A U.S. civil rights institution slammed the law school appointment of the former U.S. deputy attorney general, claiming he is unworthy of the post because of his role in sending Canadian Maher Arar to Syria to be tortured.

"The Center for Constitutional Rights is profoundly concerned at the news that the University of Georgia School of Law has hired former deputy attorney general Larry Thompson as a permanent member of its law school faculty," Maria LaHood, senior staff attorney for the institution and counsel to Arar, said in a statement.

U.S. officials detained Arar in 2002 during a stopover at John F. Kennedy airport in New York, claiming he had links to al-Qaeda. He was then deported to Syria, where he was jailed and tortured.

Thompson, deputy attorney general at the time, signed off on the decision to send Arar to Syria.

"It would be shocking if the law school were aware of Mr. Thompson’s role in this case and hired him nonetheless," LaHood said.

"The notion that Mr. Thompson should be held out as a model for future law students when in fact he should be, at a bare minimum, investigated for his role in Mr. Arar’s rendition to torture, is astonishing."

LaHood called on the law school to investigate and reconsider the appointment of Thompson.

"Anything short of a full investigation into this matter would bring into question the integrity of the University of Georgia School of Law."
