Quia propter

Acclamation was rare, and often driven more by crowd dynamics than discussion among the electors. Compromise committees were also rare, as they required unanimous agreement to be initiated (although, once formed, only two-thirds of the commission would be required). The requisite majority by balloting was considered a process for determining divine unanimity, that is, sanior et maior pars (Latin: sounder and greater part). The requirement of a two-thirds supermajority had been in place since the Third Lateran Council (1179), which followed the disputed election of Pope Alexander III.
