The University of California, Berkeley law school's former dean has filed a lawsuit accusing school officials of singling him out because of his race for a second investigation of sexual harassment allegations.

Sujit Choudhry says in a federal discrimination lawsuit filed Thursday in San Francisco that the University of California has treated white faculty members and administrators found to have committed sexual misconduct more leniently while threatening him with a campus ban and loss of tenure.

His lawsuit names the University of California regents and President Janet Napolitano and seeks unspecified damages.

A message seeking comment from the University of California was not immediately returned.

Choudhry resigned as dean in March amid faculty outrage that he had been allowed to remain in the position after a campus investigation substantiated sexual harassment allegations from his executive assistant.
