Dear Varun,
There chances that you may get a cacant seat but none can gurantee that because a ccording to the Counselling Guideline and information given in Revised CLAT 2018 Calendar after the closure of the CLAT Office, vacancy if any, in any NLU will be filled by the respective NLUs at their own level from the CLAT list in the order of merit as per the Rules and Regulations of the participating Universities. Here you need to focus on terms vacancy if any & CLAT list in the order of merit as per the Rules and Regulations of the participating Universities. I hope it helps.
