The Wisconsin Supreme Court has upheld a sexual abuse conviction of a former Jesuit priest who claimed he was falsely accused.

In a 7-0 ruling on Tuesday, justices ruled that Donald McGuire's prosecution 36 years after he allegedly abused two teenage boys in the 1960s was fair.

McGuire, a former spiritual adviser to Mother Teresa and her religious order of nuns, argued the delay hurt his ability to defend himself. Justices disagreed.

The men came forward in 2003 to report they were abused by McGuire during trips to a cottage in Fontana, Wis. in 1967 and 1968. At the time, McGuire taught the boys at the Loyola Academy in Wilmette, Ill.

McGuire was convicted on five counts of indecent behavior with a child. He is serving a 25-year prison term on separate, federal charges.
