Secular Frummy:
Bad example. Maran Habeit Yosef wrote the S”A without any “askanim” telling him how to pasken. However, mipnei avonoseinu harabim, the situation is such where we cannot trust that the signature of a gadol is real, or that said gadol understood what he was being asked to sign. Therefore, kol korehs are not worth very much. Sefarim are.
