The protesters warned they will stage a demonstration in front of parliament on May 9 if their demand is not accepted.
More than 100 school owners and teachers gathered outside the Rawalpindi Press Club led by Joint Action Committee of All Pakistan Private Schools and Colleges convenor Chaudhry Nasir Mehmood and Abrar Ahmed Khan.
They carried placards inscribed with slogans urging the chief justice to take notice of the closure of private schools in the cantonment areas.
Speakers said that for private school representatives had been protesting on the roads for the last three months but no action had been taken to save their institutions.
They alleged that cantonment authorities wanted to move out the private schools in order to increase enrolment in their own schools, which they said provide poor quality education. They also alleged that the Rawalpindi and Chaklala cantonment boards have increased the fee in their schools after issuing notices to private schools.
