903.01903.01Presumptions in general. Except as provided by statute, a presumption recognized at common law or created by statute, including statutory provisions that certain basic facts are prima facie evidence of other facts, imposes on the party relying on the presumption the burden of proving the basic facts, but once the basic facts are found to exist the presumption imposes on the party against whom it is directed the burden of proving that the nonexistence of the presumed fact is more probable than its existence.
903.01 HistoryHistory: Sup. Ct. Order, 59 Wis. 2d R1, R41 (1973).
903.01 AnnotationThis section does not apply to the presumption in favor of traveling employees under s. 102.03 (1) (f). Goranson v. DILHR, 94 Wis. 2d 537, 289 N.W.2d 270 (1980).
903.01 AnnotationConflicting presumptions should rarely present a problem. Under this section it is impossible for opposing parties to both have the burden of persuasion on the same issue. Should inconsistent presumptions be established in a case, the weight of the evidence establishing the facts upon which the presumptions are premised is for the trier of fact and not the judge with respect to the law. Marine Bank v. Taz’s Trucking Incorporated, 2005 WI 65, 281 Wis. 2d 275, 697 N.W.2d 90, 03-2827.
