2847. A legal presumption is one that is specially attached by law to certain facts; it exempts the person in whose favour it exists from making any other proof.
A presumption concerning presumed facts is simple and may be rebutted by proof to the contrary; a presumption concerning deemed facts is absolute and irrebuttable.
