As a tool of transformation of caste society, reservation worked and did not work. In the background of B.R. Ambedkar’s struggle for annihilation of caste, it started for Scheduled Castes (SCs )and Scheduled Tribes (STs) from 1947 itself in two sectors: education and employment and legislative bodies in the realm of the electoral system. Reservation for the Other Backward Classes (OBCs) began only in 1995 subsequent to implementation of the Mandal Commission report. The implementation process was accompanied by a conscious manipulation by the upper castes, which kept on denying the very existence of caste and refused to implement reservation in different structures.
