Professor Davis points out, A System of Judicial Notice Based on Fairness and Convenience, in Perspectives of Law 69, 73 (1964), every case involves the use of hundreds or thousands of non-evidence facts. When a witness in an automobile accident case says “car,” everyone, judge and jury included, furnishes, from non-evidence sources within himself, the supplementing information that the “car” is an automobile, not a railroad car, that it is self-propelled, probably by an internal combustion engine, that it may be assumed to have four wheels with pneumatic rubber tires, and so on. The judicial process cannot construct every case from scratch, like Descartes creating a world based on the postulate Cogito, ergo sum. These items could not possibly be introduced into evidence, and no one suggests that they be. Nor are they appropriate subjects for any formalized treatment of judicial notice of facts. See Levin and Levy, Persuading the Jury with Facts Not in Evidence: The Fiction-Science Spectrum, 105 U.Pa.L.Rev. 139 (1956).
Professor Davis says:
“The reason we use trial-type procedure, I think, is that we make the practical judgement, on the basis of experience, that taking evidence, subject to cross-examination and rebuttal, is the best way to resolve controversies involving disputes of adjudicative facts, that is, facts pertaining to the parties. The reason we require a determination on the record is that we think fair procedure in resolving disputes of adjudicative facts calls for giving each party a chance to meet in the appropriate fashion the facts that come to the tribunal’s attention, and the appropriate fashion for meeting disputed adjudicative facts includes rebuttal evidence, cross-examination, usually confrontation, and argument (either written or oral or both). The key to a fair trial is opportunity to use the appropriate weapons (rebuttal evidence, cross-examination, and argument) to meet adverse materials that come to the tribunal’s attention.” A System of Judicial Notice Based on Fairness and Convenience, in Perspectives of Law 69, 93 (1964).
The rule proceeds upon the theory that these considerations call for dispensing with traditional methods of proof only in clear cases. Compare Professor Davis’ conclusion that judicial notice should be a matter of convenience, subject to requirements of procedural fairness. Id., 94.
