Fr. Jean-Marie Charles-Roux, a former Vatican official and intelligence officer claimed that Cardinal Siri of Genoa had been elected and also *accepted the Papal office, but was then immediately shoved aside, **without his actually abdicating. According to Fr. Charles-Roux, a very serious threat was delivered to Siri and the assembled Cardinals through Cardinal Tisserant, the Dean of the Sacred College of Cardinals, shortly after the acceptance of office by the new Pope. Conclave ministers had already begun to burn the ballots with dry straw in the Sistine Chapel stove, sending up white smoke to announce the election of the Pope. Even as the thunderous cheers of the crowd outside could be heard by those inside the conclave, a group of cardinals in league with Tisserant commanded the ministers to change the mixture in the stove to wet straw in order to produce black smoke. When the conclave officials refused the order to send out a false signal that would indicate no electoral results, a group of Cardinals brushed the monsignors aside and began to dump wet straw into the stove. Thereafter, a “shoving match” ensued over control of the stove, and the alternating mixtures of dry and wet straw that were being put into it, caused the smoke to vary from white, to black, to white again, and finally to gray, he said.

Thus, in the state of grave fear that was unjustly inflicted upon Pope Gregory XVII (which lasted his entire pontificacy), he could NOT (by law) resign His Office as Pope - even if he desired to - as the Church's Canon Law decrees:
