(AP) — A federal appeals court has upheld the dismissal of a psychiatric patient’s lawsuit, filed after he lost his unsupervised walks on hospital grounds.

John Maxwell Montin’s sued Lincoln Regional Center administrators after being told in 1996 he could no longer walk the center’s grounds alone. A federal judge dismissed the lawsuit last year, ruling that revoking the solo walks did not deprive him of his due process and equal protection rights.

Montin was sent to the psychiatric hospital in 1994 after being found not responsible for attempted murder and other counts by reason of insanity in 1993.

A year earlier, authorities say Montin walked onto southwestern Nebraska farm, saying it belonged to his ancestors and that he was taking it back. A shootout with police followed. No one was injured.
