BUENOS AIRES, Argentina (JTA) — Jewish organizations in Argentina petitioned the country’s federal court to order the government to stop its joint probe with Iran of the 1994 terrorist attack on the Buenos Aires JCC.

The Buenos Aires center AMIA and the national Jewish political umbrella group DAIA filed a joint petition on April 4 with the Federal Administrative Court, arguing that Argentina’s Congress acted unconstitutionally in voting for the memorandum of understanding launching the probe. Argentina had signed the pact with Iran in January.

Miguel Bronfman, the lawyer representing the institutions, told JTA that two additional motions seeking an injunction were filed to stop the government from further advancing its cooperation with Iran.

Also on April 4, DAIA President Julio Schlosser urged state prosecutor Alberto Nisman to release a report that Schlosser said “contains irrefutable evidence against Iran.”
