Defendant appeals from an order finding him to be a person “in imminent danger of becoming addicted to narcotics ’ ’ and committing him to the custody of the Director of Corrections for placement in the narcotics addict rehabilitation program. (Welf. & Inst. Code, § 3051.)
We are once again called upon to resolve difficult questions concerning the manner and scope of review of narcotics addiction commitment proceedings. The statutory scheme (Welf. & Inst. Code, §§ 3000-3305) provides little guidance in this respect, and in a series of decisions we have therefore undertaken to delineate the appropriate remedies. (See, e.g.,
In re De La O
(1963)
On November 30, 1966, defendant pleaded guilty to one count of possession of marijuana, a felony. (Health & Saf. Code, § 11530.) His then counsel, Mr. Friedman, advised the court that he had reason to believe defendant was eligible for the narcotics addict rehabilitation program, and requested that the criminal proceedings be adjourned and proceedings for civil commitment be initiated under Welfare and Institutions Code section 3051. The court acceded to the request, and the following day the district attorney filed a petition for commitment. 1
After several continuances, the petition came on for hearing on January 3, 1967. Defendant’s new counsel, Mr. Berg, was apparently determined to resist his client’s commitment. He moved to withdraw the plea of guilty to the criminal charge, for an immediate jury trial on the issue of addiction, and to *114 disqualify the judge by peremptory challenge. The motions were denied. After hearing expert and lay witnesses presented by the district attorney and cross-examined by defense counsel, the court on January 13, 1967, found defendant to be in imminent danger of addiction and ordered him committed to the rehabilitation program.
On the same day, January 13, defendant through his counsel filed a notice of appeal from the order of commitment. On January 20, however, defendant through his counsel also filed a demand for a trial de novo on the issue of addiction. 2
I
At the outset, we put aside two contentions of defendant which challenge his conviction of possession of marijuana and hence may not be litigated on this appeal.
Under the law as it stood when this case was tried, a person who had been convicted of a crime in a municipal or superior court and was then committed to the narcotics addict rehabilitation program (Welf. & Inst. Code, §§ 3050, 3051) had two alternative routes open to him for raising claims of error occurring in the
criminal
trial. First, he could move for a new trial and, by special statutory provision, appeal directly from a denial of that motion. (Former Pen. Code, § 1237, subd. 2; see, e.g.,
People
v.
Meison
(1968)
But what he could not do—as defendant has here attempted —was to use liis right to appeal from the order of
civil
commitment as yet another vehicle to attack his criminal conviction.
(People
v.
Cordova
(1967)
At the time here relevant, moreover, such an attempted review of the judgment of conviction would necessarily have been premature: until the defendant was returned to court and sentenced after his rejection or release from the rehabilitation program (Welf. & Inst. Code, §§3053, 3200), the criminal charge had not been prosecuted to a “final judgment of conviction” within the meaning of the basic criminal appeal statute (former Pen. Code, § 1237, subd. I). 4
Before leaving this point, however, we pause to explain the relevance of our recent decision in
People
v.
Moore
(1968)
II
The trial court correctly took no action on defendant’s demand, made on January 20, 1967, for a jury trial de novo on the issue of addiction. One week earlier, on Janaury 13, defendant had filed his notice of appeal from the order of commitment; the “subject matter” of that appeal, on its face, was the entire order of the court.
6
It is code law that the taking of an appeal “stays all further proceedings in the court below upon the judgment or order appealed from, or upon the matters embraced therein” (Code Civ. Proc., §946). This rule governs in both civil
(Sacks
v.
Superior Court
(1948)
' It is true that the right to demand a trial de novo on the issue of addiction is specifically declared by statute (see fn. 2, ante); but we do not believe the Legislature intended thereby to require or even permit a defendant to attack the sufficiency of the evidence in a retrial and simultaneously to prosecute an appeal from the order of commitment. Among the practical difficulties of such a bifurcated remedy, at least one is immediately apparent: if the “subject matter” of the defendant’s appeal were limited by the issues he chose to present, the trial court would be compelled to wait for the several months ordi *117 narily consumed in the preparation of appellate briefs before it could learn whether or not it had jurisdiction to proceed with the trial de novo. A delay of those proportions, however, is impermissible. (See fn. 7, post.)
Nor is there any need for such a radical departure from the normal sequence of judicial review. A person who has been committed may deem himself aggrieved, for example, in two respects: i.e., that there has not been “strict compliance with each of the statutory prerequisites for maintenance of the proceeding”
(In re Raner
(1963)
The distinction is well illustrated by
People
v.
Whelchel
(1967)
We recognize that if the person committed thus awaits the outcome of the trial de novo before appealing on the ground of noncompliance with the procedural prerequisites of the commitment hearing, there will be some delay in presenting that issue for adjudication. But when measured against the average time required to process and decide an appeal on the merits, the delay will be negligible. 7 Here, too, practical considerations play their role: for example, if in the trial de novo the defendant should be found not to be addicted or in imminent danger thereof, an unnecessary appeal will have been avoided with a concomitant saving of the time and effort of the parties and the courts.
We conclude that there is no impediment to invoking, in these proceedings, the general rule that the taking of an appeal removes the challenged judgment or order from the jurisdiction of the trial court. For this reason, defendant’s belated demand for a trial de novo was properly deemed a nullity. 8
Ill
The next question relating to scope of review is the converse of that just discussed: if, as here, the defendant fails for any reason to relitigate the sufficiency of the evidence of addiction by means of a trial de novo, will a waiver of that *119 issue be inferred so as to bar him from raising it on a direct appeal from the order of commitment ?
To begin with, the statute expressly provides that if a person committed is dissatisfied with the order of the court he “may”—not “shall”—demand a trial de novo. (Welf. & Inst. Code, §§3050, 3051, 3108.) Elsewhere throughout the narcotics addict commitment law the Legislature has carefully distinguished between such terms,
9
and we cannot assume that its use of the permissive form in this context was a mistake. As we said in
In re Trummer
(1964)
supra,
The statute admittedly does not specify what the defendant “may” do in the alternative if he chooses not to demand a trial de novo, yet remains “dissatisfied.” It was to fill this gap that in
In re De La O
(1963)
supra,
We recognize that in
People
v.
Bruce (1966) supra,
On the other hand, “the burden of establishing addiction is on the .state rather than the individual, and the state should be encouraged to discharge that burden fully at the basic proceeding envisaged by the statute, which is the commitment hearing. The rule implied in Bruce will give the state an incentive to make only a minimum showing at that hearing, knowing that it cannot be challenged on appeal without a second opportunity to introduce evidence at a trial de novo. And as such trials are not often demanded in practice, the risk, of substantial numbers of persons being found addicted on inadequate evidence will increase accordingly.” (Belton, Civil Commitment of Narcotics Addicts in California (1968) 19 Hast.L.J. 602, 665.)
We need not resolve these conflicting considerations. The language in question has been criticized (Belton, op.cit. supra, at pp. 662-664), and was not essential to the decision in Bruce. 10 We adhere, however, to the teaching of Bruce (at p. 62 of 64 Cal.2d) that “Normally . . . a defendant who feels that he has been improperly committed for lack of evidence of his addiction should seek the remedy provided for in the statute, namely, to demand a trial de novo by jury or by court. ’ ’ (Italics added.) In so doing, the factual issue of addiction will be litigated at the trial level, which is the most appropriate forum; and should further review be called for, the appellate court will have the benefit of a more complete record than ordinarily is made at a summary commitment hearing. In short, a defendant need not be foreclosed from raising this issue on a direct appeal from the commitment order, but a trial de novo remains his “normal” and, for the reasons stated, his preferable remedy.
*121 IV
We turn, finally, to the merits of the issues that are properly before us.
On the first day of the commitment hearing, January 3, 1967, both court-appointed doctors gave their testimony, and defendant’s father testified on direct examination and began to testify on cross. He concluded that testimony on January 5, and on January 10 and 12 additional testimony was taken from an attorney acting as a friend of the court. It appears that the doctors were not present in the courtroom on the latter three hearing days. Defendant contends that their absence was in violation of Welfare and Institutions Code section 5564, which declares in part that “The judge shall compel the attendance of at least two medical examiners, who shall hear the testimony of all witnesses, ’ ’ and hence in violation of the Raner requirement of strict compliance with each of the statutory prerequisites of the commitment hearing.
The point is not well taken. At the time here relevant, section 3051 commanded only that the commitment proceedings shall be conducted “in substantial compliance” with, inter alia, section 5564.
11
We observed in
Bruce
(
In attacking the sufficiency of the evidence to support the finding of imminent danger of addiction, defendant
*122
complains that the doctors’ examinations of his condition were brief and that they observed no needle scars, withdrawal symptoms, or other physical evidence of addiction. The extent of such an examination, however, is relevant only to the weight to be given the doctor’s testimony. Nor is physical evidence of addiction essential to the determination here made, “if other evidence is sufficient to show repeated use of heroin [or other addictive drug] to the extent that the person has failed to solve his problems by socially accepted methods and that he is emotionally or physically dependent upon narcotics and is, therefore, in the opinion of qualified examiners either addicted thereto or in imminent danger of becoming so addicted.”
(People
v.
Bruce
(1966)
supra,
The record contains such evidence. Each doctor testified that in the course of his interview with defendant he admitted having used various dangerous drugs and such “hard” narcotics as cocaine, heroin, and opium. On the basis of these admissions and their appraisal of defendant’s lack of insight into his problems, the doctors testified that he had a compulsive need to úse such drugs and an increased tolerance of their effects, that he would revert to narcotic consumption if “turned loose on the streets,” and that he would benefit by commitment to the rehabilitation program. No objection was effectively voiced to the introduction of defendant’s admissions.
The foregoing testimony, although not overwhelming, is sufficient on appeal to support the finding that “by reason of repeated use of narcotics [defendant] is in imminent danger of becoming addicted to narcotics” (Welf. & Inst. Code, § 3051), as that phrase is defined in
People
v.
Victor
(1965)
supra,
The order is affirmed.
Traynor, C. J., McComb, J.. Peters, J., Tobriner, J., Burke, J., and Sullivan, J., concurred.
Notes
A copy of the petition was served on defendant and he was arraigned thereon. The clerk’s transcript recites that he “was asked if it was his desire that he be committed in accordance with the petition and he personally answered yes.’’ Drs. Hagan and Wark were appointed to examine defendant, and a copy of the order fixing the time and place of hearing was also served on him.
At the relevant time, Welfare and Institutions Code section 3051 provided in part that “If a person committed pursuant to this section, after conviction of a felony, is dissatisfied with the order of the court, he may demand a' hearing by a judge or jury in substantial compliance with the provisions of Section 5125 \sic-, the correct reference should have been to § 5572] of this code. ’ ’ All the statutes involved in this case have since been amended (see fn. 12, post), but a jury trial de novo on the issue of addiction may still be demanded by the person committed.
3 As will appear (Part III, post), that invalidity may be predicated either on errors of law or on insufficiency of the evidence.
In
People
v.
Gonzales
(1968)
Although the 1968 revision comes too late to apply to the case at bar, the result would in any event have been the same under its terms. Prom the phrase, “within the meaning of this section,” we infer that the amendment was meant to cure only the evil to which it was directed, i.e., the delayed appealability of the criminal judgment in this type of ease: under the new statute, such an appeal may now be noticed as soon as 90 days after the making of the order of commitment. But the statute was not intended to affect existing case law on the manner and scope of appeal from the commitment order itself. That appeal remains governed by Code of Civil Procedure section 963; it must therefore be noticed within the time provided for ordinary appeals in civil matters (Cal. Pules of Court, rule 2(a)), regardless of whether the defendant also intends to appeal from his criminal judgment at the proper time. Just as under the prior law, the manifest distinctions between the two proceedings may not be evaded by the device of grafting conviction-related issues onto an appeal from the order of commitment.
The evidence that defendant now seeks to challenge is a quantity of marijuana found on his premises; it was not introduced at the commitment hearing, and the order appealed from was predicated exclusively on the testimony of the court-appointed doctors as to the results of their independent examinations of defendant conducted after the filing of the petition for' commitment. This sequence is by far the most common in commitment proceedings arising after a criminal prosecution.
The notice simply recited in general terms that defendant appealed "from the commitment” entered on January 13, 1967.
The demand for a trial de novo must be made within 10 days after the order of commitment (Welf. & Inst. Code, §§ 3050, 3051); the trial must be held within 30 days from the date of the demand (Welf. & Inst. Code, § 3108) ; and any unreasonable tardiness in bringing the matter to trial may be remedied by writ of mandate (see
People
v.
Donel
(1967)
There is no merit in defendant’s contention that his trial counsel’s decision to appeal directly from the commitment order could not operate to “deprive” him of his right to a jury trial de novo because he did not “personally waive” such a trial. “The commitment procedures set up by the subject statute are in the nature of special civil proceedings unknown to the common law, and hence there is no right to jury trial unless it is given by the statute.” (In re De La O (1963) supra, 59 *119 Cal.2d 128, 150.) In contrast to the constitutional guarantee of a jury trial to all defendants charged with crime, the present statutory scheme places on the person committed the responsibility of malting a timely demand for a jury trial de novo if he desires one. Such a demand was not effectively made in this case.
Indeed, section 15 of the Welfare and Institutions Code declares that as used therein, “ ‘Shall’ is mandatory and ‘may’ is permissive.”
A1though Bruce did not demand a trial de novo, and we therefore deemed it waived, we nevertheless proceeded to review the evidence of addiction' and held it insufficient as a matter of law.
The actual cross-reference was to former section 5053; but as we noted in
