A bench headed by Justice B S Chauhan issued notice and asked the Ministry of Women and Child Development to respond within four weeks to the plea that a criminal court cannot be "ousted" from judicial function to try juveniles for offences covered under IPC.
It sought the Centre's views on the question as to who will decide the maturity of an offender, who is above 16 and below 18 years of age, in matters relating heinous offences.
At the start of hearing, it was alleged the legislature lacked powers to interfere with judicial functions and certain provisions of the Juvenile Justice (Care and Protection of Children) Act be declared as "unconstitutional" to the extent they puts a "blanket ban" on powers of criminal courts to try a juvenile offender for offences under IPC.
