Claim: The Ordinarium Sanctae Romanae Ecclesiae written by Jacobi Gaytani, placed no restrictions on the amount of candidates a cardinal could involve.
Evidence: 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". Gaytani (a participant in five papal conclaves between 1305 and 1352) included no restriction on the number of candidates a cardinal could include on his ballot during a scrutiny, but advised not to choose too many "for decency and expediency".
