Benedict had also previously been deposed by Sylvester III in 1044, and though he returned to take up the office again the next year, the Vatican considers Sylvester III to have been a legitimate pope in the intervening months (meaning that Benedict IX must be considered to have validly resigned by acquiescing to the deposition in 1044).
