Obviously, the 'only right which the petitioners can claim is the one which is available to them under Art. 14 of the Constitution. This Court in Kumari Jayshree v.

This Court further pointed out in that case that rules with retrospective operation can be made unless the exercise of such power is found to be violative of Art. 14 of the Constitution.
