Hi Deepak,

Yes, you can still participate in the special round with the previous seat in your hand in JOSAA as last year. You have to pay the participation amount again like for example if you paid 35000 for seat allotment you again have to pay some amount which obviously gets adjusted in the fee of the institution you end up in. Go for it if you surely want a seat out of JOSAA. The detailed information and procedure will be available on the website of csab. Stay tuned.

Good Luck !!
