Rule 301 - Presumptions in general(a) Presumption defined. A presumption is an assumption of fact that the law requires to be made from another fact or group of facts found or otherwise established in the action or proceeding.(b) Classification and effect of presumptions. (1) Conclusive presumptions are presumptions that are specifically declared conclusive by statute. Conclusive presumptions may not be controverted.(2) All presumptions, other than conclusive presumptions, are disputable presumptions and may be controverted. A disputable presumption may be overcome by a preponderance of evidence contrary to the presumption. Unless the presumption is overcome, the trier of fact must find the assumed fact in accordance with the presumption.(c) Inconsistent presumptions. If presumptions are inconsistent the court shall apply the presumption that is founded upon weightier considerations of public policy. If considerations of public policy are of equal weight the court shall disregard both presumptions.Ad. Sup. Ct. Ord. 12729, Dec. 29, 1976, eff. July 1, 1977.
