1. IT is a prosecutable offence to Sale /Purchase an property that was originally alloted to a SC /ST person, since the property is alloted for his self-sustanance only and the property belongs to the State Govt. The State Govt., can reclaim it back and seize the property, without assigning any reason, whatsoever.
2. IF you are a POA holder of the SC /ST person, THEN you can apply to the district collector to convert the SC /ST's "new tenure property" into "old tenure property" (freehold), by paying the prescribed penalty /fine for the purposes, by following due procedures of law.
