delivered the opinion of the court:
This cause is a consolidated appeal from four appellate court decisions reviewing the findings of delinquency entered by the circuit court of Cook County, juvenile division, against six respondents. The issue concerns the nature and effect of the age factor in the definition of delinquent minors contained in the Juvenile Court Act (Ill. Rev. Stat. 1977, ch. 37, par. 702 — 2). (Although the causes arose in 1974, 1975, and 1976, the 1977 statutes will generally be cited for unamended provisions.)
Pursuant to petitions for adjudication of wardship, filed by the State and alleging the respondents had committed specified criminal offenses prior to their 17th birthdays, all six respondents were found delinquent. The findings of delinquency were entered following adjudicatory hearings after which the court determined each respondent had violated the specified criminal law beyond a reasonable doubt: Irish Greene, voluntary manslaughter (Ill. Rev. Stat. 1973, ch. 37, par. 702 — 2; Ill. Rev. Stat. 1973, ch. 38, par. 9 — 2(a)(1)); Edward Eicher and Gordon Dyess, aggravated battery (Ill. Rev. Stat. 1975, ch. 37, par. 702 — 2; Ill. Rev. Stat. 1975, ch. 38, par. 12 — 4(a)); Marvin Frazier, assault, aggravated assault, and unlawful use of a weapon (Ill. Rev. Stat. 1975, ch. 37, par. 702 — 2; Ill. Rev. Stat. 1975, ch. 38, pars. 12-l(a), 12-2(a)(l), 24 — 1(a)(2)); Michael Strickland, rape and robbery (Ill. Rev. Stat. 1975, ch. 37, par. 702-2; Ill. Rev. Stat. 1975, ch. 38, pars. 11 — 1, 18 — 1); Darnell Murff, armed robbery and unlawful restraint (Ill. Rev. Stat. 1975, ch. 37, par. 702 — 2; Ill. Rev. Stat. 1975, ch. 38, pars. 18 — 2, 10 — 3). Greene and Dyess were placed on one year’s probation. Eicher, Murff, Strickland and Frazier were committed to the Dlinois Department of Corrections, juvenile division.
On appeal, all six respondents challenged the adjudications of delinquency on the ground that the State had failed to prove beyond a reasonable doubt that respondents had committed the offenses on which the adjudications of delinquency were based, prior to their 17th birthdays. The Appellate Court, First District, Third Division, reversed the judgment against Greene (In re Greene (1978),
We hold that age is not an element which must be proved beyond a reasonable doubt in order to support an adjudication of delinquency. Delinquency is not a crime codified under our criminal laws. Rather, it is the commission of an otherwise unlawful act by one under 17 that triggers the application of the Juvenile Court Act (Ill. Rev. Stat. 1977, ch. 37, par. 701 — 1 et seq.). Age therefore is merely the factor which authorizes the application of the juvenile system. Once the State has properly alleged in the petition for adjudication of wardship that the respondent was under 17 years of age at the time of the commission of the offense which forms the basis for the petition (Ill. Rev. Stat. 1977, ch. 37, pars. 702 — 1, 702 — 2, 704 — 1), the authority of the court to proceed under the Juvenile Court Act has been asserted. Unless the respondent specifically challenges the authority of the court to proceed against him as a juvenile, the respondent is deemed to have consented to the juvenile proceedings and has waived any objections to the court’s authority to apply juvenile procedures and to impose juvenile sanctions upon him. The burden then lies on the State to prove the respondent’s guilt of the underlying offense beyond a reasonable doubt. Our conclusion is based primarily on an analysis of the Act and its purpose.
The Act establishes that its purpose is to care for and guide minors (Ill. Rev. Stat. 1977, ch. 37, par. 701 — 2(1); In re Armour (1974),
The specification of age in the delinquency provision of the Juvenile Court Act sets forth a class of minors whose cases are to be governed by the provisions of the Act. The petition for adjudication of wardship must allege, and the trial court at the adjudicatory hearing must determine, that the respondent is a delinquent (Ill. Rev. Stat. 1977, ch. 37, pars. 702 — 1, 704 — 1, 704 — 6). Section 2 — 2 of the Act defines a delinquent as “any minor who prior to his 17th birthday has violated or attempted to violate, regardless of where the act occurred, any federal or state law or municipal ordinance” (Ill. Rev. Stat. 1977, ch. 37, par. 702 — 2). That definition sets forth “jurisdictional facts” necessary for the institution of delinquency proceedings under the Act (Ill. Rev. Stat. 1977, ch. 37, par. 702 — 1), and the council commentary to an amendment to section 2 — 2 provides that “[t]he age differentiation between boys and girls with respect to the jurisdiction of the juvenile court in delinquency proceedings is abolished, and the jurisdictional limit for both sexes is established at under 17 years of age” (emphasis added) (Ill. Ann. Stat., ch. 37, par. 702 — 2, Council Commentary, at 59 (SmithHurd Supp. 1978)).
Thus the definition refers to age not as an element of delinquency but as a quasi-jurisdictional factor, the presence of which confers authority on the court to proceed under the Juvenile Court Act. It delineates the group encompassed by the category of delinquency as do other age designations for other classifications under the Act (Ill. Rev. Stat. 1977, ch. 37, pars. 701 — 13 (minors), 702 — 3 (minors otherwise in need of supervision), 702 — 4 (neglected minors), 702 — 5 (dependent minors)).
It is manifest, however, that the age factor in the definition of delinquency is not, technically, a jurisdictional requirement since the juvenile court is simply a division of the circuit court (Ill. Rev. Stat. 1977, ch. 37, par. 701-8; People v. Jiles (1969),
The situation of a respondent who remains silent about his age while proceeding to defend himself against an adjudication of delinquency under the Juvenile Court Act finds further analogy in cases which hold that a juvenile who wilfully misrepresents his age to an adult criminal court waives the statutory procedures which inure to juveniles accused of criminal offenses (Ill. Rev. Stat. 1977, ch. 37, par. 702 — 7; People v. Henderson (1971),
Section 4 — 6 of the Act provides that the standard of proof and rules of evidence in the nature of criminal proceedings are applicable to the determination of delinquency (Ill. Rev. Stat. 1977, ch. 37, par. 704 — 6). However, the Act’s purpose and logic indicate that this requirement attaches to the elements of the offense which form the basis for the delinquency proceeding, since it is not the age of the offender which is analogous to a crime but his conduct (see In re Urbasek (1967),
Since age is not an element which the State must prove, the general denials to the petitions for adjudication of wardship entered by the respondents here did not place in issue respondents’ ages and the court’s authority to proceed. The denials merely required the State to prove the elements of its case beyond a reasonable doubt (Ill. Rev. Stat. 1977, ch. 37, pars. 704 — 8, 704 — 6). Contrary to the respondents’ contentions, to require the respondent to specifically challenge the court’s authority to treat him as a juvenile once the State has invoked juvenile proceedings does not transform age into an affirmative defense without express authorization by the General Assembly (see People v. Smith (1978),
Our analysis of the Act and our disposition of these cases serve the protective purpose and policy of the Juvenile Court Act to care for and guide minors (Ill. Rev. Stat. 1977, ch. 37, par. 701 — 2(1)). They also serve the interest of minors in avoiding the stigma of a criminal prosecution and in receiving the benefits the Act intends to direct toward juvenile as opposed to adult offenders (see In re Beasley (1977),
The respondents argue that the statutory language is clear and thus precludes any judicial construction of the Juvenile Court Act to determine the meaning of the age factor in the delinquency provisions. However, the varying analyses and conclusions in the appellate court opinions reveal the apparent ambiguity which requires this court to examine the statutory language and purposes, as well as the consequences which would derive from alternate constructions of the age factor, to determine the legislative intent in including the age provision (see In re Armour (1974),
The Ohio case on which respondents place great reliance is inapposite since the Ohio juvenile court, unlike circuit courts in Illinois hearing juvenile cases, was a statutory court of limited jurisdiction, and the State had to show age in order to establish technical jurisdiction of the court over the alleged delinquent; the court in State v. Mendenhall (1969),
Respondents Eicher and Greene further argue that this court cannot and should not consider the State’s contention that they waived any objection to the authority of the court to apply the Juvenile Court Act since that argument was not raised in the petition for leave to appeal filed in their cases and since the State did not file a petition for leave to appeal from the judgment of the appellate court in Frazier’s case. Our rules provide, however, that a reviewing court may give any judgment which ought to have been given or which the case may require (58 Ill. 2d R. 366(5)). All six respondents raised the same issue on appeal to the appellate court, and the arguments raised by the State pose only possible resolutions of those same issues. Our rules further provide that any appellee may seek and obtain any relief warranted by the record on appeal without filing a separate petition for leave to appeal, notice of cross-appeal or separate appeal (58 Ill. 2d R. 318(a)).
In sum, while it is advisable for the State to establish a respondent’s age at the adjudicatory stage to avoid any possibility of an improper application of juvenile procedures, age is not an element of delinquency but is a factor which triggers the application of the Juvenile Court Act to young offenders. If the respondent does not challenge the authority of the court to proceed under the provisions of the Act, the respondent has consented to the court’s authority and has waived any objection to his treatment as a juvenile. Since none of the respondents challenged the authority of the circuit court, juvenile division, to proceed, we hold that the petitions for adjudication of wardship and findings of delinquency should have been affirmed.
The judgments rendered by the appellate court in favor of respondents Eicher and Greene, in cause Nos. 50784 and 50834, are reversed, and the adjudications of delinquency entered by the circuit court are affirmed. The judgment rendered by the appellate court in cause No. 50857 remanding the cause to determine Frazier’s age is reversed, and the finding of delinquency entered by the circuit court is affirmed. The judgment of the appellate court in cause No. 51156 affirming the findings of delinquency against Dyess, Murff and Strickland is affirmed.
50784 — Appellate court reversed; circuit court affirmed.
50834 — Appellate court reversed; circuit court affirmed.
50857 — Appellate court reversed; circuit court affirmed.
51156 — Judgment affirmed.
