The fate of the 4.5% minority sub-quota within the 27% Other Backward Classes quota net looked uncertain with the Supreme Court saying it was “very unhappy” about the manner in which the reservation scheme was created, and refused to stay the judgment of the Andhra Pradesh high court quashing it. “How did you determine 4.5%? Why now? Where is the material?” were some of the questions the SC put to attorney general G E Vahanvati when he stood up to argue the HRD ministry’s appeal against the HC’s May 28 judgment striking down the Muslim sub-quota on the grounds that it was violative of the constitutional injunction against faith-based quota. The SC’s refusal to stay the HC verdict —combined with its remarks about the way the government went about the subquota—leaves 325 students, falling in the minority sub-quota and aspiring to join the IITs, on tenterhooks.
