On 29 July 1993, a five-judge panel of the Israeli Supreme Court overturned the guilty verdict on appeal. The Supreme Court upheld the lower court's rulings on the authenticity of the Trawniki card and the falsity of Demjanjuk's alibi but ruled that reasonable doubt existed that Demjanjuk was Ivan the Terrible. The judges agreed that Demjanjuk most likely served as a Nazi "Wachmann" (guard) in the Trawniki unit and had been posted at Sobibor extermination camp and two other camps. Evidence to assist this claim included an identification card from Trawniki bearing Demjanjuk's picture and personal information – found in the Soviet archives – in addition to German documents that mentioned "Wachmann" Demjanjuk with his date and place of birth. The Trawniki certificate also implied that Demjanjuk had served at Sobibor, as did the German orders of March 1943 posting his Trawniki unit to the area. The court declined to find him guilty on this basis because the prosecution had built its entire case around Demjanjuk's identity with Ivan the Terrible, and Demjanjuk had not been given a chance to defend himself from charges of being a guard at Sobibor.
