*557*532This case presents a narrow question for determination: is Senate Bill No. 1391 (Stats.

*5332018, ch. 1012, § 1) (S.B. 1391) void as an unconstitutional amendment to Welfare and Institutions Code1 section 707 as modified by the Public Safety and Rehabilitation Act of 2016 (Proposition 57)? Petitioner, the People of the State of California,2 filed two petitions for writ of mandate with this court seeking relief from separate orders by respondent Superior Court of Sacramento County refusing to transfer real parties in interest R. Z. and K. L. from juvenile to criminal court for purposes of criminal prosecution based on section 707 as modified by legislative enactment of S.B. 1391. Specifically, petitioner argues S.B. 1391's bar on the transfer of minors under the age of 16 for criminal prosecution as adults is unconstitutional because it does not further the intent and purpose of Proposition 57. We disagree and will deny the petitions.

BACKGROUND

The underlying conduct that brings the minor real parties in interest within the jurisdiction of either the juvenile court or the criminal court is not relevant to resolution of the narrow legal issue before us. Accordingly, we limit our factual and procedural recitation to those matters pertinent to our inquiry.

In early 2016, petitioner charged minor K. L., who was 15 years old at the time of the alleged conduct, by felony criminal complaint of murder, attempted murder, and shooting into an occupied vehicle, with additional allegations that K. L. personally discharged a firearm causing death and great bodily injury and that he committed the crimes for the benefit of, at the direction of, or in association with a criminal street gang. In 2017, following the passage of Proposition 57 by the electorate, the trial court suspended criminal proceedings and certified K. L. to juvenile court for a transfer hearing. Thereafter, in October 2018, the trial court found K. L. unfit for juvenile court and granted petitioner's motion to transfer K. L. to criminal court. However, the trial court stayed that transfer order until January 2019 to determine the applicability and constitutionality of a new legislative enactment -- S.B. 1391.

*558Over petitioner's opposition, on January 10, 2019, the trial court dismissed the motion to transfer K. L. to criminal court, vacated its prior order transferring the minor, and sent the matter to juvenile court.

*534In late 2017, minor R. Z., who was 15 years old at the time of the alleged conduct, was arraigned on a juvenile petition alleging that he came within the jurisdiction of the juvenile court because he committed murder and personally discharged a firearm causing great bodily injury or death in the commission of the homicide. In December 2018, the trial court found R. Z. unfit for juvenile court and granted petitioner's motion transferring R. Z. to criminal court. However, the trial court stayed execution of that order until January 2019 so that it could determine the effect of S.B. 1391 on its order transferring the minor. Over petitioner's opposition, on January 10, 2019, the trial court dismissed the motion to transfer R. Z. to criminal court, vacated its prior order transferring the minor, and sent the matter to juvenile court.

On January 28, 2019, petitioner filed petitions for writ of mandate with this court challenging the trial court's orders directing the proceedings relative to the conduct of K. L. and R. Z. to be conducted in juvenile court. On January 31, 2019, to prevent the attachment of jeopardy prior to resolution of the issue raised by the petitions for writ of mandate (see Gonzalez v. Municipal Court (1973) 32 Cal.App.3d 706, 713-714, 108 Cal.Rptr. 612 ), we stayed the juvenile court proceedings pending our decision on the petitions for writ of mandate. To resolve an issue of statewide importance, we thereafter issued orders to show cause in both matters.

DISCUSSION

Petitioner challenges the constitutionality of S.B. 1391 on the basis that barring criminal prosecution of 14- or 15-year-old minors does not further the purpose and intent of Proposition 57.3 Specifically, petitioner argues that it was the intent of Proposition 57 to specifically authorize criminal prosecution of 14- and 15-year-old minors charged with serious offenses, but to vest the decision whether to transfer the minors to criminal court with a judge instead of a prosecutor. We are not persuaded.

Dictates Of Our Statutory Review

As petitioner's argument asserts that S.B. 1391 is an improper amendment of a voter-approved initiative, we must first clarify when an initiative may be amended by legislative enactment. "The Legislature ... may amend or repeal an initiative statute by another statute that becomes effective only when approved by the electors *559unless the initiative statute permits amendment or repeal without the electors' approval." ( Cal. Const. Art. II, § 10, subd. (c).) Proposition 57 authorizes legislative amendment of its provisions that amended section 707, "so long as such amendments are consistent with and further the intent of this act by a statute that is passed by a majority vote of the members of each house of the Legislature and signed by the Governor." (2016 Voter Guide, § 5, p. 145.) The limited question before us is whether S.B. 1391 is "consistent with and further[s] the intent of" Proposition 57.

In this context, "[w]e 'start[ ] with the presumption that the Legislature acted within its authority' and uphold the validity of the legislative amendment 'if, by any reasonable construction, it can be said that the statute furthers the purposes' of the initiative." ( People v. DeLeon (2017) 3 Cal.5th 640, 651, 220 Cal.Rptr.3d 784, 399 P.3d 13 ; see also Gardner v. Schwarzenegger (2009) 178 Cal.App.4th 1366, 1374, 101 Cal.Rptr.3d 229 ; Foundation for Taxpayer & Consumer Rights v. Garamendi (2005) 132 Cal.App.4th 1354, 1365, 34 Cal.Rptr.3d 354 ["We presume the constitutionality of a legislative act, resolving all doubts in favor of the act, and must uphold the act unless a conflict with a provision of the state or federal Constitution is clear and unquestionable"].) "In identifying the purposes of an initiative, we examine the initiative as a whole, and are guided by, but not limited to, its general statements of purpose. [Citation.] We must give effect to an initiative's specific language, as well as its major and fundamental purposes." ( Gardner , at p. 1374, 101 Cal.Rptr.3d 229.) The limitations on legislative amendment are "strictly construed and may not be given effect as against the general power of the legislature, ' " 'unless such limitations clearly inhibit the act in question. ' " ' " ( Foundation , at p. 1365, 34 Cal.Rptr.3d 354 ; see also Amwest Surety Ins. Co. v. Wilson (1995) 11 Cal.4th 1243, 1255-1256, 48 Cal.Rptr.2d 12, 906 P.2d 1112.) And, as is true of all statutory interpretation, we begin first with the language of the statute, giving its words ordinary meaning, and construing it within the context of the statute and overall statutory scheme as a whole. ( Robert L. v. Superior Court (2003) 30 Cal.4th 894, 900-901, 135 Cal.Rptr.2d 30, 69 P.3d 951.) If the language is ambiguous, we refer to other " ' "indicia" ' " of voter intent, such as the Official Voter Information Guide. ( Ibid. ) We *536may also be guided by the general description of the initiative's purpose offered by its proponents.4 ( *560Proposition 103 Enforcement Project v. Quackenbush (1998) 64 Cal.App.4th 1473, 1490-1491, 76 Cal.Rptr.2d 342.)

A Brief Statutory History

For more than a century, California courts have recognized that proceedings for juveniles charged with crimes are different than for adults accused of crimes. (See Ex Parte Ah Peen (1876) 51 Cal. 280, 281 [explaining the purposes of a proceeding against a 16 year old is "not punishment for offenses done, but reformation and training ... with a view to his future usefulness when he shall have been reclaimed to society, or shall have attained his majority"].) This distinction was incorporated in California's first statutory approach to juvenile law. (See Stats. 1903, ch. 43, §§ 1, 7-8, pp. 44, 46-47 [authorizing placement of child alleged to be delinquent in own home under supervision of probation officer, in state reform school, with some association, society, or corporation, or in a family home, who will care for the child].) It was further encapsulated in the 1961 statutory overhaul to juvenile law, which initiated the now-familiar best interest of the child standard, with a goal of promoting "care and guidance ... as will serve the spiritual, emotional, mental, and physical welfare of the minor and the best interests of the State." (Stats. 1961, ch. 1616, § 502, p. 3460.) With this legislative intent in mind, we turn to a review of the procedural requirements for criminal prosecution of minors.

" 'Historically, a child could be tried in criminal court only after a judicial determination, before jeopardy attached, that he or she was unfit to be dealt *537with under juvenile court law. Since 1975 the procedural requirements for fitness hearings have been established by section 707.' [Citation.] The general rule used to be that '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.' " ( People v. Superior Court (Lara ) (2018) 4 Cal.5th 299, 305, 228 Cal.Rptr.3d 394, 410 P.3d 22.) Indeed, for decades only those minors who were at least 16 years of age at the time of the offense could be transferred to criminal court. (See Hicks v. Superior Court (1995) 36 Cal.App.4th 1649, 1654-1655, 43 Cal.Rptr.2d 269 ; see also Stats. 1961, ch. 1616, §§ 500, 510, 707, pp. 3459, 3462, 3485 [as enacted in 1961, the " 'Juvenile Court Law' " set 16 as a minimum age for transfer to criminal court for prosecution or to state prison for incarceration].) However, in 1994, the Legislature expanded that group to include minors aged 14 or 15 at the time of the offense, for certain charged crimes and with certain limiting circumstances. (Stats. 1994, ch. 453 (AB 560), § 9.5; Hicks , at pp. 1655-1656, 43 Cal.Rptr.2d 269.) At that time, any transfer of a minor was still subject to a judicial determination of unfitness. ( Hicks , at pp. 1656-1657, 43 Cal.Rptr.2d 269 ; see also Manduley v. Superior Court (2002) 27 Cal.4th 537, 548-549, 548-549, 117 Cal.Rptr.2d 168, 41 P.3d 3.)

Then, in 2000, the voters enacted Proposition 21, "the Gang Violence and Juvenile Crime Prevention Act." ( Manduley v. Superior Court, supra , 27 Cal.4th at pp. 544-545, 117 Cal.Rptr.2d 168, 41 P.3d 3.) At that time, "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 *561the juvenile court law." ( Id. at p. 549, 117 Cal.Rptr.2d 168, 41 P.3d 3 ; see also Juan G. v. Superior Court (2012) 209 Cal.App.4th 1480, 1488-1489, 147 Cal.Rptr.3d 816.) Among other things, Proposition 21 extended direct filing in criminal court by the prosecution to those minors aged 14 or 15 years old, who were charged with certain offenses in certain circumstances. ( Manduley , at pp. 549-550, 117 Cal.Rptr.2d 168, 41 P.3d 3.)

"California voters approved Proposition 57, dubbed the Public Safety and Rehabilitation Act of 2016, at the November 2016 general election." ( In re Edwards (2018) 26 Cal.App.5th 1181, 1185, 237 Cal.Rptr.3d 673.) With respect to juveniles, "Proposition 57 changed the procedure again, and largely returned California to the historical rule. 'Among other provisions, Proposition 57 amended the Welfare and Institutions Code so as to eliminate direct filing by prosecutors. Certain categories of minors ... can still be tried in criminal court, but only after a juvenile court judge conducts a transfer hearing to consider various factors such as the minor's maturity, degree of criminal sophistication, prior delinquent history, and whether the minor can be rehabilitated.' " ( People v. Superior Court (Lara ), supra , 4 Cal.5th at p. 305, 228 Cal.Rptr.3d 394, 410 P.3d 22.) Indeed, under Proposition 57, youths aged 16 or older who had committed felonies were eligible for transfer, following a judicial determination of *538fitness for juvenile adjudication, while youths aged 14 or 15 were eligible following a judicial determination only if they had committed certain enumerated serious crimes. (2016 Voter Guide, § 4.2, p. 142.) Courts have noted that the enactment of Proposition 57 reflects a "sea change in penology regarding the relative culpability and rehabilitation possibilities for juvenile offenders" over the 16 years since Proposition 21 was enacted, as reflected in several judicial opinions. ( People v. Vela (2017) 11 Cal.App.5th 68, 75, 218 Cal.Rptr.3d 1, citing Graham v. Florida (2010) 560 U.S. 48, 67, 130 S.Ct. 2011, 2025, [176 L.Ed.2d 825, 840] [a juvenile may not be sentenced to life without the possibility of parole for a nonhomicide offense ] & Miller v. Alabama (2012) 567 U.S. 460, 469-472, 132 S.Ct. 2455, 2462-2464, [183 L.Ed.2d 407, 417-419] [a juvenile may not be sentenced to life without the possibility of parole, even for a homicide, without consideration of youth-related factors in sentencing].)

Then, in 2018, the Legislature enacted S.B. 1391, which further amended section 707 by removing the authority of the prosecutor to seek transfer of a minor who was 14 or 15 years old at the time of committing the offense, unless the minor was not apprehended prior to the end of juvenile court jurisdiction.

III

The Purpose And Intent Of Proposition 57

The uncodified text of Section 2 of Proposition 57, sets forth as its purpose and intent the following: "1. Protect and enhance public safety. [¶] 2. Save money by reducing wasteful spending on prisons. [¶] 3. Prevent federal courts from indiscriminately releasing prisoners. [¶] 4. Stop the revolving door of crime by emphasizing rehabilitation, especially for juveniles. [¶] 5. Require a judge, not a prosecutor, to decide whether juveniles should be tried in adult court." (2016 Voter Guide, § 2, p. 141.) Petitioner argues S.B. 1391 conflicts with Proposition 57's intent to have a juvenile court judge determine whether a 14 or 15 year old should be tried in adult court. If S.B. 1391 contravenes any stated primary purpose of the initiative, it is invalid. ( *562Gardner v. Schwarzenegger, supra , 178 Cal.App.4th at p. 1378, 101 Cal.Rptr.3d 229 ; Foundation for Taxpayer & Consumer Rights v. Garamendi, supra , 132 Cal.App.4th at pp. 1370-1371, 34 Cal.Rptr.3d 354.) Thus, we must ascertain whether, as petitioner urges, it would contravene the intent of Proposition 57 to preclude prosecution of 14 and 15 year olds in adult court. *539It is a stated intent of Proposition 57 that "a judge, not a prosecutor, ... decide whether juveniles should be tried in adult court." As noted above, Proposition 57 amended section 707 to provide that instead of directly filing charges in criminal court, a prosecutor may move for transfer of proceedings to criminal court, and the juvenile court exercises its discretion to determine whether such a transfer is appropriate. (2016 Voter Guide, § 4.2, pp. 142, 144.) S.B. 1391 has not eliminated that procedural scheme but has limited the pool of minors eligible for such a transfer.5 Under S.B. 1391, for minors aged 16 and older, the prosecutor continues to make a motion for transfer of the charged minor, and the juvenile court determines whether the minor should be transferred for criminal prosecution. ( § 707, subd. (a).) So, at least with respect to minors aged 16 and over, there is no conflict between Proposition 57 and S.B. 1391.

The question then becomes whether it was a specific intent of Proposition 57 to permit prosecution of minors aged 14 or 15 in adult court. There is no dispute that by its language, Proposition 57 does permit transfer of minors aged 14 or 15 if they commit certain crimes. (2016 Voter Guide, § 4.2, p. 142.) That is not, however, determinative of whether it was one of the "major and fundamental purposes" of Proposition 57 ( Gardner v. Schwarzenegger, supra , 178 Cal.App.4th at p. 1374, 101 Cal.Rptr.3d 229 ) or that eliminating that possibility is a "clear and unquestionable" conflict with Proposition 57 ( Foundation for Taxpayer & Consumer Rights v. Garamendi, supra , 132 Cal.App.4th at p. 1365, 34 Cal.Rptr.3d 354 ).6

Proposition 57 does not state as its specific intent that minors aged 14 or 15 be subject to prosecution in criminal court. Rather, the language used in the stated purpose of Proposition 57, which petitioner asserts is contravened by S.B. 1391, is to have a "judge, not a prosecutor, ... decide whether juveniles should be tried in adult court." (2016 Voter Guide, § 2, p. 141.) This language does not suggest a focus on retaining the ability to charge juveniles in adult court so much as removing the discretion of district attorneys to make that decision. This interpretation of the language, *540which inherently reduces the number of juveniles tried in adult court, is supported by other explicit statements of intent to "reduc[e] wasteful spending on prisons," "[p]revent federal courts from indiscriminately releasing prisoners," and to *563"emphasiz[e] rehabilitation, especially for juveniles." (2016 Voter Guide, § 2, p. 141.) That said, as the plain language of Proposition 57 is not decisive on the issue, we turn to other indicia to discern the voters' intent on this subject.

With respect to juveniles, the official title and summary for Proposition 57, prepared by the Attorney General and included in the ballot materials provided to the voters, states: "Provides juvenile court judges shall make determination, upon prosecutor motion, whether juveniles age 14 and older should be prosecuted and sentenced as adults for specified offenses." (2016 Voter Guide, p. 54.) The summary prepared by the legislative analyst explains that Proposition 57 "changes state law to require that, before youths can be transferred to adult court, they must have a hearing in juvenile court to determine whether they should be transferred. As a result, the only way a youth could be tried in adult court is if the juvenile court judge in the hearing decides to transfer the youth to adult court. Youths accused of committing certain severe crimes would no longer automatically be tried in adult court and no youth could be tried in adult court based only on the decision of a prosecutor." (2016 Voter Guide, p. 56.) The analysis further expounds that "the measure specifies that prosecutors can only seek transfer hearings for youths accused of (1) committing certain significant crimes ... when they were age 14 or 15 or (2) committing a felony when they were 16 or 17. As a result of these provisions, there would be fewer youths tried in adult court." (Ibid. )

The official argument in favor of Proposition 57 included in the ballot materials notes that Proposition 57 will "focus[ ] resources on keeping dangerous criminals behind bars, while rehabilitating juvenile and adult inmates and saving tens of millions of tax payer dollars." (2016 Voter Guide, p. 58.) Further, it states: "Overcrowded and unconstitutional conditions led the U.S. Supreme Court to order the state to reduce its prison population. Now, without a common sense, long-term solution, we will continue to waste billions and risk a court-ordered release of dangerous prisoners. This is an unacceptable outcome that puts Californians in danger ...." (Ibid. ) Specifically addressing juveniles, the argument in favor claims that Proposition 57 "[r]equires judges instead of prosecutors to decide whether minors should be prosecuted as adults, emphasizing rehabilitation for minors in the juvenile system." (Ibid. ) It explains that "[e]vidence shows that the more *541inmates are rehabilitated, the less likely they are to re-offend. Further evidence shows that minors who remain under juvenile court supervision are less likely to commit new crimes. Prop. 57 focuses on evidence-based rehabilitation and allows a juvenile court judge to decide whether or not a minor should be prosecuted as an adult." (Ibid. )

Taken as a whole, and in the context of juvenile offenders, it appears the intent of Proposition 57 was to reduce the number of youths who would be prosecuted as adults. This appears to be an intent that will further other broader purposes of Proposition 57 to reduce the number of offenders incarcerated in state prisons, and to increase the opportunities for rehabilitation, particularly for juvenile offenders. That Proposition 57 enacted a procedural scheme to remove from the prosecutor and vest in the judiciary the discretion to determine whether a youth should be prosecuted as an adult, and that it stated it was its intent to impose such a transfer of discretionary power, is in accord with these other purposes. Additionally, under the scheme formalized by Proposition 57, the judiciary merely acted as a check on the prosecutor's discretionary decision by ruling on the motions for transfer, it did not independently *564decide which charged youths should be subject to the possibility of transfer. This scheme, and these stated purposes and intent are not contravened by S.B. 1391. Rather, S.B. 1391 furthers the stated purpose and intent of Proposition 57 to have fewer youths removed from the juvenile justice system.

And, while Proposition 57 did continue to permit transfer of 14 and 15 year olds to adult court for prosecution, there is nothing in the language of Proposition 57 or the ballot materials to suggest that it was a specific intent of Proposition 57 to ensure that 14- and 15-year-old juvenile offenders would continue to be subject to adult criminal prosecution. S.B. 1391 does not conflict with Proposition 57 but advances its stated intent and purpose to reduce the number of youths to be tried in adult court, reduce the number of incarcerated persons in state prisons, and emphasize rehabilitation for juveniles. Accordingly, we conclude S.B. 1391 is not an unconstitutional amendment of section 707 as modified by Proposition 57.

DISPOSITION

The petitions for writ of mandate are denied. To promote the interests of justice, this decision is final forthwith as to this court. (See Cal. Rules of Court, rule 8.490(b).) Pending finality of this decision, our previously issued *542stay orders dated January 31, 2019, remain in effect. Upon finality, those orders are vacated.

We concur:
