1975-Pub. L. 94-149, § 1(1) to (8), Dec. 12, 1975, 89 Stat. 805, amended analysis as follows: Item 106, substituted "or" for "on"; Item 301, inserted "in" immediately after "general"; Item 405(a), inserted "or opinion" after "Reputation" and preceding the period; Item 410, substituted "Inadmissibility of pleas, offers of pleas, and related statements" for "Offer to plead guilty; nolo contendere; withdrawn plea of guilty"; Item 501, substituted "General rule"; Item 608(a), substituted "Opinion and reputation" for "Reputation"; Item 901(b)(8), substituted "compilation" for "compilations"; and Item 1101(c), substituted "Rule" for "Rules". ARTICLE I. GENERAL PROVISIONS Rule 101. Scope These rules govern proceedings in the courts of the United States and before United States magistrates, to the extent and with the exceptions stated in rule 1101. (Pub. L. 93-595, § 1, Jan. 2, 1975, 88 Stat. 1929.) NOTES OF ADVISORY COMMITTEE ON PROPOSED RULES Rule 1101 specifies in detail the courts, proceedings, questions, and stages of proceedings to which the rules apply in whole or in part. Rule 102. Purpose and Construction These rules shall be construed to secure fairness in administration, elimination of unjustifiable expense and delay, and promotion of growth and development of the law of evidence to the end that the truth may be ascertained and proceedings justly determined. (Pub. L. 93-595, § 1, Jan. 2, 1975, 88 Stat. 1929.) NOTES OF ADVISORY COMMITTEE ON PROPOSED RULES For similar provisions see Rule 2 of the Federal Rules of Criminal Procedure, Rule 1 of the Federal Rules of Civil Procedure, California Evidence Code § 2, and New Jersey Evidence Rule 5. Rule 103. Rulings on Evidence (a) Effect of erroneous ruling.-Error may not be predicated upon a ruling which admits or excludes evidence unless a substantial right of the party is affected, and (1) Objection.-In case the ruling is one admitting evidence, a timely objection or motion to strike appears of record, stating the specific ground of objection, if the specific ground was not apparent from the context; or (2) Offer of proof.-In case the ruling is one excluding evidence, the substance of the evidence was made known to the court by offer or was apparent from the context within which questions were asked. (b) Record of offer and ruling.-The court may add any other or further statement which shows the character of the evidence, the form in which it was offered, the objection made, and the ruling thereon. It may direct the making of an offer in question and answer form. (c) Hearing of jury.-In jury cases, proceedings shall be conducted, to the extent practicable, so as to prevent inadmissible evidence from being suggested to the jury by any means, such as making statements or offers of proof or asking questions in the hearing of the jury. (d) Plain error.-Nothing in this rule precludes taking notice of plain errors affecting substantial rights although they were not brought to the attention of the court. (Pub. L. 93-595, § 1, Jan. 2, 1975, 88 Stat. 1930.) NOTES OF ADVISORY COMMITTEE ON PROPOSED RULES Subdivision (a) states the law as generally accepted today. Rulings on evidence cannot be assigned as error unless (1) a substantial right is affected, and (2) the nature of the error was called to the attention of the judge, so as to alert him to the proper course of action and enable opposing counsel to take proper corrective measures. The objection and the offer of proof are the techniques for accomplishing these objectives. For similar provisions see Uniform Rules 4 and 5; California Evidence Code §§ 353 and 354; Kansas Code of Civil Procedure §§ 60-404 and 60-405. The rule does not purport to change the law with respect to harmless error. See 28 U.S.C. § 2111, F.R.Civ.P. 61, F.R.Crim.P. 52, and decisions construing them. The status of constitutional error as harmless or not is treated in Chapman v. California, 386 U.S. 18, 87 S.Ct. 824, 17 L.Ed.2d 705 (1967), reh. denied id. 987, 87 S.Ct. 1283, 18 L.Ed.2d 241. Subdivision (b). The first sentence is the third sentence of Rule 43(c) of the Federal Rules of Civil Procedure virtually verbatim. Its purpose is to reproduce for an appellate court, insofar as possible, a true reflection of what occurred in the trial court. The second sentence is in part derived from the final sentence of Rule 43(c). It is designed to resolve doubts as to what testimony the witness would have in fact given, and, in nonjury cases, to provide the appellate court with material for a possible final disposition of the case in the event of reversal of a ruling which excluded evidence. See 5 Moore's Federal Practice § 43.11 (2d ed. 1968). Application is made discretionary in view of the practical impossibility of formulating a satisfactory rule in mandatory terms. Subdivision (c). This subdivision proceeds on the supposition that a ruling which excludes evidence in a jury case is likely to be a pointless procedure if the excluded evidence nevertheless comes to the attention of the jury. Bruton v. United States, 389 U.S. 818, 88 S.Ct. 126, L.Ed.2d 70 (1968). Rule 43(c) of the Federal Rules of Civil Procedure provides: "The court may require the offer to be made out of the hearing of the jury." In re McConnell, 370 U.S. 230, 82 S.Ct. 1288, 8 L.Ed.2d 434 (1962), left some doubt whether questions on which an offer is based must first be asked in the presence of the jury. The subdivision answers in the negative. The judge can foreclose a particular line of testimony and counsel can protect his record without a series of questions before the jury, designed at best to waste time and at worst "to waft into the jury box" the very matter sought to be excluded. Subdivision (d). This wording of the plain error principle is from Rule 52(b) of the Federal Rules of Criminal Procedure. While judicial unwillingness to be constructed by mechanical breakdowns of the adversary system has been more pronounced in criminal cases, there is no scarcity of decisions to the same effect in civil cases. In general, see Campbell, Extent to Which Courts of Review Will Consider Questions Not Properly Raised and Preserved, 7 Wis.L.Rev. 91, 160 (1932); Vestal, Sua Sponte Consideration in Appellate Review, 27 Fordham L.Rev. 477 (1958-59); 64 Harv.L.Rev. 652 (1951). In the nature of things the application of the plain error rule will be more likely with respect to the admission of evidence than to exclusion, since failure to comply with normal requirements of offers of proof is likely to produce a record which simply does not disclose the error. Rule 104. Preliminary Questions (a) Questions of admissibility generally.-Preliminary questions concerning the qualification of a person to be a witness, the existence of a privilege, or the admissibility of evidence shall be determined by the court, subject to the provisions of subdivision (b). In making its determination it is not bound by the rules of evidence except those with respect to privileges. (b) Relevancy conditioned on fact.-When the relevancy of evidence depends upon the fulfillment of a condition of fact, the court shall admit it upon, or subject to, the introduction of evidence sufficient to support a finding of the fulfillment of the condition. (c) Hearing of jury.-Hearings on the admissibility of confessions shall in all cases be conducted out of the hearing of the jury. Hearings on other preliminary matters shall be so conducted when the interests of justice require or, when an accused is a witness, if he so requests. (d) Testimony by accused.-The accused does not, by testifying upon a preliminary matter, subject himself to cross-examination as to other issues in the case. (e) Weight and credibility.-This rule does not limit the right of a party to introduce before the jury evidence relevant to weight or credibility. (Pub. L. 93-595, § 1, Jan. 2, 1975, 88 Stat. 1930.) NOTES OF THE ADVISORY COMMITTEE ON PROPOSED RULES Subdivision (a). The applicability of a particular rule of evidence often depends upon the existence of a condition. Is the alleged expert a qualified physician? Is a witness whose former testimony is offered unavailable? Was a stranger present during a conversation between attorney and client? In each instance the admissibility of evidence will turn upon the answer to the question of the existence of the condition. Accepted practice, incorporated in the rule, places on the judge the responsibility for these determinations. McCormick § 53; Morgan, Basic Problems of Evidence 45-50 (1962). To the extent that these inquiries are factual, the judge acts as a trier of fact. Often, however, rulings on evidence call for an evaluation in terms of a legally set standard. Thus when a hearsay statement is offered as a declaration against interest, a decision must be made whether it possesses the required against-interest characteristics. These decisions, too, are made by the judge. In view of these considerations, this subdivision refers to preliminary requirements generally by the broad term "questions," without attempt at specification. This subdivision is of general application. It must, however, be read as subject to the special provisions for "conditional relevancy" in subdivision (b) and those for confessions in subdivision (d). If the question is factual in nature, the judge will of necessity receive evidence pro and con on the issue. The rule provides that the rules of evidence in general do not apply to this process. McCormick § 53, p. 123, n. 8, points out that the authorities are "scattered and inconclusive," and observes: "Should the exclusionary law of evidence, 'the child of the jury system' in Thayer's phrase, be applied to this hearing before the judge? Sound sense backs the view that it should not, and that the judge should be empowered to hear any relevant evidence, such as affidavits or other reliable hearsay." This view is reinforced by practical necessity in certain situations. An item, offered and objected to, may itself be considered in ruling on admissibility, though not yet admitted in evidence. Thus the content of an asserted declaration against interest must be considered in ruling whether it is against interest. Again, common practice calls for considering the testimony of a witness, particularly a child, in determining competency. Another example is the requirement of Rule 602 dealing with personal knowledge. In the case of hearsay, it is enough, if the declarant "so far as appears [has] had an opportunity to observe the fact declared." McCormick, § 10, p. 19. If concern is felt over the use of affidavits by the judge in preliminary hearings on admissibility, attention is directed to the many important judicial determinations made on the basis of affidavits. Rule 47 of the Federal Rules of Criminal Procedure provides: "An application to the court for an order shall be by motion. It may be supported by affidavit." The Rules of Civil Procedure are more detailed. Rule 43(e), dealing with motions generally, provides: "When a motion is based on facts not appearing of record the court may hear the matter on affidavits presented by the respective parties, but the court may direct that the matter be heard wholly or partly on oral testimony or depositions." Rule 4(g) provides for proof of service by affidavit. Rule 56 provides in detail for the entry of summary judgment based on affidavits. Affidavits may supply the foundation for temporary restraining orders under Rule 65(b). The study made for the California Law Revision Commission recommended an amendment to Uniform Rule 2 as follows: "In the determination of the issue aforesaid [preliminary determination], exclusionary rules shall not apply, subject, however, to Rule 45 and any valid claim of privilege." Tentative Recommendation and a Study Relating to the Uniform Rules of Evidence (Article VIII, Hearsay), Cal. Law Revision Comm'n, Rep., Rec. & Studies, 470 (1962). The proposal was not adopted in the California Evidence Code. The Uniform Rules are likewise silent on the subject. However, New Jersey Evidence Rule 8(1), dealing with preliminary inquiry by the judge, provides: "In his determination the rules of evidence shall not apply except for Rule 4 [exclusion on grounds of confusion, etc.] or a valid claim of privilege." Subdivision (b). In some situations, the relevancy of an item of evidence, in the large sense, depends upon the existence of a particular preliminary fact. Thus when a spoken statement is relied upon to prove notice to X, it is without probative value unless X heard it. Or if a letter purporting to be from Y is relied upon to establish an admission by him, it has no probative value unless Y wrote or authorized it. Relevance in this sense has been labelled "conditional relevancy." Morgan, Basic Problems of Evidence 45-46 (1962). Problems arising in connection with it are to be distinguished from problems of logical relevancy, e.g. evidence in a murder case that accused on the day before purchased a weapon of the kind used in the killing, treated in Rule 401. If preliminary questions of conditional relevancy were determined solely by the judge, as provided in subdivision (a), the functioning of the jury as a trier of fact would be greatly restricted and in some cases virtually destroyed. These are appropriate questions for juries. Accepted treatment, as provided in the rule, is consistent with that given fact questions generally. The judge makes a preliminary determination whether the foundation evidence is sufficient to support a finding of fulfillment of the condition. If so, the item is admitted. If after all the evidence on the issue is in, pro and con, the jury could reasonably conclude that fulfillment of the condition is not established, the issue is for them. If the evidence is not such as to allow a finding, the judge withdraws the matter from their consideration. Morgan, supra; California Evi dence Code § 403; New Jersey Rule 8(2). See also Uniform Rules 19 and 67. The order of proof here, as generally, is subject to the control of the judge. Subdivision (c). Preliminary hearings on the admissibility of confessions must be conducted outside the hearing of the jury. See Jackson v. Denno, 378 U.S. 368, 84 S.Ct. 1774, 12 L.Ed.2d 908 (1964). Otherwise, detailed treatment of when preliminary matters should be heard outside the hearing of the jury is not feasible. The procedure is time consuming. Not infrequently the same evidence which is relevant to the issue of establishment of fulfillment of a condition precedent to admissibility is also relevant to weight or credibility, and time is saved by taking foundation proof in the presence of the jury. Much evidence on preliminary questions, though not relevant to jury issues, may be heard by the jury with no adverse effect. A great deal must be left to the discretion of the judge who will act as the interests of justice require. Subdivision (d). The limitation upon cross-examination is designed to encourage participation by the accused in the determination of preliminary matters. He may testify concerning them without exposing himself to cross-examination generally. The provision is necessary because of the breadth of cross-examination under Rule 611(b). The rule does not address itself to questions of the subsequent use of testimony given by an accused at a hearing on a preliminary matter. See Walder v. United States, 347 U.S. 62 (1954): Simmons v. United States, 390 U.S. 377 (1968): Harris v. New York, 401 U.S. 222 (1971) Subdivision (e). For similar provisions see Uniform Rule 8; California Evidence Code § 406; Kansas Code of Civil Procedure § 60-408; New Jersey Evidence Rule 8(1). NOTES OF Committee on THE JUDICIARY, HOUSE Rule 104(c) as submitted to the Congress provided that hearings on the admissibility of confessions shall be conducted outside the presence of the jury and hearings on all other preliminary matters should be so conducted when the interests of justice require. The Committee amended the Rule to provide that where an accused is a witness as to a preliminary matter, he has the right, upon his request, to be heard outside the jury's presence. Although recognizing that in some cases duplication of evidence would occur and that the procedure could be subject to abuse, the Committee believed that a proper regard for the right of an accused not to testify generally in the case dictates that he be given an option to testify out of the presence of the jury on preliminary matters. The Committee construes the second sentence of subdivision (c) as applying to civil actions and proceedings as well as to criminal cases, and on this assumption has left the sentence unamended. NOTES OF COMMITTEE ON THE JUDICIARY, SENATE Under rule 104(c) the hearing on a preliminary matter may at times be conducted in front of the jury. Should an accused testify in such a hearing, waiving his privilege against self-incrimination as to the preliminary issue, rule 104(d) provides that he will not generally be subject to cross-examination as to any other issue. This rule is not, however, intended to immunize the accused from cross-examination where, in testifying about a preliminary issue, he injects other issues into the hearing. If he could not be cross-examined about any issues gratuitously raised by him beyond the scope of the preliminary matters, injustice result. Accordingly, in order to prevent any such unjust result, the committee intends the rule to be construed to provide that the accused may subject himself to cross-examination as to issues raised by his own testimony upon a preliminary matter before a jury. Rule 105. Limited Admissibility When evidence which is admissible as to one party or for one purpose but not admissible as to another party or for another purpose is admitted, the court, upon request, shall restrict the evidence to its proper scope and instruct the jury accordingly. (Pub. L. 93-595, § 1, Jan. 2, 1975, 88 Stat. 1930.) NOTES OF ADVISORY COMMITTEE ON PROPOSED RULES A close relationship exists between this rule and Rule 403 which requires exclusion when "probative value is substantially outweighed by the danger of unfair prejudice, confusion of the issues, or misleading the jury." The present rule recognizes the practice of admitting evidence for a limited purpose and instructing the jury accordingly. The availability and effectiveness of this practice must be taken into consideration in reaching a decision whether to exclude for unfair prejudice under Rule 403. In Bruton v. United States, 389 U.S. 818, 88 S.Ct. 126, 19 L.Ed.2d 70 (1968), the Court ruled that a limiting instruction did not effectively protect the accused against the prejudicial effect of admitting in evidence the confession of a codefendant which implicated him. The decision does not, however, bar the use of limited admissibility with an instruction where the risk of prejudice is less seri ous. Similar provisions are found in Uniform Rule 6; California Evidence Code § 355; Kansas Code of Civil Procedure § 60-406; New Jersey Evidence Rule 6. The wording of the present rule differs, however, in repelling any implication that limiting or curative instructions are sufficient in all situations. NOTES OF COMMITTEE ON THE JUDICIARY, HOUSE Rule 106 as submitted by the Supreme Court (now Rule 105 in the bill) dealt with the subject of evidence which is admissible as to one party or for one purpose but is not admissible against another party or for another purpose. The Committee adopted this Rule without change on the understanding that it does not affect the authority of a court to order a severence in a multi-defendant case. Rule 106. Remainder of or Related Writings or Recorded Statements When a writing or recorded statement or part thereof is introduced by a party, an adverse party may require him at that time to introduce any other part or any other writing or recorded statement which ought in fairness to be considered contemporaneously with it. (Pub. L. 93-595, § 1, Jan. 2, 1975, 88 Stat. 1930.) NOTES OF ADVISORY COMMITTEE ON PROPOSED RULES The rule is an expression of the rule of completeness. McCormick § 56. It is manifested as to depositions in Rule 32(a)(4) of the Federal Rules of Civil Procedure, of which the proposed rule is substantially a restatement. The rule is based on two considerations. The first is the misleading impression created by taking matters out of context. The second is the inadequacy of repair work when delayed to a point later in the trial. See McCormick § 56; California Evidence Code 356. The rule does not in any way circumscribe the right of the adversary to develop the matter on cross-examination or as part of his own case. For practical reasons, the rule is limited to writings and recorded statements and does not apply to conversations. ARTICLE II. JUDICIAL NOTICE Rule 201. Judicial Notice of Adjudicative Facts (a) Scope of rule.-This rule governs only judicial notice of adjudicative facts. (b) Kinds of facts.-A judicially noticed fact must be one not subject to reasonable dispute in that it is either (1) generally known within the territorial jurisdiction of the trial court or (2) capable of accurate and ready determination by resort to sources whose accuracy cannot reasonably be questioned. (c) When discretionary.-A court may take judicial notice, whether requested or not. (d) When mandatory.—A court shall take judicial notice if requested by a party and supplied with the necessary information. (e) Opportunity to be heard.—A party is entitled upon timely request to an opportunity to be heard as to the propriety of taking judicial notice and the tenor of the matter noticed. In the absence of prior notification, the request may be made after judicial notice has been taken. (f) Time of taking notice.-Judicial notice may be taken at any stage of the proceeding. (g) Instructing jury.—In a civil action or proceeding, the court shall instruct the jury to accept as conclusive any fact judicially noticed. In a criminal case, the court shall instruct the jury that it may, but is not required to, accept as conclusive any fact judicially noticed. (Pub. L. 93-595, § 1, Jan. 2, 1975, 88 Stat. 1930.) NOTES OF ADVISORY COMMITTEE on Proposed RULES Subdivision (a). This is the only evidence rule on the subject of judicial notice. It deals only with judicial notice of “adjudicative" facts. No rule deals with judicial notice of "legislative" facts. Judicial notice of matters of foreign law is treated in Rule 44.1 of the Federal Rules of Civil Procedure and Rule 26.1 of the Federal Rules of Criminal Procedure. The omission of any treatment of legislative facts results from fundamental differences between adjudicative facts and legislative facts. Adjudicative facts are simply the facts of the particular case. Legislative facts, on the other hand, are those which have relevance to legal reasoning and the lawmaking process, whether in the formulation of a legal principle or ruling by a judge or court or in the enactment of a legislative body. The terminology was coined by Professor Kenneth Davis in his article An Approach to Problems of Evidence in the Administrative Process, 55 Harv.L.Rev. 364, 404-407 (1942). The following discussion draws extensively upon his writings. In addition, see the same author's Judicial Notice, 55 Colum.L. Rev. 945 (1955); Administrative Law Treatise, ch. 15 (1958); A System of Judicial Notice Based on Fairness and Convenience, in Perspectives of Law 69 (1964). The usual method of establishing adjudicative facts in through the introduction of evidence, ordinarily consisting of the testimony of witnesses. If particular facts are outside of reasonable controversy, this process is dispensed with as unnecessary. A high degree of indisputability is the essential prerequisite. Legislative facts are quite different. As Professor Davis says: "My opinion is that judge-made law would stop growing if judges, in thinking about questions of law and policy, were forbidden to take into account the facts they believe, as distinguished from facts which are 'clearly within the domain of the indisputable. Facts most needed in thinking about difficult problems of law and policy have a way of being outside the domain of the clearly indisputable." A System of Judicial Notice Based on Fairness and Convenience, supra, at 82. An illustration is Hawkins v. United States, 358 U.S. 74, 79 S.Ct. 136, 3 L.Ed.2d 125 (1958), in which the Court refused to discard the common law rule that one spouse could not testify against the other, saying, "Adverse testimony given in criminal proceedings would, we think, be likely to destroy almost any marriage." This conclusion has a large intermixture of fact, but the factual aspect is scarcely "indisputable." See Hutchins and Slesinger, Some Observations on the Law of Evidence-Family Relations, 13 Minn.L.Rev. 675 (1929). If the destructive effect of the giving of adverse testimony by a spouse is not indisputable, should the Court have refrained from considering it in the absence of supporting evidence? "If the Model Code or the Uniform Rules had been applicable, the Court would have been barred from thinking about the essential factual ingredient of the problems before it, and such a result would be obviously intolerable. What the law needs as its growing points is more, not less, judicial thinking about the factual ingredients of problems of what the law ought to be, and the needed facts are seldom 'clearly' indisputable." Davis, supra, at 83. "Professor Morgan gave the following description of the methodology of determining domestic law: "In determining the content or applicability of a rule of domestic law, the judge is unrestricted in his investigation and conclusion. He may reject the propositions of either party or of both parties. He may consult the sources of pertinent data to which they refer, or he may refuse to do so. He may make an independent search for persuasive data or rest content with what he has or what the parties present. ・・・ [T]he parties do no more than to assist; they control no part of the process." Morgan, Judicial Notice, 57 Harv.L.Rev. 269, 270-271 (1944). This is the view which should govern judicial access to legislative facts. It renders inappropriate any limitation in the form of indisputability, any formal requirements of notice other than those already inherent in affording opportunity to hear and be heard and exchanging briefs, and any requirement of formal findings at any level. It should, however, leave open the possibility of introducing evidence through regular channels in appropriate situations. See Borden's Farm Products Co. v. Baldwin, 293 U.S. 194, 55 S.Ct. 187, 79 L.Ed. 281 (1934), where the cause was remanded for the taking of evidence as to the economic conditions and trade practices underlying the New York Milk Control Law. Similar considerations govern the judicial use of nonadjudicative facts in ways other than formulating laws and rules. Thayer described them as a part of the judicial reasoning process. "In conducting a process of judicial reasoning, as of other reasoning, not a step can be taken without assuming something which has not been proved; and the capacity to do this with competent judgement and efficiency, is imputed to judges and juries as part of their necessary mental outfit." Thayer, Preliminary Treatise on Evidence 279-280 (1898). As 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). Another aspect of what Thayer had in mind is the use of non-evidence facts to appraise or assess the adjudicative facts of the case. Pairs of cases from two jurisdictions illustrate this use and also the difference between non-evidence facts thus used and adjudicative facts. In People v. Strook, 347 Ill. 460, 179 N.E. 821 (1932), venue in Cook County had been held not established by testimony that the crime was committed at 7956 South Chicago Avenue, since judicial notice would not be taken that the address was in Chicago. However, the same court subsequently ruled that venue in Cook County was established by testimony that a crime occurred at 8900 South Anthony Avenue, since notice would be taken of the common practice of omitting the name of the city when speaking of local addresses, and the witness was testifying in Chicago. People v. Pride, 16 Ill.2d 82, 156 N.E.2d 551 (1951). And in Hughes v. Vestal, 264 N.C. 500, 142 S.E.2d 361 (1965), the Supreme Court of North Carolina disapproved the trial judge's admission in evidence of a state-published table of automobile stopping distances on the basis of judicial notice, though the court itself had referred to the same table in an earlier case in a "rhetorical and illustrative" way in determining that the defendant could not have stopped her car in time to avoid striking a child who suddenly appeared in the highway and that a non-suit was properly granted. Ennis v. Dupree, 262 N.C. 224, 136 S.E.2d 702 (1964). See also Brown v. Hale, 263 N.C. 176, 139 S.E.2d 210 (1964); Clayton v. Rimmer, 262 N.C. 302, 136 S.E.2d 562 (1964). It is apparent that this use of non-evidence facts in evaluating the adjudicative facts of the case is not an appropriate subject for a formalized judicial notice treatment. In view of these considerations, the regulation of judicial notice of facts by the present rule extends only to adjudicative facts. What, then, are “adjudicative" facts? Davis refers to them as those "which relate to the parties," or more fully: "When a court or an agency finds facts concerning the immediate parties-who did what, where, when, how, and with what motive or intent-the court or agency is performing an adjudicative function, and the facts are conveniently called adjudicative facts. * "Stated in other terms, the adjudicative facts are those to which the law is applied in the process of adjudication. They are the facts that normally go to the jury in a jury case. They relate to the parties, their activities, their properties, their businesses." 2 Administrative Law Treatise 353. Subdivision (b). With respect to judicial notice of adjudicative facts, the tradition has been one of caution in requiring that the matter be beyond reasonable controversy. This tradition of circumspection appears to be soundly based, and no reason to depart from it is apparent. As 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. This rule is consistent with Uniform Rule 9(1) and (2) which limit judicial notice of facts to those "so universally known that they cannot reasonably be the subject of dispute," those "so generally known or of such common notoriety within the territorial jurisdiction of the court that they cannot reasonably be the subject of dispute," and those "capable of immediate and accurate determination by resort to easily accessible sources of indisputable accuracy." The traditional textbook treatment has included these general categories (matters of common knowledge, facts capable of verification), McCormick §§ 324, 325, and then has passed on into detailed treatment of such specific topics as facts relating to the personnel and records of the court, Id. § 327, and other governmental facts, Id. § 328. The California draftsmen, with a background of detailed statutory regulation of judicial notice, followed a somewhat similar pattern. California Evidence Code 451, 452. The Uniform Rules, however, were drafted on the theory that these particular matters are included within the general categories and need no specific mention. This approach is followed in the present rule. The phrase "propositions of generalized knowledge," found in Uniform Rule 9(1) and (2) is not included in the present rule. It was, it is believed, originally included in Model Code Rules 801 and 802 primarily in order to afford some minimum recognition to the right of the judge in his "legislative" capacity (not acting as the trier of fact) to take judicial notice of very limited categories of generalized knowledge. The limitations thus imposed have been discarded herein as undesirable, unworkable, and contrary to existing practice. What is left, then, to be considered, is the status of a "proposition of generalized knowledge" as an "adjudicative" fact to be noticed judicially and communicated by the judge to the jury. Thus viewed, it is considered to be lacking practical significance. While judges use judicial notice of "propositions of generalized knowledge" in a variety of situations: determining the validity and meaning of statutes, formulating common law rules, deciding whether evidence should be admitted, assessing the sufficiency and effect of evidence, all are essentially nonadjudicative in nature. When judicial notice is seen as a significant vehicle for progress in the law, these are the areas involved, particularly in developing fields of scientific knowledge. See McCormick 712. It is not believed that judges now instruct juries as to "propositions of generalized knowledge" derived from encyclopedias or other sources, or that they are likely to do so, or, indeed, that it is desirable that they do so. There is a vast difference between ruling on the basis of judicial notice that radar evidence of speed is admissible and explaining to the jury its principles and degree of accuracy, or between using a table of stopping distances of automobiles at various speeds in a judicial evaluation of testimony and telling the jury its precise application in the case.
