Land registration pending

Hi.. I have recently purchased plot in visakhpatnam.It is a vmrda ( govt authorised layout) plot and loan has been provided by axis bank . One of my friend has been planned to take plot and payed the full amount - 50% white and 50% cash. Registration has been done.its been 2.5 months that registration is done and we have not yet received the document. As per the local information - registration is kept on pending p-174 due to inaam lands in the layout. How can the govt authority issues NOC to this layout and bank is also done the loan process. Almost 140 people have bought the land from this layout. My question - If thier is inaam lands - wat will happen to the people who purchased lands in that layout - it is a govt approved land. Who is accountable for this mistake. can we cancel this registration of my friend Can we get the stamp duty money back and wat is the process. Can I get the 100% money back from the layout agency or builder. If I go legally - on whom I need to file a case and how much time it will take to clear. We had taken the loan by doing some personal debts and selling of our gold etc.... Request the lawyers to suggest me on this.
