While acquitting a young accused of sexual assault charges under the POCSO Act, Madras High Court made two significant suggestions that:
1. the age for the definition of a “child” be taken as 16 rather than 18, and
2. the Act account for the difference in age between the offender and the girl involved in consensual sex

With the intent to effectively address the evil of sexual exploitation and sexual abuse of children, Protection Of Children from Sexual Offences Act (POCSO) was passed by the parliament in the year 2012.
“Children” according to the Act are individuals aged below 18 years.
The Act is gender neutral.
Sexual assault is deemed to be “aggravated” under certain circumstances such as, when the child is mentally ill. Also when the abuse is committed by the person in a position of trust such as doctor, teacher, policeman, family member.
The Act stipulates that such steps must be taken which makes the investigation process as child-friendly as possible and the case is disposed off within one year from the date of reporting of the offence.
The Act provides for establishment of Special Courts for trial of such offences and matters related to it.
To monitor the implementation of the Act, the National Commission for the Protection of Child Rights (NCPCR) and State Commissions for the Protection of Child Rights (SCPCRs) have been made the designated authority. Both being statutory bodies.

The Madras High Court has that the Lieutenant-Governor (L-G) of Puducherry could not interfere with the day-to-day administration of the Union Territory when an elected government was in place.
The court said incessant interference from the L-G would amount to running a “parallel government.”
The LG of Delhi enjoys greater powers than the LG of Puducherry.
The LG of Delhi has “Executive Functions” that allow him to exercise his powers in matters connected to public order, police and land “in consultation with the Chief Minister.
Under the constitutional scheme, the Delhi Assembly has the power to legislate on all subjects except law and order and land.
However, the Puducherry Assembly can legislate on any issue under the Concurrent and State Lists.
However, if the law is in conflict with a law passed by Parliament, the law passed by Parliament prevails.
