Supreme Court coddles SC/ST students of IITs for failing exams

There are many cases where the Supreme Court of India has behaved in a rather wacky manner. This incident is one more in a long list. I'm against reservations of any sort(except on economic basis). In this case some SC/ST students filed a case that they could not be expelled from the IIT's on basis of poor performance.
The Supreme Court justices including CJ Balakrishnan said,

It is not in dispute that SC and ST are a separate class by themselves, and the creamy layer principle is not applicable to them. Article 46 of the Constitution enjoins upon the state to promote with special care the educational and economic interests of the weaker sections and protect them from social injustice and all forms of exploitation. These socially and economically backward categories are to be taken care of at every stage even in the specialised institutions like IITs.

After 60+ years the practice of continuing reservations based on castes is ridiculous. It has not served its purpose and continuing it is following a failed policy again and again where by the people who really deserve the reservations do not get it. What is worse is the CJI saying that SC/ST's should not have a creamy layer. Where is the justice for deserving candidates of other communities who have been denied those seats on the basis of caste?
These candidates were given their chances and more by the IIT's and yet they have failed. Now they want to disrespect other SC/ST students who have passed by virtue of merit by raising a ruckus in this case.

But, at the same time, we are conscious of the fact that the IIT-Delhi, in order to maintain and continue its high standards of education, implemented certain aspects which were helpful to the petitioners. But the fact remains that in spite of such efforts, these petitioners were not able to secure the minimum grades.

What else should the IIT's do, keep the pass score as 10/100?
