Hi
1) Since your land was acquired free of cost for the purpose of provision of road and more so that the land acquisition award also has been passed, it is the imperative duty of the municipality to lay the road as per approved master plan and sketch.
2) The executive engineer cannot now back track stating that the acquisition sketch is not proper etc. Looks like he is already purchased by the persons/politicians having vested and enimical interests.
3) The executive engineer has to abide by the approved master plan and road construction plan on the basis of which the land was acquired.
4) First file a complaint with mangalore corporation and ask them to lay the road.
5) if they(Mangalore Municipal corporation) do not respond to you approach the high court and file a writ of mandamus seeking the court to issue directions to lay the road as per approved road plan.
6) Once the high court issues orders(which in your case, will be a very easy order for the high court to pass), municipality will have no options other than to lay down the road as per approved plan.
Hope this helps.
