The Lieutenant Governor, on December 18 and 27, had issued the guidelines by which various steps including weightage to neighbourhood kids and abolition of 20 per cent management quota were taken.
"We have also enquired from the senior counsels for the appellants (schools) to how deprivation for admission through the management quota causes loss to the schools. The schools are not entitled to charge any capitation fee or any excess amount from the students admitted through management quota also.
"Though management quota has been recognised in several judgments but in relation to admission to professional courses, where merit is a criteria. It is not so here.
