A longtime professor at The John Marshall Law School in Chicago has filed suit, claiming administrators violated the Americans With Disabilities Act when they declined to accommodate his depression and Asperger’s syndrome.

Joel Cornwell has taught at the school since 1985 but was suspended from teaching and barred from ­campus in October following a series of dustups with students and administrators that he attributes to his mild form of Asperger’s. He says the condition makes it hard for him to pick up on nonverbal cues and impairs his social interactions.
