My part of the farmland is being taken by the Govt for 4 lane highway construction | Jharkhand

Dear All, My father has farmland in Jharkhand, Sahibganj dist.. 2 years back the narrow street was proposed to be transformed into Highway and this year it has been proposed to further extend to 4 lane highway road. Our property is on both side of the road and around 1.1 acres will be taken by the govt for that purpose. My father along with few others facing the same issue reached out to High court some 2 years back, in 2016 but no hearing till date. Actually the issue is the respected contractor is giving very undervalued rate for that fertile crop ladden land. moreover the contractor is giving different rates to different people. He has been looting the farmers there, he paid almost nothing to some of the adivasis. whose land was taken up. Now again those people are forcing us to accept the compensation and let them construct the road and since 2 years our case is not moving in the high court. Please suggest what can be done to egt the best price and at a speedy pace ? Since the land is very vaulable as its close to market area and water source too and now 4 lane high is going to come there but the associated farmers are not able to get the right value for their land. Some of them will loose theri only land where they cultivate and survive. So my dad is trying his best to fight for his and others rights. thanks in advance.
