In 2017
Amnesty International published an investigation of the
1988 executions of Iranian political prisoners, documenting how Mahallati denied that Iran was conducting mass executions during his tenure as Permanent Representative to the United Nations. Instead, Mahallati claimed that the 1988 executions were "battlefield killings" and called the United Nation's resolution expressing concern over the matter "unjust" because it was based on "fake information" released by "a terrorist organization in Iraq." On October 7, 2020, a group of former Iranian political prisoners and human rights activists sent a letter to the president of Oberlin College demanding that the college terminate Mahallati's employment. Referencing the Amnesty International report, the letter argued he intended to "obfuscate and lie to the international community about mass crimes perpetrated by the Iranian regime." On October 10, 2020, Mahallati responded to this allegation, saying, "The accusers fail to provide a single solid document as evidence of my actual knowledge of these incidents. With no concrete evidence, they infer that I must have been informed of and intentionally denied these atrocities. I categorically deny any knowledge and therefore responsibility regarding mass executions in Iran when I was serving at the United Nations." To investigate the matter, Oberlin hired the law firm
Greenberg Traurig to review Mahallati's case which came to the conclusion that there was no support to these accusations. On November 2, 2021, protestors demanded Oberlin provide "full transparency of (Mahallati's) criminal past" and graphically reenacted the Iranian trials on the college's campus. In December 2023, Oberlin College placed Mahallati on indefinite leave following allegations that he ran a sex-for-grade scheme while previously teaching at
Columbia University. ==Works==
