The Juvenile Justice Board (JJB) is the beating heart of the entire scheme for children in conflict with law. Sections 4 to 9 of the Juvenile Justice (Care and Protection of Children) Act, 2015 build it from the ground up — who sits on it, what makes them fit (or unfit) to sit, when and how it must meet, what it can do, and what happens when an ordinary magistrate stumbles upon a child in the dock. For judiciary and CLAT-PG aspirants, this block of sections is examined relentlessly because it sits at the intersection of structure, procedure and the constitutional promise of parens patriae. This chapter walks through each provision with the statutory text and the case law that fixes its meaning.

Where Sections 4-9 Sit in the Scheme

Chapter III of the JJ Act, 2015 (Sections 4 to 9) is titled Juvenile Justice Board and constitutes the adjudicatory machinery for one of the two categories of children the Act protects: the child in conflict with law (CICL). The other category — the child in need of care and protection — is handled by the Child Welfare Committee under Chapter V. This functional split is foundational; the Board never deals with care-and-protection cases, and the Committee never adjudicates offences. The constitutional anchor for this specialised, non-adversarial forum lies in Articles 15(3), 39(e), 39(f) and 45, which together authorise the State to make special provision for children and to secure their healthy development. For the wider rationale, see our chapter on the introduction, object and constitutional basis of the Act.

The Board is a creature of statute with the trappings of a court but a deliberately different temperament. It is required to be child-friendly, to sit in a place that does not resemble a regular courtroom, and to function as a Bench of Magistrates of First Class with the powers conferred by the Code of Criminal Procedure, 1973. Sections 4-9 give it its body (composition), its mind (powers and functions) and its rhythm (procedure). The hub page for the entire subject is the Juvenile Justice Act notes hub.

Constitution and Composition of the Board (Section 4)

Section 4(1) directs that, notwithstanding anything in the Code of Criminal Procedure, 1973, the State Government shall constitute for every district one or more Juvenile Justice Boards to exercise the powers and discharge the functions relating to children in conflict with law. The non obstante clause is significant: it ousts the ordinary criminal forum for CICL matters and vests adjudication exclusively in the Board.

Under Section 4(2), the Board consists of a Metropolitan Magistrate or a Judicial Magistrate of the First Class (not being a Chief Metropolitan Magistrate or Chief Judicial Magistrate) — designated the Principal Magistrate — with at least three years' experience, and two social workers selected as prescribed, of whom at least one shall be a woman. The Board thus forms a Bench, and a Magistrate sitting alone is not a Board. The mandatory inclusion of a woman member and of social workers reflects the rehabilitative, multidisciplinary philosophy the Act demands across its general principles of care and protection.

Section 4(3) requires that no social worker be appointed unless he or she has been actively involved in health, education or welfare activities pertaining to children for at least seven years, or is a practising professional with a degree in child psychology, psychiatry, sociology or law. Section 4(4) obliges the State Government to ensure that induction training and sensitisation of all members of the Board is provided within sixty days from the date of appointment — a provision examiners use to test attention to the Act's emphasis on trained, specialised adjudicators.

Qualifications, Disqualifications and Removal of Members

Section 4(5) builds in disqualifications to keep the Board fit for purpose. No person is eligible for selection as a member of the Board if he or she has any past record of violation of human rights or child rights; has been convicted of an offence involving moral turpitude (and such conviction has not been reversed); has been removed or dismissed from service of the Central or State Government or an undertaking or corporation owned or controlled by either; or has ever indulged in child abuse, employment of child labour, or any other violation of human rights or immoral act. These bars are intended to ensure that those who decide the fate of children carry no taint that would undermine the Act's protective purpose.

Section 4(6) provides for the term and tenure as prescribed by rules, while Section 4(7) deals with termination of the appointment of a member (other than the Principal Magistrate) after an inquiry by the State Government, where the member has been found guilty of misuse of power vested under the Act; has failed to attend the proceedings of the Board consecutively for three months without any valid reason; or has failed to attend less than three-fourths of the sittings in a year. The careful exclusion of the Principal Magistrate from this administrative removal power preserves judicial independence — the magisterial member's tenure is governed by service conditions, not by executive inquiry.

The Board as a Child-Friendly, Non-Adversarial Forum

Although the Board exercises powers of a Magistrate, the Act is emphatic that it must not behave like an ordinary criminal court. Section 7(3) requires that the Board sit at a place and conduct proceedings in a manner that is child-friendly, and that the child is not made to feel that he is in a courtroom. This is more than aesthetics: it operationalises the principle of dignity and the presumption of innocence that runs through the Act's scheme. The Supreme Court in Salil Bali v. Union of India (2013), while upholding the constitutional validity of the juvenile justice legislation and the eighteen-year threshold, reaffirmed that the system is designed to be reformative and rehabilitative rather than retributive — a temperament the Board's child-friendly procedure is meant to embody.

The same reformative philosophy explains why the Board's record-keeping, language and atmosphere are tightly regulated, and why a child's prior involvement with the Board generally attracts protections against disclosure and disqualification later in life. The Board's character is therefore not merely procedural decoration; it is the institutional expression of the Act's object, examined more fully in the chapter on procedure in relation to children in conflict with law.

Persons Who Cease to Be Children During Inquiry (Section 5)

Section 5 addresses a recurring practical problem: a child whose inquiry begins while he is below eighteen but who crosses that age before the proceedings end. The section provides that where an inquiry has been initiated in respect of any child under the Act, and during its course the person completes the age of eighteen years, the inquiry may be continued by the Board and orders may be passed in respect of such person as if such person had continued to be a child. The crossing of the age threshold mid-inquiry therefore does not divest the Board of jurisdiction or convert the proceeding into an ordinary criminal trial.

This provision codifies a principle the courts had developed under the earlier statutes — that the date of the offence, not the date of apprehension or trial, governs juvenility. The Constitution Bench in Pratap Singh v. State of Jharkhand, (2005) 3 SCC 551, settled precisely this question, holding that the relevant date for determining whether an accused is a juvenile is the date of commission of the offence, not the date on which he is produced before the competent authority. Pratap Singh also held that the 2000 Act applied to cases pending under the 1986 Act. Section 5 carries that logic forward into the 2015 framework.

Offences Committed While Below Eighteen (Section 6)

Section 6 complements Section 5 by dealing with a person who is apprehended after completing eighteen years for an offence committed while he was below eighteen. Section 6(1) provides that any such person shall, subject to the provisions of the section and notwithstanding anything contrary in the Code of Criminal Procedure, 1973, be treated as a child during the process of inquiry. Section 6(2) permits the Board to direct that, where such person is not released on bail by the Board, he be placed in a place of safety during the process of inquiry, and Section 6(3) requires that the person be treated, during the inquiry, in accordance with the procedure laid down under the Act.

The doctrinal foundation again traces to the principle that juvenility attaches to the date of the offence. In Hari Ram v. State of Rajasthan, (2009) 13 SCC 211, the Supreme Court explained the retrospective operation of the juvenile justice scheme and the mechanism (then Section 7-A of the 2000 Act) by which a claim of juvenility may be raised before any court at any stage, even after the person has ceased to be a juvenile. Sections 5 and 6 of the 2015 Act, read with the claim-of-juvenility machinery now in Section 9, together preserve this protection so that an adult-aged accused who was a child at the time of the offence is not denied the Act's benefits merely because of the passage of time.

Procedure in Relation to the Board and Quorum (Section 7)

Section 7 regulates the Board's internal functioning. Section 7(1) provides that the Board shall meet at such times and observe such rules of procedure regarding the transaction of business at its meetings as may be prescribed. Importantly, Section 7(2) allows a child in conflict with law to be produced before an individual member of the Board when the Board is not in sitting — a practical safeguard ensuring that a child is not detained merely because the full Board is unavailable.

Section 7(3) carries the child-friendly mandate already noted. Section 7(4) addresses the effect of absence of members: a Board may act notwithstanding the absence of any member, and no order made by the Board shall be invalid merely by reason of the absence of any member during any stage of the proceeding. There is, however, a crucial proviso — there shall be at least two members, including the Principal Magistrate, present at the time of final disposal of the case and while making an order under Section 18(3) (the order directing trial as an adult). Section 7(5) provides that in the event of a difference of opinion among members, the majority opinion prevails, but where there is no majority, the opinion of the Principal Magistrate prevails. Aspirants should commit the quorum rule to memory: routine business may proceed with reduced membership, but final disposal and a Section 18(3) transfer order require the Principal Magistrate plus at least one more member.

Powers, Functions and Responsibilities of the Board (Section 8)

Section 8 is the powerhouse provision. Section 8(1) confers on the Board the power to deal exclusively with all proceedings under the Act relating to children in conflict with law, in the area of its jurisdiction. This exclusivity is the statutory expression of the principle that no ordinary criminal court may try a child; the matter must come to, or be transferred to, the Board.

The exclusivity was authoritatively affirmed in Subramanian Swamy v. Raju (through Member, Juvenile Justice Board), (2014) 8 SCC 390, arising from the December 2012 Delhi gang-rape, where the Supreme Court held that the Juvenile Justice Act is a complete code that provides exclusively for children in conflict with law, and that the Board alone has jurisdiction over a juvenile irrespective of the gravity of the offence. The Court declined to read down the Act to permit a juvenile to be tried by an ordinary criminal court, locating the policy choice firmly within the legislative domain. This case is the cornerstone authority on the Board's exclusive jurisdiction and is frequently paired in examinations with the constitutional-validity holding in Salil Bali.

Section 8(2) enumerates the Board's wide-ranging functions and responsibilities, which include: ensuring the informed participation of the child and the parent or guardian in every step of the process; ensuring that the child's rights are protected throughout the apprehension, inquiry, aftercare and rehabilitation; ensuring availability of legal aid; directing the Probation Officer or social worker to undertake a social investigation report; adjudicating and disposing of cases of children in conflict with law in accordance with the process of inquiry under Section 14; transferring matters to the Child Welfare Committee where a child is found to be a child in need of care and protection; conducting inquiry for declaring fit persons regarding care of children; conducting at least one inspection visit per month of residential facilities for children in conflict with law; and ordering the police to register an FIR for offences committed against any child in conflict with law where the Board is satisfied an offence has been committed.

Magistrates Not Empowered and the Claim of Juvenility (Section 9)

Section 9 is the gateway through which children wrongly brought before ordinary courts are routed back to the Board, and it codifies the claim-of-juvenility jurisprudence. Section 9(1) provides that where a Magistrate not empowered to exercise the powers of the Board under the Act is of the opinion that the person alleged to have committed the offence and brought before him is a child, he shall, without any delay, record such opinion and forward the child immediately along with the record to the Board having jurisdiction.

Section 9(2) is the heavily litigated limb. It provides that, in any case, a person can claim before any court that he was a child on the date of commission of the offence, even after final disposal of the case, and even if no such claim was raised earlier and the person has ceased to be a child; the court shall make an inquiry, take such evidence as is necessary (but not an affidavit) to determine the age, and record a finding whether the person was a child on the date of the offence. Crucially, if the court finds the person was a child, it shall forward the child to the Board for passing appropriate orders, and the sentence, if any, passed by the court shall be deemed to have no effect. This provision continues, in stronger form, the protection earlier housed in Section 7-A of the 2000 Act and explained in Hari Ram v. State of Rajasthan.

Age Determination: The Hierarchy of Evidence

Because juvenility is jurisdictional, the manner of proving age is litigated constantly before the Board. The settled hierarchy — now reflected in the Act and the Model Rules — gives first preference to the date of birth certificate from the school (or matriculation certificate); in its absence, the birth certificate issued by a corporation, municipal authority or panchayat; and only in the absence of both, the ossification or other medical age determination test. The Supreme Court in Jarnail Singh v. State of Haryana, (2013) 7 SCC 263, held that the procedure for age determination under the (then) Rule 12 of the Juvenile Justice Rules, 2007 — designed for a child in conflict with law — applies equally to determining the age of a child who is a victim of crime, thereby unifying the evidentiary standard.

The limits of medical evidence are equally well settled. In Mukarrab v. State of Uttar Pradesh, (2017) 2 SCC 210, the Court reiterated that the ossification test is not conclusive of age, that radiological examination leaves a margin of roughly two years on either side, and that a court cannot adopt a blind and mechanical view based solely on medical opinion — particularly where the person has crossed thirty years of age. The first attempt at age determination is by assessing physical appearance when the child is produced; only where doubt persists does the Board proceed to documentary and medical evidence. The interplay of these rules with the statutory definitions of "child" and "age" is a frequent examination theme.

Preliminary Assessment and the Board's Gatekeeping Role (Section 15)

Although the preliminary-assessment power sits in Section 15 rather than in Sections 4-9, it is exercised by the Board and is inseparable from an understanding of the Board's procedure. Where a child above the age of sixteen years is alleged to have committed a heinous offence, the Board must conduct a preliminary assessment with regard to the child's mental and physical capacity to commit the offence, the ability to understand the consequences of the offence, and the circumstances in which the offence was allegedly committed. This assessment is not a trial; it is a screening to decide whether the child should be tried as an adult by the Children's Court under Section 18(3).

The Supreme Court in Barun Chandra Thakur v. Master Bholu (2022) examined the contours of this Section 15 assessment, emphasising the need for procedural fairness, the assistance of experienced psychologists or experts where required, and a reasoned order — given the far-reaching consequence of transferring a child to the adult stream. The Court underscored that the assessment determines a jurisdictional fact and cannot be a mechanical exercise. For the substantive law on what counts as a heinous offence and how the adult-trial route operates, see the chapters on heinous offences and children aged 16-18 and trial of children as adults.

The 'Heinous Offence' Question and the Fourth Category

The Board's gatekeeping power under Section 15 turns on the definition of "heinous offence" in Section 2(33) — an offence for which the minimum punishment under the Penal Code or any other law is imprisonment for seven years or more. A definitional gap arose for offences carrying a maximum of more than seven years but no minimum, or a minimum of less than seven years. In Shilpa Mittal v. State of NCT of Delhi, (2020) 2 SCC 787, the Supreme Court held that such offences — described as the "fourth category" — do not fall within the definition of heinous offences, because the statute speaks of a minimum sentence of seven years. The Court declined to judicially expand the definition, holding that the gap must be filled by the legislature, and directed that pending legislative correction such fourth-category offences be treated as serious offences rather than heinous ones.

The practical consequence for the Board is significant: a sixteen-or-seventeen-year-old accused of a fourth-category offence cannot be subjected to a Section 15 preliminary assessment for adult trial, and must be dealt with under the ordinary inquiry process. Shilpa Mittal is therefore essential reading alongside Sections 4-9 because it delimits when the Board's most consequential power may even be invoked.

Inquiry Timelines and Disposal

The Board's procedure is governed by strict timelines that examiners expect candidates to know precisely. Under Section 14, the inquiry by the Board must ordinarily be completed within four months from the date of first production of the child, extendable by a further two months for reasons to be recorded in writing. For petty offences, failure to complete the inquiry within six months results in termination of the proceedings. Where a preliminary assessment under Section 15 is required, it must be completed within three months from the date of first production.

These compressed timelines reflect the Act's recognition that delay is itself a harm to a child and that prolonged uncertainty undermines rehabilitation. The Board's exclusive jurisdiction under Section 8, its quorum rules under Section 7, and its routing power under Section 9 all operate within this time-bound framework. Taken together, Sections 4-9 create a forum that is specialised in personnel, restricted in who may staff it, exclusive in jurisdiction, child-friendly in atmosphere, and disciplined by statutory deadlines — the architecture every aspirant must be able to reproduce.

Frequently asked questions

Who are the members of the Juvenile Justice Board under Section 4?

The Board comprises a Principal Magistrate — a Metropolitan Magistrate or Judicial Magistrate of the First Class (not a Chief Metropolitan or Chief Judicial Magistrate) with at least three years' experience — and two social workers selected as prescribed, of whom at least one must be a woman. Each social worker must have at least seven years' active involvement in child-related health, education or welfare work, or be a practising professional with a degree in child psychology, psychiatry, sociology or law.

What is the quorum for the Board's final orders under Section 7?

The Board may generally act despite the absence of a member, and no order is invalid merely because a member was absent at some stage. However, at the time of final disposal of a case, and when passing an order under Section 18(3) directing trial as an adult, there must be at least two members present, including the Principal Magistrate. Where members differ, the majority opinion prevails, and if there is no majority, the opinion of the Principal Magistrate prevails.

Does the Board lose jurisdiction if the child turns eighteen during the inquiry?

No. Under Section 5, where an inquiry has begun and the person completes eighteen years during its course, the Board may continue the inquiry and pass orders as if the person had continued to be a child. This codifies the Constitution Bench holding in Pratap Singh v. State of Jharkhand (2005) that juvenility is reckoned on the date of the offence, not the date of production or trial.

Can a person claim juvenility after the case is over?

Yes. Section 9(2) permits a person to claim before any court that he was a child on the date of the offence, even after final disposal and even if the claim was not raised earlier or the person has since ceased to be a child. The court must inquire, determine the age, and if it finds the person was a child, forward him to the Board; any sentence already passed is deemed to have no effect. This continues the principle explained in Hari Ram v. State of Rajasthan (2009).

Does the Board have exclusive jurisdiction even over serious or heinous offences?

Yes. Section 8(1) gives the Board power to deal exclusively with all proceedings relating to children in conflict with law. In Subramanian Swamy v. Raju (2014) 8 SCC 390, arising from the Delhi gang-rape case, the Supreme Court confirmed that the Juvenile Justice Act is a complete code and that the Board alone has jurisdiction over a juvenile, irrespective of the gravity of the offence. The adult-trial route under Sections 15 and 18(3) is itself initiated by the Board, not by an ordinary criminal court.

How is age determined when the Board doubts a person's juvenility?

The Board first assesses physical appearance; where doubt persists, it follows a documentary hierarchy — the school or matriculation date of birth certificate first, then the birth certificate of a corporation, municipality or panchayat, and only in the absence of both, an ossification or medical test. Jarnail Singh v. State of Haryana (2013) 7 SCC 263 applied this procedure to both accused and victim children, while Mukarrab v. State of U.P. (2017) 2 SCC 210 held that the ossification test is not conclusive and leaves a margin of about two years on either side.
