The Michigan Supreme Court has rejected a final appeal from sports doctor Larry Nassar, who was sentenced to decades in prison for sexually assaulting gymnasts, including Olympic medalists.

The court declined to take the case Friday.

Nassar says he was treated unfairly in 2018 and deserved a new hearing, based on provocative comments by a judge who called him a “monster.” Judge Rosemarie Aquilina said Nassar would “wither” in prison like the wicked witch in “The Wizard of Oz.”

She told Nassar that she had signed his death warrant with a 40-year sentence. Nassar pleaded guilty to sexually assaulting gymnasts, dancers and other athletes with his hands under the guise of medical treatments for hip and leg injuries.
