Back in the spring, Arkansas law professor Richard Peltz brought a defamation lawsuit against two law students who had circulated a letter accusing him of racism in the classroom. At the time, the students’ lawyer argued that a charge of racist behavior, “in the context of public discourse at a law school,” was not grounds for legal action.

Peltz requested and received an investigation of his actions by administrators, and in October the school’s interim dean gave Peltz a letter stating that his investigation had revealed “no evidence that you are or have been a racist … during your employment at the law school.”

Saying that he brought the lawsuit to force the university to take a stand on his behavior, Peltz then dropped the suit and circulated a nine-page memo responding to the charges that had been made against him.
