Denver (AP) - A judge has refused to reinstate a University of Colorado professor who was fired on plagiarism charges after he likened some Sept. 11 victims to a Nazi.

Tuesday's ruling means Ward Churchill can't return to the classroom even though a jury ruled in April that his firing was politically motivated.

Churchill wrote an essay after the 2001 terrorist attacks calling the World Trade Center victims ``little Eichmanns,'' a reference to Adolf Eichmann, the Nazi leader who orchestrated the Holocaust.

The University fired Churchill in 2007 on the plagiarism charges and other research misconduct allegations. None of the allegations were about the Sept. 11 essay.
