  • Juvenile Justice (Care and Protection of Children) Act, 2015 (JJ Act)

Introduction 

This landmark judgment addresses the critical issue of age determination in juvenile justice cases and the applicability of the Juvenile Justice (Care and Protection of Children) Act, 2000 to cases pending when the Act came into force. 

  • The judgment was delivered by a Bench comprising Justice S.B. Sinha and Justice V.S. Sirpurkar on March 4, 2008. 
  • The case involved a criminal appeal arising from a murder case where the appellant claimed to be a juvenile at the time of commission of the offence. 

Facts 

  • The appellant was accused of murdering a schoolmate by stabbing him several times under Section 302 of the Indian Penal Code on May 12, 2000. 
  • The learned Magistrate estimated the appellant's age at approximately 17 years on the date of the incident. 
  • At the time of the offence, the Juvenile Justice Act, 1986 was in force, which defined a juvenile as a boy under 16 years of age. 
  • The Juvenile Justice (Care and Protection of Children) Act, 2000 came into force on April 1, 2001, raising the age of juvenility to 18 years for both boys and girls. 
  • Two medical boards were constituted to determine the appellant's age. The first board examined him on April 24, 2001, and opined his age to be between 18-19 years. The second board on June 29, 2001 gave an identical opinion. 
  • The appellant produced documents including a school certificate and horoscope to prove he was a juvenile, but these were found to be forged and fabricated, leading to criminal proceedings against the Head of the Institution. 

Issues Involved 

  • Whether the appellant was below 18 years of age as on April 1, 2001, when the JJ Act, 2000 came into force, thereby entitling him to protection under the new Act? 
  • What is the proper method of computing age when medical boards provide a range (18-19 years) rather than a definite age? 
  • Whether the minimum age determined by medical boards should be adopted in favor of the accused, given the beneficial nature of juvenile justice legislation? 
  • What evidentiary value should be given to medical board reports in determining age, particularly when documentary evidence is found to be fabricated? 
  • Whether the transitional provisions under Section 20 of the JJ Act, 2000 would apply to the appellant's case? 

Court's Observations 

  • The Court held that the JJ Act, 2000 is indisputably beneficial legislation, but its principles apply only to interpretation of statutes, not to determining factual questions of whether a person is a juvenile. 
  • The Court emphasized that whether an offender was a juvenile is essentially a question of fact to be determined based on materials brought on record by the parties. 
  • The Court reiterated that medical reports determining age have never been considered conclusive by courts or medical scientists, as exact age determination becomes difficult after a certain age through ossification or other tests. 
  • The Court noted that in numerous judgments, it has been held that age determined by doctors should be given flexibility of two years on either side. 
  • The Court observed that where two medical boards examined the appellant on different dates and reached identical opinions (age between 18-19 years), resulting in two different potential conclusions, the proper approach is to take the average of the ages. 
  • The Court emphasized, citing Pratap Singh v. State of Jharkhand (Constitution Bench), that the 2000 Act would apply to pending proceedings initiated under the 1986 Act only if the person had not completed 18 years of age as on April 1, 2001. 
  • The Court held that age determination must consider multiple factors, and entries in school registers have limited evidentiary value in the absence of materials on which the age was originally recorded.  
  • The Court noted that applying the averaging method to both medical board reports, the appellant's age as on April 1, 2001 would be above 18 years. 

Conclusion 

  • The Court dismissed the appeal, finding no merit in the appellant's claim of being a juvenile. 
  • The Court held that based on multiple factors—including forged documentary evidence and two consistent medical board reports—the courts below correctly determined that the appellant was above 18 years of age on April 1, 2001. 
  • The Court emphasized that it used the averaging method only for the specific case and did not intend to lay down a general proposition of law regarding age determination. 
  • The Court upheld that determination of age must be based on comprehensive evaluation of all available evidence, circumstances, and earlier court orders, applying consistent evidentiary standards under Section 35 of the Evidence Act.
