Yale University is off the hook for mistakenly confirming the credentials of an art history professor to a South Korean university.

The 2nd Circuit ruled on Thursday that the Ivy League institution was not guilty of negligence, defamation and reckless conduct in the case, since its administrators did not act with actual malice when confirming the degree.

Dongguk University filed suit in 2008, claiming that it was “publicly humiliated and deeply shamed in the eyes of the Korean population” after it came to light that one of its professors, Shin Jeong-ah, had lied about receiving her doctorate from Yale.
