Opinion
TOBRINER, J.Defendant John Irwin Crowe appeals from a conviction, following jury verdict, of assault by means of force likely to produce great bodily harm (Pen. Code, § 245, subd. (a)) and robbery (Pen. Code, § 211). The jury determined the robbery to be of the second degree. (Pen. Code, § 211a.)
The principal issue of the case turns on defendant’s contention that the trial court’s conduct of the voir dire violated Penal Code section 1078. Voir dire does, indeed, often entail a protracted undertaking by counsel that is designed for tactical advantage rather than for the elimination of an undesirable juror. To avoid such misuse, the trial court itself in the instant case examined the jurors with the assistance of written questions submitted by counsel. We shall explain that section 1078 permits this method of examina*819tion; counsel, instead of directly questioning the prospective juror, submits to the court questions, which, if found within the scope of reasonable examination, can be propounded by the court to the jurors.
In approving such procedure we point out that voir dire, designed as a device to weed out unsuitable jurors, may, if over-extended by counsel, be self-destructive. If voir dire is burdened with the weight of excess rococo examination, the trial structure itself can be endangered. We believe that section 1078 permits the voir dire to be left to the discretion of the trial judge, who among other methods, can put the questions to the jurors, aided by counsel.
We likewise reject defendant’s contentions that the court prejudicially erred in refusing to put to the jurors certain additional questions requested by defense counsel, that defendant was denied his right to 10 peremptory challenges, and that the evidence was insufficient to support the verdict. Finding no prejudicial error, we affirm the defendant’s conviction.
1. In undertaking the entire examination of prospective jurors itself, assisted by questions submitted by counsel, the trial court did not deny counsel for defendant his right to reasonable examination of jurors as provided in Penal Code section 1078.
Penal Code section 1078 states that “It shall be the duty of the trial court to examine the prospective jurors to select a fair and impartial jury. He shall permit reasonable examination of prospective jurors by counsel for the people and for the defendant.” The issue before us is whether the procedure employed by the trial court in the voir dire of the jury in the present case comports with the requirements of section 1078.
We summarize the manner in which the court conducted the voir dire. Prior to trial the court notified counsel that it would not permit direct voir dire by counsel. Defense counsel then submitted to the court a written list of twelve general and six individual questions delineating the subject matter that he wished to be covered on voir dire. The court tentatively seated 12 jurors, explained the nature of the case, and advised the jurors that the court bore the duty to examine them to select a fair and impartial panel. After giving general instructions on the presumption of innocence and reasonable doubt, the court introduced defendant and both counsel, and stated the names of prospective witnesses. The jurors indicated that they were not acquainted with defendant, counsel, or the witnesses. After describing generally the duties and functions of the jurors, the court examined each juror as to his jury experience, ability to follow the law, racial prejudice, general area of residence, occupation, marital and family status, and relationships to law enforcement agencies. The judge asked each juror whether he had been *820charged with committing an assault or robbery or had been a victim of such an offense. The court then inquired into the consequences to the juror from involvement in a lengthy trial; finally, the court asked each juror generally whether that juror knew of any reason why he could not be fair and impartial.
After concluding this examination, the court asked counsel to approach the bench, and the following colloquy occurred:
“The Court: All right, now, are there any other questions you want the Court to ask the jurors?
“Mr. Fiore [defense counsel]: Your Honor, I would like to have the opportunity to ask some questions myself. I am accorded that right under section 1078 of the Penal Code.
“The Court: What questions do you want to ask?
“Mr. Fiore: I wanted to ask the young lady, Mrs. Meals, if the fact that she is a Negro and the only one on the panel if that might in any way place her in a compromising position if she were to be chosen to remain as a juror.
“I also want to delve a little further into the nature of the occupation of the husbands of three other jurors; namely, Mrs. Rotman, Mrs. Klobucar and Mrs. Hupp.
“I also want to ask some other general questions of all of the jury panel relative to—•
“The Court: State them.
“Mr. Fiore: The fact that my client is in custody presently, if that would have any effect; that is, if they would consider that he is more likely to be guilty than innocent because he is in custody.
“I want to ask if they all understand the fact that he is in custody because he cannot afford bail.
“I also want to ask specific questions of individual jurors as to whether or not they have partitiipated in a situation where they were asked to identify any individual. In other words, if they were ever asked, as an eye witness, to make an identification; if they believed that an individual can be mistaken in an identification, and questions relative to the identification of individuals.
“These would be substantially the questions I would like to ask personally. Depending upon their answers there may be others.
“The Court: All right. Mrs. Meals answered that the question I asked *821of Mrs. Day, concerning whether or not there were any prejudice for or against the defendant by reason of his color.
“Your motion is denied."
The court then permitted counsel to exercise peremptory challenges. After the dismissal of each challenged juror, the court questioned his replacement in the same fashion as it had questioned the original 12. Following the completion of the jury selection defense counsel again argued that the procedure employed by the court denied defendant the rights accorded him under Penal Code section 1078.
We begin our analysis of defendant's argument with an account of the history of jury voir dire in California, and of the enactment and interpretation of Penal Code section 1078. This history, we believe, will demonstrate that although section 1078 confers upon counsel a right to reasonable examination of jurors, neither that section, nor any of the cases construing it, require that such examination be conducted directly by counsel without the intervening supervision of the trial judge. To the contrary, the cases construing section 1078 illustrate that the court will uphold any method of voir dire which results in reasonable examination of prospective jurors, submission of proposed questions by counsel to the court which, after eliminating improper or duplicative queries, itself interrogates the prospective jurors.
The right of counsel to examine a prospective juror before challenge was established by court decision in 1855.1 (People v. Backus (1855) 5 Cal. 275.) Many years later, however, in People v. Edwards (1912) 163 Cal. 752, 753 [127 P. 58], the court observed that “The records of the cases appealed to this court in which rulings made while impaneling a jury have been involved, indicate that there is an increasing tendency to prolong the proceedings inordinately by allowing counsel on either side to indulge in tedious examination of jurors, apparently with no definite purpose or object in view, but with the hope of eliciting something indicating the advisability of a peremptory challenge, and that the supposed privilege of doing this has been greatly abused.” In the hope of cúrbing this abuse Edwards overruled past decisions and held that counsel could not voir dire a juror as to matters immaterial to a challenge for cause.2
*822Despite the Edwards decision, the problem of lengthy and inordinate voir dire continued, and in 1927 the Commission for the Reform of Criminal Procedure in California recommended the enactment of a statute to govern the procedure. This proposed statute was to read as follows: “It shall be the duty of the trial court to examine the prospective jurors and to select a fair and impartial jury. He may, in his discretion, permit reasonable examination of prospective jurors by counsel for the people and for the defendant.”* *3 (Italics added.) The Legislature, however, rejected the commission’s proposal to place voir dire entirely in the discretion of the trial court, and instead enacted the present section 1078,4 which in the second sentence, changed the word “may” to “shall” and eliminated “in his discretion.” As we have noted the statute now reads: “It shall be the duty of the trial court to examine the prospective jurors to select a fair and impartial jury. He shall permit reasonable examination of prospective jurors by counsel for the people and for the defendant.” (Italics added.)
Shortly after the enactment of section 1078, this court decided several cases construing that section. Both parties rely upon these cases: defendant asserts that the decisions establish his absolute right to direct examination by counsel; the Attorney General maintains that they show that the provision is not mandatory but permissive and that the court may refuse any oral examination by counsel. Even assuming it is mandatory, however, the Attorney General argues that reasonable examination by counsel, does not mean that such “reasonable examination” must be orally conducted directly by counsel.
In the first case urged in support of defendant’s position that reached this court, People v. Coen (1928) 205 Cal. 596 [271 P. 1074], the trial judge himself questioned each juror. Defense counsel asked that juror Smith be queried as to whether he had read various newspaper accounts of the case; the judge refused to permit the question. The Supreme Court held that the judge erroneously restricted the examination of juror Smith, but found the error not prejudicial because the judge had examined all other jurors on newspaper publicity, and defendant did not excuse Smith by peremptory challenge.
Defendant relies primarily upon two subsequent cases, People v. Estorga *823(1928) 206 Cal. 81 (273 P. 575] and People v. Barrett (1929) 207 Cal. 47 [276 P. 1003]. In Estorga the trial judge questioned the jury panel collectively, inquiring into whether they harbored prejudice and taking the panel’s silence as a negative reply. When defense counsel requested permission to inquire into the individual backgrounds of the jurors, the judge refused. Holding this refusal erroneous, the Supreme Court set out to explain the purpose of the 1927 enactment; “We have noted a tendency on the part of trial judges throughout the state to place too literal an interpretation upon what is the 'duty of the trial court to examine prospective jurors,’ and to pay too little attention to the right of a ‘reasonable examination of prospective jurors by counsel’ for the People and, particularly, counsel for the defendant. . . . The purpose of the statute, however, was not to bring about expedition by depriving either the People, or defendants charged with the commission of offenses, of the right of a reasonable examination of prospective jurors, and the Legislature was particular to provide for that right.” (206 Cal. at p. 84.) Nevertheless, in Estorga, the overwhelming evidence of defendant’s guilt led the court to hold the error nonprejudicial.
In People v. Barrett (1929) 207 Cal. 47 [276 P. 1003], the court again condemned the practice of collective examination of the jury panel, and this time the close balance in the evidence led to a finding of prejudicial error. Finally, in People v. Ranney (1931) 213 Cal. 70 [1 P.2d 423], the court found reversible error when a trial judge refused to permit counsel to inquire of a juror whether he would be prejudiced against defendant because of defendant’s prior convictions.
To counter the cases cited by defendant, the Attorney General relies, among other decisions, upon People v. Brown (1929) 207 Cal. 172, 178 [277 P. 320]. In Brown, the trial judge, following the common law procedure of permitting examination of a juror only after a challenge for cause, conducted the interrogation himself but permitted counsel to suggest questions; whenever a challenge for cause was interposed and denied, the challenging attorney was allowed to conduct the voir dire of the challenged juror. We held that “(t]his method of examining jurors has been provided for by the recent statute, section 1078 of the Penal Code . . . and where fairly conducted has been approved by this court.” (207 Cal. at p. 178.) People v. Lazarus (1929) 207 Cal. 507, 511-512 [279 P. 145], also supports the right of the trial court to voir dire the jurors before entertaining questions from counsel.
This review of the legislative history of section 1078, and of the cases interpreting it, confirms the fact that the section confers a right to reasonable examination of prospective jurors; denial of this right has been held to be *824error in People v. Coen (1928) 205 Cal. 596 [271 P. 1074]; People v. Estorga (1928) 206 Cal. 81 [273 P. 575]; People v. Barrett (1929) 207 Cal. 47 [276 P. 1003], and People v. Ranney (1931) 213 Cal. 70 [1 P.2d 423]. We must therefore reject the Attorney General’s contention that the second sentence of section 1078, which states that the court “shall” permit reasonable examination of jurors by counsel, does not require the court to conduct a reasonable examination of prospective jurors by counsel. The mandate, however, directs the court to “permit a reasonable examination” by counsel. A reasonable examination can embrace a procedure by which counsel submits questions to the judge who, in turn, renders them to the prospective juror. Nothing in the legislative history of section 1078 or in the cases interpreting it compels the conclusion that direct questioning by counsel is essential to comply with the mandate of section 1078; we note that three decisions, People v. Coen (1928) 205 Cal. 596, 605 [271 P. 1074] (by implication), People v. Brown (1929) 207 Cal. 172 [277 P. 320], and People v. Lazarus (1929) 207 Cal. 507 [279 P. 145], approved methods of voir dire in which the trial court, utilizing questions suggested by counsel, undertook the principal examination of jurors itself, relegating direct examination by counsel to a secondary role.
Subsequent cases have upheld the right of counsel to a reasonable examination of prospective jurors, placing limits upon the purpose and content of counsel’s inquiry. Rousseau v. West Coast House Movers (1967) 256 Cal.App.2d 878, 882 [64 Cal.Rptr. 655], sets out the limits on the scope of voir dire: “Such examination is not for the purpose of determining the exercise of peremptory challenges. . . . Neither is it a function of the examination of prospective jurors to educate the jury panel to the particular facts of the case, to compel the jurors to commit themselves to vote a particular way, to prejudice the jury for or against a particular party, to argue the case, to indoctrinate the jury, or to instruct the jury in matters of law.”5 On the other hand, if counsel’s proposed question is reasonable and falls within these limits, it is error for the trial court to refuse to allow that question to be put to the juror. (See People v. Terry (1964) 61 Cal.2d 137, 147 [37 Cal.Rptr. 605, 390 P.2d 381]; People v. Boorman (1965) 142 Cal.App.2d 85, 89-90 [297 P.2d 741]; People v. Love (1960) 53 Cal.2d 843, 852, fn. 1 [3 Cal.Rptr. 665, 350 P.2d 705] (dictum).)
We find no statutory prohibition of a procedure, such as that followed *825in this case, which channels voir dire examination through the trial judge. We approve this method of curtailing the inordinate time consumed in the process of the selection of jurors.6 Thus appellate cases have referred to “the waste of valuable court time involved” (Sweet v. Stutch (1966) 240 Cal.App.2d 891, 894 [50 Cal.Rptr. 9]) and to the “tedious, irksome and time-wasting prolongation of individual questioning of individual jurors by one side and then the other" (People v. Parker (1965) 235 Cal.App.2d 86, 98 [44 Cal.Rptr. 900].) In People v. Adams (1971) 21 Cal.App.3d 972, 979 [99 Cal.Rptr. 122], the court observed that “It is commonplace knowledge that there have been extensive abuses by counsel on voir dire examination by engaging in tedious and time-wasting questions, which are seemingly interminable and repetitious and designed in many instances to accomplish purposes other than the legitimate objects of a reasonable voir dire examination.”
As People v. Adams observed, the problem of undue consumption of time conjoins with the problem of abuse of voir dire by counsel seeking a tactical advantage.7 Maxwell, The Case of the Rebellious Juror (1970) 56 A.B.A.J. 838, 841-842, summarizes the vice of using the voir dire as a ploy to gain tactical advantage: “The average trial manual bows in passing to the use of voir dire in obtaining a jury that is fair to both sides. Then it emphasizes that its greatest use is, in the words of the notorious Irish comic, Mr. Dooley, to get a jury that is ‘more fair to wan side than the other.’ Advice to the neophyte abounds in strategems by which he may prejudice the jurors in favor of himself, his client and his case before the actual trial has started. Every field of human endeavor from psychiatry to animal magnetism and phrenology is to be used in observing the juror as the lengthy questioning proceeds. Thus, rapport can be established. If not, a challenge for cause, if possible; or more likely a peremptory based on intuition.’’8
*826The procedure which we sanction in the instant case coincides with the federal method now followed. This federal method dates from the recommendation, in 1924, of the Judicial Conference of Senior Circuit Judges: “Examination of the prospective jurors shall be by the judge alone. If counsel on either side desires that additional matter be inquired into, he shall state the matter to the judge, and the judge, if the matter is proper, shall conduct the examination.” In 1928 the Second Circuit upheld the constitutionality of this method of voir dire, Justice Learned Hand writing that “while it was the custom at common law to allow the parties to cross-examine, there is nothing in this essential to securing a panel free from bias. The length and particularity of the examination of jurors had become a scandal, and required some effective control.” (Falter v. United States (2d Cir. 1928) 23 F.2d 420, 426.) At present, the federal rules permit the district court to determine, in its discretion, which method of voir dire it will use;9 the great majority of districts follow the practice of interrogation of jurors by the judge, permitting counsel to submit questions for use by the court.10
State courts have also moved in the direction of greater judicial control over voir dire.* 11 We note that Illinois and Michigan, states which previously permitted extensive voir dire by counsel, have adopted court rules placing upon the trial judge the primary responsibility to conduct the voir dire. (Ill.Sup.Ct. rule 234; Mich. Ct. rule 511.3.) In 1969 the New Jersey Supreme Court, after reviewing the problems of voir dire by counsel in that jurisdiction, resolved that in future cases voir dire should be “conducted exclusively by or through the trial judges to the extent reasonably possible.” State v. Manley (1969) 54 N.J. 259 [255 A.2d 193, 206, 43 A.L.R.3d 1062]; (see N.J. rule 1:8-3(a)).12
Both federal and state judges have noted the benefits derived from in*827creasing judicial participation in voir dire13 The American Bar Association’s Advisory Committee on the Criminal Trial has recommended its adoption in all jurisdictions (American Bar Association Project on Minimum Standards for Criminal Justice, Standards Relating to Trial by Jury (1968) p. 63.)14 The advantages of this method are apparent: it should significantly limit the time consumed in voir dire;15 it reduces the opportunity for counsel to misuse voir dire to influence the jurors;16 and by facilitating preliminary screening of questions by the trial court, it should aid in eliminating improper interrogatories.17 Such advantages, of course, would be of no avail if the federal system of jury selection actually resulted in unfair and biased juries, but no evidence suggests that this is the case.18
*828We conclude that direct examination by counsel has perverted the purpose of voir dire, and transformed the examination of jurors into a contest between counsel for the selection of a jury partial to his cause and for the attainment of rapport with the jurors so selected, a contest which may overshadow the actual trial on the merits.19 This transformation compels us to emphasize again the dual purpose of section 1078, which confers not only a right of counsel to reasonable examination of prospective jurors, but also a duty upon the trial court to select an impartial jury.20 In 1928 this court found it necessary to admonish trial judges that they had been placing too literal an interpretation upon the duty of the trial court, and paying too little attention to the right of counsel.21 The subsequent exploitation of the voir dire for partisan advantage has reversed the situation: it is now time to stress that counsel’s right is only to a reasonable examination of prospective jurors—reasonable in length, in method, in purpose, and in content.22
The opportunity for reasonable examination of jurors afforded by section 1078 does not formulate a right to compete in achieving jury rapport but a right to submit questions necessary to detect and eliminate unqualified jurors.23 The requirement that such questions be submitted to the trial *829judge, who puts those he finds proper to the jurors, will not crucify this right. We conclude that Penal Code section 1078 permits, among other methods,24 a procedure of voir dire in which the court examines prospective jurors and permits counsel to submit questions to the court which, if the court finds them within the scope of reasonable examination, the court itself propounds to the jurors; the court did not err in choosing to employ this method of voir dire in the present case.25
2. The trial, court did not commit prejudicial error in refusing to put to the jury the additional questions requested by defense counsel.
We turn now to defendant’s second contention. After the court completed its voir dire of the original 12 prospective jurors, defense counsel requested additional questions, but the court refused to put those inquiries to the jurors.26 Defendant contends that in so ruling the court denied his right to reasonable examination of prospective jurors. As we explain, however, we believe that defendant failed to sustain the burden of showing that the court erred in rejecting his proposed questions, or that the error, if any, was prejudicial.
Counsel first requested that Mrs. Meals,27 the only Negro on the jury panel, be asked if that fact “might in any way place her in a compromising position.” Mrs. Meals had already affirmed that she would not be prejudiced for or against defendant because of his color, and that she knew of no reason why she could not serve as an impartial juror. The court could reasonably conclude that Mrs. Meals, in essence, already made clear that her judg*830ment would not be compromised by racial considerations and that further inquiry would be superfluous.
Defendant also requested further inquiry into the occupations of the husbands of three jurors, Mrs. Rotman, Mrs. Kiobucar and Mrs. Hupp,28 but did not indicate specifically what inquiries he desired, nor how they might lead to grounds for a challenge for cause. As we said in People v. Rigney (1961) 55 Cal.2d 236, 244 [10 Cal.Rptr. 625, 359 P.2d 23]: "`It is now well settled in this state that a juror may not be examined on voir dire solely for the purpose of laying the foundation for the exercise of a peremptory challenge.' (People v. Ferlin, 203 Cal. 587, 598 [265 P. 230].) If special circumstances in the present case made defendant's questions relevant to show bias or other grounds for a challenge for cause he should have informed the court of his reasons for asking the questions."29
Defense counsel also requested that two questions be put to the entire panel: whether the jurors would consider defendant more likely to be guilty than innocent because he was in custody, and whether they understood that he was in custody because he could not afford bail. The first question was sufficiently answered by the jurors’ earlier affirmation that they understood and would apply the presumption that a defendant is innocent until proven guilty. The second question, whether defendant was in custody because he could not afford bail or for some other reason (such as violation of parole) poses a query to which the jurors could not be expected to know the answer and should not be invited to speculate. If defense counsel desired to inform them of the reason why defendant was in custody, the proper way to do so was through an instruction to the jury, not by means of voir dire.30
Finally, counsel stated that he wanted “specific questions of individual jurors as to whether or not they have participated in a situation where they were asked to identify any individual.” We can conceive that this inquiry might lead to grounds for a challenge for cause, since the case against defendant relied upon identification testimony, and the past experience of the jurors in such situations might affect their ability to maintain impartial*831ity in the present case.31 We note, however, that at trial defense counsel did not attempt to indicate to the court how his requested inquiry could lead to a challenge for cause. And on appeal counsel offers no contention that the trial court’s refusal to permit this one inquiry, standing alone, could have so prejudiced the defendant as to require reversal of the judgment. (See Cal. Const., art. VI, § 13; People v. Watson (1956) 46 Cal.2d 818, 836 [299 P.2d 243].)
3. The court’s mistake in swearing the jury before defendant had exhausted his peremptory challenges did not constitute prejudicial error.
Penal Cede section 1070 grants a defendant accused of a noncapital offense 10 peremptory challenges to prospective jurors. After the present defendant had made six peremptory challenges, the court mistakenly announed that peremptory challenges had been completed by the defense and waived by the prosecution. On request of the court the clerk then swore the jury. The court then admonished the jury and declared a 10-minute recess.
During the recess the judge discovered that defendant was entitled to four more peremptory challenges. He asked the defense counsel if he wanted to exercise further peremptory challenges; counsel replied that he would have to confer with defendant. The record then shows that defendant’s counsel left the court’s chambers, reentered a few moments later, and stated “We will make no further peremptory challenges.”
The record thus indicated that defendant was satisfied with the jury selected and did not elect to exercise his remaining peremptory challenges. Defendant maintains, however, that once a jury has been sworn the court cannot allow peremptory challenges (see People v. Young (1929) 100 *832Cal.App. 18, 20 [279 P. 824]), and thus in declining to assert such challenges he waived no right. He also contends that to exercise peremptory challenges after the jury has been sworn would have prejudiced the jury against defendant. The short answer to both arguments is that if defense counsel believed that the court had erred and by that error selected a jury unfair to defendant, he should have articulated those views at the time. The court might then have been able to fashion some means of remedying the error; if no workable remedy appeared the court could have declared a mistrial.
In People v. Bugg (1947) 79 Cal.App.2d 174 [179 P.2d 346], when defendant had exercised only nine peremptory challenges, the trial judge miscounted and ordered the jury sworn. The Court of Appeal stated: “There is no intimation in the record that defendant desired to exercise an additional peremptory challenge or would have done so if the mistake of law had not been made. There is nothing to indicate that an objectionable juror had been forced on defendant or that he was dissatisfied with the jury selected. Under such circumstances the error cannot be held to be prejudicial.” (79 Cal.App.2d at p. 176.) We find this language apposite to the present case, and conclude that the court’s premature swearing of the jury does not constitute grounds for reversal of the judgment against defendant.
4. Substantial evidence supports defendant’s conviction.
We summarize the evidence as it appears from the testimony before the trial court.
The victim George Stansbury, Jr., lived with his brother Bennie Peterson in an apartment in Los Angeles County. On October 4, 1969, George had $120 in savings in a money clip in a pocket of his blue jeans. He kept the house key on the dresser in his bedroom.
On the afternoon of October 4 defendant, a frequent visitor at the Stansbury apartment, arrived there with a Mr. Clemmons. Clemmons asked George to change a $5 bill; George, in defendant’s presence, took out the money clip and made change. Defendant left the apartment about a half hour later, but returned that evening. At various times during the evening defendant and George conversed in the bedroom, and for a few minutes defendant was alone in that room. Eventually defendant left the apartment and about 3:30 a.m. George and his brother prepared to go to sleep. George checked the back door and Bennie locked the front door. George *833removed his blue jeans with the money clip in a pocket and stuffed them under the mattress. He went to sleep in the bedroom and Bennie laid down on the living rocm couch.
Bennie testified that he was awakened by a rumbling noise coming from the bedroom, but did not investigate and soon fell asleep again. He awoke again about 6 a.m. to see defendant standing over him about two to three feet away. After one or two seconds defendant turned and walked to the kitchen. Bennie did not get up and soon returned to sleep.
About 6:15 George came out of the bedroom; his head was bruised and bleeding and his jaw was broken. George did not know what had happened, but he soon discovered that although the blue jeans were still under the mattress the money and money clip were gone. The key was also missing from the top of the dresser, and the back door was unlocked.
Later that morning defendant telephoned the apartment. According to Bennie, who answered the phone, the caller identified himself only as “Rap,” but Bennie knew this to be defendant’s nickname and recognized defendant’s voice. Defendant said he had passed by the apartment, seen a police car, and wondered what was going on. Bennie asked who was calling; defendant responded by asking why Bennie wanted to know. Bennie then handed the phone to a police officer. The record does not indicate whether there was any conversation between defendant and the officer.
Defendant denied committing the assault or robbery. He testified that he left the Stansbury apartment about 2 a.m. and arrived home at 4:30, going to bed shortly thereafter. His parents corroborated that defendant came home about 4:30 and had retired. He arose around 7 a.m. and about two hours later drove past the Stansbury apartment while going to a grocery store. Noticing the police car outside the apartment, he went to a friend’s house and phoned to inquire into what was happening.
From this summary of the record, we conclude that substantial evidence supports the verdict against defendant. It is true, as defendant points out, that his conviction rests largely on the identification of defendant as the intruder by Bennie Peterson, and that this identification might be mistaken. The issue on appeal, however, is whether substantial evidence supports the verdict, not whether that evidence demonstrates guilt beyond a reasonable doubt. (People v. Bynum (1971) 4 Cal.3d 589, 599 [94 Cal.Rptr. 241, 483 P.2d 1193]; People v. Reilly (1970) 3 Cal.3d 421, 425 [90 Cal.Rptr. 417, 475 P.2d 649].) Viewing the evidence in the light most favorable to the prosecution (People v. Mosher (1969) 1 Cal.3d 379, 395 [82 Cal.Rptr. 379, 461 P.2d 659]), and resolving all controversy as to *834the credibility to be accorded Bennie’s testimony in favor of the verdict (see People v. Lyons (1956) 47 Cal.2d 311, 319-320 [303 P.2d 329]), we conclude that the evidence suffices to support the verdict.
The judgment is affirmed.
Wright, C. J., McComb, J., Burke, J., and Sullivan, J., concurred.
At common law, voir dire of a prospective juror was permitted only after interposition of a challenge for cause. (R. Miller, Civil Procedure of the Trial Court in Historical Perspective (1952) pp. 289-291.) In Britain and Canada, where such a restriction is still the rule, it is very unusual for an attorney to voir dire a juror. (Id. at p. 289.)

In about 25 states the trial judge has the sole or primary responsibility for voir dire of prospective jurors. For a listing of the various statutes, rules of court, and judicial decisions see Comment (1967) 11 St. Louis U.L.J. 234, 237-238. Since 1967 California has adopted rules 228 and 516, which permit use of the federal method of voir dire in civil cases (see note 14, infra) and New Jersey had adopted the federal practice in all cases (N.J. rule 1:8-3(a)).
For discussion of the beneficial effects of this method of voir dire in the federal courts, see Report of the Judicial Conference Committee on the Operation of the Jury System, The Jury System in The Federal Courts (1960) 26 F.R.D. 411, 465-468; Goodman, Should California Adopt Federal Civil Procedure (1952) 40 Cal.L.Rev. 184, 189; see also Crebs, Voir Dire Examination of Jurors: An Appraisal by a Judge, 1963 Ill.L.Forum 644, 645-646 [Ill.]; Murphy, The Selection of the Jury: Voir Dire Examination (1968) 44 F.R.D. 271, 275 [Mass.]; Note (1970) 2 Rutgers-Camden L.J. 161, 181 [N.J.].
We note that California Rules of Court, rules 228 and 516 which govern civil jury trials, were amended effective January 1, 1972, to read as follows: “In civil jury trials, the trial judge shall examine the prospective jurors to select a fair and impartial jury. He shall permit counsel for each party to submit additional questions which he shall put to the jurors as he deems proper, or for good cause, he may permit counsel to supplement the examination within limits prescribed by him. . . .” The Select Committee on Trial Court Delay has recommended amending section 1078 to conform to the language of rules 228 and 516.

All studies and discussions of the federal system of voir dire that we have examined approve that system as serving to secure a fair jury without excessive expenditure of time.

Chief Justice Burger commented at the National Conference on the Judiciary at Williamsburg, Virginia, on March 12, 1971, that selecting a jury has “become in itself a major piece of litigation consuming days or weeks.” (L.A. Times, March 13, 1971, § 7, at p. 17, col. 1.)

“. . . [I]t is not only the privilege but it is also the duty of the court to restrict the examination of jurors within reasonable bounds so as to expedite the trial.” (People v. Semone (1934) 140 Cal.App. 318, 326 [35 P.2d 379]; see People v. Adams (1971) 21 Cal.App.3d 972, 979 [99 Cal.Rptr. 122]; People v. Parker (1965) 235 Cal.App.2d 86, 98-99 [44 Cal.Rptr. 900]; People v.

“. . . [Examination may be oral or written, direct or indirect. For example, under the original equity and admiralty procedures all examination of witnesses was conducted in writing! (Wigmore on Evidence, § 799.) Our own discovery rules recognize two classes of depositions, those taken by oral examination, and those taken by written interrogatories. (Code Civ. Proc., § 2016.) Unlike Federal Rules of Civil Procedure, rule 47, and Federal Rules of Criminal Procedure, rule 24, both of which refer to the ‘conduct of the examination’ of prospective jurors, our rules are silent on the subject of the conduct of the examination and merely refer to ‘examination’ of prospective jurors without specifying any particular mode of examination.” (Rousseau v. West Coast House Movers (1967) 256 Cal.App.2d 878, 883 [64 Cal.Rptr. 655].)
Mrs. Klobucar was dismissed on peremptory challenge; Mrs. Rotman and Mrs. Hupp served as jurors.
See also People v. Hinshaw (1919) 40 Cal.App. 672, 674 [182 P. 59],
It is not a function of voir dire to educate the jurors as to the facts of the case, nor as to the principles of law which may be applicable. (See People v. Love (1960) 53 Cal.2d 843, 852 [3 Cal.Rptr. 665, 350 P.2d 705]; Rousseau v. West Coast House Movers (1967) 256 Cal.App.2d 878, 882-883 [64 Cal.Rptr. 655].)
Rousseau v. West Coast House Movers (1967) 256 Cal.App.2d 878, 883-884 [64 Cal.Rptr. 655], sets out five methods for jury voir dire.
“1. The court may turn all interrogation over to counsel and delegate to counsel the conduct of its examination of prospective jurors.
“2. The court may conduct an initial examination of prospective jurors and then permit counsel to conduct a general examination of prospective jurors.
“3. The court may conduct an initial examination of prospective jurors and then permit counsel to conduct an examination of prospective jurors on specific subjects only.
“4. The court may itself conduct the examination of prospective jurors and require the examination of prospective jurors by counsel to be conducted by interrogation through the court.
“5. The court may itself conduct the examination of prospective jurors and require examination by counsel to be conducted by interrogation through the court, but when positive answers on a particular subject develop, permit counsel to conduct an examination on that subject by direct oral interrogation.”
Language to the contrary in People v. Adams (1971) 21 Cal.App.3d 972 [99 Cal.Rptr. 122], is disapproved.
The dialogue between the judge and defense counsel is set out, supra, at pages 820-821.
Mrs. Meals served as foreperson of the jury.
Although each of the jurors asserted that he knew of no reason why he could not serve as an impartial juror, such assertions do not eliminate the necessity for additional reasonable inquiry to uncover concealed or subtle bias. Hafif, Adequate Voir Dire (1969) 44 State Bar. J. 858, 860; see Walker v. Greenberger (1944) 63 Cal.App.2d 457, 463-464 [147 P.2d 105]; Garry, Attacking Racism in Court Before Trial, in Minimizing Racism in Jury Trials (Ginger ed. 1969) page xxii, asserts that “The average judge’s idea of voir dire is just to ask ‘Can you be fair?’ Once the prospective juror has answered ‘yes,’ everything else is considered irrelevant and the judge passes on to the next juror, even though Adolph Hitler himself would have answered that question in the affirmative.”
We doubt that this is the average judge’s concept of voir dire, but the comment does illustrate the danger that a biased juror may be unwilling to confess that bias openly, and that questions to which there is a “right” and a “wrong” answer may be less likely to reveal such bias than more open-ended questions. See generally Blauner, Sociology in the Courtroom: The Search for White Racism in the Voir Dire in Minimizing Racism in Jury Trials (Ginger ed. 1969) pages 43-71; Broeder, Voir Dire Examinations: An Empirical Study (1965) 38 So.Cal.L.Rev. 503.
