The school superintendent in Readington has told parents he is rescinding after-school detentions given to the 29 students, who paid for their $2.00 lunches in pennies.
Officials say the students slowed down the lunch line and disrespected cafeteria workers.
Several parents had complained the punishment was too harsh, but some thought it too lenient.
In his e-mail to parents, the superintendent said the students described their actions as a prank and that news reports inaccurately called it a protest.
