Ordinarium Sanctae Romanae Ecclesiae is a document written by Jacobi Gaytani that furthered the development of the papal conclave by establishing a voting procedure currently referred to as "approval voting". The document is notable in that it is not a papal bull or decree but was treated as law by subsequent papal elections. Each round of voting was also treated as distinct; that is candidates remained eligible in all future scrutinies even if they had not received a single vote previously.
