Revision of the Central list Yes. The underlying philosophy of periodic revision is that reservation is for those backward classes who need it and who are handicapped without it and not for those who after availing themselves of and enjoying the benefits of reservation have ceased to be backward. Castes/communities which have advanced to the level of forward sections of the society should yield place to those who have not reached this stage of development and are in greater need of reservation. As such there is need for exclusion of such castes/communities which have advanced socially and educationally, from the list of backward classes.
