(AP) — The Nebraska Supreme Court has again dismissed an appeal by a former University of Nebraska Medical Center student who says the school discriminated against him when it kicked him out.

The student filed the lawsuit after he was dismissed in 2006 for poor performance. He filed anonymously as John Doe and served as his own attorney, accusing UNMC, various staff members and the university Board of Regents of breach of contract, fraudulent concealment and violating the federal Americans with Disabilities Act.

Doe says he told officials he was chronically depressed, but school officials denied that.

The state’s high court previously rejected Doe’s breach of contract and fraudulent concealment claims. On Friday, it found that a lower court was right to dismiss Doe’s remaining discrimination claim.
