OPINION

BIRD, C.J.

This court must decide the narrow issue as to whether the trial court was correct when it held that the pretrial release and detention system employed by the City and County of San Francisco violates the due process clauses of the state and federal Constitutions.

I

When an individual is arrested in San Francisco three methods of pretrial release are available: (1) citation (Pen. Code, §§ 853.5, 853.6); (2) bail (Pen. Code, § 1268 et seq.); or (3) own recognizance release (Pen. Code, § 1318 et seq.).

Release by citation is limited by police regulations to misdemeanor offenses where the arrestee has no outstanding warrants and resides in, or within 30 miles of, San Francisco. According to those regulations, a citation should not be issued, even to one charged with a misdemeanor, if (1) the identity of the arrestee is not ascertainable; (2) the arrestee requires medical examination or care that would not be provided if he were merely cited; (3) there is reasonable cause to believe the misdemeanor violation will continue; (4) there is a threat of danger or resistance to the public or law enforcement personnel; or (5) prosecution of the offense or of another offense would be jeopardized. Otherwise, release by citation is wholly within the discretion of the arresting officer.

Those arrested individuals, who are booked rather than cited (other than those detained for a parole or probation violation or those charged with a nonbailable offense), are allowed immediate release upon the posting of bail in the amount specified in the master bail schedule. (Pen. Code, § 1269b.) Release under the bail schedule does not entail inquiry into the detainee's family or community ties, employment history, financial condition, past record for appearance in court or any other evidence that the detainee will appear. The schedule sets forth the amount of bail in accordance with the seriousness of the offense charged. This sliding scale based on seriousness is used despite the fact that the evidence introduced below indicated that persons accused of misdemeanors are more likely to fail to appear at subsequent proceedings than are felony defendants.

Anyone who is not released on bail or citation must be arraigned without unnecessary delay and in any event within 48 hours of his arrest (not including Sundays and holidays). (Pen. Code, § 825.) Bail may be reset by the court at that time for those detainees still in custody. (See Pen. Code, §§ 815a, 823, 849.) When setting bail, the court considers the likelihood of the detainee appearing in court, the seriousness of the offense charged, and the detainee's previous criminal record. (Pen. Code, § 1275.) According to the evidence adduced below, San Francisco judges give little or no consideration to the financial resources of the detainee. The judge does not know whether the detainee will be able to meet the amount of bail that is set. As a result, the judge has no way of knowing how strong an incentive to appear is created by setting bail at a particular figure.

If an individual is not released on citation or does not post bail, he may seek release on his own recognizance. (Pen. Code, § 1318.) The great majority of detainees who follow this route simply do not have the funds to post bail. For this reason, own recognizance release is the poor person's alternative to bail.

In seeking release on their own recognizance, detainees may be assisted by the OR project. According to the record, the OR project in San Francisco processes OR release applications in the following manner. Project staff members conduct interviews with those detainees they are able to contact in city prison. The prior record of the detainee is summarized in the project's report, and relevant information regarding the detainee's community ties is verified by the project whenever possible. The police report on the incident leading to the arrest is obtained by the project from police files and is attached to the application. A point system, which gives positive points to such facts as residence, family or employment in the Bay Area, is used to evaluate the detainee's likelihood of appearing for future court proceedings. The highest possible score is 12 positive points. Prior convictions contribute negative points, and persons with less than five points are automatically excluded from further consideration by the OR project. If an applicant scores five or more points, his case is presented to the court by staff members of the project.

The trial court found that in San Francisco, when applications are presented to the court, the presumption is against OR release and the detainee bears the burden of showing that his application is meritorious. Further, such release is granted or denied as a matter of grace and is totally within the unfettered discretion of the trial judge. (Pen. Code, § 1318.2.) Evidence was introduced which indicated that judges apply widely different criteria in deciding whether to grant OR release, with the result that virtually identical applications are disposed of differently. Overall, only 17 percent of those individuals arrested and interviewed by the OR project were released on their own recognizance. It was found that the hearings with respect to OR release are brief and informal. Judges generally make their decision without providing written findings or even stating on the record their reasons for denying release.

Approximately one-half of all detainees in San Francisco are unable to post bail and are not released on their own recognizance. As a direct result, they remain in jail until their cases are resolved. There was unanimous agreement among the witnesses at the trial below that many of these persons could safely be released on OR or supervised OR. The defendants' own witness, professional bondsman Al Graf, testified that "the people who are being released are the affluent. The poor are staying in jail."

In a taxpayer action filed pursuant to Code of Civil Procedure section 526a, plaintiffs attacked the statutes providing for pretrial release and San Francisco's application of those statutes. The defendants, former San Francisco Chief of Police Donald M. Scott and former Sheriff Richard D. Hongisto, maintained custody of all detainees held by the City and County of San Francisco prior to trial. Defendant Hongisto admitted in his answer that the system was unconstitutional, but refused to alter the existing practices until the system was officially declared unconstitutional. Defendant Scott denied the allegations in the complaint and contended that the detention system was lawful.

Following a seven-day trial, the court held that plaintiffs had standing to sue under section 526a of the Code of Civil Procedure, that a true and genuine case or controversy existed, and that the court had jurisdiction to adjudicate the issues. Further, the court held that the challenged statutes providing for pretrial release, as employed in San Francisco, violated the due process clauses of the federal and state Constitutions in that: (1) the prosecution is not required to assume the burden of proving that bail is necessary to assure the presence of the detainee in court; and (2) the courts are not required to furnish a written statement of reasons for denial of own recognizance release. The trial court further held that the expenditure of revenues by San Francisco to implement its existing system of pretrial release and detention was illegal until and unless present practices and procedures are modified to provide the missing procedural safeguards. This appeal followed.

II

The testimony in the record, which is corroborated by numerous courts and commentators from this and other jurisdictions, indicates that the private interests affected by the decision as to whether an individual will be released prior to trial are great. That decision affects the detainee's liberty, a fundamental interest second only to life itself in terms of constitutional importance. ( People v. Saffell (1979) 25 Cal.3d 223, 228 [ 157 Cal.Rptr. 897, 599 P.2d 92]; People v. Olivas (1976) 17 Cal.3d 236, 251 [ 131 Cal.Rptr. 55, 551 P.2d 375].) A detainee who is denied pretrial release remains in jail, often for periods of several months, despite the fact that there has been no determination of his guilt or innocence. Confined in a 12-man "gang cell" measuring 23 feet, 7 inches by 8 feet, 4 inches, he is furnished jail food which consists of a sandwich or a soft substance that can be eaten with a spoon. He sleeps on a bunk without pillows or sheets. He is allowed no visitors or contact with the outside world except for court-related appearances and conversations by telephone through a glass partition. Exercise is limited to a one-hour period two or three times a week. In short, a denial of pretrial release inflicts a direct "grievous loss" upon the detainee. (Cf. Morrissey v. Brewer, supra, 408 U.S. at p. 481 [33 L.Ed.2d at p. 494].)

There are other important deprivations which follow pretrial incarceration. The detainee's ability to adequately prepare a defense is greatly curtailed and consultation with an attorney is severely impaired. The only place an attorney can speak with his client is in the jail itself, a place frequently located far from, and lacking the facilities at, the attorney's office. Moreover, the detainee's communications at the jail may be inhibited due to the lack of privacy and the common fear that the jail may be "bugged." (See Cohen, supra, at p. 1028; Hongisto, supra, at p. 578.)

Imprisonment severely hinders the detainee's ability to gather evidence and interview witnesses. Consequently, the effectiveness of counsel's assistance and the detainee's right to a fair trial are generally impaired. (See Trends, supra, at p. 689; Cohen, supra, at pp. 1028-1029; Beyond the Bail System, supra, at pp. 1123-1124; Hongisto, supra, at p. 578.) Further, since incarceration generally means loss of income and often employment, the detainee's ability to retain an attorney of his own choosing may be limited. (See Thaler, supra, at p. 452.) If the detainee is unable to hire a private attorney, he must rely on the services of often overworked court-appointed counsel.

Finally, the fact that the detainee is frequently brought to the courtroom in jail clothing, in handcuffs or otherwise in obvious custody — as opposed to entering freely with counsel and perhaps his family — often engenders subtle prejudices in the judge and jury that necessarily interfere with the detainee's right to a fair trial. (See Trends, supra, at p. 690; Cohen, supra, at p. 1029; Goldfarb, Ransom (1965) p. 42 [hereafter Goldfarb]; Wald, Pretrial Detention and Ultimate Freedom: A Statistical Study (1964) 39 N.Y.U.L.Rev. 631, 632.)

Pretrial detention also has important consequences for the detainee outside the courtroom. It may imperil his job, interrupt his source of income, and impair his family relationships. However, the burdens associated with pretrial detention are by no means limited to the detainee and his family. The total costs of pretrial confinement constitute a drain on public funds as well. (Cf. Morrissey v. Brewer, supra, 408 U.S. at p. 477 [33 L.Ed.2d at p. 492]; see also People v. Vickers (1972) 8 Cal.3d 451, 458 [ 105 Cal.Rptr. 305, 503 P.2d 1313]; Lasker, Presumption Against Incarceration, supra, 7 Hofstra L.Rev. at p. 413; Committee on Crime, supra, at pp. 23-25; Hongisto, supra, at pp. 578-579.) The most obvious costs are those of providing the detainee with food, shelter and clothing, as well as maintaining security in the jail. These expenditures are substantial. (Committee on Crime, supra, at pp. 23-24.) Moreover, when ancillary costs are considered, such as welfare payments to families of detainees who lose their income, the burden becomes even larger.

Beyond the monetary costs, pretrial detention spawns additional, more subtle social burdens. The testimony of Chief Deputy Sheriff Bangston, the person charged with the supervision of the San Francisco County jails, is instructive on this point: "The other reason, and I'm not referring to a prisoner that's in and out, or whatever, but to a person that has been in once or twice, has had very few arrests, that type is susceptible to the influence, if you keep him in jail, and his character and moral standards go by. Such as, if you take a person with one juvenile arrest and then he reaches maturity and takes a fall, is arrested and ends up in jail, quite often the influence that he suffers in jail will turn him to an extent anti-social, and anti-establishment, and anti-so-called accepted system, he will try to buck it. I can't think of anyone coming to jail for the first time, in spite of their moral strength, that will not be influenced." (Cf. Morrissey v. Brewer, supra, 408 U.S. at p. 484 [33 L.Ed.2d at p. 496]; see also, Thaler, supra, at p. 454; Lasker, Presumption Against Incarceration, supra, 7 Hofstra L.Rev. at p. 411; O'Rourke Carter, The Connecticut Bail Commission (1970) 79 Yale L.J. 513; Comment, Incarcerating the Innocent, Pretrial Detention in Our Nation's Jails, supra, 21 Buffalo L.Rev. at pp. 903-904.)

Balanced against these substantial interests favoring pretrial release are several competing interests. The government's interest in assuring the presence of the accused at all court proceedings is a compelling one. The government also has a substantial interest in seeing that it achieves its objective of assuring the accused's presence at future proceedings at a reasonable cost.

Plaintiffs urge that the procedures employed in San Francisco do not properly strike the balance between these governmental and nongovernmental interests. Plaintiffs contend, and the trial court held, that due process requires both the burden of producing evidence and the burden of proof to be borne by the prosecution at the OR hearing. These two rulings must be evaluated separately.

The burden of producing evidence is "the obligation of a party to introduce evidence sufficient to avoid a ruling against him on the issue." (Evid. Code, § 110.) The sole issue at the OR hearing is whether the detainee will appear for subsequent court proceedings if released OR. (See In re Underwood (1973) 9 Cal.3d 345, 348 [ 107 Cal.Rptr. 401, 508 P.2d 721].) (2) To answer this question the trial court must consider the following factors: (1) the detainee's ties to the community, including his employment or other sources of income (e.g., welfare payments), the duration and location of his residence, his family attachments, his property holdings, and any independent reasons for wanting to leave or remain in the community (e.g., parole or immigration status); (2) the detainee's record of appearance at past court hearings or of flight to avoid prosecution; (3) the severity of the sentence the detainee faces. (See In re Podesto (1976) 15 Cal.3d 921, 934-935 [ 127 Cal.Rptr. 97, 544 P.2d 1297].) (3) In the present case, the trial court found that the prosecution should bear the burden of producing evidence to establish the detainee's ties to the community. However, the detainee is clearly the best source for this information and for names of individuals who could verify such information. Moreover, the detainee has a substantial incentive to cooperate in providing this information. If the burden of producing this evidence were placed on the prosecution, that incentive would disappear. The government would then have to conduct its own independent investigation, a costly and time-consuming undertaking. Since the government would not be able to gather information concerning the detainee's community ties as expeditiously as could the detainee, a dilemma would result. Either the OR hearing would have to be delayed — causing the prolonged detention of individuals entitled to release — or the hearing would proceed with the prosecution unable to sustain its burden — forcing the court to rule in favor of the release of a greater number of individuals who might fail to appear. Such a situation would serve the interests of neither the detainee who merits pretrial release nor the government. Therefore, this court is persuaded that due process does not require the prosecution to bear the burden of producing evidence of the detainee's lack of community ties. The trial court erred when it held to the contrary.

(4) Different considerations govern the proper allocation of the burden of producing evidence on the detainee's record of appearance at prior court hearings and the severity of the sentence he faces. The severity of the potential sentence can be readily determined by the court from the complaint and the applicable provisions of the Penal Code or other codes cited. The detainee's record of appearance at past court hearings can sometimes be discerned from his "rap sheet." In other cases, this information should be relatively easy and inexpensive for the prosecution to secure. Accordingly, this court concludes that the prosecution should bear the burden of producing evidence on these issues.

A separate question is presented by the proper allocation of the burden of proof. The burden of proof is "the obligation of a party to establish by evidence a requisite degree of belief concerning a fact in the mind of the trier of fact or the court." (Evid. Code, § 115.) It is a rule that tells the factfinder how to decide close cases. (See Underwood, The Thumb on the Scales of Justice: Burdens of Persuasion in Criminal Cases (1977) 86 Yale L.J. 1299 [hereafter Underwood].) The court below found that this burden has in practice been borne entirely by the detainee at the OR hearing. The operational effect of this practice is to create among trial courts a ". . . Pavlovian response of money bail [and hence a denial of OR release] to every uncertainty concerning the defendant." (Younger, supra, at p. 266; see also, Thaler, supra, at p. 446, fn. 28.) As a result, many detainees who could safely be released OR are nevertheless deprived of their freedom.

An individual's interest in his freedom has always been held sacrosanct. For this reason, it has been a basic tenet of "our society that it is far worse to convict an innocent man than to let a guilty man go free." ( In re Winship (1970) 397 U.S. 358, 372 [25 L.Ed.2d 368, 380, 90 S.Ct. 1068] [conc.opn. of Harlan, J.]; Patterson v. New York (1977) 432 U.S. 197, 208 [53 L.Ed.2d 281, 291, 97 S.Ct. 2319].) Placing the burden of proof on the government is one means by which our system of justice gives voice to this precept. (See Underwood, supra, at p. 1307.) The United States Supreme Court has eloquently explained the reason for this allocation of the burden of proof: "In all kinds of litigation it is plain that where the burden of proof lies may be decisive of the outcome. [Citations.] There is always in litigation a margin of error, representing error in factfinding. . . . Where one party has at stake an interest of transcending value — as a criminal defendant his liberty — this margin of error is reduced as to him by the process of placing on the other party the burden of producing a sufficiency of proof in the first instance, and of persuading the factfinder at the conclusion of the trial of his guilt beyond a reasonable doubt. . . ." ( Speiser v. Randall (1958) 357 U.S. 513, 525-526 [2 L.Ed.2d 1460, 1472, 78 S.Ct. 1332]; accord Mullaney v. Wilbur (1975) 421 U.S. 684, 701 [44 L.Ed.2d 508, 520, 95 S.Ct. 1881].)

This court has expressed similar views. (5) Thus, the prosecution has been held to bear a heavy burden of proof "in any proceeding in which the state threatens to deprive an individual of his 'good name and freedom.'" ( People v. Burnick (1975) 14 Cal.3d 306, 324 [ 121 Cal.Rptr. 488, 535 P.2d 352] [mentally disordered sex offender hearing]; accord Conservatorship of Roulet (1979) 23 Cal.3d 219, 229-230 [ 152 Cal.Rptr. 425, 590 P.2d 1] [appointment of conservator]; People v. Thomas (1977) 19 Cal.3d 630, 641 [ 139 Cal.Rptr. 594, 566 P.2d 228] [narcotics addict commitment proceeding]; In re Arthur N. (1976) 16 Cal.3d 226, 240-241 [ 127 Cal.Rptr. 641, 545 P.2d 1345] [commitment of a ward to the Youth Authority].)

The logic of those cases is applicable here. If an adverse ruling is made at the OR hearing, the detainee's loss of liberty is total. He is incarcerated, frequently for a substantial period of time, in San Francisco's county jail, which has been characterized as "one of the worst detention facilities in the state." (Committee on Crime, supra, at p. 13.) Incarceration not only restricts the detainee's freedom but also impairs his ability to prepare a defense and disrupts his employment, family and social relationships. ( Ante, at pp. 434-437.) As a result of an adverse ruling at the OR hearing, the detainee also suffers the stigma of a "loss of good name." (See Thaler, supra, at pp. 452-454.) Pretrial imprisonment is likely to be mistaken for a finding of the detainee's guilt rather than being recognized as his inability to make bail or persuade the judge that he would appear at future proceedings. At the very least, the detainee's removal from his home, job and community broadcasts the fact of his arrest.

Moreover, the threat of an unwarranted restraint on an individual's liberty is at its greatest where the decision being made is predictive in nature. ( People v. Burnick, supra, 14 Cal. 3d at p. 328; see also Conservatorship of Roulet, supra, 23 Cal.3d at pp. 234-235.) To deprive an individual of his freedom on the basis of speculation about his future conduct is contrary to the presumption of innocence that "lies at the foundation" of our judicial system. (See Coffin v. United States (1895) 156 U.S. 432, 453 [39 L.Ed. 481, 491, 15 S.Ct. 394].) Such decision making is also peculiarly subject to abuse and threatens to undermine the respect and confidence of the community in the uniform application of the criminal law. (See In re Winship, supra, 397 U.S. at p. 364 [25 L.Ed.2d at p. 375].)

There is an additional consideration involved in the case before this court. (6) A major function of the allocation of the burden of proof is to offset the effect of distortions in the fact-finding process that operate against the detainee. ( Conservatorship of Roulet, supra, 23 Cal.3d at p. 233; see also Underwood, supra, at pp. 1306-1307.) There are several sources of such distortion at the OR hearing.

Distortion results from the fact that it is difficult for a detainee to marshal any tangible evidence of his community ties. His incarceration prevents him from effectively locating witnesses or gathering other evidence to establish his local contacts and personal reliability. Some courts may be reluctant to accept the detainee's oral representations if unverified by other sources. (Cf. Wolff v. McDonnell (1974) 418 U.S. 539, 583 [41 L.Ed.2d 935, at p. 966, 94 S.Ct. 2963] [conc. and dis. opn. of Marshall, J.]; Goldfarb, supra, at pp. 157-158.) Therefore, he may remain confined merely because he is unable to produce evidence, beyond his own word, of his community ties, rather than because such ties are lacking.

Distortion also results from deliberate "overcharging" by the district attorney, a not infrequent practice according to evidence presented at trial. Overcharging — the filing of more charges than are warranted by the facts — gives the court the false impression that the detainee will be eligible for a greater sentence than is likely to be the case. This gives an inaccurate picture to the trial court of the detainee's likelihood of fleeing the jurisdiction.

Thus, the value of placing the burden of proof upon the prosecution concerning the detainee's likelihood of appearing for future court proceedings is threefold. It helps to preserve the respect for the individual's liberty and for the presumption of innocence that lies at the foundation of our judicial system, to maintain the respect and confidence of the community in the uniform application of the law and to systematically correct certain biases inherent in the OR decision-making process.

Moreover, placing the burden of proof on the prosecution should achieve these goals without significantly harming the government's interests. These interests are compromised only if a higher percentage of arrestees fail to make their scheduled court appearances. However, the defendants in the present case were unable to present any evidence whatsoever to establish that an increase in the number of OR releases in San Francisco would result in a significantly higher failure-to-appear rate. Indeed, all witnesses agreed that many persons were detained in San Francisco jails who could safely be released OR. Several witnesses opined that even if nearly all detainees were so released, the failure-to-appear rate would not increase substantially.

The experiences in other jurisdictions, as reported by witnesses at the trial below and by commentators, substantiate these conclusions. (E.g., O'Rourke Carter, The Connecticut Bail Commission, supra, 79 Yale L.J. at p. 515; Hongisto, supra, at pp. 635-636; Comment, The Bail System and Equal Protection (1969) 2 Loyola L.A.L.Rev. 71, 80-81; Note, Pretrial Release in California: Proposed Reforms of an Unfair System (1977) 8 Pacific L.J. 841, 853.) The courts of Oregon and of the District of Columbia operate under systems that create a presumption in favor of OR release. (Ore. Rev. Stat., § 135.245(3); 18 U.S.C. § 3146; Wood v. United States (D.C. Cir. 1968) 391 F.2d 981, 983.) As a result, a significantly higher percentage of detainees is released OR in those jurisdictions than in San Francisco. The uncontradicted statistical evidence presented at trial indicates that despite the greater rate of OR release, the failure-to-appear rate for those released OR was no higher in those jurisdictions than in San Francisco and was no greater than the failure-to-appear rate for those released on money bail in those jurisdictions. (See also Note, Pretrial Release in California: Proposed Reforms of an Unfair System, supra, 8 Pacific L.J. at pp. 861-862; Younger, supra, at p. 275.)

The director of the San Mateo OR project testified that the administrators of that project were so pleased with its initial success, they lowered the number of points required for a release recommendation from five to four. As a result, more detainees were released OR, yet the gross failure-to-appear rate remained only approximately 2 percent. Similar testimony was received from the administrators of the New York and Philadelphia pretrial services agencies. Those cities achieved OR release rates significantly higher than San Francisco without any significant increase in the failure-to-appear rate. (See also Comment, The Bail System and Equal Protection, supra, 2 Loyola L.A.L.Rev. at p. 80.)

Several reasons exist to explain why an individual who is released without having posted bail returns faithfully to make his court appearances. First, failure to appear following OR release is a separate offense. (Pen. Code, §§ 1319.4 and 1319.6.) Second, if the individual is innocent, he has the incentive to appear in order to prove it. Even if he is not innocent, he has the incentive to appear in order to preserve his position in plea bargaining and to establish a record of reliability that may benefit him in the future (e.g., at the time of sentencing). Third, the individual realizes that if he fails to appear now and is subsequently arrested for a separate offense, he will not likely be granted OR release at that time. Finally, there are intangible factors such as the individual's sense of responsibility after having given his word.

The defendants were unable to affirmatively demonstrate in the trial court that the government's interests in seeing that arrestees make their required appearances in court would be jeopardized by placing the burden of proof on the prosecution. Further, the evidence presented at trial by the plaintiffs, including the experiences of other jurisdictions, indicates that the government's interests would not be compromised.

Finally, placing the burden of proof on the prosecution will not unduly increase the government's administrative costs. In contrast to the burden of producing evidence, the burden of proof imposes no additional costs or obligations at the OR hearing itself. The only added burden that might be associated with this additional procedural safeguard is the cost of locating and bringing to court any additional individuals who fail to appear for their scheduled appearances. However, since it does not appear that the failure-to-appear rate would significantly increase, the relative costs (i.e., the ratio of total costs to the number of detainees released) should remain approximately the same, if not decrease. Moreover, the increase in absolute costs that this would entail should not be great. (See Cohen, supra, at p. 1030.) Any additional costs created by placing the burden of proof on the prosecution should be more than offset by the savings resulting from having to maintain fewer persons in custody. (See Hongisto, supra, at pp. 578-579; Younger, supra, at pp. 264-265; Committee on Crime, supra, at pp. 23-25.)

(7) For the several reasons discussed above, this court has determined that the probable value of placing the burden of proof on the prosecution would be great and that the potential harm to the government's interests, including any administrative costs that the procedural requirement might entail, would be minimal. Accordingly, it is concluded that due process requires the burden of proof concerning the detainee's likelihood of appearing for future court proceedings to be borne by the prosecution at the OR hearing.

Finally, this court must consider whether due process requires a court to issue a written statement of reasons whenever OR release is denied. In recent years, this court as well as the United States Supreme Court has had occasion to emphasize in a wide variety of contexts that due process requires government decisions, which affect important individual interests, to be accompanied by a statement of reasons explaining the basis for such decisions. (E.g., In re Sturm (1974) 11 Cal.3d 258, 269-270 [ 113 Cal.Rptr. 361, 521 P.2d 97] [denial of parole]; People v. Ramirez, supra, 25 Cal.3d at p. 276 [exclusion from rehabilitation center]; Morrissey v. Brewer, supra, 408 U.S. at pp. 487, 489 [33 L.Ed.2d at pp. 497-499] [revocation of parole]; Wolff v. McDonnell, supra, 418 U.S. at p. 564 [41 L.Ed.2d at p. 955] [revocation of good-time credits]; Kent v. United States (1966) 383 U.S. 541, 561 [16 L.Ed.2d 84, 97, 86 S.Ct. 1045] [juvenile court's waiver of jurisdiction].)

(8) This court recently explained the worthy purposes such procedures serve. "They help to assure a realistic review by providing a method of evaluating a judge's decision or order; they guard against careless decision making by encouraging the trial judge to express the grounds for his decision; and they preserve public confidence in the fairness of the judicial process." ( In re John H. (1978) 21 Cal.3d 18, 23 [ 145 Cal.Rptr. 357, 577 P.2d 177]; accord In re Podesto, supra, 15 Cal.3d at p. 937.)

These purposes are particularly pertinent in the setting of this case because it is not unusual for judges to keep a detainee in custody for punitive purposes or as a means of preventive detention. (See also Mosk, The Purpose of Bail in the Administration of Justice, supra, 54 Chi. Bar Record at p. 186; Goldfarb, supra, at pp. 46-49; Thaler, supra, at p. 447.) Whatever may be said as to the propriety of these considerations where a defendant seeks bail on appeal ( In re Podesto, supra, 15 Cal.3d at p. 935), they are not proper considerations where, as at the pretrial OR hearing, the detainee has not been convicted of any crime. ( In re Underwood, supra, 9 Cal.3d at pp. 348, 350.) Plaintiffs urge that the requirement of a written statement of reasons for a denial of OR release would reduce the incidence of these improper uses of pretrial detention.

Moreover, it is argued that requiring a written statement of reasons for the denial of OR release would ensure that a detainee's dignitary interest is recognized. Plaintiffs note that in Ramirez, supra, 25 Cal.3d at page 276, this court said, "'[t]he respect for individual autonomy that is at the foundation of procedural due process imposes a distinct obligation upon the government to explain fully its adverse status decision.'" Preserving the appearance of fairness is particularly important in the pretrial detention setting. As Justice Marshall said in Wolff v. McDonnell, supra, 418 U.S. at page 589 [41 L.Ed.2d at p. 970] (conc. and dis. opn.), quoting Palmigiano v. Baxter (1st Cir. 1973) 487 F.2d 1280, 1283: "'There is nothing more corrosive to the fabric of a public institution such as a prison than a feeling among those whom it contains that they are being treated unfairly.'" (Accord Wright v. Enomoto (N.D. Cal. 1976) 462 F. Supp. 397, 403, affd. (1978) 434 U.S. 1052 [55 L.Ed.2d 756, 98 S.Ct. 1223]; Payne v. Superior Court (1976) 17 Cal.3d 908, 922 [ 132 Cal.Rptr. 405, 553 P.2d 565].)

However, this court has not required written findings in every type of proceeding. (E.g., In re John H., supra, 21 Cal.3d 18 [decision to commit a juvenile to the Youth Authority]; People v. Edwards (1976) 18 Cal.3d 796 [denial of probation [ 135 Cal.Rptr. 411, 557 P.2d 995]].) The administrative burden created by requiring a written statement of reasons must be weighed against the nongovernmental interests. In the present case, that burden would be particularly acute.

The volume of cases affected would be far greater in the present context than in any setting where this court has previously granted the requested relief. The right to a written statement of reasons for denial of pretrial release would apply to virtually every arrestee, not just to a fraction of those found guilty. (Compare In re Podesto, supra, 15 Cal.3d 921; In re Sturm, supra, 11 Cal.3d 258.)

The increase in amount of judge time per OR hearing also militates against imposing a requirement of a written statement of reasons. A finding by the court that one specific factor is lacking is not usually sufficient to deny an application for OR release. Thus, the court would be duty bound to make written findings on a multitude of factors on each occasion where OR release is denied.

It is also significant that there are less burdensome procedures available that would at least partially safeguard the interests sought to be protected by a requirement of a written statement of reasons. Although not compulsory, an oral statement of reasons for denial of pretrial release would be beneficial. (Cf., People v. Edwards, supra, 18 Cal.3d at p. 805, fn. 12.) Moreover, an arrestee is entitled to "an automatic review of the order fixing the amount of his bail" within "five days from the time of the original order fixing the amount of his bail on the original accusatory pleading." (Pen. Code, § 1320.) (9) Since the Constitution does not compel a trial judge to issue a written statement of reasons whenever OR release is denied, the trial court erred when it found to the contrary.

(10) In summary, this court holds that: (1) the prosecution must bear the burden of producing evidence of the detainee's record of nonappearance at prior court hearings and of the severity of sentence the detainee faces; (2) the detainee should bear the burden of producing evidence of community ties; (3) the prosecution must bear the burden of proof concerning the detainee's likelihood of appearing at future court proceedings; and (4) the court is not constitutionally required to issue a statement of reasons when OR release is denied.

(11) Section 526a authorizes a taxpayer to file "[a]n action to . . . prevent[ ] any illegal expenditure of . . . funds . . . of a . . . city and county of the state. . . ." "The primary purpose of this statute, originally enacted in 1909, is to 'enable a large body of the citizenry to challenge governmental action which would otherwise go unchallenged in the courts because of the standing requirement.'" ( Blair v. Pitchess (1971) 5 Cal.3d 258, 267-268 [ 96 Cal.Rptr. 42, 486 P.2d 1242, 45 A.L.R.3d 1206].) That section provides "a general citizen remedy for controlling illegal governmental activity." ( White v. Davis (1975) 13 Cal.3d 757, 763 [ 120 Cal.Rptr. 94, 533 P.2d 222]; Wirin v. Parker (1957) 48 Cal.2d 890, 894 [ 313 P.2d 844], citation omitted.)

(12) California courts have consistently construed section 526a liberally to achieve its remedial purpose. Accordingly, the existence of individuals directly affected by the challenged governmental action — here pretrial detainees — has not been held to preclude a taxpayers' suit. Numerous decisions have affirmed a taxpayer's standing to sue despite the existence of potential plaintiffs who might also have had standing to challenge the subject actions or statutes. For example, in Blair, supra, 5 Cal.3d 258, this court permitted taxpayers to maintain an action challenging the claim and delivery statute even though aggrieved persons directly affected by its operation also had standing to sue.

Nevertheless, relying on Gould v. People (1976) 56 Cal.App.3d 909 [ 128 Cal.Rptr. 743] and Di Suvero v. County of Los Angeles (1977) 73 Cal.App.3d 718 [ 140 Cal.Rptr. 895] , defendants argue that plaintiffs cannot maintain this suit because aggrieved pretrial detainees already have standing. Such reliance is misplaced. Gould sought to avoid the misuse of taxpayer suits as vehicles for mounting collateral attacks on the correctness of judicial rulings in particular cases. That threat is posed by a taxpayer suit only when a person "file[s] a collateral action against a judge under the guise of a taxpayer's suit contesting the outcome of any civil or criminal action in which he believe[s] the trial court ruled erroneously." ( Gould v. People, supra, 56 Cal.App.3d at p. 922.) Unlike the plaintiffs in Gould, the plaintiffs in the present case have neither joined judicial officers as party defendants nor sought to upset any particular judge's decision denying bail or OR release. Moreover, the plaintiffs in the present case do not have another existing forum in which to challenge the pretrial detention system. Di Suvero represents an unwarranted extension of Gould. Unlike the plaintiffs in Gould, the Di Suvero taxpayer was not a defendant in any criminal action and, therefore, had no other forum in which to press his claim. More importantly, the threat of a collateral attack upon a pending action was not present in Di Suvero, since that taxpayer's suit did not contest the outcome of a particular case.

The holding in Di Suvero is contrary to the many cases in which this court has upheld a taxpayer's right to bring a suit despite the existence of directly affected potential litigants. (Cf., ante, fn. 24.) These decisions are not discussed in Di Suvero or in Gould, upon which Di Suvero relied. This court reaffirms that taxpayers may maintain an action under section 526a to challenge an illegal expenditure of funds even though persons directly affected by the expenditure also have standing to sue. To the extent that Di Suvero and Gould are inconsistent with this rule, they are hereby disapproved.

(13) Next, it is contended that section 526a does not authorize this action for declaratory relief. Section 526a permits a taxpayer action "to obtain a judgment . . . restraining and preventing any illegal expenditure" of public funds. (Italics added.) While such language clearly encompasses a suit for injunctive relief, taxpayer suits have not been limited to actions for injunctions. Rather, in furtherance of the policy of liberally construing section 526a to foster its remedial purpose, our courts have permitted taxpayer suits for declaratory relief, damages and mandamus. To achieve the "socially therapeutic purpose" of section 526a, "provision must be made for a broad basis of relief. Otherwise, the perpetration of public wrongs would continue almost unhampered." ( The Public Interest Litigant, supra, 10 Loyola L.A.L.Rev. at p. 340.) Accordingly, section 526a authorizes this suit for declaratory relief. (14) It is further argued that the requisite adverse interests are lacking in this case. This contention is based on the assertions that (1) after the trial of this action was concluded, the chief of police was relieved of all his prior responsibility for pretrial detainees; and (2) the only defendant presently responsible for pretrial detainees in San Francisco, the sheriff, conceded prior to trial that the challenged system was unconstitutional.

The trial record and briefs filed before this court belie the alleged lack of interest. The chief of police has vigorously opposed plaintiffs' contentions. As in Blair, "the extensive briefs in this case demonstrate . . . [that] [t]here is no danger . . . the court will be misled by the failure of the parties adequately to explore and argue the issues." ( Blair v. Pitchess, supra, 5 Cal.3d at p. 270.) (15) Defendants next contend that the San Francisco Superior Court bench is an indispensable party to this action and that the failure to join it deprives this court of jurisdiction. Code of Civil Procedure section 389, revised in 1971 to bring it into conformity with rule 19, Federal Rules of Civil Procedure, provides in relevant part that "a person . . . shall be joined as a party in the action if . . . (2) he claims an interest relating to the subject of the action and is so situated that the disposition of the action in his absence may (i) as a practical matter impair or impede his ability to protect that interest. . . ."

The only interests protected by section 389 are personal ones which may be prejudiced in a concrete way by a judgment rendered in the absence of joinder. (See Bank of California v. Superior Court (1940) 16 Cal.2d 516 [ 106 P.2d 879].) For example, in Serrano v. Priest, supra, 18 Cal.3d 728, this court considered whether the interests of the Governor and the Legislature in the constitutionality of the state's school financing scheme were such as to render them indispensable parties. The court held that the interests of the Governor and the Legislature as "lawmakers concerned with the validity of statutes enacted by them . . . [are] not of the immediacy and directness requisite to party status. . . ." ( Id., at p. 752.)

The interests of the judges charged with setting bail and deciding motions for own recognizance release are similarly remote. Judges are undoubtedly interested in any case which may affect the exercise of their discretion or the administration of justice. However, judicial interest is no greater here than in any other case which challenges the constitutionality of statutes or their practices. It does not rise to a personal stake in the outcome of the case. (Cf. Pettit v. Gingerich (D.Md. 1977) 427 F. Supp. 282, affd. 582 F.2d 869.) Here, as in Serrano, invocation of the doctrine of indispensability would "thwart rather than accomplish justice." ( Bank of California v. Superior Court, supra, 16 Cal.2d at p. 521.)

IV

The effect of today's decision is neither to undercut the constitutional right to bail guaranteed by the first clause of article I, section 12 of the California Constitution, nor to create a right to OR release in contravention of the second clause of that section. Nevertheless, the dissent seems to argue that today's decision modifies the absolute right to bail and discretionary right to OR release mandated by article I, section 12. Nothing could be further from the truth.

This court's decision in no way alters the detainee's right to bail. Release on own recognizance and release on bail are alternative and complementary systems. If the detainee is able and chooses to post the amount of bail established by the master bail schedule (Pen. Code, § 1269b) or set by the court (Pen. Code, §§ 815a, 1320), he will be released. The additional procedures required at an OR hearing by today's decision could not possibly interfere or conflict with the detainee's right to bail.

Placing the burden of proof on the prosecution concerning the likelihood that the detainee will appear at future court proceedings is not tantamount to creating a right to OR release and is not inconsistent with retention of discretion by the trial judge. If, after weighing the facts presented at the OR hearing in accordance with the requirements of procedural due process as set forth herein, the court believes the detainee is likely not to appear for subsequent court proceedings, OR release may be denied. Today's decision merely requires, in keeping with well established precedent, that the trial court not exercise its discretion arbitrarily. (See Ex Parte Hoge (1874) 48 Cal. 3, 5; In re Podesto, supra, 15 Cal.3d at p. 933.)

This is not the first time this court has been required to address purported conflicts between specific constitutional provisions and more general guarantees such as the equal protection or due process clauses of the state Constitution. In Hawkins v. Superior Court (1978) 22 Cal.3d 584 [ 150 Cal.Rptr. 435, 586 P.2d 916], it was argued that a finding that denial of a post-indictment preliminary hearing deprived the accused of the equal protection of the law was barred by article I, sections 14 and 23 of the California Constitution, which explicitly sanctioned the grand jury indicting process. In rejecting this construction, this court stated: "The state constitutional provision recognizing the grand jury's indicting function — article I, section 14 — is no bar to our holding herein. . . . [W]hile the Constitution authorizes the use of grand juries to indict criminal defendants, it leaves to the Legislature and the courts the task of developing procedures, consistent with other state constitutional provisions, for implementing that mode of initiating prosecutions." ( Id., at p. 594, fn. omitted; see also Serrano v. Priest, supra, 18 Cal. 3d at p. 773.) Similarly, in the present case, the courts have the task of developing procedures to ensure that release by bail and release on one's own recognizance are implemented in a constitutionally proper manner.

Article I, section 12 of the state Constitution was amended in 1974 by ballot Proposition 7, following a recommendation by the California Constitution Revision Commission. The commission's comment in support of its recommendation stated, "[t]he 'Own Recognizance' system presents a desired alternative to the bail system, which frequently works an injustice on those who cannot afford to post a bail bond." (Proposed Rev. of Cal. Const., pt. 5, Cal. Const. Rev. Com. (1971) p. 19; see also, Ballot Pamp., Proposed Amends. to Cal. Const. with arguments to voters, Gen. Elec. (Nov. 5, 1974), argument in favor of Prop. 7, p. 28.) This court is merely implementing the spirit of the 1974 amendment in holding that due process requires the prosecution to bear the burden of proof as to why a detainee would not be released on his own recognizance.

V

The judgment of the trial court is modified in two respects. The burden of producing evidence as to community ties is to be with the detainee and the requirement of a written statement by the court of the reasons for the denial of OR release is disapproved. As so modified, the judgment is affirmed. Plaintiffs are to recover their costs on appeal.
