The investigation into his death, which thrust Argentina into a political crisis, has not established whether it was a suicide or murder.
Mr. Pleé filed to reopen the case based on new information related to negotiations between Argentina and Iran.
The new president, Mauricio Macri, had promised to revoke the pact. On Monday, the Justice Ministry ceased the appeal.
Pointing to the politicization of some legal cases in Argentina and the influence of the executive branch, Sergio Berensztein, a political analyst here, said the sequence of events that could lead to a revival of Mr. Nisman’s case would have been unlikely if Mrs. Kirchner’s party had beaten Mr. Macri in last month’s election.
