Ahead of the crucial hearing in the Supreme Court on Friday, the IIM-Bangalore on Thursday followed IIM-Ahmedabad in defying the human resource development ministry's decision to drastically reduce the fees of the business school and said it would continue to charge Rs 150,000 from its students.

In an affidavit before the apex court, IIM-B said of the total fee of Rs 152,000 charged from the students, it would appropriate Rs 30,000 and keep the rest in a separate non-lien account till the apex court took a decision on the issue, which was raised by a public interest litigation.

The IIM Controversy: Complete Coverage

The court had revived the hearing on the disposal of the PIL after the Centre refused to give a commitment not to tinker with the "autonomy" of the premier business schools though it had given an oral undertaking that reduction of the fees would not amount to interference with the functioning of the IIMs.

However, the court had made it clear that before going into the issue raised by the PIL litigants, it would test their locus standi to challenge the February 5 decision of the ministry reducing the fees from Rs 150,000 to Rs 30,000.

IIM-A had filed an affidavit before the apex court on April 13 stating that it would continue to charge Rs 158,000 from each student appropriating Rs 30,000 of it for the institution and keeping the rest in a non-lien account.
