Sir, There is a Gram panchayat barren land in my village on which patwari has helped to make in grab by some person.I have complaint many times to authorities concerned at district level as well as state level but patwari is forwarding his fake report and changing his statements and maps in his every report by concealing the original/ official land maps and land records.Now I am in state of helplessness as i have submitted my complaints several times to district and state authorities as well.May i file a writ in high court in this regard.Sir please guide me the further course of action.
