While I agree that Jorge Bergoglio was invalidly elected, I do not agree with Archbishop Vigano that the cause was a “defect of consent”. Even if we assume that “defect of consent” is a valid cause, it is not the a priori cause. The a prior cause, rather, is that the Pope Benedict XVI did not validly renounce his munus (office). Therefore, no election could have legitimately been called in the first place.
