The Supreme Court today rejected submissions seeking a stay on the ordinance allowing states to hold their separate medical entrance tests. <br/><br/>The Apex court had earlier ruled that there must be single common National Eligibility Entrance Test (NEET) for admission to MBBS and BDS courses. <br/><br/>However, the Centre then promulgated an ordinance which partially overturned the court's order and allowed states to conduct their own separate entrance tests for the current academic session.<br/><br/>Hearing pleas challenging this ordinance, the apex court cast doubts over it but did not stay it saying that the "interest of lakhs of students were involved"; and any interference at this stage would create "chaos", as more than 50 per cent states have already held their separate tests.
