Note 476 — Chapter XXII · THE LAW OF PROCEDURE.
Reading edition
A conclusive presumption is sometimes called a presumptio juris et de jure, while a rebuttable presumption is distinguished as a presumptio juris. I am not aware of the origin or ground of this nomenclature. The so-called presumptio facti is not a legal presumption at all, but a mere provisional inference drawn by the court in the exercise of its unfettered judgment from the evidence before it.
