A number of people are involved in the Siri Proposition. Howeverm the man to the right, Fr. Peter Tran Van Khoat, is the pivotal figure. All of the evidence on the Siri proposition ultimately relies on the testimony of this one man. All previous witnesses are now dead, although new claims are being launched as to additional witnesses to Khoat's meeting with Siri in 1988. It should be noted that after that meeting, apparently Fr. Khoat was present at the consecration of four bishop by his good friend Archbishop Lefebvre. (Did he take a Papal Mandate from Siri to Lefebvre?)
