A same plot was sold by sahkari samiti to 3 persons.

I purchase a plot in Oct 2007. Mutaion was done in Dec 2007 , name was changed and new khasra number was allotted to me (say 2360/50). I has also paid desired fee to govt of CG for that plot. As per land record of CG (on line record )my name against above khasra number is available in B1 and P1. Recently it is came into knowledge that same plot was sold by committee to other person in 1990 and his name with different khasra number(2360/20) is also available in on line land record of CG govt . The same plot was again sold by committee to 3rd person in 2004 and his name with different khasra number(2360/40) is also available in on line land record of CG govt . Thus same plot has been sold to 3 person by committee . Committee had one big plot with khasra no. 2360. Committee has sold all the available land as per plotting. But in fraudulent way the land available for Road and pathway is available with committee and they are selling it and after selling every time new khasra number is assigned to new customer. What is legal solution ?
