Hi Devadasan,
I am here to help you a little with my knowledge. This case was once filed in the court and under Congress, rule bill was also passed in the parliament. But still, there is nothing officially announced. But one thing I want to say his any student having SC certificate will eligible for SC reservation irrespective of caste, religion or community. If you don't have an SC certificate even though you are pure SC candidate you can't get a reservation. So it doesn't matter if you are Adi Dravida Christian or pure Christian what really matters for SC reservation during admission is your SC certificate.
I hope this will be helpful to you.
Thank you.
