I am excited to reply. With Art.338-338A in place this question arising out of Art. 341 and 342 comes to a rest.
Art.338 envisages the formation of National Commission for Sceduled Castes with autonomy to inquire [(Art.338 (5) (b)] specific complaints with respect to the deprivation of rights and safeguards of the Sceduled Castes with powers of a Civil Court. Matters relating to state is forwarded to the concerned state governor who along with the report submits the details of action taken to the Legislature of the state. So in the process of taking action on the said report by the Governor, the Sceduled Castes and Sceduled Tribes (Prevention of Atrocities) Act,1989 is set in motion.
Ditto for Sceduled Tribes with Art.338 A.
Plese permit me to feel that SC&ST (POA) Act,1989 is just meant to outreach to dispense justice,else normal law of the land when followed in letter and spirit is effective,more effective for the subject.
I marvel at the vision of the architect of our Constitution.
