fornia Evidence Code § 770 and New Jersey Evidence Rule 22(b).

Under principles of expression unius the rule does not apply to impeachment by evidence of prior inconsistent conduct. The use of inconsistent statements to impeach a hearsay declaration is treated in Rule 806.

Rule 614. Calling and Interrogation of Witnesses by Court

(a) Calling by court.-The court may, on its own motion or at the suggestion of a party, call witnesses, and all parties are entitled to crossexamine witnesses thus called.

(b) Interrogation by court.-The court may interrogate witnesses, whether called by itself or by a party.

(c) Objections.-Objections to the calling of witnesses by the court or to interrogation by it may be made at the time or at the next available opportunity when the jury is not present. (Pub. L. 93-595, § 1, Jan. 2, 1975, 88 Stat. 1937.) NOTES OF ADVISORY COMMITTEE on PROPOSED RULES Subdivision (a). While exercised more frequently in criminal than in civil cases, the authority of the judge to call witnesses is well established. McCormick § 8, p. 14; Maguire, Weinstein, et al., Cases on Evidence 303-304 (5th ed. 1965); 9 Wigmore § 2484. One reason for the practice, the old rule against impeaching one's own witness, no longer exists by virtue of Rule 607, supra. Other reasons remain, however, to justify the continuation of the practice of calling court's witnesses. The right to cross-examine, with all it implies, is assured. The tendency of juries to associate a witness with the party calling him, regardless of technical aspects of vouching, is avoided. And the judge is not imprisoned within the case as made by the parties.

Subdivision (b). The authority of the judge to question witnesses is also well established. McCormick § 8, pp. 12-13; Maguire, Weinstein, et al., Cases on Evidence 737-739 (5th ed. 1965); 3 Wigmore § 784. The authority is, of course, abused when the judge abandons his proper role and assumes that of advocate, but the manner in which interrogation should be conducted and the proper extent of its exercise are not susceptible of formulation in a rule. The omission in no sense precludes courts of review from continuing to reverse for abuse.

Subdivision (c). The provision relating to objections is designed to relieve counsel of the embarrassment attendant upon objecting to questions by the judge in the presence of the jury, while at the same time assuring that objections are made in apt time to afford the opportunity to take possible corrective measures. Compare the "automatic" objection feature of Rule 605 when the judge is called as a witness.

Rule 615. Exclusion of Witnesses

At the request of a party the court shall order witnesses excluded so that they cannot hear the testimony of other witnesses, and it may make the order of its own motion. This rule does not authorize exclusion of (1) a party who is a natural person, or (2) an officer or employee of a party which is not a natural person designated as its representative by its attorney, or (3) a person whose presence is shown by a party to be essential to the presentation of his

cause.

(Pub. L. 93-595, § 1, Jan. 2, 1975, 88 Stat. 1937.) NOTES OF ADVISORY COMMITTEE ON PROPOSED RULES The efficacy of excluding or sequestering witnesses has long been recognized as a means of discouraging

and exposing fabrication, inaccuracy, and collusion. 6 Wigmore §§ 1837-1838. The authority of the judge is admitted, the only question being whether the matter is committed to his discretion or one of right. The rule takes the latter position. No time is specified for making the request.

Several categories of persons are excepted. (1) Exclusion of persons who are parties would raise serious problems of confrontation and due process. Under accepted practice they are not subject to exclusion. 6 Wigmore § 1841. (2) As the equivalent of the right of a natural-person party to be present, a party which is not a natural person is entitled to have a representative present. Most of the cases have involved allowing a police officer who has been in charge of an investigation to remain in court despite the fact that he will be a witness. United States v. Infanzon, 235 F.2d 318 (2d Cir. 1956); Portomene v. United States, 221 F.2d 582 (5th Cir. 1955); Powell v. United States, 208 F.2d 618 (6th Cir. 1953); Jones v. United States, 252 F.Supp. 781 (W.D.Okl. 1966). Designation of the representative by the attorney rather than by the client may at first glance appear to be an inversion of the attorney-client relationship, but it may be assumed that the attorney will follow the wishes of the client, and the solution is simple and workable. See California Evidence Code § 777. (3) The category contemplates such persons as an agent who handled the transaction being litigated or an expert needed to advise counsel in the management of the litigation. See 6 Wigmore § 1841, n. 4.

NOTES OF COMMITTEE ON THE JUDICIARY, SENATE
REPORT NO. 93-1277

Many district courts permit government counsel to have an investigative agent at counsel table throughout the trial although the agent is or may be a witness. The practice is permitted as an exception to the rule of exclusion and compares with the situation defense counsel finds himself in-he always has the client with him to consult during the trial. The investigative agent's presence may be extremely important to government counsel, especially when the case is complex or involves some specialized subject matter. The agent, too, having lived with the case for a long time, may be able to assist in meeting trial surprises where the best-prepared counsel would otherwise have difficulty. Yet, it would not seem the Government could often meet the burden under rule 615 of showing that the agent's presence is essential. Furthermore, it could be dangerous to use the agent as a witness as early in the case as possible, so that he might then help counsel as a nonwitness, since the agent's testimony could be needed in rebuttal. Using another, nonwitness agent from the same investigative agency would not generally meet government counsel's needs. This problem is solved if it is clear that investigative agents are within the group specified under the second exception made in the rule, for "an officer or employ. ee of a party which is not a natural person designated as its representative by its attorney." It is our understanding that this was the intention of the House committee. It is certainly this committee's construction of the rule.

ARTICLE VII. OPINIONS AND EXPERT TESTIMONY

Rule 701. Opinion Testimony by Lay Witnesses

If the witness is not testifying as an expert, his testimony in the form of opinions or inferences is limited to those opinions or inferences which are (a) rationally based on the perception of the witness and (b) helpful to a clear understanding of his testimony or the determination of a fact in issue.

(Pub. L. 93-595, § 1, Jan. 2, 1975, 88 Stat. 1937.)

Notes of Advisory Committee on Proposed Rules

The rule retains the traditional objective of putting the trier of fact in possession of an accurate reproduction of the event.

Limitation (a) is the familiar requirement of firsthand knowledge or observation.

Limitation (b) is phrased in terms of requiring testimony to be helpful in resolving issues. Witnesses often find difficulty in expressing themselves in language which is not that of an opinion or conclusion. While the courts have made concessions in certain recurring situations, necessity as a standard for permitting opinions and conclusions has proved too elusive and too unadaptable to particular situations for purposes of satisfactory judicial administration. McCormick § 11. Moreover, the practical impossibility of determinating by rule what is a "fact," demonstrated by a century of litigation of the question of what is a fact for purposes of pleading under the Field Code, extends into evidence also. 7 Wigmore § 1919. The rule assumes that the natural characteristics of the adversary system will generally lead to an acceptable result, since the detailed account carries more conviction than the broad assertion, and a lawyer can be expected to display his witness to the best advantage. If he fails to do so, cross-examination and argument will point up the weakness. See Ladd, Expert Testimony, 5 Vand.L.Rev. 414, 415-417 (1952). If, despite these considerations, attempts are made to introduce meaningless assertions which amount to little more than choosing up sides, exclusion for lack of helpfulness is called for by the rule.

The language of the rule is substantially that of Uniform. Rule 56(1). Similar provisions are California Evidence Code § 800; Kansas Code of Civil Procedure § 60-456(a); New Jersey Evidence Rule 56(1).

Rule 702. Testimony by Experts

If scientific, technical, or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training, or education, may testify thereto in the form of an opinion or otherwise.

(Pub. L. 93-595, § 1, Jan. 2, 1975, 88 Stat. 1937.) NOTES OF ADVISORY COMMITTEE ON PROPOSED RULES

An intelligent evaluation of facts is often difficult or impossible without the application of some scientific, technical, or other specialized knowledge. The most common source of this knowledge is the expert witness, although there are other techniques for supplying it.

Most of the literature assumes that experts testify only in the form of opinions. The assumption is logically unfounded. The rule accordingly recognizes that an expert on the stand may give a dissertation or exposition of scientific or other principles relevant to the case, leaving the trier of fact to apply them to the facts. Since much of the criticism of expert testimony has centered upon the hypothetical question, it seems wise to recognize that opinions are not indispensable and to encourage the use of expert testimony in nonopinion form when counsel believes the trier can itself draw the requisite inference. The use of opinions is not abolished by the rule, however. It will continue to be permissible for the experts to take the further step of suggesting the inference which should be drawn from applying the specialized knowledge to the facts. See Rules 703 to 705.

Whether the situation is a proper one for the use of expert testimony is to be determined on the basis of assisting the trier. "There is no more certain test for determining when experts may be used than the common sense inquiry whether the untrained layman would be qualified to determine intelligently and to

the best possible degree the particular issue without enlightenment from those having a specialized understanding of the subject involved in the dispute." Ladd, Expert Testimony, 5 Vand.L.Rev. 414, 418 (1952). When opinions are excluded, it is because they are unhelpful and therefore superfluous and a waste of time. 7 Wigmore § 1918.

The rule is broadly phrased. The fields of knowledge which may be drawn upon are not limited merely to the "scientific" and "technical" but extend to all "specialized" knowledge. Similarly, the expert is viewed, not in a narrow sense, but as a person qualified by "knowledge, skill, experience, training or education." Thus within the scope of the rule are not only experts in the strictest sense of the word, e.g., physicians, physicists, and architects, but also the large group sometimes called "skilled" witnesses, such as bankers or landowners testifying to land values.

Rule 703. Bases of Opinion Testimony by Experts

The facts or data in the particular case upon which an expert bases an opinion or inference may be those perceived by or made known to him at or before the hearing. If of a type reasonably relied upon by experts in the particular field in forming opinions or inferences upon the subject, the facts or data need not be admissible in evidence.

(Pub. L. 93-595, § 1, Jan. 2, 1975, 88 Stat. 1937.)

NOTES OF ADVISORY COMMITTEE on PROPOSED RULES

Facts or data upon which expert opinions are based may, under the rule, be derived from three possible sources. The first is the firsthand observation of the witness, with opinions based thereon traditionally allowed. A treating physician affords an example. Rheingold, The Basis of Medical Testimony, 15 Vand.L.Rev. 473, 489 (1962). Whether he must first relate his observations is treated in Rule 705. The second source, presentation at the trial, also reflects existing practice. The technique may be the familiar hypothetical question or having the expert attend the trial and hear the testimony establishing the facts. Problems of determining what testimony the expert relied upon, when the latter technique is employed and the testimony is in conflict, may be resolved by resort to Rule 705. The third source contemplated by the rule consists of presentation of data to the expert outside of court and other than by his own perception. In this respect the rule is designed to broaden the basis for expert opinions beyond that current in many jurisdictions and to bring the judicial practice into line with the practice of the experts themselves when not in court. Thus a physician in his own practice bases his diagnosis on information from numerous sources and of considerable variety, including statements by patients and relatives, reports and opinions from nurses, technicians and other doctors, hospital records, and X rays. Most of them are admissible in evidence, but only with the expenditure of substantial time in producing and examining various authenticating witnesses. The physician makes life-and-death decisions in reliance upon them. His validation, expertly performed and subject to cross-examination, ought to suffice for judicial purposes. Rheingold, supra, at 531; McCormick § 15. A similar provision is California Evidence Code § 801(b).

The rule also offers a more satisfactory basis for ruling upon the admissibility of public opinion poll evidence. Attention is directed to the validity of the techniques employed rather than to relatively fruitless inquiries whether hearsay is involved. See Judge Feinberg's careful analysis in Zippo Mfg. Co. v. Rogers Imports, Inc., 216 F.Supp. 670 (S.D.N.Y. 1963) See also Blum et al, The Art of Opinion Research: A Lawyer's Appraisal of an Emerging Service, 24 U.Chi.L.Rev. 1

(1956); Bonynge, Trademark Surveys and Techniques and Their Use in Litigation, 48 A.B.A.J. 329 (1962); Zeisel, The Uniqueness of Survey Evidence, 45 Cornell L.Q. 322 (1960); Annot., 76 A.L.R.2d 919.

If it be feared that enlargement of permissible data may tend to break down the rules of exclusion unduly, notice should be taken that the rule requires that the facts or data "be of a type reasonably relied upon by experts in the particular field." The language would not warrant admitting in evidence the opinion of an "accidentologist" as to the point of impact in an automobile collision based on statements of bystanders, since this requirement is not satisfied. See Comment, Cal.Law Rev. Comm'n, Recommendation Proposing an Evidence Code 148-150 (1965).

Rule 704. Opinion on Ultimate Issue

Testimony in the form of an opinion or inference otherwise admissible is not objectionable because it embraces an ultimate issue to be decided by the trier of fact.

(Pub. L. 93-595, § 1, Jan. 2, 1975, 88 Stat. 1937.) NOTES OF ADVISORY COMMITTEE ON PROPOSED RULES

The basic approach to opinions, lay and expert, in these rules is to admit them when helpful to the trier of fact. In order to render this approach fully effective and to allay any doubt on the subject, the so-called "ultimate issue" rule is specifically abolished by the instant rule.

The older cases often contained strictures against allowing witnesses to express opinions upon ultimate issues, as a particular aspect of the rule against opinions. The rule was unduly restrictive, difficult of application, and generally served only to deprive the trier of fact of useful information. 7 Wigmore §§ 1920, 1921; McCormick § 12. The basis usually assigned for the rule, to prevent the witness from "usurping the province of the jury," is aptly characterized as "empty rhetoric." 7 Wigmore § 1920, p. 17. Efforts to meet the felt needs of particular situations led to odd verbal circumlocutions which were said not to violate the rule. Thus a witness could express his estimate of the criminal responsibility of an accused in terms of sanity or insanity, but not in terms of ability to tell right from wrong or other more modern standard. And in cases of medical causation, witnesses were sometimes required to couch their opinions in cautious phrases of "might or could," rather than "did," though the result was to deprive many opinions of the positiveness to which they were entitled, accompanied by the hazard of a ruling of insufficiency to support a verdict. In other instances the rule was simply disregarded, and, as concessions to need, opinions were allowed upon such matters as intoxication, speed, handwriting, and value, although more precise coincidence with an ultimate issue would scarcely be possible.

Many modern decisions illustrate the trend to abandon the rule completely. People v. Wilson, 25 Cal.2d 341, 153 P.2d 720 (1944), whether abortion necessary to save life of patient; Clifford-Jacobs Forging Co. v. Industrial Comm., 19 Ill.2d 236, 166 N.E.2d 582 (1960), medical causation; Dowling v. L. H. Shattuck, Inc., 91 N.H. 234, 17 A.2d 529 (1941), proper method of shoring ditch; Schweiger v. Solbeck, 191 Or. 454, 230 P.2d 195 (1951), cause of landslide. In each instance the opinion was allowed.

The abolition of the ultimate issue rule does not lower the bars so as to admit all opinions. Under Rules 701 and 702, opinions must be helpful to the trier of fact, and Rule 403 provides for exclusion of evidence which wastes time. These provisions afford ample assurances against the admission of opinions which would merely tell the jury what result to reach, somewhat in the manner of the oath-helpers of an earlier day. They also stand ready to exclude opinions phrased in terms of inadequately explored legal criteria. Thus the question, "Did T have capacity to make a

the parties, and may appoint expert witnesses of its own selection. An expert witness shall not be appointed by the court unless he consents to act. A witness so appointed shall be informed of his duties by the court in writing, a copy of which shall be filed with the clerk, or at a conference in which the parties shall have opportunity to participate. A witness so appointed shall advise the parties of his findings, if any; his deposition may be taken by any party; and he may be called to testify by the court or any party. He shall be subject to cross-examination by each party, including a party calling him as a witness.

(b) Compensation.—Expert witnesses so appointed are entitled to reasonable compensation in whatever sum the court may allow. The compensation thus fixed is payable from funds which may be provided by law in criminal cases and civil actions and proceedings involving just compensation under the fifth amendment. In other civil actions and proceedings the compensation shall be paid by the parties in such proportion and at such time as the court directs, and thereafter charged in like manner as other costs.

(c) Disclosure of appointment.-In the exercise of its discretion, the court may authorize disclosure to the jury of the fact that the court appointed the expert witness.

(d) Parties' experts of own selection.-Nothing in this rule limits the parties in calling expert witnesses of their own selection. (Pub. L. 93-595, § 1, Jan. 2, 1975, 88 Stat. 1938.) NOTES OF ADVISORY COMMITTEE ON PROPOSED RULES The practice of shopping for experts, the venality of some experts, and the reluctance of many reputable experts to involve themselves in litigation, have been matters of deep concern. Though the contention is made that court appointed experts acquire an aura of infallibility to which they are not entitled. Levy, Impartial Medical Testimony-Revisited, 34 Temple L.Q. 416 (11961), the trend is increasingly to provide for their use. While experience indicates that actual appointment is a relatively infrequent occurrence, the assumption may be made that the availability of the procedure in itself decreases the need for resorting to it. The ever-present possibility that the judge may appoint an expert in a given case must inevitably exert a sobering effect on the expert witness of a party and upon the person utilizing his services.

The inherent power of a trial judge to appoint an expert of his own choosing is virtually unquestioned. Scott v. Spanjer Bros., Inc., 298 F.2d 928 (2d Cir. 1962); Danville Tobacco Assn. v. Bryant-Buckner Associates, Inc., 333 F.2d 202 (4th Cir. 1964); Sink, The Unused Power of a Federal Judge to Call His Own Expert Witnesses, 29 S.Cal.L.Rev. 195 (1956); 2 Wigmore § 563, 9 Id. § 2484; Annot., 95 A.L.R.2d 383. Hence the problem becomes largely one of detail.

The New York plan is well known and is described in Report by Special Committee of the Association of the Bar of the City of New York: Impartial Medical Testimony (1956). On recommendation of the Section of Judicial Administration, local adoption of an impartial medical plan was endorsed by the American Bar Association. 82 A.B.A.Rep. 184-185 (1957). Descriptions and analyses of plans in effect in various parts of the country are found in Van Dusen, A United States District Judge's View of the Impartial Medical Expert System, 322 F.R.D. 498 (1963); Wick and Kightlinger, Impartial Medical Testimony Under the Federal Civil Rules: A Tale of Three Doctors, 34 Ins. Counsel J. 115 (1967); and numerous articles collected in Klein, Judicial Ad

ministration and the Legal Profession 393 (1963). Statutes and rules include California Evidence Code §§ 730-733; Illinois Supreme Court Rule 215(d), Ill.Rev.Stat. 1969, c. 110A, § 215(d); Burns Indiana Stats. 1956, § 9-1702; Wisconsin Stats. Annot.1958, § 957.27.

In the federal practice, a comprehensive scheme for court appointed experts was initiated with the adoption of Rule 28 of the Federal Rules of Criminal Procedure in 1946. The Judicial Conference of the United States in 1953 considered court appointed experts in civil cases, but only with respect to whether they should be compensated from public funds, a proposal which was rejected. Report of the Judicial Conference of the United States 23 (1953). The present rule expands the practice to include civil cases.

Subdivision (a) is based on Rule 28 of the Federal Rules of Criminal Procedure, with a few changes, mainly in the interest of clarity. Language has been added to provide specifically for the appointment either on motion of a party or on the judge's own motion. A provision subjecting the court appointed expert to deposition procedures has been incorporated. The rule has been revised to make definite the right of any party, including the party calling him, to cross-examine.

Subdivision (b) combines the present provision for compensation in criminal cases with what seems to be a fair and feasible handling of civil cases, originally found in the Model Act and carried from there into Uniform Rule 60. See also California Evidence Code §§ 730-731. The special provision for Fifth Amendment compensation cases is designed to guard against reducing constitutionally guaranteed just compensation by requiring the recipient to pay costs. See Rule 71A(Z) of the Rules of Civil Procedure.

Subdivision (c) seems to be essential if the use of court appointed experts is to be fully effective. Uniform Rule 61 so provides.

Subdivision (d) is in essence the last sentence of Rule 28(a) of the Federal Rules of Criminal Procedure.

ARTICLE VIII. HEARSAY

NOTES OF ADVISORY COMmittee on PROPOSED RULES

INTRODUCTORY NOTE: THE HEARSAY PROBLEM

The factors to be considered in evaluating the testimony of a witness are perception, memory, and narration. Morgan, Hearsay Dangers and the Application of the Hearsay Concept, 62 Harv.L.Rev. 177 (1948), Selected Writings on Evidence and Trial 764, 765 (Fryer ed. 1957); Shientag, Cross-Examination-A Judge's Viewpoint, 3 Record 12 (1948); Strahorn, A Reconsideration of the Hearsay Rule and Admissions, 85 U.Pa.L.Rev. 484, 485 (1937), Selected Writings, supra, 756, 757: Weinstein, Probative Force of Hearsay, 46 Iowa L.Rev. 331 (1961). Sometimes a fourth is added, sincerity, but in fact it seems merely to be an aspect of the three already mentioned.

In order to encourage the witness to do his best with respect to each of these factors, and to expose any inaccuracies which may enter in, the Anglo-American tradition has evolved three conditions under which witnesses will ideally be required to testify: (1) under oath, (2) in the personal presence of the trier of fact, (3) subject to cross-examination.

(1) Standard procedure calls for the swearing of witnesses. While the practice is perhaps less effective than in an earlier time, no disposition to relax the requirement is apparent, other than to allow affirmation by persons with scruples against taking oaths.

(2) The demeanor of the witness traditionally has been believed to furnish trier and opponent with valuable clues. Universal Camera Corp. v. N.L.R.B., 340 U.S. 474, 495-496, 71 S.Ct. 456, 95 L.Ed. 456 (1951); Sahm, Demeanor Evidence: Elusive and Intangible Imponderables, 47 A.B.A.J. 580 (1961), quoting numerous

large part of the area presently occupied by the hearsay rule in the event of the abolition of the latter. The resultant split between civil and criminal evidence is regarded as an undesirable development.

(2) Abandonment of the system of class exceptions in favor of individual treatment in the setting of the particular case, accompanied by procedural safeguards, has been impressively advocated. Weinstein, The Probative Force of Hearsay, 46 Iowa L.Rev. 331 (1961). Admissibility would be determined by weighing the probative force of the evidence against the possibility of prejudice, waste of time, and the availability of more satisfactory evidence. The bases of the traditional hearsay exceptions would be helpful in assessing probative force. Ladd, The Relationship of the Principles of Exclusionary Rules of Evidence to the Problem of Proof, 18 Minn.L.Rev. 506 (1934). Procedural safeguards would consist of notice of intention to use hearsay, free comment by the judge on the weight of the evidence, and a greater measure of authority in both trial and appellate judges to deal with evidence on the basis of weight. The Advisory Committee has rejected this approach to hearsay as involving too great a measure of judicial discretion, minimizing the predictability of rulings, enhancing the difficulties of preparation for trial, adding a further element to the already over-complicated congeries of pretrial procedures, and requiring substantially different rules for civil and criminal cases. The only way in which the probative force of hearsay differs from the probative force of other testimony is in the absence of oath, demeanor, and cross-examination as aids in determining credibility. For a judge to exclude evidence because he does not believe it has been described as "altogether atypical, extraordinary. • " Chadbourn, Bentham and the Hearsay Rule-A Benthamic View of Rule 63(4)(c) of the Uniform Rules of Evidence, 75 Harv.L.Rev. 932, 947 (1962).

(3) The approach to hearsay in these rules is that of the common law, i.e., a general rule excluding hearsay, with exceptions under which evidence is not required to be excluded even though hearsay. The traditional hearsay exceptions are drawn upon for the exceptions, collected under two rules, one dealing with situations where availability of the declarant is regarded as immaterial and the other with those where unavailability is made a condition to the admission of the hearsay statement. Each of the two rules concludes with a provision for hearsay statements not within one of the specified exceptions "but having comparable circumstantial guarantees of trustworthiness." Rules 803(24) and 804(b)(6). This plan is submitted as calculated to encourage growth and development in this area of the law, while conserving the values and experience of the past as a guide to the future.

CONFRONTATION AND DUE PROCESS

Until very recently, decisions invoking the confrontation clause of the Sixth Amendment were surprisingly few, a fact probably explainable by the former inapplicability of the clause to the states and by the hearsay rule's occupancy of much the same ground. The pattern which emerges from the earlier cases invoking the clause is substantially that of the hearsay rule, applied to criminal cases: an accused is entitled to have the witnesses against him testify under oath, in the presence of himself and trier, subject to cross-examination; yet considerations of public policy and necessity require the recognition of such exceptions as dying declarations and former testimony of unavailable witnesses. Mattor v. United States, 156 U.S. 237, 15 S.Ct. 337, 39 L.Ed. 409 (1895); Motes v. United States, 178 U.S. 458, 20 S.Ct. 993, 44 L.Ed. 1150 (1900); Delaney v. United States, 263 U.S. 586, 44 S.Ct. 206, 68 L.Ed. 462 (1924). Beginning with Snyder v. Massachusetts, 291 U.S. 97, 54 S.Ct. 330, 78 L.Ed. 674 (1934), the Court began to speak of confrontation as an aspect of procedural due process, thus extending its applicability to state cases and to federal cases other than crimi
