The Supreme Court had, on January 20, said that though, as per the Juvenile Justice Act, a plea regarding the age of the accused can be raised at any stage of the case, it cannot be raised repeatedly after it was rejected once.
The court stated that once a convict has chosen to take the plea of juvenility before the learned Magistrate, High Court and also before the Supreme Court and the said plea has been rejected up to the Supreme Court, the petitioner cannot be allowed to reagitate the plea of juvenility by filing a fresh application under Section 7A of the JJ Act.
In this case, it was being done just to stall the hanging on the convict and even the lawyer was fined for the delaying tactics.
