The six-year-old was allegedly attacked in the toilet of the Brightland School in Triveni Nagar here by the girl on January 17.
She was granted interim bail earlier and the regular bail plea was to be heard yesterday, but the matter was deferred for today.
The counsel for the boy today pleaded that the age of the girl should be determined on the basis of medical examination.
However, the girl's counsel argued that it should be determined on the basis of school certificates.
Taking note of the incident after the picture of the wounded boy went viral on social media and TV channels, District Inspector of Schools (DIoS), Lucknow, Mukesh Kumar Singh had issued a notice to the school seeking clarification as to why legal action should not be initiated against it.
