Corpse Exhumed then Put on Trial... WTF?

Pope Stephen VI sat in judgment of Formosus in 897, in what was called the Cadaver Synod. The corpse was disinterred, clad in papal vestments, and seated on a throne to face all the charges from John VIII. The verdict was that the deceased had been unworthy of the pontificate. The Damnatio memoriae, an old judicial practice from Ancient Rome, was applied to Formosus, all his measures and acts were annulled and the orders conferred by him were declared invalid. The papal vestments were torn from his body, the three fingers from his right hand that he had used in consecrations were cut off and the corpse was thrown into the Tiber (later to be retrieved by a monk).
