Opinion GEORGE, C. J. Proposition 21, titled the Gang Violence and Juvenile Crime Prevention Act of 1998 and approved by the voters at the March 7, 2000, Primary Election (Proposition 21), made a number of changes to laws applicable to minors accused of committing criminal offenses. As relevant here, the initiative measure broadened the circumstances in which prosecutors are authorized to file charges against minors 14 years of age and older in the criminal division of the superior court, rather than in the juvenile division of that court. Welfare and Institutions Code section 707, subdivision (d) (section 707(d)), confers upon prosecutors the discretion to bring specified charges against certain minors directly in criminal court, without a prior adjudication by the juvenile court that the minor is unfit for a disposition under the juvenile court law. Petitioners are eight minors accused of committing various felony offenses. As authorized by section 707(d), the People filed charges against petitioners directly in criminal court. Petitioners demurred to the complaint, contending that section 707(d) is unconstitutional on several grounds. The superior court overruled the demurrers, but the Court of Appeal, Fourth Appellate District, issued a writ of mandate directing the superior court to vacate its ruling and to sustain the demurrers. The Court of Appeal (by a two-to-one vote) held that section 707(d) violates the separation of powers doctrine (Cal. Const., art. Ill, § 3) by allowing the prosecutor to interfere with the court’s authority to choose a juvenile court disposition for minors found to have committed criminal offenses. In considering the validity of the Court of Appeal’s decision, we emphasize that this court is not confronted with any question regarding the wisdom of authorizing the prosecutor, rather than the court, to decide whether a minor accused of committing a crime should be treated as an adult and subjected to the criminal court system. In the present case, rather, we must decide whether section 707(d) satisfies minimum constitutional requirements; we are not called upon to resolve the competing public policies implicated by the measure, considered by the electorate when it voted upon Proposition 21, and discussed at length by numerous amici curiae who have filed briefs in support of petitioners or the People. As we shall explain, we conclude that a prosecutor’s decision to file charges against a minor in criminal court pursuant to section 707(d) is well within the established charging authority of the executive branch. Our prior decisions instruct that the prosecutor’s exercise of such charging discretion, before any judicial proceeding is commenced, does not usurp an exclusively judicial power, even though the prosecutor’s decision effectively can preclude the court from selecting a particular sentencing alternative. Accordingly, we disagree with the Court of Appeal’s conclusion that section 707(d) is unconstitutional under the separation of powers doctrine. Because the Court of Appeal held that the statute violates the separation of powers doctrine, the appellate court did not resolve the other constitutional challenges to section 707(d) raised by petitioners in that court. In order to prevent continued uncertainty regarding the status of numerous proceedings involving accusations of criminal conduct committed by minors, we shall resolve those remaining issues in the present case. As discussed below, we have reached the following conclusions with regard to these questions: (1) the absence of a provision requiring that a judicial fitness hearing take place before a minor can be charged in criminal court pursuant to section 707(d) does not deprive petitioners of due process of law; (2) prosecutorial discretion to file charges against some minors in criminal court does not violate the equal protection clause; and (3) Proposition 21 does not violate the single-subject rule, set forth in article II, section 8, subdivision (d), of the California Constitution, applicable to initiative measures. I By a single felony complaint filed in the superior court, the People charged petitioners with eight felonies: four counts of assault with a deadly weapon by means of force likely to produce great bodily injury against four victims (Pen. Code, § 245, subd. (a)(1)), two counts of willful infliction of injury upon an elder under circumstances likely to result in great bodily harm or death (id., § 368, subd. (b)(1)), and two counts of robbery (id., §211). The complaint alleged that these crimes were committed because of the victims’ race, color, religion, nationality, country of origin, ancestry, gender, disability, or sexual orientation, and while petitioners acted in concert (id., § 422.75, subd. (c)), and that some of the petitioners personally inflicted great bodily injury upon the victims (id., § 12022.7, subd. (a)). Finally, the complaint alleged that four petitioners were 16 years of age or older at the time they committed the offenses, and that the remaining four petitioners were 14 years of age or older at the time they committed the offenses. Petitioners demurred to the complaint, contending that section 707(d) is unconstitutional on a number of grounds. First, petitioners claimed that section 707(d) violates the separation of powers doctrine by vesting in the district attorney the discretion. whether to file specified charges against minors 14 years of age and older in either the juvenile division or the criminal division of the superior court. Petitioners further contended that section 707(d) deprives them of due process of law because the statute does not provide for any hearing to determine whether they are fit for a disposition under the juvenile court law. Petitioners also claimed that section 707(d) violates their right to uniform operation of the laws (Cal. Const., art. IV, §16, subd. (a)) and equal protection of the laws, because it permits two classes of minors charged with the same crime to be treated differently at the discretion of the prosecutor. Furthermore, petitioners asserted that placing minors in prison with adult offenders violates the constitutional prohibitions against cruel and unusual punishment. Finally, petitioners contended that Proposition 21 violates the single-subject rule (Cal. Const., art. II, § 8, subd. (d)), because it addresses at least three assertedly distinct, unrelated subjects: (1) the juvenile justice system, (2) criminal gang activity, and (3) sentencing provisions unrelated to juveniles or gang activity. The superior court overruled the demurrers. The court concluded that section 707(d) does not violate the separation of powers doctrine, because the decision whether to charge crimes lies within the traditional power and discretion of the prosecutor. The superior court also concluded that no due process right to a hearing exists in these circumstances, that the statute does not create any classes in which similarly situated individuals are treated disparately, that Proposition 21 does not violate the prohibitions against cruel and unusual punishment, and that the provisions of the initiative are reasonably related to, and germane to, the main purpose of reducing violent crimes committed by juveniles and gangs. Petitioners Manduley and Rose filed separate petitions for writ of mandate and/or prohibition in the Court of Appeal. They sought an order dismissing the criminal complaint, directing the superior court to certify the matter to the juvenile division of the superior court for the filing of a petition pursuant to section 602, subdivision (a), and precluding their arraignment. The Court of Appeal granted the joint motions of all petitioners to join in both petitions, consolidated the petitions, stayed the arraignments of petitioners, and issued an order to show cause why the relief sought by petitioners should not be granted. Petitioners raised in the Court of Appeal all the issues raised in the superior court, except for the claim based upon the prohibitions against cruel and unusual punishment. In a divided decision, the Court of Appeal held that section 707(d) violates the separation of powers doctrine by conferring upon the prosecutor the discretion to determine which of two legislatively authorized sentencing schemes is available to the court. The majority briefly discussed and expressed doubt regarding the merits of petitioners’ claims based upon the due process and equal protection clauses, but the Court of Appeal did not decide those issues. The People sought review of the Court of Appeal’s resolution of the separation of powers question. We granted review and specified that the issues to be briefed and argued in this court shall include all issues raised in the Court of Appeal. II We begin our analysis of petitioners’ challenge to section 707(d) by reviewing relevant provisions of the juvenile court law and then describing the pertinent changes effected by Proposition 21. The law apart from the provisions of Proposition 21 provides that except as otherwise specified by statute, any individual less than 18 years of age who violates the criminal law comes within the jurisdiction of the juvenile court, which may adjudge such an individual a ward of the court. (§ 602, subd. (a).) A minor accused of a crime is subject to the juvenile court system, rather than the criminal court system, unless the minor is determined to be unfit for treatment under the juvenile court law or is accused of certain serious crimes. For example, when a petition is filed alleging that a minor 16 years of age or older has violated the criminal law and should be adjudged a ward of the juvenile court, the minor generally is subject to the juvenile court law unless the court concludes, upon the motion of the prosecutor and after an investigation and report by a probation officer, that the minor would not be amenable to the care, treatment, and training program available through the facilities of the juvenile court. (§ 707, subd. (a)(1).) In assessing the minor’s fitness for treatment under the juvenile court law, the court considers the minor’s degree of criminal sophistication, whether the minor can be rehabilitated prior to the expiration of the juvenile court’s jurisdiction, the minor’s previous delinquent history, the success of previous attempts by the juvenile court to rehabilitate the minor, and the circumstances and gravity of the alleged offense. (Ibid.) A minor 14 years of age or older who is alleged to have committed one of the serious crimes specified in section 707, subdivision (b)—such as murder, robbery, or assault with a firearm—is presumed not to be a fit and proper subject for treatment under the juvenile court law. (§ 707, subds. (b), (c).) At the juvenile court hearing to determine the question of fitness for treatment, a minor accused of such a crime has the burden of rebutting this presumption of unfitness by a preponderance of the evidence. (Cal. Rules of Court, rule 1483(a).) If a minor is declared not to be a fit and proper subject for treatment under the juvenile court law in accordance with the foregoing statutes, the district attorney may file an accusatory pleading against the minor in a court of criminal jurisdiction, and the case then proceeds according to the laws applicable to a criminal proceeding. (§ 707.1, subd. (a).) Before the passage of Proposition 21, certain minors who were 16 years of age or older at the time they committed specified crimes were required to be prosecuted in a court of criminal jurisdiction—without any requirement of a determination by the juvenile court that the minor was unfit for treatment under the juvenile court law. Section 602, former subdivision (b), provided that an individual at least 16 years of age, who previously had been declared a ward of the court for having committed a felony after the age of 14 years, “shall be prosecuted in a court of criminal jurisdiction if he or she is alleged to have committed” any of several enumerated serious offenses, such as first degree murder where the minor personally killed the victim, certain violent sex offenses, and aggravated forms of kidnapping. (Stats. 1999, ch. 996, § 12.2.) When such a prosecution lawfully was initiated in a court of criminal jurisdiction, the individual would be subject to the same sentence as an adult convicted of the identical offense, subject to specified exceptions. (Pen. Code, § 1170.17, subd. (a).) Former section 1732.6 of the Welfare and Institutions Code provided that in a criminal proceeding against a minor, the court retained discretion to sentence the minor to the California Youth Authority (Youth Authority), unless the minor (1) was convicted of a violent or serious felony, as defined by statute (Pen. Code, §§ 667.5, subd. (c), 1192.7, subd. (c)), and (2) received a sentence of life imprisonment, an indeterminate period up to life imprisonment, or a determinate period of years such that the maximum number of years of potential confinement could require incarceration of the minor beyond the age of 25 years. (Stats. 1994, 1st Ex. Sess. 1993-1994, ch. 15, § 1, p. 8575.) In addition, under no circumstances could a minor less than 16 years of age be housed in any facility under the jurisdiction of the Department of Corrections. (Ibid.) Proposition 21 revised the juvenile court law to broaden the circumstances in which minors 14 years of age and older can be prosecuted in the criminal division of the superior court, rather than in juvenile court. Section 707(d), as amended by the initiative, authorizes specified charges against certain minors to be filed directly in a court of criminal jurisdiction, without a judicial determination of unfitness under the juvenile court law. The statute sets forth three situations in which the prosecutor may choose to file an accusatory pleading against a minor in either juvenile court or criminal court: (1) a minor 16 years of age or older is accused of committing one of the violent or serious offenses enumerated in-section 707, subdivision (b) (§ 707(d)(1)); (2) a minor 14 years of age or older is accused of committing certain serious offenses under specified circumstances (§ 707(d)(2)); and (3) a minor 16 years of age or older is accused of committing specified offenses, and the minor previously has been adjudged a ward of the court because of the commission of any felony offense when he or she was 14 years of age or older (§ 707(d)(3)). Where the prosecutor files an accusatory pleading directly in a court of criminal jurisdiction pursuant to section 707(d), at the preliminary hearing the magistrate must determine whether “reasonable cause exists to believe that the minor comes within the provisions of’ the statute (§ 707(d)(4))— e.g., reasonable cause to believe that a minor at least 16 years of age has committed an offense enumerated in section 707, subdivision (b), or that a minor at least 14 years of age has committed such an offense under the circumstances set forth in section 707(d)(2)(C). If such reasonable cause is not established, the case must be transferred to the juvenile court. (§ 707(d)(4).) Section 602, subdivision (b), which specifies circumstances in which a minor must be prosecuted in a court of criminal jurisdiction, also was amended by Proposition 21. The revised statute decreases the juvenile’s minimum age for such mandatory criminal prosecutions from 16 years to 14 years and alters in some respects the list of crimes for which a criminal prosecution is required. In addition, Proposition 21 amended section 1732.6 to broaden the circumstances in which a minor shall not be committed to the Youth Authority. For example, a commitment to the Youth Authority is prohibited where a minor in a criminal action is convicted of an offense described in section 707(d)(1), (2), or (3) and the additional circumstances enumerated in those subdivisions are found true by the trier of fact. (§ 1732.6, subd. (b)(2).) As was provided prior to the passage of Proposition 21, however, minors less than 16 years of age shall not be housed in any facility under the jurisdiction of the Department of Corrections. (§ 1732.6, subd. (c).) Among the changes effected by Proposition 21, petitioners challenge only the aspect of section 707(d) that confers upon the prosecutor the discretion to file certain charges against specified minors directly in criminal court, without any judicial determination that the minor is unfit for a juvenile court disposition. We proceed to consider petitioners’ various constitutional claims that section 707(d) is invalid. HI Petitioners first contend that section 707(d) violates the separation of powers doctrine by vesting in the prosecutor the authority to make a decision—whether to initiate a proceeding in criminal court or juvenile court—that ultimately dictates whether minors charged with certain offenses, upon conviction, shall be sentenced under the criminal law or receive a disposition under the juvenile court law. The exercise of such authority by the executive branch, petitioners contend, invades the exclusive power of the judiciary to determine the appropriate sentence for individuals who commit criminal offenses. Petitioners’ contention is based upon article III, section 3, of the California Constitution, which states: “The powers of state government are legislative, executive, and judicial. Persons charged with the exercise of one power may not exercise either of the others except as permitted by this Constitution.” The majority of the Court of Appeal agreed with petitioners that section 707(d) violates the separation of powers doctrine. The majority reasoned that resolution of this question depends upon whether the district attorney’s choice between filing a petition in juvenile court or an accusatory pleading in criminal court is a charging decision properly allocated to the executive branch, or instead is a sentencing decision properly allocated to the judicial branch. According to the majority, “the fundamental nature of the decision given to district attorneys under section 707(d) is a decision that the adult sentencing scheme rather than the juvenile court dispositional scheme must be imposed if the juvenile is found guilty of the charged offenses.” Section 707(d), the majority held, confers upon the prosecutor “the power to preemptively veto a court’s sentencing discretion” and therefore violates separation of powers principles. The dissent in the Court of Appeal, on the other hand, stated that prosecutors traditionally have possessed great discretion, largely unsupervised by the judiciary, to determine what charges to file against an individual, or whether to file charges at all. The dissent observed that a prosecutor’s decision pursuant to section 707(d) whether to file charges in juvenile or criminal court is made before charges have been filed; therefore, the prosecutor exercises no veto over any judicial decision made after the proceeding is commenced. Because, in the dissent’s view, the Legislature (or the voters through the initiative power) could abolish the juvenile justice system completely, or deny access to that system to juveniles of a certain age charged with certain crimes, the dissent concluded that section 707(d) properly could “take a more moderate approach” and delegate to the executive branch the discretion to determine where to file—in juvenile court or criminal court—charges against juveniles of a certain age accused of particular crimes. In this court, the People adopt a position similar to that reflected in the dissent in the Court of Appeal. We believe that the majority of the Court of Appeal adopted an unduly restrictive view of the scope of the executive power traditionally vested in prosecutors to decide what charges shall be alleged, and against whom charges shall be brought. This broad power to charge crimes extends to selecting the forum, among those designated by statute, in which charges shall be filed. Contrary to the majority of the Court of Appeal, the circumstance that such a charging decision may affect the sentencing alternatives available to the court does not establish that the court’s power improperly has been usurped by the prosecutor. “ ‘[Sjubject to the constitutional prohibition against cruel and unusual punishment, the power to define crimes and fix penalties is vested exclusively in the legislative branch.’ [Citations.]” (People v. Superior Court (Romero) (1996) 13 Cal.4th 497, 516 [53 Cal.Rptr.2d 789, 917 P.2d 628] (Romero).) “[T]he power of the people through the statutory initiative is coextensive with the power of the Legislature.” (Legislature v. Deukmejian (1983) 34 Cal.3d 658, 675 [194 Cal.Rptr. 781, 669 P.2d 17].) “[T]he prosecuting authorities, exercising executive functions, ordinarily have the sole discretion to determine whom to charge with public offenses and what charges to bring. [Citations.] This prosecutorial discretion to choose, for each particular case, the actual charges from among those potentially available arises from ‘ “the complex considerations necessary for the effective and efficient administration of law enforcement.” ’ [Citations.] The prosecution’s authority in this regard is founded, among other things, on the principle of separation of powers, and generally is not subject to supervision by the judicial branch. [Citations.]” (People v. Birks (1998) 19 Cal.4th 108, 134 [77 Cal.Rptr.2d 848, 960 P.2d 1073].) “When the decision to prosecute has been made, the process which leads to acquittal or to sentencing is fundamentally judicial in nature.” (People v. Tenorio (1970) 3 Cal.3d 89, 94 [89 Cal.Rptr. 249, 473 P.2d 993].) The judicial power to choose a particular sentencing option, however, may be eliminated by the Legislature and the electorate. (Romero, supra, 13 Cal.4th at p. 516.) Petitioners contend that the legislative branch unconstitutionally has conferred upon the executive branch (that is, the prosecutor) an exclusively judicial function of choosing the appropriate dispositions for certain minors convicted of specified crimes. Several decisions of this court have addressed similar claims. As we shall explain, these decisions establish that the separation of powers doctrine prohibits the legislative branch from granting prosecutors the authority, after charges have been filed, to control the legislatively specified sentencing choices available to a court. A statute conferring upon prosecutors the discretion to make certain decisions before the filing of charges, on the other hand, is not invalid simply because the prosecutor’s exercise of such charging discretion necessarily affects the dispositional options available to the court. Rather, such a result generally is merely incidental to the exercise of the executive function—the traditional power of the prosecutor to charge crimes. Because section 707(d) does not confer upon the prosecutor any authority to interfere with the court’s choice of legislatively specified sentencing alternatives after an action has been commenced pursuant to that statute, we conclude that section 707(d) does not violate the separation of powers doctrine. We reached a similar conclusion in Davis v. Municipal Court (1988) 46 Cal.3d 64 [249 Cal.Rptr. 300, 757 P.2d 11] (Davis). In that case, we considered a constitutional challenge to a local diversion program that conferred upon the district attorney the authority to decide, before charges were filed, whether a defendant would be eligible for pretrial diversion. Eligibility for the diversion program was limited to individuals charged with a misdemeanor offense. Thus, if an offense could be charged as either a misdemeanor or a felony, the prosecutor’s decision to charge such a “wobbler” as a felony precluded diversion, even if the court subsequently exercised its discretion to reduce the felony charge to a misdemeanor. The defendant in Davis contended that conditioning eligibility for diversion upon the prosecutor’s decision to charge a wobbler as a misdemeanor improperly infringed upon the judicial power to make the ultimate determination whether a particular defendant should be diverted. We rejected the contention that this aspect of the diversion program violated the separation of powers doctrine. Our decision in Davis explained: “It is true, of course, that a prosecutor’s exercise of discretion to charge a defendant with a felony rather than a misdemeanor when the facts of the case would support either charge will frequently have a variety of effects on the ultimate judicial disposition of the matter. A prosecutor’s charging decision may, for example, determine whether a defendant is convicted of an offense for which probation may not be granted, or for which a specific punishment is mandated. Those familiar consequences of the charging decision have, however, never been viewed as converting a prosecutor’s exercise of his traditional charging discretion into a violation of the separation-of-powers doctrine.” (Davis, supra, 46 Cal.3d at p. 82.) In Davis, supra, 46 Cal.3d at pages 81-86, we distinguished a line of decisions that invalidated statutory provisions purporting to give a prosecutor the right to veto decisions made by a court after criminal charges had been filed. (E.g., People v. Superior Court (On Tai Ho) (1974) 11 Cal.3d 59 [113 Cal.Rptr. 21, 520 P.2d 405] (On Tai Ho) [district attorney could not disapprove trial court’s decision, following a hearing, to grant diversion]; Esteybar v. Municipal Court (1971) 5 Cal.3d 119 [95 Cal.Rptr. 524, 485 P.2d 1140] [district attorney could not veto magistrate’s decision to reduce a wobbler to a misdemeanor]; People v. Tenorio, supra, 3 Cal.3d 89 [district attorney could not preclude trial court from exercising discretion to strike an allegation of a prior conviction for the purpose of sentencing].) Such decisions are based upon the principle that once the decision to prosecute has been made, the disposition of the matter is fundamentally judicial in nature. A judge wishing to exercise judicial power at the judicial stage of a proceeding never should be required to “ ‘bargain with the prosecutor’ ” before doing so. (Davis, supra, 46 Cal.3d at p. 83.) Charging decisions made before the jurisdiction of a court is invoked and before a judicial proceeding is initiated, on the other hand, involve purely prosecutorial functions and do not limit judicial power. (Id. at p. 86.) This court recently reiterated these principles when we construed a provision of the “Three Strikes” law (Pen. Code, § 667, subd. (f)) not to require the prosecutor’s consent before a trial court could exercise its authority at sentencing to strike a prior-felony-conviction allegation pursuant to Penal Code section 1385. (Romero, supra, 13 Cal.4th at pp. 509-517.) Like the decision whether to charge a wobbler as a misdemeanor, considered in Davis, supra, 46 Cal.3d 64, a prosecutor’s decision pursuant to section 707(d) whether to file a wardship petition in juvenile court or an accusatory pleading in criminal court is made before the jurisdiction of the court is invoked. Although a decision to file charges directly in criminal court might preclude a juvenile court disposition, such a decision—like the prosecutor’s decision in Davis—constitutes an aspect of traditional prosecutorial charging discretion and does not intrude upon the judicial function. Petitioners concede that the legislative branch possesses the power to require that particular charges against certain minors always be initiated in criminal court (§ 602, subd. (b)), and to preclude juvenile dispositions for certain minors convicted of specified offenses (§ 1732.6). (See In re Jose H. (2000) 77 Cal.App.4th 1090, 1099-1100 [92 Cal.Rptr.2d 228].) Petitioners assert, however, that where the juvenile court law provides for the possibility of a juvenile court disposition for a particular minor, the decision whether the minor ultimately receives such a disposition is exclusively a judicial function and cannot be made by the prosecutor. A consideration of the statutory changes effected by Proposition 21, however, establishes that the legislative branch has eliminated the judicial power upon which petitioners base their claim. It is true that, prior to the enactment of section 707(d), section 707 provided that the juvenile court, after a hearing, made the decision whether certain minors charged with particular offenses were fit for treatment under the juvenile court law or instead could be charged and sentenced in criminal court. (See Edsel P. v. Superior Court (1985) 165 Cal.App.3d 763, 786 [211 Cal.Rptr. 869] [fitness determination constitutes a judicial function].) Now, however, with regard to minors within the scope of section 707(d), the statute confers upon the prosecutor the discretion to determine whether accusations of criminal conduct against the minor should be filed in the juvenile court or criminal court. If the prosecutor initiates a proceeding in criminal court, and the circumstances specified in section 707(d) are found to be true, the court generally is precluded by statute from ordering a juvenile disposition. (Welf. & Inst. Code, § 1732.6, subd. (b)(2); see Pen. Code, §§ 1170.17, 1170.19.) The prosecutor’s discretionary charging decision pursuant to section 707(d), which thus can limit the dispositional alternatives available to the court, is no different from the numerous prefiling decisions made by prosecutors (e.g., whether to charge a wobbler as a felony, or whether to charge a particular defendant with assault, assault with a deadly weapon, or another form of aggravated assault, or whether to charge manslaughter or murder, or whether to allege facts that would preclude probation eligibility [Pen. Code, § 1203.06 et seq.]) that limit the dispositions available to the court after charges have been filed. Conferring such authority upon the prosecutor does not limit the judicial power, after charges have been filed, to choose among the dispositional alternatives specified by the legislative branch. The voters, through the enactment of Proposition 21, have determined that the judiciary shall not make the determination regarding a minor’s fitness for a juvenile disposition where the prosecutor initiates a criminal action pursuant to section 707(d). Contrary to the majority of the Court of Appeal, the circumstance that a fitness determination for minors accused of crimes within the scope of section 707(d) formerly was made by the court after a judicial hearing does not establish that granting the prosecutor discretion whether to file charges directly in criminal court invades the judicial prerogative. The Court of Appeal reasoned that, absent section 707(d), the determination of whether the juvenile or criminal sentencing scheme will apply “requires a particularized evidentiary hearing to adjudicate the individual juvenile’s fitness or suitability for juvenile court treatment, and . . . these adjudicatory functions are essentially judicial in nature.” Therefore, the court determined, the decision regarding which dispositional scheme applies “is adjudicatory in nature, and . . . section 707(d) allocates a judicial power and function to the district attorney in violation of separation of powers principles.” The Court of Appeal majority’s analysis misapprehends the purpose and scope of the separation of powers doctrine. The charging authority implicated by section 707(d) constitutes an exclusive executive function, generally reviewable by the judicial branch only for certain constitutionally impermissible factors, such as discriminatory prosecution. (People v. Superior Court (Alvarez) (1997) 14 Cal.4th 968, 976 [60 Cal.Rptr.2d 93, 928 P.2d 1171].) “ ‘The action of a district attorney in filing an information is not in any way an exercise of a judicial power or function.’ [Citation.]” {Ibid.) The circumstance that a charging decision pursuant to section 707(d) can affect judicial functions, after charges have been filed, does not. result in a violation of the separation of powers doctrine. The majority of the Court of Appeal also erred in equating the prosecutor’s decision pursuant to section 707(d) with the fitness determination made by the juvenile court. In circumstances in which 707(d) applies, the statute dispenses with the requirement of “a particularized evidentiary hearing to adjudicate the individual juvenile’s fitness or suitability for juvenile court treatment,” which the Court of Appeal deemed to be an essential adjudicatory function that could not be delegated to the prosecutor. For example, where the prosecutor accuses a minor 16 years of age or older of committing an offense enumerated in section 707, subdivision (b), the prosecutor possesses discretion to file an accusatory pleading in criminal court. (§ 707(d)(1).) In making the decision whether to file a petition in juvenile court or a pleading in criminal court, the district attorney might consider circumstances ordinarily at issue in a fitness hearing (see § 707, subd. (a)(1)), but section 707(d) does not require the prosecutor to do so. In this situation, nothing in the juvenile court law requires or authorizes an evidentiary fitness hearing or any other judicial determination of fitness—other than a finding at the preliminary hearing that reasonable cause exists to believe that the minor has committed an offense described in section 707(d) under the circumstances set forth therein. Thus, section 707(d) grants the district attorney authority to establish and apply the criteria that guide his or her decision whether to file an accusatory pleading in criminal court. Such power is well within the district attorney’s traditional executive authority. (Davis, supra, 46 Cal.3d at pp. 77-78.) Furthermore, the primary purpose of the separation of powers doctrine “is to prevent the combination in the hands of a single person or group of the basic or fundamental powers of government.” (Parker v. Riley (1941) 18 Cal.2d 83, 89 [113 P.2d 873, 134 A.L.R. 1405].) “The doctrine has not been interpreted as requiring the rigid classification of all the incidental activities of government, with the result that once a technique or method of procedure is associated with a particular branch of the government, it can never be used thereafter by another.” (Id. at p. 90) The separation of powers doctrine “recognizes that the three branches of government are interdependent, and it permits actions of one branch that may ‘significantly affect those of another branch.’ [Citation.]” (Carmel Valley Fire Protection Dist. v. State of California (2001) 25 Cal.4th 287, 298 [105 Cal.Rptr.2d 636, 20 P.3d 533].) The doctrine “ ‘is not intended to prohibit one branch from taking action properly within its sphere that has the incidental effect of duplicating a function or procedure delegated to another branch.’ [Citation.]” (Ibid.) The decision whether a minor is to be tried in the juvenile or the criminal division of the superior court, even before the passage of Proposition 21, has not been considered to constitute an exclusively judicial function. For example, if a prosecutor decides to charge a minor at least 14 years of age with certain serious crimes, such as murder with special circumstances when the minor personally killed the victim, the minor must be prosecuted in a court of criminal jurisdiction. (§ 602, subd. (b).) If, on the other hand, the prosecutor chooses to charge the same minor with voluntary manslaughter, the juvenile court, upon the motion of the prosecutor, must conduct a fitness hearing to determine whether the minor should be the subject of a juvenile court proceeding or be tried in criminal court. (§ 707, subd. (c).) In this situation, the Legislature’s specification of crimes in section 602, together with the prosecutor’s exercise of discretion whether to charge a crime specified in that statute, dictates whether the juvenile court will be afforded an opportunity to determine whether the minor is fit for a juvenile court disposition. Similarly, the prosecutor’s decision whether to file certain charges directly in criminal court pursuant to section 707(d), when the circumstances enumerated in that provision are present, might control whether a juvenile disposition will be available to the court in such a proceeding. The prosecutor does not usurp any fundamental judicial power in exercising such discretion, even though the court in other situations is authorized to decide whether a minor is fit for a disposition in juvenile court. The circumstance that a fitness determination is one that properly could be made by the judicial branch, or that historically has been made by the judicial branch, does not alone invalidate a statute granting the executive branch the authority to make an analogous determination that has the same effect as a decision regarding fitness. (See Carmel Valley Fire Protection Dist. v. State of California, supra, 25 Cal.4th 287, 300-301 [separation of powers doctrine does not preclude the Legislature from exercising authority over a matter that could have been undertaken by the executive branch]; In re Attorney Discipline System (1998) 19 Cal.4th 582, 596, 602 [79 Cal.Rptr.2d 836, 967 P.2d 49] [separation of powers doctrine does not bar the judicial branch from undertaking a function historically performed by the Legislature].) Petitioners acknowledge that determining an individual’s eligibility for a particular sentencing alternative is not exclusively a judicial power, and that this power properly may be exercised by the prosecutor or the Legislature. They contend, however, that a prosecutor’s decision whether a particular minor is to be charged in criminal court instead determines suitability for a sentencing alternative, and that such a determination is solely a judicial power. Petitioners rely upon On Tai Ho, supra, 11 Cal.3d 59, and Sledge v. Superior Court (1974) 11 Cal.3d 70 [113 Cal.Rptr. 28, 520 P.2d 412] (Sledge), companion cases in which this court considered a pretrial diversion program for defendants charged with certain narcotics offenses. Under the statutory scheme at issue in those cases, the prosecutor conducted a preliminary screening to determine whether a defendant met certain minimum standards of eligibility specified by statute. If it appeared that the defendant was eligible for diversion, the court conducted a hearing and decided whether to divert the defendant into a rehabilitation program. (On Tai Ho, supra, 11 Cal.3d at pp. 62-63.) In On Tai Ho, supra, 11 Cal.3d 59, we held that a statutory provision purporting to subject the court’s diversion decision to a prosecutorial veto violated the separation of powers doctrine, because the decision whether to divert was an exercise of judicial power. Our opinion emphasized that this decision was made after the jurisdiction of the court had been invoked, that the diversion hearing mandated by statute was a judicial proceeding, and that the statute vested in the court the power to weigh the evidence and make a determination as to the appropriate disposition. In Sledge, supra, 11 Cal.3d 70, we held that the district attorney’s preliminary determination of eligibility for the program was not a judicial act and therefore did not violate the separation of powers doctrine. Our decision relied upon the circumstances that the information required to determine eligibility was in the possession of the district attorney rather than the court, that the statute specified which facts were material and relevant to eligibility and did not confer upon the prosecutor any power to weigh the effect of those facts, and that the prosecutor’s determination that there was evidence rendering a defendant ineligible for diversion could be reviewed on appeal from any conviction. Petitioners contend that the district attorney’s decision pursuant to section 707(d) to prosecute a minor in criminal court is more akin to an unconstitutional prosecutorial veto of a judicial sentencing decision, as in On Tai Ho, supra, 11 Cal.3d 59, than to the eligibility determination upheld in Sledge, supra, 11 Cal.3d 70. They distinguish, on the following grounds, a decision made pursuant to section 707(d) from the eligibility decision in Sledge: (1) section 707(d) does not specify any eligibility criteria; (2) information regarding amenability to a juvenile court disposition is uniquely within the possession of the minor rather than the prosecutor; (3) no judicial hearing is available to evaluate the minor’s suitability for a juvenile court disposition; and (4) no record is created to protect the right to judicial review. Any distinctions between the prosecutor’s authority at issue in Sledge, supra, 11 Cal.3d 70, and that in the present case, however, do not establish that the prosecutor’s exercise of discretion pursuant to section 707(d) usurps an exclusively judicial power. First, as in Davis, supra, 46 Cal.3d at pages 77-78, the legislative branch properly has conferred upon the prosecutor the authority to establish the criteria guiding his or her decision whether to file an action in criminal court pursuant to section 707(d), rather than specifying such criteria by statute as in Sledge. Second, contrary to petitioners’ assertion, information relevant to the prosecutor’s decision, such as the minor’s prior criminal history and evidence of the minor’s current criminal conduct, is within the possession of the prosecutor. Third, no judicial hearing is available regarding amenability for a particular disposition because, unlike the statute considered in Sledge, section 707(d) does not provide for such a hearing or a judicial determination of fitness. Therefore, even if a prosecutor weighs the effect of relevant evidence in reaching a decision, he or she does not interfere with the authority of the court. Finally, section 707(d) does provide for a judicial determination, after the charging decision is made, to ensure that the minor meets the statutory criteria set forth in section 707(d). There is no judicial “review” of the prosecutor’s exercise of discretion to file charges in criminal court against minors who come within the scope of section 707(d), because just as with other instances of the traditional charging power of the prosecutor, the statute vests in the prosecutor the power both to establish and to apply the criteria guiding that decision. For these reasons, a prosecutor’s decision to file charges against a minor in criminal court pursuant to section 707(d) is not analogous to a prosecutor’s veto of a court’s legislatively authorized determination, after a judicial hearing, of a defendant’s suitability for a particular disposition, and such a decision does not usurp a power possessed solely by the judicial branch. Petitioners further characterize the prosecutor’s decision pursuant to section 707(d) as the selection of the “jurisdiction with the most ‘appropriate’ sentencing scheme” for a particular defendant, and they attempt to contrast such a decision with a prosecutor’s well-established authority to select which crime to charge. As established above, however, the decision to charge a minor with a particular crime, like a decision pursuant to section 707(d) to file charges in criminal court, also can eliminate the juvenile court’s jurisdiction over the matter and dictate the sentencing scheme that will apply upon conviction, and petitioners admit that the former decision properly can be exercised by the prosecutor. Inasmuch as petitioners concede that the Legislature possesses the authority to eliminate entirely the jurisdiction of the juvenile court and preclude juvenile court dispositions with regard to all minors who come within the scope of section 707(d), a statute conferring upon the prosecutor the discretion, before a judicial proceeding has been commenced, to charge some of these minors in criminal court does not usurp an exclusively judicial authority. Moreover, the Legislature in other contexts has authorized the People to pursue allegations of criminal conduct in alternative fora, sometimes with different penalties. For example, before unification of the California trial courts, the prosecutor’s decision whether to charge an offense as a misdemeanor or a felony could determine whether the matter would be tried in municipal court or superior court. (See Pen. Code, § 1462, subd. (a) [municipal court had jurisdiction in cases involving misdemeanors].) In addition, where criminal conduct constitutes a violation of both federal law and state law, and federal and California courts have concurrent jurisdiction, the district attorney possesses discretion to consent to proceedings in federal court or to request that the federal authorities relinquish a federal prisoner to the state for prosecution. (4 Witkin & Epstein, Cal. Criminal Law (3d ed. 2000) Jurisdiction and Venue, § 5, p. 91.) Furthermore, where the Legislature has specified more than one location in which venue is proper, prosecutors may choose the forum in which to file criminal charges. (See Pen. Code, §§ 778-795.) Finally, the Legislature has conferred upon district attorneys the discretion to seek either civil or criminal sanctions for certain illegal conduct. For example, when confronted with gang-related crime, the prosecutor can decide to charge individual gang members in criminal court for the offense of participation in a criminal street gang (Pen. Code, § 186.22) or instead can file a civil action in superior court to abate gang activity (id.., § 186.22a). (See also, e.g., Bus. & Prof. Code, § 16754 [authorizing district attorney to initiate civil actions or criminal proceedings for violations of the Cartwright Act]; Health & Saf. Code, §§ 25189-25191 [authorizing both criminal and civil penalties for the illegal disposal of hazardous waste].) Therefore, the circumstance that a prosecutor’s charging decision pursuant to section 707(d) determines the forum in which charges of criminal conduct against minors are adjudicated, or limits the sanctions available to the court, does not mean that the prosecutor exercises any judicial power when making such a decision. We also find no merit in petitioners’ contention that the absence of statutory criteria guiding the prosecutor’s decision pursuant to section 707(d) results in an unconstitutional delegation of the Legislature’s exclusive authority to fix penalties for crimes. As we have explained, most prosecutorial charging decisions can circumscribe the sentencing options available to the court, and such decisions never have been considered to be analogous to fixing penalties for charged crimes or to require legislative guidelines governing the exercise of prosecutorial discretion. The minimum standards governing the prosecutor’s discretion whether to file charges against a minor in criminal court are those set forth in section 707(d). In these circumstances, a prosecutor’s charging decision that results in a greater or lesser penalty does not constitute an impermissible delegation of legislative authority. (Davis, supra, 46 Cal.3d at pp. 88-89.) Similarly, we have rejected the claim that, in capital cases, the prosecutor is required to abide by certain nonarbitrary standards in making the initial decision whether to allege special circumstances and whether to seek the death penalty. (People v. Lucas (1995) 12 Cal.4th 415, 478 [48 Cal.Rptr.2d 525, 907 P.2d 373].) “When he [or she] acts under such a law, and ‘[a]bsent a persuasive showing to the contrary, we must presume that the district attorney’s decisions were legitimately founded on the complex considerations necessary for the effective and efficient administration of law enforcement. [Citation.]’ [Citation.]” (People v. Keenan (1988) 46 Cal.3d 478, 506 [250 Cal.Rptr. 550, 758 P.2d 1081].) These principles apply with equal force to a prosecutor’s decision whether to file a criminal action pursuant to section 707(d). The statute does not result in an improper delegation of legislative power. Courts in several other jurisdictions have rejected similar challenges, based upon the separation of powers doctrine, to statutes conferring upon prosecutors the authority to decide whether to file charges against minors in criminal court rather than juvenile court. (E.g., People v. Thorpe (Colo. 1982) 641 P.2d 935, 938-940; State v. Cain (Fla. 1980) 381 So.2d 1361, 1367-1368; Bishop v. State (1995) 265 Ga. 821 [462 S.E.2d 716, 717]; People v. Conat (1999) 238 Mich.App. 134 [605 N.W.2d 49, 56-59]; Jones v. State (1982) 1982 Okla. 196 [654 P.2d 1080, 1082-1083]; Hansen v. State (Wyo. 1995) 904 P.2d 811, 819-820.) The Court of Appeal distinguished some of these decisions on the ground that the statutory schemes there at issue authorized the criminal court to remand the case to the juvenile system after the action had been commenced, thus preserving the authority of the judiciary. For the most part, however, this circumstance was not important to the analysis of these decisions, which in upholding the statutes relied primarily upon the scope of the prosecutor’s discretionary charging power. Furthermore, the statutory scheme considered in People v. Conat, supra, 605 N.W.2d 49, did not include a provision for the court to remand the proceeding to the juvenile court. These decisions provide additional support for our conclusion that the prosecutor’s exercise of discretion pursuant to section 707(d) whether to file an accusatory pleading in criminal court is within the scope of the executive power and does not violate the separation of powers doctrine. Having concluded that the Court of Appeal erred in holding section 707(d) unconstitutional under the separation of powers doctrine, we shall resolve petitioners’ remaining constitutional challenges to the statute. IV Petitioners further challenge section 707(d) on the ground that it deprives them of due process of law as guaranteed by the federal and California Constitutions. (U.S. Const., 5th & 14th Amends.; Cal. Const., art. I, § 7, subd. (a).) According to petitioners, a minor accused of criminal conduct possesses a statutory right to be subject to the jurisdiction of the juvenile court. Before a prosecutor may deprive a minor of that right by filing an action in criminal court pursuant to section 707(d), petitioners contend, the minor is entitled to a hearing to determine, pursuant to established criteria, whether he or she is amenable for a juvenile court disposition. Because section 707(d) neither provides for such a hearing nor sets forth criteria guiding the prosecutor’s exercise of discretion, petitioners claim that the statute violates minimum constitutional standards of procedural fairness. The premise of petitioners’ claim is false, however, because minors who commit crimes under the circumstances set forth in section 707(d) do not possess any statutory right to be subject to the jurisdiction of the juvenile court. Although the juvenile court has jurisdiction over minors accused of most crimes (§ 602), under the statutory provisions adopted by the enactment of Proposition 21, the criminal court also has jurisdiction over those minors who come within the scope of section 707(d), when the prosecutor files charges in that court. (§ 707(d)(4).) In these circumstances, when governing statutes provide that the juvenile court and the criminal court have concurrent jurisdiction, minors who come within the scope of section 707(d) do not possess any right to be placed under the jurisdiction of the juvenile court before the prosecutor initiates a proceeding accusing them of a crime. Thus, the asserted interest that petitioners seek to protect through a judicial hearing does not exist. Statutory provisions that predate the adoption of Proposition 21 cannot properly be interpreted to afford minors a statutory right that is inconsistent with the language and purpose of this legislative measure. Proposition 21 neglected to amend explicitly the jurisdictional provisions of section 603 to clarify that a criminal charge against a minor may be filed directly in a court of criminal jurisdiction pursuant to either the preexisting provisions of section 707.01 (as already provided in section 603, subdivision (b)) or the newly adopted provisions of section 707(d). In light of established principles of statutory construction, however, it is clear that because the provisions of section 707(d) are more recently enacted and more specific than the provisions of section 603, it is appropriate to harmonize the two statutes to effectuate the purpose of this aspect of Proposition 21. (See Lake v. Reed (1997) 16 Cal.4th 448, 464 [65 Cal.Rptr.2d 860, 940 P.2d 311]; DeVita v. County of Napa (1995) 9 Cal.4th 763, 778 [38 Cal.Rptr.2d 699, 889 P.2d 1019]; Kaiser v. Hopkins (1936) 6 Cal.2d 537, 538 [58 P.2d 1278].) Accordingly, section 707(d) properly must be interpreted as creating an additional statutory exception to the general rule, reflected in section 603, subdivision (a), that criminal charges against minors ordinarily must be filed initially in juvenile court. For similar reasons, an isolated phrase contained in section 707(d)(6) cannot be interpreted reasonably to create a right or expectation that a minor may be tried in criminal court only after a determination of unfitness equivalent to that made by the juvenile court pursuant to other subdivisions of section 707. Section 707(d)(6) states: “If, pursuant to this subdivision, the minor is found to be not a fit and proper subject for juvenile court treatment and is tried in a court of criminal jurisdiction and found guilty by the trier of fact, the judge may commit the minor to the Youth Authority in lieu of sentencing the minor to the state prison,” except as otherwise provided by statute. Language identical to that in section 707(d)(6) also was added by Proposition 21 to section 707, subdivisions (a) and (c), which require the juvenile court to make a fitness determination based upon an evaluation of specified criteria concerning the minor. Read in context, the obvious purpose of this language is to make clear that minors whose cases are tried in criminal court under any provision of section 707, including section 707(d), may be committed to the Youth Authority instead of state prison (subject to the exceptions specified in section 1732.6). In view of the explicit language of subdivision (d)(1), (2), and (3) of section 707, which authorizes prosecutors to file actions in criminal court without any reference to a fitness determination, and the purpose of these provisions as reflected in the ballot materials, section 707(d) as a whole cannot be construed reasonably as placing a substantive “unfitness” limitation upon the prosecutor’s discretion and thereby creating a liberty interest in a minor not to be charged in criminal court without such a finding. Several amici curiae supporting petitioners contend that juvenile offenders possess a constitutionally protected liberty interest in remaining in the juvenile court system, and that this interest precludes the prosecutor from filing charges against minors in criminal court without first providing notice and a hearing. The authority upon which amici curiae rely, however, found liberty interests arising from statutes that created an expectation that adverse action by the state would occur only upon the occurrence of certain conditions. (E.g., Vitek v. Jones (1980) 445 U.S. 480, 488-491 [100 S.Ct. 1254, 1261-1263, 63 L.Ed.2d 552] [transfer of prisoner to mental hospital permitted only after a finding of mental illness].) Section 707(d), in contrast, eliminates any expectation that a minor who commits an offense under the circumstances specified therein will be transferred to criminal court only upon an adverse fitness determination by the court. The predicate for filing charges in criminal court pursuant to section 707(d) is a determination by the prosecutor that the circumstances set forth in that statute are present. To the extent this provision creates a protected liberty interest that minors will be subject to the jurisdiction of the criminal court only upon the occurrence of the conditions set forth therein, the statute does require a judicial determination, at the preliminary hearing, “that reasonable cause exists to believe that the minor comes within the provisions” of the statute. (§ 707(d)(4).) Contrary to the contention of amici curiae, such a minor possesses no other protected interest in remaining in the juvenile court system. (Hicks v. Superior Court (1995) 36 Cal.App.4th 1649, 1658 [43 Cal.Rptr.2d 269] [minors possess no constitutional or fundamental right to trial in juvenile court]; accord, State v. Angel C. (1998) 245 Conn. 93 [715 A.2d 652, 659-665] [minors possess no liberty interest in juvenile status where applicable statutes authorize prosecutor to file charges directly in criminal court or to seek a transfer to juvenile court].) Because petitioners do not possess a protected interest in being subject to the jurisdiction of the juvenile court, the authority upon which they rely in support of their claim is distinguishable. In Kent v. United States (1966) 383 U.S. 541 [86 S.Ct. 1045, 16 L.Ed.2d 84] (Kent), the high court considered a statutory scheme conferring upon the juvenile court “ ‘original and exclusive’ ” jurisdiction over a minor accused of committing various crimes. (Id. at p. 556 [86 S.Ct. at p. 1055].) The law authorized the juvenile court to waive its jurisdiction and transfer the matter to criminal court after a “ ‘full investigation,’ ” but no statutory criteria or procedures governed the juvenile court’s determination to waive jurisdiction. (Id. at p. 547 [86 S.Ct. at p. 1050].) The decision in Kent held that the juvenile court violated the minor’s right to due process of law when it transferred the matter to criminal court without conducting a hearing or providing a statement of reasons. The United States Supreme Court explained that the waiver of jurisdiction in this context was a critically important action that determined vitally important statutory rights of the minor, including whether he was entitled to the special rights and immunities ordinarily conferred upon minors under the juvenile court law. Under these circumstances, the high court held, the minor was entitled to a judicial hearing affording “the essentials of due process and fair treatment.” (Id. at p. 562 [86 S.Ct. at p. 1057].) In connection with such a hearing, the minor possessed the right to the effective assistance of counsel, access to the records considered by the juvenile court, and a statement of reasons for the juvenile court’s decision. (Id. at pp. 553-563 [86 S.Ct. at pp. 1053-1058]; see also In re Winnetka V. (1980) 28 Cal.3d 587, 593-595 [169 Cal.Rptr. 713, 620 P.2d 163] [requiring procedural protections in connection with juvenile fitness determinations and dispositional orders made by the court].) Unlike the statute considered in Kent, supra, 383 U.S. 541, California’s juvenile court law does not confer upon the juvenile court original and exclusive jurisdiction over minors accused of crimes under the circumstances set forth in section 707(d). Furthermore, pursuant to section 707(d), neither the juvenile court nor the criminal court renders a decision whether the minor is fit for a juvenile court disposition. Rather, as we have explained, the prosecutor’s charging decision determines which court shall hear the matter. Petitioners nevertheless contend that the procedural protections ordinarily applicable injudicial fitness hearings, and mandated for such hearings by Kent, also must apply to the prosecutor’s exercise of discretion whether to file charges in juvenile court or criminal court. Otherwise, they maintain, decisions determining whether minors a
