Directive Principles [SEP] Implementation
Welfare schemes for the weaker sections are being implemented both by the Central and State governments. These include programmes such as boys' and girls' hostels for scheduled castes' or scheduled tribes' students. The year 1990–1991 was declared as the "Year of Social Justice" in the memory of B.R. Ambedkar. The government provides free textbooks to students belonging to scheduled castes or scheduled tribes pursuing medicine and engineering courses. During 2002–2003, a sum of Rs. 47.7 million was released for this purpose. In order that scheduled castes and scheduled tribes are protected from atrocities, the Government enacted the Prevention of Atrocities Act, which provided severe punishments for such atrocities.
