After Pope Benedict XVI announced his resignation, on 25 February 2013, he issued another decree, "Normas nonnullas", which allowed the College of Cardinals to bring forward the start of a conclave once all cardinals are present or delay the start a few days if serious reasons justify the change in scheduling. He also amended the rules to declare automatic excommunication of any non-cardinal who broke the oath of secrecy of the College of Cardinals during the proceedings. Previously any such person was subject to punishment at the discretion of the new pope. The new rules were first applied in the 2013 conclave that elected Pope Francis.
