The Rehabilitation trial of Joan of Arc (also known as the Nullification trial of Joan of Arc), held in 1455-56, refers to the hearings conducted by a Papal Commission appointed by Pope Calixtus III for the purpose of examining the circumstances surrounding, and conduct of, the 1431 Trial of Joan of Arc at which she was condemned as a heretic and burned at the stake. In the end, the Commission set aside the original sentence on Joan, declaring the original twelve articles of the indictment to be "iniquitous, false, prepared in a lying manner and without reference to Joan's confessions."
