Why in News? 

A Bench of Justice JB Pardiwala and Justice Ujjal Bhuyan, in X v. State of Bihar & Anr. (2026), issued guidelines on the factors to be considered by the Juvenile Justice Board while conducting preliminary assessment under Section 15 of the Juvenile Justice (Care and Protection of Children) Act, 2015, while dismissing an appeal challenging the Patna High Court's ruling that the appellant be tried as an adult. 

What was the Background of X v. State of Bihar & Anr. (2026) Case? 

• The case arose from the alleged murder of a boy in Bihar in May 2022, where the victim's throat was allegedly slit with a knife. 
• The appellant, aged 16 years and four months at the time of the incident, was accused of the offence and was apprehended while attempting to flee. 
• The Juvenile Justice Board held that the appellant lacked the mental and physical capacity to commit the offence and decided to try him as a juvenile. 
• On an appeal filed by the complainant, the Sessions Court set aside the Board's order and directed that the juvenile be tried as an adult. 
• The Patna High Court affirmed the Sessions Court's ruling. 
• Aggrieved, the juvenile approached the Supreme Court. 

What were the Court's Observations? 

• On the Board's duty to independently assess all material: The Court held that the Juvenile Justice Board must apply its mind to all the materials available before it independently, and that the four parameters laid down under Section 15 of the JJ Act are distinct and must be considered both independently and collectively. 
• On preventing the assessment from becoming a mini-trial: The Court emphasised that the right to fair trial and the principle of presumption of innocence under the JJ Act must be balanced, and no inference should be made regarding the guilt or innocence of the accused while conducting the preliminary assessment. 
• On "mental capacity": The Court described mental capacity as a child's ability to make social decisions and judgments, extending it to cognitive abilities, developmental disability, comprehension, decision-making and reasoning, including the child's understanding of conflict and of the consequences of his actions. 
• On "physical capacity": The Court held that physical capacity is not restricted to the child's locomotor abilities, but must be assessed with regard to the nature of the act involved in the alleged offence, including whether the child, given his age and physical development, was physically capable of committing the offence in the manner alleged. 
• On "consequences" under Section 15: Relying on its earlier decision in Barun Chandra Thakur v. Bholu, the Court held that "consequences" must be read expansively to cover psychological and long-term effects on the victim, the child, and both families, and not merely the immediate physical harm. It noted that a child's intellectual awareness of risk does not necessarily translate into an ability to control impulsive behaviour, given the role of peer influence and emotional impulse at that age. 
• On expert opinion not being the sole criterion: The Court found that the Juvenile Justice Board had erred in basing its conclusion solely on expert opinion under Section 15(1), without any consideration of the Social Investigation Report (SIR) or Social Background Report (SBR), including the antecedents and recommendations of the Probation Officer and the Child Welfare Police Officer. It clarified that while Barun Chandra Thakur v. Bholu dealt with the significance of expert assistance, expert opinion cannot be the sole consideration in the Board's decision. 
• On additional factors for assessment: The Court referred to the Gujarat High Court's ruling in Child in Conflict with Law v. State of Gujarat, which listed eleven additional factors to be considered besides the SIR and SBR, including the child's antecedents and school and education records. 
• On the requirement of a reasoned decision: The Court made it mandatory for the Juvenile Justice Board to record a reasoned decision on whether the juvenile should be tried as an adult, including its reasons for accepting or rejecting the observations and recommendations in the SIR and SBR, assessing all material together in light of the four parameters under Section 15. 
• On Rule 10A of the JJ Model Rules, 2016: The Court reiterated the significance of Rule 10A, which authorises the Board to take the assistance of psychologists and psychosocial workers experienced in working with children in difficult circumstances, and which mandates that the Board assign reasons if it concludes that the juvenile be tried as an adult, observing that this requirement is not a mere procedural formality but a safeguard ensuring the Board's decision is capable of judicial scrutiny. 
• On relief granted: The Court upheld the findings of the Sessions Court and the Patna High Court and dismissed the appeal. 

What is Preliminary Assessment under Section 15 of the JJ Act? 

Section 15– Preliminary Assessment into Heinous Offences by Board 

Section 15(1): 

• Where a heinous offence is alleged to have been committed by a child who has completed, or is above, the age of sixteen years, the Board must conduct a preliminary assessment covering:  
  • the child's mental and physical capacity to commit the offence; 
  • his ability to understand the consequences of the offence; and 
  • the circumstances in which he allegedly committed the offence. 
• Based on this assessment, the Board may pass an order in accordance with Section 18(3). 
• Proviso: For conducting such assessment, the Board may take the assistance of experienced psychologists, psycho-social workers, or other experts. 
• Explanation: Preliminary assessment is clarified to not be a trial, but only an assessment of the child's capacity to commit, and understand the consequences of, the alleged offence. 

Section 15(2): 

• If the Board is satisfied, on preliminary assessment, that the matter should be disposed of by the Board itself, it must follow the procedure for trial in a summons case under the Code of Criminal Procedure, 1973, as far as may be. 
• First proviso: The Board's order to dispose of the matter is appealable under Section 101(2). 
• Second proviso: The assessment under this section must be completed within the period specified in Section 14.
